Description

Technical Field

[0001] This invention belongs to the field of pig farming and processing technology, specifically relating to a method, system, equipment, and storage medium for controlling piglet feeding. Background Technology

[0002] With the rapid development of modern animal husbandry towards large-scale and intensive operations, the refined feeding and management of piglets has become a key link in improving breeding efficiency and ensuring animal health. In the early growth stages of piglets, especially when sows have a large litter size or insufficient milk production, artificial supplementation with milk powder has become an important means of ensuring piglets' nutritional intake. However, traditional artificial feeding methods generally suffer from problems such as high labor intensity, low operational efficiency, poor formulation accuracy, and difficulty in ensuring hygiene. This not only increases breeding costs but also easily affects piglets' digestion, absorption, and healthy development due to factors such as unsuitable milk temperature, uneven concentration, or cross-contamination.

[0003] Currently, while some automatic feeding devices have appeared on the market, most products have relatively simple functions and lack intelligent and coordinated control over the entire feeding process. For example, many devices can only provide water on a timed basis or perform simple stirring, and cannot dynamically adjust the ratio of milk powder to warm water according to the piglets' age; some systems have heating functions, but the temperature control precision is insufficient, making it difficult to maintain the milk at a constant drinking temperature; existing devices generally lack power outage recovery mechanisms, which can easily lead to missed feeding schedules after a sudden power outage, affecting the continuity of feeding. In addition, most automatic feeding devices do not integrate effective self-cleaning functions, and residual milk can easily breed bacteria in the pipeline, posing a significant biosafety risk.

[0004] Therefore, there is an urgent need for a new method and system for controlling piglet feeding, in order to achieve full automation and intelligence of the entire process from warm water supply, milk powder addition, mixing and stirring to milk delivery and equipment cleaning, thereby effectively improving the quality of feeding, ensuring the health of piglets, and providing reliable technical support for modern pig farms. Summary of the Invention

[0005] The main objective of this invention is to provide a method, system, device, and storage medium for controlling piglet feeding, in order to solve or partially solve the problems pointed out in the background art. To this end, this invention provides the following technical solution:

[0006] In a first aspect, the present invention provides a method for controlling piglet feeding, comprising:

[0008] Start the milk powder conveying mechanism to deliver the preset weight of milk powder to the milk can, and then turn off the milk powder conveying mechanism.

[0009] Turn on the air compressor to spray compressed air from the bottom of the milk container, stir the milk powder and warm water for the preset time, then turn off the air compressor to obtain milk;

[0010] Turn on the valve and delivery pump at the bottom of the milk container to pump the milk outwards, thus completing the milk feeding.

[0011] In at least one embodiment, the execution instruction uses time as a trigger signal and is automatically started when a preset time is reached; this time corresponds to the age of the piglets and is used to update data according to the time, the data including the amount of milk powder used at different ages and the amount of warm water used to match the amount of milk powder used.

[0012] In at least one embodiment, a heating module and a temperature sensor are installed inside the water tank. By receiving the detection signal from the temperature sensor in real time, the heating module is controlled to maintain the water temperature in the water tank within a preset range. The inlet of the water tank is connected to an external water pipe and is equipped with an inlet valve. A liquid level sensor is installed inside the water tank. By receiving the detection signal from the liquid level sensor in real time, the inlet valve is controlled to maintain the water level in the water tank within a preset range.

[0013] In at least one embodiment, a flow meter is installed at the outlet of the water tank, and the weight of the delivered warm water is calculated based on the flow rate fed back by the flow meter.

[0014] In at least one embodiment, the milk powder conveying mechanism includes a hopper, a spiral blade disposed at the bottom of the hopper, a motor for driving the spiral blade to rotate, and a weighing platform disposed below the hopper. The milk powder entering the hopper is conveyed to the inlet of the milk bucket by the spiral blade through the motor, and the milk powder is weighed based on the weight loss information fed back by the weighing platform.

[0015] In at least one embodiment, after the milk feeding is completed, the air compressor is started to introduce compressed air into the pipe at the bottom of the milk container for rinsing. After rinsing for a preset time, the air compressor is turned off.

[0016] In at least one embodiment, the piglet feeding control method further includes power outage correction, which includes:

[0017] Preset the feeding cycle corresponding to the piglets' age;

[0018] Record the time of each successful execution of the instruction, and store at least the time Tl of the last successful execution;

[0019] Each time the power is turned on, calculate the number of times n should be executed between Tl and the current time, based on the time interval between feeding cycles;

[0020] If n≥1 times, it is marked as pending execution once and enters the pre-execution phase, with a waiting time of Tw.

[0021] The execution is confirmed by the operator during the waiting period of the pre-execution phase, or it is executed automatically after the waiting period reaches Tw.

[0022] Update the current execution time to the most recent execution time, or allow the operator to adjust the most recent execution time.

[0023] Secondly, the present invention provides a piglet feeding control system, comprising:

[0024] The water tank has a water pump at its outlet to provide warm water;

[0025] Milk powder conveying mechanism, used to convey milk powder;

[0026] The milk container is connected to an air compressor, and the bottom pipes are equipped with valves and a delivery pump;

[0028] Thirdly, the present invention provides a piglet feeding control device, including a memory and a processor, wherein the memory stores a program, and the program is read and executed by the processor to perform the piglet feeding control method described above.

[0029] Fourthly, the present invention provides a computer-readable storage medium having a program stored thereon, the program being executed by a computer to perform the above-described piglet feeding control method.

[0030] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0031] 1. Improve feeding efficiency: Through automated processes, including automatic watering, milk powder delivery, mixing and feeding, the need for manual intervention is significantly reduced, labor intensity is lowered and work efficiency is improved.

[0032] 2. Precise control of milk volume and temperature: The flow meter is used to accurately measure the weight of warm water, and the amount of milk powder and the ratio of warm water are adjusted according to the needs of piglets of different ages to ensure that the amount and temperature of milk prepared each time meet the optimal feeding standards, which helps to promote the healthy growth of piglets.

[0033] 3. Intelligent management: It can automatically update data and adjust feeding parameters according to the age of piglets; in addition, the power failure correction function ensures that the operation can maintain continuity and accuracy even in the event of an unexpected power outage.

[0034] 4. Improved hygiene: Using an air compressor for mixing and rinsing not only ensures that the milk powder and warm water are fully mixed, but also allows for effective cleaning of the equipment after feeding, greatly improving the hygiene of the equipment and helping to reduce the risk of disease transmission.

[0035] 5. High adaptability: The system design takes into account the specific needs of piglets at different growth stages, and has good flexibility and adaptability. It can meet the specific needs of different farms and improve breeding efficiency.

[0042] Figure 5 This is a structural block diagram of a piglet feeding control device provided in an embodiment of the present invention. Detailed Implementation

[0043] The present invention will now be described in detail with reference to exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present invention more complete and to fully convey the inventive concept to those skilled in the art.

[0044] First, refer to Figure 1 This invention provides a method for controlling piglet feeding, comprising the following steps:

[0045] S1. Issue an execution command to turn on the water pump at the water tank outlet, deliver a preset weight of warm water to the milk bucket, and then turn off the water pump.

[0046] S2. Start the milk powder conveying mechanism, convey the preset weight of milk powder to the milk can, and then turn off the milk powder conveying mechanism.

[0047] S3. Start the air compressor to spray compressed air from the bottom of the milk container, stir the milk powder and warm water for the preset time, and then turn off the air compressor to obtain milk;

[0048] S4. Open the valve and delivery pump at the bottom of the milk container to pump the milk outwards and complete the milk feeding.

[0049] In step S1, the execution instruction uses time as the trigger signal and is automatically started when the preset time is reached; this time corresponds to the age of the piglets and is used to update data according to the time, the data including the amount of milk powder used at different ages and the amount of warm water used to match the amount of milk powder used.

[0050] The system uses time as the trigger signal for execution instructions, and can be accurate to the hour, minute, and second as the start signal. At the same time, the system can automatically calculate the amount of milk powder and warm water used for piglets of different ages based on the time-updated data, thereby adapting to piglets of different ages and ensuring that piglets receive sufficient nutrition.

[0051] If time is used as the startup signal, the next startup signal will also automatically refresh the time node. If the power outage time happens to coincide with the startup time node, it will cause the startup to be skipped, and the next startup time will not be refreshed. This leads to the drawback that the program can only continue running after 24 hours without modification. Therefore, refer to... Figure 2 The method also includes power outage correction, which includes:

[0052] Preset the feeding cycle corresponding to the piglets' age;

[0053] Record the time of each successful execution of the instruction, and store at least the time Tl of the last successful execution;

[0054] Each time the power is turned on, calculate the number of times n should be executed between Tl and the current time, based on the time interval between feeding cycles;

[0055] If n≥1 times, it is marked as pending execution once and enters the pre-execution phase, with a waiting time of Tw.

[0056] The execution is confirmed by the operator during the waiting period of the pre-execution phase, or it is executed automatically after the waiting period reaches Tw.

[0057] Update the current execution time to the most recent execution time, or allow the operator to adjust the most recent execution time.

[0058] The core issue is the insufficient robustness of time-triggered programs in power outage / reboot scenarios. The program gets stuck "waiting for a time that will never arrive," requiring a 24-hour time loop before it can match again. The power outage correction process of this invention does not rely on a "precise time trigger + single update" mechanism, but instead adopts a strategy of "dynamic judgment based on the current time + execution state memory," ensuring that state variables are retained even after power outages, thereby resolving the technical problem.

[0059] Moreover, the above power outage correction process closely matches the actual feeding process in pig farms: 1. As piglets grow older, the amount of feed required increases, the feeding intervals also adjust, and the ratio of milk powder to water may change, so it is necessary to preset feeding cycles for different age groups; 2. Executing the process even if n>1 is to avoid overly complex procedures, and under normal circumstances, it is unlikely that situations will occur where piglets are fasted for a long time without being detected. Also, the amount and frequency of feed intake for piglets at one time should not be excessive; 3. Setting a pre-execution phase is mainly due to the fact that farms generally have on-duty personnel. 4. Personnel are generally recorded and feedback is provided when power outages occur in farms or equipment, allowing staff to handle the situation promptly. Equipment and materials are checked before restarting to prevent unforeseen circumstances. 5. Automatic operation is only initiated after a certain time (Tw), allowing staff time to troubleshoot and preventing excessive waiting or staff forgetting to confirm execution, ensuring milk supply to piglets. 6. The latest execution time retains a manual adjustment program to ensure consistent daily feeding times after adjustments.

[0060] The water tank is equipped with a heating module and a temperature sensor. By receiving the detection signal from the temperature sensor in real time, the heating module controls the water module to maintain the water temperature in the tank within a preset range. The water tank inlet is connected to an external water pipe and equipped with an inlet valve. A liquid level sensor is installed inside the tank. By receiving the detection signal from the liquid level sensor in real time, the inlet valve controls the water level in the tank to maintain it within a preset range. In one specific embodiment, one liquid level sensor can be installed at a high position and one at a low position, thereby controlling the liquid level between the two. Generally, because the water tank has a sufficiently large volume, during a single supply of warm water, the water volume is sufficient, and a water replenishment operation can be initiated after the water supply is completed.

[0061] Furthermore, a flow meter is installed at the outlet of the water tank, and the weight of warm water being delivered is calculated based on the flow rate fed back by this flow meter. Additionally, a flow meter can also be used at the bottom of the milk container to achieve precise control of the feeding amount.

[0062] In step S2, refer to Figure 3 The milk powder conveying mechanism includes a hopper, a spiral blade set at the bottom of the hopper, a motor for driving the spiral blade to rotate, and a weighing platform set below the hopper. The milk powder entering the hopper is conveyed to the inlet of the milk bucket by the spiral blade through the motor and the milk powder is weighed based on the weight loss information fed back by the weighing platform.

[0063] The aforementioned milk powder conveying mechanism adopts a structure of "hopper + spiral blades + motor + weighing platform," and achieves accurate measurement of milk powder through the weight reduction information fed back by the weighing platform. It has the following significant advantages:

[0064] 1. High-precision metering: By monitoring the weight reduction of the hopper and the milk powder inside during the conveying process in real time (i.e., the weight reduction method), the actual quality of the conveyed milk powder can be obtained directly and accurately. This avoids the errors caused by factors such as fluctuations in milk powder density, clumping, or changes in humidity in volume measurement, and significantly improves the accuracy of the mixing ratio.

[0065] 2. Simple and reliable structure, easy to maintain: The spiral conveyor system composed of spiral blades and motor has a compact structure and runs smoothly, making it suitable for quantitative conveying of powdery materials (such as milk powder); at the same time, the weighing platform is independently set under the hopper and is not directly coupled with moving parts, which reduces mechanical interference and improves weighing stability and equipment life.

[0066] 3. Strong closed-loop control capability: The system can dynamically adjust the motor running time or speed according to the real-time weight loss data fed back by the weighing platform, realizing closed-loop control of "conveying and calibrating at the same time", ensuring that the amount of milk powder added each time strictly meets the preset value, which is especially suitable for the fine control needs of milk concentration for piglets of different ages.

[0067] 4. Preventing residue and cross-contamination: The screw conveyor can effectively empty the milk powder in the hopper, reducing residue; combined with the subsequent compressed air rinsing step, the conveying channel can be further cleaned, ensuring hygiene and safety and reducing the risk of cross-contamination between batches.

[0068] In step S3, the milk powder is mixed by using an air compressor, which utilizes the principle of agitation of liquid when air rises, replacing the mechanical stirring structure. This simplifies the design and has the following advantages:

[0069] 1. Uniform mixing and thorough dissolution: Compressed air is sprayed upwards from the bottom of the milk container, creating strong gas-liquid disturbance and tumbling effect, which can effectively break up the agglomeration of milk powder particles, promote their rapid and uniform dispersion and dissolution in warm water, avoid clumping or sedimentation, and ensure that the prepared milk has a consistent concentration and uniform texture.

[0070] 2. No mechanical stirring parts, simplified structure, and easy to clean: Traditional stirring usually relies on motor-driven paddles or stirring rods, which are not only complex in structure but also have hard-to-clean corners that are prone to bacterial growth. In contrast, compressed air stirring eliminates the need for moving parts inside the milk tank, resulting in a simple and smooth internal structure that facilitates subsequent rinsing. This significantly improves the hygiene level of the equipment and meets the high requirements for food safety and biosecurity in aquaculture environments.

[0071] 3. Avoid introducing sources of contamination: Since the mixing process is completed entirely by clean compressed air, no additional lubrication or seals are needed in the milk contact area, reducing the risk of contamination caused by mechanical wear or seal failure and ensuring the safety of piglets drinking milk.

[0072] 4. Precise control and good repeatability: The mixing time can be precisely set by the program. Combined with the automated control system, the parameters of each mixing process are consistent, ensuring the stable quality of milk in different batches, which is conducive to the regular feeding and healthy growth of piglets.

[0073] In step S4, after the milk feeding is completed, the air compressor is started to introduce compressed air into the pipe at the bottom of the milk container for rinsing. The air compressor is then turned off after the rinsing has reached a preset time. This method has the following advantages:

[0074] 1. Effectively cleans residual milk, preventing blockages and spoilage: Milk contains organic components such as protein and fat. If it remains in the pipes or at the bottom of the milk container, it can easily breed bacteria, ferment and spoil, and even dry and form deposits, causing blockages. Powerful blowing with compressed air can effectively remove residual liquid and deposits, keeping the flow channels clear.

[0075] 2. No additional cleaning solution required, saving resources and being environmentally friendly: Cleaning is done by "air flushing" with compressed air, eliminating the need for water or other cleaning agents. This saves water resources, avoids the impact of cleaning solution residue on the quality of the next milk preparation, and reduces wastewater discharge, which is in line with the concept of green farming.

[0076] 3. Shares equipment with the mixing system, resulting in high structural integration: This rinsing function reuses the existing air compressor and bottom pipeline, eliminating the need for a dedicated cleaning pump or nozzle, simplifying the system structure, and reducing manufacturing costs and maintenance complexity.

[0077] Secondly, refer to Figure 3 The present invention provides a piglet feeding control system, which includes:

[0078] The water tank has an outlet pump to provide warm water;

[0079] Milk powder conveying mechanism, used to convey milk powder;

[0080] The milk container is connected to an air compressor, and the bottom pipes are equipped with valves and a delivery pump;

[0081] The controller is used to execute the above-described piglet feeding control method.

[0082] The controller is generally a PLC controller, and the available models include, but are not limited to: Siemens S7-1200 series, Mitsubishi Electric FX5U series, Omron CP1H / CJ2M series, INOVANCE H3U / H5U series PLC, Xinje XD / XL series PLC, and Delta DVP-ES3 / EX3 / SX2 series.

[0083] In addition, the piglet feeding control system can be equipped with a touchscreen connected to the controller for human-machine interaction and adjustment of various parameters. The touchscreen interface can include a production interface, manual interface, flow meter calibration interface, usage interface, parameter interface, historical data interface, alarm interface, and temperature interface. Detailed parameters such as time, temperature, usage, historical data, and alarm information can be viewed on the touchscreen for easy monitoring of usage status. It also features detailed annotations to facilitate quick and easy user operation.

[0084] In one specific embodiment, the following operations can be performed via the touchscreen:

[0085] 1) Parameter settings

[0086] 1.1) After the initial settings of various parameters are completed, subsequent use can be based on the adjusted parameters, and the adjusted parameters will be automatically included in the calculation. Parameters such as start time and age will automatically increase as the usage process progresses. Interval time, stirring time, etc. can also be set to improve the flexibility of the equipment and make it more convenient and reasonable to use.

[0087] 1.2) Some parameters involving data reading and data conversion are fixed programs, while the parameters involving temperature control are not adjustable. They are only put into use after being adjusted. Arbitrary adjustment will lead to large temperature fluctuations, and inaccurate temperature will lead to abnormal heating.

[0088] 1.3) The parameters of the flow meter need to be calibrated multiple times to obtain the parameter values. After a long period of use, the parameters also need to be recalibrated. The calibration process also requires multiple calibrations to obtain the K coefficient.

[0089] 2) Manual adjustment

[0090] 2.1) The manual interface can test whether each function is normal. There are indicator lights next to the buttons to check whether the coil is activated, which facilitates troubleshooting.

[0091] 2.2) During automatic program operation, the startup status can also be viewed through the coil indicator lights on the manual interface. The indicator lights also indicate the specific step the automatic program has reached.

[0092] 3) Alarm prompts

[0093] 3.1) Alarm prompts are set up for insufficient milk powder, abnormal water addition, abnormal milk addition, abnormal milk pumping, etc. When an alarm is triggered, the alarm interface will automatically jump to display the text prompt with the specific alarm content, and the automatic program will stop to protect the motor and pump and prevent damage from prolonged idling. The alarm will automatically clear after the fault is handled.

[0094] 3.2) The alarm output is connected to a buzzer, which can be manually silenced or automatically silenced by the program after the fault is dealt with.

[0095] 4) Historical Reports

[0096] Each time the automatic program starts, it will generate a report on the amount of milk powder used. The report will clearly indicate the amount used and the time points, making it easy to check the usage and verify the data later.

[0097] This piglet feeding control system can realize a series of automated processes including milk preparation, feeding, and cleaning. The amount used in the process can be precisely controlled, saving labor costs. Precise control of the amount used can also enable scientific and convenient breeding. The automatic milk preparation machine can also work in a one-to-many manner, rather than operating in a single operation, which is both convenient and efficient.
