Then, the terminal 9 transmits the read maintenance item information and component information to the server 7 (S403).

  Next, the server 7 searches the maintenance product information database 17 using the cylinder number of the received maintenance product information as a key, and acquires the type of the registered replacement part (S404). Next, the server 7 collates with the type acquired from the maintenance product information database 17 whether the type of the received component information is excessive or insufficient, and transmits the collation result to the terminal 9 (S405). That is, the server 7 collates whether or not the component information transmitted from the terminal 9 matches the replacement component information registered in advance in the maintenance product information database 17 without excess or deficiency.

Next, the terminal 9 displays the collation result on the screen (S406). Then, the terminal 9 confirms whether the collation result is excessive or insufficient (S407).
If there is no excess or deficiency, the process proceeds to S408.
If there is an excess or deficiency, the parts replacement is finished, and the worker 67 confirms the collected replacement parts.

  Next, the terminal 9 writes the component information read in S402 to the IC tag 13a attached to the maintenance product 3 (S408). Here, the component information to be written to the IC tag 13a may be any content desired by the customer company, and it is not necessary to write all the content of the component information. Then, the terminal 9 transmits the result of associating the maintenance product information and the component information to the server 7 (S409). Here, the pegging indicates which part 5 has been exchanged for which maintenance product 3, and on the memory 51 of the IC tag 13a, the cylinder number of the maintenance product 3, the part number of the part 5, and the like. It is a parent-child relationship.

Next, the server 7 holds the association result in the maintenance product information database 17 (S410). In addition, registration is performed so that the pre-registered type and the component information received from the terminal 9 correspond to each other.
Through the processing from S401 to S410, the consistency check of the collected replacement parts at the time of parts replacement, the linking of the maintenance product information on the memory 51 of the IC tag 13a and the part information, and the linking to the maintenance product information database 17 Functions such as result registration are realized.

  In this embodiment, the terminal 9 writes various types of information to the IC tag 13a and the IC tag 13b via the reader / writer 11. However, for example, necessary information is input via the input unit 43 of the reader / writer 11. Various information can be written in the IC tag 13a and the IC tag 13b without inputting data to the terminal 9 in such a manner. In this case, for example, the information acquired from the server 7 by the reader / writer 11 may be transmitted from the terminal 9 to the reader / writer 11 at a time and started to be held by the reader / writer 11 before starting a day's work. The information registered from the reader / writer 11 to the server 7 may be transmitted from the reader / writer 11 to the terminal 9 in a lump after one day of work is completed, and from the terminal 9 to the server 7. good. The reader / writer 11 may realize functions such as consistency check of collected replacement parts at the time of parts replacement and linking of maintenance product information and part information on the memory 51 of the IC tag 13a.

  In this embodiment, the linking result is held in the maintenance product information database 17, but for example, a database that holds only the linking result is prepared, the maintenance product information database 17, the parts information database 19, and the like. The same information may be held by setting the relation.

  As described above in detail, according to the embodiment of the present invention, the server 7 is held in the IC tags 13b of all the parts 5 to be replaced that are collectively read as a preliminary check for parts replacement. It is checked whether or not the part information matches the replacement part registered in advance in the maintenance product information database 17 without excess or deficiency. This can prevent human error in parts replacement.

  Next, as a link between the maintenance product 3 and the part 5 to be replaced, the terminal 9 writes part information of all the parts 5 to be replaced on the IC tag 13 a attached to the maintenance product 3. As a result, the maintenance product 3 and the part 5 to be replaced can be easily and accurately associated. Further, the customer company can confirm which part 5 has been newly replaced by reading the IC tag 13a of the maintenance product 3.

  Then, the association result is transmitted from the terminal 9 to the server 7, and the server 7 holds the maintenance product information database 17. As a result, the recording of replacement part management is automated, and work efficiency can be improved.
