  The home system 2 monitors and / or controls one or a plurality of devices 12, grasps the behavior of a user who uses the home system 2, and supplies power to the devices 12 according to the operation state of the devices 12. The local area network is configured to include a router device 13, an intelligent distribution board 11, and one or more devices 12. In the example illustrated in FIG. 1, the home system 2 is illustrated as being installed in a detached dwelling unit H, and includes a plurality of devices 12-a, 12-b, 12-c,. Although this embodiment demonstrates the case where the home system 2 is installed in the detached dwelling unit H, it is not limited to this, According to the kind of the apparatus 12, and the operation purpose of the home system 2, It is applicable to buildings such as each dwelling unit, government building, hall, commercial building, office building, and factory. Details of the home system 2 will be described later.

  The terminal device 15 receives and displays the operation information regarding the operation state of the device 12 issued from the intelligent distribution board 11 of the home system 2 and displays a monitoring request for requesting monitoring information regarding the operation state of the device 12. Monitoring and / or controlling the device 12 via the intelligent distribution board 11 by transmitting a control request for requesting control of the operating state of the device 12 to the intelligent distribution board 11, and the monitoring result and It is a communicable device that receives and displays control results from the intelligent distribution board 11 as monitoring information. The operation state of the device 12 is the operation state of the device 12 including the usage mode, and the operation information of the device 12 is monitoring information including information regarding the usage mode. The usage mode is how the device 12 is used, and includes the use time and use time of the device 12, the state of the user of the device 12, the user of the device 12, and the use contents of the device 12. The terminal device 15 includes, for example, a mobile communication terminal (for example, a mobile phone), a PDA (Personal Digital Assistants), a PDA (Personal Digital Assistants), and the like provided by software such as a mailer and a web browser, and hardware such as a microprocessor and a communication interface. Portable personal computers and desktop computers.

  The network 14 is, for example, a telephone network, a digital communication network, a wireless communication network, and the like, and data is transmitted using a predetermined communication protocol. The network 14 constitutes the Internet using, for example, a so-called Internet protocol group such as HTTP (Hyper Text Transfer Protocol), FTP (File Transfer Protocol), and TCP / IP (Transmission Control Protocol / Internet Protocol) as a communication protocol.

  Next, the home system 2 including the router device 13, the intelligent distribution board 11, and the device 12 will be described in detail.

  The router device 13 is a device that is arranged at the boundary between the home system 2 and the external network 14 and transmits and receives communication signals between the home system 2 and the network 14, and routes the communication signals according to a routing table (route selection). I do.

  The intelligent distribution board 11 is a device that operates the device 12 safely and also monitors and / or controls the device 12, and is connected to the router device 13 so as to be communicable.

  In this specification, the term “safety” refers to shutting off the power supply of the device 12 when the operation state of the device 12 is placed in a state (non-safe state) set in advance that the user of the home system 2 is not safe. This is to avoid the device 12 from the unsafe state. For example, the user sets a non-safe state in advance according to the operation purpose of the device 12 such as how to operate the device 12. The intelligent distribution board 11 is an evaluation value indicating how safely the device 12 is not operated based on one or more items (safety items) set to operate the device 12 safely. The safety level is calculated, the correspondence (safety action policy) between the safety level and the action to be executed at the safety level is referenced, and the action according to the calculated safety level is performed in order to maintain the safety of the device 12. . As the safety item, for example, an adopted item is selected according to the operation purpose of the device 12 such as how to operate the device 12. For example, what device 12 is (What), who is (Who), when ( When, Where (Where), and How (How). The safety level is safer as the value is smaller, and is not safe as the value is larger. As will be described later, this safety behavior policy is set in advance before the operation of the intelligent distribution board 11 is started.

  For example, as shown in FIG. 2, the intelligent distribution board 11 includes a user authentication unit 21, a monitoring unit 22, and a multi-outlet unit 23. The user authentication unit 21, the monitoring unit 22, and the multi-outlet unit 23 can be configured to be integrated with each other, or can communicate with each other via a communication line so that each unit is configured as an independent unit and can exchange information. It may be connected to. By configuring each unit as an independent unit, when the dwelling unit H is newly constructed, only the multi-outlet unit 23 is first introduced, and then the monitoring unit 22 and the user authentication unit 21 can be retrofitted as necessary. Therefore, the initial introduction cost at the time of new construction can be reduced, and the user incentive (incentive) for the introduction of the home system 2 can be improved.

  The user authentication unit 21 is a device that inputs the behavior of a user who can use the home system 2 (remote monitoring control system 1) to the intelligent distribution board 11 as user behavior information. By providing the user authentication unit 21, a later-described safety level policy can be set according to the user's behavior, and the device 12 can be maintained in a state desired by the user according to the user's behavior. The user behavior information is one of the safety items. In this embodiment, the safety level is, for example, whether the user is in the house (at home) or out of the house (going out), and the user is sleeping. Therefore, the user behavior information is information indicating whether the user is in the house or outside the house, and information indicating whether the user is sleeping. is there.

  In this embodiment, the behavior information of the user indicates whether the user is in the house or outside the house using the ID card that the user has, and whether the user is sleeping. Since input is made to the intelligent distribution board 11, the user authentication unit 21 includes a contact type or non-contact type card reader that reads information of the ID card. In the ID card, a user ID that is an identifier for identifying and specifying the user is recorded as one piece of information of the ID card. The user authentication unit 21 inputs, for example, a reading unit that reads information on an ID card, an output unit that outputs information to the intelligent distribution board 11, a home switch that inputs a home that is home, and an outing that is outside the home A going-out switch, a sleeping switch for inputting sleeping, and a wake-up switch for inputting the wake-up. Then, when the user causes the card reader to read the user ID of the ID card and the user operates either the home switch or the outing switch, the user authentication unit 21 performs the in-home or off-site operation according to the operated switch. The user behavior information is output to the intelligent distribution board 11 together with the user ID. When the user causes the card reader to read the user ID of the ID card and the user operates either the sleep switch or the wake-up switch, the user authentication unit 21 is not sleeping or sleeping according to the operated switch. The action information of the user is output to the intelligent distribution board 11 together with the user ID. The ID card is, for example, a magnetic card or an IC card.

  Here, from the viewpoint of avoiding unauthorized use of an unauthorized user who does not have the authority to use the home system 2 properly, the user authentication unit 21 obtains the user ID of the authorized user who has the authority to use the home system 2 normally. Whether or not the user who is trying to input user behavior information is a regular user is determined based on whether or not the user ID read in advance from the ID card matches the user ID stored in advance. However, if the user is an unauthorized user, the user may be configured to present a warning by sound or light. Further, the user ID may be configured to be encrypted and recorded on the ID card from the viewpoint of improving the security. Encryption methods include public key cryptography and private key cryptography, and a digital signature may be combined with public key cryptography. Then, PKI (Public Key Infrastructure) or GPKI (Government Public Key Infrastructure) may be used for the digital signature.

The monitoring unit 22 includes a central processing unit 31, a storage unit 32, and a communication monitoring unit 33.

  The communication monitoring unit 33 receives the communication signal from the multi-outlet unit 23 and monitors the content of the communication signal so as to collect information corresponding to the safety item. The monitoring content includes, for example, unauthorized access to the home system 2, as well as the IP address of the transmission source, the IP address of the transmission destination, the URL (Uniform Resource Locator) of the access destination, the ID when logging in to a site on the Internet, etc. It is. For example, the correspondence between the ID for logging in to this site and the user name of the ID is stored in the storage unit 32, and the device 12 is actually used by referring to this correspondence based on this ID. The user can be recognized. For example, it is possible to recognize how the device 12 is used by referring to the URL of the access destination. Unauthorized access can be detected, for example, when the communication monitoring unit 33 includes a so-called intrusion detection system (IDS). IDS is a system that detects and detects characteristic patterns and signs of attacks. Network / IDS that detects traffic patterns on the network and hosts / IDS that detect abnormalities on terminals are known. Yes.

(Operation of the embodiment)
First, before starting the operation of the intelligent distribution board 11, the user inputs the safety level policy and the safety behavior policy to the intelligent distribution board 11. When the safety level policy and the safety behavior policy are input, the intelligent distribution board 11 stores the safety level policy and the safety behavior policy in the safety level policy information storage unit 55 and the safety behavior policy information storage unit 56, respectively.

  The safety level policy and the safety behavior policy are input to the intelligent distribution board 11 by displaying information such as an input device for inputting information such as a keyboard and a liquid crystal display (LCD) as shown by a broken line in FIG. It is executed using an input / output unit (setting device) 24 having a display device. For this reason, the monitoring unit 22 is further provided with a connection interface for connecting the input / output unit 24 such as PS / 2 or RGB. Since the safety level policy and the safety behavior policy are not frequently changed information, the monitoring unit 22 is provided with a connection interface so that the input / output unit 24 can be attached to and detached from the monitoring unit 22. The cost of the board 11 can be reduced. Of course, the intelligent distribution board 11 may be configured to always have the input / output unit 24.

  By the user's setting input, for example, the safety level is set and stored as follows. That is, as shown in FIG. 3B, the hourly safety level policy is set to “1” only when the time division is day and night and the user is the user C, and the remainder is all “ 0 "is set. As shown in FIG. 4B, the location-specific safety level policies are “0”, “0”, and “1” when the location classification is in-home and the users are user A, user B, and user C, respectively. Set to When the location classification is outside the home and the users are user A, user B, and user C, the location-specific safety level policies are set to “4”, “3”, and “2”, respectively. As shown in FIG. 6B, when the user in use is the user C and the device name of the device 12 is a game machine, a PC (personal computer), a refrigerator, a microwave oven, and a mobile phone, the device is classified by user. The safety level policy is set to “1”, “2”, “1”, “1”, and “0”, respectively, and the remainder is set to “0”.

  As shown in FIG. 7, when the user in the bedtime event is the user A and the device names of the devices 12 are a game machine, a PC, a refrigerator, a microwave oven, and a mobile phone, the event-specific user safety level policies are “ 1 ”,“ 1 ”,“ 1 ”,“ 1 ”and“ 0 ”, the user in the bedtime event is the user B, and the device name of the device 12 is a game machine, PC, refrigerator, microwave oven and mobile phone , The event-specific safety level policy for each user is set to “0”, “0”, “1”, “1”, and “0”, respectively, and the user in the bedtime event is the user C and the device When the 12 device names are a game machine, a PC, a refrigerator, a microwave oven, and a mobile phone, the event-by-user safety level policy is set to “0”. The event-specific user-specific safety level policies in the unauthorized access event are “1”, “2”, “3”, “4” when the device name of the device 12 is a game machine, a PC, a refrigerator, a microwave oven, and a mobile phone, respectively. "And" 1 ". When the user in the designated site access event is user A and the device name of the device 12 is a game machine, PC, refrigerator, microwave oven, and mobile phone, the event-specific user safety level policies are “NA” and “1”, respectively. ”,“ NA ”,“ NA ”and“ 0 ”, the user in the designated site access event is the user B, and the device name of the device 12 is a game machine, PC, refrigerator, microwave oven and mobile phone The event-specific user-specific safety level policies are set to “NA”, “1”, “NA”, “NA”, and “0”, respectively, and the user in the designated site access event is the user C and the device 12 If the device name is game machine, PC, refrigerator, microwave oven and mobile phone, the safety level policy for each user by event is Each "NA", "3" is set to "NA", "NA" and "3". In addition, when a user accesses the site on the Internet by using a game machine, a refrigerator, and a microwave oven, it is not assumed and “NA” indicating that is set.

  As shown in FIG. 8, when the user is the user C and the device name of the device 12 is a game machine, a PC, a refrigerator, a microwave oven, and a mobile phone, the event-specific device safety level policies are “1”, “2”, “0”, “1” and “0” are set, and the remainder is set to “0”.

  As shown in FIG. 9, the safety action policy is divided into four according to the safety level, and when the safety level is 0 or more and 7 or less, “NOP” indicating that no action is performed is set. When the safety level is greater than 7 and less than or equal to 10, “notification” indicating notification of operation information is set as an action, and when the safety level is greater than 10 and less than or equal to 12, the device 12 is set as an action. Is set to disconnect the link with the currently communicating destination, and if the safety level is greater than 12, the safety information is cut off from the power supply to the device 12 as an action. “Power off” is set. The operation information is, for example, information indicating who is using what device 12 and how. By notifying the operation information in this way, the user's behavior can be monitored. For example, a parent can monitor how a child is using the device 12.

  As described above, when the safety level policy and the safety behavior policy are set in the intelligent distribution board 11 and the operation of the intelligent distribution board 11 is started, the information table processing unit 41 outputs the output of the user authentication unit 21 and the communication monitoring unit. The registration contents of the time information table 111, the location information table 121, the event information table 131, and the device-specific information table 141 are updated according to the output of 33 and the notification time of the clock unit 43.

  That is, for example, when the information table processing unit 41 receives a notification of the current time corresponding to the boundary time of the time segment from the clock unit 43, the information table processing unit 41 sets “ST” to the time segment corresponding to the current time in the time information table 111. While registering, “NS” is registered as another time segment.

  For example, when the information table processing unit 41 receives a notification of the user ID and information indicating that the user is in the house from the user authentication unit 21, the information table processing unit 41 displays “in the user's home field corresponding to the user ID in the location information table 121. "ST" is registered and "NS" is registered in the field outside the house. On the other hand, when the information table processing unit 41 receives a notification from the user authentication unit 21 of the user ID and information indicating that the user is out of the house, the information table processing unit 41 displays “ "ST" is registered, and "NS" is registered in the home section.

  Further, for example, when the information table processing unit 41 receives a notification of the user ID and information indicating that the user is sleeping from the user authentication unit 21, each information table processing unit 41 stores each of the user devices corresponding to the user ID in the event information table 131. Register “ST” in the column. On the other hand, when the information table processing unit 41 receives notification from the user authentication unit 21 of the user ID and information indicating that the user is not sleeping, the information table processing unit 41 displays the information in each column for each user device corresponding to the user ID in the event information table 141. Register “NS”.

  Also, for example, when the information table processing unit 41 receives a notification from the communication monitoring unit 33 that there has been unauthorized access from the external network 14 and the communication port ID of the communication port 82, the information table processing unit 41 performs the processing based on the communication port ID. By referring to the information table 181, the device 12 that has been illegally accessed is specified, and “ST” is registered in each column of the user of the device 12 in the event information table 131. On the other hand, when the information table processing unit 41 receives notification from the communication monitoring unit 33 that there has been no unauthorized access from the external network 14 and the communication port ID of the communication port 82, the information table processing unit 41, based on the communication port ID. By referencing 181, the device 12 that has lost unauthorized access is identified, and “NS” is registered in each column of the user of the device 12 in the event information table 131.

  Further, for example, when the information table processing unit 41 receives a notification from the communication monitoring unit 33 that the specified site has been accessed, a communication port ID of the communication port 82, and an ID for logging in to the specified site, The device 12 that has accessed the designated site is identified by referring to the device information table 181 based on the communication port ID, and “ST” is displayed in the user column corresponding to the ID of the device 12 in the event information table 131. sign up. When the information table processing unit 41 receives a notification from the communication monitoring unit 33 that the user has logged out from the designated site and the communication port ID of the communication port 82, the information table processing unit 41 refers to the device information table 181 based on the communication port ID. The device 12 logged out from the site is specified, and “NS” is registered in each column of each user of the device 12 in the event information table 141.

  Further, for example, when the information table processing unit 41 receives a notification from the communication monitoring unit 33 that the device 12 has been logged in, and the communication port ID of the communication port 82 and the ID for logging in to the device 12, the communication is performed. The logged-in device 12 is identified by referring to the device information table 181 based on the port ID, and “ST” is registered in the user column corresponding to the ID of the device 12 in the device-specific information table 141. When the information table processing unit 41 receives a notification from the communication monitoring unit 33 that the device 12 has logged out and the communication port ID of the communication port 82, the information table processing unit 41 logs out by referring to the device information table 181 based on the communication port ID. The device 12 is identified, and “NS” is registered in each column of each user of the device 12 in the user identification information table 141.

  The information table processing unit 41 activates the evaluation processing unit 42 when any of the registered contents of the time information table 111, the location information table 121, the event information table 131, and the device-specific information table 141 is updated.

  When activated, the evaluation processing unit 42 executes a safety action process. FIG. 11 is a flowchart showing the operation of the safety action process. In FIG. 11, the evaluation processing unit 42 first collects registration contents of the time information table 111, the location information table 121, the event information table 131, and the device-specific information table 141 (S11). For example, the registration contents of the time information table 111, the location information table 121, the event information table 141, and the user identification information table 151 are as shown in FIGS. 3A, 4A, 6 and 7A, respectively. Then, in the evaluation processing unit 42, the time division is night, the user A is out of the house, the user B is out of the house, the user C is in the house, and the users A, B, and C are not sleeping. There is no unauthorized access to each device 12, and the user C accesses the designated site using the device 12 that is a PC, and acquires information that the user C is logged in to the device 12 that is a PC.

  Next, the evaluation processing unit 42 includes safety level policy information, that is, a time-specific safety level policy table 161, a location-specific safety level policy table 162, an event-specific user-specific safety level policy table 163, and an event-specific device-specific safety level policy table. 164 and the user-specific device-specific safety level policy table 165, the time-specific safety level, the location-specific safety level, the event-specific user-specific safety level, the event-specific device-specific safety level, and the user-specific device according to the collected registration contents A different safety level is calculated, and the safety level is calculated by calculating the sum of these (S12). For example, the evaluation processing unit 42 first calculates the hourly safety level by the above-described calculation method. In the above case, since the current time segment is night, the hourly safety level is calculated as 0 + 0 + 1 = 1. Next, the evaluation processing unit 42 calculates the location-specific safety level by the calculation method described above. In the above-described case, since user A is outside the house, user B is outside the house, and user C is inside the house, the location-specific safety level is calculated as 4 + 3 + 1 = 8. Next, the evaluation processing unit 42 calculates the event-specific user-specific safety level by the above-described calculation method. In the above case, since each user A, B, C is not sleeping, the safety level for each event in the sleeping event is 0 and each device 12 has no unauthorized access. The safety level for each user is 0, and the user C accesses the designated site using the device 12 that is a PC. Therefore, the safety level for each user for the event in the designated site access event is 3. The event-specific user safety level is calculated as 0 + 0 + 3 = 3. Next, the evaluation processing unit 42 calculates the event-specific device-specific safety level by the above-described calculation method. In the above case, since the user C accesses the designated site using the device 12 which is a PC, the event-specific device-specific safety level is 2. Next, the evaluation processing unit 42 calculates a safety level for each user identification by the calculation method described above. In the above-described case, since the user C is logged in to the device 12 that is a PC, the safety level for each user identification is 2. Then, the evaluation processing unit 42 sets the safety level by time: 1, safety level by location; 8, safety level by user by event; 3, safety level by device by event; 2 and safety level by user identification. ; Sum of 2; 1 + 8 + 3 + 2 + 2 = 16 is calculated.

  Next, the evaluation processing unit 42 evaluates the calculated safety level. That is, the evaluation processing unit 42 acquires action information corresponding to the calculated safety level using the safety action policy table 171 (S13). For example, in the above-described case, the evaluation processing unit 42 refers to the safety behavior policy table 171 and acquires the power shutdown as behavior information corresponding to the safety level;

  Next, the evaluation processing unit 42 executes an action corresponding to the acquired action information (S14), and ends the safe action process. For example, in the above-described case, the evaluation processing unit 42 outputs a control signal indicating that to the breaker drive control unit 71 in order to shut off the power of the device 12; Upon receiving this control signal, the breaker drive control unit 71 opens the breaker corresponding to the power supply port 73 to which the device 12; PC is connected.

  As described above, the intelligent distribution board 11 according to the present embodiment collects the output of the user authentication unit 21, the output of the communication monitoring unit 33, and the notification time of the clock unit 43, and based on the safety level policy preset by the user. The safety level corresponding to the collection result is calculated, and the action corresponding to the calculated safety level is executed with reference to the safety action policy set in advance by the user. For this reason, the apparatus 12 can be maintained in a state desired by the user. And when it becomes the operation state which should interrupt | block the power supply of the apparatus 12 which the user preset, since the electric power supply of the apparatus 12 is interrupted without waiting for the control from the terminal device 15, the safety | security of the apparatus 12 is maintained. Can do.

  Here, in the case of shutting off the power supply of the device 12 in the processing S14 of the above-described embodiment, the communication that accommodates the information that the power supply is shut down in the device 12 that shuts off the power supply before the power supply is shut off. A signal (blocking notification signal) may be transmitted. Thus, by notifying the device 12 of the interruption of the power supply, the device 12 can execute a procedure to be executed before the power supply is interrupted. For example, when the device 12 is a hard disk device, the magnetic head for storing information on the hard disk is retreated from the hard disk, or when the device 12 is a computer device, the information to be stored is only a volatile storage element. Such as storing information stored in the non-volatile storage element and presenting to the outside that the power supply is interrupted to notify the user.

  Further, from the viewpoint of ensuring that the device 12 performs the action to be performed before cutting off the power supply, after receiving a reply to the cutoff notification signal, the power supply to the device 12 is cut off. You may comprise.

  In the above-described embodiment, the device 12 transmits device information to the intelligent distribution board 11 excluding device-specific information, safety level policy information, safety behavior policy information, and information related to the power port 73 and the communication port 82.
