Description

Technical Field

[0001] The present invention relates to the technical field of live pig slaughtering, and particularly to an intelligent quarantine and inspection system for live pig slaughtering. Background Art

[0002] Live pig slaughtering refers to the process of slaughtering live pigs and processing them into pork products. In China, live pig slaughtering is strictly managed and supervised to ensure the quality and safety of pork products.

[0003] Fixed-point live pig slaughterhouses (plants) should establish strict management systems for live pig slaughtering and meat inspection, and prominently display the live pig slaughter operation process flow chart and the meat quality inspection process location diagram in the slaughter workshop. The basic process flow of live pig slaughtering includes fasting and resting the live pigs for at least 12 hours before slaughter, implementing showering, stunning, bleeding, hair removal or skinning, opening the body cavity and cleaning the internal organs (sorting by-products), splitting in half, and trimming, etc.

[0004] Live pig slaughtering is strictly managed and supervised in China to ensure the quality and safety of pork products. There are strict requirements and regulations for the process flow of live pig slaughtering, meat quality inspection, quality standards, and market status, etc., and the management and operation procedures are complex. For this reason, we propose an intelligent quarantine and inspection system for live pig slaughtering. Summary of the Invention

[0005] Based on the technical problems existing in the background art, the present invention proposes an intelligent quarantine and inspection system for live pig slaughtering, which has the characteristics of realizing automatic quarantine and inspection, realizing efficient management, improving processing efficiency, and reducing labor costs, and solves the problems that live pig slaughtering has strict requirements and regulations and the management and operation procedures are complex.

[0006] The present invention provides the following technical solution: An intelligent quarantine and inspection system for live pig slaughtering, including a pre-slaughter shower and ear tag recognition module and a quarantine and inspection module during the slaughter process. In the pre-slaughter shower and ear tag recognition module, when the animal enters the stunning passage, the infrared ray activates the spraying device to start the pre-slaughter shower; when the live pig enters the designated position, the infrared scanner automatically searches for the ear tag to read the livestock identification number, and the livestock identification number read by the system is matched and connected with the hook number of the hanging live pig.

[0007] The quarantine and inspection module during the slaughter process uses an X-ray scanner to scan the animal to check for abnormalities, and at the same time uses a color and shape recognition system to take pictures of the carcass from multiple directions and compare with the pictures already stored in the system to check the integrity and color of the body surface and check for any diseases specified in the regulations.

[0008] Preferably, the slaughter process quarantine inspection module also includes a pathological change detection module, which is used to check whether there are pathological changes in the animal's carcass, heart, lungs, liver, spleen, stomach and intestines, lymph nodes, psoas muscles and kidneys, and whether there is Trichinella spiralis.

[0009] Preferably, the slaughter process quarantine inspection module also includes a preliminary disease confirmation module, which is used to confirm whether the pig is infected with foot-and-mouth disease, African swine fever, swine fever, porcine reproductive and respiratory syndrome, anthrax, or is on the verge of death based on the data from the pathological change detection module during the pre-slaughter inspection.

[0010] Preferably, the preliminary disease confirmation module is used to confirm, during the synchronous quarantine process, whether the corpse is suffering from erysipelas, whether the corpse is suffering from African swine fever, whether the corpse is suffering from foot-and-mouth disease, whether the corpse is suffering from classical swine fever, whether the corpse is suffering from porcine reproductive and respiratory syndrome, whether the corpse is infected with intestinal anthrax, whether the corpse is infected with pharyngeal anthrax, or whether the corpse is infected with trichinella based on the data from the pathological change detection module.

[0011] Preferably, it also includes a module for identifying incoming vehicles and intelligent transcription of quarantine data, which can automatically take photos to identify incoming vehicles; take photos of the pig unloading process and search, scan, and take photos of livestock and poultry identifications and upload them to the system.

[0012] Preferably, the vehicle identification and quarantine data intelligent transcription module for entry uses the identified vehicle and livestock identification information, and the system automatically searches for the corresponding origin quarantine data. The system automatically converts and enters the slaughter information. The entry and exit gate takes a photo of the license plate of the entry vehicle and automatically uploads the photo to the system. The system automatically searches for the vehicle registration and the most recent origin quarantine-related information through the vehicle license plate. The gate automatically opens to allow entry, and no one is allowed to enter without relevant information.

[0013] Preferably, the module for intelligent transcription of incoming vehicle identification and quarantine data automatically takes photos and inputs them into the system during the pig unloading process. All the pigs in this batch enter the pig unloading platform or weighing area. The automated scanning, temperature measurement and photography system counts, measures the temperature and photographs the pigs and uploads the information to the system. The system automatically compares the number of quarantined pigs at the origin with the number of intelligently counted pigs. If the data does not match, the system generates a prompt warning.

[0014] Preferably, the vehicle entry identification and quarantine data intelligent transcription module compares the pig temperature measured by the automatic temperature measuring device with the fixed temperature set by the system. If the body temperature drops or fever occurs, the system instructs the infrared scanning system to generate a measured temperature at the scanning position and generates a prompt warning.

[0015] Preferably, it further includes an intelligent inspection module for animals awaiting slaughter. An intelligent robot is used to conduct inspections on animals awaiting slaughter by verifying the transcribed information during entry inspection and the basic information on the previous inventory. The inspection on animals awaiting slaughter is completed by checking data, measuring body temperature, and comparing photos.

[0016] Preferably, it further includes a quarantine declaration module. The quarantine declaration module submits a quarantine declaration to the slaughterhouse 6 hours before slaughter. The quarantine declaration is completed through the system and includes the quarantine declaration form, the quarantine certificate collected upon entry, and the inspection ledger for animals awaiting slaughter.

[0017] The present invention provides a smart quarantine and inspection system for live pigs. The pre-slaughter shower and ear tag recognition module and the quarantine and inspection module during the slaughter process use an automatic temperature measurement device, a photographing and imaging device, and an X-ray scanning device to detect pathological changes in live pigs. The data comparison device preliminarily determines the type of disease by comparing the obtained pathological change characteristics with the disease identification criteria stored in the data storage device. Finally, the early warning device indicates that a disease has been detected in the live pig quarantine and outputs the type of disease. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 This is the system principle of the present invention Figure 2 . DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 shown, the present invention provides a technical solution: a smart quarantine and inspection system for live pigs, including a pre-slaughter shower and ear tag recognition module and a quarantine and inspection module during the slaughter process. In the pre-slaughter shower and ear tag recognition module, when the animal enters the stunning passage, the infrared ray activates the spray device to start the pre-slaughter shower; when the live pig enters the designated position, the infrared scanner automatically searches for the ear tag to read the livestock identification number, and the livestock identification number read by the system is matched and connected with the hook number for hanging the live pig.

[0022] The quarantine and inspection module during the slaughter process uses an X-ray scanner to scan the animal to check for abnormalities. At the same time, it uses a shape and color recognition system to take multi-directional photos of the carcass and compares them with the stored pictures in the system to check the integrity and color of the body surface and to check for diseases specified in the regulations. The system stores data through a data storage device.

[0023] As shown Figure 1 in the figure, the quarantine and inspection module in the slaughter process further includes a pathological change detection module. The pathological change detection module detects the pathological changes of live pigs through an automatic temperature measuring device, a photographing and imaging device, and an X-ray scanning device. Specifically:

[0024] During stunning, use an X-ray scanner to scan the submandibular space and the front of the submandibular gland. Check for swelling, edema, and colloid infiltration, whether the cut surface is brick red, and whether there are necrotic foci (purple, black, yellow), etc.

[0025] Use X-ray to check whether there are transparent cysts the size of soybeans in the bilateral masseter muscles, and cysticerci with scolexes the size of rice grains on the cyst wall.

[0026] Use a shape and color recognition system to take pictures of the carcass from multiple directions, and compare with the pictures stored in the system for the integrity and color of the body surface, and check for skin lesions and joint swelling caused by diseases specified in the regulations; whether there are blisters, ulcers, rotten spots, etc. on the snout and hooves.

[0027] Before taking out the internal organs, use X-ray to observe whether there is fluid accumulation, adhesion, and fibrinous exudate in the thoracic cavity and abdominal cavity. Check whether there is intestinal anthrax in the spleen and mesenteric lymph nodes. After taking out the internal organs, check the heart, lungs, liver, spleen, gastrointestinal tract, etc.

[0028] Check the common pathological changes of the heart: Visually inspect the pericardium, cut open the pericardium, and check for degeneration, pericardial effusion, fibrinous exudate, congestion, hemorrhage, necrosis and other lesions. Longitudinally dissect the heart at the atrioventricular boundary on the posterior margin of the heart parallel to the left longitudinal groove to check the endocardium, myocardium for tiger spot heart and parasites, blood coagulation state, and whether there are cauliflower-like vegetations on the mitral valve, etc.

[0029] Check the common pathological changes of the lungs: Visually inspect the shape, size, and color of the lungs, palpate the elasticity, and check for necrosis, collapse, edema, congestion, consolidation, nodules, fibrinous exudate and other lesions in the lung parenchyma. Use X-ray to check the bronchial lymph nodes for hemorrhage, congestion, swelling, necrosis, etc. When necessary, dissect the trachea and bronchi.

[0030] Check the common pathological changes of the liver. Visually inspect the shape, size, and color of the liver, palpate the elasticity, and check for congestion, swelling, degeneration, jaundice, necrosis, sclerosis, tumors, nodules, fibrinous exudate, parasites and other lesions. Dissect the hepatic hilar lymph nodes to check for hemorrhage, congestion, swelling, necrosis, etc. When necessary, dissect the bile duct.

[0031] Check the common pathological changes of the spleen. Visually inspect the shape, size, and color, palpate the elasticity, and check for significant swelling, congestion, darkening of color, brittleness of texture, necrotic foci, marginal hemorrhagic infarction, elevation of the capsule and adhesion and other lesions. When necessary, dissect the spleen parenchyma.

[0032] Check for common pathological changes in the stomach and intestines. Visually inspect the gastrointestinal serosa to observe its shape and color, and check for congestion, bleeding, necrosis, jelly-like exudate, and adhesion. Make an incision of no less than 20 cm in length on the mesenteric lymph nodes to check for enlargement, edema, congestion, bleeding, necrosis, and other lesions. If necessary, dissect the stomach and intestines to check for congestion, bleeding, edema, necrosis, and ulcers on the mucosa.

[0033] Overall examination: Check the skin, subcutaneous tissue, fat, muscles, lymph nodes, bones, and chest and abdominal serosa for congestion, bleeding, rashes, abscesses, and other abnormalities.

[0034] Check for common pathological changes in lymph nodes. Open the superficial inguinal lymph nodes on both sides to check for congestion, swelling, hemorrhage, necrosis, hyperplasia and other lesions. If necessary, dissect the deep inguinal lymph nodes and internal iliac lymph nodes.

[0035] Check for common pathological changes in the lumbar muscles. If the masseter muscle is abnormal, make an incision of about 10 cm along the muscle fibers on both sides of the junction of the sacral vertebrae and lumbar vertebrae to check for cysticercus.

[0036] Check for common pathological changes in the kidneys. Peel off the renal capsules on both sides, visually inspect the shape, size, and color of the kidneys, touch the texture, and check for anemia, bleeding, congestion, swelling, and other lesions. If necessary, longitudinally dissect the kidneys and check for color changes, bleeding, and bulges in the cortex and medulla of the cut surface.

[0037] Trichinella inspection. Take about 30g of each of the left and right diaphragmatic legs, number them the same as the carcass, and place the diaphragmatic legs with the muscular membrane torn off under a 50x camera to check whether there are Trichinella cysts similar to the pictures in the library (willow-leaf-shaped meat silk patterns, spiral-shaped worm body). If a suspected sample is found, an early warning will be prompted.

[0038] like Figure 1 As shown, the slaughter process quarantine inspection module also includes a preliminary disease confirmation module. The preliminary disease confirmation module uses a data comparison device to obtain the pathological change characteristics and the disease identification standards in the data storage device to preliminarily determine the type of disease. Finally, the early warning prompt device prompts the quarantine of the pig to have a disease and outputs the type of disease at the same time.

[0039] Specifically: ante-slaughter inspection, preliminary determination of the disease type based on clinical symptoms:

[0040] 1. The body temperature rises to 40-42℃, and fever, lack of energy, loss of appetite and drooling occur; blisters appear on the crown, fork and heel of the hoof, and the surface bleeds after the blisters rupture, forming dark red spots. The infection causes suppuration, necrosis, shedding of the hoof shell, and inability to get up from the ground; blisters and erosions appear on the nasal disc, oral mucosa, tongue, and udder, and foot-and-mouth disease is suspected.

[0041] 2. High fever occurs, with body temperature reaching 42°C, lassitude, loss of appetite, listlessness; vomiting, constipation, with blood and mucus covering the surface of the feces, or diarrhea, with bloody feces; visible mucous membranes are flushing and cyanotic, and there are mucopurulent secretions in the eyes and nose; there are bleeding points on the skin of the ears, limbs, and abdomen; ataxia, stiff gait, dyspnea or other neurological symptoms; pregnant sows have symptoms such as miscarriage; or sudden death without symptoms occurs, suspecting African swine fever infection.

It is initially determined that the carcass is infected with porcine reproductive and respiratory syndrome.

[0053] 6. Centered on the lymphoid tissue of the duodenum and jejunum, on the basis of mucosal congestion and hemorrhage, focal lesions are formed. Initially, they are red, round elevations, clearly demarcated from the surrounding area, covered with fibrin on the surface, and then necrosis occurs. The necrosis can reach the submucosa, forming a solid membranous grayish-brown scab, and the surrounding tissues and mesentery show hemorrhage. Similar lesions can also be seen in the mesenteric lymph nodes. There is red fluid in the abdominal cavity. The spleen is swollen and soft, and the kidneys are congested or hemorrhagic. It is suspected of being infected with intestinal anthrax.

[0056] As Figure 2 shown, it also includes an intelligent transcription module for identifying incoming vehicles and quarantine data. The intelligent transcription module for identifying incoming vehicles and quarantine data automatically takes pictures of vehicles when they enter the farm; during the pig unloading process, pictures are taken, searched, scanned, and the livestock identification is photographed and uploaded to be connected with the intelligent livestock and veterinary system. Through the identified vehicle and livestock identification information, the system automatically searches for the corresponding local quarantine data system and automatically converts and enters (generates) slaughter information. The entrance and exit barriers take pictures and identify the license plates of incoming vehicles, and the pictures are automatically uploaded to the Hubei Intelligent Livestock and Veterinary System. The system automatically searches for the vehicle filing and relevant information on the most recent local quarantine associated with the vehicle license plate through the vehicle license plate, and the barrier automatically opens for release. Vehicles without relevant information are not allowed to enter. During the pig unloading process, pictures are automatically taken and input into the Hubei Intelligent Livestock and Veterinary System. All pigs in this batch enter the pig unloading platform or the weighing area. The automated scanning, temperature measurement, and picture-taking system counts, measures the temperature, and takes pictures of this batch of pigs and uploads this information to the intelligent livestock and veterinary system. The system automatically compares the number of pigs in the local quarantine with the number counted by the intelligent counting system. If the data does not match, the system generates a prompt warning. When comparing the measured temperature of the pigs with the fixed temperature set in the system, if the body temperature drops or there is a fever, the system commands the infrared scanning system to generate the measured temperature at the scanning position and generates a prompt warning. The automatic scanning device searches for the livestock identification, scans the livestock identification number (currently, 5% search is considered qualified due to factors such as light, cleanliness, wear, search technology, and frequent movement of pigs), and takes pictures and uploads them to the intelligent livestock and veterinary system. The system compares the newly identified livestock identification number with the livestock identification number in the local quarantine certificate. If the comparison result is abnormal, the system generates a prompt warning. Based on the system's temperature measurement, counting, and livestock identification scanning results, the system generates new data. When the vehicle license plate, pictures during the pig unloading process, and livestock identification pictures and relevant data are compared and found to be correct, the system automatically completes the arrival confirmation. After the entrance inspection is completed, the pigs enter the waiting-for-slaughter process (waiting-for-slaughter pen) through the designated channel.

[0057] As Figure 2As shown, it also includes an intelligent waiting-to-slaughter inspection module, which conducts waiting-to-slaughter inspection work through the entry of intelligent robots to check transcription information and basic information such as previous inventory. The waiting-to-slaughter inspection is mainly completed by checking data, measuring body temperature, and taking photos for comparison. The intelligent robot inspects once every four hours. The inspection timing method starts from the last batch of animals declared for quarantine entering the slaughter procedure, and the first inspection starts, and the inspection is conducted every four hours. The inspection content includes counting the number of heads, health checks, etc. The intelligent robot compares the data of the corresponding pens saved in the system through intelligent points. If there is a change in data, such as escape, the system automatically prompts an early warning; if stress or mechanical damage requires urgent slaughter, the relevant information is manually entered. The intelligent robot searches and emits several infrared temperature measurement signals at a relatively fixed ear root, measures the body temperature and returns it to the system while recording the measurement results. If the measured temperature is compared with the fixed temperature set by the system and the body temperature drops or fever occurs, the system instructs the infrared scanning system to record the measured temperature at the scanning position and generate a prompt early warning. The robot takes photos of the pigs and the ground of the pens and compares them with the existing data in the system (physical and mental state, body temperature, respiration, skin, hair, visible mucous membranes, chest, abdomen and surface lymph nodes, excretion movements and excrement characteristics, etc.), finds out suspected sick pigs through comparison, and preliminarily determines the type of animal disease based on typical symptoms such as body temperature, respiration, movement, skin, hair, visible mucous membranes, chest, abdomen and surface lymph nodes, excretion movements and excrement characteristics. The system classifies the preliminarily judged animal diseases according to the list of zoonoses and the first, second and third category animal diseases, and gives prompt warnings. The practicing veterinarian or animal epidemic prevention technician of the slaughterhouse will conduct on-site inspections and verifications based on the warning information and handle it in accordance with regulations. The inspection time, the roll number to be slaughtered, the number of pigs, the inspection results and the warning information are automatically saved.

[0058] like Figure 2As shown in the figure, it also includes a quarantine declaration module. The slaughterhouse (plant) submits a quarantine declaration 6 hours before slaughter. The quarantine declaration is completed through an intelligent system. When submitting the quarantine declaration, a quarantine declaration form, the quarantine certificate recovered upon entry, and the ledger of inspections during the period of waiting for slaughter are submitted. The official veterinarian determines whether to accept the declared quarantine based on: the animal quarantine certificate attached when the live pigs enter the slaughterhouse; the records of inspection upon entry and inspections during the period of waiting for slaughter. Declaration acceptance: After receiving the quarantine declaration, the animal health supervision institution reviews the declaration materials. If the materials are complete, it shall be accepted. Two hours before slaughter, the official veterinarian stationed at the slaughterhouse (plant) issues an order, instructing the intelligent quarantine system to conduct clinical inspections in accordance with the methods of local quarantine. The clinical inspections are mainly completed through comprehensive analysis in multiple aspects such as measuring body temperature, observing the body surface, excretory movements, the characteristics of excreta, and the movement state. The intelligent detection system emits infrared rays to detect heat sources, and the number of heat source points is counted as the number of live pigs. If the temperature of the heat source point is higher or lower than the system-set value, it is saved as suspected data and retained for comprehensive judgment and application. The robot takes pictures of the live pigs and the floor of the pens and compares them with the existing data in the system (physical and mental conditions, body temperature, respiration, skin, hair, visible mucous membranes, chest, abdomen, and superficial lymph nodes, excretory movements, and the characteristics of excreta, etc.). By comparing, suspicious diseased pigs are found. Based on the typical symptoms such as body temperature, respiration, movement, skin, hair, visible mucous membranes, chest, abdomen, and superficial lymph nodes, excretory movements, and the characteristics of excreta, the types of animal diseases suffered are initially determined. The system classifies the initially judged animal diseases according to the list of zoonotic diseases and animal diseases of Class I, Class II, and Class III, and gives a prompt warning. The official veterinarian conducts on-site inspections and verifications based on the warning information and handles them in accordance with the regulations. The official veterinarian for pre-slaughter quarantine, the quarantine time, the waiting-for-slaughter roll number, the number of live pigs, the quarantine results, and the warning information are automatically saved by the system. When conducting quarantine declaration, the official veterinarian recovers and saves the electronic quarantine certificate through the system for the quarantine certificate submitted by the slaughterhouse (plant), and uploads the relevant information to the animal quarantine management information system to complete the arrival verification process.

[0059] Determination of inspection results (diseases specified in local quarantine regulations): Comprehensive judgment based on body temperature, respiration, visible mucous membranes, body surface skin, movement state, characteristics of excreta, etc.

[0060] As Figure 2 As shown in the figure, it also includes a pre-slaughter shower and ear tag identification module. When the animal enters the stunning passage, the infrared ray activates the spraying device to start the pre-slaughter shower. When the live pigs enter the designated position, the infrared scanner automatically searches for the ear tags to read the livestock identification numbers. The livestock identification numbers read by the system are matched and connected with the hook numbers of the hanging live pigs. The new numbers are consistent with the livestock identification numbers, quarantine certificate numbers, and the numbers of carcasses, heads, red viscera, white viscera, and diaphragmatic crura during the slaughter process, ensuring that if there is a problem with one part during quarantine, the other parts can be accurately located.

[0061] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
