Abstract

In a machine element control method, when conducting maintenance and inspection of a machine element assembly such as a plant to be operated for a long period of time exceeding life of RFID tags, to enable use of the RFID tags to identify respective machine elements, new RFID tags are additionally attached and a correspondence with respect to the RFID tags are stored and verified.

Claims

1. A machine element control apparatus for assisting maintenance and inspection of machine elements constituting a machine element assembly, on the basis of designing information of the machine element assembly;

comprising;

maintenance and inspection information input means capable of receiving an input of data and outputting data for inputting maintenance and inspection information;

control database means having stored therein the maintenance and inspection information and the designing information; and

Radio Frequency Identification (RFID) tag ID reader means capable of accessing an RFID tag having stored information for reading the information therefrom, wherein

the control database means stores therein a maintenance and inspection schedule created on the basis of the designing information;

the RFID tag ID reader means reads an RFID tag ID as the information; and

the maintenance and inspection information input means displays the maintenance and inspection schedule and inspection items stored in the control database means, receives an input of information of maintenance and inspection findings associated with the maintenance and inspection schedule and inspection items thus displayed, and stores information of an indication for inspection, the maintenance and inspection finding information, and the RFID tag ID in the control database means with a correspondence established therebetween.

2. A machine element control apparatus according to claim 1, wherein

the RFID tag ID reader means reads an RFID tag ID;

and

the maintenance and inspection information input means searches the control database means for information of an inspection indication stored therein in association with the RFID tag ID and displays the information.

3. A machine element control apparatus according to claim 2, wherein:

the RFID tag ID reader means reads, if the RFID tag ID cannot be read, another RFID tag ID; and

the maintenance and inspection information input means stores the second RFID tag ID and information of maintenance and inspection findings in the control database means with a correspondence established therebetween.

4. A machine element control apparatus according to claim 2, wherein

the maintenance and inspection information input means searches, if the RFID tag ID can be read by the RFID tag ID reader means, the control database means for information of an inspection indication stored therein with a correspondence established with respect to the RFID tag ID and displays the information;

the RFID tag ID reader means reads another RFID tag ID; and

the maintenance and inspection information input means stores the RFID tag ID, said another RFID tag ID, and the information of maintenance and inspection findings in the control database means with a correspondence established therebetween.

5. A machine element control apparatus according to claim 4, wherein

when the maintenance and inspection information input means searches, if the RFID tag ID can be read by the RFID tag ID reader means, the control database means for information of an inspection indication stored therein with a correspondence established with respect to the RFID tag ID and displays the information;

the maintenance and inspection information input means detects an error in the correspondence and deletes information of maintenance and inspection findings associated with the correspondence.

6. A machine element control method for use with a machine element control apparatus for assisting maintenance and inspection of machine elements constituting a machine element assembly, on the basis of designing information of the machine element assembly,

the machine element control apparatus comprising maintenance and inspection information input means capable of receiving an input of data and outputting data for inputting maintenance and inspection information, control database means having stored therein the maintenance and inspection information and the designing information, and RFID tag ID reader means capable of accessing an RFID tag having stored information for reading the information therefrom, the method comprising the steps of:

storing, by the control database means, a maintenance and inspection schedule created on the basis of the designing information;

reading, by the RFID tag ID reader means, an RFID tag ID as the information; and

displaying, by the maintenance and inspection information input means, the maintenance and inspection schedule and inspection items stored in the control database means, receiving an input of information of maintenance and inspection findings associated with the maintenance and inspection schedule and inspection items thus displayed, and storing information of an indication for inspection, the maintenance and inspection finding information, and the RFID tag ID in the control database means with a correspondence established therebetween.

7. A machine element control method according to claim 6, further comprising the steps of;

reading, by the RFID tag ID reader means, an RFID tag ID; and

searching, by the maintenance and inspection information input means, the control database means for information of an inspection indication stored therein in association with the RFID tag ID and displaying the information.

8. A machine element control method according to claim 7, further comprising the steps of:

reading by the RFID tag ID reader means, if the RFID tag ID cannot be read, another RFID tag ID; and

storing, by the maintenance and inspection information input means, said another RFID tag ID and information of maintenance and inspection findings in the control database means with a correspondence established therebetween.

9. A machine element control method according to claim 8, further comprising the steps of:

searching by the maintenance and inspection information input means, if the RFID tag ID can be read by the RFID tag ID reader means, the control database means for information of an inspection indication stored therein with a correspondence established with respect to the RFID tag ID and displaying the information;

reading another RFID tag ID by the RFID tag ID reader means; and

storing by the maintenance and inspection information input means, the RFID tag ID, said another RFID tag ID, and the information of maintenance and inspection findings in the control database means with a correspondence established therebetween.

10. A machine element control method according to claim 7, further comprising the steps of:

detecting;

when the maintenance and inspection information input means searches, if the RFID tag ID can be read by the RFID tag ID reader means, the control database means for information of an inspection indication stored therein with a correspondence established with respect to the RFID tag ID and displays the information;

by the maintenance and inspection information input means an error in the correspondence and deleting information of maintenance and inspection findings associated with the correspondence.
