Description

Technical Field

[0001] This utility model relates to a pig blood code application device and module, belonging to the field of livestock and poultry marking. Background Technology

[0002] According to legal regulations, all animal products must undergo slaughter quarantine before slaughter and distribution. Upon successful quarantine, an official veterinarian from the animal health supervision agency issues an animal quarantine certificate. Taking pigs as an example, currently, after processes such as hot water scalding and rolling friction to remove hair, decapitation, and splitting during transportation, resting, and slaughter, the unique identification information worn by the pigs, such as ear tags and leg bands, falls off. This leads to unclear electronic information regarding the origin and destination of the pork carcasses after quarantine, resulting in problems such as one certificate per batch, low certification efficiency, and discrepancies between the certificate and the actual product. Furthermore, ear tags and leg bands are costly and difficult to widely adopt.

[0003] In order to identify pork carcasses after slaughter, the main method used by slaughterhouses is to imprint blood codes representing the origin and destination of live pigs on the skin during the pre-slaughter selection and trading process. During the slaughter process, the origin and destination of pork carcasses are determined by identifying the blood code information, thus satisfying the traceability of pork product information.

[0004] With the advancement of policies related to paperless animal quarantine certificates and information-based traceability management of agricultural product quality and safety, there is an urgent need to add non-removable and readable identification information to the pre-slaughter resting and selection process of animals. This information is needed to quickly sort pork carcasses on the slaughter production line, generate a unique identification traceability code for each carcass, collect and bind information on the source and destination of the pork carcasses, control the flow of pork carcass products in the slaughterhouse workshop, and facilitate the generation of detailed traceability information for each piece and each head of pork carcass.

[0005] Application number 201811476271.9, entitled "A marking device, system and marking method for livestock carcass skin", discloses a marking device for livestock carcass skin. The device includes a coding unit and a coding unit. The coding unit reads livestock carcass marking data stored locally or on a server and generates a corresponding inkjet image. The coding unit includes an ink nozzle, which sprays the inkjet image onto the livestock carcass skin.

[0006] However, how to apply the blood code, obtain the pig's blood code information, and associate it with the traceability code sprayed on the pig's carcass are all issues that need to be considered. Summary of the Invention

[0007] The purpose of this invention is to provide a blood code application device for live pigs. This device can apply blood codes containing multiple information to the skin of live pigs in an integrated manner. During the slaughtering, production and circulation process, the blood codes on the pig carcasses can be identified to obtain information on the origin and destination of the pig carcasses, thereby improving the efficiency of information technology for pork product traceability codes.

[0008] To achieve this utility model, a device for applying blood codes to pigs is provided, including a slot in which a plurality of character molds are detachably installed. The slot is a double-row slot, with two rows of character molds installed. The double-row slot facilitates the separation of different information, making it easier for the human eye and camera to recognize.

[0009] Furthermore, the double-row slots are equipped with a single clamping bolt, which simultaneously clamps the two rows of lettering.

[0010] Furthermore, the number of the two rows of character patterns is no less than 6.

[0011] This utility model also provides a pig blood code application device, including a slot in which a plurality of character molds are detachably installed, and the number of character molds installed in the slot is not less than 6.

[0012] This utility model also provides a pig blood code application module, the module including a card slot, in which a plurality of character molds are detachably installed, the card slot being a double-row card slot, and the double-row card slot having two rows of character molds installed.

[0013] Furthermore, the double-row slots are equipped with a single clamping bolt, which simultaneously clamps the two rows of lettering.

[0014] Furthermore, the number of the two rows of character patterns is no less than 6.

[0015] By using the device or module of this utility model, multiple pieces of information can be applied in an integrated manner through standardized blood code patterns and coding devices, ensuring that the multiple pieces of information are not confused. Moreover, the application position is fixed, which is convenient for human eyes and machine vision recognition, realizing "item code integration", ensuring meat quality and safety, and ensuring food safety.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The specific implementation scheme of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] To facilitate the application of blood codes, it is necessary to standardize the coding rules for the on-site numbers of slaughterhouse customers, pig suppliers, and meat dealers. Pig suppliers are also known as slaughterhouse operators, and meat dealers are also known as meat vendors. An electronic information file should be established for them in the system.

[0023] The on-site numbering system requires the creation of characters for use on the blood code stamping equipment. After the pigs enter the on-site, the relevant animal certificate number, animal species, and source information of the pig supplier are filled into the system, the selection and transaction process begins. The blood code stamping equipment, which is arranged with the numbering characters of the relevant pig suppliers and meat dealers, is used to stamp the blood code pattern on the skin of the pigs, and the selection and transaction information is uploaded to the slaughter and quarantine coding system. After the meat dealers are selected, the slaughterhouse will allocate them a waiting pen and a pre-cooling room and platform for picking up the meat after slaughter.

[0024] After the pigs are rested in the waiting pen, they enter the slaughter production process. On the slaughter line, video data of the pigs' blood code patterns are collected by cameras. This video data is transmitted to the AI ​​recognition system to identify the blood code patterns, obtain the on-site number information, and transmit it to the slaughter quarantine coding system.

[0025] The on-site numbers of pig suppliers and meat dealers are uploaded sequentially to the slaughter and quarantine coding system. The system automatically processes and associates the transaction information, generates a unique traceability code, and binds the corresponding source and destination information. The source information includes the pig supplier, animal certificate number, and breeding area within the certificate, while the destination information includes the meat dealer and its address. This information serves as the preparatory information for the pork product traceability chain.

[0026] The sequentially generated unique traceability codes are pushed to the inkjet printer, which then sequentially prints the traceability code patterns onto the surface of the pork carcass. At the same time, the printed traceability codes are sent back to the slaughter and quarantine code inkjet printing system. The system then automatically confirms that the traceability code has been printed and used, and associates the traceability code with relevant source and destination information to form a traceability chain.

[0027] Pork carcasses slaughtered on the slaughter line will automatically flow to the corresponding pre-cooling rooms and platforms according to the information of the meat business operators.

[0028] After slaughter, meat dealers take away the pork carcasses. During the distribution process, consumers and regulators can scan the unique traceability code on the carcass skin. Through this traceability code, they can query the slaughter and quarantine coding system and the production, sales and traceability system, and get product certificate information and traceability chain information.

[0029] Table 1 shows the standardized on-site numbering system for live pig suppliers and meat dealers. To facilitate machine or human identification of blood code information and ensure accurate retrieval of pork products after slaughter, it is essential to first establish standardized on-site numbering and coding rules for live pig suppliers and meat dealers.

[0030] 1) If the number of live pig suppliers is relatively small, a two-digit code can be used, or a three-digit or higher code consisting of pure numbers or a combination of alphanumeric letters can be supported, as long as it is unique within a slaughterhouse.

[0031] 2) There are relatively many meat businesses, so a code consisting of one alphanumeric character and three digits can be used. Alternatively, a code consisting of four or more digits or a combination of alphanumeric characters can be used. One alphanumeric character can represent a custom destination area identifier, ensuring that the code is unique within a slaughterhouse.

[0032] Table 1. Standardized On-site Numbering Rules for Live Pig Suppliers and Meat Dealers

[0033]

[0034] Figure 1 and Figure 2 The images show the front and side views of an existing blood code stamping device. The blood code consists of four "B116" typefaces, arranged in a single row, which are inserted into slots on the stamping device. One side of the slot is open for inserting the typefaces; after insertion, bolts on the open side secure them. Different pig suppliers and meat dealers require different typefaces due to their different farm numbers. Changing typefaces simply requires unscrewing the screws, removing the old typeface, and inserting the new one. However, using the single-row typefaces of the blood code stamping device to apply farm numbers to pig suppliers and meat dealers requires separate application, necessitating two stamping steps, which is inefficient; the application points are scattered, hindering camera AI recognition; and the two-step application process is prone to errors.

[0035] Figure 3 and Figure 4The images show the front and side views of the blood code stamping device of this utility model. The blood code stamping device two consists of two rows of lettering templates. The upper row displays the farm number "34" for the pig supplier, and the lower row displays the farm number "B116" for the meat vendor. These are secured with bolts. To replace the lettering templates, simply unscrew the bolts, remove the template, and insert the new one. Using the double-row lettering templates of the blood code stamping device two to apply the farm numbers of pig suppliers and meat vendors requires only one tap, resulting in high efficiency. The two rows of blood codes are positioned together, facilitating AI recognition by the camera, and the error rate during application is low.

[0036] Another method allows for the simultaneous application of the pig supplier's and meat dealer's farm identification numbers in a single tap, by lengthening the slot to accommodate six letter codes, "34B116", or seven letter codes, "34-B116". However, this method requires a relatively long, flat area of ​​pig skin, making it difficult to find the appropriate location and affecting the application quality.

[0037] Figure 5 and Figure 6 These are top and side views of the blood-code typeface. Blood-code typefaces are generally made of aluminum or stainless steel.

[0038] Following the registration process, the selection and trading phase begins. Meat traders arrive at the slaughterhouse to select and purchase pigs from suppliers. After selection, a device is used to imprint blood codes on the pigs' skin, combining characters corresponding to the supplier's number and the trader's number, creating a durable and legible blood code. To facilitate subsequent reading of the blood code information, a standardized pattern is established. The top of the overall blood code pattern displays the supplier's number, and the bottom displays the trader's number. Multiple blood code patterns are imprinted in areas near the pig's back where skin folds are less likely to form after hanging. Simultaneously, during the selection phase, after each trader completes their selection and purchase, the supplier registers the animal entry certificate number, the number of pigs purchased, and the trader's information, reporting this information to the slaughter quarantine coding system and the production, sales, and traceability system. This information is stored for certification purposes.

[0039] Meanwhile, meat vendors confirm the selection process through the system. The system will automatically allocate information such as the pre-cooling room and its platform for picking up meat after slaughter based on the vendors' operating habits. Alternatively, meat vendors can manually fill in the information such as the pre-cooling room and its platform for picking up meat and report it to the system.

[0040] Blood codes consist of letters or numbers and can be recognized using OCR (Optical Character Recognition). OCR refers to the process of analyzing and recognizing image files of text materials to obtain text and version information. In other words, it identifies the text in an image and returns the content in text form. OCR technology is now very mature, especially with the emergence of artificial intelligence-related technologies. OCR has evolved from simple recognition methods such as template matching to the application of various deep neural networks, greatly improving the recognition rate and reducing the false recognition and rejection rates. Today, OCR technology is used in various scenarios such as document and table recognition, license plate and driver's license recognition, card and document recognition, and financial document recognition.

[0041] In addition, it should be noted that besides stamping, blood codes can also be applied using methods such as impact or pressing. Besides being a standalone stamping device, it can also be used as a component of a machine to apply blood codes.

[0042] Finally, it should be noted that the above embodiments are for illustration and not limitation of the technical solutions of this utility model. Those skilled in the art can make modifications or equivalent substitutions to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the protection scope of the claims of this utility model.
