DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, embodiments of the setting system according to the present invention will be described in detail with reference to the drawings. Note that each of the embodiments described below represents a preferred specific example of the present invention. The numerical values, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, components not recited in the independent claims will be described as optional components constituting a preferred embodiment.

[0015] It should be noted that the drawings are schematic diagrams and are not necessarily strict illustrations. In addition, in the drawings, substantially the same components are denoted by the same reference numerals, and overlapping descriptions may be omitted or simplified.

[0016] (Embodiment) 1 is a diagram illustrating a situation in which a setting system 10 according to an embodiment is applied. Here, a manner in which an installer sets up a measuring device 70 using a terminal device 20 is described. The terminal device 20 can obtain information necessary for setting up the measuring device 70 by reading the unit two-dimensional code 31 and the sensor two-dimensional code 41, which are respectively assigned to the measuring unit 30 and the current sensor 40 associated with the measuring device 70, or by communicating with a server 50.

[0017] [composition] First, the configuration of the setting system according to the embodiment will be described below. Fig. 2 is a block diagram showing the functional configuration of the setting system according to the embodiment.

[0018] 2, the setting system 10 includes a terminal device 20, a server 50, and a distribution board 100. The setting system 10 is a system for correctly setting the circuit method and the like in a measuring device 70 installed in the distribution board 100 using the terminal device 20 that communicates with the server 50.

[0019] The distribution board 100 is installed in, for example, a detached house. The distribution board 100 may also be installed in any facility where it can be installed, such as each dwelling unit in an apartment building, an office, a store, a factory, a hospital, or the like.

[0020] The measuring device 70 is a device for measuring the power and amount of power of the current flowing through the distribution board. The measuring device 70 includes, for example, the measuring unit 30 and the current sensor 40.

[0021] The configuration of the devices included in the setting system 10 will be described below.

[0022] The terminal device 20 is, for example, an information terminal device such as a smartphone or tablet terminal used by a user. The user of the terminal device 20 is, for example, a contractor who installs the measuring device 70 in the distribution board 100. The user can use the terminal device 20 to perform setting work when installing the measuring device 70 in the distribution board 100. Specifically, the terminal device 20 includes a communication unit 21, an information processing unit 22, a memory unit 23, a display unit 24, an operation reception unit 25, an imaging unit 26, and a local communication unit 27.

[0023] The communication unit 21 is a communication circuit (communication module) that enables the terminal device 20 to communicate with the server 50 via the public network 60. The communication performed by the communication unit 21 is, for example, wireless communication. There are no particular limitations on the communication standard of the communication performed by the communication unit 21.

[0024] The information processing unit 22 performs information processing to allow a user to install the measuring device 70 on the distribution board 100 using the terminal device 20. The information processing unit 22 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit. The functions of the information processing unit 22 are realized by the microcomputer or processor constituting the information processing unit 22 executing a computer program stored in the storage unit 23. Specifically, the information processing unit 22 includes an acquisition unit 22a, an output unit 22b, a determination unit 22c, a display control unit 22d, and a notification unit 22e.

[0025] The acquisition unit 22a acquires first specification information from the server 50 by communicating with the server 50 based on first information obtained by capturing an image of the unit two-dimensional code 31 assigned to the measurement unit 30 with the imaging unit. Furthermore, the acquisition unit 22a acquires second specification information obtained by capturing an image of the sensor two-dimensional code 41 assigned to the current sensor 40 with the imaging unit. The acquisition unit 22a may also acquire the second specification information from the server 50 by communicating with the server 50 based on second information obtained by capturing an image of the sensor two-dimensional code 41 assigned to the current sensor 40 with the imaging unit.

[0026] The output unit 22b outputs setting instruction information for reflecting the settings made through the setting screen in the measurement unit 30.

[0027] The determination unit 22c determines whether the specifications of the current sensors 40 attached to each of the multiple circuits are appropriate based on the second specification information and the setting contents. Furthermore, after the setting of the measuring device 70, the determination unit 22c determines whether the attachment direction of the current sensors 40 is correct based on an image showing the attachment state of the current sensors 40 captured by the imaging unit.

[0028] The display control unit 22d controls the display of a setting screen for making settings related to the measuring unit 30 on the display unit 24 based on the first specification information acquired by the acquisition unit 22a.

[0029] When the determining unit 22c determines that the specifications of the current sensor 40 are not appropriate, the notifying unit 22e notifies the installer of this fact.

[0030] The storage unit 23 is a storage device that stores computer programs and the like executed by the information processing unit 22. The computer programs stored in the storage unit 23 include a predetermined application program for setting a circuit system and the like in the measuring device 70. The storage unit 23 is realized by, for example, a semiconductor memory.

[0031] The display unit 24 displays an image for setting the measurement device 70. The display unit 24 is realized by a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence) panel, for example.

[0032] The operation reception unit 25 receives operations from the user and is realized by, for example, a touch panel.

[0033] The imaging unit 26 captures an image of the two-dimensional code provided on the measuring device 70. The imaging unit 26 is realized by, for example, a camera.

[0034] The local communication unit 27 is a communication circuit (communication module) that enables the terminal device 20 to communicate with the measurement unit 30 via a local network. The local communication unit 27 performs wired communication with the measurement unit 30, such as USB communication, but may also perform short-range wireless communication with the measurement unit 30, such as BLE.

[0035] The measurement unit 30 is a power meter and a watt-hour meter. The measurement unit 30 is installed in the distribution board 100, and measures or records the power and energy used in a detached house or the like in which the distribution board 100 is installed. Specifically, the measurement unit 30 measures or records the power and energy by converting the current value obtained from the current sensor 40 into an actual current value. Specifically, the measurement unit 30 includes a unit two-dimensional code 31, a memory unit 32, and a communication unit 33.

[0036] The unit two-dimensional code 31 is a two-dimensional code assigned to the measurement unit 30. The unit two-dimensional code 31 includes URL information of a site that stores specification information used when setting up the measurement unit 30, such as information on the number of circuits in the measurement unit 30 and the type of measurement.

[0037] The storage unit 32 stores the measurement values ​​of power and energy and setting information indicating the current settings of the measurement unit 30. Note that the measurement values ​​of power and energy may also be stored in another unit connected to the measurement unit 30. The storage unit 32 is realized by, for example, a semiconductor memory.

[0038] The communication unit 33 is a communication circuit (communication module) for the measurement unit 30 to communicate with the terminal device 20. The communication performed by the communication unit 33 is, for example, wired communication, but may also be wireless communication. The communication standard of the communication performed by the communication unit 33 is not particularly limited.

[0039] The current sensor 40 is a CT (Current Transformer) that converts the actual current value of the current flowing in a circuit (branch circuit) connected to the distribution board 100 into a smaller current value. One or more current sensors 40 are provided in the measurement unit 30. A sensor two-dimensional code 41 indicating the specifications of the current sensor 40 is attached to the current sensor 40. The specifications of the current sensor 40 are, for example, rated information of the current sensor 40.

[0040] The server 50 is, for example, one or more servers located outside the distribution board 100. The server 50 is a server that stores information of the measuring device 70. The server 50 can communicate with the terminal device 20 via a public network 60 such as the Internet. Specifically, the server 50 includes a server communication unit 51, an information processing unit 52, and a storage unit 53.

[0041] The server communication unit 51 is a communication circuit (communication module) that enables the server 50 to communicate with the terminal device 20 via the public network 60. The communication performed by the server communication unit 51 is, for example, wireless communication. The communication standard of the communication performed by the server communication unit 51 is not particularly limited.

[0042] The information processing unit 52 may perform information processing for a user to install the measuring device 70 in the distribution board 100 using a terminal device 20 that communicates with the server 50. The information processing unit 52 is realized, for example, by a microcomputer, but may also be realized by a processor or a dedicated circuit. The functions of the information processing unit 52 are realized by the microcomputer or processor constituting the information processing unit 52 executing a computer program stored in the storage unit 53. Specifically, the information processing unit 52 includes an acquisition unit 52a that acquires specification information of the measuring device 70, an output unit 52b that outputs the specification information to the terminal device 20, and a determination unit 52c that determines whether the current sensor 40 is appropriate and whether it has been properly installed.

[0043] The storage unit 53 is a storage device that stores specification information of the measurement unit 30 used to set the measurement device 70, a computer program executed by the information processing unit 52, and the like. The storage unit 53 may also store specification information of the current sensor 40. The storage unit 53 may also store the installation status of the set measurement device 70. The storage unit 53 is realized by, for example, a semiconductor memory.

[0044] [Example 1: Operation during setup] Next, the operation of the setting system 10 according to the embodiment will be described. When installing the measuring device 70 in the distribution board 100, it is necessary to set the circuit method for each circuit, and since there are many setting items, it is easy to make a setting mistake, or it may happen that a setting mistake goes unnoticed.

[0045] In response to this, the setting system 10 can display a setting screen for setting the measuring device 70 on the terminal device 20. This allows the installer to more easily set up the measuring device 70. Below, a first operational example of such a setting system 10 will be described. Figure 3 is a flowchart showing the first operational example of the setting system 10 according to the embodiment.

[0046] First, the acquisition unit 22a acquires first information from the measurement unit 30 by capturing an image of the unit two-dimensional code 31 attached to the measurement unit 30 using the imaging unit 26 (S11 in FIG. 3). The first information is, for example, a URL of a site that stores information about the measurement unit 30.

[0047] When the acquiring unit 22a acquires the first information, the acquiring unit 22a communicates with the server 50 using the communication unit 21 based on the acquired first information, and acquires first specification information of the measuring unit 30 (S12 in FIG. 3). The acquiring unit 22a transmits the first information to the information processing unit 52 of the server 50 via the communication unit 21, the public network 60, and the server communication unit 51. Based on the acquired first information, the information processing unit 52 acquires corresponding first specification information stored in the storage unit 53, and transmits the first specification information to the acquiring unit 22a via the server communication unit 51, the public network 60, and the communication unit 21. Here, the first specification information includes information necessary for setting up the measuring device 70, such as the number of circuits in the measuring unit 30.

[0048] When the acquiring unit 22a acquires the first specification information, the display control unit 22d displays a setting screen for setting the measurement device 70 on the display unit 24 based on the acquired first specification information (S13 in FIG. 3). The display unit 24 automatically displays a setting screen including, for example, setting areas (setting UIs) for each circuit, the same number of which is the same as the number of circuits in the measurement unit 30 indicated by the first specification information.

[0049] After displaying the setting screen on the display unit 24, the information processing unit 22 accepts setting operations by the installer via the operation accepting unit 25 (S14 in FIG. 3). The installer sets up the measuring device 70 according to the setting screen displayed on the display unit 24. The setting operations performed by the installer include, for example, an operation to select a circuit to which the current sensor 40 is to be attached and an operation to specify the rated current flowing through the circuit.

[0050] Finally, the output unit 22b outputs setting instruction information to the measurement unit 30 using the local communication unit 27 based on the setting operation performed by the installer (S15 in FIG. 3).

[0051] In this way, according to the first operational example, the installer can configure the measuring device 70 using the terminal device 20.

[0052] [Operation Example 2: Operation 1 for Determining Whether the Specifications of the Current Sensor 40 are Appropriate] The terminal device 20 can obtain second specification information of the current sensor 40 to be attached to the circuit by reading the sensor two-dimensional code 41 using the imaging unit 26. In this case, the terminal device 20 can determine from the obtained second specification information whether the current sensor 40 to be installed is appropriate based on the first specification information obtained in S12 of Fig. 3. A second operation example of such a setting system 10 will now be described. Fig. 4 is a flowchart showing the second operation example of the setting system 10 according to the embodiment.

[0053] After the output unit 22b outputs the setting instruction information to the measurement unit 30 as shown in S15 of Fig. 3, the acquisition unit 22a acquires the second specification information by capturing an image of the sensor two-dimensional code 41 attached to the current sensor 40 to be installed using the imaging unit 26 (S21 of Fig. 4). The second specification information is, for example, information indicating the rating of the current sensor 40.

[0054] When the acquisition unit 22a acquires the second specification information, the determination unit 22c checks the second specification information based on the first specification information to determine whether the current sensor 40 to be installed is appropriate (S22 in FIG. 4). The current sensor 40 being appropriate means that the rating of the current sensor 40 is suitable for the circuit in which it is installed. When the circuit type is a single-phase two-wire system, a single-phase three-wire system, or a three-phase three-wire system, the rating of the current sensor 40 installed in the R layer must match the rating of the current sensor 40 installed in the T layer. In this case, the current sensor 40 being appropriate means that the rating of the current sensor 40 installed in the R layer must match the rating of the current sensor 40 installed in the T layer. Furthermore, when the circuit type is a three-phase four-wire system, the rating of the current sensor 40 installed in the R phase must match the rating of the current sensor 40 installed in the S phase and the rating of the current sensor 40 installed in the T phase. In this case, an appropriate current sensor means that the ratings of the current sensor 40 installed in the R phase, the current sensor 40 installed in the S phase, and the current sensor 40 installed in the T phase are the same.

[0055] If the determination unit 22c determines that the current sensor 40 is inappropriate (No in S23 of FIG. 4), the notification unit 22e notifies the installer that the current sensor 40 to be installed is inappropriate (S24 of FIG. 4). At this time, the notification unit 22e uses, for example, the display control unit 22d to display on the display unit 24 a screen warning that the current sensor 40 is inappropriate. Here, the notification method is not particularly limited.

[0056] After being notified that the current sensor 40 is inappropriate, the installer changes the current sensor 40 to an appropriate one (S25 in FIG. 4). Thereafter, the installer repeats the operations of S21 to S25 until the determination unit 22c determines that the current sensor 40 is appropriate (Yes in S23 in FIG. 4).

[0057] If the determining unit 22c determines that the current sensor 40 is appropriate (Yes in S23 in FIG. 4), the installer installs the current sensor 40 in the circuit (S26 in FIG. 4).

[0058] Thus, according to Operation Example 2, the terminal device 20 can determine whether the current sensor 40 to be installed is appropriate. In other words, it is possible to prevent the installer from installing the wrong current sensor 40.

[0059] In the second operational example, the second specification information of the current sensor 40 is acquired after step S15 in Fig. 3, but it may be acquired before the start of the construction work, or may be acquired at any step from steps S11 to S14 in Fig. 3. The second specification information of the current sensor 40 may be acquired at any time before the current sensor 40 is installed.

[0060] [Operation Example 3: Operation 2 for Determining Whether the Specifications of the Current Sensor 40 are Appropriate] The determination of whether the specifications of the current sensor 40 to be installed are appropriate may be performed by the server 50, rather than by the terminal device 20. A third operational example of such a setting system 10 will now be described. Figure 5 is a sequence diagram showing a third operational example of the setting system 10 according to the embodiment.

[0061] After the output unit 22b outputs the setting instruction information to the measurement unit 30 as shown in S15 of Figure 3, the acquisition unit 22a acquires the second specification information by using the imaging unit 26 to capture an image of the sensor two-dimensional code 41 attached to the current sensor 40 to be installed (S31 of Figure 5).

[0062] When the acquisition unit 22a acquires the second specification information, the information processing unit 22 transmits the second specification information to the server 50 using the communication unit 21 (S32 in FIG. 5). The second specification information transmitted by the communication unit 21 is received by the server 50 via the public network 60.

[0063] When the second specification information is received, the determining unit 52c checks the second specification information based on the first specification information and determines whether the current sensor 40 to be installed is appropriate (S33 in FIG. 5).

[0064] The output unit 52b transmits the determination result to the terminal device 20 using the server communication unit 51 (S34 in FIG. 5). The determination result transmitted by the server communication unit 51 is received by the terminal device 20 via the public network 60.

[0065] If the determination unit 52c determines that the current sensor 40 is inappropriate, the notification unit 22e notifies the installer that the current sensor 40 to be installed is inappropriate. At this time, the notification unit 22e uses, for example, the display control unit 22d to display a screen on the display unit 24 warning that the current sensor 40 is inappropriate. Here, the notification method is not particularly limited.

[0066] After being notified that the current sensor 40 is inappropriate, the installer changes the current sensor 40 to an appropriate one. Thereafter, the installer repeats the operations of S31 to S34 until the determination unit 52c determines that the current sensor 40 is appropriate.

[0067] If the determining unit 52c determines that the current sensor 40 is appropriate, the installer installs the current sensor 40 in the circuit (S35 in FIG. 5).

[0068] In this way, the server 50 can determine whether the current sensor 40 to be installed is appropriate, which means that it is possible to prevent the installer from installing the wrong current sensor 40.

[0069] In the third operational example, the second specification information of the current sensor 40 is acquired after step S15 in Fig. 3, but it may be acquired before the start of the construction work, or may be acquired at any step from steps S11 to S14 in Fig. 3. The second specification information of the current sensor 40 may be acquired at any time before the current sensor 40 is installed.

[0070] [Operation Example 4: Operation 1 for determining whether the installation direction of the current sensor 40 is appropriate] The current sensor 40 must be installed in the correct orientation. However, it is not possible to check whether it is installed in the correct orientation until power is applied. Therefore, there is a problem in that it may not be noticed if it is installed in the wrong orientation.

[0071] In response to this, the setting system 10 can determine whether the current sensor 40 is installed in the appropriate direction by capturing an image of the installation status after the current sensor 40 is installed and analyzing the captured image. A fourth operational example of such a setting system 10 will now be described. Figure 6 is a flowchart illustrating a fourth operational example of the setting system 10 according to the embodiment.

[0072] As shown in S15 of FIG. 3, after the output unit 22b outputs setting instruction information to the measurement unit 30 based on the setting operation performed by the installer, the installer uses the imaging unit 26 to capture an image of the measurement device 70 that has been set up. Therefore, the information processing unit 22 acquires an image showing the installation status of the measurement unit 30 and the current sensor 40 (S41 of FIG. 6). FIG. 7 is a schematic diagram showing a correct installation status. As shown in FIG. 7, the correct installation status is when the current sensor 40 is attached in a predetermined orientation to one of the two electric wires connecting the breaker and the load. In this case, if the image acquired in step S41 shows the breaker, load, current sensor 40, and two electric wires, it can be determined from this image whether the current sensor 40 is installed correctly as shown in FIG. 7.

[0073] Whether the installation direction is appropriate can be determined based on the text information attached to the current sensor 40. When an image showing the installation situation is acquired, the information processing unit 22 extracts text information indicating the installation direction of the current sensor 40 from the image (S42 in FIG. 6). The extracted text information is text information indicating the power supply side and text information indicating the load side attached to the current sensor 40. For example, in FIG. 7, the text information is "L←K," where K is the text information indicating the power supply side (breaker side) and L is the text information indicating the load side, but the text information is not particularly limited.

[0074] When the information processing unit 22 extracts the character information, the determination unit 22c determines whether the installation direction of the current sensor 40 is appropriate based on the extracted character information (S43 in FIG. 6). If the current sensor 40 is installed so that the characters indicating the power supply side are on the power supply side and the characters indicating the load side are on the load side, the current sensor 40 is installed in the appropriate orientation. Which side of the circuit (electric wire) is on the power supply side and which side is on the load side can be identified, for example, by the arrangement of other components shown in the image or other characters shown in the image.

[0075] If the determination unit 22c determines that the installation direction of the current sensor 40 is inappropriate (No in S44 of FIG. 6), the notification unit 22e notifies the installer that the installation direction of the installed current sensor 40 is inappropriate (S45 of FIG. 6). At this time, the notification unit 22e displays, for example, a screen on the display unit 24 warning that the installation direction of the current sensor 40 is inappropriate. Here, the method of notification is not particularly limited.

[0076] After being notified that the installation direction of current sensor 40 is inappropriate, the installer changes the installation direction of current sensor 40 to an appropriate one (S46 in FIG. 6). Here, after the installation direction of current sensor 40 is changed, whether the installation direction is appropriate may be determined by repeating the steps of S41 to S43 in FIG. 6.

[0077] If the determining unit 22c determines that the installation direction of the current sensor 40 is appropriate (Yes in S44 of FIG. 6), the installer determines that the setting of the measurement device 70 has been performed appropriately.

[0078] Thus, according to Operation Example 4, terminal device 20 can determine whether the installation direction of installed current sensor 40 is appropriate. In other words, if the installer installs current sensor 40 in an incorrect installation direction, it can be corrected.

[0079] [Operation Example 5: Operation 2 for Determining Whether the Mounting Direction of the Current Sensor 40 is Appropriate] The determination of whether the installation direction of the current sensor 40 is appropriate may be performed by the server 50, rather than by the terminal device 20. A fifth operational example of such a setting system 10 will now be described. Fig. 8 is a sequence diagram showing the fifth operational example of the setting system 10 according to the embodiment.

[0080] 3, after the output unit 22b outputs setting instruction information to the measurement unit 30 based on the setting operation performed by the installer, the installer captures an image of the set measurement device 70 using the imaging unit 26. Therefore, the information processing unit 22 acquires an image showing the installation status of the measurement unit 30 and the current sensor 40 (S51 in FIG. 8).

[0081] When the image showing the construction status is acquired, the information processing unit 22 uses the communication unit 21 to transmit the image showing the construction status to the server 50 (S52 in FIG. 8). The image transmitted by the communication unit 21 is received by the server 50 via the public network 60.

[0082] When the image is received, the information processing unit 52 extracts text information indicating the installation direction of the current sensor 40 from the image (S53 in FIG. 8). Next, the determination unit 22c determines whether the installation direction of the current sensor 40 is appropriate based on the extracted text information (S54 in FIG. 8).

[0083] The output unit 52b transmits the determination result to the terminal device 20 using the server communication unit 51 (S55 in FIG. 5). The determination result transmitted by the server communication unit 51 is received by the terminal device 20 via the public network 60.

[0084] If the determination unit 52c determines that the installation direction of the current sensor 40 is inappropriate, the notification unit 22e notifies the installer that the installation direction of the installed current sensor 40 is inappropriate. At this time, the notification unit 22e uses, for example, the display control unit 22d to display on the display unit 24 a screen warning that the installation direction of the current sensor 40 is inappropriate. Here, the method of notification is not particularly limited.

[0085] After being notified that the installation direction of current sensor 40 is inappropriate, the installer changes the installation direction of current sensor 40 to an appropriate one. Here, after the installation direction of current sensor 40 is changed, whether the installation direction is appropriate may be determined by repeating the steps S51 to S54 in FIG. 8.

[0086] If the determining unit 22c determines that the installation direction of the current sensor 40 is appropriate, the installer determines that the setting of the measurement device 70 has been performed appropriately.

[0087] Thus, according to Operation Example 5, the server 50 can determine whether the installation direction of the installed current sensor 40 is appropriate. In other words, if the installer installs the current sensor 40 in an incorrect installation direction, the installation direction can be corrected.

[0088] In the fifth operational example, an image showing the construction status can be saved in the server 50, and the image can be referenced later.

[0089] This makes it possible to check the status of construction through images, making maintenance easier.

[0090] [Modification of two-dimensional code] In the above embodiment, it has been described that the distribution board 100 is provided with one measurement unit 30. In cases where the distribution board 100 has a large number of circuits and one measurement unit 30 cannot measure the current of all the circuits, the number of circuits that can be measured by the measurement unit 30 can be increased by adding a unit for adding circuits to the distribution board 100.

[0091] When a measurement unit 30 and an expansion unit are provided in the distribution board 100, the unit two-dimensional code 31 may be assigned to each of the measurement unit 30 and the expansion unit, or the measurement unit 30 may be assigned a unit two-dimensional code 31 indicating the combined specifications of the measurement unit 30 and the expansion unit.

[0092] Furthermore, the unit two-dimensional code 31 of the measurement unit 30 indicates the URL of the site storing the first specification information, but the unit two-dimensional code 31 may directly indicate the specifications. In this case, communication between the terminal device 20 and the server 50 can be omitted during setting.

[0093] Furthermore, although the sensor two-dimensional code 41 attached to the current sensor 40 indicates the second specification information, it may instead indicate the URL of a website that stores the second specification information. In this case, the acquiring unit 22a can acquire the second specification information from the server 50 by communicating with the server 50 based on the first information obtained by capturing an image of the first two-dimensional code attached to the measuring unit 30 with the imaging unit 26.

[0094] [Variations of the method for obtaining specification information] The method of acquiring the first specification information from the measurement unit 30 is not limited to reading a two-dimensional code. For example, the acquisition unit 22a may capture an image of the measurement unit 30 itself using the imaging unit 26, analyze the image in which the measurement unit 30 appears, identify the specifications of the measurement unit 30, and acquire the first specification information indicating the identified specifications. A machine learning model may be used to analyze the image (identify the specifications).

[0095] Furthermore, the method of acquiring the second specification information from the current sensor 40 is not limited to reading a two-dimensional code. For example, the acquiring unit 22a may capture an image of the current sensor 40 itself using the imaging unit 26, analyze the image in which the current sensor 40 appears, identify the specifications of the current sensor 40, and acquire the second specification information indicating the identified specifications. A machine learning model may be used to analyze the image (identify the specifications).

[0096] In these cases, there is an advantage that it is possible to omit providing two-dimensional codes to the measurement unit 30 and the current sensor 40.
