(First embodiment)
[Configuration and basic operation]
(Configuration of the entire information distribution system)
FIG. 1 is a diagram showing a configuration of an information distribution system according to the first embodiment of the present invention.

  Referring to FIG. 1, an information distribution system 201 according to the first embodiment of the present invention includes a smart meter (information distribution device) 101, control devices (devices) 102A and 102B, and a plurality of electric devices 161. Is provided. Hereinafter, each of the control devices 102A and 102B is also referred to as a “control device 102”.

  The smart meter 101 transmits and receives various types of information to and from the management server 151 that manages the information distribution system 201 via a power line or the Internet. Specifically, the smart meter 101 is a power meter with a communication function, and transmits a measurement result or the like to the management server 151. The smart meter 101 receives distribution information from the management server 151 (“A route” shown in FIG. 1). This distribution information includes a plurality of pieces of time-series element information such as daily or hourly electricity rate information.

  The smart meter 101 is connected to the control device 102 via a power line or the like, and transmits part or all of the distribution information received from the management server 151 to the control device 102 (“B route” shown in FIG. 1).

  The control device 102 is a device used in, for example, a HEMS (Home Energy Management System), and manages a plurality of devices. That is, the control device 102 is connected to one or a plurality of electric devices 161 by wire or wirelessly, and manages the electric device 161 using a part or all of distribution information received from the smart meter 101.

  For example, when the control device 102 receives the electricity charge information for each day or time zone from the smart meter 101, the control device 102 operates in the power saving mode for the air conditioner that is the electric device 161 based on the received electricity charge information. Or control so that the storage battery, which is the electric device 161, is charged in a time zone where the electricity rate is relatively low.

(Configuration of smart meter)
FIG. 2 is a diagram showing the configuration of the smart meter shown in FIG.

  Referring to FIG. 2, smart meter 101 includes an acquisition unit 11, a storage unit 12, a setting unit 13, a notification unit 14, a providing unit 15, and a receiving unit 16.

  The acquisition unit 11 receives distribution information from the management server 151. For example, the acquisition unit 11 receives distribution information including “electricity information on the day”, “electricity information on the next day”, and “electricity information on the next day” as element information from the management server 151. And the acquisition part 11 outputs the received delivery information to the memory | storage part 12, and the memory | storage part 12 memorize | stores this delivery information.

  The setting unit 13 gives an ID (Identification) to each element information of the distribution information stored in the storage unit 12. For example, the acquisition unit 11 assigns “ID1” to “electricity information on the day”, “ID2” to “electricity information on the next day”, and “ID3” to “electricity information on the next day” To do.

  Further, the setting unit 13 uses the distribution information stored in the storage unit 12 to generate target information (hereinafter also referred to as “instance”) including part or all of the element information included in the distribution information. To do. Then, the setting unit 13 sets identification information (hereinafter also referred to as “instance code”) for each of the control devices 102A and 102B in the generated instance. This instance code is information to be notified to the smart meter 101 when the control devices 102A and 102B specify arbitrary element information to the smart meter 101.

  For example, the setting unit 13 generates an instance for each of the control devices 102A and 102B, and sets an instance code for each generated instance.

  FIG. 3 is a diagram illustrating a specific example of an instance generated by the setting unit illustrated in FIG.

  That is, as illustrated in FIG. 3A, the setting unit 13 generates an instance for the control device 102A and sets the instance code “01” for the instance. The instance in which the instance code “01” is set is hereinafter referred to as “instance 01”.

  Also, as shown in FIG. 3B, an instance for the setting unit 13 and the control device 102B is generated, and an instance code “02” is set for the instance. The instance to which the instance code “02” is assigned is hereinafter referred to as “instance 02”.

  For example, the setting unit 13 has the same element information for both “instance code 01” and “instance code 02”, that is, “electricity information on the day” with “ID1” and “ID2”. The instance is generated so as to include “electricity information on the next day” and “electricity information on the next day” assigned with “ID3”.

  The setting unit 13 does not necessarily have to generate an instance for each of the control devices 102A and 102B. If the contents of the instance are common to the control devices 102, the setting unit 13 may generate one instance. Good. That is, the setting unit 13 may be configured to set the instance code of the instance for each of the control devices 102A and 102B.

  The instance may be distribution information itself. In such a case, the setting unit 13 can handle the distribution information as an instance without generating an instance.

  Referring to FIG. 2 again, the notification unit 14 notifies the corresponding control device 102 of the instance code set by the setting unit 13.

  When the control device 102A specifies the element information included in the instance to the smart meter 101, for example, the specification information specifying the instance code “01” and any element information included in the “instance 01”, Specifically, the ID assigned to the element information is notified.

  When the control device 102B specifies element information included in the instance for the smart meter 101, for example, the specification information specifying the instance code “02” and arbitrary element information included in “instance 02”; Specifically, the ID assigned to the element information is notified.

  When receiving the instance code and the designation information ID from the control device 102, the receiving unit 16 outputs the received instance code and ID to the storage unit 12, and the storage unit 12 receives the instance code and the ID received from the receiving unit 16. The ID is associated and stored.

  FIG. 4 is a diagram illustrating a specific example of the correspondence between the instance code and the ID stored in the storage unit illustrated in FIG.

  That is, referring to FIG. 4, for example, when instance code “01” and “ID1” are notified from control device 102A, storage unit 12 stores instance code “01” and “ID1” in association with each other. . For example, when the instance code “02” and “ID2” are notified from the control device 102B, the storage unit 12 stores the instance code “02” and “ID2” in association with each other.

  Referring to FIG. 2 again, providing unit 15 receives an information request from control device 102. This information request includes, for example, an instance code and does not include designation information such as ID.

  When receiving the information request, the providing unit 15 uses the storage content stored in the storage unit 12, that is, the control device 102 that has transmitted the information request using the instance code and ID notified from the control device 102. Specify the element information of the requested instance. Then, the providing unit 15 transmits the identified element information to the control device 102.

  Specifically, the providing unit 15 uses the instance code from the control device 102A when the instance code “01” and “ID1” are stored in the storage unit 12 as the instance code and ID notified from the control device 102A. When an information request including “01” is received, the information of “ID1” included in “Instance 01” in which the instance code “01” is set, for example, “electric charge information on the day” is specified, The identified element information is transmitted to the control device 102A.

  The providing unit 15 also uses the instance code “02” from the control device 102B when the instance code “02” and “ID2” are stored in the storage unit 12 as the instance code and ID notified from the control device 102B. When an information request including “instance 02” in which the instance code “02” is set is received, information “ID2” included in “instance 02”, for example, “electricity information on the next day” is specified. Information is transmitted to the control apparatus 102A.

[Operation]
Next, the operation of the information distribution system according to the first embodiment of the present invention will be described with reference to the drawings.

  FIG. 5 is a sequence diagram defining an information distribution procedure by the information distribution system according to the first embodiment of the present invention.

  Each device in the information distribution system 201 includes a computer, and an arithmetic processing unit such as a CPU in the computer reads and executes a program including a part or all of each step in the following sequence diagram from a memory (not shown). Each of the programs of the plurality of apparatuses can be installed from the outside. The programs of the plurality of apparatuses are distributed while being stored in a recording medium.

  Referring to FIG. 5, first, smart meter 101 receives distribution information from management server 151 (step S11). Here, the smart meter 101 receives from the management server 151 distribution information including the electricity price information of the current day, the next day, and the next day as element information.

  Next, the smart meter 101 assigns an ID to each element information included in the distribution information received from the management server 151 (step S12).

  Next, when the control device 102A transmits a device information inquiry to the smart meter 101 (step S13), the smart meter 101 receives the device information inquiry and performs a message analysis on the device information inquiry. The IP address of the device that is the transmission source of the device information inquiry and the device type information of the device that is the transmission source are acquired (step S14).

  Next, the smart meter 101 generates an instance for the device having the acquired IP address and device type information using the distribution information, and sets an instance code in the generated instance. Here, the smart meter 101 sets the instance code “01” to the instance for the device having the acquired IP address and device type information (step S15).

  Next, the smart meter 101 transmits the device type code assigned to itself and the instance code “01” to the control device 102A as a device information response (step S16).

  Here, it is assumed that there is a device information inquiry interruption by the control device 102B. That is, when the control device 102B transmits a device information inquiry to the smart meter 101 (step S17), the smart meter 101 receives the device information inquiry and performs a message analysis on the received device information inquiry. Then, the IP address of the device that is the transmission source of the device information inquiry and the device type information of the device that is the transmission source are acquired (step S18).

  Next, the smart meter 101 determines whether the newly acquired IP address and the previously acquired IP address are the same, the newly acquired device type information, the previously acquired device type information, To see if they are the same.

  Here, the IP address and device type information acquired in step S18 are the IP address and device type information of the control device 102B, and the IP address and device type information acquired in step S14 are the IP address of the control device 102A. And device type information. For this reason, the smart meter 101 determines that at least one of the newly acquired IP address and the previously acquired IP address, or the newly acquired device type information and the previously acquired device type information is not the same. .

  When the smart meter 101 determines that the newly acquired IP address and the previously acquired IP address are not the same, or the newly acquired device type information and the previously acquired device type information Are determined not to be the same, an instance for a device having a newly acquired IP address and device type information is generated. Then, the smart meter 101 sets an instance code for the generated instance. Here, the smart meter 101 sets the instance code “02” to the instance for the device having the newly acquired IP address and device type information (step S19).

  Next, the smart meter 101 transmits the device type code assigned to itself and the instance code “02” to the control device 102B as a device information response (step S20).

  The smart meter 101 determines that the already acquired IP address is the same as the newly acquired IP address, and the already acquired device type information is the same as the newly acquired device type information. If it is determined that there is, that is, the device that has transmitted the device information inquiry earlier and the device that has transmitted the device information inquiry later are the same, the smart meter 101 generates a new instance, for example, The instance code “01” of the already generated instance is transmitted as a device information response.

  Next, when the control device 102A transmits an ID notification request for inquiring the type of element information included in “instance 01” corresponding to the instance code notified from the smart meter 101 to the smart meter 101 ( In step S21), the smart meter 101 receives this ID notification request, and transmits the type of element information included in “instance 01” as an ID notification response.

  Here, “instance 01” is assigned “ID1” with “electricity information on the day”, “ID2” with “electricity information on the next day”, and “ID3” with “ID3”. It is assumed that “the electricity bill information for the next day” is included. In this case, in the smart meter 101, the types of element information corresponding to “ID1” to “ID3” are “electricity information on the current day”, “electricity information on the next day”, and “electricity information on the next day”, respectively. A list indicating this is transmitted to the control apparatus 102A as an ID notification response (step S22).

  Next, the control apparatus 102A receives an ID notification response from the smart meter 101, specifies an ID of arbitrary element information from among the element information included in “instance 01”, and is an instance that is identification information of target information The code and the ID that is the designation information are notified. For example, the control information 102A notifies the instance code “01” and “ID1” when it is desired to acquire “electric charge information on that day” (step S23).

  Then, the smart meter 101 stores the instance code and ID notified from the control device 102A, for example, the instance code “01” and “ID1” in association with each other (step S24).

  Further, here, when the control device 102B transmits an ID notification request for inquiring element information included in “instance 02” corresponding to the instance code notified from the smart meter 101 to the smart meter 101 ( In step S25), the smart meter 101 receives this ID notification request, and transmits the type of element information included in “instance 02” as an ID notification response.

  Here, “instance 02”, like “instance 01”, “electric charge information on the day” with “ID1”, “electric charge information on the next day” with “ID2”, and It is assumed that “next-day electricity charge information” with “ID3” is included. In this case, the smart meter 101 indicates that the element information corresponding to “ID1” to “ID3” is “electricity information on the current day”, “electricity information on the next day”, and “electricity information on the next day”, respectively. The list shown is transmitted to the control apparatus 102B as an ID notification response (step S26).

  Next, the control device 102B receives the ID notification response from the smart meter 101, specifies the ID of any element information from the element information included in the “instance 02”, and is an instance that is identification information of the target information The code and the ID that is the designation information are notified. For example, the control information 102B notifies the instance code “02” and “ID2” when it is desired to acquire “electricity information on the next day” (step S27).

  Then, the smart meter 101 stores the instance code and ID notified from the control device 102B, for example, the instance code “02” and “ID2” in association with each other (step S28).

  Next, when the control device 102A notifies the smart meter 101 of the instance code “01” set to itself and the information request (step S29), the smart meter 101 uses the stored contents stored in step S24. Then, “ID1” associated with the instance code “01”, for example, “electric charge information on the day” is specified as element information to be transmitted. Then, the smart meter 101 transmits the identified element information to the control device 102A as an information request response (step S30).

  Further, when the control device 102B notifies the smart meter 101 of the instance code “02” set in itself and the information request (step S31), the smart meter 101 uses the stored contents stored in step S28. “ID2” associated with the instance code “02”, for example, “electricity information on the next day” is specified as element information to be transmitted. Then, the smart meter 101 transmits the identified element information as an information request response to the control device 102B (step S32).

  In the above-described example, the case where the smart meter 101 transmits the electricity bill information to the control devices 102A and 102B has been described. However, the information transmitted from the smart meter 101 may be other types of information.

  In the above-described example, the case where the information request is notified by the control device 102 after the ID notification is performed by the control device 102 has been described. However, the control device 102 does not include the information request in the ID notification. Notifications can be included. When the smart meter 101 receives a notification of an ID including a notification of an information request from the control device 102, the smart meter 101 transmits element information corresponding to the notified ID to the control device 102.

  By the way, in the device management system described in Patent Document 1 described above, a device management apparatus that manages various electrical devices designates specific electrical devices to transmit or receive information, thereby managing the electrical devices. Is called.

  Here, when the device management apparatus transmits information to various electrical devices, first, when the information desired by the electrical device is specified and requested to the device management device, the device management device sends the specified information to the electrical device. Send.

  However, when there are a plurality of electrical devices managed by the device management apparatus, various electrical devices specify and request information at an arbitrary timing. Sometimes. For example, when information is specified by another electric device between the specification and request of information by a certain electric device, it is specified for the electric device for which information has been specified first. There is a possibility that information different from the received information will be transmitted.

  On the other hand, in the smart meter 101 in the information distribution system 201 according to the first embodiment of the present invention, the setting unit 11 sets the instance code of the instance that the control device 102 should notify to the smart meter 101 of itself. Set for each control device 102. Further, the notification unit 14 notifies the corresponding control device 102 of the instance code set by the setting unit 11. Further, the storage unit 12 stores an instance code notified from the control device 102 and an ID for designating element information for each instance code. Further, the providing unit 15 identifies the element information of the instance requested by the control device 102 based on the instance code and the element information ID stored in the storage unit 12, and provides the identified element information to the control device 102. .

  As described above, the configuration in which the instance code of the instance used when the control device 102 designates the element information of a certain instance is set for each control device 102 allows the element information designated by the certain control device 102 to include a plurality of elements in the instance. Which element information of the information can be specified accurately. That is, it is possible to prevent element information different from element information designated by each control device 102 from being provided to each control device 102.

  In addition, since each smart device 101 notifies each control device 102 of an instance code set to each control device 102, each control device 102 that has designated element information can be managed separately. Even if the information related to the control device 102 such as the identification information of the control device 102 is changed after designating the element information, the element information designated by the control device 102 can be accurately specified.

  Also, in the smart meter 101 in the information distribution system 201 according to the first embodiment of the present invention, when the providing unit 15 receives an information request from the control device 102, the instance code and ID stored in the storage unit 12 , The element information corresponding to the instance code indicated by the information request is specified, and the specified element information is provided to the control apparatus 102.

  With such a configuration, even when the control device 102 makes an information request to the smart meter 101 after the control device 102 specifies element information to the smart meter 101, the control device 102 The specified element information can be accurately identified and provided.

  In the smart meter 101 in the information distribution system 201 according to the first embodiment of the present invention, the instance includes a plurality of time-series element information, and new element information is created regularly or irregularly. .

  With such a configuration, information updated with the passage of time can be correctly provided to the device.

(Second Embodiment)
In the information distribution system 201 according to the first embodiment described above, the smart meter 101 provides information to a plurality of control devices 102. In contrast, in the information distribution system 201 according to the second embodiment of the present invention, the electric device 161 provides information to the plurality of control devices 102.

[Configuration and basic operation]
(Configuration of the entire information distribution system)
Referring to FIG. 1 again, in the information distribution system 201 according to the second embodiment of the present invention, the electric device (information distribution apparatus) 161 is element information (hereinafter referred to as “property information”) regarding its own operation. ) To the control device 102. And the control apparatus 102 controls the electric equipment 161 which is the transmission origin of the said property information using the property information received from the electric equipment 161. FIG.

  For example, when the electric device 161 is an air conditioner, the electric device 161 transmits information indicating the current set temperature to the control device 102. When the control device 102 receives information indicating the current set temperature from the electric device 161, the control device 102 comprehensively determines the power consumption, the current temperature in the house, and the like to increase the set temperature of the electric device 161. Take control.

  Note that there may be a difference in control items that can be performed on the electric device 161 between the control device 102A and the control device 102B.

  For example, when the electric device 161 is an air conditioner, the control device 102A switches the power on / off, sets the temperature, controls the amount of current consumption, switches between the normal mode and the rapid mode, and On the other hand, the control device 102B is configured to be able to switch on / off the power source and set only the temperature for the electric device 161. May be.

(Configuration of electrical equipment)
FIG. 6 is a diagram showing a configuration of an electrical device in the information distribution system according to the second embodiment of the present invention.

  Referring to FIG. 6, electrical device 161 includes an acquisition unit 21, a storage unit 22, a setting unit 23, a notification unit 24, a providing unit 25, and a receiving unit 26.

  For example, when the electric device 161 is an air conditioner, the acquisition unit 21 receives a temperature setting value or a wind direction setting value from a remote controller operated by the user, and causes the electric device 161 to operate according to the received setting value. To control. In addition, the acquisition unit 21 outputs setting values and the like included in the signal received from the remote controller to the storage unit 22 as property information, and the storage unit 22 stores the property information.

  For example, the storage unit 22 stores a plurality of time-series property information, that is, “property information three hours ago”, “property information two hours ago”, “property information one hour ago”, and “current property information”. Remember.

  Note that “property information three hours ago”, “property information two hours ago”, “property information one hour ago”, and “current property information” each include detailed information. For example, when the electric device 161 is an air conditioner, each property information includes information indicating power on / off, information indicating a set temperature, information indicating a measured value of current consumption, and whether the operation is performed in a normal mode. Or the information which shows whether it is operating in rapid mode and the information which shows a wind direction are contained as detailed information.

  The setting unit 23 assigns an ID to each property information stored in the storage unit 22. For example, the setting unit 23 assigns “ID1” to “property information three hours ago”, “ID2” to “property information two hours ago”, and “ID3” to “property information one hour ago”. ", And" ID4 "is assigned to" Current Property Information ".

  In addition, the setting unit 23 uses the plurality of property information stored in the storage unit 22 to generate an instance including one or a plurality of property information for each of the control devices 102A and 102B, and adds an instance to each generated instance. Set the code.

  FIG. 7 is a diagram illustrating a specific example of an instance generated by the setting unit illustrated in FIG.

  That is, as illustrated in FIG. 7A, the setting unit 23 generates an instance for the control apparatus 102A and sets the instance code “01” for the instance. Further, as illustrated in FIG. 7B, the setting unit 23 generates an instance for the control device 102B and sets the instance code “02” for the instance.

  For example, the setting unit 23 is given “Property information three hours ago” and “ID2” with “ID1” as the type of element information, for both “Instance01” and “Instance02”. Instances are generated so as to include “property information two hours ago”, “property information one hour ago” assigned “ID3”, and “current property information” assigned “ID4”.

  Note that the setting unit 23 generates “instance 01” and “instance 02” according to the control items that the control devices 102A and 102B can respectively perform on the electric device 161. The detailed information included in the element information in and the detailed information included in the element information in “Instance 02” may be different information.

  For example, when the electric device 161 is an air conditioner, the setting unit 23 displays “operation state” that is information indicating power on / off, “temperature” that is information indicating set temperature, and information that indicates a measured value of current consumption. Detailed information includes “current state”, “operation mode” which is information indicating whether the current mode is operating in the normal mode or rapid mode, and “wind direction” which is information indicating the wind direction. An “instance 01” can be created to be included. Further, the setting unit 23 can generate “instance 02” so that only “operation information” and “temperature” are included as detailed information.

  Referring to FIG. 6 again, the notification unit 24 notifies the corresponding control device 102 of the instance code set by the setting unit 23.

  When receiving the instance code and ID notified from the control device 102, the receiving unit 26 outputs the received instance code and ID to the storage unit 22. The storage unit 22 receives the instance code and ID received from the receiving unit 26. Store it in association.

  The providing unit 25 receives an information request from the control device 102. When receiving the information request, the providing unit 25 uses the storage content stored in the storage unit 22, that is, the control device 102 that has transmitted the information request using the instance code and ID notified from the control device 102. Specify the property information to request. Then, the providing unit 25 transmits the specified property information to the control device 102.

  Specifically, the providing unit 25, when the instance code “01” and “ID1” are stored in the storage unit 22 as the instance code and ID notified from the control device 102A, the instance code from the control device 102A. When an information request including “01” is received, “instance 01” to which instance code “01” is set is identified from the generated instances.

  Then, the providing unit 25 specifies information of “ID1” included in the specified “instance 01”, for example, “property information three hours ago” as property information to be transmitted. Then, the providing unit 25 includes detailed information included in the identified property information, specifically, “operation state”, “temperature”, “current state”, “operation mode”, and “operation mode” of its own electrical device 161 three hours ago. “Wind direction” is transmitted to the control device 102A.

  Then, the providing unit 25 specifies the information of “ID2” included in the specified “instance 02”, for example, “property information two hours ago” as property information to be transmitted. Then, the providing unit 25 transmits detailed information included in the specified property information, specifically, “operation state” and “temperature” of its own electric device 161 two hours ago to the control device 102B.

[Operation]
Next, the operation of the information distribution system according to the second embodiment of the present invention will be described with reference to the drawings.

  FIG. 8 is a sequence diagram defining an information distribution procedure by the information distribution system according to the second embodiment of the present invention.

  Each device in the information distribution system 201 includes a computer, and an arithmetic processing unit such as a CPU in the computer reads and executes a program including a part or all of each step in the following sequence diagram from a memory (not shown). Each of the programs of the plurality of apparatuses can be installed from the outside. The programs of the plurality of apparatuses are distributed while being stored in a recording medium.

  Referring to FIG. 8, first, electrical device 161 stores property information indicating its own operating state for each time period, for example (step S41). And the electric equipment 161 gives ID to each property information (step S42).

  Since the operation from step S43 to step S58 is the same as the operation from step S13 to step S28 shown in FIG. 5 except for the operating subject, detailed description thereof will not be repeated here.

  Note that the electrical device 161 is included in the element information in “Instance 01” according to the control items that the control devices 102A and 102B can respectively perform in the generation of instances in Step S45 and Step S49. The detailed information and the detailed information included in the element information in “Instance 02” can be different information.

  Specifically, the electric device 161 includes the IP address and device type information of the control device 102A, and the control device 102A switches power on / off, sets temperature, controls current consumption, and normal mode. Are stored in association with each other that it is possible to switch between the rapid mode and the rapid mode and to set the wind direction. In this case, the electric device 161 includes “operation state”, “temperature”, “current state”, “operation mode”, and “wind direction” as detailed information in the “instance 01” for the control device 102A in step S45. be able to.

  In addition, the electrical device 161 has the IP address and device type information of the control device 102B, and that the control device 102B can perform power on / off switching and temperature setting for itself. Assume that they are stored in association. In this case, the electric device 161 can include “operation state” and “temperature” as detailed information in the “instance 02” for the control apparatus 102B in step S49.

  Next, when the control device 102A notifies the electric device 161 of the instance code “01” set to itself and the information request (step S59), the electric device 161 uses the stored contents stored in step S54. , “ID1” associated with the instance code “01”, for example, “property information three hours ago” included in “instance 01” is specified as element information to be transmitted.

  Then, the electric device 161 includes detailed information included in the identified element information, for example, “operation state”, “temperature”, “current state”, “operation mode”, and “wind direction” of its own electric device 161 three hours ago. Is transmitted to the control device 102A as an information request response (step S60).

  Next, when the control device 102B notifies the instance code “02” set for itself and the information request to the electric device 161 (step S61), the electric device 161 uses the stored contents stored in step S58. “ID2” associated with the instance code “02”, for example, “property information two hours ago” included in “instance 02” is specified as element information to be transmitted.

  Then, the electric device 161 transmits detailed information included in the identified element information, for example, “operation state” and “temperature” of the electric device 161 of two hours ago to the control device 102B as an information request response ( Step S62).

  In the example described above, the case where the electric device 161 transmits the property information to the control devices 102A and 102B has been described. However, the information transmitted from the electric device 161 may be other types of information.

  For example, the electrical device 161 may transmit information on the entire instance to the control device 102. Specifically, the electrical device 161 generates “instance 01” for the control device 102A and generates “instance 02” for the control device 102B.

  In this case, when the electrical device 161 receives the designation of the instance code “01” from the control device 102A, the electrical device 161 identifies “instance 01” and identifies the entire identified “instance 01”, for example, “operation state” three hours ago, “Temperature”, “Current state”, “Operation mode” and “Wind light” (hereinafter also referred to as “Five detailed information”), five detailed information two hours ago, and five details one hour ago Information and the current five detailed information can be transmitted to the control apparatus 102A.

  In the above case, when the electrical device 161 receives the designation of the instance code “02” from the control device 102B, the electrical device 161 identifies “instance 02”, and the entire “instance 02” identified, for example, “operation” for 3 hours before "Status" and "temperature" (hereinafter also referred to as "two detailed information"), two detailed information two hours ago, two detailed information one hour ago, and two detailed information at present Can be transmitted to the control device 102B.

  In the above-described example, the case where the information request is notified by the control device 102 after the ID notification is performed by the control device 102 has been described. However, the control device 102 does not include the information request in the ID notification. Notifications can be included. When receiving the notification of the ID including the notification of the information request from the control device 102, the electric device 161 transmits the element information corresponding to the notified ID to the control device 102.

  As described above, in the electric device 161 in the information distribution system 201 according to the second exemplary embodiment of the present invention, the setting unit 23 displays the instance code of the instance that the control device 102 should notify the electric device 161. Set every 102. Further, the notification unit 24 notifies the corresponding control device 102 of the instance code set by the setting unit 23. In addition, the storage unit 22 stores the instance code notified from the control device 102 for each control device 102. Further, the providing unit 25 identifies an instance requested by the control device 102 based on the instance code stored in the storage unit 22 and provides the identified instance to the control device 102.

  As described above, the configuration in which the instance code of the instance used when the control device 102 designates an instance is set for each control device 102 allows the instance designated by the control device 102 to be accurately identified from among a plurality of instances. can do. That is, it is possible to prevent an instance different from the instance designated by each control device 102 from being provided to each control device 102.

  Further, each control device 102 can be managed separately by notifying each control device 102 of the instance code set in each control device 102 by the electric device 161, so that a certain control device 102 Even when the information related to the control device 102 such as the identification information of the control device 102 is changed after the instance is specified, the instance specified by the control device 102 can be accurately specified.

  In the electric appliance 161 in the information distribution system 201 according to the second embodiment of the present invention, when the providing unit 25 receives an information request from the control device 102, the providing unit 25 refers to the instance code stored in the storage unit 22. By doing so, the instance corresponding to the instance code indicated by the information request is specified, and the specified instance is provided to the control device 102.

  With such a configuration, even when the control device 102 makes an information request to the electrical device 161 after the control device 102 designates an instance to the electrical device 161, the control device 102 designates it. Can be identified and provided accurately.

  Then, the providing unit 25 specifies the information of “ID2” included in the specified “instance 02”, for example, “contract power consumption information of last month” as property information to be transmitted. Then, the providing unit 34 transmits detailed information included in the identified element information, for example, “last month contract power consumption information at home B” to the control device 102B.

[Operation]
Next, the operation of the information distribution system according to the third embodiment of the present invention will be described with reference to the drawings.

  FIG. 12 is a sequence diagram defining an information acquisition procedure for device management by the information distribution system according to the third embodiment of the present invention.

  Each device in the information distribution system 201 includes a computer, and an arithmetic processing unit such as a CPU in the computer reads and executes a program including a part or all of each step in the following sequence diagram from a memory (not shown). Each of the programs of the plurality of apparatuses can be installed from the outside. The programs of the plurality of apparatuses are distributed while being stored in a recording medium.

  Referring to FIG. 12, first, management server 151 assigns an ID to each piece of element information that is, for example, monthly contracted power consumption information (step S71).

  Since the operations from step S72 to step S87 are the same as the operations from step S13 to step S28 shown in FIG. 5 except for the operating subject, detailed description thereof will not be repeated here.

  The management server 151 generates different information for the detailed information included in the element information in “Instance 01” and the detailed information included in the element information in “Instance 02” in the generation of instances in Step S74 and Step S78. be able to.

  Specifically, it is assumed that the management server 151 stores the IP address and device type information of the control device 102A in association with the home where the control device 102A is installed being A home. In this case, in step S74, the management server 151 includes “instance 01” for the control device 102A as detailed information “contract power consumption information for the last month at home A” and “contract power consumption for the last month at home A”. "Information" and "contract power consumption information of this month at home A" can be included.

  Further, specifically, the management server 151 stores the IP address and device type information of the control device 102B in association with the home where the control device 102B is installed being B home. . In this case, in step S78, the management server 151 includes “instance 02” for the control apparatus 102B as detailed information “contract power consumption information of last month at B house” and “contract power consumption of last month at B house”. "Information" and "contract power consumption information of this month at house B" can be included.

  Next, when the control device 102A notifies the management server 151 of the instance code “01” set for itself and the information request (step S88), the management server 151 uses the stored contents stored in step S83. Then, “ID1” associated with the instance code “01”, for example “contract power consumption information of last month” included in “instance 01”, is specified as element information to be transmitted.

  Then, the management server 151 transmits detailed information included in the identified element information, for example, “contract power consumption information of last month at A home” to the control device 102A as an information request response (step S89).

  Next, when the control device 102B notifies the management server 151 of the instance code “02” set for itself and the information request (step S90), the management server 151 uses the stored contents stored in step S87. , “ID2” associated with the instance code “02”, for example “contract power consumption information of last month” included in “instance 02”, is specified as element information to be transmitted.

  Then, the management server 151 transmits detailed information included in the identified element information, for example, “contract power consumption information of last month at home B” to the control device 102B as an information request response (step S91).

  In the example described above, the case where the management server 151 transmits the contract power consumption information to the control devices 102A and 102B has been described. However, the information transmitted from the management server 151 may be other types of information. .

  For example, the management server 151 may transmit information on the entire instance to the control device 102. Specifically, it is assumed that the management server 151 generates “instance 01” for the control apparatus 102A and generates “instance 02” for the control apparatus 102B.

  In this case, when the management server 151 receives the designation of the instance code “01” from the control device 102A, the management server 151 identifies “instance 01”. It is possible to transmit the amount information, the contract power consumption information of last month at the A home, and the contract power consumption information of the current month at the A home to the control device 102A.

  In the above case, when the management server 151 receives the designation of the instance code “02” from the control device 102B, the management server 151 identifies “instance 02”, and identifies the entire identified “instance 02”, for example, the last month at B house. It is possible to transmit the contract power consumption information, the contract power consumption information of last month at the B home, and the contract power consumption information of the current month at the B home to the control device 102B.

  In the above-described example, the case where the information request is notified by the control device 102 after the ID notification is performed by the control device 102 has been described. However, the control device 102 does not include the information request in the ID notification. Notifications can be included. When the management server 151 receives a notification of an ID including a notification of an information request from the control device 102, the management server 151 transmits element information corresponding to the notified ID to the control device 102.

  As described above, in the management server 151 in the information distribution system 201 according to the third exemplary embodiment of the present invention, the setting unit 32 displays the instance code of the instance that the control device 102 should notify the management server 151. Set every 102. The notification unit 33 notifies the corresponding control device 102 of the instance code set by the setting unit 32. In addition, the storage unit 31 stores the instance code notified from the control device 102 for each control device 102. Further, the providing unit 34 identifies an instance requested by the control device 102 based on the instance code stored in the storage unit 31 and provides the identified instance to the control device 102.

  As described above, the configuration in which the instance code of the instance used when the control device 102 designates an instance is set for each control device 102 allows the instance designated by the control device 102 to be accurately identified from among a plurality of instances. can do. That is, it is possible to prevent an instance different from the instance designated by each control device 102 from being provided to each control device 102.

  In addition, since the management server 151 notifies each control device 102 of the instance code set to each control device 102, each control device 102 that has designated an instance can be managed separately. Even when the information related to the control device 102 such as the identification information of the control device 102 is changed after the instance is specified, the instance specified by the control device 102 can be accurately specified.

  Further, in the management server 151 in the information distribution system 201 according to the third embodiment of the present invention, when the providing unit 34 receives an information request from the control device 102, the providing unit 34 refers to the instance code stored in the storage unit 31. By doing so, the instance corresponding to the instance code indicated by the information request is specified, and the specified instance is provided to the control device 102.

  With such a configuration, even when the control device 102 makes an information request to the management server 151 after the control device 102 designates an instance to the management server 151, the control device 102 designates it. Can be identified and provided accurately.

(Fourth embodiment)

To do.

  On the other hand, in the information distribution system 201 according to the fourth embodiment of the present invention, the ID notified from the device and the identification information of the device are stored in association with each other.

  The information distribution system 201 according to the fourth embodiment of the present invention is the same as the information distribution system 201 according to the first embodiment of the present invention described above except for the operation of each unit in the smart meter 101. is there.

(Configuration of smart meter)
Referring to FIG. 2 again, the smart meter 101 according to the fourth embodiment of the present invention is similar to the smart meter 101 according to the first embodiment of the present invention in that the acquisition unit 11 and the storage unit 12 A setting unit 13, a notification unit 14, a providing unit 15, and a receiving unit 16. Here, differences from the smart meter 101 according to the first embodiment of the present invention will be mainly described.

  The setting unit 13 uses the distribution information stored in the storage unit 12 to generate an instance including part or all of the element information included in the distribution information, and sets an instance code for the generated instance. At this time, the setting unit 13 sets a common instance code for the control devices 102A and 102B without setting an instance code for each of the control devices 102A and 102B.

  For example, the setting unit 13 generates a common instance for the control devices 102A and 102B, and sets the instance code “0X” to the generated instance. In this case, when specifying the element information included in the instance, the control device 102A notifies the smart meter 101 of the instance code “0X” and the ID specifying the arbitrary element information included in “instance 0X”. To do. Further, when designating element information included in the instance, the control device 102B notifies the smart meter 101 of the instance code “0X” and an ID designating arbitrary element information included in “instance 0X”. .

  When receiving the instance code and the ID from the control device 102, the receiving unit 16 acquires the identification information of the device that has notified the ID. This identification information is, for example, the device IP address and device type information. Then, the reception unit 16 outputs the acquired IP address and device type information and the notified ID to the storage unit 12.

  The storage unit 12 stores the IP address received from the receiving unit 16, the device type information, and the ID in association with each other.

  FIG. 13 is a diagram showing a specific example of the correspondence relationship between the IP address, device type information, and ID stored in the storage unit of the smart meter in the information distribution system according to the fourth embodiment of the present invention. is there.

  Referring to FIG. 13, for example, when “ID1” is notified from control device 102 </ b> A, receiving unit 16 acquires and acquires the IP address and device type information of control device 102 </ b> A that has notified “ID1”. The control unit 102A outputs the IP address and device type information to the storage unit 12. Then, the storage unit 12 stores the IP address of the control device 102A, the device type information of the control device 102A, and “ID1” notified by the control device 102A in association with each other.

  Further, for example, when “ID2” is notified from the control device 102B, the receiving unit 16 acquires the IP address and device type information of the control device 102B that has notified “ID2”, and acquires the acquired control device 102B. The IP address and device type information are output to the storage unit 12. Then, the storage unit 12 stores the IP address of the control device 102B, the device type information of the control device 102B, and “ID2” notified by the control device 102B in association with each other.

  Referring to FIG. 2 again, upon receiving an information request from control device 102, providing unit 15 acquires the IP address and device type information of the device that is the source of the information request. Then, the providing unit 15 uses the storage content stored in the storage unit 12, that is, the control device 102 that has transmitted the information request using the IP address of the control device 102, the device type information of the control device 102, and the ID. Specifies the element information of the instance requested by. Then, the providing unit 15 transmits the identified element information to the control device 102.

  Specifically, the providing unit 15 determines the information request when the IP address of the control device 102A, the device type information of the control device 102A, and “ID1” are stored in the storage unit 12 in association with each other. When the IP address and device type information of the device that is the transmission source are the same as the IP address and device type information of the control device 102A, the element information to which "ID1" is assigned is specified, and the specified element information is requested for information Is transmitted to the device that is the transmission source, that is, the control device 102A.

  Further, the providing unit 15 is the transmission source of the information request when the IP address of the control device 102B, the device type information of the control device 102B, and “ID2” are stored in the storage unit 12 in association with each other. When the IP address and device type information of a certain device are the same as the IP address and device type information of the control apparatus 102B, the element information to which “ID2” is assigned is specified, and the specified element information is sent from the source of the information request To the device, that is, the control device 102B.

  Referring to FIG. 14, first, smart meter 101 receives distribution information from management server 151 (step S101). Here, the smart meter 101 receives from the management server 151 distribution information including the electricity price information of the current day, the next day, and the next day as element information.

  Next, the smart meter 101 assigns an ID to each element information included in the distribution information received from the management server 151 (step S102).

  Next, the smart meter 101 generates a common instance for the control apparatuses 102A and 102B using the distribution information, and sets, for example, an instance code “0X” to the generated instance (step S103).

  Next, when the control device 102A transmits a device information inquiry to the smart meter 101 (step S104), the smart meter 101 receives the device information inquiry, and a device type code and an instance code assigned to itself. “0X” is transmitted to the control apparatus 102A as a device information response (step S105).

  Next, it is assumed that there is a device information inquiry interruption by the control device 102B. That is, when the control device 102B transmits a device information inquiry to the smart meter 101 (step S106), the smart meter 101 receives the device information inquiry, and the device type code and instance code “ 0X ", that is, the same information as the information transmitted in step S105 is transmitted to the control apparatus 102B as a device information response (step S107).

  Next, when the control device 102A transmits to the smart meter 101 an ID notification request for inquiring the type of element information included in “instance 0X” corresponding to the instance code notified from the smart meter 101 ( In step S108), the smart meter 101 receives this ID notification request, and transmits the type of element information included in “instance 0X” as an ID notification response.

  Here, “instance 0X” is assigned “ID1” with “electric charge information on the day”, “ID2” with “electric charge information on the next day”, and “ID3” with “ID3”. It is assumed that “the electricity bill information for the next day” is included. In this case, in the smart meter 101, the types of element information corresponding to “ID1” to “ID3” are “electricity information on the current day”, “electricity information on the next day”, and “electricity information on the next day”, respectively. A list indicating this is transmitted to the control apparatus 102A as an ID notification response (step S109).

  Next, the control device 102A receives the ID notification response from the smart meter 101, specifies the ID of any element information from the element information included in “instance 0X”, and includes the instance code and the specified information. ID is notified. For example, the control information 102A notifies the instance code “0X” and “ID1” when it is desired to acquire “electric charge information on that day” (step S110).

  Next, the smart meter 101 performs message analysis on the received notification, thereby acquiring the IP address of the device that has made the notification and the device type information of the device that has made the notification (step S111). .

  Then, the smart meter 101 stores the acquired IP address, device type information, the notified ID, that is, the IP address of the control device 102A, the device type information of the control device 102A, and “ID1” in association with each other. (Step S112).

  Next, when the control device 102B transmits to the smart meter 101 an ID notification request for inquiring about the type of element information included in “Instance 0X” corresponding to the instance code notified from the smart meter 101 ( In step S113), the smart meter 101 receives the ID notification request and transmits the type of element information included in “instance 0X” as an ID notification response (step S114).

  Next, the control device 102B receives an ID notification response similar to that transmitted from the smart meter 101 to the control device 102A, and assigns the ID of any element information from the element information included in the “instance 0X”. It designates and notifies the instance code and the ID which is the designation information. For example, the control information 102B notifies the instance code “0X” and “ID2” when it is desired to acquire “the electricity bill information for the next day” (step S115).

  Next, the smart meter 101 performs message analysis on the received notification, thereby acquiring the IP address of the device that has made the notification and the device type information of the device that has made the notification (step S116). .

  Then, the smart meter 101 stores the acquired IP address, device type information, the notified ID, that is, the IP address of the control device 102B, the device type information of the control device 102B, and “ID2” in association with each other. (Step S117).

  Next, when the control device 102A notifies the smart meter 101 of the information request (step S118), the smart meter 101 performs a message analysis on the information request, so that the device that is the transmission source of the information request is sent. The IP address and device type information of the device that is the transmission source, that is, the IP address and device type information of the control device 102A are acquired.

  The smart meter 101 uses the stored content stored in step S112 to transmit “ID1” associated with the IP address and device type information of the control device 102A, for example, “electricity information on the day”. It specifies as information (step S119). Then, the smart meter 101 transmits the identified element information as an information request response to the control device 102A (step S120).

  Next, when the control device 102B notifies the information request to the smart meter 101 (step S121), the smart meter 101 performs a message analysis on the information request, thereby identifying the device that is the transmission source of the information request. The IP address and device type information of the device that is the transmission source, that is, the IP address and device type information of the control device 102B are acquired.

The IP address and device type information are stored for each IP address and device type information. The providing unit 25 identifies the element information of the instance requested by the control device 102 based on the ID, IP address, and device type information stored in the storage unit 22, and sends the identified element information to the control device 102. provide.

  With such a configuration, by confirming the ID corresponding to the IP address and device type information of the control device 102, the element information specified by the control device 102 is any element information of the plurality of element information in the instance. It is possible to accurately identify whether or not there is. That is, it is possible to prevent element information different from element information designated by each control device 102 from being provided to each control device 102.

  Further, for example, since it is not necessary to set new information for each control device 102, an information distribution system 201 with a simple configuration and processing can be realized.

  Moreover, in the electrical equipment 161 in the information distribution system 201 according to the fifth exemplary embodiment of the present invention, when the providing unit 25 receives an information request from the control device 102, the ID stored in the storage unit 22, and the control By referring to the IP address of the device 102 and the device type information of the control device 102, element information corresponding to the control device 102 that is the transmission source of the information request is specified, and the specified element information is provided to the control device 102. .

  With this configuration, even when the control device 102 makes an information request to the electric device 161 after the control device 102 specifies element information for the electric device 161, the control device 102 The specified element information can be accurately identified and provided.

(Modification)
In the information distribution system 201 according to the fifth embodiment of the present invention described above, the electric device 161 generates a common instance for the control devices 102A and 102B. However, it is not limited to such a form, The electric equipment 161 may produce | generate a separate instance for every control apparatus 102A, 102B.

  Specifically, when the electrical device 161 first receives a device information inquiry from the control device 102A, it acquires the IP address of the device that is the transmission source of the device information inquiry and the device type information of the device that is the transmission source. To do.

  Then, the electrical device 161 uses the property information stored in itself to generate an instance for the device having the acquired IP address and device type information, and sets an instance code such as “0X” in the generated instance. To do. Then, the electric device 161 transmits the device type code assigned to itself and the instance code “0X” to the control device 102A as a device information response.

  In addition, the electric device 161 stores the instance generated for the control device 102A in association with the IP address and device type information of the control device 102A.

  Next, when receiving the device information inquiry from the control device 102B, the electric device 161 acquires the IP address of the device that is the transmission source of the device information inquiry and the device type information of the device that is the transmission source.

  Then, the electrical device 161 uses the property information stored in itself to generate an instance for the device having the acquired IP address and device type information, and sets an instance code such as “0X” in the generated instance. To do. Then, the electrical device 161 transmits the device type code assigned to itself and the instance code “0X” to the control device 102B as a device information response.

  In addition, the electrical device 161 stores the instance generated for the control device 102B in association with the IP address and device type information of the control device 102B.

  Here, the electric device 161 includes the IP address of the control device 102A, the device type information of the control device 102A, and items of control that the control device 102A can perform on itself, such as “operation state” and “temperature”. Assume that “current state”, “operation mode”, and “wind direction” are stored in advance in association with each other. In this case, the electric device 161 can include “operation state”, “temperature”, “current state”, “operation mode”, and “wind direction” as detailed information in the instance for the control device 102A.

  In addition, the electric device 161 includes an IP address of the control device 102B, device type information of the control device 102B, and control items that the control device 102B can perform on itself, such as “operation state” and “temperature”. Are stored in advance in association with each other. In this case, the electric device 161 can include “operation state” and “temperature” as detailed information in the instance for the control device 102B.

  Next, upon receiving the designation of the ID of any element information included in the instance from the control device 102, the electric device 161 obtains the IP address and device type information of the designated device, and obtains the obtained IP address and The device type information and the notified ID are stored in association with each other.

  For example, when receiving the notification of “ID1” from the control device 102A, the electrical device 161 associates the IP address of the control device 102A, the device type information of the control device 102A, and “ID1” notified from the control device 102A. Then remember. In addition, when receiving the notification of “ID2” from the control device 102B, the electric device 161 associates the IP address of the control device 102B, the device type information of the control device 102B, and “ID2” notified from the control device 102B. Then remember.

  Next, when receiving an information request from the control device 102, the electric device 161 acquires the IP address of the device that is the transmission source of the information request and the device type information of the device that is the transmission source. Then, the electrical device 161 identifies the instance for the device that is the transmission source of the information request, using the correspondence between the stored contents, that is, the IP address and device type information, and the instance.

  Furthermore, using the correspondence between the IP address and the device type information and the ID, the electric device 161 identifies the ID corresponding to the IP address and the device type information of the device that is the transmission source of the information request. Then, the electric device 161 identifies information to be transmitted to the control device 102 based on the identified instance and ID, and transmits the identified information to the control device 102.

  For example, when receiving an information request from the control device 102A, the electrical device 161 identifies an instance for the control device 102A based on the IP address and device type information of the control device 102A included in the information request. Furthermore, based on the IP address of the control device 102A and the device type information included in the information request, the electric device 161 specifies “ID1” as an ID for designating element information.

  Then, the electric device 161 includes the “operation state”, “temperature”, “current state”, “operation mode” included in the detailed information of “ID1” in the instance for the control device 102A, for example, “property information three hours ago”. And “wind direction” are transmitted to the control apparatus 102A as information request responses.

  Further, for example, when receiving an information request from the control device 102B, the electrical device 161 identifies an instance for the control device 102B based on the IP address and device type information of the control device 102B included in the information request. Furthermore, based on the IP address of the control device 102B and the device type information included in the information request, the electric device 161 identifies “ID2” as an ID for designating element information.

  Note that the electric device 161 may transmit information on the entire instance to the control device 102. Specifically, it is assumed that the electric device 161 generates “instance 0X” for the control device 102A and “instance 0X” for the control device 102B.

  In this case, when the electrical device 161 receives the designation of the instance code “0X” without receiving the designation of the ID from the control device 102A, the electrical device 161 identifies “instance 0X” for the control device 102A, and identifies the identified control device 102A. Information on the entire “instance 0X”, for example, “operation state”, “temperature”, “current state”, “operation mode” and “wind light” (hereinafter also referred to as “five detailed information”) ), Five pieces of detailed information two hours ago, five pieces of detailed information one hour ago, and five pieces of detailed information at the present time can be transmitted to the control device 102A.

  In the above case, when the electrical device 161 receives the designation of the instance code “0X” without receiving the designation of the ID from the control device 102B, the electrical device 161 identifies and identifies the “instance 0X” for the control device 102B. Information on the entire “instance 0X” for the control device 102B, for example, “operation state” and “temperature” (hereinafter also referred to as “two detailed information”) three hours ago, and two detailed information two hours ago In addition, two pieces of detailed information one hour ago and two pieces of detailed information at the present time can be transmitted to the control apparatus 102B.

  In the above-described example, the case where the information request is notified by the control device 102 after the ID notification is performed by the control device 102 has been described. However, the control device 102 does not include the information request in the ID notification. Notifications can be included. When receiving the notification of the ID including the notification of the information request from the control device 102, the electric device 161 transmits the element information corresponding to the notified ID to the control device 102.

  As described above, in the electrical device 161 in the modification of the information distribution system 201 according to the fifth exemplary embodiment of the present invention, the storage unit 22 has a correspondence relationship between the instance, the IP address of the control device 102, and the device type information. Remember. Further, the providing unit 25 identifies the instance requested by the control device 102 based on the correspondence relationship stored in the storage unit 22 and provides the identified instance to the control device 102.

  With such a configuration, by confirming the instance corresponding to the IP address and device type information of the control device 102, the instance specified by the control device 102 can be accurately identified from among a plurality of instances. That is, it is possible to prevent an instance different from the instance designated by each control device 102 from being provided to each control device 102.

  Further, for example, since it is not necessary to set new information for each control device 102, an information distribution system 201 with a simple configuration and processing can be realized.

  Moreover, in the electric equipment 161 in the modification of the information distribution system 201 according to the fifth exemplary embodiment of the present invention, when the providing unit 25 receives an information request from the control device 102, the correspondence stored in the storage unit 22 By referring to the relationship, that is, the correspondence between the instance and the IP address and device type information of the control device 102, the control device that is the transmission source of the information request based on the IP address and the device type information included in the information request The instance corresponding to 102 is specified, and the specified instance is provided to the control apparatus 102.

  With such a configuration, even when the control device 102 makes an information request to the electric device 161 after the control device 102 specifies information included in the instance to the electric device 161, the control device 102 The instance specified by the device 102 can be accurately identified and provided.

  Specifically, the providing unit 34 associates the IP address of the control device 102A, the device type information of the control device 102A, “ID1”, and “contract usage energy information at home A” which is detailed information. If the IP address and device type information of the device that is the transmission source of the information request are the same as the IP address and device type information of the control device 102A, “ID1” is stored. The assigned element information is specified, and “contract usage energy information at home A” included in the specified element information is transmitted to the device that is the transmission source of the information request, that is, the control apparatus 102A.

  Further, the providing unit 34 stores the IP address of the control device 102B, the device type information of the control device 102B, “ID2”, and the detailed information “contract usage energy information at home B”. If the IP address and device type information of the device that is the transmission source of the information request are the same as the IP address and device type information of the control device 102B, “ID2” is assigned. Element information is specified, and “contract usage energy information at home B” included in the specified element information is transmitted to the device that is the transmission source of the information request, that is, the control apparatus 102A.

[Operation]
Next, the operation of the information distribution system according to the sixth embodiment of the present invention will be described with reference to the drawings.

  FIG. 18 is a sequence diagram defining an information distribution procedure by the information distribution system according to the sixth embodiment of the present invention.

  Each device in the information distribution system 201 includes a computer, and an arithmetic processing unit such as a CPU in the computer reads and executes a program including a part or all of each step in the following sequence diagram from a memory (not shown). Each of the programs of the plurality of apparatuses can be installed from the outside. The programs of the plurality of apparatuses are distributed while being stored in a recording medium.

  Referring to FIG. 18, first, management server 151 assigns an ID to each element information that is, for example, monthly contracted power consumption information (step S161).

  Since the operations from step S162 to step S176 are the same as the operations from step S103 to step S117 shown in FIG. 14 except for the operating subject, detailed description thereof will not be repeated here.

  In addition to the IP address of the control device 102, the device type information of the control device 102, and the ID notified by the control device 102, the management server 151 is further installed in step S171 and step S176. The detailed information indicating the contracted power consumption information in the household is stored in association with each other.

  Next, when the control device 102A notifies the management server 151 of the information request (step S1177), the management server 151 analyzes the message with respect to the information request, and thereby the device that is the transmission source of the information request. The IP address and device type information of the device that is the transmission source, that is, the IP address and device type information of the control device 102A are acquired.

  Then, the management server 151 specifies “ID1” associated with the IP address and device type information of the control device 102A and the detailed information using the storage contents stored in step S171 (step S178). Then, the management server 151 uses the identified “ID1” and the detailed information, for example, “contract usage power amount information at home A” included in “contract usage power amount information in last month” to which “ID1” is assigned. Is transmitted to the control device 102A as an information request response (step S179).

  Next, when the control device 102B notifies the management server 151 of the information request (step S180), the management server 151 performs a message analysis on the information request, and thereby the device that is the transmission source of the information request. The IP address and device type information of the device that is the transmission source, that is, the IP address and device type information of the control device 102B are acquired.

  Then, the management server 151 specifies “ID2” associated with the IP address and device type information of the control apparatus 102B and the detailed information using the storage contents stored in step S176 (step S181). Then, the management server 151 uses the identified “ID2” and the detailed information, for example, “contracted power consumption information at home B” included in “contracted power consumption information in last month” assigned “ID2”, for example. Is transmitted to the control apparatus 102B as an information request response (step S182).

  In the example described above, the case where the management server 151 transmits the contract power consumption information to the control devices 102A and 102B has been described. However, the information transmitted from the management server 151 may be other types of information. .

  As described above, in the management server 151 in the information distribution system 201 according to the sixth exemplary embodiment of the present invention, the storage unit 31 specifies the element information notified from the control device 102 and the control device 102. The IP address and device type information are stored for each IP address and device type information. The providing unit 34 specifies the element information of the instance requested by the control device 102 based on the ID, the IP address, and the device type information stored in the storage unit 31, and supplies the specified element information to the control device 102. provide.

  With such a configuration, by confirming the ID corresponding to the IP address and device type information of the control device 102, the element information specified by the control device 102 is any element information of the plurality of element information in the instance. It is possible to accurately identify whether or not there is. That is, it is possible to prevent element information different from element information designated by each control device 102 from being provided to each control device 102.

  Further, for example, since it is not necessary to set new information for each control device 102, an information distribution system 201 with a simple configuration and processing can be realized.

  Also, in the management server 151 in the information distribution system 201 according to the sixth embodiment of the present invention, when the providing unit 34 receives an information request from the control device 102, the ID stored in the storage unit 31 and the control By referring to the IP address of the device 102 and the device type information of the control device 102, element information corresponding to the control device 102 that is the transmission source of the information request is specified, and the specified element information is provided to the control device 102. .

  With such a configuration, even when the control device 102 makes an information request to the management server 151 after the control device 102 specifies element information to the management server 151, the control device 102 The specified element information can be accurately identified and provided.

(Modification)
In the information distribution system 201 according to the sixth embodiment of the present invention described above, the management server 151 generates a common instance for the control devices 102A and 102B. However, the present invention is not limited to such a form, and the management server 151 may generate a separate instance for each of the control devices 102A and 102B.

  Specifically, when the management server 151 first receives a device information inquiry from the control device 102A, the management server 151 obtains the IP address of the device that is the transmission source of the device information inquiry and the device type information of the device that is the transmission source. To do.

  Then, the management server 151 generates an instance for the device having the acquired IP address and device type information using the element information stored by itself, and sets an instance code such as “0X” in the generated instance To do. Then, the management server 151 transmits the device type code assigned to itself and the instance code “0X” to the control device 102A as a device information response.

  In addition, the electric device 161 stores the instance generated for the control device 102A in association with the IP address and device type information of the control device 102A.

  Next, when receiving the device information inquiry from the control apparatus 102B, the management server 151 acquires the IP address of the device that is the transmission source of the device information inquiry and the device type information of the device that is the transmission source.

  Then, the management server 151 generates an instance for the device having the acquired IP address and device type information using the property information stored by itself, and sets an instance code such as “0X” in the generated instance. To do. Then, the electrical device 161 transmits the device type code assigned to itself and the instance code “0X” to the control device 102B as a device information response.

  In addition, the electrical device 161 stores the instance generated for the control device 102B in association with the IP address and device type information of the control device 102B.

  Here, the management server 151 stores the IP address and device type information of the control device 102A in association with the home in which the control device 102A is installed being A home. In addition, the management server 151 stores the IP address and device type information of the control device 102B in association with the home where the control device 102B is installed being the B home.

  In this case, the management server 151 includes, as detailed information, for example, “contract power consumption information of the last month at home A”, “contract power consumption information of last month at home A”, and “A "Contract power consumption information of this month at home" can be included. Also, the management server 151 provides detailed information to the instance for the control apparatus 102B as, for example, “contract power consumption information for the last month at B house”, “contract power consumption information for the last month at B house” and “B house”. "Contract usage energy information of this month".

  Next, upon receiving the designation of the ID of any element information included in the instance from the control device 102, the management server 151 obtains the IP address and device type information of the device that has performed the designation, and acquires the acquired IP address and The device type information and the notified ID are stored in association with each other.

  For example, when the management server 151 receives the notification “ID1” from the control device 102A, the management server 151 associates the IP address of the control device 102A, the device type information of the control device 102A, and “ID1” notified from the control device 102A. Then remember. When the management server 151 receives the notification “ID2” from the control device 102B, the management server 151 associates the IP address of the control device 102B, the device type information of the control device 102B, and “ID2” notified from the control device 102B. Then remember.

  Next, when receiving an information request from the control device 102, the management server 151 acquires the IP address of the device that is the transmission source of the information request and the device type information of the device that is the transmission source. Then, the management server 151 specifies the instance for the device that is the transmission source of the information request, using the correspondence between the stored contents, that is, the IP address and device type information, and the instance.

  Furthermore, the management server 151 specifies the ID corresponding to the IP address and device type information of the device that is the transmission source of the information request, using the correspondence relationship between the IP address and device type information and the ID. Then, the management server 151 identifies information to be transmitted to the control device 102 based on the identified instance and ID, and transmits the identified information to the control device 102.

  For example, upon receiving an information request from the control device 102A, the management server 151 identifies an instance for the control device 102A based on the IP address and device type information of the control device 102A included in the information request. Furthermore, the management server 151 specifies “ID1” as an ID for designating element information based on the IP address and device type information of the control device 102A included in the information request.

  Then, the management server 151 transmits detailed information of “ID1” in the instance for the control device 102A, for example, “contract power consumption information of the last month in the home A” to the control device 102A as an information request response.

  Further, for example, when receiving an information request from the control device 102B, the management server 151 specifies an instance for the control device 102B based on the IP address and device type information of the control device 102B included in the information request. Furthermore, the management server 151 identifies “ID2” as an ID for designating element information based on the IP address and device type information of the control device 102B included in the information request.

  Then, the management server 151 transmits the detailed information of “ID2” in the instance for the control device 102B, for example, “last month's contract power consumption information” in the B home to the control device 102B as an information request response.

  Note that the management server 151 may transmit information on the entire instance to the control device 102. Specifically, it is assumed that the management server 151 generates “instance 0X” for the control apparatus 102A and “instance 0X” for the control apparatus 102B.

  In this case, when the management server 151 receives the designation of the instance code “0X” without receiving the designation of the ID from the control device 102A, the management server 151 identifies “instance 0X” for the control device 102A, and identifies the identified control device 102A. Information on the entire “instance 0X” for use, for example, the contract power consumption information of the last month in the A house, the contract power consumption information of the last month in the A house, and the contract power consumption information of the current month in the A house It can be sent to device 102A.

  In the above case, when the management server 151 receives the designation of the instance code “0X” without receiving the designation of the ID from the control device 102B, the management server 151 identifies and identifies the “instance 0X” for the control device 102B. Information on the entire “instance 0X” for the control device 102B, for example, the contract power consumption information for the last month in the B house, the contract power consumption information for the last month in the B house, and the contract power consumption information for the current month in the B house Can be transmitted to the control device 102B.

  In the above-described example, the case where the information request is notified by the control device 102 after the ID notification is performed by the control device 102 has been described. Notifications can be included. When the management server 151 receives a notification of an ID including a notification of an information request from the control device 102, the management server 151 transmits element information corresponding to the notified ID to the control device 102.

  As described above, in the management server 151 in the modified example of the information delivery system 201 according to the sixth exemplary embodiment of the present invention, the storage unit 31 has a correspondence relationship between the instance, the IP address of the control device 102, and the device type information. Remember. In addition, the providing unit 34 identifies the instance requested by the control device 102 based on the correspondence relationship stored in the storage unit 31, and provides the identified instance to the control device 102.

  With such a configuration, by confirming the instance corresponding to the IP address and device type information of the control device 102, the instance specified by the control device 102 can be accurately identified from among a plurality of instances. That is, it is possible to prevent an instance different from the instance designated by each control device 102 from being provided to each control device 102.

  Further, for example, since it is not necessary to set new information for each control device 102, an information distribution system 201 with a simple configuration and processing can be realized.

  Further, in the management server 151 in the modification of the information distribution system 201 according to the sixth exemplary embodiment of the present invention, when the providing unit 34 receives an information request from the control device 102, the correspondence stored in the storage unit 31. By referring to the relationship, that is, the correspondence between the instance and the IP address and device type information of the control device 102, the control device that is the transmission source of the information request based on the IP address and the device type information included in the information request The instance corresponding to 102 is specified, and the specified instance is provided to the control apparatus 102.

  With such a configuration, even when the control device 102 makes an information request to the management server 151 after the control device 102 specifies information included in the instance to the management server 151, the control The instance specified by the device 102 can be accurately identified and provided.

  The above embodiment should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
