<Introduction>
There is a device that has a communication function and uploads and manages measured and collected data to a server on a network. The measured and collected data is not only displayed, but can be stored and further uploaded to a server for operation.

  Hereinafter, as shown in FIG. 1, a power meter 1 will be described as an example of a device according to an embodiment of the present invention. However, the device is not limited to the power meter 1 but may be a thermometer, a hygrometer, an illuminometer, or the like. In this embodiment, a temperature sensor, a humidity sensor, and an illuminance sensor are attached to the power meter 1, and not only power data but also temperature, humidity, and illuminance can be measured.

  The power meter 1 is an example of a simple measuring device that measures power consumption of an electrical product. The power meter 1 is plugged into the outlet 2 and measures and records the power used by the electrical product 3. In FIG. 1, a power meter 1 according to the present embodiment is connected to a television as an example of an electrical product 3 via a power cable 4. The electrical product 3 is an electronic device to be measured and is not limited to a television, but a Blu-ray Disk (trademark) recorder (hereinafter referred to as “BD recorder”), an air washer, a washing machine, a refrigerator, an air conditioner, etc. All electrical products are included.

  The PC 6 is an example of an information processing apparatus that performs processing such as referring to power data measured by the power meter 1 and displaying a transition of power data. Other examples of the information processing apparatus include wearable display devices such as tablet terminals, smartphones, PDAs (Personal Digital Assistants), and HMDs (Head Mount Displays).

[Hardware configuration of power meter]
Next, an example of the hardware configuration of the power meter 1 will be described with reference to FIG. The power meter 1 includes a microcomputer 11, a ROM (Read Only Memory) 12, a power measurement circuit 13, a temperature / humidity / illuminance measurement circuit 14, a wireless circuit 15, a power supply circuit 16, a plug 17, a plug socket 18, and an antenna 19. Have.

  The power meter 1 is equipped with a control microcomputer 11, and the setting file storage location information 31, the power data DB (database) 32, and the temperature / humidity / illuminance data DB 33 are recorded in the ROM 12 inside the microcomputer 11. Is done. The power data measured by the power measuring circuit 13 is temporarily stored in the power data DB 32 built in the microcomputer 11. The temperature data, humidity data, and illuminance data measured by the temperature / humidity / illuminance measurement circuit 14 are temporarily stored in a temperature / humidity / illuminance data DB 33 built in the microcomputer 11.

  The stored power data, temperature data, humidity data, and illuminance data are transmitted to the PC 6 in accordance with an instruction from the PC 6. Therefore, the power meter 1 need not always be connected to the PC 6 to keep transmitting power data. The PC 6 stores a setting file that stores the setting status of the power meter 1. The setting file storage location information 31 is information indicating the storage location of the setting file created on the server at the time of initial setting by the application software 7 installed on the PC 6.

  The wireless circuit 15 is a circuit for wirelessly communicating with other power meters 1 and other devices. The radio circuit 15 performs radio communication with other devices via an antenna 19 for radio communication. When the plug 17 is inserted into an outlet such as a wall, the electrical product 3 is connected to the plug insertion port 18. The power meter 1 is provided with a power measurement circuit 13, a temperature / humidity / illuminance measurement circuit 14, a radio circuit 15, and a power supply circuit 16 that generates power for the microcomputer 11.

[Measurement system]
Next, the measurement system 10 will be described. FIG. 3 shows an example of a measurement system 10 including the power meter 1. The measurement system 10 includes power meters 1a, 1b, 1c, 1d, and PCs 6a, 6b. The power meters 1a, 1b, 1c, and 1d can be connected to each other to form one network group NW. Note that the power meters 1a, 1b,... Are also collectively referred to as a power meter 1. The PCs 6a and 6b are also collectively referred to as PC6.

  The power data measured by the power meters 1a, 1b, 1c, and 1d belonging to the network group NW is referred to by the plurality of PCs 6a and 6b. The power meter 1 and the PC (Personal Computer) 6 and between the power meters 1 are connected by Bluetooth 5 such as Bluetooth (registered trademark, the same shall apply hereinafter).

  In this specification, an example in which Bluetooth is used as a wireless communication method will be described. That is, in the present specification, a Bluetooth wireless communication system is used for communication between the power meters 1 and communication between the PC 6 and the power meter 1. However, the present invention is not limited to this, and a wireless communication method other than Bluetooth can be used.

  The PC 6 is installed with application software 7 for controlling the power meter 1 and storing and managing the received power data, and performs processing such as collection and display of the power data measured by the power meter 1.

  The power data is stored in the power data DB 82 on the server 8 connected to the plurality of PCs 6 a and 6 b via the Internet 9 and managed by the server 8. Similarly, a setting file 81 in which information (hereinafter also referred to as “connection relation information”) indicating connection relations of a plurality of power meters 1a, 1b, 1c, and 1d is stored in the server 8 and managed. The connection relation information includes information indicating which power meter 1a, 1b, 1c, 1d the PC 6a, 6b acquires measurement data measured by the plurality of power meters 1a, 1b, 1c, 1d. . The setting file may include not only connection information but also information related to the electrical product 3 to be measured.

  In this way, the setting file and power data are stored in the server 8.

  For example, when a power meter 1 that measures a new electrical product 3 is added and connected to the network group NW, or when a PC 6 for referring to and browsing power data is added and connected, the power meters 1 are connected to each other. A configuration file that stores relationship information may be required. In this case, there is a method of referring to the setting file via a medium such as a USB (Universal Serial Bus) memory or a connected network. However, if the setting file storage location information indicating the storage location of the setting file is not accurately known, there is a problem that a device to be added cannot be immediately connected to the network group NW.

  In general, in wireless communication such as Bluetooth, there are radio wave shields, and it is not always possible to access all the power meters 1a, 1b, 1c, and 1d directly from the PC 6a and the PC 6b. Therefore, an example of a search method for searching for the connection relationship of the power meter 1 will be described. For example, when the PC 6a shown in FIG. 3 searches for the connection relationship of the plurality of power meters 1 belonging to the network group NW, first, the power meter 1a to which the PC 6a can be directly connected is directed according to the instruction of the application software 7 that is started on the PC 6a. Explore. Next, the PC 6a uses the searched power meter 1a as a wireless connection relay station to find other accessible power meters 1b and 1c. Next, the PC 6a finds an accessible power meter 1d using the power meters 1b and 1c in addition to the power meter 1a as a wireless connection relay station.

  Thereby, the search for the access path between the power meters 1 is completed. Route information indicating the completed access path and parent information indicating the parent-child relationship of devices between the power meters 1 are stored in the setting file. For example, in the above example, the parent information of the setting file stores information indicating that the power meter 1a directly connected to the PC 6a is a parent device, the power meters 1c and 1b are child devices, and the power meter 1d is a grandchild device. The For example, the route information of the setting file stores information indicating the route of the power meter 1a → the power meter 1c → the power meter 1d and the route of the power meter 1a → the power meter 1b. In such a relay operation between the power meters 1, each of the power meters 1a and 1c has no more function as a relay station.

  Moreover, each electric power meter 1 does not record mutual connection relationship information. In addition, each ROM 12 of the power meters 1a, 1b, 1c, and 1d has a storage area for storing information on the storage location of the information indicating the connection relationship (setting file storage location information 31), but stores the connection relationship information itself. There is no storage area.

  Therefore, the power meter 1 according to the present embodiment stores the storage location information 31 of the setting file in the ROMs 12 of all the power meters 1 belonging to the network group NW. Thereby, when adding the PC 6, the setting file storage location information 31 stored in the ROM 12 of any one of the power meters 1 is received and the received setting regardless of which power meter 1 establishes the connection with the added PC. A setting file 81 stored in the server 8 can be referred to based on the file storage location information 31. As a result, the added PC does not need to acquire information indicating the connection relation of the plurality of power meters 1 belonging to the network group NW in advance, and storage location information of the information indicating the connection relation can be obtained in advance. The connection information of the power meter 1 can be grasped.

[Functional configuration of power meter]
Next, an example of a functional configuration of the power meter 1 according to the present embodiment will be described with reference to FIG. The power meter 1 includes a data measurement unit 21, a recording unit 22, a control unit 23, and a communication control unit 24.

  The data measuring unit 21 measures power, temperature, humidity, and illuminance and records them in the recording unit 22.

  The communication control unit 24 transmits / receives various data of the recording unit 22, setting files, setting file storage location information, and the like according to control of Bluetooth communication and instructions of this communication.

  The recording unit 22 stores various measured data, storage location information of setting files, and the like. The recording unit 22 records the acquired information in the ROM 12 as setting file storage location information 31. The control unit 23 performs overall control of these units. The function of the control unit 23 is realized by the microcomputer 11. The function of the data measurement unit 21 is realized by the microcomputer 11, the power measurement circuit 13, and the temperature / humidity / illuminance measurement circuit 14. The function of the communication control unit 24 is realized by the microcomputer 1 and the wireless circuit 15.

  The recording unit 22 records a power data DB 32, a temperature / humidity / illuminance data DB 33, and a connection relationship recording program 34 in addition to the setting file storage location information 31. The function of the recording unit 22 is realized by the ROM 12, for example.

  The setting file storage location information 31 indicates the storage location of information such as the connection relationship of the power meter 1. For example, the setting file storage location information 31 indicates a storage location (address) where the setting file 81 of the server 8 in FIG. 3 is recorded.

Note that FIG. 4 is a block diagram focusing on functions, and each unit indicated by these functional blocks can be realized by hardware alone, software alone, or a combination of hardware and software.
(setting file)
Information stored in the setting file recorded in the storage location indicated by the setting file storage location information 31 on the server 8 is shown below.

Connection information when multiple power meters 1 are set as one network group NW Storage location of power data, etc. Installation location of each power meter 1 in the network group NW Each power meter in the network group NW Information of electrical product 3 connected to 1 Information of PC 6 that refers to each power meter 1 in network group NW The above connection information includes parent information indicating a parent-child relationship of a plurality of power meters 1 and a plurality of information Route information indicating the access path of the power meter 1 may be included.

[Connection record processing]
Next, the connection relationship recording process according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing an example of the connection relation recording process according to the present embodiment. This process is executed by the control unit 23.

  When this processing is started, first, as initialization processing, initialization of the microcomputer 11, communication settings, and storage of the setting file storage location information 31 in the ROM 12 are performed (step S11). The initialization process will be described later with reference to FIG. When the initialization process ends, the microcomputer 11 uses the power measurement circuit 13 to start measuring power (step S12). Next, the microcomputer 11 determines whether or not there is a transmission request for power data from the PC 6 (step S13).

  If the microcomputer 11 determines that there is a power data transmission request from the PC 6, the microcomputer 11 transmits the power data stored in the power data DB 32 of the ROM 12 to the PC 6 (step S14). After transmitting the power data to the PC 6 or when it is determined in step S13 that there is no transmission request for power data from the PC 6, the microcomputer 11 determines whether there is a transmission request for setting file storage location information from the PC 6. (Step S15).

  If the microcomputer 11 determines that there is a transmission request for the storage location information of the setting file 81 from the PC 6, it transmits the setting file storage location information 31 stored in the ROM 12 to the PC 6 (step S16).

  After transmitting the setting file storage location information 31 to the PC 6 or when it is determined in step S15 that there is no request for transmission of the storage location information of the setting file 81 from the PC 6, the microcomputer 11 issues a power data measurement stop request from the PC 6. It is determined whether or not there is (step S17). If the microcomputer 11 determines that there is no power data measurement stop request from the PC 6, the microcomputer 11 returns to step S <b> 12 and executes the processes after step S <b> 12. If it is determined in step S17 that there is a power data measurement stop request from the PC 6, this process is terminated.

  In this process, power data is measured. However, in the connection relationship recording process according to the present embodiment, temperature data measured by the temperature / humidity / illuminance measurement circuit 14 instead of or together with power data. The humidity data and the illuminance data may be transmitted to the PC 6.

(Initialization process)
The initialization process in step S11 of FIG. 5 will be specifically described with reference to FIG. 6 is a flowchart showing an example of an initialization process mainly executed by the CPU of the PC 6, and an initialization process mainly executed by the microcomputer 11 of the power meter 1 is shown in the right dotted line frame. It is a flowchart which shows an example.

  First, the PC 6 secures a storage area for storing power data and setting files on the server 8 (step S21). Thereby, as shown in FIG. 7, an area for storing the setting file 81 and an area for storing the power data DB 82 are set on the server 8.

  Next, the PC 6 sets wireless communication (Bluetooth) with the power meter 1 (step S22). In response to this, the power meter 1 performs setting (pairing processing) for wireless communication with the PC 6 (step S23). When Bluetooth is used for wireless communication, pairing between the power meter 1 and the PC 6 corresponds to this communication setting.

  The pairing process is performed by inserting the power meter 1 into an outlet near the PC 6. After the pairing of the power meter 1 and the PC 6 is completed, the power meter 1 is moved to the outlet of the electrical product 3 to be measured, and measurement of power data is started. By pairing the power meter 1 and the PC 6 and specifying the connection partner device, it is not possible to connect from other PCs 6 equipped with neighboring Bluetooth, and data leakage that causes security problems is prevented. be able to.

  When the power meter 1 notifies the completion of the wireless communication setting (pairing process), the PC 6 issues a search and connection instruction for another power meter 1 (step S24). In response to this, the power meter 1 searches for another power meter 1, and when another power meter 1 is found, connection setting (connection processing) is performed (step S25).

  When the power meter 1 notifies the completion of the search and connection processing of another power meter, the PC 6 receives the information and creates a setting file (step S26), and stores the created setting file in the server 8 (step S26). S27). Next, the PC 6 transmits the storage location information of the setting file to the power meter 1 (step S28). The power meter 1 stores the received setting file storage location information in the ROM 12 as the setting file storage location information 31 (step S29), and ends the initialization process.

[When a PC is added]
A case where a new PC is added to the measurement system 10 shown in FIG. 3 will be described. FIG. 7 shows a state in which a PC 6c is newly added to the measurement system 10 shown in FIG. When adding the PC 6c, if the location of the setting file 81 is not known, there arises a problem that the PC 6c cannot collect and display the power data of each power meter 1.

  Here, as described above, each of the ROMs 12 of the power meters 1a, 1b, 1c, and 1d has a storage area for storing information on the storage location of the information indicating the connection relationship (setting file storage location information 31). There is no storage area for storing the relationship information itself.

  Further, when a plurality of power meters 1 and a plurality of PCs 6 are connected, the file size of the setting file 81 becomes large. In addition, the file size of the setting file 81 is frequently changed by adding or deleting the power meter 1 or the PC 6. Therefore, it is difficult to store the information in the setting file 81 in the power meter 1. For this reason, it is effective to store the setting file 81 on the server 8 and save the setting file storage location information (that is, the setting file storage location information 31) in the power meter 1.

  Therefore, the total power meter 1 in the network group NW of the present embodiment solves the above problem by recording the setting file storage location information 31 in the ROM 12. That is, the added PC 6c determines the storage location of the setting file 81 based on the setting file storage location information 31 recorded in the ROM 12 of the connectable power meter 1. Then, the PC 6 c receives from the server 8 connection relation information stored in the determined storage location of the setting file 81. Thereby, the new PC 6c can grasp the connection relationship of the power meters 1a, 1b, 1c, and 1d belonging to the network group NW. Thus, the new PC 6c can immediately collect power data and the like from each power meter 1 belonging to the network group NW.

  In FIG. 7, the power meter 1a and the power meter 1c are directly connected via Bluetooth 5a. The power meter 1d that is not directly connected to the power meter 1a can be connected to the power meter 1a via the power meter 1c. Similarly, the power meter 1b that is not directly connected to the power meter 1c can be connected to the power meter 1c via the power meter 1b that is directly connected to the power meters 1b and 1c and Bluetooth 5d and 5a. The PC 6a and the PC 6b establish connection with the power meters 1a to 1d by obtaining connection relation information of the power meters 1a to 1d, and obtain power data stored in the ROMs 12 of the connected power meters 1. Can do.

  An operation when the PC 6c is added to the measurement system 10 having such a configuration will be described. Although the PC 6c is already connected to the Internet 9, it does not have the storage location information of the setting file 81 and the storage location information of the power data DB 82. Therefore, the PC 6c first pairs with a nearby power meter 1d to establish a Bluetooth 5f connection. In this state, the PC 6c does not yet have information such as which electric product 3 the power meter 1d measures the power of and how it is connected to the other power meters 1a to 1c.

  Therefore, the PC 6c refers to the setting file storage location information 31 stored in the ROM 12 of the power meter 1d and reads the setting file 81 from the server 8. Thereby, the connection state of the electric power meters 1a to 1d and the information on the electric products 3 that are measured by the electric power meters 1a to 1d can be obtained.

[Recording of connection relationship when a PC is added]
The connection relation recording process when the PC 6 according to this embodiment described above is added will be described with reference to FIG. When this process is started, the PC 6 sets wireless communication (Bluetooth) with the power meter 1 that the user operating the PC 6 wants to refer to (step S31). In response to this, the power meter 1 performs setting (pairing processing) of wireless communication with the PC 6 (step S32).

  When the power meter 1 notifies the completion of the wireless communication setting (pairing process), the PC 6 requests transmission of setting file storage location information recorded in the ROM 12 of the power meter 1 (step S33). In response to this, the power meter transmits the setting file storage location information 31 stored in the ROM 12 (step S34).

  The PC 6 reads the setting file 81 from the server 8 based on the received setting file storage location information 31 (step S35). Next, the PC 6 sets the setting information (including connection relation information) of the power meter 1 and the storage location information of the power data in the application software 7 according to the contents of the setting file 81 (step S36). The PC 6 adds the information of the last added PC 6 to the setting file 81, updates the setting file 81 on the server 8 (step S37), and ends this process.

  As described above, according to the measurement system 10 according to the present embodiment, each power meter 1 receives the storage location information of the connection relation information of the plurality of power meters 1 belonging to the network group NW and saves it in the ROM 12 of each power meter 1. To do. As described above, according to the measurement system 10 according to the present embodiment, the storage location information of the connection relation information of the plurality of power meters 1 is recorded in each power meter 1 that can be referred to from the PC 6. Thereby, the PC 6 added to the network group NW extracts the storage location information of the connection relation information from any connected power meter 1, and refers to the setting file 81 at the storage location indicated by the storage location information. can do. In this way, the added PC 6 can acquire information indicating the connection relationship of the power meters 1 belonging to the network group NW without having to previously acquire storage location information of the information indicating the connection relationship.

  In the measurement system 10 shown in FIG. 7, the connection relationship information includes Bluetooth 5a to 5f indicating the connection relationship between the power meters 1a to 1d and the PCs 6a to 6c, information indicating the parent-child relationship between the power meters 1a to 1d, and the PC 6a. -6c includes information on a route path when connecting to at least one of the power meters 1a-1d.

  In the present embodiment, an example in which the power meter 1 measures power data has been described. However, temperature data, humidity data, and illuminance data may be measured instead of the power data or together with the power data. Temperature data, humidity data, and illuminance data are detected at predetermined time intervals by a temperature sensor, a humidity sensor, and an illuminance sensor installed in the power meter 1. The temperature sensor, humidity sensor, and illuminance sensor measured by the power meter 1 are temporarily stored in the temperature / humidity / illuminance data DB 33 and stored on the server 8 as appropriate.

(Other examples)
The plurality of devices belonging to the same network group NW are not limited to the power meter 1. For example, a BD recorder is taken as another example of a plurality of devices belonging to the network group NW. In the operation of storing the recording data in a server installed in the home, when connecting a plurality of BD recorders for the purpose of simultaneously recording a plurality of channels, the connection setting file is stored on the server 8, and in the BD recorder, Stores configuration file storage location information.

  The BD recorder to be added later reads the storage location information of the setting file from the previously connected BD recorder, and reads the configuration file on the server recorded in the storage location indicated by the storage location information of the configuration file, The wireless connection can be set immediately. Also, when connecting to a BD recorder in the operation of browsing recorded data on the PC 6, the storage location information of the stored setting file is read and recorded on the storage location indicated by the storage location information of the setting file. By reading the setting file, wireless connection can be set immediately.

  It is also conceivable that the setting file is stored in a predetermined storage location of the recording device on the cloud, the storage location information is notified to the PC 6, and the PC 6 refers to the setting file. Alternatively, it is conceivable that the PC 6 refers to the setting file when an application on the cloud executes access to the setting file. However, with the measurement system 10 according to the present embodiment, it is not necessary to know the storage location of such an application.
