Description
The invention requests priority of Chinese patent application with the application date of 2022, 10 month and 30 days, the application number of 2022113408827 and the name of' a method and a system for tracing livestock products.
Technical Field
The invention relates to a method and a system for tracing a source of livestock products.
Background
At present, the live pig tracing is not separated from a segmented information management system, and is mainly embodied in three links and two cores. The three links are a live pig breeding and transferring link, a live pig slaughtering and processing link and a live pig circulation and consumption link, so that a service main line of a live pig traceability system is embodied; the two cores are core management means established around the current live pig service main line: the animal quarantine qualification proves electronization, and the animal and animal product identification electronization.
The existing ear tag identification can effectively solve the problem of tracing live pigs from a live pig breeding link and a live pig slaughtering and processing link, but the problem of product identification and tracing information circulation is solved due to the lack of an effective means from the live pig slaughtering and processing link to a live pig circulation link.
The slaughtering link (slaughter house) is used for raising the live pigs in an upward butt joint mode, and the live pigs are in sales circulation in a downward butt joint mode, so that the method is a gateway which is the most critical for the quality safety of the sales circulation of the control pork in the market, and plays a role in supporting the quality safety assurance of the pork.
The existing animal products need to carry the paper animal product quarantine qualification certificate issued by the authorities in the circulation link from slaughtering to market, and are generally divided into a product A certificate and a product B certificate, the circulation is the product A certificate outside the province, the circulation is the product B certificate in the province, the time and the labor are wasted when the paper certificate is distributed, the resources are consumed, and the conditions of mismatching of the material certificates, losing and damaging of the certificate and the like also exist, so that the circulation and inspection of the products are affected. The relevant management department of the present stage advocates the electronic certificate.
The current test point electronic certificate mainly has 3 modes, namely binding an RFID label, binding a paper two-dimension code and spraying and printing a traceability two-dimension code on the carcass skin, and from the aspect of saving, the binding of the RFID label and the binding of the paper two-dimension code both require additional manpower and material resources, because the former inspection and quarantine seal application work still exists, the spraying and printing the traceability two-dimension code on the carcass skin can be combined with the existing inspection and quarantine seal application work, and the manpower is not increased; in addition, binding the RFID tag and binding the paper two-dimensional code requires additional equipment and expense; in addition, the binding RFID tag and the binding paper two-dimensional code are separated from each other by the material evidence, and the material evidence can be integrated by spraying and printing the tracing two-dimensional code on the carcass skin. Therefore, in a comprehensive view, the carcass skin spray printing tracing two-dimensional code is the best mode.
Fig. 1 is an application schematic diagram of carcass skin spray printing traceability two-dimensional codes. The inner side of the surface of the pig carcass split 2 is provided with a baffle plate 1 for stabilizing the movement and the gesture of the pig carcass split 2. The outer side of the surface of the pig carcass split 2 is provided with a code spraying machine 4 and a nozzle 3 of the code spraying machine 4, and the code spraying machine 4 comprises the nozzle 3, a height-fixed roller and a synchronizing wheel. Because pork epidermis is uneven and the thickness of pork also is different, when pig carcass binary solid 2 moves to spouting a yard marking station, through pasting ink jet numbering machine 4 to pig carcass binary solid 2 epidermis outside, then ink jet numbering machine 4 moves down, exerts certain pressure to the epidermis, makes nozzle 3 press close to pig carcass epidermis dynamically to accomplish spouting a yard marking process.
However, the electronic certificate test point is completed by the enterprise, and no corresponding specification exists, so that how the electronic certificate is generated, bound with the livestock product itself, kept consistent with the circulation of the product, and managed with information are fumbling stages. There are also demands or problems, where improvement is complete, how to ensure that data is truly valid, and so on, and the accumulation needs to be explored continuously.
Furthermore, from slaughterhouses to downstream users, the types of users are numerous, including slaughterhouses, official veterinarians, dealers at all levels, consumers, and various government authorities, and therefore special considerations need to be made for different users in the information transfer.

Checking the account of the dealer is mainly whether the history files such as the goods-incoming information, the sales information and the like are complete or not, and whether the goods-incoming and sales matching is carried out or not. Similarly, the related information when the pork product itself is inspected is also related to the corresponding traceability code of the pork product. And verifying the corresponding operation information to be related to the tracing code and uploading the tracing code to the blockchain storage platform.
From the above description, since the circulation from the farm to the slaughterhouse is realized through the electronic ear tag, the circulation from the slaughterhouse to the market is realized through the traceability code and the traceability two-dimensional code which are sprayed on the skin of the pig carcass, the former is a process from scattering to gathering, the latter is a process from gathering to scattering, and the correct circulation of the information of the latter is a key related to the full chain traceability of pork products. The code scanning and evidence searching process from slaughterhouse to market is described in detail below.
1. Code scanning and cable evidence
The distributor scans the traceability code on the purchased pig carcass through the code scanning index APP for a single time, and the quarantine qualified electronic certificate information corresponding to the pig carcass is transferred to the distributor account, which is a common code scanning index behavior.
Because execution errors, such as track dividing errors, input errors, line feeding errors and the like, possibly exist in production sequencing and slaughtering production, errors can be caused to correspond to the slaughtered white strips and owners, and main qualification and white strips are checked when code scanning and evidence searching are carried out, so that the condition of taking wrong meat can be avoided.
Fig. 4 is a basic flow chart of subject qualification checking at the time of code scanning. Firstly, an operator starts code scanning and searching for a card, because the code scanning and searching for a card APP must be firstly logged in by the user, after the user logs in, the identity information, the quantity information, the production information and other information of the ordered pigs can be obtained, so that when the merchant scans the code, the identity information, the production information and the order information of the pigs corresponding to the traceability code can be obtained, whether the white pigs are the pigs ordered by the merchant can be known, if so, the electronic card obtained by scanning the traceability code is searched for, the ticket information of the merchant is transferred into, and meanwhile, the information of the merchant is filled in the electronic card; if not, the electronic certificate is not retrieved and a prompt is given, "you are not the purchaser of the white strip". Through subject qualification, false passes can be avoided or reduced.
2. Batch cable certificate
The pork product distributor has big or small, big one time takes tens hundreds of heads from the slaughterhouse, and small possible one, two white strips, and to the few, the sign of sweeping the sign is relatively easy, and the sign of tracing to the source on the white strip of pig that sweeps its purchase just can, and work load is also not big, but to big user, because the volume of white strip is bigger, and every piece of pork all corresponds a certificate moreover, consequently every piece of pork all sweeps, and work load is bigger like this. For convenience of dealer registration, the continuously coded pig white strips can be carried out in a batch registration mode. The batch sign indicating number is a method for a distributor to obtain a plurality of quarantine inspection qualified electronic tickets by scanning source tracing codes on a first white strip and a last white strip of a continuous spray printing batch of pig white strips respectively, so that the code scanning is carried out twice.
In order to facilitate searching and judging whether the printing is continuous, not only the tracing codes are printed on the white strips of the pigs, but also the sequence numbers are printed at the same time, so that whether a plurality of white strips are continuously printed can be clearly seen, and batch evidence searching is facilitated.
Fig. 5 is a standard stamp spray-printed on a white strip of swine. The standard seal comprises a sequence number 11, a qualified product 12, a quarantine qualified product 13, a tracing code 14 and a tracing two-dimensional code 15. By the sequence number 11 being the sequence number when the white bar is coded, at this time, "1-1" means the left half of the first head, "1-2" means the right half of the first head, and so on. The serial number 11 can be used for judging the serial number of the same day when the serial number is printed in sequence, so that the distributor can conveniently judge whether a plurality of pork slices are continuously sprayed when the distributor takes the pork slices, can conveniently and rapidly locate a certain pork slice, and can conveniently and rapidly find out the record in the evidence-seeking record, thereby rapidly pushing the record to a downstream distributor when the pig white strip corresponding to the record is given to the downstream distributor, and further completing the circulation of the electronic ticket.
As described above, batch billing in the above manner also causes errors in the correspondence of the post-slaughter white strip to the owner. In general, live pigs are slaughtered sequentially according to the declaration sequence of customers, but when the live pigs are slaughtered on a line and the slaughtered white strips are transported through a track, the time division of the track is wrong, so that the pigs of the same customer are not completely together, and the customers distinguish which pigs are through marks on the bodies of the pigs. In order to avoid error check, the number of heads of the check pigs is input in the batch check, or the number of orders of customers in an order system and a slaughter management system and the condition of slaughter production are used for judging whether the batch check is completely correct.
FIG. 6 is a flow chart of batch evidence-checking by quantity. Firstly, operators select batch cable certificates, then, the number X of the batch cable certificates is obtained, the simple method is to input the number of the batch cable certificate pigs, then, the initial pig carcass codes are scanned, the end pig carcass codes are scanned, then, the number Y of electronic certificates between the initial pig carcass codes and the end pig carcass codes is calculated, finally, the number X and the number Y are compared, and if the number X and the number Y are different, the batch cable certificate errors exist. If the number X is the total number, and the cable passes are performed in several times, the number Y of each cable pass is smaller than X, and if the accumulated number of cable passes is larger than X, the cable pass error exists.
FIG. 7 is a flow chart of batch evidence-seeking for verification by order management. Likewise, the operator selects batch of the cable certificates, scans the initial pig carcass code and scans the end pig carcass code, and then judges whether the current cable certificate operator has a request right for all electronic certificates between the initial pig carcass code and the end pig carcass code according to the order management system, the number of production management systems and the client information of the slaughter house slaughter management platform. If the right is not required, the code spraying information of the corresponding pig white strips is given, so that operators can find the pig white strips for processing.
3. Electronic certificate acquisition and distribution
Table 1 is a pig carcass electronic certificate acquisition and distribution record table, and records operation information of the pig carcass corresponding to the electronic certificate. For better illustration of the present invention and the present embodiment, the following is given by way of example. The dealer A receives 10 white strips of 5 pigs from a slaughterhouse through code scanning sign, obtains 6 white strip electronic certificates through batch certificate function scanning 1-1 and 3-2 of code scanning certificate APP, and obtains 4 white strip electronic certificates through batch certificate scanning 14-1 and 15-2. When the customers of the dealer A purchase 1 pork from the dealer A, two operation modes are adopted to complete the correct circulation of goods and electronic ticket information, and the mobile phones of the dealer A, the dealer A and the dealer A are provided with code scanning cable certificates APP.
Table 1 pig carcass electronic certificate acquisition and distribution record table
The first mode is that the distributor A pushes the pork slices with the sequence numbers of 1-1 and 1-2 to Zhang san through the code scanning cable certificate APP in a ticket distributing mode, the pork slices with the sequence numbers of 2-1 and 2-2 are pushed to Lisi through the code scanning cable certificate APP, the information is received on the code scanning cable certificate APP of Zhang san and Lisi, and the Zhang san and Lisi scan the traceability codes on pig carcasses through the code scanning cable certificate APP to confirm and receive goods, so that the coincidence of the material evidence is ensured. The code scanning and evidence-searching operation and pushing operation of the distributor A on the sliced pork, the code scanning and evidence-searching operation and receiving operation of Zhang three and Li four are recorded to the livestock slaughtering and marking platform, and meanwhile, corresponding circulation information is filled in the electronic evidence.
In the second mode, the king five scans the traceability code on the pig carcass through the code scanning cable certificate APP, at this time, the king five cannot obtain the electronic certificates of the pork flakes with the sequence numbers of 14-1 and 14-2, a cable certificate request is sent to the distributor A after the tracing code is scanned, and after the distributor A receives the request, the pork flakes with the sequence numbers of 14-1 and 14-2 are transferred to the king five after confirmation, so that the integration of the material certificates is ensured. Similarly, all operations of the first and the fifth pairs of traceability codes of the dealer can be recorded to the livestock slaughtering marking platform, and corresponding circulation information can be filled in the electronic certificate.
4. Law enforcement verification
The law enforcement inspection comprises animal husbandry and veterinary law enforcement inspection and market supervision inspection, which are respectively completed through animal husbandry and market supervision APP.
The market supervision APP is a tool for daily inspection provided to the market supervision department for law enforcement officials, and provides two functions of meat inspection and archive inspection.
The meat inspection is provided for a basic law enforcement personnel to scan and inspect the pig carcass carrying the electronic seal, check the meat producing area, meat inspection and quarantine information, circulation information and the like, and the quality safety of meat is ensured.
The file checking is provided for basic law enforcement personnel to check the meat operators to check whether the recent goods entering account of the meat operators is abnormal or not, and whether the sold meat meets the quality safety requirement or not. And acquiring the purchase-sale data and the corresponding electronic certificate of the merchant by scanning the two-dimension code of the merchant.
5. Code scanning inquiry
The code scanning inquiry is mainly aimed at common consumers. In the market, after a consumer purchases pork from a dealer, the local food safety public number or applet is used for scanning a merchant two-dimensional code of the dealer or a traceability code on a pig carcass, so that ticket information of the pork is checked.
6. Electronic certificate transfer information recording
The electronic certificate is subjected to a plurality of links from generation to circulation, and comprises operations of generation, code spraying, code scanning and evidence searching, selection and distribution, push receiving or push rejecting, code scanning and detail viewing and the like for each certificate, wherein information associated with each operation is uploaded to a cloud platform, the cloud platform adopts a blockchain technology, written data cannot be tampered, and the read data is consistent with the written data. The information associated with each operation of the electronic certificate comprises a picture corresponding to the operation, operation time, operation place, equipment model used for the operation, operation user information and the like, and the information is an important component part of traceability information and is also the basis of big data analysis.
7. Illegal code scanning operation analysis
The tracing code and the electronic certificate are both digital information, and the material evidence integration is realized by spraying the code onto the skin of the pig carcass, so that the authenticity of the data is ensured.
However, in order to avoid the air-stream transfer of the electronic certificate, the air-stream transfer can be recognized by big data analysis. The space flow is the condition that the tracing code or the tracing two-dimensional code is not matched with the operation action and the operation object. The air circulation mainly comprises the following situations:
1) The electronic certificate is obtained by scanning a picture or a photo. Such recognition can be performed by a picture taken at the time of operation. If the picture background recorded by the code scanning operation is not the pig carcass, the empty stream can be judged.
2) Information such as a time space character at the time of operation is not logical. This can be determined by calculating the time difference and the spatial distance between two adjacent operations to determine whether it is logical, the same person scans two electronic certificates for which there is no possibility of a time-space intersection, and so on.
Finally, it should be noted that: the above embodiments are provided for the purpose of illustrating the technical solution of the present invention by way of conventional breadth and not limitation, and those skilled in the art may make modifications or equivalent substitutions without departing from the spirit and scope of the present invention, and it should be construed that the present invention is covered by the appended claims.
