Description

Technical Field

[0001] This invention relates to the field of mutton processing technology, and in particular to a mutton acid removal regulation system and method. Background Technology

[0002] With the improvement of living standards, people have increasingly strict requirements for food safety and quality. Lamb, abundant in the Ningxia Hui Autonomous Region, is considered a top-quality product due to its tender texture, mild gamey smell, and rich nutrition. To ensure better taste, lamb undergoes a cooling and aging process after slaughter to remove excess acidic substances, further enhancing its tenderness and flavor while preserving its nutritional value. Currently, most lamb aging processes involve placing all lamb pieces in the same environment after slaughter. However, due to individual differences in breed, size, fat content, and sex, a uniform aging environment cannot address these individual variations, resulting in suboptimal quality and taste after aging. Summary of the Invention

[0003] In view of this, it is necessary to provide a lamb acid removal regulation system and method that can control the acid removal based on individual differences in lamb.

[0004] The present invention provides a mutton aging control system, comprising: an aging chamber, a mutton carcass conveying and suspension device, an environmental parameter adjustment device, a data acquisition and monitoring device, an RFID tag, a first RFID scanner, a second RFID scanner, and a control device.

[0005] The acid removal chamber is enclosed by four walls, including: an inlet and outlet located on the shorter wall; several independent acid removal compartments evenly distributed against the two walls perpendicular to the inlet and outlet walls; adjacent acid removal compartments do not share walls; a sliding door is installed on the wall of each acid removal compartment closest to the center line of the chamber; several indicator lights and alarm devices are installed near the sliding door of each acid removal compartment; the floor of the acid removal chamber slopes downwards from the center line perpendicular to the inlet and outlet walls; and a grid-like grid is installed on the floor of the acid removal chamber; the height of each part of the grid is proportional to the height of the inlet and outlet walls. The contact surfaces of the acid discharge chamber floor are matched, and the upper surface of the grid plate is horizontal. Two drip collection tanks are excavated on the outer side of the two side walls of the acid discharge chamber, away from the inlet and outlet. Two drip collection troughs are excavated on the lower inner side of the two side walls of the acid discharge chamber, with one end penetrating the wall of the acid discharge chamber and extending into the drip collection tank. A first intelligent control valve is installed at each position where the drip collection trough penetrates the wall of the acid discharge chamber to control the opening and closing of the drip collection trough. A baffle is installed between the acid discharge chamber floor and the drip collection trough, and a drip guide port is opened on the baffle. A certain gap is left between the baffle and the adjacent grid plate to allow the drip to pass through and flow to the drip guide port.

[0006] A mutton carcass conveying and hanging device is installed in the aging chamber to convey mutton carcasses that need to be aged and evenly hang them in the aging chamber.

[0007] An environmental parameter adjustment device is installed inside and outside each acid removal chamber. It is used to receive and execute commands from the control device to adjust the environmental parameters of the acid removal chamber.

[0008] The data acquisition and monitoring device is used to monitor in real time the pH value of the mutton carcass in each aging chamber, the pH value of the dripping liquid in each aging chamber, and the environmental parameters in each aging chamber. It includes: several meat pH meters, which are respectively installed in the corresponding aging chamber near the mutton carcass; and several industrial-grade pH sensors, which are respectively installed at the dripping inlet of each aging chamber.

[0009] RFID tags are attached to mutton carcasses to store basic carcass information, carcass classification information, and carcass aging information. A first RFID scanner is located outside the aging chamber's inlet and outlet. When a mutton carcass requiring aging enters the chamber, it scans the RFID tags on the carcass, reads the basic carcass information, and transmits it to the control device. The control device then writes the carcass classification information back into the corresponding RFID tag. When the mutton carcass leaves the aging chamber after aging is complete, the first RFID scanner writes the corresponding aging information into the RFID tag. A second RFID scanner is fixedly installed at the end of the suspension device near the inside of the aging chamber's inlet and outlet. After a mutton carcass requiring aging enters the chamber, the second RFID scanner scans the RFID tags on the carcass. The control device, based on the carcass classification information in the RFID tags, controls the indicator light of the aging chamber the carcass needs to enter to turn on, guiding the operators as they move the mutton carcass.

[0010] The control device includes: an industrial control computer, a human-machine interface module, and a display screen; the industrial control computer is electrically connected to both the human-machine interface module and the display screen; the industrial control computer is equipped with a carcass classification model and a mutton aging environment control model; when a mutton carcass requiring aging enters the aging chamber, the first RFID scanner scans the RFID tag on the mutton carcass, reads the basic carcass information, and transmits it to the control device; the carcass classification model classifies the mutton carcass according to the basic carcass information, generates carcass classification information, and writes the carcass classification information into the RFID tag; simultaneously, the mutton aging environment control model... Based on the carcass classification information, the system predicts the required aging environment parameters and optimal aging time for mutton carcasses of that category, and adjusts the environment of the corresponding aging chamber according to the predicted aging environment parameters and optimal aging time. When the mutton carcass completes aging and leaves the aging chamber, the control device controls the first RFID scanner to write the carcass aging information into the corresponding RFID tag. The first intelligent control valve, sliding door, indicator lights, alarm device, environmental parameter adjustment device, data acquisition and monitoring device, first RFID scanner, and second RFID scanner are all connected to the industrial control computer.

[0011] Preferably, the mutton carcass conveying and hanging device includes: several support frames, the upper part of which is fixedly connected to the ceiling of the aging chamber, and the lower part extending vertically downward to a certain distance from the floor of the aging chamber; a main hanging frame, set on the passageway of the aging chamber, in the shape of a U-shaped track, with its upper surface fixedly connected to the support frames and its lower track surface facing the floor of the aging chamber; several hanging sub-frames, one end of which is connected to the main hanging frame, and the other end of which passes through the wall of the corresponding aging chamber and extends into the aging chamber; each hanging sub-frame is in the shape of a U-shaped track, with its upper surface fixedly connected to the support frame and its lower track surface facing the floor of the aging chamber; and several hooks, with rollers at the top, which are movably connected to the main hanging frame and the hanging sub-frames through the rollers, and bidirectional hooks at the bottom for hanging mutton carcasses.

[0012] Preferably, the environmental parameter adjustment device includes: two meat aging and humidifying machines, humidifying pipes, and a number of refrigeration units, air heaters, fans, and second intelligent control valves, all connected to an industrial control computer; the two meat aging and humidifying machines are located on both sides of the inlet and outlet of the aging chamber, outside the aging chamber, and are used to adjust the humidity of the aging chambers on both sides of the passageway; one end of the humidifying pipe is connected to the outlet of the meat humidifier, and the other end extends into several branches that penetrate the walls of the corresponding aging chambers and extend into each aging chamber; several humidification holes are evenly opened on the humidifying pipes extending into each aging chamber; a second intelligent control valve is installed at the connection between the humidifying pipe and the aging chamber wall to adjust the total amount of moisture entering each aging chamber; the refrigeration units and fans are fixedly installed on the outer walls of the corresponding aging chambers, with the cold air outlets of the refrigeration units and the air vents of the fans facing into the aging chambers; and several air heaters are installed in the corresponding aging chambers.

[0013] Preferably, the data acquisition and monitoring device further includes: several wind speed probes, several humidity probes, and several temperature sensors; the wind speed probes are respectively installed at the air outlets of the fans in each aging chamber; the humidity probes are respectively installed in each aging chamber at a location away from the meat aging humidifier and refrigeration unit; the temperature sensors are respectively installed in each aging chamber; the wind speed probes, humidity probes, and temperature sensors are all connected to the industrial control computer for communication.

[0014] Preferably, the entrance and exit of the acid removal chamber are double doors, including: an inner door, an outer door, and a transition chamber connecting the inner door and the outer door; a first RFID scanner is located on the upper outer side of the outer door; and a control device is located on one side of the outer door.

[0015] Preferably, the basic information of the carcass is stored in RFID tags during the slaughter stage, including: breed, body type, weight, fatness, sex and slaughter time of the live sheep at the time of sorting; body type includes: body length, body width and body height;

[0016] The carcass classification information is written into the RFID tag by the first RFID scanner when the carcass enters the aging room before aging. This includes: the classification result of the carcass after classification, and the aging silo number that the carcass needs to enter for aging. During classification, breed is the primary classification basis, and the weight and body size of sheep of the same breed are the secondary classification basis.

[0017] The carcass aging information is written into the RFID tag by the first RFID scanner when the carcass leaves the aging room after aging is completed. This includes: the aging environment parameters and optimal aging time used during the aging process, as well as the pH value of the mutton carcass and the pH value of the dripping liquid after aging is completed; the aging environment parameters include: temperature, humidity and wind speed during the aging process.

[0018] Preferably, the carcass classification model and the mutton aging environment control model configured in the industrial control computer are obtained through training based on the accumulated aging data in the early stage;

[0019] The process of obtaining the carcass classification model is as follows:

[0020] Step 1: Data Accumulation

[0021] Before each mutton carcass enters the aging chamber, the RFID tags of the mutton carcass are scanned by the first RFID scanner, and the basic information of the carcass is entered into the industrial control computer. The mutton carcasses are then manually classified according to the basic information of the carcasses. First, they are classified by breed, and then sheep of the same breed are classified by weight and body shape. The manually classified carcass information is stored in the industrial control computer.

[0022] Step 2, Data Preprocessing:

[0023] After accumulating basic carcass information and manually classified carcass information for a period of time, Python software is used to preprocess the accumulated data, including reading, cleaning, and feature selection.

[0024] Step 3: Model Generation

[0025] Based on the order of breed as the primary classification criterion, and weight and body size of sheep of the same breed as the secondary classification criterion, gradient boosting tree or random forest is selected as the classification model. Based on the above accumulated data, the model is trained using the scikit-learn library in Python software to generate a carcass classification model.

[0026] Step 4: Model Optimization

[0027] The above carcass classification model was deployed to an industrial computer. During subsequent optimization and training, the industrial computer used the carcass classification model to classify mutton carcasses. After the classification results were given, they were manually verified to check the classification results of the industrial computer and make improvements. Through iterative optimization and training of the carcass classification model over a certain period of time, a carcass classification model that can accurately classify mutton carcasses according to the priority order of classification criteria was obtained.

[0028] The process of obtaining the aging environment regulation model for mutton is as follows:

[0029] Step 1: Data Accumulation

[0030] Before each aging process begins, the operator manually predicts the aging information of the carcass based on experience, namely the aging environment parameters and optimal aging time corresponding to each aging chamber in the aging room. During the aging process, the industrial control computer adjusts the environmental parameters according to the manual prediction and stops aging when the optimal aging time is reached. After aging is completed, the operator manually saves the carcass classification information in correspondence with the predicted values ​​of the aging environment parameters and the optimal aging time for each aging chamber. After aging is completed, the operator judges the quality of the predicted values ​​of the aging environment and the optimal aging time based on the condition of the mutton carcass after aging. If the aging condition is good, the carcass aging information corresponding to the aging chamber is placed in the folder of usable data; if the aging condition is poor, it is placed in the folder of unusable data.

[0031] Step 2, Data Preprocessing:

[0032] Once the carcass acid removal information in the aforementioned usable data folder has accumulated for a year or reached more than 500 records, Python software is used to preprocess the accumulated data, including reading, cleaning, and feature selection.

[0033] Step 3: Model Generation

[0034] Based on the accumulated preprocessed data mentioned above, a regression model was selected as the classification model, and the scikit-learn library in Python was used to train the model to generate a mutton aging environment regulation model.

[0035] Step 3: Model Optimization

[0036] The aforementioned mutton aging environment control model was deployed to an industrial control computer. During subsequent optimization training, before aging began, the industrial control computer used the mutton aging environment control model to predict the aging information of the carcasses in each aging chamber, namely the aging environment parameters and the optimal aging time. During aging, the industrial control computer adjusted the environmental parameters according to the predicted aging environment parameters and stopped aging when the predicted optimal aging time was reached. After aging was completed, manual verification was performed to check the prediction results of the industrial control computer and make improvements. Through iterative optimization training of the mutton aging environment control model over a certain period of time, a mutton aging environment control model that can accurately predict the aging environment parameters and the optimal aging time was obtained.

[0037] The present invention provides a method for regulating the aging of mutton, which uses the above-mentioned mutton aging regulation system and includes the following steps:

[0038] S0. Prepare the mutton carcass that needs to be deacidified. The mutton carcass is the mutton carcass with an RFID tag after slaughter. The RFID tag stores the basic information of the mutton carcass.

[0039] S1. Start the control device, confirm that the environmental parameter adjustment device and data acquisition and monitoring device are in good working order, confirm that the sliding doors of each acid discharge chamber are in the open position, and all first intelligent control valves are in the closed position.

[0040] S2. Workers push the prepared mutton carcasses through the double-door outer door into the transition room using a trolley. The first RFID scanner scans the RFID tags on the mutton carcasses and transmits the acquired basic carcass information to the industrial control computer. The carcass classification model classifies the mutton carcasses and generates carcass classification information. The first RFID scanner writes the carcass classification information into the corresponding RFID tags. At the same time, the mutton aging environment control model predicts the aging information required for this type of mutton carcass based on the carcass classification information.

[0041] S3. The operator pushes the mutton carcass from the transition room into the inner door and hangs it on the hook. The second RFID scanner scans the RFID tag of the mutton carcass and transmits the data to the industrial control computer. The industrial control computer opens the indicator light and sliding door of the corresponding aging chamber according to the obtained carcass classification information. The operator pushes the mutton carcass into the corresponding aging chamber according to the indicator light.

[0042] S4. After all the mutton carcasses have been placed, the operators exit the aging chamber and report the completion of placement to the industrial control computer via the human-machine interface module; the industrial control computer then closes the sliding doors and indicator lights of all aging chambers.

[0043] S5. The industrial control computer starts the acid removal process; based on the predicted carcass acid removal information for each acid removal chamber and in conjunction with the feedback from the data acquisition and monitoring device, the industrial control computer begins to control the environmental parameter adjustment device to adjust the environment of each acid removal chamber accordingly.

[0044] S6. During the aging process, the data acquisition and monitoring device monitors the environmental parameters, the pH value of the mutton carcass, and the pH value of the dripping liquid in each aging chamber in real time, and feeds them back to the industrial control computer. The industrial control computer compares the received data with the aging information of the carcass predicted by the mutton aging environment control model. If there is a deviation, the industrial control computer generates an adjustment command in time and sends it to the corresponding environmental parameter adjustment device for adjustment. At the same time, the industrial control computer sends the aging status of each aging chamber to the display screen for display, so that the operators can check it at any time.

[0045] S7. When the aging process in a certain aging chamber is complete, the industrial control computer notifies the alarm device of the corresponding aging chamber to activate. The operator enters the aging chamber and, according to the alarm device's prompts, retrieves the mutton carcass from the corresponding aging chamber. As the mutton carcass leaves the aging chamber, the first RFID scanner writes the corresponding aging information into the RFID tag, and the status of the aging chamber on the display screen shows "completed". The operator then sends the aging-completed mutton carcass into the cold storage for preservation.

[0046] S8. After all the mutton carcasses have been de-acidified and removed, the industrial control computer opens the first intelligent control valve to connect the drip collection tanks in each de-acidification chamber, so that the blood water generated during the de-acidification process flows into the drip collection tank. The operator then shuts off the mutton de-acidification control system, and the de-acidification process ends.

[0047] Preferably, in step S6, the industrial control computer generates adjustment instructions in a timely manner and sends them to the corresponding environmental parameter adjustment device for adjustment. Specifically, the industrial control computer controls the fan to adjust the wind speed based on the feedback of air flow from the wind speed probe; the industrial control computer controls the opening of the second intelligent control valve at the connection between the humidification pipe and the acid discharge chamber wall based on the feedback of humidity from the humidity probe to adjust the total amount of moisture entering the acid discharge chamber; and the industrial control computer controls the refrigeration unit or air heater to adjust the temperature based on the temperature feedback from the temperature sensor.

[0048] Preferably, in step S2, the carcass classification model classifies mutton carcasses and generates carcass classification information. Specifically, the carcass classification model first performs primary classification based on breed, and then performs secondary classification based on weight and body shape for sheep of the same breed.

[0049] The aforementioned mutton aging control system and method achieves aging control tailored to individual mutton differences through the following setup: First, independent aging chambers are set up within the aging room, with environments remaining independent and unaffected by each other, providing more precise aging space for different types of mutton. Second, RFID tags are attached to the mutton carcasses, and a first and second RFID scanner are installed at appropriate locations within the aging room. A carcass classification model and a mutton aging environment control model are configured in the control device. Through their coordination, the mutton carcasses undergoing aging are classified according to classification criteria, ensuring that mutton carcasses of the same type enter the same aging chamber, while mutton carcasses of different types enter different aging chambers. Third, by placing environmental parameter adjustment devices and data acquisition and monitoring devices inside or outside each aging chamber, the aging environment parameters of each chamber can be monitored and adjusted in real time, ensuring independent operation between each aging chamber, thereby achieving independent classification and control of mutton carcasses. Fourth, by installing a first intelligent control valve at the location where the drip collection tank penetrates the wall of the aging chamber, the aging chamber remains closed during the aging of the mutton carcass, ensuring the independent environment of each aging chamber. After aging is completed, the first intelligent control valve opens, allowing the drips generated during aging to drain from the aging chamber into the drip collection tank, preparing for the next aging process and ensuring that the environment for the new aging is not affected by the previous aging environment. Fifth, by installing a grid on the floor of the aging chamber, the number of workers entering and exiting the aging chamber is reduced. The invention addresses the contamination of blood dripping from mutton carcasses during storage, making the industrial-grade pH sensor's measurements more accurate. Furthermore, by setting baffles and drip diversion ports, and positioning the industrial-grade pH sensor at the drip diversion port to measure the flowing blood droplets, the invention further enhances the accuracy of the industrial-grade pH sensor's measurements. Therefore, compared to existing technologies that place all mutton carcasses in a uniform aging environment, this invention enables personalized aging of different mutton individuals, improving the quality and taste of the mutton.

[0053] The technical solutions and effects of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0054] Please refer to Figure 1 As shown, the mutton aging control system provided by the present invention includes: an aging chamber 1, a mutton carcass conveying and hanging device, an environmental parameter adjustment device, a data acquisition and monitoring device, an RFID tag, a first RFID scanner 6, a second RFID scanner 7, and a control device.

[0055] The acid removal chamber 1 is enclosed by four walls, including: an inlet and outlet, located on the shorter wall; four independent acid removal chambers 11, evenly arranged against the two walls perpendicular to the walls of the inlet and outlet within the acid removal chamber 1; adjacent acid removal chambers 11 do not share walls; a sliding door 110 is installed on the wall of the acid removal chamber 11 closest to the center line of the acid removal chamber 1; four indicator lights 12 and four alarm devices 13 are respectively located near the sliding door of each acid removal chamber; the floor of the acid removal chamber 1 slopes downwards from the center line perpendicular to the walls of the inlet and outlet; a grid-like grid of grates is installed on the floor of the acid removal chamber 1; the height of each part of the grid 14 is the same as the height of the acid removal chamber 1 it contacts. The ground surface is matched, and the upper surface of the grid plate 14 is horizontal. Two drip collection tanks 15 are respectively excavated on the outer side of the two side walls of the acid discharge chamber 1, away from the inlet and outlet. Two drip collection troughs 16 are respectively excavated on the lower inner side of the two side walls of the acid discharge chamber 1, with one end penetrating through the wall of the acid discharge chamber 1 and extending into the drip collection tank 15. A first intelligent control valve 17 is installed at the position where the drip collection trough 16 penetrates the wall of the acid discharge chamber 11 to control the opening and closing of the drip collection trough 16. A baffle 18 is set between the ground of the acid discharge chamber 11 and the drip collection trough 16, and a drip guide port 19 is opened on the baffle 18. A certain gap is left between the baffle 18 and the adjacent grid plate 14 so that the drip can pass through and flow to the drip guide port 19.

[0056] A mutton carcass conveying and hanging device is installed in the aging chamber 1 to convey mutton carcasses that need to be aged and evenly hang them in the aging chamber 11.

[0057] An environmental parameter adjustment device is installed inside and outside each acid removal chamber 11 to receive and execute commands from the control device to adjust the environmental parameters of the acid removal chamber 11.

[0058] The data acquisition and monitoring device is used to monitor in real time the pH value of the mutton carcass in each aging chamber 11, the pH value of the dripping liquid in each aging chamber, and the environmental parameters in each aging chamber. It includes: four meat pH meters, which are respectively installed in the corresponding aging chamber near the mutton carcass; and four industrial-grade pH sensors 40, which are respectively installed at the dripping inlet 19 of each aging chamber 11.

[0059] RFID tags, attached to the mutton carcass, are used to store basic carcass information, carcass classification information, and carcass aging information. A first RFID scanner 6, located outside the entrance and exit of the aging chamber 1, scans the RFID tags on the mutton carcass when it enters the aging chamber 1, reads the basic carcass information and transmits it to the control device, then writes the carcass classification information returned by the control device into the corresponding RFID tag. When the mutton carcass leaves the aging chamber after aging is complete, the first RFID scanner... The RFID scanner 6 writes the corresponding carcass aging information into the RFID tag; the second RFID scanner 7 is fixedly installed at one end of the suspension device near the inside of the aging chamber 1. After the mutton carcass that needs to be aged enters the aging chamber, the second RFID scanner 7 scans the RFID tag on the mutton carcass. The control device controls the indicator light 12 of the aging chamber 11 that the mutton carcass needs to enter to open according to the carcass classification information in the RFID tag, so as to guide the operators to transfer the mutton carcass.

[0060] The control device includes an industrial computer 50, a human-machine interface module 52, and a display screen 51. The industrial computer 50 is electrically connected to the human-machine interface module 52 and the display screen 51. The industrial computer 50 is equipped with a carcass classification model and a mutton aging environment control model. When a mutton carcass requiring aging enters the aging chamber, the first RFID scanner 6 scans the RFID tag on the mutton carcass, reads the basic carcass information, and transmits it to the control device. The carcass classification model classifies the mutton carcass according to the basic carcass information, generates carcass classification information, and writes the carcass classification information into the RFID tag. Simultaneously, the mutton aging environment control model... Based on the carcass classification information, the required aging environment parameters and optimal aging time for this type of mutton carcass are predicted, and the environment of the corresponding aging chamber 11 is adjusted according to the predicted aging environment parameters and optimal aging time. When the mutton carcass leaves the aging chamber 1 after aging is completed, the control device controls the first RFID scanner 6 to write the carcass aging information into the corresponding RFID tag. The first intelligent control valve 17, sliding door 110, indicator light 12, alarm device 13, environmental parameter adjustment device, data acquisition and monitoring device, first RFID scanner 6, and second RFID scanner 7 are all connected to the industrial control computer.

[0061] In this embodiment, both the sliding door 110 and the inlet / outlet door panels of the acid removal chamber 1 are made of thermal insulation material; the internal walls and ceiling of the acid removal chamber 1 are inlaid with thermal insulation panels to maintain stable temperature and humidity requirements within the acid removal chamber 1, and are coated with waterproof material to prevent the internal walls of the acid removal chamber 1 from becoming damp and moldy; thermal insulation strips are installed at the contact points between the sliding door 110 and the walls of the acid removal chamber 11 to ensure a more stable internal environment within the acid removal chamber 11; the sliding door 110 is connected to the industrial control computer 50 for communication. The opening and closing of the sliding door 110 is controlled by the industrial control computer 50. Before the acid removal begins, the industrial control computer 50 controls all the sliding doors 110 of the acid removal chambers 11 to be in the open state. After the operators send all the mutton carcasses into the corresponding acid removal chambers 11, the industrial control computer 50 controls all the sliding doors 110 of the acid removal chambers 11 to be closed. When the acid removal of a certain acid removal chamber 11 is completed, the industrial control computer 50 controls the alarm bell of the corresponding alarm device 13 to sound, and at the same time controls the corresponding sliding door 110 to be opened.

[0062] In this embodiment, the alarm device 13 includes an alarm bell and a flashing light. By communicating with the industrial control computer 50, after the acid removal of a certain acid removal chamber 11 is completed, the industrial control computer 50 controls the alarm device 13 to operate. The alarm bell sounds and the flashing light flashes, notifying the workers that the acid removal is complete, prompting the workers to take out the mutton carcass that has completed the acid removal as soon as possible. Even if the workers are not watching in front of the display screen, they can hear the prompt based on the sound of the alarm bell and can carry out the work in a timely manner.

[0063] In this embodiment, by setting up a grid plate 14, the floor of the acid removal chamber 1 is separated from the surface that is manually stepped on. On the one hand, this avoids the influence of the pH of the blood on the workers' contact with the ground during the operation, which could lead to inaccurate measurements. On the other hand, it prevents the presence of dripping liquid from causing workers to slip and fall, thus avoiding safety accidents. The bottom of the wall of each acid removal chamber 11 is tightly connected to the ground inside the acid removal chamber 1. The grid plate 14 is rearranged across the wall of the acid removal chamber 11 to avoid disrupting the independent acid removal environment of the acid removal chamber 11. By setting the floor of the acid removal chamber 1 as a slope, the blood dripping liquid can more easily flow towards the dripping guide port 19 and enter the dripping collection tank 16. The dripping collection tank 16 is a strip-shaped groove dug in the floor of the acid removal chamber, and the dripping collection box 15 is a groove dug in the floor outside the acid removal chamber 1.

[0064] In this embodiment, the first intelligent control valve 17 is used to control the opening and closing of the drip collection tank 16. When the mutton carcass begins to be de-acidified, the industrial control computer 50 controls the first intelligent control valve 17 to close, and the drip collection tank 16 is in a "blocked" state. The drips in each de-acidification chamber 11 are independently isolated in their respective de-acidification chambers, without interfering with each other. This protects the independence of the de-acidification environment of each de-acidification chamber 11 and prevents them from affecting each other. When all the mutton carcasses have been de-acidified and removed, the industrial control computer 50 controls the first intelligent control valve 17 to open, and the drip collection tank 16 is in a "open" state. The drip collection tanks 16 in each de-acidification chamber 11 are connected, and the drips discharged from each de-acidification chamber 11 into the drip collection tank 16 can flow into the drip collection box 15 to prepare for the next de-acidification environment.

[0065] In this embodiment, the meat pH meter is positioned near the mutton carcass via a rotating bracket (not shown in the figure), which is located inside the sliding door 110. During measurement, the rotating bracket is rotated to bring the meat pH meter close to the mutton carcass for testing. When the measurement is finished, the rotating bracket is rotated to remove the meat pH meter from the mutton carcass. The industrial-grade pH sensor 40 is used to detect the pH value of blood and other droplets falling from the mutton carcass during the aging process. The industrial-grade pH sensor 40 has sufficient durability and protection to withstand long-term placement in droplets. When the aging process is not being performed, the industrial-grade pH sensor 40 should be cleaned and maintained.

[0066] In this embodiment, the human-computer interaction module 52 is used for operators to operate the industrial control computer 50. In particular, for the carcass classification model and mutton aging environment control model configured in the industrial control computer 50, during the early data accumulation and training stages, the data accumulation, preprocessing, model generation and model optimization processes all require manual operation on the industrial control computer 50 through the human-computer interaction module 52.

[0067] In this embodiment, the display screen 51 is used to display general information and the status of each aging chamber, such as time; the display screen 51 shows the corresponding position of each aging chamber 11 and the status of each aging chamber 11 during the aging process, specifically: when preparing for aging, if the environmental parameter adjustment device and data acquisition and monitoring device are confirmed to be in good working order, each aging chamber 11 will be displayed in gray, indicating that each aging chamber 11 is ready; after the mutton carcass is sorted and enters the corresponding aging chamber, the industrial control computer will open all sliding doors. When 110 is closed, each aging chamber 11 on display screen 51 is displayed in red, indicating that aging is in progress; when aging in a certain aging chamber 11 is completed, each aging chamber 11 on display screen 51 is displayed in green, indicating that aging is complete; when all the aging-completed mutton carcasses in a certain aging chamber 11 are removed and scanned by the first RFID scanner 6 outside the double door 10, the corresponding aging chamber 11 is displayed in gray again; during aging, the operator can identify the status of the aging chamber 11 according to the color status of the aging chamber 11 on display screen 51.

[0068] Further, see Figure 1 As shown, to facilitate the transfer of mutton carcasses from the aging chamber 1 to each aging bin 11 and to ensure that the mutton carcasses are evenly placed within the aging bin 11, the mutton carcass transfer suspension device includes: several support frames 20, the upper part of which is fixedly connected to the ceiling of the aging chamber 1, and the lower part extending vertically downward to a certain distance from the ground of the aging chamber 1; a main suspension frame 21, set on the passageway of the aging chamber 1, in the shape of a U-shaped track, the upper plane of which is fixedly connected to the support frames 20, and the lower track surface facing the ground of the aging chamber 1; and four separate suspension frames 22, one end of which is connected to the main suspension frame. 21 is connected, and the other end passes through the wall of the corresponding aging chamber 11 and extends into the aging chamber 11; each hanging bracket 22 is in the shape of a U-shaped track, with the upper surface fixedly connected to the support frame 20 and the lower track surface facing the ground of the aging chamber 1; several hooks 23 are provided with rollers on the upper part, which are movably connected to the main hanging frame 21 and the hanging brackets 22 through the rollers, and bidirectional hooks are provided on the lower part for hanging mutton carcasses; in this embodiment, the lower part of the support frame 20 extends vertically downward to a certain distance from the ground of the aging chamber 1, which can prevent the mutton carcass from contacting the ground.

[0069] Furthermore, to provide a more precise environment for different types of lamb carcasses, see [link to relevant documentation]. Figure 1As shown, the environmental parameter adjustment device includes: two meat aging and humidifying machines 30, humidifying pipes 31, and four refrigeration units 32, four air heaters 33, four fans 34, and four second intelligent control valves 32, all of which are communicatively connected to the industrial control computer 50. The two meat aging and humidifying machines 30 are respectively located on both sides of the inlet and outlet of the aging chamber 1, outside the aging chamber 11, and are used to adjust the humidity of the aging chambers 11 on both sides of the passage of the aging chamber 1. One end of the humidifying pipe 31 is connected to the outlet of the meat aging and humidifying machine 30, and the other end extends into four branches, which pass through the walls of the corresponding aging chambers 11 and extend into each aging chamber 11. Several humidification holes 310 are evenly opened on the humidifying pipes 31 extending into each aging chamber 11. A set of ventilation holes 310 is provided at the connection between the humidifying pipe 31 and the wall of the aging chamber 11. The second intelligent control valve 32 is used to regulate the total amount of moisture entering each aging chamber 11; four refrigeration units 32 are fixedly installed on the outer wall of the corresponding aging chamber 11, with their horizontal position higher than the hanging bracket 22. The cold air outlet of the refrigeration unit 32 faces into the aging chamber 11 and does not face the carcass to avoid uneven cold air diffusion, which would affect the aging effect of the carcass; four fans 34 are fixedly installed on the outer wall of the corresponding aging chamber 11, with the horizontal position of the fan 34 air outlet higher than the carcass hanging bracket to avoid the problems of accelerated skin drying and poor aging effect caused by the air outlet facing the mutton carcass. In addition, the fan 34 also includes a check valve installed in the fan duct (not shown in the figure) to prevent sand and insects and other reptiles from entering the aging chamber; four air heaters 33 are respectively installed in the corresponding aging chamber 11. In this embodiment, by setting up a meat aging and humidification machine 30 and a humidification vent 310, the aging environment of the mutton carcass can be humidified during the aging process, preventing the skin of the mutton carcass from drying out and losing moisture due to prolonged exposure to dry air. Simultaneously, a certain level of humidity can inhibit the growth of microorganisms and help the volatilization and discharge of acidic substances produced during the aging process, thus promoting the aging effect. By setting up a second intelligent control valve 32, and controlling the opening degree of each second intelligent control valve 32 separately through an industrial control computer 50, when… When the humidity in a certain aging chamber 11 is low and needs to be increased, the industrial control computer 50 controls the corresponding second intelligent control valve 32 to increase its opening. When the humidity in a certain aging chamber 11 is high and needs to be decreased, the industrial control computer 50 controls the corresponding second intelligent control valve 32 to decrease its opening, thereby controlling the humidity of each aging chamber 11. By evenly opening dehumidification holes 310 on the humidification pipes 31 extending into each aging chamber 11, the humidity regulation in each aging chamber 11 is more uniform in space, and the moisturizing effect on the surface of the mutton carcass is also more uniform.

[0070] In this embodiment, the air heater 33 is installed on the hanging bracket 22 inside the acid removal chamber 11 to heat the acid removal chamber 11 under extreme weather conditions, so as to prevent the temperature from being too low and affecting the acid removal effect and prolonging the acid removal time.

[0071] In this embodiment, the refrigeration unit 32 is used to maintain the low temperature conditions in the acid removal chamber 11 in order to inhibit the growth of microorganisms, slow down the activity of enzymes, inhibit the spoilage of meat and retain its nutrition and taste.

[0072] In this embodiment, the fan 34 is installed next to the refrigeration unit 32 in each of the aging chambers 11. On the one hand, it provides a certain wind speed to accelerate the heat exchange process between the air and the surface of the mutton, effectively shortening the aging time. On the other hand, it can also ensure uniform air circulation and reduce the accumulation of harmful gases and substances in the aging chamber.

[0073] Furthermore, to more accurately control the aging environment, the data acquisition and monitoring device also includes: four wind speed probes (not shown in the figure), four humidity probes (not shown in the figure), and four temperature sensors (not shown in the figure); the wind speed probes are respectively installed at the air outlets of the fans 34 in each aging chamber 11; the humidity probes are respectively installed in each aging chamber 11 at a position away from the meat aging humidifier 30 and the refrigeration unit 32; the temperature sensors are respectively installed in each aging chamber 11; the wind speed probes, humidity probes, and temperature sensors are all communicatively connected to the industrial control computer 50;

[0074] In this embodiment, the wind speed probe is placed at the air outlet of the fan 34 in each deacidification chamber 11, and it must be ensured that the wind speed probe is not blocked by any object in order to accurately monitor the airflow in the deacidification chamber 11; the humidity probe should be installed at a certain height above the ground to ensure that the average humidity of the entire deacidification chamber 11 is monitored, and the sensing surface of the humidity probe should face the direction of airflow to obtain more accurate humidity data. In addition, the humidity probe should have waterproof and dustproof protection measures, and should be kept away from equipment that may cause humidity fluctuations, such as the meat deacidification humidifier 30 and the refrigeration unit 32; the temperature sensor is installed at a certain height inside the deacidification chamber 11 with the sensing surface facing the airflow to avoid direct influence from heat or cold sources and reduce errors caused by local heat convection;

[0075] In this embodiment, by connecting the wind speed probe, humidity probe, and temperature sensor to the industrial control computer 50, the data measured by each of them can be fed back to the industrial control computer 50 in real time.

[0076] Further, see Figure 2 As shown, the entrance and exit of the acid removal chamber 1 are double doors 10, including: an inner door (not shown in the figure), an outer door 100, and a transition chamber 101 connecting the inner door and the outer door 100; the first RFID scanner 6 is located above the outer side of the outer door 100; the control device is located on one side of the outer side of the outer door 100.

[0077] In this embodiment, by setting up double doors 10, the impact of operators entering and exiting the acid removal chamber 1 on the temperature, humidity and other environmental conditions of the acid removal chamber 1 is minimized.

[0078] Furthermore, basic carcass information is stored in RFID tags during the slaughter stage, including: breed, body type, weight, fatness, sex, and slaughter time of the live sheep at the time of sorting; body type includes: body length, body width, and body height;

[0079] The carcass classification information is written into the RFID tag by the first RFID scanner 6 when the carcass enters the aging chamber 1 before aging. This includes: the classification result of the carcass after classification, and the aging chamber number that the carcass needs to enter for aging. During classification, breed is the primary classification basis, and the weight and body size of sheep of the same breed are the secondary classification basis.

[0080] Carcass aging information: When the aging process is completed and the carcass leaves the aging chamber 1, the information is written into the RFID tag by the first RFID scanner 6. This includes: the aging environment parameters and the optimal aging time used during the aging process of the carcass, as well as the pH value of the mutton carcass and the pH value of the dripping liquid after the aging process is completed; the aging environment parameters include: temperature, humidity and wind speed during the aging process.

[0081] Furthermore, the carcass classification model and the mutton aging environment control model configured in the industrial control computer 50 are obtained through training based on the accumulated aging data from the previous period.

[0082] The process of obtaining the carcass classification model is as follows:

[0083] Step 1: Data Accumulation

[0084] Before each mutton carcass enters the aging chamber 1, the RFID tag of the mutton carcass is scanned by the first RFID scanner 6, and the basic information of the carcass is entered into the industrial control computer. The mutton carcasses are classified manually according to the basic information of the carcasses. First, they are classified by breed, and then sheep of the same breed are classified by weight and body shape. The manually classified carcass information is stored in the industrial control computer.

[0085] Step 2, Data Preprocessing:

[0086] After a period of time, the accumulated data of basic carcass information and manually classified carcass information are preprocessed using Python software, including reading, cleaning, and feature selection.

[0087] Step 3: Model Generation

[0088] Based on the order of breed as the primary classification criterion, and weight and body size of sheep of the same breed as the secondary classification criterion, gradient boosting tree or random forest is selected as the classification model. Based on the above accumulated data, the model is trained using the scikit-learn library in Python software to generate a carcass classification model.

[0089] Step 4: Model Optimization

[0090] The above carcass classification model is deployed to the industrial computer 50. During the subsequent optimization and training process, the industrial computer 50 uses the carcass classification model to classify mutton carcasses. After the classification results are given, they are manually verified to check the classification results of the industrial computer and make improvements. Through iterative optimization and training of the carcass classification model over a certain period of time, a carcass classification model that can accurately classify mutton carcasses according to the priority order of classification criteria is obtained.

[0091] The process of obtaining the aging environment regulation model for mutton is as follows:

[0092] Step 1: Data Accumulation

[0093] Before each aging process begins, the operator manually predicts the aging information of the carcass based on experience, namely the aging environment parameters and optimal aging time corresponding to each aging chamber 11 in the aging chamber 1. During the aging process, the industrial control computer 50 adjusts the environmental parameters according to the manually predicted aging environment parameters and stops aging when the manually predicted optimal aging time is reached. After aging is completed, the operator manually saves the carcass classification information in correspondence with the predicted values ​​of the aging environment parameters and the optimal aging time of each aging chamber. After aging is completed, the operator judges the quality of the predicted aging environment parameters and the optimal aging time based on the condition of the mutton carcass after aging. If the aging condition is good, the carcass aging information corresponding to the above-mentioned aging chamber is placed in the folder of usable data; if the aging condition is bad, it is placed in the folder of unusable data.

[0094] Step 2, Data Preprocessing:

[0095] Once the carcass acid removal information in the aforementioned usable data folder has accumulated for a year or reached more than 500 records, Python software is used to preprocess the accumulated data, including reading, cleaning, and feature selection.

[0096] Step 3: Model Generation

[0097] Based on the accumulated preprocessed data mentioned above, a regression model was selected as the classification model, and the scikit-learn library in Python was used to train the model to generate a mutton aging environment regulation model.

[0098] Step 4: Model Optimization

[0099] The above-mentioned mutton aging environment control model is deployed in the industrial control computer 50. During subsequent optimization training, before aging begins, the industrial control computer 50 uses the mutton aging environment control model to predict the aging information of each aging 11 carcass, namely the aging environment parameters and the optimal aging time. During aging, the industrial control computer 50 adjusts the environment parameters according to the predicted aging environment parameters and stops aging when the predicted optimal aging time is reached. After aging is completed, manual verification is performed to check the prediction results of the industrial control computer and make improvements. Through cyclical training of the mutton aging environment control model over a certain period of time, a mutton aging environment control model that can accurately predict the aging environment parameters and the optimal aging time is obtained.

[0100] In this embodiment, the operator performs the above operations on the industrial control computer 50 through the human-computer interaction module 52 during the data accumulation, data preprocessing, model generation and model optimization processes.

[0101] The method for regulating the aging of mutton provided by this invention, using the mutton aging regulation system provided by this invention, includes the following steps:

[0102] S0. Prepare the mutton carcass that needs to be deacidified. The mutton carcass is the mutton carcass with an RFID tag after slaughter. The RFID tag stores the basic information of the mutton carcass.

[0103] S1. Start the control device, confirm that the environmental parameter adjustment device and data acquisition and monitoring device are in good working condition, confirm that the sliding door 110 of each acid discharge chamber 11 is in the open state, and all first intelligent control valves 17 are in the closed state.

[0104] S2. Workers push the prepared mutton carcasses through the double-door outer door 100 into the transition room 101 using a trolley. The first RFID scanner 6 scans the RFID tags on the mutton carcasses and transmits the acquired basic carcass information to the industrial control computer 50. The carcass classification model classifies the mutton carcasses and generates carcass classification information. The first RFID scanner 6 writes the carcass classification information into the corresponding RFID tags. At the same time, the mutton aging environment control model predicts the aging information required for this type of mutton carcass based on the carcass classification information.

[0105] S3. The operator pushes the mutton carcass from the transition room 101 into the inner door and hangs it on the hook 23. The second RFID scanner 7 scans the RFID tag of the mutton carcass and transmits the data to the industrial control computer 50. The industrial control computer 50 turns on the indicator light 12 of the corresponding aging chamber 11 according to the obtained carcass classification information. The operator pushes the mutton carcass into the corresponding aging chamber 11 according to the guidance of the indicator light 12. After completion, the industrial control computer 50 turns off the indicator light 12 of the aging chamber 11.

[0106] S4. After all the mutton carcasses have been placed, the operator exits the aging chamber 1 and sends the information of completion to the industrial control computer 50 through the human-machine interaction module 52; the industrial control computer 50 closes the sliding doors 110 and indicator lights 12 of all aging chambers 11.

[0107] S5. The industrial control computer 50 starts the acid removal process: Based on the predicted carcass acid removal information of each acid removal chamber 11 and combined with the feedback from the data acquisition and monitoring device, the industrial control computer 50 starts to control the environmental parameter adjustment device to adjust the environment in each acid removal chamber 11 accordingly.

[0108] S6. During the aging process, the data acquisition and monitoring device monitors the environmental parameters, the pH value of the mutton carcass, and the pH value of the dripping liquid in each aging chamber 11 in real time, and feeds them back to the industrial control computer 50. The industrial control computer 50 compares the received data with the aging information of the carcass predicted by the mutton aging environment control model. If there is a deviation, the industrial control computer 50 generates an adjustment command in time and sends it to the corresponding environmental parameter adjustment device for adjustment. At the same time, the industrial control computer 50 sends the aging status of each aging chamber 11 to the display screen 51 for display, so that the operators can check it at any time.

[0109] S7. When the aging process in a certain aging chamber 11 is completed, the industrial control computer 50 notifies the alarm device 13 of the corresponding aging chamber 11 to operate. The operator enters the aging chamber 1 and, according to the prompt of the alarm device 13, enters the corresponding aging chamber 11 to take out the mutton carcass. When the mutton carcass leaves the aging chamber 1, the first RFID scanner 6 writes the corresponding aging information of the carcass into the RFID tag. At the same time, the status of the aging chamber on the display screen 51 is displayed as completed. The operator then sends the aging-completed mutton carcass into the cold storage for preservation.

[0110] S8. After all the mutton carcasses have been de-acidified and removed, the industrial control computer 50 opens the first intelligent control valve 17, connecting the drip collection tanks 16 in each de-acidification chamber 11, so that the blood water generated during the de-acidification process flows into the drip collection box 15. The operator then shuts off the mutton de-acidification control system, and the de-acidification process ends.

[0111] Further, in step S6, the industrial control computer 50 generates adjustment commands in a timely manner and sends them to the corresponding environmental parameter adjustment devices for adjustment. Specifically, the industrial control computer 50 controls the fan 34 to adjust the wind speed based on the feedback of air flow from the wind speed probe; the industrial control computer 50 controls the opening of the second intelligent control valve 32 at the connection between the humidification pipe 31 and the wall of the acid discharge chamber 11 based on the feedback of humidity from the humidity probe, thereby adjusting the total amount of moisture entering the acid discharge chamber 11; and the industrial control computer 50 controls the refrigeration unit 32 or the air heater 33 to adjust the temperature based on the temperature feedback from the temperature sensor.

[0112] In this embodiment, due to the need for deacidification and in order to achieve the best deacidification effect, the mutton carcass needs to be placed in sections at the corresponding temperature for a certain period of time. Therefore, the mutton deacidification environment control model needs to predict the temperature control curve of the corresponding deacidification chamber during the deacidification process according to the different types of carcasses. In the temperature control curve, the temperature is adjusted to a certain value, kept warm for a certain period of time, and then the temperature is raised or lowered according to the required conditions, and kept warm for a period of time. This pattern continues until the deacidification is completed.

[0113] Further, in step S2, the carcass classification model classifies mutton carcasses and generates carcass classification information. Specifically, the carcass classification model first performs primary classification based on breed, and then performs secondary classification based on weight and body shape for sheep of the same breed.

[0114] The aforementioned mutton aging control system and method achieves aging control tailored to individual mutton differences through the following setup: First, independent aging chambers 11 are set up within the aging chamber 1, and the environments of these chambers 11 remain independent and do not affect each other, providing a more precise aging space for different types of mutton. Second, RFID tags are affixed to the mutton carcass, and a first RFID scanner 6 and a second RFID scanner 7 are installed at appropriate locations within the aging chamber. A carcass classification model and a mutton aging environment control model are configured in the control device. The coordination between the different types of mutton carcasses allows them to be classified according to a specific criteria, ensuring that carcasses of the same type are placed in the same aging chamber 11, while different types are placed in different aging chambers 11. Third, by installing environmental parameter adjustment devices and data acquisition and monitoring devices inside or outside each aging chamber 11, the environmental parameters of each chamber can be monitored and adjusted in real time, ensuring independent operation of each chamber and thus enabling the classification and independent aging of mutton carcasses. Fourth... By installing a first intelligent control valve 17 at the location where the drip collection tank 16 penetrates the wall of the aging chamber 11, the aging chamber 11 is kept closed during the aging of the mutton carcass, ensuring the environmental independence between each aging chamber 11. After aging is completed, the first intelligent control valve 17 opens, allowing the drips generated during aging to be discharged from the aging chamber 11 into the drip collection box 15, preparing for the next aging process and ensuring that the environment for the new aging process is not affected by the previous one. Fifth, by installing a grid 14 on the floor of the aging chamber 1, the number of workers entering and exiting the aging chamber 1 is reduced. 1. By reducing the contamination of blood dripping from the mutton carcass, the industrial-grade pH sensor 40 can measure pH more accurately; 6. By setting up a baffle 18 and a drip guide 19, and positioning the industrial-grade pH sensor 40 at the drip guide 19, the flowing blood droplets can be measured, making the industrial-grade pH sensor 40's measurement more accurate; Therefore, compared with the existing technology of placing all mutton carcasses in a uniform aging environment for aging, this invention can perform personalized aging for different mutton individuals, improving the quality and taste of the mutton.

[0115] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.

Step 4: Model Optimization The above carcass classification model was deployed to an industrial computer. During subsequent optimization and training, the industrial computer used the carcass classification model to classify mutton carcasses. After the classification results were given, they were manually verified to check the classification results of the industrial computer and make improvements. Through iterative optimization and training of the carcass classification model over a certain period of time, a carcass classification model that can accurately classify mutton carcasses according to the priority order of classification criteria was obtained. The process of obtaining the aging environment regulation model for mutton is as follows: Step 1: Data Accumulation Before each aging process begins, the operator manually predicts the aging information of the carcass based on experience, namely the aging environment parameters and optimal aging time corresponding to each aging chamber in the aging room. During the aging process, the industrial control computer adjusts the environmental parameters according to the manual prediction and stops aging when the optimal aging time is reached. After aging is completed, the operator manually saves the carcass classification information in correspondence with the predicted values ​​of the aging environment parameters and the optimal aging time for each aging chamber. After aging is completed, the operator judges the quality of the predicted values ​​of the aging environment and the optimal aging time based on the condition of the mutton carcass after aging. If the aging condition is good, the carcass aging information corresponding to the aging chamber is placed in the folder of usable data; if the aging condition is poor, it is placed in the folder of unusable data. Step 2, Data Preprocessing: Once the carcass acid removal information in the aforementioned usable data folder has accumulated for a year or reached more than 500 records, Python software is used to preprocess the accumulated data. Step 3: Model Generation Based on the accumulated preprocessed data mentioned above, a regression model was selected as the classification model, and the scikit-learn library in Python was used to train the model to generate a mutton aging environment regulation model. Step 4: Model Optimization The aforementioned mutton aging environment control model was deployed to an industrial control computer. During subsequent optimization training, before aging began, the industrial control computer used the mutton aging environment control model to predict the aging information of the carcasses in each aging chamber, namely the aging environment parameters and the optimal aging time. During aging, the industrial control computer adjusted the environmental parameters according to the predicted aging environment parameters and stopped aging when the predicted optimal aging time was reached. After aging was completed, manual verification was performed to check the prediction results of the industrial control computer and make improvements. Through iterative optimization training of the mutton aging environment control model over a certain period of time, a mutton aging environment control model that can accurately predict the aging environment parameters and the optimal aging time was obtained.

8. A method for regulating the aging process of mutton, characterized in that, The mutton aging control system as described in any one of claims 1-7 includes the following steps: S0. Prepare the mutton carcass that needs to be deacidified. The mutton carcass is the mutton carcass with an RFID tag after slaughter. The RFID tag stores the basic information of the mutton carcass. S1. Start the control device, confirm that the environmental parameter adjustment device and data acquisition and monitoring device are in good working order, confirm that the sliding doors of each acid discharge chamber are in the open position, and all first intelligent control valves are in the closed position. S2. Workers push the prepared mutton carcasses through the double-door outer door into the transition room using a trolley. The first RFID scanner scans the RFID tags on the mutton carcasses and transmits the acquired basic carcass information to the industrial control computer. The carcass classification model classifies the mutton carcasses and generates carcass classification information. The first RFID scanner writes the carcass classification information into the corresponding RFID tags. At the same time, the mutton aging environment control model predicts the aging information required for this type of mutton carcass based on the carcass classification information. S3. The operator pushes the mutton carcass from the transition room into the inner door and hangs it on the hook. The second RFID scanner scans the RFID tag of the mutton carcass and transmits the data to the industrial control computer. The industrial control computer turns on the indicator light of the corresponding aging chamber according to the obtained carcass classification information. The operator pushes the mutton carcass into the corresponding aging chamber according to the guidance of the indicator light. S4. After all the mutton carcasses have been placed, the operators exit the aging chamber and report the completion of placement to the industrial control computer via the human-machine interface module; the industrial control computer then closes the sliding doors and indicator lights of all aging chambers. S5. The industrial control computer starts the acid removal process: Based on the predicted carcass acid removal information for each acid removal chamber and in conjunction with the feedback from the data acquisition and monitoring device, the industrial control computer starts to control the environmental parameter adjustment device to adjust the environment in each acid removal chamber accordingly. S6. During the aging process, the data acquisition and monitoring device monitors the environmental parameters, the pH value of the mutton carcass, and the pH value of the dripping liquid in each aging chamber in real time, and feeds them back to the industrial control computer. The industrial control computer compares the received data with the aging information of the carcass predicted by the mutton aging environment control model. If there is a deviation, the industrial control computer generates an adjustment command in time and sends it to the corresponding environmental parameter adjustment device for adjustment. At the same time, the industrial control computer sends the aging status of each aging chamber to the display screen for display, so that the operators can check it at any time. S7. When the aging process in a certain aging chamber is complete, the industrial control computer notifies the alarm device of the corresponding aging chamber to activate. The operator enters the aging chamber and, according to the alarm device's prompts, retrieves the mutton carcass from the corresponding aging chamber. As the mutton carcass leaves the aging chamber, the first RFID scanner writes the corresponding aging information into the RFID tag, and the status of the aging chamber on the display screen shows "completed". The operator then sends the aging-completed mutton carcass into the cold storage for preservation. S8. After all the mutton carcasses have been de-acidified and removed, the industrial control computer opens the first intelligent control valve to connect the drip collection tanks in each de-acidification chamber, so that the blood water generated during the de-acidification process flows into the drip collection tank. The operator then shuts off the mutton de-acidification control system, and the de-acidification process ends.

9. The method for regulating the aging process of mutton as described in claim 8, characterized in that: In step S6, the industrial control computer promptly generates adjustment commands and sends them to the corresponding environmental parameter adjustment devices for adjustment. Specifically, the industrial control computer controls the fan to adjust the airflow based on the feedback from the wind speed probe; the industrial control computer controls the opening of the second intelligent control valve at the connection between the humidification pipe and the acid discharge chamber wall based on the humidity feedback from the humidity probe, thereby adjusting the total amount of moisture entering the acid discharge chamber; and the industrial control computer controls the refrigeration unit or air heater to adjust the temperature based on the temperature feedback from the temperature sensor.

10. The method for regulating the aging process of mutton as described in claim 8, characterized in that, In step S2, the carcass classification model classifies mutton carcasses and generates carcass classification information. Specifically, the carcass classification model first performs primary classification based on breed, and then performs secondary classification based on weight and body shape for sheep of the same breed.
