At this time, when there are a plurality of inspection items, the plurality of inspection items are displayed on the display screen. When one inspection item is selected after displaying the inspection item on the display screen, the operation control unit 161 extracts the content of the inspection item from the inspection item storage unit 171 and displays it on the display screen (step S12). . Thereby, the user can confirm the inspection values such as the parts and instruments of the equipment and equipment for which the maintenance inspection work is performed, the position where the barcode to be imaged by the camera is pasted, the inspection content to be input and the meter reading result. .

After the contents of the inspection item are displayed, when the barcode is captured and image data is generated, the barcode reader 13 acquires facility information registered in the barcode from the image data (step S13).
When the barcode is read by the barcode reader 13, the GPS processing unit 14 receives a signal from a GPS satellite, and acquires position information of the mobile terminal device 1 from the received signal (step S14).
The acquired facility information and position information are output to the control unit 16.

  When the facility information and the position information are acquired, the operation control unit 161 displays, for example, a message on the display screen requesting input of an inspection value. After this display is performed, when the operation input of the inspection value is detected, the input unit 11 outputs the inspection value to the control unit 16 (step S15).

  When the inspection value is input, the registration unit 162 of the control unit 16 acquires time information related to the time when the inspection value is input by the time measuring unit 15, and this time information and the facility information acquired from the barcode reader 13 The position information acquired from the GPS processing unit 14, the user information registered in the memory in advance, and the inspection value acquired from the input unit 11 are stored in the storage unit 17 in association with each other (step S16). Thereby, the inspection value is stored in the storage unit 17 in a state associated with the time information, the facility information, the position information, and the user information.

  When the inspection value or the like is stored in the storage unit 17, the output unit 18 outputs the information stored in the storage unit 17 (step S17). For example, when the user accesses a management server or the like that centrally manages equipment for which maintenance and inspection work has been performed via a network or directly connects the mobile terminal device 1 to the management server, the output unit 18 stores The inspection value etc. memorize | stored in the part 17 are output to a management server. Thereby, the management server can monitor the state of the equipment.

  As described above, according to the present embodiment, the inspection value acquired from the equipment and the equipment information read from the barcode attached to the equipment and the GPS signal when the equipment information is acquired. Since the position information acquired from the above is correlated, the equipment that has acquired the inspection value and the position when the inspection value is acquired can be backed up, and as a result, a highly reliable inspection value can be acquired. it can.

  In addition, according to the present embodiment, since the time information is further associated with the inspection value, it is possible to specify the time when the inspection value was acquired, and thus the obtained inspection value is highly reliable. It will be a thing.
