And the file of the third hierarchy or the hierarchy after the third hierarchy is a meat product number read from an RFID tag attached to the meat product, IC number, livestock number, and meat product received for carving. It has items such as a certain body number, supplier name, weight, production date, arrival date, shipping date, and part name.
As to which file the data received by the management apparatus 11 is stored in, the received data is stored in a file in the next layer of the file hierarchy having the received original number as the meat number.
[0019]
Next, the marking device 40 will be described with reference to FIG. FIG. 5 is a block diagram showing a configuration of the marking device 40. The marking device 40 includes a CPU 41 that controls each part, a ROM 42 that stores a program that controls the operation of the CPU 41, a RAM 43 that stores flags, registers, or various data, a screen display 44, an operation unit 45, and the Internet. A communication unit 46 that can be connected, a weighing unit 47, a label issuing unit 48, and an RFID reader / writer 49 that reads and writes data from and to the RFID tag using a predetermined communication protocol.
[0020]
Further, as described in Japanese Patent Laid-Open No. 2000-10906, a label with an IC provided with an RFID chip is used for each label, and a communication device that communicates with the RFID chip is built in the label issuing device. It is preferable that the communication with the chip and the label issuance are performed almost simultaneously.
[0021]
Next, a memory map of the RFID tag will be described with reference to FIG. FIG. 6 is a diagram showing an example of a memory map of the RFID tag. This memory map is a 2K bit type (storage capacity is 2K bit), and there are four pages (page 0 to page 3) for each block, and each page is composed of 64 bits. The blocks are from block 0 to block 7. Only page 0 of block 0 is arranged in the ROM 42, and other data is arranged in the RAM 43.
[0022]
In page 0 of block 0, the IC number is stored. This IC number is written in the ROM 42 by the IC manufacturer. The IC number includes a manufacturer number and is a unique number that can identify individual RFID tags.
Block 1 includes items of livestock number, production area, and weight as livestock data. In block 2 to block 4, there are items such as meat product number, trader name, production date, part name, weight, body number, etc. as data of processed and produced meat products.
[0023]
Next, the operation of the marking device 40 will be described with reference to FIG. FIG. 7 is a flowchart showing a schematic operation of the marking device 40. Since the operation of the marking device 40 is controlled by the CPU 41, this flowchart shows the operation of the CPU 41.
[0024]
First, the CPU 41 is in a state of requesting a list of IC numbers (a list of IC numbers stored in the management device 11) of meat products that can be properly received by operating the operation unit 45. It is determined whether or not (step S1).
[0025]
If YES in step S1, the CPU 41 causes the communication unit 46 to transmit a list request signal indicating a list request to the management device 11 (step S2). Next, the CPU 41 takes in the list data sent from the management device 11 to the communication unit 46 and stores it in the RAM 43 (step S3). After step S3, the process returns to step S1.
[0026]
In the case of NO in step S1, the CPU 41 determines whether or not an operation for reading the RFID tag attached to the received meat product has been performed by the RFID reader / writer 49 (step S4).
If YES in step S4, the CPU 41 designates the address of block 0 and page 0 in the RFID tag and reads the IC number (step S5). Next, the CPU 41 determines whether or not the list stored in step S3 has the same IC number as the IC number read in step S5 (step S6). In the case of NO at step S6, the CPU 41 causes the screen display 44 to display an error message indicating that the received meat product is an “unauthorized product” (step S7). After the process of step S7, the process returns to step S1.
[0027]
If YES in step S6, the CPU 41 determines that the received meat product is a “genuine product”, reads all the data stored in the RFID tag and stores it in the RAM 43 (step S9), and The read data is displayed on the screen display 44 (step S10). After the process of step S10, the process returns to step S1.
[0028]
In the case of NO in step S4, the CPU 11 determines whether or not an operation for requesting traceability data (history data) of meat products with RFID tags read in the processing from steps S4 to S10 has been performed on the operation unit 45. (Step S11). In the case of YES in step S11, the CPU 41 transmits the meat product number and the history data request signal in the data stored in step S9 to the management device 11 (step S12). Next, the CPU 41 causes the communication unit 46 to receive the traceability data transmitted from the management device 11 and store it in the RAM 43 (step S13). Next, the CPU 41 displays the contents of the traceability data on the screen display 44 (step S14). It returns to step S1 after the process of step S14.
[0029]
In the case of NO in step S11, the CPU 41 determines whether or not an operation for marking, which is to write data to a new RFID tag attached to the processed and produced meat product, has been performed on the operation unit 45 (step S15). . When YES is determined in the step S15, the CPU 41 determines whether or not the original data that is the traceability data stored in the step S13 is present in the RAM 43 (step S16). If NO in step S16, the CPU 41 causes the screen display 44 to display an error (notification) (step S17). After the process of step S17, the process returns to step S1.
[0030]
If YES in step S16, the CPU 41 causes the weighing unit 47 to measure the processed and produced meat product (step S18). Next, the CPU 41 calculates the total weight of meat products produced from the same raw material (purchased meat food), and whether or not the total weight exceeds the weight value of the raw material stored in step S9 or step S13. (Step S19). In the case of YES in step S19, the CPU 41 causes the screen display 44 to perform an error display (notification) indicating “not matching the original!” (Step S20). After the process of step S20, the process returns to step S1.
[0031]
In the case of NO in step S19, the CPU 41 reads the IC number from the new RFID tag via the RFID reader / writer 49, generates a meat product number that includes the supplier number and can individually identify the meat product, Data to be registered (one of the traceability data) is created by inputting from the operation unit 45 such as a part name. Then, the CPU 41 transmits the meat product number, the IC number, the livestock number, the body number, the trader name, the weight, the production date, the arrival date, the part name, and the like as registration data from the communication unit 46 to the management device 11 ( Step S21).
[0032]
Next, the CPU 41 controls the RFID reader / writer so that data corresponding to items in the memory map of the RFID tag among the data created in step S21 is written to the RFID tag. Further, the CPU 41 prints the meat product number, livestock number, breed, part name, etc. on the label (step S22).
[0033]
Next, the CPU 41 stores the cumulative weight (total weight) of meat products produced from the same raw material in the RAM 43 for each same raw material, which is the value calculated in step S19 (step S23). After the process of step S23, the process returns to step S1.
After the process of step S23, the operator who operates the marking device 40 attaches (or affixes) an RFID tag (which may be a label with an RFID chip) to the produced and processed meat product, thereby completing the marking.
[0034]
If NO in step S15, the CPU 41 performs processing other than the above processing, such as setting, maintenance, or clearing of stored data (step S24). After the process of step S24, the process returns to step S1.
[0035]
Next, the operation of the management apparatus 11 will be described with reference to FIG. FIG. 8 is a flowchart showing a schematic operation of the management apparatus 11.
First, the management device 11 performs various settings for setting the traceability data as Web data (Web page), and allows the traceability data to be viewed from any terminal 50 or the marking device 40 by inputting the URL. (Step S31).
[0036]
Next, the management device 11 determines whether or not a list request signal has been received from a meat producer (a livestock farmer 31, a slaughter / demolition trader 32, a secondary processor 33, a supermarket 34, etc.) (step S32). ). Here, only the sender's IP address is registered as a determination target.
[0037]
In the case of YES in step S32, the management apparatus 11 registers the livestock number of the first layer file shown in FIG. 2 or the meat number in the subsequent layer file as the livestock number or the original number in the lower layer file. The IC number of meat product data that has not been processed, that is, that has not been processed by the next contractor, is extracted from the files of all layers and is used as list data (step S33).
[0038]
Next, the management device 11 transmits the list data to the marking device 40 of the meat producer who requested the list data (step S34). After the process of step S34, the process returns to step S32.
[0039]
In the case of NO in step S32, the management device 11 determines whether or not a request signal for tressurability data (history data) has been received (step S35).
In the case of YES in step S35, if the meat product number is specified in the request for the traceability data, the management apparatus 11 starts from the livestock number of the meat data in the corresponding file, and the meat products of all levels including this livestock number The data is transmitted to the terminal 50 or the marking device 40 that has requested the data. Moreover, if the livestock number is specified in the request for the traceability data, the management device 11 transmits the meat data data of all the corresponding levels to the terminal 50 or the marking device 40 that has requested the data (step S36). After the process of step S36, the process returns to step S32.
[0040]
In the case of NO in step S35, the management device 11 receives registration data from the marking device 40 and determines whether a registration request has been made (step S37).
In the case of YES in step S37, the management device 11 searches all files from the original number in the registration data, and the total weight of all meat products having the same original number and the weight included in the registration data received this time Is added, and it is determined whether or not the value exceeds the weight of the original meat product data (step S38).
In the case of NO in step S38, the management apparatus 11 sets the new meat product data in the file of the next layer of the file layer having the meat number data of the original number based on the registered data, so that the meat product Is registered (step S39). After step S39, the process returns to step S32.
[0041]
If YES in step S38, the management device 11 transmits an “error signal” to the marking device 40 that has requested registration in step S37 (step S40). After the process of step S40, the process returns to step S32.
[0042]
If NO in step S37, the management device 11 performs other processing such as maintenance (step S41). After step S41, the process returns to step S32.
[0043]
Next, the overall operation of the meat traceability system of this embodiment will be described.

The livestock farm 31 attaches the RFID tag to the livestock.
B). Then, the management device 11 stores and registers the data received from the marking device 40 of the livestock farm 31 in the first layer file.
C). The slaughter / demolition operator 32 operates the marking device 40 to make a list request, and receives and records a list of IC numbers of meat products.
[0044]
D). When the slaughter / scraper 32 receives the livestock from the livestock farm 31, the slaughter / demolition operator 32 operates the marking device 40 to read out the IC number of the RFID tag attached to the livestock. When the IC number exists, all data of the RFID tag is read. Here, at least the meat product number and the weight are read out.
[0045]
E). Next, the slaughter / scraper 32 slaughters / scraps the livestock, and cuts and weighs each part. The slaughter / demolition operator 32 operates the marking device 40 to record the history of the original IC number, meat product number, slaughter / demolition company name, production date, arrival date, part name, weight, etc. The additional information is transmitted to the management apparatus 11.
[0046]
F). Then, when the management apparatus 11 receives the data transmitted in the process E), the management apparatus 11 records the data in the second layer file and registers the meat product.
[0047]
G). In the case of a supplier (secondary processor 33, supermarket 34, etc.) after the secondary processing (disassembly processing), the same processing as the processing from C) to F) is performed.
[0048]
H). When looking at the traceability data (history data) of meat products, the arbitrary terminal 50 and the marking device 40 specify a predetermined URL and connect to the management device 11 via the Internet 20 to obtain the livestock number or meat number.
