  Periodic inspections are necessary to ensure safe plant operation. Equipment inspection history must be managed from the previous inspection at an equipment specific inspection cycle, and an inspection plan must be formulated. I must.

  However, in the above-described conventional technology, the replacement time or the like is simply stored in the tag in a fixed manner, and there is no consideration on the inspection history in which the inspection results are accumulated at regular intervals.

  In actual cases, equipment that requires periodic inspections is managed on a document basis, and for periodic inspections, the recommended inspection cycle is described in the instruction manual, etc., to call attention.

  An object of the present invention is to provide an inspection history management apparatus and an RFID tag capable of managing an inspection history.

  In order to achieve the above object, in the present invention, inspection history information read from an RFID tag in which inspection history information is written in a contactless manner is received together with identification information for identifying an inspection target device, and each of the identification information is supported. In addition, the inspection history information is stored.

  According to the present invention, it is possible to manage the inspection history.

  First, the best mode for carrying out the invention will be conceptually described by taking a nuclear power plant as an example. RF1D in which device attribute data including a device ID and an inspection time is stored for each of a plurality of devices used in the nuclear power plant. By attaching a tag and managing the inspection history and inspection timing of multiple devices using the device management terminal based on the device attribute data read from the RFID tag by the reader, the inspection device can be easily and quickly extracted without omission. At the same time, we have realized that equipment can be inspected reliably. Further, since the inspection record is automatically generated from the device data extracted from the device management terminal, the inspection work date, and the personal IDs of the worker and the work confirmer, the number of inspection record preparation steps can be reduced.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention. In the nuclear power plant, n switchboards 1 are installed. A device 2 that requires periodic inspection is mounted on the switchboard 1. The device 2 is attached with an RFID tag storing device attribute data including a device identification number (device ID) and an inspection time.

  The RFID tag 3 is a RAM type tag having a high frequency analog circuit of 2.45 GHz, and stores device attribute data such as an identification number (device ID), a model, a use start date, and an inspection date.

  The switchboard 1 is provided with a reader 4 that reads device attribute data transmitted from the RFID tag 3. The reader 4 reads the device attribute data stored in the RFID tag 3 and transmits it to the device management terminal 5. The device management terminal 5 has a database such as an identification number (device ID), a model, a recommended inspection cycle, a use start date and an inspection execution date, and stores attribute data for each device.

Such an inspection history management system conducts business between a manufacturer (business operator) and a user (customer) as follows. The manufacturer delivers the device 2 and the switchboard 1 with the RFID tag 3 storing the unique identification number (device ID) for each device requiring periodic inspection, and the device management terminal 5 using the identification number of the RFID tag 3, The user manages the inspection history with the device management terminal 5. In the configuration of FIG. 1, device attribute data transmitted by the RFID tag 3 attached to the device 2 is read by the reader 4 and transmitted to the device management terminal 5. The device management terminal 5 receives device attribute data from the reader 4 attached to the n switchboards 1 and inputs the device attribute data stored for each switchboard 1.

  Wireless communication is performed between the RFID tag 3 and the reader 4. The device management terminal 5 can perform device management by confirming the received device attribute data. The device management terminal 5 is managed in a table as shown in FIG. 2 based on the input device attribute data. The table includes items such as an identification number (device ID), a model, a tag number, a recommended inspection cycle, a use start date, and an inspection implementation date. In general, device tag numbers are numbered so as not to overlap, so that device management for each switchboard 1 can be performed. The device management terminal 5 generates a message for prompting an inspection plan when the inspection time of the device 2 requiring periodic inspection approaches. The user (customer) can plan the inspection of the equipment by this message, so that the missed inspection opportunity can be prevented.

  Each time a manufacturer (operator) or user (customer) inspects equipment, the writer 6 rewrites the inspection history data of the RFID tag 3, reads it with the reader 4, and gives it to the equipment management terminal 5. Accumulate historical data. The user (customer) can confirm on the screen of the device management terminal 5 that the device has been inspected. For example, if the device ID 1 of the switchboard 1- (1) is checked, the check execution date of the device ID1 of the switchboard 1- (1) is “** year / **** month”.

  Next, when the equipment is inspected, the personal IDs of the workers engaged in the inspection work and the confirmer can be registered (read), and an inspection record can be automatically generated.

  Although the embodiment of the present invention has been described so far, management when the device is exchanged and the data needs to be updated will be described with reference to FIG.

  The manufacturer (operator) attaches the RFID tag 3 storing device attribute data including the device ID and the inspection time to a new device. The device D read by the reader 4 is reflected in the device management terminal 5 using the tag number as a keyword, and is continuously managed.

  The device inspection history management is performed as described above. The RFID tag storing the device attribute data including the device ID and the inspection time is attached to each of a plurality of devices, and the device attribute data read from the RFID tag is attached. Based on this, the inspection time of a large number of devices is managed collectively by the device management terminal, so that inspection devices can be extracted in a short time without omissions, and future inspection plans can be performed reliably. Can do.

  In this way, an RFID tag storing device attribute data including device ID and inspection time is attached to each of a plurality of devices used in a nuclear power plant, and a plurality of devices are based on the device attribute data read from the RFID tag by a reader. The device management terminal manages the inspection history and inspection time of the equipment. Since management is performed by the device management terminal, inspection devices can be easily extracted in a short time without omission, and the devices can be reliably inspected.

  Moreover, the inspection record can be automatically generated from the device data extracted from the device management terminal, the inspection work date and time, and the personal IDs of the worker and the work confirmation confirmer.

  Attach an RFID tag storing device attribute data including device ID and inspection time for each device used in a nuclear power plant, and inspect multiple devices based on the device attribute data read from the RFID tag by a reader Since the history and the inspection time are managed by the device management terminal, the inspection device can be extracted easily and without omission in a short time, and the device can be surely inspected.

  In addition, since it is possible to automatically generate inspection records from the device data extracted from the device management terminal, the inspection work date, and the personal IDs of the workers and work confirmers, it is possible to reduce the inspection record creation man-hours. It is done.
