FIG. 8B shows a flowchart for explaining operation mode switching processing using the reader / writer 251. First, in S721, the mode switching processing unit 226 determines whether or not the identifier stored in the IC tag is read by the reader / writer 251. If the identifier stored in the IC tag is read (S721: YES), the process proceeds to S722. In S722, the mode switching processing unit 226 compares the read identifier with the identifiers of all the transmission towers 2 scheduled for patrol on that day. Here, the identifiers of all the transmission towers 2 scheduled for inspection on the day are downloaded from the server computer 300 by the inspection recording system 224 and stored in the memory 212.

  In S723, the mode switching processing unit 226 determines whether there is a power transmission tower 2 with the same identifier. Here, when there is no power transmission tower 2 with the same identifier, the mode switching processing unit 226 instructs the inspection recording system 224 to operate in the inspection route mode. Thereby, the operation mode of the inspection recording system 224 is switched to the inspection path mode (S724). On the other hand, if there is a transmission tower 2 with an identifier that matches, the mode switching processing unit 226 instructs the patrol recording system 224 to operate in the tower mode. Thereby, the operation mode of the patrol recording system 224 is switched to the tower mode (S725).

  According to the second embodiment described above, the operation mode of the PDA 200 depends on whether or not the identifier read by the reader / writer 251 matches the identifier assigned to the power transmission tower scheduled for inspection on the day.

First, in S731, the mode switching processing unit 226 determines whether or not the wireless communication control unit 221 is in a state where it can communicate with the wireless device 100. If the communication is possible (S731: YES), the process proceeds to S732. In S732, the mode switching processing unit 226 compares the SSID (Service Set IDentifier), which is the terminal ID received from the wireless device 100, with the SSIDs of the wireless devices 100 provided in all the transmission towers scheduled for inspection on the day. . Here, the SSIDs of the wireless devices 100 provided in all the power transmission towers 2 scheduled for patrol on that day are downloaded from the server computer 300 by the patrol recording system 224 and stored in the memory 212.

  In S733, the mode switching processing unit 226 determines whether or not there is a wireless device 100 having the same SSID. If there is no wireless device 100 with the same SSID, the process returns to S731. On the other hand, if there is a wireless device 100 that matches the SSID, the process proceeds to S734.

  In S734, the mode switching processing unit 226 determines whether the electric field strength of the received signal received from the wireless device 100 is greater than or equal to a predetermined value. Here, when the electric field strength of the received signal is less than a predetermined value (for example, −20 dBm) (S734: NO), the mode switching processing unit 226 instructs the inspection recording system 224 to operate in the inspection route mode. To do. Thereby, the operation mode of the inspection recording system 224 is switched to the inspection path mode (S735). On the other hand, when the intensity of the received signal is equal to or higher than the predetermined value (S734: YES), the mode switching processing unit 226 instructs the patrol recording system 224 to operate in the tower mode. As a result, the operation mode of the patrol recording system 224 is switched to the tower mode (S736).

  According to the third embodiment described above, the operation mode of the PDA 200 is automatically set according to whether or not the SSID acquired from the wireless device 100 matches the stored identifier assigned to the transmission tower scheduled for patrol on that day. Switch. For this reason, the patrol person 3 can input information to the PDA 200 and refer to information using the PDA 200 without performing complicated operations such as fine button operations and input operations, and efficiently and smoothly perform the patrol. be able to. Note that the position at which the operation mode is switched can be adjusted by changing a predetermined value compared with the electric field strength of the received signal in S734.

  In the first embodiment described above, when the current position cannot be calculated, such as when radio waves sent from GPS satellites cannot be received, the operation mode shown in FIG. A screen for prompting selection is displayed, and the operation mode selected by the operation input performed by the patrolman 3 on the input device is manually switched. Similarly, in the case of the second embodiment or the third embodiment, when the identifier cannot be read from the IC tag 6 or when the terminal ID cannot be acquired, the display device 218 of the PDA 200 displays, for example, FIG. 9 displays a screen for prompting selection of an operation mode (referred to as an operation mode selection screen 900), and manually switches to an operation mode selected by an operation input performed by the patrolman 3 on the input device.
