Description

  The present invention relates to a portable storage medium for managing traceability of an instrument, an RFID (Radio Frequency Identification) tag attached to the instrument, an instrument with the RFID tag, and an instrument for managing traceability of the instrument with the RFID tag The present invention relates to a traceability management device, a management method, a management program, and a management program storage medium.

  In recent years, RFID tags have attracted attention as an alternative to barcodes. The RFID tag has a configuration in which an antenna for performing wireless communication is attached to an IC (Integrated Circuits) chip on which a nonvolatile memory and a wireless communication circuit are mounted. The nonvolatile memory can be written as well as read out by using a tag reader / writer equipped with wireless communication means. That is, in the RFID tag, unlike the printed barcode, the recorded contents can be easily changed. Furthermore, the amount of information that can be stored in the RFID tag is significantly larger than that of a barcode. As a result, RFID tag applications are expanding far beyond the application range of barcodes.

  By the way, in the field of industrial product design / development and manufacturing / shipment inspection, it is required to strictly implement calibration management of instruments based on the requirements of ISO (International Organization for Standardization) 9000 standards related to quality control. It has become. Moreover, in the calibration management, it is required to manage not only the records of calibration of instruments, but also the calibration certificates and traceability system diagrams used to calibrate the instruments. .

  Here, the traceability system diagram is the instrument used to calibrate a certain instrument, the instrument used to calibrate the instrument used for the calibration, and the instrument used for the calibration going back further. It is the figure which showed the genealogy used until it reached the standard instrument which a country used to calibrate.

  In general, it is easy for a calibration operator to know what instrument was used to calibrate an instrument. However, it is not immediately clear what instrument the instrument used to calibrate the instrument was previously calibrated. This is because, in many cases, calibration of a meter that has calibrated the meter is often performed by other companies such as a meter manufacturer. Therefore, when trying to create a traceability system diagram, it is necessary to go back one by one to check the instruments used for calibration, and in some cases, obtain calibration records and calibration certificates from several instrument manufacturers. . This is a laborious operation.

  In general, an apparatus such as a spectrum analyzer in which instruments are combined is not called an instrument but is often called a measuring instrument. Also, for example, devices such as power supply devices and pulse generators are not called meters. However, since devices such as power supply devices and pulse generators are signals that serve as references for other signals, they are often calibrated in the ISO9000 standard and the like. Therefore, in this specification, the measuring instrument and all the devices to be calibrated are collectively referred to as an instrument.

Patent Document 1 discloses an example of a device management system that facilitates device management such as calibration management by attaching a barcode or RFID tag to various devices including a meter. Patent Document 2 discloses an example of a system for obtaining a calibration certificate of a meter used for calibration from the manufacturer of the meter via the Internet.
JP 2003-99662 A (paragraph 0026 to paragraph 0028, FIGS. 1 to 4) JP 2003-178390 A (paragraphs 0010 to 0024, FIGS. 1 and 4)

  However, according to the device management system disclosed in Patent Document 1, once the RFID tag attached to the device including the instrument, such as the device name, identification number, and data related to the specification, is written, Only writes data that does not need to be changed. Therefore, in this device management system, for example, the result of meter calibration performed periodically such as once a year is not written and managed in the RFID tag. Also, a device management server that manages devices attached with RFID tags does not provide means for easily displaying a calibration certificate of a meter or a traceability system diagram, or for facilitating the acquisition thereof.

  Further, according to Patent Document 2, if a meter used for calibration of a meter is known, acquisition of a calibration certificate is facilitated. However, since no means for displaying the traceability system diagram is provided, no information is provided on which instrument the instrument used for calibration was calibrated. Therefore, it takes time and effort to trace and trace the instrument used for calibration of the instrument used for calibration as in the past.

  SUMMARY OF THE INVENTION In view of the above problems of the prior art, an object of the present invention is to provide means capable of easily displaying a traceability system diagram of an instrument, and to use the instrument used to calibrate the instrument, and the instrument It is an object of the present invention to provide means and a method for facilitating the acquisition of a calibration certificate for a further upstream instrument used to calibrate the instrument used to calibrate the instrument.

  In order to solve the above problems, the portable storage medium or RFID tag of the present invention is attached to a meter, and the meter, the meter used to calibrate the meter, and the calibration of the meter used for the calibration For each of the instruments up to the specified standard instrument, the instrument identification number data, calibration date, calibration expiration date, calibration certificate number, and instrument Is stored in the nonvolatile memory in a memory including at least one data of the identification number of the meter to be calibrated. Moreover, the meter of the present invention is characterized in that the RFID tag is attached.

  In these RFID tags or instruments, data relating to calibration of not only the instrument but also the instrument used to calibrate the instrument and the instrument used to calibrate the instrument used for the calibration are stored. Therefore, the traceability system diagram can be easily created by reading the data stored in the RFID tag. Since the RFID tag stores data such as a calibration certificate number, the calibration certificate can be easily obtained.

  Further, the instrument traceability management device of the present invention comprises an RFID tag reader / writer for reading or writing data of an RFID tag attached to the instrument, and a memory for storing the data, the instrument, Instrument identification number data for each of the instruments used for calibration of the instrument and the instruments used for calibration of the instrument used for the calibration up to a predetermined standard instrument Data including at least one of the calibration date, calibration expiration date, calibration certificate number, and identification number of the meter targeted for calibration by the meter is written and managed in the RFID tag It is an instrument traceability management device. Then, the instrument traceability management apparatus, when the instrument is calibrated, receives at least the identification number data of the instrument, the calibration execution date, the calibration expiration date, and the calibration certificate number input from the input device. Data including one data is stored in a memory as first data, and data stored in an RFID tag attached to an instrument used to calibrate the instrument is stored in an RFID tag reader Read by the writer, store the read data in the memory as second data, combine the first data and the second data, and combine the combined data with the RFID tag reader / writer It writes in the RFID tag attached to the calibrated meter.

  The RFID tag attached to the instrument used for the calibration includes not only the instrument but also the instrument used for the calibration of the instrument, and further the calibration of the instrument used for the calibration of the instrument used for the calibration. According to the instrument traceability management device of the present invention, the RFID tag attached to a newly calibrated instrument is calibrated for all upstream instruments related to the calibration of the instrument. Will be recorded. Therefore, a traceability system diagram can be easily created by reading out the RFID tag. Further, since data such as a calibration certificate number is stored, the calibration certificate can be easily obtained.

  According to the present invention, it becomes possible to easily create a traceability system diagram of an instrument, and it is possible to easily obtain a calibration certificate.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing an example of the configuration of an instrument traceability management apparatus. In FIG. 1, a meter traceability management device 4 includes a CPU (Central Processing Unit) 41, which is a general information / arithmetic processing device, and a program used by the CPU 41, and a memory used as a work area for the execution. 42, a hard disk storage device 43 used for storing programs and data, an input device 44 composed of a keyboard, a mouse, etc., a display device 45 composed of an LCD (Liquid Crystal Display) display, etc., a tag reader / writer And an interface 46.

  In addition, an RFID tag 2 is attached to the surface of the casing of the instrument 1, and information relating to calibration of the instrument 1 is managed by data stored in the RFID tag 2. Further, the tag reader / writer 3 performs non-contact communication with the RFID tag 2, reads data stored in the RFID tag 2, and writes data to the RFID tag 2.

  On the other hand, the tag reader / writer 3 is connected to a tag reader / writer interface 46. When the tag reader / writer 3 reads data from the RFID tag 2, the CPU 41 reads the data via the tag reader / writer interface 46 and stores it in the memory 42. When the CPU 41 outputs the data stored in the memory 42 to the tag reader / writer interface 46, the tag reader / writer 3 receives the data and writes the data to the RFID tag 2.

  In FIG. 1, the tag reader / writer 3 is an apparatus independent of the instrument traceability management device 4 for the sake of explanation and drawing. However, in the claims, the tag reader / writer 3 is connected to the instrument traceability management device 4. It is supposed to be included. The substance may be either.

  The RFID tag 2 may not be attached to the surface of the meter 1 but may be housed in the housing within a range where communication with the tag reader / writer 3 is possible. Furthermore, the RFID tag 2 may be attached to or stored in a plastic card, for example, and the card may be attached to the instrument 1. In this case, since the card can be carried away from the meter 1, it may be stored and managed in a position away from the meter.

  FIG. 2 is a diagram showing the configuration of the RFID tag. In FIG. 2, an RFID tag 2 is configured by attaching a tag chip 21 made of a semiconductor integrated circuit and an antenna 22 for receiving or transmitting communication radio waves to a thin plate such as plastic as a base. The tag chip 21 includes a power supply unit 211, a CPU 212 that is a small arithmetic processing device, a memory 213 including a nonvolatile memory, and a communication unit 214 that modulates and demodulates the signal of the antenna 22.

  Here, the power supply unit 211 is composed of a stabilized power supply circuit including a charge pump and the like, and generates a predetermined DC voltage required by an internal circuit from a signal received by the antenna 22. In addition, the CPU 212 receives data demodulated from the signal of the antenna 22 by the communication unit 214 and stores the data in the memory 213. In addition, the data stored in the memory 213 is read and output to the communication unit 214. The communication unit 214 modulates the data and outputs it to the antenna as a carrier wave signal.

  In the present embodiment, the memory 213 stores data related to the calibration of the meter 1, and the stored data is referred to as meter tag data or simply tag data in this specification. In addition, storing data in the RFID tag 2 (or storing, recording, or writing) means storing data in the memory 213 of the tag chip 21 of the RFID tag 2. Similarly, when reading data from the RFID tag 2, it means reading data from the memory 213 of the tag chip 21 of the RFID tag 2.

  FIG. 3 is a diagram illustrating an example of fields constituting instrument tag data stored in the RFID tag. In FIG. 3, the instrument tag data 580 includes fields of an instrument identification name, a calibration execution date, a calibration deadline, a calibration target instrument identification name, a calibration certificate number, and a configuration performer. In the first row of the instrument tag data 580, data relating to calibration of the instrument 1 to which the RFID tag 2 is attached is stored. In the case of the example in FIG. 3, the meter identification name is “instrument ABC”, its calibration date is “2004/08/25”, the calibration deadline is “2005/08/24”, and the calibration certification number is “KU1770123” indicates that the constituent implementer is “Kosha”. The calibration target instrument identification name indicates that the instrument is calibrated by the instrument with the instrument identification name. In the example of FIG. 3, it can be seen that the instrument identification names when the calibration target instrument identification name is “instrument ABC” are “standard instrument A”, “standard instrument B”, and “standard instrument C”. That is, it can be seen that “instrument ABC” is calibrated by “standard instrument A”, “standard instrument B”, and “standard instrument C”.

  Here, the “instrument identification name” includes not only a name or model name of an instrument but also an identification number for individually identifying the instrument. In general, in the traceability system diagram or the like, when the instrument used for calibration is shown, it is often sufficient to indicate the name and model name of the instrument. However, when actually tracing the instrument used for calibration, even if it is the same instrument name and the same model name, the actual condition of the calibration is different if the individual instrument is different. There is a need. However, in FIG. 3, for the sake of simplicity, the instrument identification name is represented only by the instrument name.

  FIG. 4 is a diagram schematically showing an example of a traceability system diagram of the instrument. FIG. 4 shows that “instrument ABC” is calibrated by “standard instrument A”, “standard instrument B”, and “standard instrument C”. “Standard instrument A” is shown to have been calibrated by “standard instrument D” and “standard instrument E”, and “standard instrument E” is indicated by “standard instrument X” and “standard instrument Y”. Shown to have been calibrated. Furthermore, “standard instrument X” and “standard instrument Y” are shown to be calibrated with national standard instruments, respectively.

  Such a traceability system diagram 560 can be created based on the instrument tag data 580 shown in FIG. That is, in the present embodiment, the instrument traceability management device 4 reads out data stored in the RFID tag 2 attached to the instrument 1 via the tag reader / writer 3 and displays the traceability system diagram 560 of the instrument 1. Create and output to a printer or the like (not shown).

  FIG. 5 is a diagram showing the configuration of the program and database in the instrument traceability management apparatus. In FIG. 5, the instrument traceability management apparatus 4 includes a tag data read / write control process 51, a tag data display process 52, a tag data update process 53, a tag data storage process 54, an instrument calibration certificate storage process 55, and a traceability system diagram as programs. A display process 56 and the like are provided. The instrument traceability management device 4 includes a necessary standard instrument DB 57, an instrument tag data DB 58, an instrument calibration certificate DB 59, and the like as a database (hereinafter abbreviated as DB). The functions and operations of these programs and databases will be described below.

  The necessary standard instrument DB 57 is a DB that stores instrument names of instruments (standard instruments) necessary for calibrating a certain instrument 1. For example, data of “standard instrument A”, “standard instrument B”, and “standard instrument C” are stored in association with “instrument ABC”. In addition, although the instrument name in this case needs to include the model name of an instrument, it does not need to include an individual identification number. The data stored in the necessary standard meter DB 57 is created for each meter name pair, and is usually input via the input device 44 such as a keyboard before the meter 1 having the meter name is calibrated for the first time.

  The instrument tag data DB 58 is a DB for backing up data written to the RFID tag 2. Therefore, the instrument tag data DB 58 stores the same data as the instrument tag data 580 shown in FIG. Normally, when the instrument 1 is calibrated and the instrument tag data 580 related to the calibration is written into the RFID tag 2, the instrument tag data 580 is added to the instrument tag data DB 58 at the same time.

  The instrument calibration certificate DB 59 is a DB that stores the created or obtained instrument calibration certificate in a file such as image data. An instrument calibration certificate obtained from another company is usually a certificate written on paper, and is read by an input device 44 such as an image scanner and stored in a file such as image data. The instrument calibration certificate issued by the company can be created by a general document creation program, and is stored in accordance with the file format defined by the document creation program.

  The DBs 57, 58 and 59 described above are usually configured on the hard disk storage device 43.

  In FIG. 5, tag data read / write control processing 51 is a program for performing control to read data from the RFID tag 2 and write data to the RFID tag 2 via the tag reader / writer interface 46 and the tag reader / writer 3. .

  The tag data display process 52 is a program for displaying the instrument tag data 580 read from the RFID tag 2 on a display device such as an LCD display. The tag data display processing 52 also executes processing for displaying a meter calibration certificate and starting the traceability system diagram 56 as appropriate based on the displayed contents. Details of these processes will be described separately with reference to FIG.

  The tag data update process 53 is a program for supporting the calibration work of the meter 1 to be calibrated. The tag data update processing 53 displays a list of standard instruments used for the calibration before the calibration is performed, reads the data of the RFID tag 2 attached to the standard instrument, and whether the calibration period has expired. Check etc. Further, after the calibration, new instrument tag data 580 is created based on the calibration result, the data is written to the RFID tag 2 of the instrument 1, and the tag data storage process 54 is started to store the data as an instrument tag. Processing such as addition to the data DB 58 is executed. Details of these processes will be described separately with reference to FIG.

  The tag data storage process 54 is a processing program that is activated by the tag data update process 53 and adds the instrument tag data 580 to be written to the RFID tag 2 to the instrument tag data DB 58. The tag data storage process 54 is also activated by a click input from the input device 44. In this case, the instrument tag data 580 of the instrument 1 stored in the instrument tag data DB 58 is read and stored in the instrument 1. A process of writing to the attached RFID tag 2 is executed. Details of these processes will be described separately with reference to FIG.

  The instrument calibration certificate storage process 55 is a program for storing the instrument calibration certificate created by the tag data update process 53 or the instrument calibration certificate input from the input device 44 in the instrument calibration certificate DB 59. The traceability system diagram display process 56 is a program that is activated by the tag data display process 52 and displays the instrument tag data 580 read from the RFID tag 2 on the display device 45 such as an LCD display.

  The programs 51 to 56 described above are usually stored in the hard disk storage device 43 (see FIG. 1), loaded into the memory 42 at the time of execution, and executed by the CPU 41.

  FIG. 6 is a diagram showing an example of an initial display screen displayed on the display device when the instrument traceability management device is activated. When the instrument traceability management device 4 is powered on, for example, an instrument traceability management processing program is first activated (not shown in FIG. 5). As shown in FIG. 6, the instrument traceability management processing program displays a tag data display, tag data update, tag data addition / restoration, instrument calibration certificate input, traceability system diagram display and end buttons on the display screen of the display device 45. indicate.

  The user sees this display screen and clicks the button to start the program associated with the screen. Here, tag data display processing 52 is performed for the tag data display button, tag data update processing 53 is performed for the tag data update button, tag data storage processing 54 is performed for the tag data addition / repair button, and an instrument calibration certificate input button. Is associated with an instrument calibration certificate storage process 55, and a traceability system diagram display button is associated with a traceability system diagram display process 56, respectively. The end button is associated with a process (not shown in FIG. 5) that erases the initial display screen and ends the instrument traceability management process.

  FIG. 7 is a diagram showing the flow of the tag data display process. In FIG. 7, the CPU 41 of the instrument traceability management device 4 first reads the tag data (instrument tag data 580) of the RFID tag 2 attached to the instrument 1 via the tag reader / writer interface 46 and the tag reader / writer 3. (Step S01), the tag data is stored in the memory 42.

  Next, the CPU 41 displays the tag data stored in the memory 42 on the display device 45 (step S02). For example, the field name is displayed on the top line as in FIG. 3, and the tag data is displayed as it is on the following line. However, for example, when the calibration period of the meter 1 has expired, alarm display such as blinking display or red display is performed on the data. Note that a traceability system diagram button and an end button are displayed in the corner of the display screen (not shown) on the screen for performing this display.

  Next, when an instrument identification name is selected and clicked in a state where the instrument tag data 580 as shown in FIG. 3 is displayed (Yes in step S03), the CPU 41 proofs calibration of the instrument 1 of the instrument identification name. The certificate is read from the instrument calibration certificate DB 59, and the calibration certificate is displayed on the display device 45 (step S06). When the calibration certificate to be displayed is not in the instrument calibration certificate DB 59, a message indicating that there is no calibration certificate is displayed.

  In step S03, if the instrument identification name is neither selected nor clicked (No in step S03) and the traceability system diagram button is clicked (Yes in step S04), the tag data stored in the memory 42 is stored. Based on this, a traceability system diagram 560 as shown in FIG. 4 is displayed (step S07).

  In step S04, if the traceability system diagram button is not clicked (No in step S04) and the end button is clicked (Yes in step S05), the process of the tag data display process 52 is ended. If the end button is not clicked (No in step S05), the process returns to step S03 to wait for a new click input.

An end button is displayed on the screen displayed by each of the calibration certificate display process (step S06) and the traceability system diagram display process (step S07). When the end button is clicked, the respective display screens are closed, and the calibration certificate display process (step S06) and the traceability system diagram display process (step S07) are ended.
Return to step S02.

  By executing the tag data display processing 52 described above, the user can freely browse the tag data of the RFID tag 2 of the meter 1 and can check the calibration deadline. Further, the traceability system diagram 560 of the meter 1 can be browsed immediately, and further, the calibration certificate of the standard meter relating to the calibration of the meter 1 or the meter 1 can be browsed. If the calibration certificate of the standard instrument is not in the instrument calibration certificate DB 59, the calibration certificate can be easily obtained from the calibration certificate number and the data of the calibration operator.

  FIG. 8 is a diagram showing the flow of the tag data update process. The tag data update process 53 is a program that supports the calibration worker to perform the calibration work.

  In FIG. 8, the CPU 41 of the instrument traceability management device 4 first reads out the tag data of the RFID tag 2 attached to the meter 1 to be calibrated via the tag reader / writer interface 46 and the tag reader / writer 3 (step S11). ) And store the tag data in the memory 42. Then, the CPU 41 reads a list of necessary standard instruments corresponding to the instrument identification name of the calibration target instrument 1 from the necessary standard instrument DB 57, and displays the necessary standard instrument list on the display device 45 (step S12).

  The calibration operator looks at the displayed list of necessary standard instruments, and prepares one standard instrument (step S13). Then, the tag reader / writer 3 is used to read the tag data of the RFID tag 2 of the standard instrument. Then, the CPU 41 reads the tag data of the RFID tag 2 of the prepared standard instrument via the tag reader / writer 3 and the tag reader / writer interface 46 (step S14), and stores the read tag data in the memory 42.

  Next, referring to the read tag data, it is determined whether the prepared standard meter is a meter necessary for calibration of the meter 1 or whether the calibration time limit has expired (steps S15 and S16). As a result, if the meter is not necessary for calibration (No in step S15), or if the calibration deadline has expired (No in step S16), an alarm message indicating that the prepared standard meter is not usable. Is displayed on the display device 45 (step S27), and the process returns to step S13. On the other hand, if the prepared standard instrument is a standard instrument necessary for calibration and the calibration deadline has not expired (Yes in step S15 and Yes in step S16), the prepared standard instrument can be used. A message indicating that it exists is displayed on the display device 45 (step S17).

  Next, when the calibration operator confirms the message indicating that the standard instrument can be used, calibration is performed (step S18). When the calibration work is completed, the calibration worker inputs the calibration result (pass or fail data) from the input device 44. The CPU 41 reads input calibration result data (step S19), and stores the data in the memory 42 in association with the identification name of the standard instrument used. And CPU41 determines whether it calibrated using all the required standard instruments displayed on the required standard instrument list in step S12 (step S20). As a result, if there remains a standard instrument to be used for calibration (No in step S20), the process returns to step S13, and the operator prepares a standard instrument that has not yet been used for calibration (step S13). ). And CPU41 performs the process after step S14 again.

  On the other hand, if it is determined in step S20 that calibration has been performed using all necessary standard instruments (Yes in step S20), calibration is performed for all standard instruments with reference to the memory storing calibration result data. It is determined whether or not the processing has been correctly completed (passed) (step S21). As a result, if calibration has not been correctly completed (passed) in any of the standard instruments (No in step S21), a calibration failure alarm message is displayed on the display device 45 (step S28), and tag data The update process 53 is terminated.

  If it is determined in step S21 that calibration has been correctly completed (passed) in all standard instruments (Yes in step S21), the CPU 41 creates a calibration certificate for the calibration target instrument 1 (step S21). Step S22). In creating the certificate, the CPU 41 uses the tag data read from the RFID tag 2 attached to the standard instrument in step 14.

  Next, the CPU 41 updates tag data to be written to the RFID tag 2 attached to the meter 1 to be calibrated (step S23). The update is performed as follows. (1) The tag data read from the RFID tag 2 of the standard instrument used for calibration in step S14 (all tag data is configured as the instrument tag data 580 in FIG. 3) is stored in the memory 42. Combine all with. (2) In the combined tag data, data corresponding to the top row data of the tag data read from the RFID tag 2 of each standard instrument is extracted. (3) Of the data corresponding to the data in the top row, the instrument identification name of the calibration target instrument 1 is stored. Here, the meter identification name of the meter 1 to be calibrated is obtained from the meter identification name field in the top row of the tag data read from the RFID tag 2 of the meter 1 to be calibrated in step S11. (4) Add the top row to the data obtained as described above. The meter identification name field in the top row is the meter identification name of the meter 1 to be calibrated, and the data in the calibration execution date, calibration deadline, and calibration performer fields are stored according to the data entered by the calibration operator. Alternatively, the instrument traceability management device 4 may store the data according to calendar data built in the device. The calibration certificate number stores the calibration certificate number of the calibration certificate created in step S22.

  The tag data updated as described above is written into the RFID tag 2 attached to the meter 1 to be calibrated (step S24). At the same time, the updated tag data is registered in the instrument tag data DB 58, thereby updating the instrument tag data DB 58 (step S25). Then, the instrument calibration certificate DB 59 is updated by registering the instrument calibration certificate created in step S22 in the instrument calibration certificate DB 59 (step S26), and the tag data update process 53 is terminated.

  In the above processing, data obtained by combining all the calibration result data of the calibration target meter 1 and the tag data read from the RFID tag 2 of the standard meter used for calibration is pasted to the calibration target meter 1. The data is written to the RFID tag 2, but only changed data may be written. In that case, for example, the tag data (old tag data) read from the RFID tag 2 of the calibration target instrument in step S11 and the new data created for updating the tag data in step 23 (that is, the calibration target) Compare the data of the calibration result of the instrument 1 and the tag data read from the RFID tag 2 of the standard instrument used for calibration), and delete the data in the old data from the new data, This is the update tag data in this case. Then, the updated tag data is additionally written to the RFID tag 2 of the calibration target instrument.

  By executing the tag data update processing 53 described above, the calibration operator can check the calibration deadline of the standard instrument used for calibration, and is attached to the calibration target instrument 1 based on the calibrated result. It is possible to easily update the tag data in the RFID tag 2 that is present. Furthermore, a calibration certificate for the calibrated meter 1 can be created.

  FIG. 9 is a diagram showing the flow of the tag data storage process. The tag data storage process 54 is activated when the tag data update process 53 is activated in step S25 (see FIG. 8) and when the tag data addition / repair button is clicked on the display screen of FIG. Therefore, the CPU 41 of the instrument traceability management device 4 determines where the program is started from in FIG.

  First, when the tag data is updated, that is, when activated in step S25 of the tag data update process 53 (Yes in step S31), the CPU 41 receives the updated tag data from the tag data update process 53 program (step S32). The received tag data is registered in the instrument tag data DB 58 to update the instrument tag data DB 58 (step S33), and then the tag data storage process 54 is terminated. Here, the old tag data corresponding to the updated tag data is deleted, but may not be deleted.

  If the tag data storage process 54 is activated when the tag data addition / restoration button is clicked, the CPU 41 further generates, for example, a pop-up window and selects whether to add data or repair data. The message is displayed on the display device 45 (not shown). Therefore, when the operator inputs to select tag data addition (Yes in step S34), the worker further inputs data corresponding to the instrument tag data 580 of FIG. 3 from the input device 44 such as a keyboard. input. Such tag data input means is used to input tag data that the standard instrument should have when, for example, a standard instrument to which the RFID tag 2 is not attached is used. Next, the CPU 41 reads new tag data input from the input device 44 into the memory 42 (step S35). Then, the new tag data is added and registered in the instrument tag data DB 58 (step S36), and the execution of the tag data storage process 54 is terminated.

If the tag data storage process 54 is activated when the tag data addition / restoration button is clicked, the CPU 41 further generates, for example, a pop-up window and selects whether to add data or repair data. Display a message (not shown). Therefore, when the operator inputs to select tag data restoration (Yes in step S37),
The CPU 41 further displays a message prompting the input of the instrument identification name of the instrument 1 to which the RFID tag 2 to be repaired is attached (not shown).

  Therefore, when the operator inputs the instrument identification name, the CPU 41 inputs the instrument identification name (step S38) and stores it in the memory 42. Then, using the instrument identification name as a search key, the instrument tag data DB 58 is searched to extract tag data of the instrument identification name (step S39). Further, the CPU 41 writes the extracted tag data to the RFID tag 2 to be restored via the tag reader / writer 3 and the tag reader / writer interface 46 (step S40), and ends the execution of the tag data storage process 54.

  This restoration processing of tag data is provided when the RFID tag 2 attached to the instrument is damaged or when tag data stored in the RFID tag 2 is lost or destroyed. That is, when the tag data stored in the RFID tag 2 is lost or destroyed, the same data stored in the instrument tag data DB 58 can be read and written back to the RFID tag 2. If the RFID tag 2 itself is damaged, a new RFID tag 2 may be attached, the same data stored in the instrument tag data DB 58 may be read and written to the RFID tag 2.
