Description

Technical Field

[0001] The present application relates to the field of animal husbandry automation, and in particular to an adaptive pig feeding system and method. Background Art

[0002] The working principle of pig feeding products on the market is to manually formulate the water-to-feed ratio and feeding rules, and then execute them mechanically. This is inefficient and does not obtain data on factors affecting the pigs' feeding intake at this meal to self-correct the supply. It is difficult to meet individual differences and easily leads to feed waste.

[0003] With the development of animal husbandry, precision feeding technology has gradually attracted attention. Its core is to meet the nutritional needs of pigs at different growth stages through scientific nutritional formulas and precise feeding methods. However, due to its complex equipment system, precision feeding technology is prone to failure, which may affect the normal operation of the entire feeding system. In large-scale pig farming, due to the large number of pigs, it is impossible to measure the height, weight, length, and width of each pig in a timely manner, making it impossible to adjust the feed supply according to the pig's weight and growth stage.

[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0051] In an exemplary embodiment, Figure 1 As shown, an adaptive pig feeding system is provided, whose main structure is a stainless steel frame and a barrel. The adaptive pig feeding system includes: a sensing detection module, an instant hot water module, a core control module and a power execution module.

[0052] The sensing detection module is used to obtain pig feeding environment information and weak pig information; the pig feeding environment information includes: water supply temperature and feed remaining amount in the feed basin.

[0053] The instant hot water module is connected to the sensing and detection module and is used to heat water to a preset temperature based on information about the pigs' feeding environment. This allows the adaptive pig feeding system to provide temperature-controlled hot water, preventing diarrhea caused by excessive cold water intake in winter.

[0054] The core control module is connected to the sensing and detection module and the instant hot water module. Based on the input feeding mode, water-to-feed ratio, and pig feeding environment information, combined with a temperature compensation algorithm, the core control module adjusts the water-to-feed ratio. Furthermore, it obtains feeding instructions based on weak pig information. The feeding modes include dry feed mode, porridge quantitative feeding mode, porridge meal feeding mode, porridge ad libitum feeding mode, and mixed feeding mode. The porridge quantitative feeding mode is calculated by multiplying the number of revolutions of the feed motor by a calibration parameter (e.g., 8.5 revolutions / cycle).

[0055] The power execution module is connected to the core control module; the power execution module is used to discharge materials and supply water based on the adjusted water-to-material ratio and feeding instructions.

[0056] As an implementation method, the core control module is a main control box, which includes a display screen, mechanical buttons, fuses, alarm lights, fuses, waterproof three-core power plugs and a control panel. The main control box is equipped with a feeding motor, a water discharge solenoid valve and a sensor rod. The control panel uses 6 mechanical buttons, including: 1 setting button, 1 water-to-feed ratio button, 1 feeding / feed control time button, 1 "increase" button, 1 "decrease" button and 1 confirmation button. The setting button can set pig parameters (pig age and number of pigs) and synchronize with the cloud platform, select manual feeding and manual discharge, calibrate the feed amount, set the communication and lock screen, view the control box version information and historical data (start date, batch information, number of pigs, cumulative feed intake and average feed intake per head, etc.) and set the feeding mode. The core control module sets different feeding curves according to different breeds, different stages and different needs of the pig group, and sets a scientific and reasonable feeding mode. The main control box is equipped with feeding modes including dry feed mode and porridge feed mode (free feeding mode, meal feeding mode, and quantitative feeding mode), as shown in Table 1. The management personnel adjust the water-to-feed ratio to 2.0:1 or 2.5:1 based on the age of the pigs. The water-to-feed ratio button is used to set the water-to-feed ratio and adjust the water data based on the water-to-feed ratio. During the adjustment process, it increases or decreases in units of 0.1, and the setting range is 1 to 5; the feeding / feed control time button makes the feeding time parameter flash by pressing the button once. Press to increase or decrease to modify it. Press the button again to make the feed control time parameter flash. Press to increase or decrease to modify the parameter. Press to confirm and save. The time is adjusted in units of 5 minutes. The feeding / feed control time can be 1.5:1, 3.5:4, and 3:4.5; the increase and decrease buttons adjust one unit when pressed alone, and continuous adjustment is made when pressed for 3 seconds or more.

[0057] Table 1 Water-to-feed ratio for pigs at different ages

[0058]

[0059] When the main control box is powered on, the display screen shows version information, current software version information, and customization. After 3 seconds, it enters the main page, which displays information such as the perpetual calendar, pig age, number of pigs, feeding mode, cumulative feed intake, today's feed intake, and number of meals eaten. If there is no operation within 60 seconds, the main control box enters a lock screen state, extinguishing the screen. Touching any button will illuminate the interface. The main control box can be operated and adjusted at any time. When the main control box is locked, pressing the two combination buttons on the main control box for more than 3 seconds will unlock the main control box before making settings or adjustments. Adjustments can also be made by turning the machine off and on.

[0060] The perpetual calendar displayed on the main control box's display changes with the passage of time and is unaffected by operating status, working mode, alarm status, shutdown status, or power outages. The pig's age changes with the passage of time, cycling from 20 to 300 days. The perpetual calendar automatically adjusts to the pig's age, regardless of the operating status, working mode, alarm status, shutdown status, or power outages. The menu on the main control box's display allows for manual feeding, with the number of feed revolutions per manual feed cycle set for convenient calibration and emergency feeding. By default, each manual feed cycle results in five motor revolutions. Between 11 PM and 3 AM, feed control is in effect regardless of manual or automatic mode. However, if the feed is switched to manual feeding or manual watering during this time, the feeder automatically enters manual feeding or manual watering mode after 5 seconds, returning to the empty feed state. The absolute feed control time can be adjusted from the host computer (0:00 to 24:00), and the corresponding setting information is displayed on the main control box's display.

[0061] As an embodiment, the sensing detection module includes: a water temperature sensor, a sensing rod, and an image acquisition device. The image acquisition device is a camera.

[0062] The water temperature sensor is connected to the core control module and is used to obtain the water supply temperature. The water temperature sensor monitors the water supply temperature and dynamically adjusts the water-to-stock ratio. Specifically, the water temperature sensor detects the current water supply temperature in the pen and automatically adjusts the water-to-stock ratio.

[0063] The sensing rod is connected to the core control module; the sensing rod is used to obtain the feed remaining in the feed bowl and control the feeding / stopping of the feed based on the feed remaining in the feed bowl.

[0064] In an exemplary embodiment, the sensing rod includes a connecting rod and a probe, the wire is located in the connecting rod, and a probe is provided at one end of the connecting rod. The probe is connected to the main control box through the wire. The conductivity of the wet feed in the feed bowl is used to determine whether it is connected, and the remaining feed in the feed bowl is determined based on the conductivity of the probe.

[0065] The image acquisition device is connected to the core control module; it is used to capture images of pigs eating and, based on these images, to identify weak pigs and the remaining feed in the feed bowl. The camera identifies the ratio of pigs eating and weight deviation based on these images, triggering a refeed instruction to extend the feeding time or increase the feeding cycle. The camera also captures the remaining feed in the feed bowl, monitors the pigs' behavior, analyzes their feeding desire, and calculates the new feed amount.

[0066] The core control module verifies the remaining feed in the basin, as measured by the sensing rod, against the remaining feed in the basin, as determined by the image acquisition device. The camera and water temperature sensor communicate with the main control box via a data interface. The sensor rod conducts conductivity and the camera visually verifies the remaining feed threshold. If the remaining feed falls below 50% of the basin's volume, the feed is automatically refilled.

[0067] In an exemplary embodiment, if the core control module determines that the difference between the feed remaining in the bowl obtained by the sensing rod and the feed remaining in the bowl determined by the image acquisition device is less than 5%, the feed remaining in the bowl is determined by averaging the feed remaining in the bowl obtained by the sensing rod and the feed remaining in the bowl determined by the image acquisition device; if the core control module determines that the difference between the feed remaining in the bowl obtained by the sensing rod and the feed remaining in the bowl determined by the image acquisition device is greater than or equal to 5%, it may be that an error occurs in the process of obtaining the feed remaining in the bowl, and the sensing rod is controlled to re-acquire the feed remaining in the bowl and the image acquisition device is controlled to re-determine the feed remaining in the bowl based on the image of the pig eating.

[0068] The specific description of the precise feeding control and water-feed ratio adjustment functions is as follows: in dry feeding mode, only the feeding motor is added, and no water is added, which meets the requirements of pure dry feeding; its dry feed control logic is to monitor the feed remaining in the feed bowl through the sensor rod and camera. When the feed remaining in the feed bowl is less than half of the feed bowl volume by default, the feed is automatically added, and the feeding is stopped when the feed is greater than or equal to half of the trough volume (several positioning points are set around the 1 / 2 of the feed bowl volume, and the remaining feed is calculated by monitoring the positioning points to see whether it meets the feeding requirements); in meal feeding mode, the administrator can set the number of meals to be fed and the feeding time for each meal according to the current pig age, number of pigs to be fed, average weight of pigs, nutritional formula and other parameters. The administrator can set the meal feeding mode on the display as follows: (1) Basic parameters: pig category; age, number of pigs, average weight / head, nutritional ratio (ratio of feed nutrition and supply), feed category (pellet feed); (2) Environmental parameters: temperature; (3) Feeding parameters: Feeding mode selection: dry feed feeding / porridge feed feeding / mixed feed mode, porridge feed feeding: free feeding mode / meal feeding mode; Meal feeding: quantitative supply: yes / no; Meal one: ___%, Meal two: ___%, Meal three: ___%, increase / decrease meal times, and fill in the theoretical supply cumulatively 50%-100%.

[0069] Specifically, the power execution module includes: a blanking motor and a solenoid valve.

[0070] The material discharge motor is connected to the core control module; the material discharge motor is used to discharge the material based on the adjusted water-to-material ratio and the material replenishment instruction.

[0071] The solenoid valve is connected to the core control module and is used to supply water based on the water-to-material ratio. It uses a PWM power supply mode with a voltage of 78V. The manual release solenoid valve is powered by a voltage between 23-24V, while the release voltage is between 21-22V.

[0072] In an exemplary embodiment, the adaptive pig feeding system further includes a music player module;

[0073] The music player module is connected to the core control module.

[0074] The core control module determines whether the pig is in a feeding state based on the pig eating image; when the pig is in a feeding state, the core control module generates a music playing instruction.

[0075] The music player module is used to play music based on the music playing instruction. The music player module is integrated into the core control module and plays music when the pigs are eating, which can reduce the stress response of the pigs.

[0076] In an exemplary embodiment, the core control module is also used to receive the working status of the unloading motor and the sensing rod, judge the abnormal mode of the unloading motor and the sensing rod based on the working status of the unloading motor and the sensing rod, and generate emergency instructions based on the abnormal mode of the unloading motor and the sensing rod, and control the unloading motor to unload with different working cycles based on the emergency instructions.

[0077] Specifically, when the main control box detects a high current protection state, a water shortage alarm, or an abnormal feed motor, it displays an abnormal feed motor and sensor bar pattern. The main control box then uploads the ID of the main control box connected to the feed motor and sensor bar to the host computer and issues an alarm. During the alarm process, the main control box displays the alarm code, stops operating, and the alarm indicator flashes. The alarm information is uploaded to the web client. If the device re-enters the feeding state and feeding is normal, the host computer clears the alarm.

[0078] Specifically, 200ms after the feeding motor starts running, the value is detected every 1s for 3 consecutive times. If the 3 values ​​are greater than 2400 (5.8A), the display screen will show high current protection (refer to the first generation of nursery and fattening integrated machine for protection method), and the alarm reason is high current protection (stall) of the feeding motor; in the feeding state, the water temperature is detected for 10s and there is no temperature change, it is judged that there is no water, and the equipment will alarm if the sensing rod is still not connected for 35 small cycles of feeding; when the sensing rod is connected, the 35 small cycles will be counted again; if there is a gear adjustment operation, it needs to be restarted. The conditions for clearing the water shortage alarm include: 1. Powering off and then powering on the device, allowing it to re-enter the feeding state; 2. The alarm is cleared when parameters are sent from the upper computer, allowing it to re-enter the feeding state; 3. If no one operates the lower computer for 3 hours after the alarm, the lower computer restarts and re-enters the feeding state. If the alarm continues after re-entering the feeding state, no upload to the upper computer is required. Feeding will resume normally after 1 hour of restarting, and the upload alarm is cleared. Failure to detect the Hall effect signal of the feeding motor indicates an abnormality. Detecting fewer than 500 Hall effect signals after 35 seconds of feeding indicates an abnormality, triggering a motor signal abnormality alarm. The conditions for clearing the motor abnormality alarm include: 1. Powering off and then powering on again clears the alarm, allowing it to re-enter the feeding state. 2. If no one operates the lower computer for 30 minutes after the alarm, the alarm is cleared, allowing it to re-enter the feeding state. If the alarm continues after re-entering the feeding state, no upload to the upper computer is required. Feeding will resume normally after 10 minutes of restarting, and the upload alarm is cleared.

[0079] As an implementation method, the system adds adjustable loop counts for the water-free alarm and the short unloading cycle, and adopts PWM power supply for solenoid valve adjustment. Adjustments to the material quantity calibration lower computer are made by incrementing 10g each time. During customer use, if a probe anomaly causes the power execution module to fail to unload or control the material, rendering the unloading motor inoperable, emergency measures are implemented. The cloud platform menu includes abnormal mode processing, including normal feeding mode, probe abnormality feeding mode, and motor Hall abnormality feeding mode. When in probe abnormality feeding mode, the unloading motor cycle is set to 3 minutes for unloading and water supply, and the control time still implements no water unloading and no unloading. When in motor Hall abnormality feeding mode, the unloading motor unloads material based on time, i.e., the unloading cycle is 12 seconds. All other operations are consistent with normal feeding mode.

[0080] In one exemplary embodiment, the cloud platform can configure the building, unit, equipment number, number of pigs fed, age, feeding mode, feeding curve, water-to-feed ratio, feeding duration, and feed control duration. Feeding curves can be configured based on a combination of two or more feeding modes, and multiple feeding curves can be saved for later use. The cloud platform can also remotely lock the main control box. Once locked, the main control box's display will display: "Current device locked. Please contact the manufacturer to unlock."

[0081] like Figure 2As shown, the number of meals, feeding time period for each meal, feeding duration, interval duration can be set through the time axis, and multiple feeding curves can be saved for subsequent direct selection and call; the starting age to the ending age correspond to different feeding meals, feeding duration, interval duration or free feeding, water-to-feed ratio and number of pigs; the starting age to the ending age settings can be increased or decreased arbitrarily, corresponding to the feeding mode and the water-to-feed ratio; after being sent to the main control box, the system automatically executes according to the settings and switches to different modes; multiple feeding curves can be set according to age, feeding mode, feeding meals, interval time, etc.

[0082] As an implementation method, the main control box directly controls the local device, and the main control box is connected to the intermediate server (gateway) through the LoRa module. The gateway is connected to the cloud platform through 4G / WiFi / network cable. A single gateway supports 60 lower-level cloud platforms. The cloud platform can connect to multiple gateways without limit to achieve large-scale networking. The LoRa module realizes low-power long-distance communication between the lower-level computer and the gateway. LoRa can transmit with anti-interference in complex rural environments. LoRa has a breakpoint resumption mechanism. After power failure, unfinished cycle data is discarded and recounted after recovery.

[0083] This application also sends parameters in batches to the gateway through the cloud platform, and the gateway synchronizes to the main control box. The main control box transmits the status in real time (supports operations such as locking the device and forced restarting) for remote management. As shown in Table 2, when the feeding mode is in quantitative feeding mode, the daily feed supply, number of pigs, number of meals per day and meal times for each pig can be set through the cloud platform and sent to the lower computer (main control box). The parameters that need to be set and sent by the cloud platform in different modes are independent of each other and synchronized to the main control box through the gateway. The cloud platform also has the function of counting the number of feeding motors in each unit of all buildings, the total number of pigs, the number of pigs in a single unit, the cumulative feed consumption, the number of pigs in each stage and the number of pigs that died; after the number of pigs in each day of the main control box is changed, it is uploaded to the upper computer for synchronization based on the data upload rules. The upper computer also needs to make corresponding changes. The upper computer can uniformly adjust and proofread the feeding / feed control time. The web terminal only collects and analyzes data, and can send relevant information such as the number of pigs, age, feed type, etc. in batches or individually; it can also send feed quantity calibration data in batches.

[0084] Table 2 Description of cloud platform

[0085]

[0086]

[0087] As an implementation method, the web terminal can view the feed intake of each meal, that is, the feed intake and feeding time of each feeding period, the feed intake of the day (referring to the total feed intake from 0:00 to 24:00 on that day), the cumulative feed intake (referring to the total feed intake of the feeding motor from the time it was used to the present), the number of pigs on that day, the average feed intake, the current equipment status (feeding period, feed control period), the current feeding mode, the age of the pigs, and the cumulative number of days and feed intake. The daily feeding curve, weekly feeding curve and design report can be generated based on the number of days and feed intake. The design report is filled in with the number of pigs, feeding days, total feed intake and weight. The total electricity consumption cost, total water cost and labor cost are filled in manually. Based on the design report, the average daily weight gain from the beginning to the present, the average feed-to-meat ratio, breeding costs, etc. are automatically generated. Daily feed intake refers to each feeding period as one meal. For example, if the feeding period is 8:00-9:00, all feeds added during this period are the first meal; each meal is similarly divided into two groups. If the power is cut off and then restored, it is the next meal (manual feeding is not included in the feed intake). In any feeding mode, if you adjust the feeding time interval, water-to-feed ratio, or adjust the number of pigs, age, or feed type to start feeding, the number of meals will remain unchanged. In any feeding mode, if you adjust any feeding gear, or adjust the number of pigs, age, or feed type to start feeding, the number of feeding meals will increase by 1 (if the feed control state is changed to the feeding state, the number of meals will increase by 1).

[0088] The amount of food consumed is uploaded to the host computer once at the end of each small feeding cycle. The host computer accumulates the amount of food consumed in that meal. If there is a power outage during feeding, the amount of food consumed in that small feeding cycle does not need to be uploaded; the feeding time and the empty feeding time can be uploaded when switching.

[0089] As shown in Table 3, the system of this application enters the theoretical supply table, the number of heads fed per unit, the standard is 50 heads, and the nursery / fattening method automatically adjusts the total daily supply based on the number of heads fed. A benchmark is customized based on the nutritional formula. If the benchmark is exceeded, the nutritional ratio is less than 1, and the daily supply is reduced accordingly. If it is lower than the benchmark, the ratio is greater than 1, and the daily supply is increased. Based on the theoretical supply table for pigs, a mixed feeding mode can be obtained, which means that a variety of feeding modes are combined to form a feeding curve during the entire nursery and fattening stage; for example: pigs in the 21-50 day age group adopt a porridge free feeding feeding mode; pigs in the 51-90 day age group adopt a porridge meal unquantified feeding mode; pigs in the 91-180+ day age group adopt a porridge meal quantitative feeding mode.

[0093] In an exemplary embodiment, Figure 3 As shown, an adaptive pig feeding method is provided, comprising:

[0094] S101: Obtaining pig feeding environment information and weak pig information; the pig feeding environment information includes: water supply temperature and feed remaining amount in the feeding basin.

[0095] S102: Based on the adjusted water-to-material ratio and the material replenishment instruction, material is discharged and water is supplied.

[0096] S103: Based on the input feeding mode, water-to-feed ratio and pig feeding environment information, combined with the temperature compensation algorithm, the water-to-feed ratio is adjusted; and the feeding instruction is obtained based on the weak pig information; the feeding mode includes: dry feed feeding mode, porridge quantitative feeding mode, porridge meal feeding mode, porridge free feeding mode and mixed feeding mode.

[0097] S104: Based on the adjusted water-to-material ratio and the material replenishment instruction, material is discharged and water is supplied.

[0098] Specifically, S103 can be replaced by the following steps:

[0099] The adjusted water-to-material ratio is determined using the formula L = R × (1 ± k × ΔT). For every 1°C change in water temperature, the water-to-material ratio is adjusted using the formula: increase water at high temperatures and reduce water at low temperatures. Where L represents the adjusted water-to-material ratio, R represents the original water-to-material ratio, k represents the adjustment coefficient, and ΔT represents the change in water temperature. ΔT = actual temperature - optimum temperature upper limit (when high) or lower limit (when low). When the temperature is high (ΔT>0): for every 1°C increase, the adjustment coefficient k = 0.05 (water demand increases by 5%); when the temperature is low (ΔT<0): for every 1°C decrease, the adjustment coefficient k = -0.03 (water demand decreases by 3%). The adjusted upper and lower limits of the water-to-material ratio do not exceed the upper and lower limits of the theoretical water-to-material ratio. For example, the optimum temperature during the stable period of nursery is 22-26°C. If the actual temperature is 28°C (ΔT=28-26=2°C), the water-to-material ratio is adjusted to 3.5×(1+0.05×2)=3.75:1.
