(Embodiment 1)
Hereinafter, a process information collection system according to an embodiment of the present invention will be described in detail with reference to the drawings. The process information collection system according to the present embodiment collects process information of each process on the production line using a tag attached to a work slip used on the production line. The process information is composed of process result information indicating results such as a process name, work start time, work end time and the like in each process, for example.

  As shown in FIG. 1, the process information collection system includes a management terminal device 1 to which a reader / writer 5 for reading and writing a tag is connected, a tag 2, and a plurality of process terminal devices 3. . The management terminal device 1 is connected to a tabulation server (not shown) via a wired LAN (Local Area Network) or a wireless LAN. The process terminal device 3 and the management terminal device 1 are installed, for example, at a manufacturing site managed by a manufacturing department. The aggregation server is held by a management department that indirectly supports a manufacturing department such as a quality assurance department. For example, the management department supports the manufacturing department by feeding back to the manufacturing department the results of performance evaluation of each process obtained by the aggregation server.

  The tag 2 is, for example, a passive tag, and is affixed to a work slip P describing work instructions in each process for manufacturing an article. Thereby, the tag 2 is matched with the articles | goods manufactured by working according to the instruction | indication described in the work slip P in each process. The tag 2 is not limited to a passive tag, and may be an active tag.

  The plurality of process terminal devices 3 are associated with each process (for example, “process 1”, “process 2”,..., “Process N” in FIG. 1) performed on the article. For example, the plurality of process terminal devices 3 are arranged at a place where each process is performed. The process terminal device 3 is, for example, a tablet-type terminal device, and causes the tag 2 to store process result information (first process information) related to the process in accordance with an operation performed by the worker on the process terminal device 3. . As shown in FIG. 2A, the process terminal device 3 connects a CPU (Central Processing Unit) 31, a main storage unit 32, an auxiliary storage unit 33, an input unit 34, a display unit 35, a reader / writer 36, and each unit. The bus 37 is provided. The main storage unit 32 includes a volatile memory such as a RAM (Random Access Memory). This memory is used as a work area for the CPU 31. The auxiliary storage unit 33 has a nonvolatile memory such as a magnetic disk or a semiconductor memory. The auxiliary storage unit 33 stores programs executed by the CPU 31, various parameters, and the like. The auxiliary storage unit 33 includes a process performance information database (hereinafter referred to as “DB”) 331 in which process performance information corresponding to the process terminal device 3 is recorded.

  The input unit 34 is a touch panel, for example. The input unit 34 receives various types of operation information input by a worker on the production line and outputs the received operation information to the CPU 31. The display unit 35 is, for example, a liquid crystal display. The display unit 35 displays various information input from the CPU 31. The reader / writer 36 writes information to the tag 2 or obtains information from the tag 2 by a communication method that conforms to the NFC (Near Field Communication) communication standard, for example.

  The CPU 31 functions as the display control unit 311, the tag detection unit 312, the process performance information acquisition unit 313, and the recording unit 314 by reading the program stored in the auxiliary storage unit 33 into the main storage unit 32 and executing it. The display control unit 311 generates an initial screen or an information input screen for an operator to input process performance information and causes the display unit 35 to display the information input screen.

  The tag detection unit 312 detects that the tag 2 has been deceived by the reader / writer 36 based on the tag detection information notified from the reader / writer 36.

  The process result information acquisition unit 313 acquires the process result information input by the operator by operating the input unit 34 and stores it in the process result information DB 331. For example, as shown in FIG. 3 (A), the process performance information DB 331 includes various process performance information indicating the process name, the worker name, the number of processes, the start time, the end time, and the completed quantity. Stored in association with tag identification information. Here, the process name is a process name associated with the process terminal device 3, and the number of processes indicates the number of repetitions. For example, when “XX process” is repeated twice in the past and this time is the third time, “3” is set. The start time indicates the work start time of the process associated with the process terminal device 3, and the end time indicates the work end time of the process. The completed quantity indicates the quantity of products that have completed the process by performing the target work process. For example, when “XX process” is completed for six products, “6” is set. Here, when the tag detection unit 312 detects that the tag 2 is trapped by the reader / writer 36, the tag identification information of the tag 2 is acquired and stored in the process performance information DB 331. Then, the process result information acquisition unit 313 stores the acquired various process result information in the process result information DB 331 in association with the tag identification information with the tag 2 being held by the reader / writer 36.

  Returning to FIG. 2A, the recording unit 314 acquires the process result information from the process result information DB 331 and records it in the tag 2 while the tag 2 is held by the reader / writer 36. As shown in FIG. 3B, for example, the recording unit 314 includes various process performance information and error detection information indicating status, process name, worker name, process count, start time, end time, and completed quantity as members. Structures to be recorded (hereinafter referred to as “records”) are sequentially recorded. Here, the recording unit 314 records a record in accordance with a format NDEF (NFC Data Exchange Format) defined by the NFC Forum. That is, the recording unit 314 stores the process result information in the tag 2 in association with the error detection information. As error detection information, for example, a checksum, a parity code, a cyclic code, or the like can be employed.

  The management terminal device 1 is, for example, a general-purpose personal computer, and is installed at a location where a work slip is issued or a work slip is collected on a production line. The management terminal device 1 stores initial information in the tag 2 when the work slip is issued, and acquires process result information stored in the tag 2 from the tag 2 when the manufacture of the article is completed and the work slip is collected. As shown in FIG. 2B, the management terminal device 1 includes a CPU 11, a main storage unit 12, an auxiliary storage unit 13, an input unit 14, a display unit 15, and a reader / writer interface (hereinafter referred to as “R / W interface”). 16), a LAN interface 17, and a bus 18 for connecting each part. The auxiliary storage unit 13 includes an aggregation information DB 131 that stores aggregation information used by the user for aggregation. Here, the totaling information is generated by processing the process performance information read from the tag 2. The R / W interface 16 is a serial interface, for example, and is connected to the reader / writer 5. The LAN interface 17 is connected to a wired LAN (Local Area Network) or a wireless LAN. The LAN interface 17 includes a wireless module when connected to a wireless LAN, for example.

  The CPU 11 reads the program stored in the auxiliary storage unit 13 into the main storage unit 12 and executes the program, whereby the tag detection unit 111, the reading unit 112, the error detection unit 113, the tabulation information generation unit 114, the transmission unit 115, and the display It functions as the controller 116. The tag detection unit 111 detects that the tag 2 has been deceived by the reader / writer 5 based on tag detection information notified from the reader / writer 5 via the R / W interface 16. The reader / writer 5 executes writing of information into the tag 2 or acquisition of information from the tag 2 by, for example, a communication method conforming to the NFC communication standard.

  The reading unit 112 reads various process performance information, error detection information, and tag identification information stored in the tag 2 from the tag 2 and stores them in the main storage unit 12. The error detection unit 113 detects an error in various process result information stored in the tag 2 based on the error detection information for each record. When the error detection unit 113 detects an error in the process performance information, the error detection unit 113 notifies the display control unit 116 of process name information (process identification information) indicating a process name corresponding to the process performance information in which the error is detected.

  The tabulation information generation unit 114 generates tabulation information (second step information) from the various process performance information acquired from the tag 2 and stored in the main storage unit 12 and stores the tabulation information in the tabulation information DB 131. Here, for example, as shown in FIG. 3 (C), the tabulation information DB 131 stores various tabulation information indicating processing time and processing time per unit quantity, including a process name, an operator name, a process count, and a completed quantity. It is stored in a form associated with the process performance information shown. Here, the totaling information generation unit 114 calculates the time from the start time to the end time indicated by the process result information as the processing time, and the time obtained by dividing the calculated processing time by the completed quantity is a unit quantity. Calculated as the per-hour processing time. Further, the totaling information generation unit 114 generates totaling information from the process performance information according to the detection result of the error in the process performance information acquired from the tag 2. Specifically, the tabulation information generation unit 114 generates tabulation information from the process performance information other than the process performance information in which an error is detected among the process performance information acquired from the tag 2.

  Returning to FIG. 2B, the transmission unit 115 transmits the aggregation information stored in the aggregation information DB 131 to the aggregation server connected to the LAN via the LAN interface 17. The display control unit 116 generates alarm notification information indicating that the process result information cannot be read from the operation screen or the tag 2 and causes the display unit 15 to display the alarm notification information.

  The display control unit 116 generates a display image and displays it on the display unit 15. When the process name information corresponding to the process result information in which the error is detected is notified from the error detection unit 113, the display control unit 116 causes the display unit 15 to display the process name indicated by the notified process name information.

  Next, the information writing process executed by the process terminal device 3 will be described with reference to FIG. This information writing process is started when, for example, an operator activates an application for executing the information writing process after turning on the power to the process terminal device 3. In addition, when the application is activated, the display control unit 311 displays an initial screen on the display unit 35.

  First, the tag detection unit 312 determines whether or not the tag 2 trapped by the reader / writer 36 has been detected (step S101). If the tag detection unit 312 determines that the tag 2 is not detected (step S101: No), the display control unit 311 continues to display the initial screen on the display unit 35 (step S102), and the process of step S101 again. Execute. On the other hand, when the tag detection unit 312 determines that the tag 2 has been detected (step S101: Yes), the display control unit 311 displays an information input screen for the operator to input various process performance information on the display unit 35. (Step S103). For example, as shown in FIG. 5A, the information input screen is touched when the input field B for inputting various process result information such as the process name and the worker name and the input to the input field B are completed. The button icon EK1 to be displayed is displayed on the display screen 35a of the display unit 35.

  Returning to FIG. 4, next, the process result information acquisition unit 313 determines whether or not the input of the process result information to the information input screen by the operator is completed (step S <b> 104). Here, when the operator touches the part corresponding to the display position of the completion button icon in the input unit 34 after the input of the process result information on the information input screen is completed, the process result information acquisition unit 313 displays the process result information. It is determined that the input of information has been completed. If the process performance information acquisition unit 313 determines that the input of the process performance information is not completed (step S104: No), the process of step S101 is executed again. Here, when the tag 2 is detected by the tag detection unit 312 (step S101: Yes), the information input screen is continuously displayed (step S103). On the other hand, when the operator removes the tag 2 from the reader / writer 36 and the tag detection unit 312 does not detect the tag 2 (step S101: No), the display control unit 311 displays the initial screen on the display unit 35 again. (Step S102). As long as the tag detection unit 312 does not detect the tag 2, the processes in steps S101 and S102 are repeatedly executed.

  Further, when the process result information acquisition unit 313 determines that the input of the process result information is completed (step S104: Yes), the recording unit 314 determines whether or not the process result information can be written to the tag 2. Determination is made (step S105). If the recording unit 314 determines that the process result information cannot be written to the tag 2 (step S105: No), the recording unit 314 issues an alarm notifying that there is a problem in pairing with the tag 2 (step S106). ). Here, the display control unit 311 displays an error screen for notifying the operator of a communication error with the tag 2 on the display unit 35 for a certain period of time upon receiving an alarm. Subsequently, a process of step S108 described later is executed. Here, the display control unit 311 displays the characters “Tag communication error!” On the display screen 35 a of the display unit 35, for example, as shown in the display part I 1 surrounded by the one-dot chain line in FIG.

  Returning to FIG. 4, if the recording unit 314 determines that the process result information can be written to the tag 2 (step S105: Yes), the process result information stored in the process result information DB 331 is stored in the tag 2. Write (step S107). Thereafter, the tag detection unit 312 determines whether or not there is an end instruction (step S108). The termination instruction is issued when the operator performs an operation for terminating the application that performs the information writing process on the input unit 34. If it is determined that there is an end instruction (step S108: Yes), the information writing process ends. On the other hand, if the tag detection unit 312 determines that there is no termination instruction (step S108: No), it executes the process of step S101 again.

  Next, a summary information generation process executed by the management terminal device 1 will be described with reference to FIG. This totaling information generation process is started when, for example, the manager of the production line starts up an application for executing the totaling information generation process after turning on the power to the management terminal device 1.

  First, the tag detection unit 111 determines whether or not the tag 2 deceived by the reader / writer 5 has been detected (step S201). Unless the tag detection unit 111 detects the tag 2 (step S201: No), the standby state is maintained. On the other hand, when the tag detection unit 111 determines that the tag 2 has been detected (step S201: Yes), the reading unit 112 determines whether or not the process performance information from the tag 2 can be read (step S202). ). When the reading unit 112 determines that the process result information cannot be read from the tag 2 (step S202: No), the reading unit 112 issues an alarm notifying that there is a problem in pairing with the tag 2 (step S203). ). Here, the display control unit 116 displays the error information for notifying the administrator of a communication error with the tag 2 on the display unit 15 for a certain period in response to the issue of the alarm. Next, the process of step S210 described later is executed.

  On the other hand, when the reading unit 112 determines that the process result information can be read from the tag 2 (step S202: Yes), the record including the tag identification information, the process result information, and the error detection information is read from the tag 2 ( Step S204). The reading unit 112 stores the records read from the tag 2 in the main storage unit 12 in order. Subsequently, the error detection unit 113 executes error detection processing for detecting an error in information included in the record using the error detection information for each record stored in the main storage unit 12 (step S205). Thereafter, the error detection unit 113 determines whether an error has been detected (step S206). If the error detection unit 113 determines that no error has been detected (step 206: No), the process of step S209 described later is executed. On the other hand, if the error detection unit 113 determines that an error has been detected (step 206: Yes), the error is detected based on the record in which the error is detected and the tag identification information corresponding to the record. A corresponding process is estimated (step S207). The error detection unit 113 notifies the display control unit 116 of the estimated process name and tag identification information corresponding to the record in which the error is detected. Next, the display control unit 116 causes the display unit 15 to display the process name and tag identification information notified from the error detection unit 113 (step S208). The display control unit 116 displays the process name in which an error is detected on the display screen 15a of the display unit 15 as indicated by a display portion P1 surrounded by a broken line in FIG.

  Returning to FIG. 6, subsequently, the totaling information generation unit 114 processes the process performance information included in the records excluding the record in which the error is detected by the error detection unit 113 to generate the totaling information ( Step S209). The tabulation information generation unit 114 generates tabulation information indicating a processing time and a processing time per unit quantity from, for example, process result information indicating a work start time, an end time, and a completed quantity. The aggregation information generation unit 114 stores the generated aggregation information in the aggregation information DB 131. In addition, when the totaling information generation unit 114 completes the generation of the totaling information, the display control unit 116 completes the generation of the totaling information as indicated by a display portion I2 surrounded by a one-dot chain line in FIG. Information for notifying the administrator to the effect is added to the display screen 15a.

  Returning to FIG. 6, thereafter, the tag detection unit 111 determines whether or not there is an end instruction (step S210). The termination instruction is issued when the administrator performs an operation on the input unit 14 to terminate the application that performs the totaling information generation process. If it is determined that there is an end instruction (step S210: Yes), the tabulation information generation process ends. On the other hand, if the tag detection unit 111 determines that there is no termination instruction (step S210: No), it determines whether there is an instruction to read another new tag 2 (step S211). This reading instruction is issued by newly performing an operation for reading process result information from another tag 2 to the input unit 14. For example, when the administrator touches the button icon EK2 on the display screen 15a shown in FIG. 5C, a reading instruction is issued. If the tag detection unit 111 determines that there is no instruction to read a new tag (step S211: No), the tag detection unit 111 executes the process of step S210. On the other hand, if the tag detection unit 111 determines that there is an instruction to read a new tag (step S211: Yes), the tag detection unit 111 executes the process of step S201 again.

  As described above, in the process information collection system according to the present embodiment, the process terminal device 3 stores the process result information associated with the process performed on the article in the tag 2 for management. Terminal device 1 acquires process result information stored in tag 2 from tag 2. Thereby, even in an environment where the process terminal device 3 and the management terminal device 1 are not connected via a network, the process result information of each process can be collected in the management terminal device 1. Therefore, process result information of each process can be collected smoothly at a manufacturing site where the network environment is not sufficiently prepared.

  In the process information collection system according to the present embodiment, the process terminal device 3 stores process result information in the tag 2 in association with error detection information. Then, when the management terminal device 1 detects an error in the process performance information acquired from the tag 2 based on the error detection information, the process name corresponding to the process performance information in which the error is detected is displayed. Thereby, the administrator refers to the process performance information stored in the process performance information DB 331 of the process terminal device 3 of the process indicated by the displayed process name, for example, and confirms the process performance information in which the error is detected. Can do.

  Furthermore, the management terminal device 1 according to the present embodiment generates tabulation information from the process performance information according to the detection result of the error in the process performance information acquired from the tag 2. Specifically, the management terminal device 1 generates information for aggregation from process performance information other than the process performance information in which an error is detected, among the process performance information acquired from the tag 2. As a result, the accuracy of the generated aggregation information is improved, so that the accuracy of performance evaluation of each process by adding the aggregation information is improved.

(Embodiment 2)
In the process information collection system according to the present embodiment, the management terminal device is connected to the tabulation server via the wide area network, and each process terminal device is designated from the tabulation server via the management terminal device. This is different from the first embodiment in that the totaling information is generated and stored in the tag. In the process information collection system according to the present embodiment, not all the process result information in each process is written in the tag, but only the aggregation information designated by the aggregation server is written. This reduces the storage capacity required for the tag.

  As shown in FIG. 7, for example, the process information collection system according to the present embodiment includes a management terminal device 201 for reading and writing a tag 2, a tag 2 attached to a work slip, and a plurality of processes. A terminal device 203. The management terminal device 201 and the process terminal device 203 are, for example, tablet type terminal devices.

The management terminal device 201 and the plurality of process terminal devices 203 are connected via a wireless LAN or a wired LAN. The tabulation server 204 generates tabulation target information indicating the tabulation target necessary for the performance evaluation of the process and transmits the tabulation target information to the management terminal device 201 through the wide area network NT.

  The management terminal device 201 has substantially the same configuration as the management terminal device 1 described in the first embodiment, and is different from the management terminal device 1 in that it does not have an aggregation information generation unit. The management terminal device 201 stores the totaling information acquired from the tag 2 in the totaling information DB 131 as it is. Further, the management terminal device 201 generates a totaling information generation command (command information) that instructs the process terminal device 203 to generate totaling information based on the totaling target information received from the totaling server 204. Then, it is transmitted to each process terminal device 203.

  As shown in FIG. 8, the process terminal device 203 includes a CPU 31, a main storage unit 32, an auxiliary storage unit 33, an input unit 34, a display unit 35, a reader / writer 36, a LAN interface 237, and a bus 38 that connects each unit. . In FIG. 8, the same components as those in Embodiment 1 are denoted by the same reference numerals as those in FIG. In addition to the process performance information DB 331, the auxiliary storage unit 33 includes a command DB 2332 that stores a totaling information generation command, and a totaling information DB 2333 that stores totaling information.

  The LAN interface 237 communicates with the management terminal device 201 via the LAN.

  The CPU 31 reads the program stored in the auxiliary storage unit 33 into the main storage unit 32 and executes it, whereby the display control unit 311, the tag detection unit 312, the process performance information acquisition unit 313, the recording unit 314, and the totalization information generation unit 2315 functions. The tabulation information generation unit 2315 generates tabulation information from various process performance information stored in the process performance information DB 331 in accordance with the tabulation information generation command stored in the command DB 2332. Then, the totaling information generating unit 2315 stores the generated totaling information in the totaling information DB 131.

  Next, the operation of the entire process information collection system according to the present embodiment will be described with reference to FIG. Here, operations of the management terminal device 201 and the three process terminal devices 203A, 203B, and 203C will be described. First, aggregation target information indicating an aggregation target related to a production line desired by the management department is transmitted from the aggregation server 204 to the management terminal device 201 (step S1). In the present embodiment, description will be made assuming that the aggregation target information indicates the processing time in each process and the processing time per unit quantity of the product in each process.

  When receiving the aggregation target information, the management terminal device 201 generates an aggregation information generation command indicating a method for calculating the aggregation target included in the aggregation target information from the process performance information in each process (step S2). Next, an aggregation information generation command is broadcast from the management terminal device 201 to the process terminal devices 203A, 203B, and 203C (steps S3, S4, and S5). Subsequently, each of the process terminal devices 203A, 203B, and 203C stores the received tabulation information generation command in a command DB 2332 described later.

  After that, the process terminal device 203A detects the tag 2 (step S6), and when process result information is input (step S7), generates process information according to the process information generation command stored in the command DB 2332 (step S7). Step S8). Next, the process terminal device 203A writes the generated totaling information to the tag 2 (step S9). Similarly to the process terminal device 203C, the process terminal device 203B detects the tag 2 (step S10), and when process result information is input (step S11), the generation of information for aggregation (step S12), the tag The totaling information is written to 2 (step S13). The process terminal device 203C also executes the processes of steps S14 to S17 in the same manner as the process terminal devices 203A and 203B. Note that the processing contents of steps S14 to S17 are the same as the processing contents of steps S6 to S9. In this way, only the tabulation information generated based on the process performance information is written in the tag 2.

  Next, the totaling information generation / writing process executed by the process terminal device 203 will be described with reference to FIG. This totaling information generation / writing process is started when, for example, an operator activates an application for executing the totaling information generation / writing process after turning on the power to the process terminal device 203. In addition, when the application is activated, the display control unit 311 displays an initial screen on the display unit 35.

  First, the processes of steps S301 to S303 are executed. The contents of the processes in steps S301 to S303 are the same as the contents of the processes in steps S101 to S103 described in the first embodiment. Next, the process performance information acquisition unit 313 determines whether or not the input of the process performance information to the information input screen by the operator has been completed (step S304). If the process performance information acquisition unit 313 determines that the input of process performance information has not been completed (step S304: No), the process of step S301 is executed again.

  On the other hand, when the process performance information acquisition unit 313 determines that the input of the process performance information has been completed (step S304: Yes), the totaling information generation unit 2315 counts based on the process performance information stored in the process performance information DB 331. Business information is generated (step S305).

  Subsequently, the recording unit 314 determines whether or not the totaling information can be written to the tag 2 (step S306). If the recording unit 314 determines that it is impossible to write the totaling information to the tag 2 (step S306: No), it issues an alarm (step S307). Subsequently, the processing after step S309 is executed. On the other hand, when the recording unit 314 determines that the aggregation information can be written to the tag 2 (step S306: Yes), the aggregation information recorded in the aggregation information DB 2333 is written to the tag 2 (step S308). Thereafter, the processing after step S309 is executed. Note that the processing in step S309 is the same as the processing in step S108 described in the first embodiment.

  As described above, in the process information totaling system according to the present embodiment, the management terminal device 201 transmits a totaling information generation command for instructing to generate totaling information from the process performance information via the LAN. It transmits to the terminal device 203. Then, the process terminal device 203 generates tabulation information from the process result information according to the tabulation information generation command, stores the generated tabulation information in the tag 2, and the management terminal device 201 stores the tag 2. Total information is acquired from the tag 2. As a result, the communication load of the LAN connecting the management terminal device 201 and the process terminal device 203 can be reduced, and the totaling information for each process can be collected in the management terminal device 201, thereby improving the usability of the LAN. Can be improved. Further, the storage capacity required for the tag 2 can be reduced by making the size of the totaling information smaller than the size of the process performance information.

  In the process information collection system according to the present embodiment, each process terminal device 203 generates total information, and the management terminal apparatus 201 transmits the total information acquired from the tag 2 to the total server 204 as it is. To do. As a result, the information processing capability required for the management terminal device 201 can be lowered. Therefore, for example, a terminal device having a relatively low information processing capability such as a tablet terminal device can be adopted as the management terminal device 201. it can.

  In the process information collection system according to the present embodiment, the process terminal device 203 stores the totaling information in the tag 2 in association with the error detection information. When the management terminal device 201 detects an error in the tabulation information acquired from the tag 2 based on the error detection information, the process name corresponding to the tabulation information in which the error is detected is displayed. Thereby, the administrator refers to the aggregation information stored in the aggregation information DB 2333 of the process terminal device 203 of the process indicated by the displayed process name, for example, and confirms the aggregation information in which the error is detected. Can do.

  As mentioned above, although each embodiment of this invention was described, this invention is not limited to the structure of each above-mentioned embodiment. For example, when the management terminal device determines that all the processes described in the work slip are completed for the tag 2 attached to the work slip, the information stored in the tag 2 is deleted and the tag 2 is deleted. May be configured to be reusable. In this case, the management terminal device includes, for example, a completion determination unit that determines whether all the processes described in the work slip on which the tag 2 is pasted are completed based on the process result information stored in the tag 2. When the completion determining unit determines that all processes are completed, the information erasing unit may be configured to delete all the process result information stored in the tag 2.

  According to this configuration, all the information stored in the tag 2 is deleted for the tag 2 for which all the processes described in the work slip have been completed. Thereby, the tag 2 can be reused smoothly.

  The management terminal device 1 according to the embodiment stores, for example, a storage determination unit that determines whether or not process performance information is stored in the tag 2, and stores initial information in the tag 2 according to a determination result by the storage determination unit And an initial information setting unit to be configured. Here, if the initial information setting unit determines that the process result information is not stored in the tag 2, the initial information related to the product to be input into the process is stored in the tag 2, and the process result information is stored in the tag by the storage determination unit. If it is determined that the alarm has been made, an alarm may be notified.

  According to this configuration, for example, when the new tag 2 and the used tag 2 are mixed, the new tag 2 can be selected.

  Moreover, the various functions of the process terminal device 3 and the management terminal device 1 according to the present invention can be realized using a normal computer system, not a dedicated system. For example, to a computer connected to a network, a program for executing the above operation is stored in a non-transitory recording medium (CD-ROM or the like) that can be read by a computer system, and the program is distributed to the computer. You may comprise the process terminal device 3 and the management terminal device 1 which perform the above-mentioned process by installing in a system.

  Further, the method for providing the program to the computer is arbitrary. For example, the program may be uploaded to a bulletin board (BBS) on a communication line and distributed to a computer via the communication line. Then, the computer activates this program and executes it like other applications under the control of the OS. Accordingly, the computer functions as the process terminal device 3 or the management terminal device 1 that executes the above-described processing.
