The home appliance cooperation unit 214 may acquire device information that is voluntarily transmitted from the electric device 100 after the power is turned on. Alternatively, the household appliance cooperation unit 214 may acquire the device information from the electric device 100 by requesting the electric device 100 to acquire the device information by acquiring the power-on information from the electric device 100. When the communication module 200 and the electric device 100 have common power supply and the communication module 200 is also activated when the electric device 100 is turned on, the device information may be acquired after the activation of the communication module 200 is completed. When acquiring the device information from the electric device 100, the home appliance cooperation unit 214 stores the device information in the module storage unit 213.

When the home appliance cooperation unit 214 receives the log from the electric device 100, the home appliance cooperation unit 214 may store the received log in the module storage unit 213 as a buffer.

When receiving the device registration request from the terminal device 400 via the module communication unit 211, the identification information transmission unit 221 realized by the module control unit 212 as a processing unit reads the device information from the module storage unit 213 and outputs the module communication unit 211. The device information is transmitted to the log acquisition device 300 via the device. When the module control unit 212 receives the registration completion information from the log acquisition apparatus 300, the module control unit 212 stores, in the module storage unit 213, registered information indicating that the device registration process has been completed.

When the communication module 200 is powered on, for example, when the power is switched on with the electric device 100, the identification information transmission unit 221 stores the registered information in the module storage unit 213, the module communication unit 211. Sends a power-on notification to the log acquisition apparatus 300 via The power on notification may include the device information stored in the module storage unit 213.

The notification setting information storage unit 222 realized by the module control unit 212 as a processing unit receives notification setting information when receiving notification setting information including a notification start time and a notification cycle from the log acquisition device 300 via the module communication unit 211. It is stored in the module storage unit 213. A plurality of notification setting information can be registered in the module storage unit 213. In the case of the present embodiment, the notification setting information further includes log specification information for specifying the type of log to be notified. Here, if the notification setting information newly transmitted from the log acquisition apparatus 300 has already been registered in the module storage unit 213, the newly transmitted notification setting information is not saved so that the same notification setting information is not registered in plurality.

The determination as to whether the notification setting information newly transmitted is the same may be determined by any one or a combination of the notification start time, the notification cycle, and the log specification information, or the notification setting information It may be determined by the unique information by adding the unique information indicating the notification setting information. Note that the notification setting information newly transmitted may be overwritten and saved.

The log transmission unit 223 realized by the module control unit 212 as a processing unit reads the notification setting information from the module storage unit 213, and calculates the notification time from the notification start time and the notification cycle. When the notification time is reached, the module control unit 212 creates a log notification request created in advance based on the notification setting information, and transmits it to the home appliance cooperation unit 214. The log notification request includes log specification information which is information indicating the type of log to be notified.

When the home appliance cooperation unit 214 receives the log notification request from the module control unit 212, the module control performs a response indicating whether the log to be transmitted is stored in the module storage unit 213 according to the log specification information included in the log notification request. Send to unit 212. If the log to be transmitted is a log that has already been transmitted from the electric device 100 and buffered in the module storage unit 213, the log transmission unit 223 transmits the log read from the module storage unit 213 to the module communication unit 211. To the log acquisition apparatus 300. When the log to be transmitted is not stored in the module storage unit 213, the log notification request is transmitted to the electric device 100 through the home appliance cooperation unit 214, and the log transmission unit 223 transmits the electric device 100 through the home appliance cooperation unit 214. The log received from the server is sequentially transmitted to the log acquisition apparatus 300 via the module communication unit 211.

When receiving the synchronization signal from the log acquisition device 300, the time management unit 216 performs time calibration to synchronize the time of the communication module 200 with the log acquisition device 300 based on the synchronization signal. Although the timing of performing time calibration is not particularly limited, for example, when the communication module 200 is activated and communication with the log acquisition apparatus 300 is established, the synchronization signal may be acquired to perform time calibration. Also, time calibration may be performed at regular timing. In this case, the module control unit 212 transmits a synchronization signal request to the log acquisition apparatus 300 via the module communication unit 211 at regular timing.

The operation of each functional block in the log acquisition apparatus 300 will be described with reference to FIG.

The log acquisition device 300 holds the product list in the server storage unit 313. The product list is a list of information related to logs to be acquired for each product information, and FIG. 9 is an example thereof. As shown in the figure, in the product list, a notification start time zone and a notification cycle are associated with each piece of log specification information linked to product information. The product list can also be registered from the terminal device 400.

The individual identification information acquisition unit 321 realized by the server control unit 312 as a processing unit receives the device information of the electric device 100 from the communication module 200 during the device registration process via the server communication unit 311 and stores the information in the server storage unit 313. Register device information.

The server control unit 312 performs the subsequent processes with the electric device 100 for which the device registration process has been completed as the target device. The notification cycle determination unit 322 realized by the server control unit 312 as a processing unit reads the product list stored in the server storage unit 313, and notifies the log of the target device based on the product information included in the device information. Determine a certain notification cycle. When the product information included in the device information is an air conditioner, the log information corresponding to the air conditioner may be {00:00 to 00:05, 10-minute cycle, power consumption} and {00:00, as described in the example of FIG. It becomes two things of ~ 00: 04, 5 minute cycle, room temperature / outside temperature. The notification period determination unit 322 determines two different notification periods for the target device based on the read product list. In FIG. 9, 00:10 and 00:05 are determined as notification periods.

When the start time determination unit 323 realized by the server control unit 312 as a processing unit receives the notification period determined by the notification period determination unit 322, the start time determination unit 323 is a table in which notification setting information is associated with each device from the server storage unit 313. A certain notification setting list is read out (see FIG. 11). FIG. 10 is a diagram conceptually showing the distribution of transmission timings of a plurality of electric devices calculated from the notification setting list. The transmission timing is a time calculated based on the notification start time and the notification cycle, and is a timing at which the communication module 200 uploads a log. In the case of determining the start times for the notification cycles 00:10 and 00:05 in the device (air conditioner 4) that newly creates the notification setting, the transmission timing for which diagonal hatching described in the figure is already determined and Then, grid hatching and diagonal grid hatching described in the same drawing indicate transmission timings to be newly determined. The diagonal grid hatching is a transmission timing corresponding to the notification cycle 00:10, and the grid hatching is a transmission timing corresponding to the notification cycle 00:05. The start time determination unit 323 equalizes the distribution of the transmission timing of the log of each electrical device based on the notification period determined by the notification cycle determination unit 322 and the notification start time and notification period of the already determined electrical devices. Thus, the notification start time (circled in FIG. 10) is determined. The start time determination unit 323 creates notification setting information by associating the determined notification start time with the notification cycle corresponding thereto and the device information. The start time determination unit 323 adds the newly created notification setting information to the notification setting list and stores the notification setting information in the server storage unit 313.

The start time determination unit 323 may determine the start time within the range of the notification start time zone linked to the product information.

FIG. 11 shows the registered notification setting list stored in the server storage unit 313, and FIG. 12 shows the notification setting list after new notification setting information is added.

The setting transmission unit 324 realized by the server control unit 312 as a processing unit corresponds to the notification setting information created by the start time determination unit 323 via the server communication unit 311 based on the device information included in the notification setting information. It transmits to the communication module 200 connected to the device 100.

When the notification setting information corresponding to the received device information is already stored, when the device information is received by the power-on notification from the communication module 200, the setting transmitting unit 324 transmits the notification setting information linked to the device information to the server. The notification setting information is read out from the storage unit 313 and transmitted to the communication module 200.

The log acquisition unit 325 realized by the server control unit 312 as a processing unit acquires the notification start time included in the notification setting information and the log transmitted from the communication module 200 according to the notification cycle, and stores the log in the server storage unit 313. . In the case of the present embodiment, the log acquisition unit 325 classifies the log according to the device information included in the log and stores the log in the server storage unit 313. The log may be transmitted to the terminal device 400 via the server communication unit 311.

The synchronization management unit 316 receives a synchronization signal request from the communication module 200 via the server communication unit 311. When receiving the synchronization signal request, the time held by the log acquisition apparatus 300 is transmitted as a synchronization signal to the communication module 200 via the server communication unit 311.

The operation of each functional block in the terminal device 400 will be described with reference to FIG.

When the terminal operation unit 414 detects an operation of device registration by the user, the device registration operation information is transmitted to the terminal control unit 412. When the device registration operation information is input, the terminal control unit 412 transmits a device registration request to the communication module 200 via the terminal communication unit 411.

The terminal control unit 412 can register and add a product list to the log acquisition apparatus 300 via the terminal communication unit 411. Further, when a log is received from the log acquisition apparatus 300 via the terminal communication unit 411, the log is stored in the terminal storage unit 413.

The terminal control unit 412 can analyze the log of the terminal storage unit 413 and display home appliance usage information on the display through the screen output unit 415.

FIG. 14 is a flowchart for explaining a log notification setting flow of the terminal device 400 and the log acquisition system 500 including the electric device 100, the communication module 200, and the log acquisition device 300 according to the embodiment. The operations of the electric device 100, the communication module 200, the log acquisition device 300, and the terminal device 400 will be described with reference to FIG.

When the user performs an operation for turning on the power to the device operation unit 114, the device operating unit 114 detects that the power is turned on, and the electric device 100 is activated. In the present embodiment, since the power supply of the communication module 200 is supplied from the electric device 100, the communication module 200 is also activated here (step S100).

When the electric device 100 and the communication module 200 are activated, the home appliance cooperation unit 214 acquires device information from the electric device 100 and registers the device information in the module storage unit 213 (step S101).

When the communication module 200 is activated and communication with the log acquisition device 300 is established, the time management unit 216 performs time calibration with the synchronization management unit 316 of the log acquisition device 300 (step S102).

Thereby, the time of the log acquisition apparatus 300 and the time of the communication module 200 are synchronized, and the shift of the time which notifies a log to the log acquisition apparatus 300 from the communication module 200 can be prevented. Accordingly, since the time is synchronized with the plurality of communication modules 200 connected to the log acquisition apparatus 300 via the network, the time taken for each communication module 200 to upload the log may be shifted since the time is synchronized. There is no loss of the distributed effect of the timing of notifying the logs. Note that the time calibration may be performed periodically, not only once at the start of the communication module 200. For example, the case of performing once a day on a 24-hour cycle can be mentioned. This is effective for, for example, a refrigerator that has not been turned on for a long time.

After time calibration, the communication module 200 confirms whether or not the electrical device 100 has been registered in the log acquisition device 300 based on the presence or absence of the registered information. If the registered information is held, it is determined that the device is registered, and the device registration processing is not performed (S103: Yes). If there is no registration information, the communication module 200 performs device registration processing (step S103: No).

When the terminal operation unit 414 detects a device registration operation by a user operation, the terminal device 400 transmits a device registration request to the communication module 200. When receiving the device registration request, the communication module 200 performs device registration processing. During the device registration process, the communication module 200 transmits the device information acquired in step 101 to the log acquisition device 300, and the log acquisition device 300 registers the device information transmitted from the communication module 200 in the server storage unit 313 ( Step S104).

When the device registration process is completed, the server control unit 312 starts creation of notification setting information. The server control unit 312 creates notification setting information including a notification start time and a notification cycle based on the product list held in the server storage unit 313 and the acquired device information. At this time, the notification time is determined by the start time determination unit 323 so that the notifications are distributed (step S105).

When the notification setting information is created by the server control unit 312, the notification setting information is registered in the server storage unit 313, and is transmitted to the communication module 200. The notification setting information transmitted to the communication module 200 is registered in the module storage unit 213. At this time, if the notification setting information to be registered is registered, duplicate registration is not performed (step S106).

If the device registration has been completed in step S103, or after completion of the notification setting information registration processing, the communication module 200 transmits a power-on notification notifying that the power is turned on to the log acquisition device 300 (step S107). .

When the log acquisition apparatus 300 receives the power-on notification from the communication module 200, it refers to the device information included in the power-on notification and determines whether notification setting information linked to the device information is registered in the server storage unit 313 or not. Check. If registered, the information is read out and transmitted to the communication module 200. The notification setting information transmitted to the communication module 200 is registered in the module storage unit 213. At this time, if the notification setting information to be registered is registered, duplicate registration is not performed (step S108).

In addition, when it is not registered by step S103, the flow which does not process step S107 and step S108 may be sufficient.

FIG. 15 is a flowchart for explaining the transmission flow of logs of the electric device 100, the communication module 200, the log acquisition device 300, and the terminal device 400 according to the embodiment. The operations of the electric device 100, the communication module 200, the log acquisition device 300, and the terminal device 400 will be described with reference to FIG.

Based on the notification setting information registered in the module storage unit 213, when it is detected that the log transmission unit 223 has reached the transmission timing, the log transmission unit 223 determines whether the log is buffered in the module storage unit 213 or not. It confirms (S201). If the log to be transmitted is buffered by the module storage unit 213 (S201: Yes), the log transmission unit 223 transmits the buffered log (S203). If not buffered (S201: No), the log transmission unit 223 transmits the log acquired from the electric device 100 (S202) via the home appliance cooperation unit 214 (S203).

When the log acquisition device 300 receives the log, the log acquisition device 300 classifies the log according to the product information included in the device information of the transmission source of the log, and registers the log in the server storage unit 313 (S204). The registered log is transmitted to the terminal device 400 for analysis when requested from the terminal device 400. The analysis result of the log is displayed on the display through the screen output unit 415 as home appliance usage information, for example, and provided to the user (step S206).
