It is an example in the case of using. The system shown in FIG. 6 is basically the same as the first embodiment of the present invention shown and described in FIG. 2, except that a plurality of RFID readers 625 to 629 are connected to the production management terminal. And the point that the cache memory 631 is provided in the storage area 225 of the storage device in the production management terminal 112 is different from the first embodiment.

  Note that the plurality of RFID readers 625 to 629 in the third embodiment are connected via a network or connected to another production management terminal connected to the network. Also good.

  FIG. 7 is a flowchart for explaining the processing operation in the third embodiment of the present invention. Next, this will be explained.

(1) The production management terminal 112 has an RFID reader 625 for reading RFID tags of products and parts, an RFID reader 626 for reading RFID tags of workers, and an RFID reader for reading RFID tags of work processes. The device 628, the RFID reader 629 for reading the RFID tag of the work facility, and the RFID reader 627 for reading the RFID tag of the place are connected, and each RFID reader reads information of the corresponding RFID tag as needed. (Step 701).

(2) It is monitored that the product or part 102 in the middle of production that has flowed on the production line has entered a range that can be read by the RFID reader 217, and the product or part 102 has entered the readable range. When it is detected that the product has arrived, the identification information 108 of the RFID tag attached to the product or component 102 is read (steps 702 and 703).

(3) Next, the production management terminal 112 inquires of the identification information management database 117 for the contents of the read identification information 108 and makes an inquiry to determine whether the read identification information is for a product or a part. (Steps 704 and 705).

(4) If it is determined in step 705 that the read identification information is not for a product or a part, the production management terminal 112 discriminates what information the identification information of the RFID tag is and updates it as needed. While being held, each type is stored in the cache memory 631 in the production management terminal 112, and then the processing returns to step 701 (steps 709 and 710).

(5) If it is determined in step 705 that the read identification information is for a product or part, the production management terminal 112 recognizes that the read information is for a product or part, and this information At the same time, the identification information of the work equipment 104, the work process 105, the work performer 106, and the place 103 held in the cache memory 631 is read (steps 706 and 707).

(6) The production management terminal 112 adds the time information 113 to all the identification information read in the processing of step 707, and identifies the product or part identification information 108, the location identification information 107, the work facility identification information 109, the work Collected information is generated as production management information including process identification information 110, operator identification information 111, and time information 113, and the information is stored in the production management information database 116 via the network 115 (step 708). ).

  FIG. 8 is a diagram for explaining the contents of the cache memory 631 used above. Here, the contents of the cache memory 631 will be explained.

  As shown in FIG. 8, the cache memory 631 stores the type of identification information and the cache value in association with each other. The type of identification information is the place, the work process, the work equipment, the work performer, etc. described above. The cache value is, for example, the section AAA which is the section name in the production system for the place, the B processing process which is the name of the work process for the work process, and the equipment which is the equipment name for the work equipment. Unit C-4, such as employee code XXXX, which is an employee code for the operator.

  According to the third embodiment of the present invention described above, one RFID reader can manage a person to be managed due to problems such as production factory, equipment layout, etc. and performance problems such as RFID readable distance and angle. Even when it is impossible to collectively read RFID tags of products, it is possible to operate the same production management system as in the case of the first embodiment of the present invention described above.

  FIG. 9 is a block diagram showing a configuration of a production system for producing a product having a production management system to which an information collecting method according to the fourth embodiment of the present invention is applied. In FIG. 9, reference numeral 826 denotes a cache memory, and other reference numerals are the same as those in FIG.

  The fourth embodiment of the present invention shown in FIG. 9 is an example suitable for application when there is not much change in the components of the production system. Basically, the fourth embodiment of the present invention shown in FIG. This embodiment is the same as the first embodiment, but is different from the first embodiment in that a cache memory 826 is provided for each RFID type in the storage area 225 of the storage device in the production management terminal 112.

  FIG. 10 is a flowchart for explaining the processing operation in the fourth embodiment of the present invention. Next, this will be explained.

(1) The fourth embodiment of the present invention is a case where there are few variations in the components of the production system, and here, it is assumed that there are relatively few changes in the work process, work equipment, and location. In this case, when the production management terminal 112 is installed, or when any one of the work process, the work facility, and the place is changed, the production management terminal 112 sets each RFID tag that has been changed. The read identification information is stored in the cache memory 826 on the production management terminal 112, and if the worker is engaged in work at a fixed place for a long time, the RFID held by the worker The identification information of the tag 122 is also read when the worker has arrived at the work place, and the information is held in the cache memory 826 on the production management terminal 122 (steps 901 and 902).

  Note that the content of the cache memory 826 used here may be the same as that shown in FIG.

(2) It is determined whether or not the update of the cache 826 by the processing of Steps 901 and 902 has been completed. If not, the processing from Step 901 is repeatedly executed. 112 is in a standby state for reading an RFID tag (steps 903 and 904).

  By performing the processing as described above, it is basically only necessary to read the RFID tag in real time from the RFID tag of the product or component.

(3) Thereafter, the information management terminal 112 determines whether or not the cache 826 needs to be updated. If the cache 826 needs to be updated, the process returns to the processing from step 901 and repeats the processing (step 905).

(4) The production management terminal 112 monitors that the product or part 102 in the middle of production that has flowed on the production line has entered a range that can be read by the RFID reader 114, and puts it in the readable range. When it is detected that the product or part 102 has entered, the identification information 108 of the RFID tag attached to the product or part 102 is read to recognize the product or part (steps 906 to 908).

(5) After that, the production management terminal 112 reads the location identification information 107, the work facility identification information 109, the work process identification information 110, and the work implementer identification information 110 held in the cache memory 826 ( Step 909).

(6) The information read from the cache memory 826 in the process of step 909, the newly read product or part identification information 108 and time information 113 are collected as production management information, and the collected production management information is collected. The data is transmitted and stored in the production management information database 116 via the network 115 (step 910).

  According to the fourth embodiment of the present invention described above, when the frequency of layout, equipment change, worker change, etc. occurring in the production system is low, execution of RFID tag reading processing is minimized. However, the same effects as those of the first embodiment can be obtained.

  FIG. 11 is a flowchart for explaining the processing operation in the fifth embodiment of the present invention. Next, this will be explained.

  The fifth embodiment of the present invention is an example in which identification information collected using an RFID tag can be used for checking consistency with a production work instruction or a production plan. 2 is different from the first embodiment only in that a production plan management database is further provided in the production management system 123 in the first embodiment of the present invention shown in FIG. It is configured.

(1) The basic processing in the fifth embodiment of the present invention executes processing similar to the processing in steps 401 to 408 of the flow shown in FIG. 3 in the case of the first embodiment (step 1101-1108).

(2) After that, as in the case of step 409, the time information 113 is added to the identification information sorted in the process of step 1108, the product or component identification information 108, the location identification information 107, and the work equipment identification information. 109, information that is collected as production management information including work process identification information 110, work performer identification information 111, and time information 113 is generated. At this time, it is not necessary to store the generated production management information in the production management information database 116 (step 1109).

(3) After the processing in step 1109, production of a combination of product or part identification information 108, location identification information 107, work facility identification information 109, work process identification information 110, and work performer identification information 111 is performed. Whether or not the generated production management information is inappropriate by referring to related work instruction information and work plan information using product identification information from the production plan information database provided in this embodiment in the management system 123. Check (step 1110).

  Specifically, the processing in step 1110 includes, for each product, a work process that should not go through or abnormal order through the work process, use of work equipment that does not have a function of performing the work process, This is a process for checking whether there is an inappropriate or unplanned process for a production plan such as execution of work by a work performer who does not have work authority in the work process.

(4) As a result of the check in step 1110, it is determined whether or not an inappropriate process has been performed. If there is no inappropriate process, the process returns to the process in step 1101 and the process from the RFID tag reading standby process is started. Is repeated (step 1111).

(5) If there is an improper process or an unplanned process as a result of the check in step 1110, information on what process has been performed is notified to the worker through the production management terminal 112, and Then, a coping event such as recording that there was an inappropriate process as production management information is started, and then the process returns to the process of step 1101 (step 1112).

  If the check in step 1110 described above is work that involves the incorporation of parts into a product, by referring to work instruction information, work plan information, and design information related to the identification information of the product and parts, It is possible to check whether there is any abnormality in the configuration and work of the product assembly. Specifically, it is to detect whether each product has the planned parts configuration, whether there is an abnormality in the order of parts installation, and whether parts that should not be used have been installed.
