Further, the image storage unit 16 is realized by the HDD 24 mounted on the mobile terminal 10. Alternatively, the RAM 23 or an external storage means may be used via a network.

  The management device 4 includes a meter management information management unit 41 that performs information management such as generation, update, and deletion of meter management information for managing a meter installed in a facility, and a meter management information storage unit that stores meter management information 42.

  The meter management information stored in the meter management information storage unit 42 includes, for each electric meter 1, the manufacturing number, model, meter value, number of display digits of the meter value, decimal point position of the meter value, and multiplication factor. , The number of pulses generated via the controller 3, the pulse constant, the unit of the pulse constant, the amount of power used, and the like are included for managing the electric meter 1 and the amount of power used by the electric meter 1. ing. The meter management information includes information that is updated as appropriate, such as a meter value and power consumption, in addition to a fixed value such as a model. The meter value is obtained from the amount of power used, the number of generated pulses, the pulse constant, the multiplication factor, and the like.

  The meter management information management unit 41 is realized by a cooperative operation of a computer that forms the management device 4 and a program that operates on the CPU 21 mounted on the computer. The meter management information storage unit 42 is realized by an HDD mounted on the management device 4.

  Further, the program used in this embodiment can be provided not only by communication means but also by storing it in a computer-readable recording medium such as a CD-ROM or USB memory. A program provided from a communication unit or a recording medium is installed in a computer, and various processes are realized by the CPU 21 of the computer sequentially executing the program.

  When the electric meter 1 is periodically replaced or newly added, the worker brings together a plurality of electric meters 1 and brings them into a facility such as a tenant building, for example, and sequentially proceeds with the installation work of the electric meter 1 in the tenant building. Go. When bringing in a plurality of types of electric meters 1, the worker attaches the designated types of electric meters 1 corresponding to a predetermined tenant according to the work plan. At this time, the worker may make a work mistake such as a selection mistake or a connection mistake of the electric meter 1. The present embodiment is characterized in that such work mistakes are easily detected.

  In addition, the installation work referred to in the present embodiment includes not only a physical installation work in which an operator installs the electric meter 1 at a predetermined position and wiring, but also a confirmation work after the installation. This embodiment provides a process for supporting a confirmation work after a physical attachment work by an operator.

  Next, attachment support processing of the electric meter 1 in the present embodiment will be described using the flowchart shown in FIG.

  After the electric meter 1 is newly attached, the worker checks whether the electric meter 1 is properly attached, that is, whether the electric meter 1 of the correct model is attached with the correct wiring. For this purpose, the worker manually operates the test switch (not shown) of the electric meter 1 to generate a predetermined number of pulses (step 101). The electric meter 1 generates a pulse when electric power is used. The amount of electric power used is measured by the number of generated pulses. The meter value is incremented every time a certain number of pulses are generated. The constant for incrementing the meter value varies depending on the electric meter model. The worker generates a predetermined number of pulses, and then photographs the electric meter 1 with the camera 6. When the electric meter 1 is photographed by the worker, the image acquisition unit 11 acquires the imaging data (step 102).

  FIG. 4 is a diagram illustrating an example of an image of the panel portion of the electric meter 1 photographed by an operator. On the display panel 50 of the electric meter 1, information necessary for calculating the usage fee, such as the amount of power used, is displayed by the meter in terms of the amount of power used by marking or printing. The displayed information is basically the same regardless of the manufacturer and model of the electric meter, but the display form and display format of each information may differ depending on the manufacturer and model of the electric meter. is there. In FIG. 4, a meter value display unit 51, a multiplication factor 52, and a pulse constant 53 indicating the power consumption can be read. Further, the meter value display section 51 and the pulse constant 53 display accompanying information 54 and 55 “kWh” and “pulse / kWh” indicating the unit of each numerical value in the vicinity.

  In this embodiment, the pulse is generated by a human operation. However, after the electric meter 1 is attached, the electric meter 1 is used for measurement for a predetermined time (for example, 10 minutes). It is also possible to generate pulses.

  When the imaging data is acquired in step 102, the meter management information acquisition unit 12 acquires meter management information at the time of acquisition from the management device 4 (step 103). In parallel with this, the image processing unit 13 performs image processing on the imaging data to extract a meter value from the imaging data (step 104). In the vicinity of the meter value display section 51, the accompanying information 54 “kWh” indicating the unit of the numerical value is displayed regardless of the manufacturer and model of the electric meter 1, and therefore a string of numbers in the vicinity of the accompanying information 54 is displayed. May be extracted as a meter value. Alternatively, the meter value is displayed as a white number in the display unit 51 of the black region, and therefore a digit string in the black region having a predetermined size may be extracted as the meter value. . Of course, the meter value may be extracted by using a method other than that exemplified above.

  Subsequently, the comparison determination unit 14 compares the meter value extracted from the imaging data with each meter value included in the meter management information acquired by the meter management information acquisition unit 12, and matches the extracted meter value. An electric meter corresponding to the meter management information is specified (step 105). And the result display part 15 displays the manufacture number of the specified electricity meter on the display 27 (step 106). In the present embodiment, the result is displayed on the display 27, but the output destination of the result is not limited to the display 27. For example, a smartphone carried by an operator may be used.

  The worker collates the displayed serial number with the serial number of the newly installed electric meter 1. Thereby, if the serial numbers match, it can be determined that the legitimate electric meter 1 is attached. If the serial numbers do not match, it means that a different electric meter is attached, thereby detecting a work mistake.

  Even if the amount of power used is the same, the meter values indicated by the electric meter 1 and the meter management information differ if the pulse constants are different. That is, since the meter value may be different depending on the model of the electric meter, if the meter value is different, it can be easily determined that the invalid electric meter 1 is attached.

  Incidentally, it may be assumed that a plurality of electric meters are specified in step 105. In this case, if the attached electric meter 1 is included in the plurality of electric meters, it may be determined that the legitimate electric meter 1 is attached. If multiple electricity meters are extracted, the operator will be careful to compare the serial numbers, so installation errors can be easily detected.

  In the present embodiment, since the newly installed electric meter 1 is assumed to be new, the meter value immediately after installation should normally indicate zero. However, it may not be 0 for some reason. In consideration of this case, Steps 102 to 103 may be performed before the pulse generation in Step 101, and in Step 104, the difference between the meter values before and after the pulse generation may be obtained as the meter value.

  As described above, in the present embodiment, the validity of the installation work of the electric meter 1 is confirmed based on the meter value. However, the validity of the installation work of the electric meter 1 may be confirmed based on information other than the meter value.

  For example, the position of the decimal point and the number of display digits in the display unit 51 may vary depending on the model. Therefore, the characteristic information indicating the characteristic of the electric meter obtained from the display panel 50 of the electric meter may be extracted from the imaging data and collated with the meter management information.

  The characteristic information used for determining whether the attached electric meter 1 is correct, such as the meter value and the number of display digits in the display unit 51, may be used in appropriate combination. By combining them, it is possible to improve the accuracy of determining the validity.

  Further, in the present embodiment, the imaging data obtained by photographing with the camera 6 is stored in the image storage unit 16, but the stored imaging data is recorded in the attachment work, the work is improved, the service quality is improved, and the like. You may use it.

  In the present embodiment, the meter management information of all electric meters is acquired in step 103 and the validity of the electric meter 1 attached by the portable terminal 10 is confirmed. The meter value may be passed to the device 4 for confirmation of the validity, and the result may be acquired from the management device 4 and notified to the worker.

  In the present embodiment, an electric meter is described as an example of a metering meter. However, the meter can be applied to other metering meters such as a gas meter and a water meter.
