Here, an example of an operation in the case where the worker performs maintenance work for exchanging the part 37 of the maintenance target device 35 with the replacement part 34 will be described.

  Hereinafter, first, an operation example of each device will be described, and then a sequence example will be specifically described.

  First, an operation example of the server 11 alone will be described with reference to FIG.

  The worker at the maintenance work place 3 uses the communication terminal 31 to read the tag information in the RFID tag 21 installed in the instruction sheet 33 and sends it to the server 11 together with the procedure information transmission start request when starting the work. To do. An example of this operation will be described later. When the server 11 receives the procedure information transmission start request including the tag information, the server 11 starts the following processing.

  In FIG. 5, when a procedure information transmission start request including tag information is received (S501), the procedure information transmission unit 151 initializes a variable “n” used in the following processing. Specifically, the procedure information transmission unit 151 sets “n = 1” (S502).

  The procedure information transmitting unit 151 extracts the tag information included in the procedure information transmission start request, and reads the maintenance work table 161 having the maintenance work identification ID 301 that matches the extracted tag information from the secondary storage device 113 ( S503). Next, the procedure information transmission unit 151 reads the “n” -th procedure from the maintenance work table 161 read in S503 (S504), and transmits the procedure information transmission start request to the communication terminal 31 that has transmitted the request (S505). Specifically, for example, the procedure information transmission unit 151 reads out the transmission tag ID 303, the work content 304, the details 305, and the like associated with the procedure 302 “n” from the maintenance work table 161 read out in S503. It transmits to the communication terminal 31 that transmitted the transmission start request.

  The worker performs the received procedure. This process will be described later. When the worker finishes the work of the received procedure, the worker transmits a procedure work end for notifying the work end of the procedure using the communication terminal 31. An example of this operation will be described later.

  When the procedure information transmission unit 151 of the server 11 receives the completion of the procedure work (S506), the procedure information transmission unit 151 determines whether all the tasks have been completed (S507). For this purpose, for example, the procedure information transmission unit 151 determines whether or not the value of “n” matches the maximum value of the procedure 302 in the maintenance work table 161 read in S503. As a result of this determination, when the value of “n” matches the maximum value of the procedure 302, the procedure information transmission unit 151 determines that all the work has been completed.

  If all the operations are completed as a result of the determination in S507, the procedure information transmission unit 151 transmits maintenance operation completion notification information for notifying the completion of the maintenance operation to the communication terminal 31 (S508), and the processing is terminated.

  As a result of the determination in S507, if not all work has been completed, the procedure information transmission unit 151 calculates “n = n + 1” (S509), and performs the above-described processing of S504 again.

  Next, an operation example of the communication terminal 31 alone will be described with reference to FIG.

  As described above, the worker at the maintenance work place 3 first instructs the start of the maintenance work using the input device 44 of the communication terminal 31 at the start of the work, and holds the reader / writer 32 over the instruction sheet 33.

  When the maintenance work start instruction is input (S601), the work instruction control unit 412 of the communication terminal 31 instructs the reader / writer control unit 411 to read. The reader / writer control unit 411 reads the tag information from the RFID tag 21 by controlling the reader / writer 32 (S602). The work instruction control unit 412 transmits a procedure information transmission start request including the tag information read by the reader / writer control unit 411 to the server 11 (S603).

  The server 11 transmits procedure information including tag information, information for notifying the end of work, or the like to the communication terminal 31 by the above-described processing.

  When receiving the information transmitted from the server 11 (S604), the work instruction control unit 412 of the communication terminal 31 determines whether the received information is maintenance work end notification information for notifying the end of work (S605).

  If the received information is a maintenance work end notification as a result of the determination in S605, the work instruction control unit 412 outputs information for notifying the end of the maintenance work to the output device 45 (S606), and the process ends.

  If the received information is not a maintenance work end notification as a result of the determination in S605, the work instruction control unit 412 outputs the received procedure information to the output device 45 (S607). Specifically, for example, the work instruction control unit 412 outputs the work content 304, details 305, and the like included in the procedure information to the output device 45. An example of a screen displaying the procedure information on a display or the like is shown in FIG. In FIG. 7, a screen 701 is an example in which information such as work contents 304 and details 305 is displayed using image data included in the details 305 of the procedure information.

  In FIG. 6, the work instruction control unit 412 extracts tag information from the received procedure information, and instructs the reader / writer control unit 411 to output the extracted tag information. The reader / writer control unit 411 controls the reader / writer 32 and outputs tag information (S608). An example of the operation of the reader / writer control unit 411 is the same as that of the prior art.

  On the other hand, the worker at the maintenance work place 3 refers to the information output to the output device 45 and holds the reader / writer 32 over the replacement part 34, the replacement target part 36, the part 37, or the like. At this time, tag information is output from the reader / writer 32 by the processing of S608 described above. As described above, when the same information as the tag information held by the RFID tag 22, the RFID tag 23, and the RFID tag 24 installed in the replacement part 34, the replacement target part 36, the part 37, and the like is input. Sound buzzer, turn on LED light, etc. Thus, the worker recognizes what is used in the procedure transmitted from the server 11 and performs the procedure instructed by the procedure information. After performing the work of this procedure, the operator uses the input device 44 to input procedure work end information indicating the end of the procedure.

  When the end of the procedure work is input (S609), the work instruction control unit 412 of the communication terminal 31 transmits the procedure work end to the server 11 (S610). Next, the work instruction control unit 412 performs the processes after S604 described above again.
