In the maintenance system having such a configuration, the tag reading unit 302 of the maintenance terminal 30 reads the serial number and the inspection record information of the device in which the one wireless tag 10 is installed from the one wireless tag 10, and the server The reading unit 307 reads the inspection record information associated with the serial number read by the tag reading unit from the server device 20.
Thereby, at the time when the field maintenance staff specifies the repair target device in the plant facility, the inspection record information can be read from the wireless tag 10 installed in the repair target device. Further, when the trouble cannot be dealt with only by the inspection record, the maintenance terminal 30 can receive more detailed inspection record information from the server device 20 by moving to a place where the communication status of the wireless network is good. .

Next, the operation of the maintenance system according to the present embodiment will be described. First, the operation at the time of reading the inspection record information will be described.
FIG. 5 is a flowchart showing the operation of the maintenance terminal when the inspection record information is read.
When the field maintenance staff activates the maintenance terminal 30 and executes the reading process of the inspection record information, the tag communication unit 301 starts outputting a signal for reading the inspection record information, the initial information, and the tag replacement date / time from the wireless tag 10 ( Step S101). When the field maintenance staff brings the maintenance terminal 30 close to the wireless tag 10, the wireless tag 10 is activated by electromagnetic induction and transmits a signal indicating inspection record information, initial information, and tag replacement date and time stored in the storage circuit. When the wireless tag 10 transmits a signal, the tag reading unit 302 reads inspection record information, initial information, and tag replacement date and time from the signal (step S102).

  Next, the conversion unit 304 converts the fixed phrase code included in the inspection record information read by the tag reading unit 302 into a fixed sentence (step S103). For example, when the tag reading unit 302 reads “1 =“ 2010/03/01 00:00:00 ”, 2 = 20, 3 = 31, 4 = 40, 5 = 51” as inspection record information, conversion is performed. The unit 304 refers to the information in the fixed sentence storage unit (FIG. 4) and sets the inspection record information as “inspection date = 2010/03/01 00:00:00, signal input / output confirmation result = no abnormality, communication Confirmation result = Communication not possible, Visual inspection result = No abnormality, Detailed record presence = Yes ".

Next, the display unit 305 displays the initial information and tag replacement date and time read by the tag reading unit 302 and the inspection record information converted by the conversion unit 304 on the screen (step S104). Thereby, the field maintenance staff refers to the inspection record information and inspects whether there is an abnormality in the device.
Next, the input unit 308 receives an input as to whether or not to read more detailed inspection record information and an instruction manual from the server device 20 (step S105). When the field maintenance staff determines that the equipment is defective and more detailed information is required, or when checking whether or not the equipment is defective, the on-site maintenance staff reads the information from the server device 20. input. On the other hand, the field maintenance staff inputs that the information from the server device 20 is not read when there is no problem with the device or when there is a problem with the device but the information can be dealt with only by the information read from the wireless tag 10. .

When the input unit 308 receives an input for reading information from the server device 20 (step S105: YES), the tag reading unit 302 stores the serial number included in the initial information read from the wireless tag 10 in the storage unit 310. Recording is performed (step S106).
When the input unit 308 receives an input indicating that the information is not read from the server device 20 in step S105 (step S105: NO), or the tag reading unit 302 records the serial number in the storage unit 310 in step S106. In such a case, the input unit 308 receives an input as to whether or not to read the device information from the other wireless tag 10 (step S107). When the input unit 308 receives an input for reading device information from another wireless tag 10 (step S107: YES), the process returns to step S1 to read information from the other wireless tag 10.

  On the other hand, when the input unit 308 receives an input indicating that the device information is not read from the other wireless tag 10 (step S107: NO), the display unit 305 prompts the screen to move to a place with good communication status. A message is displayed (step S108). Next, the communication status determination unit 311 determines whether or not the communication status with the wireless network is good (step S109). When the communication status determination unit 311 determines that the communication status with the wireless network is not good (step S109: NO), the determination in step S109 is repeated and waits until the communication status becomes good.

When the communication status determination unit 311 determines that the communication status with the wireless network is good (step S109: YES), the server reading unit 307 stores the serial number stored in the storage unit 310 via the server communication unit 306. A request for transmission of inspection record information and an instruction manual associated with is transmitted (step S110).
When the server device 20 receives the inspection record information and the instruction manual transmission request from the maintenance terminal 30, the server device 20 reads the inspection record information and instruction manual associated with the serial number included in the transmission request from the database, and sends them to the maintenance terminal 30. Send.
Next, the server reading unit 307 of the maintenance terminal 30 reads the inspection record information and the instruction manual from the server device 20 via the server communication unit 306 (step S111). Then, the display unit 305 displays the read inspection record information and instruction manual on the screen (step S112), and ends the process.

Thereby, at the time when the field maintenance staff specifies the repair target device in the plant facility, the inspection record information can be read out from the wireless tag installed in the repair target device. If the trouble cannot be dealt with only by the inspection record, the maintenance terminal 30 can receive more detailed inspection record information from the server device 20 by moving outside the plant equipment that can communicate with the wireless network. it can.
Therefore, the field maintenance staff can deal with the trouble of the control device immediately.

Next, the operation at the time of writing inspection record information will be described.
FIG. 6 is a flowchart showing the operation of the maintenance terminal when the inspection record information is written.
When the field maintenance staff activates the maintenance terminal 30 and inputs inspection record information to the maintenance terminal 30, the input unit 308 receives input of inspection record information (step S201). Next, the input unit 308 records arbitrary input information in the storage unit 310 among the maintenance record information that has been accepted (step S202).

  Next, the tag communication unit 301 starts outputting a signal for reading the serial number of the device from the wireless tag 10 (step S203). When the field maintenance staff brings the maintenance terminal 30 close to the wireless tag 10, the wireless tag 10 is activated by electromagnetic induction and transmits a signal indicating the serial number stored in the storage circuit. When the wireless tag 10 transmits a signal, the tag reading unit 302 reads a serial number from the signal (step S204). Next, the tag reading unit 302 records the read serial number in the storage unit 310 (step S205).

  Next, the tag writing unit 309 outputs, to the wireless tag 10 via the tag communication unit 301, a signal indicating the standard input information and the selected input information among the inspection record information received by the input unit 308 (step S206). ). When the wireless tag 10 receives a signal from the maintenance terminal 30, the wireless tag 10 newly adds inspection record information (standard input information and selection input information) to the inspection record information area of the storage circuit. As described above, the maintenance terminal 30 writes the fixed input information and the selected input information, which have a relatively small data amount as compared with the arbitrary input information, to the wireless tag 10. Thereby, the maintenance terminal 30 can prevent the storage capacity of the wireless tag 10 from being wasted.

  Next, the display unit 305 displays a message that prompts the user to move to a place with good communication status on the screen (step S207). Next, the communication status determination unit 311 determines whether or not the communication status with the wireless network is good (step S208). When the communication status determination unit 311 determines that the communication status with the wireless network is not good (step S208: NO), the determination in step S208 is repeated and waits until the communication status becomes good.

When the communication status determination unit 311 determines that the communication status with the wireless network is good (step S208: YES), the server writing unit 312 stores the serial number stored in the storage unit 310 via the server communication unit 306. And inspection record information is transmitted (step S209).
When the server device 20 receives the serial number and the inspection record information from the maintenance terminal 30, the server device 20 registers the inspection record information in the database in association with the received serial number.
When the server writing unit 312 of the maintenance terminal 30 transmits the serial number and the inspection record information to the server device 20, the processing ends.
Thereby, the maintenance terminal 30 can write the inspection record information in association with the serial number of the device in the wireless tag 10 and the server device 20.
