Embodiment 1 FIG.
As shown in FIG. 1, device management system 100 according to Embodiment 1 of the present invention is a system for reducing energy consumption in residences A and B, and uses data collected and managed for that purpose. And you can watch the safety of those who live in different houses.

  As shown in the figure, a device management system 100 includes a device management device 101a installed in a residence A and used by the resident, a device management device 101b installed in the residence B and used by the resident, and a device management device. A server apparatus 103 that communicates with each of 101a and 101b via the external network 102 is provided. In the present embodiment, the example in which the device management system 100 includes two device management apparatuses 101a and 101b will be described. However, the number of the device management apparatuses 101a and 101b included in the device management system 100 is three or more. May be.

  The external network 102 is a wide-area network constructed outside the dwellings A and B, wired, wireless, or a combination thereof, and is typically the Internet. Through the external network 102, the server apparatus 103 can communicate with the terminal apparatus 104 as shown in FIG.

  The terminal device 104 is a mobile device used by a resident of the residence A, for example, and is, for example, a smartphone or a tablet computer. Accordingly, for example, by executing a software program installed in the terminal device 104, the resident of the residence A transmits information and instructions from the outside to the server device 103 using the terminal device 104, and the server device 103 You can browse the information provided by.

  The terminal device 104 may communicate with, for example, the device management apparatus 101a via the external network 102 and the server apparatus 103 or directly via the external network 102. Thereby, for example, by executing a software program installed in the terminal device 104, the resident of the residence A transmits information and instructions from the outside to the device management device 101a using the terminal device 104, and manages the device. Information provided from the device 101a can be browsed.

  The device management apparatus 101a is an apparatus that monitors the energy consumption in the residence A, and controls the electrical device 105 that is installed in the residence A and used by the resident, as shown in FIG. It communicates with each of the energy measuring device 107 which measures the consumption of energy in the electric equipment 105 and the residence A via the home network 106 constructed by wired, wireless or a combination thereof.

  In the drawing, a television receiver (TV) 105a and an air conditioner (RAC; Room Air Conditioner) 105b are shown as examples of the electric device 105, but the electric device 105 is not limited to these. As another example of the electric device 105, a lighting device, a refrigerator, a microwave oven, an IH (Induction Heating) cooking heater, a hot water washing toilet seat, an electric hot water supply system, an electric vehicle, and bidirectional electric power connected to the electric vehicle for charging and discharging A conversion apparatus, a storage battery, etc. can be mentioned.

  The energy measuring device 107 includes a flow meter 108 that measures the flow rate of gas, tap water, and the like, an ammeter 110 that measures the value of the current flowing through the lamp line 109 for supplying power to the electrical device 105 in the residence A, and the like. Connected. In the present embodiment, the electricity flowing through the lamp line 109 is supplied from the system power supply 111 as shown in the figure. However, when an electric hot water supply system, an electric vehicle, a storage battery, etc. are installed, the electricity is supplied from these. It may be supplied.

  The flow meter 108 is, for example, a pulse type flow meter, and outputs data indicating the measured flow rate to the energy measuring device 107. The ammeter 110 outputs data indicating the measured current value to the energy measuring device 107. The energy measuring device 107 collects data output from the flow meter 108 and the ammeter 110 and outputs the collected data to the electrical equipment management device 101a.

  It is known that harmonics are generated when the electric device 105 operates. This harmonic has a characteristic shape according to the type of the electric device 105. Using this, for example, the energy measuring device 107 outputs operation status data indicating the operating status of the electrical device 105 to the electrical device management apparatus 101a based on the current value indicated by the data output from the ammeter 110. May be.

  Specifically, for example, the energy measuring device 107 stores in advance harmonic feature amounts corresponding to the type of the electric device 105 and extracts a harmonic component from the current value indicated by the data output from the ammeter 110. The extracted harmonic component may be compared with the pre-stored harmonic feature quantity. As a result, the operating electric device 105 can be detected, so that operation status data of the electric device 105 can be generated.

  In addition, in the figure, an example is shown in which one ammeter 110 measures all currents flowing through the lamp line 109. However, the ammeter 110 is connected to each lamp line 109 branched by a distribution board 112, for example. It may be provided. According to this, the ammeter 110 can measure a current for each branched lamp line 109. Furthermore, the energy measuring device 107 may store in advance data indicating the branch destination of the lamp line 109 to which each electric device 105 is connected. According to this, for example, when a plurality of TVs 105a, which are the same type of electric equipment 105, are provided in the residence A and any operation of the TV 105a is detected by the above-described method based on harmonics, the plurality of TVs 105a are turned on. If it is not connected to the same branch destination of the line 109, the energy measuring device 107 can specify which of the plurality of TVs 105a whose operation is detected. Therefore, even if the energy measuring device 107 is a case where a plurality of electric devices 105 of the same type are installed in the residence A, the operation status data of the electric devices 105 in which the individual electric devices 105 are distinguished are measured. Can be generated based on the current value.

  As shown in the figure, the device management apparatus 101a communicates with the terminal apparatus 104 via a wireless network, for example. Accordingly, for example, by executing a software program installed in the terminal device 104, the resident transmits information and instructions to the device management apparatus 101a using the terminal device 104, and is provided from the device management apparatus 101a. Information can be browsed.

  Similarly to the device management apparatus 101a, the device management apparatus 101b is connected to the energy measuring apparatus 107 and the electric apparatus 105 via the home network 106 in the same manner as the device management apparatus 101a. The device management apparatus 101b also monitors the energy consumption in the residence B, and controls the electrical device 105 installed in the residence B and used by the resident as necessary. Of course, the type and number of electrical devices 105 connected to the power line 109, the number of branches of the power line 109, and the like can be appropriately changed in each of the residences A and B.

  In a general device management system 100 installed to reduce energy consumption in the homes A and B, operation status data of devices installed in the homes A and B, such as the electrical device 105, is collected and the operation of the devices is collected. In many cases, operation history data indicating a situation history (operation history) is collected and managed. In the device management system 100 according to the present embodiment, using the operation history data, the safety of the resident of the residence B who is the person to be watched over is monitored as a person who watches the resident of the residence A. The equipment included in the operation status data includes, for example, the electrical equipment 105, equipment management apparatuses 101a and 101b, equipment using gas or tap water, and the like.

  Hereinafter, in order to realize the watching function that is a characteristic function of the device management system 100 according to the present embodiment, the configuration and devices of the device management system 100 (device management apparatuses 101a and 101b and the server apparatus 103) are provided. The processing executed by the management system 100 will be mainly described. In this embodiment, since the resident of the residence A watches the safety of the resident of the residence B (see FIG. 1), the device management device 101a corresponds to the device management device on the side to watch, and the device management device 101b This corresponds to the device management apparatus on the side to be watched over.

  As shown in FIG. 3, the device management apparatus 101a is, for example, a button, a touch panel, or the like, and includes an input unit 113 that receives input by a user (in the case of the device management apparatus 101a, a resident of the residence A), and a liquid crystal display, for example. And a display unit 114 that displays an image for presenting character information, image information, and the like to the user. The display unit 114 corresponds to a first display unit.

  Further, the device management apparatus 101a further physically includes, for example, one or a plurality of processors, a ROM (Read Only Memory), a RAM (Random Access Memory), an SSD (Solid State Drive), an external network 102, and a home network 106. Each has a communication interface corresponding to each, and functionally includes processing / control units 115 to 125 as shown in FIG. These functions are realized, for example, as functions exhibited by the cooperation of a processor that executes a preinstalled software program, a communication interface, an SSD as a storage medium, and the like. The device management apparatus 101a may be a dedicated apparatus or a general-purpose computer.

  In the following, the functions of the processing / control units 115 to 125 will be described using the device management apparatus 101a as an example. However, the device management apparatus 101b may be configured physically and functionally in the same manner as the device management apparatus 101a. .

  The operation status acquisition unit 115 performs processing for causing the server apparatus 103 to collect and manage the operation status data. Specifically, the operation status acquisition unit 115 acquires the operation status data from the electrical device 105 and the energy measurement device 107 via the home network 106, and sends the acquired operation status data to the server device 103 via the external network 102. Send.

  The operation status included in the operation status data includes, for example, the operation content of the device changed according to the user's operation and the date and time when the change occurred.

  For example, the operation status of the TV 105a includes ON (operation) and OFF (stop) switching by the remote controller, and the date and time. Note that the operation status of the TV 105a may include, for example, a change of a viewing channel and the date and time.

  The operation status of the RAC 105b includes, for example, the operation details of the remote controller by the user (switching between ON and OFF, switching of operation modes such as cooling / heating / dehumidification / air blowing, switching of set temperature, etc.) and the date and time of the operation. Including.

  The operation status of the device management apparatus 101a includes, for example, details of operations performed by the user on the device management apparatus 101a (switching between ON and OFF, pressing of various buttons, etc.) and the date and time of the operation.

  The operation status of the device using gas or tap water includes whether or not the device using gas or tap water is used and the date and time when the change occurred. Whether or not a device that uses gas or tap water is used is determined, for example, by the presence or absence of the flow of gas or tap water in the gas pipe or water pipe. In addition, the operation state of the apparatus using gas or water supply may include, for example, a change in flow rate that is equal to or greater than a predetermined threshold and the date and time when the change occurred.

  For example, when the power of the device management apparatus 101a is turned on, the user login data acquisition unit 116 performs processing for the user to log in to the device management apparatus 101a. Specifically, the user login data acquisition unit 116 acquires user login data that is data for a user to log in to the device management apparatus 101a, and transmits the user login data to the server apparatus 103 via the external network 102. .

  In addition, for example, the user login data acquisition unit 116, in response to a user input to the input unit 113, a user login holding flag (for example, 0) indicating whether or not the device management apparatus 101a is logged in (user login state). Or data indicating 1) is read / written. A user login holding flag of “0” indicates, for example, that the user login state is not set. A user login holding flag of “1” indicates, for example, a user login state.

  When the user login retention flag is “1”, the user login data acquisition unit 116 acquires the user login retention flag, and transmits the acquired user login retention flag to the server device 103 as user login data. When the user login holding flag is “0”, the user login data acquisition unit 116 includes a login ID (Identification Data) for identifying the user and a password (login password) corresponding to the login ID. User login data is acquired from the input unit 113 and transmitted to the server device 103.

  The watching application unit 117 is a processing unit for applying to the watching target person for watching. Specifically, the watching application unit 117 generates application data indicating a watching application in response to an input to the input unit 113 by a user who is a watching person (in this embodiment, a resident of the house A). The applied application data is transmitted to the server apparatus 103 via the external network 102.

  The watch approving unit 118 is a processing unit for responding to approval or rejection of an application when the person to be watched receives a watch application. Specifically, when the watch approving unit 118 acquires application data from the server device 103 via the external network 102, the content of the application data is displayed on the display unit 114 via the first display control unit 124. The watch approving unit 118 generates response data in response to an input to the input unit 113 by a user (in this embodiment, a resident of the house B) who has browsed the contents of the application data, and the generated response data is transmitted to the external network. It transmits to the server apparatus 103 via 102. The response data is data indicating approval or rejection of the monitoring application indicated by the application data acquired by the monitoring approval unit 118.

  The watching application by the watching application unit 117 and the watching approval by the watching approving unit 118 are necessary as a premise for the watching person to watch over the safety of the watching target person. In the present embodiment, by approving the watch application, the watcher is allowed to watch the safety of the watch target person based on the safety data indicating whether the watch target person is safe (watch by the safety data). .

  The safety display setting data acquisition unit 119 performs processing for setting the display of the content of the safety data when watching by the safety data is permitted. Specifically, the safety display setting data acquisition unit 119 acquires safety display setting data based on a user input to the input unit 113, and sends the acquired safety display setting data to the server apparatus 103 via the external network 102. Send.

  The safety display setting data is data indicating settings related to the display of the content of the safety data, and includes a safety display device and a safety display timing in the present embodiment.

  The safety display device is a device that displays the contents of the safety data, and is selected from the devices used by the person watching. The safety display timing is a timing at which the content of the safety data is displayed on the safety display device, and is, for example, “when the power is turned off after 21:00” or “when the power is turned on after 21:00”.

  For example, when the safety display device is “TV” and the safety display timing is “when the power is turned off after 21:00”, the content of the safety data is displayed when the watcher stops the TV 105a after 21:00. It is displayed on the screen of the TV 105a for several seconds. For example, when the safety display device is “TV” and the safety display timing is “when the power is turned on after 21:00”, the content of the safety data is displayed when the watcher operates the TV 105a after 21:00. Is displayed on the screen of the TV 105a for a few seconds. That is, it is desirable that the safety display device and the safety display timing are selected so that the person who watches can securely view the contents of the safety data.

  The watch login data acquisition unit 120 performs a login (log-in for watching) process for watching the safety of the watching target person using an index (index for watching) that represents the amount of activity of the watching target person in more detail than the safety data.

  Here, the monitoring index is an index created based on the operation history of the device, and changes according to the amount of activity of the person being watched over in a predetermined time zone. The watch index is created, for example, by performing a predetermined process on the operation history indicated by the operation history data.

  If the person who watches the operation history of the device browses the device as it is, the operation state of the device can be specified individually and specifically, and the detailed life movement of the person to be watched becomes clear to the person watching. Detailed life movements are generally private matters that you do not want others to know. Even if the person to watch over is limited to specific staff at the care center or the family of the target person (for example, children), privacy is disclosed to the person being watched over through the operating status of the device. Some people do not like it.

  If it is an index for watching, the person watching it can estimate the amount of activity of the watching target person in a predetermined time zone by browsing it. On the other hand, since the monitoring index is created by processing the operation history, even if the monitoring index is browsed, the operation status of the device cannot be specified individually and specifically. For this reason, even if the monitoring index is browsed, there is almost no risk that the detailed living behavior of the watching target person will be revealed to the watching person. Therefore, according to the present embodiment, it is possible to watch the safety of the watching target person without losing the comfort of life by protecting the privacy of the watching target person.

  As a detailed example of such an index for watching, a comprehensive value created by performing statistical processing on a plurality of operation histories on the watching target side can be given. For example, in the monitoring index according to the present embodiment, the device is not used in a predetermined time zone such as from a certain time (24 hours) before to the present (for example, when the index is created). It is a value obtained by integrating time.

  Here, “not used” may be that the vehicle is stopped, but in this embodiment, it is assumed that the operation associated with the operation of the watching target person is not performed. For example, the TV 105a and the RAC 105b are both electrical devices 105 that operate in accordance with the operation of the watching target person. On the other hand, for example, since the refrigerator is normally operating, it is not the electric device 105 that operates in accordance with the operation of the person being watched over. Therefore, when creating the watch index according to the present embodiment, the operation history of the TV 105a and the RAC 105b is referred to, but the operation history is not referred to even if the refrigerator is installed in the house A.

  Specifically, the monitoring index according to the present embodiment includes the time when the TV 105a and the RAC 105b are OFF within 24 hours from the present time, and the respective flow rates of the gas and tap water are 0 (or threshold values). It is a value obtained by adding up the time that is smaller and the time that can be regarded as 0). In this case, the safety estimation index is, for example, a maximum of 96 (= 4 × 24 hours). The longer the time during which the TV 105a is operated (turned on), the time during which the RAC 105b is operated, the time during which gas is used, and the time during which tap water is used, the smaller the indicator for watching. . Since the time for operating the TV 105a, the time for operating the RAC 105b, the time for using the gas, and the time for using the tap water are considered to be the time for the person being watched over, It can be said that the monitoring index decreases as the activity of the watching target person increases.

  Note that the watch index may be, for example, a moving average of time intervals of all operations performed on devices managed by the device management apparatus 101b on the watch target side. For example, the monitoring index may be the number of times the device used when creating the monitoring index is used in a predetermined time zone.

  Specifically, the watch login data acquisition unit 120 acquires watch login data for logging in for watching when an instruction to browse the watch index is received in response to a user input to the input unit 113. The watching login data acquisition unit 120 transmits the acquired watching login data to the server device 103 via the external network 102.

  In addition, for example, the watch login data acquisition unit 120, in response to a user input to the input unit 113, a watch login holding flag (for example, 0 or 0) indicating whether or not the watch login is performed (watch login state). 1). A watch login holding flag of “0” indicates, for example, that the watch login state is not set. A watch login holding flag of “1” indicates, for example, a watch login state.

  If the watch login data acquisition unit 120 holds the watch login state, the watch login data acquisition unit 120 further includes a login ID for identifying the watch target person and a password (password for watching) corresponding to the login ID. Retain data.

  When the watch login holding flag is “1”, the watch login data acquisition unit 120 acquires the watch target data, and transmits the watch target data to the server device 103 as the watch data. When the watch login holding flag is “0”, the watch login data acquisition unit 120 acquires the watch login data including the login ID for identifying the watch target person and the watch password from the input unit 113 to obtain the server. To the device 103.

  When the login ID for identifying the person to be watched and the password for watching are correctly input to the device management apparatus 101a on the watching side, or when it is kept in the watching login state, Login is successful. In this embodiment, on the assumption that the watch application has been approved, when the watch login is successful, the watcher watches the safety of the watch target person using the watch index (according to the watch index). Watching) is allowed.

  As the watching password according to the present embodiment, a login password corresponding to the login ID of the watching target person is adopted. Note that the login ID and the password for watching for identifying the watching target person are different from the login ID and the login password for the resident of the residence B who is the watching target to log in to the device management apparatus 101b. It may be set.

  The user schedule acquisition unit 121 performs a process for causing the server device 103 to collect and manage user schedule data indicating a user schedule, that is, a schedule for each date and time. Specifically, the user schedule acquisition unit 121 acquires user schedule data indicating a user schedule, that is, a schedule for each date and time, from the input unit 113. The user schedule acquisition unit 121 transmits the acquired user schedule data to the server apparatus 103 via the external network 102.

  For easy entry and management, the schedule may be entered by selecting a predetermined content from a list for each item such as scheduled content and date / time, and the user uses a software keyboard or the like And may be freely input.

  The watch data acquisition unit 122 acquires watch data for watching the watch target person from the server device 103 via the external network 102. The watch data includes, for example, a watch indicator. The watching data acquisition unit 122 outputs the acquired watching data to the first display control unit 124.

  The safety data acquisition unit 123 acquires safety data from the server device 103 via the external network 102. The safety data acquisition unit 123 outputs the acquired safety data to each of the first display control unit 124 and the second display control unit 125.

  When the first display control unit 124 acquires data, the first display control unit 124 causes the display unit 114 to display the contents of the data.

  When the second display control unit 125 acquires the safety data from the safety data acquisition unit 123, the second display control unit 125 displays the content of the safety data on the device as the second display unit.

  Specifically, when the safety data indicates that it is not safe, the second display control unit 125 immediately causes the TV 105a set as the safety display device to display the safety data. In this case, the 2nd display control part 125 is good to display continuously until predetermined operation is performed on the TV105a from a user. In this case, the second display control unit 125 watches other devices than those set as safety display devices, such as sending an e-mail or the like to the user (watcher) terminal device 104 via the external network 102. It may be displayed on a device used by a person.

  When the safety data indicates that it is safe, the second display control unit 125 causes the TV 105a set as the safety display device to display the contents of the safety data at the safety display timing. In this case, when the safety display timing arrives, the second display control unit 125 instructs the home network 106 to display an instruction to display the content (safeness) of the safety data acquired from the safety data acquisition unit 123 before that. To the TV 105a. Thereby, the TV 105a displays on the screen for several seconds, for example, that the watching target person is safe.

  The server device 103 includes, for example, a keyboard, a mouse, a liquid crystal display, one or more processors, Rom, RAM, HDD (Hard Disc Drive), SSD, a communication interface corresponding to the external network 102, and the like. Typically, the server apparatus 103 is a general-purpose computer, but may be a dedicated apparatus.

  Specifically, the login determination unit 135 determines whether or not the user management data 126 including the same login ID as the login ID included in the acquired user login data is stored in the storage unit 132. When the user management data 126 including the same login ID as the login ID included in the acquired user login data is not stored in the storage unit 132, the login determination unit 135 determines that login is not permitted.

  When the user management data 126 including the same login ID as the login ID included in the acquired user login data is stored in the storage unit 132, the login determination unit 135 extracts the user management data 126. The login determination unit 135 compares login passwords included in the acquired user login data and the extracted user management data 126, respectively. If the login passwords are the same as a result of the comparison, the login determination unit 135 determines that login is permitted. As a result of the comparison, if the login passwords are different, the login determination unit 135 determines that login is not permitted.

  The login determination unit 135 transmits login determination result data indicating the determination result to the device management apparatus 101a that is the transmission source of the user login data (step S105).

  The user login data acquisition unit 116 of the device management apparatus 101a acquires login determination result data via the external network (step S106), and determines whether or not the login determination result data indicates login permission (step S107). . When it is determined that the login permission is not indicated (step S107; No), the user login data acquisition unit 116 executes the login screen display process (step S101) again.

  If it is determined that the login is permitted (step S107; Yes), the user login data acquisition unit 116 determines whether or not the user login data acquired in step S102 includes an instruction for maintaining the login state (step S102). S108).

  When it is determined that an instruction to hold the user login state is included (step S108; Yes), the user login data acquisition unit 116 updates the user login holding flag held by itself to “1”. Accordingly, the user login state is held in the device management apparatus 101a (step S109).

  When it is determined that an instruction to hold the user login state is not included (step S108; No), or after executing step S109, the user login data acquisition unit 116 displays the first login control unit 124 via the first display control unit 124. The main screen is displayed on the unit 114 (step S110).

  An example of the main screen displayed here is shown in FIG. The main screen shown in the figure is an example of a screen displayed on the display unit 114 of the device management apparatus 101a. On this screen, a watch button and setting buttons for making various settings are displayed. “Unapproved” included in the watch button indicates that the watch is not yet approved. In addition, the transition of power consumption for the day is shown below the current date and time. Further, the schedule of the user of the device management apparatus 101a included in the user schedule data 131 is displayed on the calendar.

Refer to FIG. 11 again.
If the result of determination in step S104 is that login is not permitted (step S111; No), the login determination unit 135 of the server device 103 ends the user login process. If the result of determination in step S104 is login permission (step S111; Yes), the login determination unit 135 determines whether or not the user login data acquired in step S104 includes an instruction to maintain the login state. Is determined (step S112).

  If it is determined that the instruction to hold the user login state is not included (step S112; No), the login determination unit 135 ends the user login process.

  When it is determined that an instruction to hold the user login state is included (step S112; Yes), the login determination unit 135 updates the user management data 126 via the storage control unit 133, thereby changing the user login state. (Step S113) and the user login process is terminated.

  Specifically, the login determination unit 135 updates the user login holding flag of the user management data 126 including the same login ID as the login ID included in the user login data acquired in step S104 to “1”. Thereby, the user login state of the device management apparatus 101a is held in the server apparatus 103 (step S113).

  Thereby, the user login process when the user login state is not held is terminated.

  When the power of the device management apparatus 101a is turned on while the user login state is held by the device management apparatus 101a, the user login data acquisition unit 116 does not execute step S101. Then, the user login data acquisition unit 116 acquires the user login holding flag held by itself as user login data (step S102), and transmits the user login data to the server apparatus 103 via the external network 102 (step S102). S103). The login determination unit 135 that has acquired the user login data determines whether or not to allow the user to log in to the device management apparatus 101a (step S104).

  In the login determination process (step S104) in this case, the login determination unit 135 stores user management data 126 including the same device management apparatus ID as the device management apparatus ID of the apparatus management apparatus 101a that is the transmission source of the acquired user login data. Extract. The login determination unit 135 determines whether or not to permit login based on the user login retention flag included in the extracted user management data 126.

  Specifically, when the user login holding flag is “1”, the login determination unit 135 determines that login is permitted. If the user login retention flag is “0”, the login determination unit 135 determines that login is not permitted. Thereafter, the device management apparatus 101a and the server apparatus 103 execute Steps S105 to S113 as described above.

  Thus, by maintaining the login state, it is possible to save the user from logging in to the device management apparatus 101a.

  Next, the watching application / approval process will be described with reference to FIG. The figure shows an example in which an application for watching is applied from the device management apparatus 101a on the monitoring side to the device management apparatus 101b on the monitoring target side. For example, when an unapproved watching button shown in FIG. 13 is pressed, the device management apparatus 101a starts watching application processing. Then, the first display control unit 124 of the device management apparatus 101a causes the display unit 114 to display a monitoring application screen illustrated in FIG. The user can input the login ID of the watching target person using the software keyboard provided by the input unit 113 on the watching application screen shown in FIG.

  As shown in FIG. 14, the watching application unit 117 of the device management apparatus 101a determines whether to apply for watching based on an input to the input unit 113 by the user (step S121).

  For example, when the user presses the cancel button on the watching application screen shown in FIG. 15, the watching application unit 117 determines not to apply for watching (Step S <b> 121; No). In this case, the watching application unit 117 displays the main screen including the watching button in the unapproved state shown in FIG. 13 on the display unit 114 again via the first display control unit 124 (step S138). Finish the application process.

  Further, for example, when the user presses the application button, the watching application unit 117 determines to apply for watching (Step S121; Yes). In this case, the watching application unit 117 acquires application data including the login ID input on the watching application screen (step S122), and transmits the application data to the server apparatus 103 via the external network 102 (step S123). ). The application data further includes a device management apparatus ID of the device management apparatus 101a that is the transmission source.

  Upon obtaining the application data via the external network 102, the approval determination unit 136 of the server device 103 starts a monitoring application approval process and determines the transfer destination of the application data by referring to the user management data 126 ( Step S124). Specifically, the approval determination unit 136 extracts user management data 126 including the same login ID as the login ID included in the application data. The approval determination unit 136 determines a device management apparatus ID included in the extracted user management data 126 as a transfer destination.

  The approval determination unit 136 transfers the application data to the determined transfer destination (step S125). In the present embodiment, the application data is transferred to the device management apparatus 101b.

  The monitoring approval unit 118 of the device management apparatus 101b, when acquiring the application data via the external network 102, starts the monitoring approval process when the user login is permitted by the above-described user login process, and the first display An approval confirmation screen is displayed on the display unit 114 via the control unit 124. FIG. 16 shows an example of an approval confirmation screen. As shown in FIG. 14, the watch-over approval unit 118 acquires response data according to the content input on the approval confirmation screen (step S126).

  For example, when the “Yes” button is pressed on the approval confirmation screen shown in FIG. 16, the watching approval unit 118 acquires response data indicating approval in response. When the “No” button is pressed on the approval confirmation screen shown in FIG. 11, the watching approval unit 118 accordingly acquires response data indicating rejection.

  The watch approval unit 118 transmits the acquired response data to the server device 103 via the external network 102 (step S127), and ends the watch approval process. The response data includes the device management device ID of the device management device 101a included in the application data and the device management device ID of the device management device 101b that is the transmission source of the response data.

  Upon obtaining the response data via the external network, the approval determination unit 136 of the server device 103 refers to the response data to determine whether or not the watch application has been approved (step S128). Specifically, when the response data indicates approval, the approval determination unit 136 determines that the watching application has been approved (step S128; Yes). When the response data indicates rejection, the approval determination unit 136 determines that the watch application has not been approved (step S128; No).

  If it is determined that the watch application has been approved (step S128; Yes), the approval determination unit 136 updates the approval data 128 via the storage control unit 133 (step S129). The device management device IDs of the watching side and the watching target side included in the approval data 128 updated here are respectively the device management device 101a that is the transmission source of the application data and the device management device 101b that is the transmission source of the response data. The device management device ID.

  When it is determined that the application for watching is not approved (step S128; No), or after executing step S129, the approval determination unit 136 transmits the application data included in the response data acquired in step S128 ( The device management apparatus 101a) is determined as the transfer destination (step S130).

  The approval determination unit 136 transfers the response data acquired in step S128 to the determined transfer destination (step S131).

  When the monitoring application unit 117 of the device management apparatus 101a acquires the response data via the external network 102, the monitoring application unit 117 determines whether or not the monitoring application is approved by referring to the response data (step S132). Specifically, when the response data indicates approval, the watching application unit 117 determines that the watching application has been approved (step S132; Yes). When the response data indicates rejection, the watching application unit 117 determines that the watching application has not been approved (step S132; No).

  When it is determined that the watch application has not been approved (step S132; No), the watch application unit 117 displays a response confirmation screen indicating that the watch application has been rejected via the first display control unit 124. It is displayed on the display unit 114 (step S133).

  An example of a response confirmation screen when the application for watching is rejected is shown in FIG. For example, when the OK button shown in the figure is pressed, the watch application unit 117 displays the main screen including the watch button in the unapproved state shown in FIG. 13 on the display unit 114 via the first display control unit 124, for example. It is displayed again (step S138), and the watching application process is terminated.

  If it is determined that the watch application has been approved (step S132; Yes), the watch application unit 117 displays a response confirmation screen indicating that the watch application has been approved via the first display control unit 124. 114 is displayed (step S134).

  FIG. 18 shows an example of a response confirmation screen when the watch application is approved. As shown in the figure, in the response confirmation screen when the watch application is approved, in addition to the approval of the watch application, the input field for the safety display device and the input field for the safety display timing are displayed. Is done.

  The safety display device may be input, for example, by selecting from a list of devices having a display function among the electric devices 105 managed by the device management apparatus 101a. This list may be set in advance. The figure shows an example in which “TV” is selected.

  Similarly, the safety display timing may be input by selecting from a predetermined list. In the example shown in the figure, time and operation can be selected for the safety display timing. The time may be selected from, for example, times arranged in a predetermined time interval (for example, every 10 minutes). The operation may be selected from a list indicating predetermined operations such as “when OFF” and “when ON”.

  For example, when the OK button is pressed on the response confirmation screen shown in FIG. 18, the safety display setting data acquisition unit 119 acquires the safety display setting data according to the content input on the response confirmation screen (step S135). ). When the content shown in FIG. 18 is input to the response confirmation screen, the safety display setting data includes “TV” as the safety display device and includes “when the power is turned off after 21:00” as the safety display timing.

  The safety display setting data acquisition unit 119 transmits the acquired safety display setting data to the server apparatus 103 via the external network 102 (step S136).

  When the safety display setting data receiving unit 137 of the server device 103 acquires the safety display setting data via the external network 102, the safety display setting data is associated with the content of the safety display setting data and updates the approval data 128 updated in step S129 (step S129). S137). Thereby, the safety display setting data receiving unit 137 ends the monitoring application approval process.

  The monitoring application unit 117 of the device management apparatus 101a causes the display unit 114 to display a main screen including an approved monitoring button illustrated in FIG. 19 on the display unit 114 (step S138), for example. End the application process.

  If the application for watching is approved by such processing, the user of the device management apparatus 101a who is the watcher is allowed to watch the user of the device management apparatus 101b which is the watchee person based on the safety data. FIG. 20 shows a flow of the watching process using the safety data in this case.

  As shown in the figure, the safety estimation index creating unit 138 of the server device 103 determines whether or not a time (a safety estimation timing), for example, a time included in the safety confirmation display timing of the approval data 128 has arrived. The determination is made continuously (for example, at regular time intervals) (step S141). For example, in the case of the approval data 128 illustrated in FIG. 7, the safety estimation index creating unit 138 continuously determines whether or not 21:00 has been reached.

  If the current time is not the safety confirmation time, the safety estimation index creation unit 138 determines that the safety confirmation time has not arrived (step S141; No), and ends the watching process using the safety data.

  When the current time is the safety confirmation time, the safety estimation index creating unit 138 determines that the safety confirmation time has arrived (step S141; Yes). In this case, the safety estimation index creating unit 138 extracts the device management apparatus ID on the monitoring target side of the approval data 128 that has reached the safety confirmation time. The safety estimation index creating unit 138 extracts the operation history data 127 having the same device management device ID as the extracted device management device ID and in a predetermined time zone (for example, within 24 hours from the current time). The safety estimation index creating unit 138 creates a safety estimation index based on the extracted operation history data 127 (step S142).

  The comparison unit 139 compares the safety estimation index created by the safety estimation index creation unit 138 with the threshold indicated by the safety threshold data 130 (step S143). The safety data creation unit 140 creates safety data based on the result of the comparison by the comparison unit 139 (step S144). The safety data includes the safety display timing and the safety display device of the approval data 128 determined to have reached the safety confirmation time in step S141, in addition to the safety of the person being watched over.

  The safety data creation unit 140 determines, as a transmission destination of the created safety data, the device management apparatus 101a indicated by the device management apparatus ID on the side of the approval data 128 that has been determined that the safety confirmation time has arrived in step S141. . The safety data creation unit 140 transmits safety data via the external network to the device management apparatus 101a that is the determined transmission destination (step S145), and ends the watching process using the safety data.

  The safety data acquisition unit 123 of the device management apparatus 101a acquires safety data via the external network (step S146). The safety data acquisition unit 123 outputs the safety data to the second display control unit 125.

  The second display control unit 125 displays the safety of the person being watched over on the TV 105a, which is a safety display device, according to the content of the safety data output from the safety data acquisition unit 123 (step S147). Specifically, if the safety data indicates that the safety data is not safe, the second display control unit 125 immediately displays it on the TV 105a. As a result, immediately after the safety data is created by the safety data creation unit 140, it can be displayed on the TV 105a that the person being watched over is not safe. By watching the display on the TV 105a, the watcher can quickly know that the watchee is not safe and can take appropriate measures.

  When the safety data indicates that the safety data is safe, the second display control unit 125 displays it on the TV 105a at the safety display timing. When the display device and the safety display timing are the contents included in the approval data 128 shown in FIG. 7 and the safety data indicates that it is safe, the second display control unit 125 stops the TV 105a after 21:00. When the operation to be performed is received, the fact that the person being watched over is safe is displayed on the screen of the TV 105a for several seconds.

  In the watching process using the safety data, it is displayed whether or not the person being watched is safe, so that the person watching can easily know the safety of the person being watched over.

  The display device and the safety display timing are designated by the person watching as described above. Therefore, since it is possible to set the display device and the safety display timing that the watcher will surely see, it is possible to reliably check the safety of the watchee.

  If the application for watching is approved, the person to watch can be watched by the safety data. Since the watching target person can be watched by a relatively simple process, it is possible to easily know the safety of the watching target person. If it is the content of safety data, there is a very low possibility that the life movement of the person being watched over will be grasped. Therefore, even if the monitoring by the safety data is allowed by a relatively simple process of applying and approving watching, the risk of threatening the safety of the watching target person is low.

  Note that the safety estimation timing may be set, for example, at one hour intervals. An index for safety estimation is created every hour, and the comparison unit 139 compares them. As a result, if the person being watched over is not safe, the safety data creation unit 140 may create safety data to be immediately displayed on the safety display device and transmit it to the device management apparatus 101a on the watching side. Accordingly, the second display control unit 125 may immediately display on the TV 105a that the person being watched over is not safe. As a result, immediately after the safety data is created by the safety data creation unit 140, it can be displayed on the TV 105a that the person being watched over is not safe. It becomes possible for the watcher to know at an early stage that the watched person is not safe and to take appropriate measures. Moreover, the safety data creation unit 140 may transmit, as safety data, an e-mail or the like indicating that the person being watched over is not safe to the terminal device 104 of the watcher. Thereby, it becomes possible for the watcher to know early that the person being watched over is not safe and to take appropriate measures.

  For example, when it is found from the safety data that the person being watched is not safe, the watcher wants to know the activities of the person being watched in more detail. Then, press the watch button.

  As a result, the device management apparatus 101a starts a watching process using the watching index shown in FIG. The flow of the watching process by the watching index shown in the figure is when the watching login state is not held, that is, when the watching login holding flag of the data held by the watching login data acquisition unit 120 is “0” It is an example.

  The watch login data acquisition unit 120 displays a watch login screen on the display unit 114 via the first display control unit 124 in order to acquire the watch login data (step S151).

  An example of a watch login screen is shown in FIG. As shown in the figure, the watch login screen is configured to include an input field and buttons similar to the login screen (see FIG. 12). The user of the device management apparatus 101a who is a watcher inputs a log-in ID and a watch password for the watch target person to log into the device management apparatus 101b on the watch target side to the watch side device management apparatus 101a.

  Specifically, a login ID for logging in to the device management apparatus 101b by the user of the device management apparatus 101b who is the person to be watched is input in the input field associated with “the login ID of the monitoring target person”. In the input field associated with “the password of the watching target person”, a password for logging in to the device management apparatus 101 b by the user of the device management apparatus 101 b that is the watching target person is input as the watching password. The check box associated with “keep me logged in” is checked when the watch login state is maintained.

  As shown in FIG. 21, the watch login data acquisition unit 120 determines whether or not a watch index browsing instruction has been received (step S152). The monitoring index browsing instruction is an instruction that the watcher browses the monitoring index. Whether or not an instruction for viewing the watch index has been accepted is determined based on, for example, whether or not the login button on the watch login screen shown in FIG. 22 has been pressed.

  If the login button has not been pressed, the watch login data acquisition unit 120 determines that a watch index browsing instruction has not been received (step S152; No), and determines whether or not the watch login has been canceled. (Step S153). Specifically, whether or not the watching login is canceled is determined based on whether or not a cancel button on the watching login screen shown in FIG. 22 is pressed.

  When the cancel button is pressed, the watch login data acquisition unit 120 determines that the watch login has been canceled (step S153; Yes). In this case, the watch login data acquisition unit 120 displays, for example, the main screen shown in FIG. 19 on the display unit 114 via the first display control unit 124 (step S154), and finishes the watch process using the watch index. To do.

  When the cancel button is not pressed, the watch login data acquisition unit 120 determines that the watch login has not been canceled (step S153; No). In this case, the watch login data acquisition unit 120 displays, for example, the watch login screen illustrated in FIG. 22 on the display unit 114 via the first display control unit 124 (step S151).

  When the login button is pressed, the watch login data acquisition unit 120 determines that a watch index browsing instruction has been received as shown in FIG. 21 (step S152; No). In this case, the watch login data acquisition unit 120 acquires watch login data including a login ID and a watch password in accordance with the content input on the watch login screen (step S155).

  At this time, if the check box on the watch login screen is checked, the watch login data acquisition unit 120 acquires watch login data further including an instruction to keep the watch login state. The watch login data acquisition unit 120 updates the watch login hold flag held by itself to “1”, and holds watch target data including the acquired login ID and watch password.

  The watch login data acquisition unit 120 transmits the watch login data acquired to the server device 103 via the external network 102 (step S156).

  When the watch determination unit 141 of the server device 103 acquires watch login data via the external network 102, the watch determination unit 141 starts a watch process using a watch index. The watching determination unit 141 determines whether or not to permit watching monitoring based on the acquired watching login data and the user management data 126 of the storage unit 132 (step S157).

  Specifically, the watching determination unit 141 determines whether or not the user management data 126 including the same login ID as the login ID included in the acquired watching login data is stored in the storage unit 132. When the user management data 126 including the same login ID as the login ID included in the obtained watching login data is not stored in the storage unit 132, the watching determining unit 141 determines that the watching login is not permitted (step S157). No).

  When the user management data 126 including the same login ID as the login ID included in the obtained watching login data is stored in the storage unit 132, the watching determining unit 141 extracts the user management data 126. The watching determination unit 141 compares the watching password included in each of the acquired watching login data and the extracted user management data 126. As a result of the comparison, if the watching password is the same, the login determination unit 135 determines that the watching login is permitted (step S157; Yes). As a result of the comparison, if the watching passwords are different, the login determination unit 135 determines that the watching login is not permitted (step S157; No).

  When it is determined that the log-in for watching is not permitted (step S157; No), the watching determination unit 141 displays the login determination result data for watching indicating that it is determined not to be permitted via the external network. 101a is transmitted (step S158).

  When the monitoring login data acquisition unit 120 of the device management apparatus 101a acquires the monitoring login determination result data via the external network 102, the monitoring login data acquisition unit 120 displays the monitoring login failure screen via the first display control unit 124 (step S159). ). FIG. 23 shows an example of a watch login failure screen.

  As shown in FIG. 21, the watch login data acquisition unit 120 determines whether or not it is determined by the user that it has been determined that the watch login is not permitted, based on the input to the input unit 113 by the user. (Step S160). Specifically, if the OK button on the login failure screen illustrated in FIG. 23 is not pressed, the watching login data acquisition unit 120 determines that the confirmation has not been performed (step S160; No). When the OK button on the login failure screen shown in FIG. 23 is pressed, the watch login data acquisition unit 120 determines that the login has been confirmed (step S160; Yes).

  As illustrated in FIG. 21, when it is determined that it has not been confirmed (step S160; No), the watch login data acquisition unit 120 continues to display the login failure screen (step S159). When it determines with having been confirmed (step S160; Yes), the watch login data acquisition part 120 displays a watch login screen on the display part 114 via the 1st display control part 124 (step S151).

  When it is determined that the watch login is permitted (step S157; Yes), the watch data creation unit 142 of the server device 103 creates a watch index based on the operation history data 127, and the watch index. Is created (step S161). The watch data creation unit 142 transmits the watch data to the device management apparatus 101a via the external network 102 (step S162).

  The watch determination unit 141 determines whether or not the watch login data acquired in step S157 includes an instruction to maintain the watch login state (step S163). When it determines with the instruction | indication which maintains a watch login state not being included (step S163; No), the watch determination part 141 complete | finishes the watch process by the parameter | index for watching.

  When it is determined that an instruction to maintain the watch login state is included (step S163; Yes), the watch determination unit 141 updates the watch permission data 129 via the storage control unit 133, thereby changing the watch login state. (Step S164), and the user login process is terminated.

  Specifically, the watching determination unit 141 acquires, via the storage control unit 133, the device management apparatus ID of the user management data 126 including the same login ID as the login ID included in the watching login data acquired in step S157. . The watching determination unit 141 monitors each of the device management apparatus ID of the device management apparatus 101a that is the transmission source of the acquired watching login data and the device management apparatus ID acquired through the storage control unit 133 and the monitoring target. The monitoring permission data 129 is created as the device management apparatus ID with the side. The watching determination unit 141 stores the created watching permission data 129 in the storage unit 132 via the storage control unit 133. Thereby, the server device 103 holds the watching login state of the device management apparatus 101a as the watching side and the device management apparatus 101b as the monitoring target side (step S164).

  When the monitoring data acquisition unit 122 of the device management apparatus 101a acquires the monitoring data via the external network 102, the monitoring data acquisition unit 122 displays the monitoring screen on the display unit 114 via the first display control unit 124 (step S165).

  FIG. 24 shows an example of the watching screen. This figure shows an example in which the transition of the monitoring index is displayed when the value obtained by integrating the time when the device is not used from 24 hours ago to the present is adopted as the monitoring index. As described above, it can be estimated that the greater the value obtained by integrating the time when the device is not used from 24 hours ago to the present, the smaller the amount of activity of the person being watched over. Therefore, by setting the value that is likely to be unsafe for the person being watched as the danger level, the person watching can intuitively grasp how unsafe the person being watched is visually.

  In the example in the figure, since the monitoring index monotonously increases, it is estimated that the person being watched over is not active for almost a day. Thus, the person watching can take appropriate measures such as calling the person being watched over.

  As shown in FIG. 21, the watch data acquisition unit 122 determines whether or not the watch index is confirmed by the user based on the input to the input unit 113 by the user (step S166).

  Specifically, if the OK button on the watching screen shown in FIG. 24 is not pressed, the watching data acquisition unit 122 determines that the confirmation is not confirmed (step S166; No). When the OK button on the watching screen shown in the figure is pressed, the watching data acquisition unit 122 determines that the watch data has been confirmed (step S166; Yes).

  As shown in FIG. 21, when it determines with not being confirmed (step S166; No), the watching data acquisition part 122 continues the display of a watching screen (step S165). When it determines with having confirmed (step S166; Yes), the watching data acquisition part 122 displays the main screen shown, for example in FIG. 19 on the display part 114 via the 1st display control part 124 (step S167), The watching process using the watching index is terminated.

  When the watch login state is held by the device management apparatus 101a, for example, when the watch button on the main screen (see FIG. 19) of the watch device management apparatus 101a is pressed, the watch login data of the device management apparatus 101a is acquired. For example, in step S151, the unit 120 displays a watch login screen in which watch target data held by the unit 120 is input in advance. Thereafter, the device management apparatus 101a and the server apparatus 103 execute Steps S152 to S167 as described above. Thus, by keeping the watching login state, it is possible to save the user from having to log in to the device management apparatus 101a for watching.

  By performing the watching process using the watch index in this way, it becomes possible for the person watching the degree of safety of the watching target person to be confirmed while protecting the privacy of the watching target person.

  Even if it is impossible to grasp the detailed life movement of the watching target person from the watching index, the watching index changes according to the amount of activity of the watching target person. For this reason, for example, a tendency of a certain level of life rhythm of the person being watched over, such as often going out at a specific time zone in the daytime, can be understood from the watch index. Disclosure of this to unspecified persons has the danger of threatening the safety of the target person.

  In the present embodiment, in order to watch over the watching target person using the watch index, the watching person needs to input a login ID and a watching password for identifying the watching target person. Thereby, it is possible to observe the safety of the watching target person while ensuring the safety of the watching target person's life.

  In the present embodiment, a login ID for logging in to the device management apparatus 101b and a login ID for logging in to the device management apparatus 101b are further used as a login ID and a password for watching to identify the watching target person. A password is adopted. Thereby, the resident of the residence A who is a watcher logs in to the watch management side device management apparatus 101b from the watch side device management apparatus 101a in a pseudo manner, thereby browsing the watch index and being the watch target person. You can watch the resident of a certain house B. Since it is not necessary to separately set and manage a login ID and a password for monitoring to identify the person to be watched over, it becomes possible to easily introduce a system for watching.

  The first embodiment of the present invention has been described above. According to the present embodiment, the safety of the person being watched over can be monitored using the device management system 100 (server device 103, device management device 101a, 101b). Therefore, since it is possible to watch the safety of the person being watched without introducing an independent watch system, it is possible to reduce the cost of introducing the system for watching.

  The present embodiment is not limited to what has been described so far, and may be modified as follows.

  For example, in this embodiment, the resident of the residence A watches the resident of the residence B. However, the device management apparatus 101a and the device management apparatus 101b have the same functions as described with reference to FIG. Therefore, by using the device management apparatuses 101a and 101b, unlike the example described in the present embodiment, the resident of the residence A and the resident of the residence B watch each other, and the resident of the residence B You can also watch over the residents.

  For example, when the device management apparatus 101a is used only on the watching side, for example, the watching approval unit 118 and the user schedule acquisition unit 121 may not be provided. Further, when the device management apparatus 101b is used only on the watching target side, for example, the watching application unit 117, the watching login data acquisition unit 120, the watching data acquisition unit 122, the safety data acquisition unit 123, and the second display control unit. 125 may not be provided.

  For example, the data 126 to 131 stored in the server apparatus 103 may be stored in storage units (not shown) of the device management apparatuses 101a and 101b on the watching side and the watching target side. The processing / control units 133 to 143 of the server apparatus 103 may be included in the device management apparatuses 101a and 101b on the watching side and the watching target side. According to this, the server device 103 may only transfer data between the device management devices 101a and 101b, or may not be provided in the device management system 100. Therefore, for example, even if a failure occurs in one or both of the server apparatus 103 and the monitoring target apparatus management apparatus 101b due to a disaster or the like, the monitoring apparatus management apparatus 101a generates a disaster. Based on the operation history data 127 up to, for example, an indicator for watching can be created. Therefore, since it is possible to confirm the safety of the person being watched immediately before the failure occurs, it becomes possible to watch the person being watched more reliably.

Embodiment 2. FIG.
In the present embodiment, the device management system detects an accident such as an earthquake, and based on the operation history of the device and the user's schedule, whether or not the person to be watched is in the house when the accident occurs (present / absent) ). Then, the device management system notifies the device used by the watcher of the estimation result of the presence / absence of the watchee.

  The device management system according to the present embodiment is generally configured similarly to the device management system 100 according to the first embodiment. In the present embodiment, a description will be given focusing on differences from the device management system 100 according to the first embodiment.

  As shown in FIG. 25, the device management apparatus 201a according to the present embodiment includes an accident sensor 244 in addition to the configuration included in the device management apparatus 101a according to the first embodiment.

  The accident sensor 244 is, for example, a seismic sensor, and is a sensor that measures the shaking of the residence A and transmits measurement data indicating the measurement result to the server device 203 via the external network 102.

  The accident sensor 244 is not limited to a seismic sensor, and may be, for example, a sensor that detects inundation, a sensor that detects gas leakage, a sensor that detects smoke, or the like.

  The device management apparatus 201b may be configured similarly to the device management apparatus 201a.

  As shown in FIG. 26, the server apparatus 203 according to the present embodiment includes an accident detection unit that detects an earthquake as an accident in the residence B where the person to be watched (in this embodiment, the user of the device management apparatus 201b) lives. 245 and a presence / absence estimation unit 246 that estimates whether or not the person to be watched is in the house B when an earthquake is detected by the accident detection unit 245, and a person who watches (in this embodiment, a user of the device management apparatus 201a) ) And a notification unit 247 for notifying the estimation result by the presence / absence estimation unit 246.

  The accident detection unit 245 acquires measurement data from the accident sensor 244 included in the device management apparatus 201b on the monitoring target side via the external network 102. The accident detection unit 245 detects the occurrence of an earthquake based on whether or not the magnitude of shaking indicated by the acquired measurement data is equal to or greater than a threshold value. Specifically, the accident detection unit 245 determines that an earthquake has occurred in the residence B where the device management apparatus 201b that is the transmission source of the measurement data is installed when the magnitude of the shake is equal to or greater than the threshold.

  In addition, when the accident sensor 244 is a sensor that detects flooding, the accident detection unit 245 can detect a flooding accident caused by a typhoon, a tsunami, or the like. When the accident sensor 244 is a sensor that detects a gas leak, the accident detection unit 245 can detect a gas leak accident. When the accident sensor 244 is a sensor that detects smoke, the accident detection unit 245 can detect a fire accident. The accident detection unit 245 may detect an accident based on disaster information provided from a server device (not shown).

  When the accident detection unit 245 detects an earthquake, the presence / absence estimation unit 246 refers to the operation history data 127 and the user schedule data 131 in the storage unit 132 via the storage control unit 133. Here, the operation history data 127 and the user schedule data 131 to be referred to each include the device management device ID of the device management device 201b that is the transmission source of the measurement data in which the earthquake is detected by the accident detection unit 245.

  Based on the operation history data 127 and the user schedule data 131, the presence / absence estimation unit 246 estimates whether there is a watching target person in the house B when an earthquake occurs. Specifically, the presence / absence estimation unit 246 determines whether there is a device such as the electric device 105 used when an earthquake occurs based on the operation history data 127.

  When it is determined that there is a device that is used when the earthquake occurs, the presence / absence estimation unit 246 estimates that the person to be watched is in the house B. If it is determined that there is no device being used when the earthquake occurs, the presence / absence estimation unit 246 determines whether or not there is a plan to go out based on the user schedule data 131.

  When it is determined that there is no plan to go out when the earthquake occurs, the presence / absence estimation unit 246 estimates that the watching target person is in the house B. If it is determined that there is a plan to go out when the earthquake occurs, the presence / absence estimation unit 246 estimates that the person to be watched over is not in the house B.

  The notification unit 247 generates presence / absence estimation data indicating the estimation result by the presence / absence estimation unit 246. The notification unit 247 identifies the device management device ID of the device management device 201b that is the transmission source of the measurement data in which the earthquake is detected by the accident detection unit 245. The notification unit 247 extracts the approval data 128 that includes the same device management device ID as the specified device management device ID as the device management device ID on the monitoring target side.

  The notification unit 247 extracts a device management device ID included in the extracted approval data 128 as a device management device ID on the monitoring side. The notification unit 247 extracts the terminal device address of the user management data 126 including the same device management device ID as the extracted device management device ID. The notification unit 247 transmits the presence / absence estimation data to the terminal device 104 indicated by the extracted terminal device address.

  Note that the notification unit 247 may notify the terminal device 104 by e-mail, for example.

  So far, the configuration of the device management system (device management devices 201a and 201b and the server device 203) according to the present embodiment has been described. From here, operation | movement of the apparatus management system which concerns on this Embodiment is demonstrated.

  The device management system executes presence / absence estimation processing while operating. FIG. 27 is a diagram showing a flow of presence / absence estimation processing according to the present embodiment.

  As shown in the figure, the accident sensor 244 of the device management apparatus 201b measures the shaking in the house B (step S271), and transmits measurement data indicating the measurement result to the server apparatus 103 via the external network 102 ( Step S272).

  When the accident detection unit 245 of the server device 203 acquires from the accident sensor 244 via the external network 102, the accident detection unit 245 determines whether an earthquake has occurred based on the measurement data (step S273). When the magnitude of the shake indicated by the measurement data is smaller than the threshold, the accident detection unit 245 determines that an earthquake has not occurred (step S273; No), and ends the existence estimation process.

  When the magnitude of the shake indicated by the measurement data is greater than or equal to the threshold value, the accident detection unit 245 determines that an earthquake has occurred (step S273; Yes). The presence / absence estimation unit 246 is a house B in which the device management apparatus 201b that is the transmission source of the measurement data acquired in step S272 is installed when an earthquake occurs, that is, when the accident detection unit 245 determines that an earthquake has occurred. It is estimated whether or not there is a person to be watched over (step S274).

  The notification unit 247 acquires the estimation result by the presence / absence estimation unit 246, and transmits presence / absence estimation data including the estimation result to the terminal device 104 via the external network 102 as a device used by the person watching (step S275).

  When the terminal device 104 acquires the presence / absence estimation data via the external network 102, the terminal device 104 displays the estimation result included in the presence / absence estimation data on a display unit included in the terminal device 104 (step S276).

  The terminal device 104 determines whether or not the estimation result displayed in step S276 has been confirmed by a watcher (step S277). For example, when a predetermined button is not pressed, the terminal device 104 determines that it has not been confirmed (step S277; No), and continues displaying the estimation result (step S276).

  For example, when a predetermined button is pressed, the terminal device 104 determines that the terminal device 104 has been confirmed (step S277; Yes), and ends the presence / absence estimation process.

  According to the present embodiment, using the device management system, it is estimated whether or not the person to be watched is in the house when an accident occurs, and the person who watches the estimation result is notified. For example, when it is estimated that the watching target person is in the house when the accident occurs, the watching person can estimate that the watching target person is likely to be unsafe and take appropriate measures. Therefore, since it is possible to watch the safety of the person being watched over when an accident occurs without introducing an independent watch system, it is possible to reduce the cost of introducing the system for watching.
