This will be described in detail later.

  Next, the configuration of the home gateway device 7 will be described.

FIG. 3 is a block diagram for explaining a configuration example of the home gateway device 7 common to the embodiments.

The wired communication unit 25 includes a connection port into which a LAN cable is inserted, a communication circuit, and the like.

  The storage unit 22 stores various information. The storage unit 22 is configured by a storage device such as a semiconductor memory or a hard disk drive, for example.

The control unit 23 includes a processor such as a CPU, a program memory, a working memory, and various interfaces. The control unit 23 implements various processing functions by executing a program stored in the program memory by the processor.
For example, the control unit 23 processes information transmitted to and received from the power measurement device 13 in the distribution board 6, the user terminal 4, and each electrical device 9A. In addition, the control unit 23 processes information transmitted to and received from the server 3.

  The control unit 23 recognizes the device identifier, the operating state, and the accumulated operation time of the electrical device 9A from the device information transmitted from the electrical device 9A. Further, the control unit 23 calculates the power consumption of each electrical device 9A in the home network system 2 based on the measured current waveform transmitted from the power measuring device 13 of the distribution board 6. The control unit 23 generates a device list by associating the device identifier with the operation state, the installation location, the power consumption, and the like, and stores the device list in the storage unit 22. Further, the control unit 23 updates the device list based on the device information and the calculated power consumption.

  The device list includes a device identifier, an operating state, an installation location, and power consumption. The installation location is information that can identify the branch circuit to which the electrical device 9A is connected among the plurality of branch circuits branched by the distribution board 6, for example. In addition, for example, the installation location is information indicating a location where the electrical device 9A such as a living room or an entrance is installed. The control unit 23 acquires information input by the user from the user terminal 4 from the user terminal, and sets an installation location based on the acquired information. The power consumption is the power consumption of the electric device 9A calculated by the control unit 23 as described above.

  The control unit 23 can cause the user terminal 4 to generate a power consumption confirmation screen and a control screen by transmitting the device list to the user terminal 4. Moreover, the control part 23 may be the structure which produces | generates a power consumption confirmation screen and a control screen, and transmits to a user terminal. Furthermore, the control unit 23 may be configured to transmit the device list to the server 3 at a predetermined timing (for example, periodic timing or arbitrary timing).

Next, the configuration of the server will be described.
The server 3 manages various types of information related to the electrical device 9A corresponding to HEMS. For example, when the server 3 receives a control signal from the user terminal 4 via the network 5, the server 3 transmits the received control signal to the home gateway device 7 via the network 5. Thereby, the electric equipment 9A in the home network system 2 can be controlled. Further, the server 3 can acquire a device list from the home gateway device 7 via the network 5 and transmit it to the user terminal 4. Thereby, the server 3 can make the user terminal 4 generate a power consumption confirmation screen and a control screen. The server 3 may be configured to generate a power consumption confirmation screen and a control screen using the device list acquired from the home gateway device 7 and transmit the screen to the user terminal.

FIG. 4 is a block diagram for explaining a configuration example of the server 3 common to the embodiments. In the configuration example illustrated in FIG. 4, the server 3 includes a communication unit 31, a storage unit 32, and a control unit 33.
The communication unit 31 communicates with the home gateway device 7 and the user terminal 4 via the network 5.

  The storage unit 32 stores various information. The storage unit 32 is configured by a storage device such as a semiconductor memory or a hard disk drive, for example. The storage unit 32 stores registration information for each electrical device 9A.

  FIG. 5 is an explanatory diagram illustrating an example of registration information common to the embodiments. The registration information is information in which the device identifier, the operating state of the electrical device 9A, the cumulative operation time zone, and the registered current information (registered current waveform) are associated with each other. The registered current information is measurement information of a current value for each operating state and cumulative operating time period of the electrical device 9A specified by the device identifier, and the measured current value and measuring time for each operating state and cumulative operating time period The relationship is shown. That is, the registered current information is classified and stored for each combination of the device identifier, the operating state, and the cumulative operating time zone of the electrical device 9A. Further, the registered current information may be further classified and stored according to an operating time zone (morning, noon, night, midnight) or the like. Furthermore, information indicating the power consumption may be associated with each operation state of the electrical device 9A. A current waveform can be generated from the relationship between the measurement current value included in the registered current information and the measurement time, and this current waveform is referred to as a registered current waveform. Hereinafter, the registered current waveform may be read as registered current information.

The control unit 33 includes a processor such as a CPU, a program memory, a working memory, and various interfaces. The control unit implements various processing functions by executing a program stored in the program memory by the processor.
For example, the control unit 33 performs processing of information transmitted / received to / from the home gateway device 7 and the user terminal 4. The control unit 33 acquires the device identifier, the operation state, the accumulated operation time, and the measured current waveform of the target circuit from the home gateway device 7. The control unit 33 refers to the registration information stored in the storage unit 32 to acquire a registered current waveform corresponding to the acquired device identifier, operation state, accumulated operation time, and the like.

  Therefore, the control unit 33 is connected to the target circuit acquired from the home gateway device 7 and can measure at least the device identifier of the electrical device 9A and the registered current waveform stored in the storage unit 32. And the registered current waveform can be updated based on the measured current waveform.

  FIG. 6 is a flowchart illustrating an example from measurement current information acquisition to transmission by a power measurement apparatus common to the embodiments. As shown in FIG. 6, the power measuring device 13 measures the current value flowing through the circuit (branch circuit) to be measured in a predetermined period (step S601), and the measured current information indicates the relationship between the measured current value and the measured time. (Information on the current value to be converted according to the passage of time) (step S602). In other words, the power measurement device 13 acquires the measurement current waveform (measurement current waveform that can be generated from the measurement current information) of the target circuit. For example, if the electrical device 9A is connected to the branch circuit, measuring the current value flowing through the branch circuit by the power measuring device 13 corresponds to measuring the current value of the electrical device 9A. In this way, the power measurement device 13 acquires measurement current information from each branch circuit, that is, measurement current information of each electrical device 9A.

  For example, the power measuring device 13 periodically acquires measured current information. Alternatively, the power measuring device 13 acquires measured current information based on an instruction from the home gateway device 7. Alternatively, the power measurement device 13 acquires measurement current information at both of these timings. For example, the home gateway device 7 can acquire information related to the operating state (operating mode) of the electrical device 9A (for example, the device information transmitted from the electrical device 9A includes information related to the operating state). At the timing, it is possible to instruct the power measurement device 13 to acquire measurement current information.

  The power measuring device 13 transmits the acquired measured current information to the home gateway device 7 at a predetermined timing or periodically (step S603). Further, the power measuring device 13 transmits the branch circuit identification information and the measured current information of the branch circuit to the home gateway device 7. That is, the power measuring device 13 transmits the measured current information for each branch circuit to the home gateway device 7.

  FIG. 7 is a flowchart for explaining an example of reception and transmission of various types of information by the home gateway device 7 common to the embodiments. The wireless communication unit 24 of the home gateway device 7 receives (acquires) device information transmitted from the electrical device 9A (step S701). The home gateway device 7 receives (acquires) the measured current information transmitted from the power measuring device 13 (step S701). As described above, since the power measurement device 13 transmits the measurement current information for each branch circuit to the home gateway device 7, the home gateway device 7 can receive the measurement current information for each branch circuit. The control unit 23 recognizes the device identifier of the electric device 9A that transmitted the device information from the acquired device information (step S702). The control unit 23 recognizes the operation state, the accumulated operation time, and the like of the electric device 9A that transmitted the device information from the acquired device information (step S703).

  The control unit 23 updates the operation state, the accumulated operation time, and the like of the electric device 9A that transmitted the device information in the device list based on the recognized operation state, the accumulated operation time, and the like (step S704). For example, the control unit 23 overwrites the operation state and accumulated operation time recognized in step S703 with the operation state and accumulated operation time associated with the device identifier recognized in step S702 of the device list. Thereby, the control part 23 can update the information of an apparatus list sequentially.

  In addition, since the device list includes information (such as branch circuit identification information) that can identify the branch circuit to which the electrical device 9A is connected, the control unit 23 includes the device information included in the device list, the power Measurement current information from the measurement device 13 can be associated. That is, the control unit 23 can associate the measurement current information of each branch circuit with the device information from the electrical device 9A connected to each branch circuit. Note that the user may associate the measurement current information of each branch circuit with the device information from the electrical device 9A connected to each branch circuit via the user terminal 4.

  The wired communication unit 25 of the home gateway device 7 transmits the device information of each electrical device 9A and the measured current information associated with the device information of each electrical device 9A to the server 3 (step S705).

(First embodiment)
FIG. 8 is a diagram for explaining an example of information update processing by the server 3 according to the first embodiment. The communication unit 31 of the server 3 receives the device information from the home gateway device 7 and the measured current information associated with the device information (step S801).

  The control unit 33 of the server 3 classifies the measured current information based on each condition such as a device identifier (model), an operation state (operation mode), and an accumulated operation time included in the device information (step S802), and for each condition. The measured current information is statistically analyzed (step S803), and the registration information for each condition is updated based on the analysis result (step S804). Alternatively, the control unit 33 may sequentially accumulate measurement current information for each condition, which is periodically statistically analyzed, in the storage unit 32.

  For example, the storage unit 32 of the server 3 stores registration information for each condition in advance. The registration information includes a device identifier, an operation state, a cumulative operation time zone, and registration current information. That is, the storage unit 32 stores registration current information for each condition. For example, the registered current information is information obtained from a test operation or calculation of each electric device.

  For example, the power measurement device 13 acquires measurement current information multiple times at different timings. As a result, the communication unit 31 of the server 3 receives the measurement current information for a plurality of times acquired at a plurality of times at different timings via the home gateway device 7, and the control unit 33 receives the measurement for the plurality of times. The measured current information is statistically analyzed, and the current registered current information is updated to the measured current information obtained from the statistical analysis result. For example, the control unit 33 obtains a normal distribution from measurement current information for a plurality of measurements, excludes values that are out of the normal distribution, and updates the registered current information based on the result of calculating the average of the remaining measurement values. To do.

  The initial registered current information is information obtained from, for example, a test operation of each electric device, and may not be suitable for the actual situation. By using the results of long-term and periodic statistical analysis and updating the registered current information, it is possible to obtain registered current information in line with the actual situation. Obtaining registered current information according to the actual situation can lead to accurate calculation of power consumption. That is, it is possible to improve the accuracy of power measurement. Also, by accumulating the results of periodic statistical analysis, it becomes possible to analyze changes in equipment (aging, malfunctions, etc.). As a result, the utility value of the power management system can be increased. In addition, when the registered current information is not prepared in the server 3, it is also possible to register (generate) the registered current information based on information from a device that is actually in operation.

  Moreover, since the control part 33 can receive measurement current information with the operation state from the home gateway apparatus 7, it analyzes statistically the measurement current information for every operation state, and statistically registers the registered current information for every operation state. Update to the measured current information for each operating state obtained from various analysis results. Thereby, the registered current information for each operation state can be updated, and detailed information management and device management become possible. Further, when the registered current information is not prepared for each operation state, detailed current information for each operation state can be obtained by registering the measured current information for each operation state received by the server 3. For example, detailed information management and device management for each operation mode such as cooling (power saving mode), cooling (normal mode), heating, dehumidification, and ventilation can be performed.

  Further, since the control unit 33 can receive the measured current information together with the accumulated operating time from the home gateway device 7, the measured current information is statistically analyzed for each accumulated operating time, and the registered current for each accumulated operating time zone. The information is updated to the measured current information for each cumulative operating time obtained from the statistical analysis results. As a result, the registered current information for each cumulative operating time zone can be updated, and detailed information management and device management are possible. In addition, when the registered current information is not prepared for each cumulative operating time zone, detailed current information for each cumulative operating time zone is obtained by registering the measured current information for each cumulative operating time zone received by the server 3. Can be obtained. For example, if the measured current information has a cumulative operating time of 100 hours, it can be used to update the registered current information in the cumulative operating time period of 0 to 1000 hours. Generally, it is known that the state of an electric device changes according to the accumulated operation time. Therefore, detailed device management can be performed by managing and updating the registered current information for each cumulative operating time zone.

  In addition to the cumulative operation time, the elapsed time from the start of energization of the electric device may be added to the information. That is, the device information may include the elapsed time, and the server 3 may statistically analyze the measured current information for each elapsed time, and update the registered current information for each elapsed time. It is known that the state of an electric device changes depending not only on the cumulative operation time but also on the elapsed time, and more detailed information management and device management can be performed by considering the elapsed time.

(Second Embodiment)

For example, the server 3 is connected to a plurality of home network systems 2 via the network 5. Each home network system 2 is provided in each facility (each household). The communication unit 31 of the server 3 receives the device information from the home gateway device 7 of each facility and the measured current information associated with the device information (step S901).

  The control unit 33 of the server 3 sets each condition (model, various operation modes, and cumulative operation time) such as a device identifier, an operation state, and a cumulative operation time included in the device information from the home gateway device 7 of each facility. Based on the measurement current information (step S902), the measurement current information is statistically analyzed for each condition (step S903), and the registration information for each condition is updated based on the analysis result (step S904).
