Description

[0001] This invention relates to livestock feeding devices, specifically to an intelligent feeding self-inspection system and method for lactating sows. Background Technology

[0002] In recent years, large-scale pig farms have faced challenges such as closed management, slow delivery of living supplies, complex disinfection procedures for maintenance personnel, and high turnover of breeding technicians. As a result, there are problems such as difficulty in repairing intelligent feeding equipment and high after-sales costs.

[0003] Although some intelligent feeding devices have been proposed at present, such as the intelligent sow feeding system and control method disclosed in invention application CN103947571A, which is used to feed sows and achieves feeding by controlling the motor to drive the auger, this intelligent sow feeding system has shortcomings. It cannot perform fault self-diagnosis of its own device or early warning of sow diseases. In particular, the key components cannot be replaced modularly when damaged. If equipment failure occurs in large-scale and batch use, it is not easy for ordinary electricians to repair, and there are problems such as difficult after-sales maintenance, which will affect the sow's feed intake and reduce the sow's productivity. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned problems and provide an intelligent feeding self-inspection system and method for lactating sows. This self-inspection system and method can realize self-inspection of faults in key parts, guide pig farm workers to replace faulty parts in a modular manner, reduce the need for maintenance personnel to enter the farm, improve maintenance efficiency, reduce equipment usage costs, and promote cost reduction and efficiency improvement in large-scale pig farms.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A self-checking system for intelligent feeding of lactating sows, comprising a back-end controller and several intelligent feeding terminals;

[0007] The intelligent feeding terminal includes a feeding execution device and a feeding controller; the feeding controller is electrically connected to the feeding execution device and is used to receive the working signals of each execution module of the feeding execution device.

[0008] The background controller includes a central controller and a handheld controller; the central controller is electrically connected to the feeding controller and is used to display the fault self-test results of the feeding execution devices of all intelligent feeding terminals; the handheld controller is connected to the feeding controller via a wireless connection network and is used to query and display the fault self-test results of the feeding execution devices of a single intelligent feeding terminal.

[0009] In a preferred embodiment of the present invention, the central controller is further configured to display the feeding self-test results of the feeding execution devices of all intelligent feeding terminals;

[0010] The handheld controller is also used to query and display the feeding self-test results of the feeding execution device of a single intelligent feeding terminal.

[0011] In a preferred embodiment of the present invention, the feeding controller is provided with a QR code of the same number of digits but different parameters as a device number. The QR code is used for scanning by a handheld controller to realize information interaction between the feeding controller and the handheld controller.

[0012] In a preferred embodiment of the present invention, the feeding controller includes an alarm light.

[0013] A method for intelligent feeding self-checking of lactating sows includes the following steps:

[0014] The feeding operation is performed by the feeding actuator, and the operating signal is sent to the feeding controller through the feeding actuator.

[0015] When the feeding controller receives the working signal from the feeding actuator, it determines that the feeding actuator is working normally; when the feeding controller does not receive the working signal from the feeding actuator or the received working signal is abnormal, it determines that the feeding actuator has malfunctioned, sends a fault signal to the central controller and the handheld controller, and issues a fault signal through the alarm light.

[0016] Staff locate the corresponding feeding actuator based on the fault signals from the central controller, handheld controller, or alarm light, and then repair the feeding actuator.

[0017] In a preferred embodiment of the present invention, the feeding execution device includes a feeding mechanism, and the feeding mechanism includes a pushing drive motor;

[0018] If the feeding controller receives the working current pulse signal of the feeding drive motor, it will monitor that the feeding drive motor is working normally; if the feeding controller does not receive the working current pulse signal of the feeding drive motor, it will diagnose that the feeding drive motor is faulty, and the fault will be displayed on the central controller and handheld controller. The alarm light on the feeding controller will then flash red.

[0019] In a preferred embodiment of the present invention, the feeding actuator includes a water discharge mechanism, which includes a solenoid valve;

[0020] If the feeding controller can receive the working pulse signal of the solenoid valve, the solenoid valve is working normally; if the feeding controller cannot receive the working pulse signal of the solenoid valve, the solenoid valve is diagnosed as faulty, and the fault is displayed on the central controller and handheld controller. The alarm light on the feeding controller will then flash red.

[0021] In a preferred embodiment of the present invention, the feeding actuator includes a water discharge mechanism, which includes a flow meter;

[0022] If the feeding controller can receive the flow meter's working pulse signal, the flow meter is working normally; if the feeding controller cannot receive the flow meter's working pulse signal, the flow meter is diagnosed as faulty, and the flow meter fault is displayed on the central controller and handheld controller. The alarm light on the feeding controller will then flash red.

[0023] Furthermore, when the feeding controller diagnoses a flow meter malfunction, it controls the water flow by setting the operating time of the solenoid valve; the formula for calculating the operating time of the solenoid valve is as follows:

[0024]

[0025] In the formula, T1 is the working time of the solenoid valve; η is the water pressure value of the water pipe; ξ is the number of extensions and retractions of the feed pusher motor; α is the sow parity coefficient, 1≤α≤10; β is the water-feed ratio optimization coefficient, 0<β≤1.

[0026] In a preferred embodiment of the present invention, the feeding execution device includes a touch mechanism, which includes a touch sensor;

[0027] If the feeding controller can receive the working pulse signal from the touch sensor, the touch sensor is working normally; if the feeding controller cannot receive the pulse signal from the touch sensor, the touch sensor is diagnosed as faulty, and the touch sensor fault is displayed on the central controller and handheld controller. The alarm light on the feeding controller will then flash red.

[0028] Furthermore, when a malfunction of the touch sensor is diagnosed, the feeding controller adopts an adaptive feeding method, with a feeding amount F. t It is obtained through the following calculation formula:

[0029] F t =-0.0159r 2 +0.4871r+0.1199, 1≤r≤21;

[0030] Where r is the age of the lactating sow at farrowing.

[0031] In a preferred embodiment of the present invention, a feeding signal is sent to a feeding controller via a feeding execution device. The feeding signal includes a feeding signal, a drinking signal, and a touch count signal.

[0032] Furthermore, if the actual feed intake is less than 50% of the preset feed intake, it is determined to be insufficient feed intake; the central controller and handheld controller will display insufficient feed intake information, and the alarm light on the feeding controller will activate and emit a flashing red light;

[0033] The formula for calculating the preset feed amount F1 is:

[0034] F1 = -0.0227r 2 +0.6958r+0.1713, 1≤r≤21;

[0035] The formula for calculating the actual feed intake F when feed intake is insufficient is:

[0036] F < -0.0114r 2 +0.3479r+0.0857, 1≤r≤21.

[0037] Furthermore, if the actual water intake is less than 50% of the preset water intake, it is determined to be insufficient water intake; the central controller and handheld controller will display insufficient water intake information, and the alarm light on the feeding controller will activate and emit a flashing red light;

[0038] The mathematical model function for the preset water intake W1 is:

[0039] W1 = -0.0722r 2 +2.6826r+2.256, 1≤r≤21;

[0041] W < -0.0361r 2 +1.3413r+1.128, 1≤r≤21.

[0042] Furthermore, if the actual number of touches does not reach the number of touches specified in the preset mathematical model, it is determined that the number of touches is abnormal; the central controller and handheld controller will display that the number of touches by the sow is insufficient, and the alarm light on the feeding controller will activate and emit a flashing red light;

[0043] The mathematical model function for the preset number of touches P1 is:

[0044] P1 = -0.0065r 2 +1.5201r+0.5835, 1≤r≤21;

[0045] The formula for calculating the actual water intake P when the number of touches is insufficient is:

[0046] P < -0.0065r 2 +1.5201r+0.5835, 1≤r≤21.

[0047] Furthermore, when the amount of feed, the amount of water consumed, and the number of triggers are all lower than the warning values ​​set by the mathematical model, an epidemic warning is triggered.

[0063] Figure 4 The flowchart illustrates the process of the intelligent feeding self-inspection system for lactating sows in this invention for performing early warning and self-inspection of sow diseases. Detailed Implementation

[0064] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0065] See Figure 1-2 The intelligent feeding self-checking system for lactating sows in this embodiment includes a backend controller and several intelligent feeding terminals. Each intelligent feeding terminal includes a feeding execution device and a feeding controller 1 (intelligent feeder). The feeding controller 1 is electrically connected to the feeding execution device and receives working signals from each execution module of the feeding execution device. The feeding execution device includes a feeding mechanism, a watering mechanism, and a contact mechanism. The feeding mechanism includes a pusher motor 2 (push rod motor); the watering mechanism includes a solenoid valve 3 and a flow meter 4; and the contact mechanism includes a contact sensor 5. Specifically, the core components such as the pusher motor 2, solenoid valve 3, flow meter 4, and contact sensor 5 all adopt a modular structure, facilitating modular replacement by the farmer.

[0066] The background controller includes a central controller and a handheld controller. The central controller is electrically connected to the feeding controller 1 via a CAN bus. The central controller is used to display the fault self-test results and feeding self-test results of the feeding execution devices of all intelligent feeding terminals. The handheld controller is connected to the feeding controller 1 via a wireless WiFi local area network. The handheld controller is used to query and display the fault self-test results and feeding self-test results of the feeding execution devices of a single intelligent feeding terminal.

[0067] Furthermore, the feeding controller 1 is equipped with a QR code with the same number of digits but different parameters as a device number. This QR code is used by the handheld controller to scan in order to realize information interaction between the feeding controller 1 and the handheld controller.

[0068] The QR code ID number on the feeding controller 1 is used by the fault self-diagnosis system to determine the position of the feeding controller 1.

[0069] Furthermore, the feeding controller 1 is equipped with an alarm light 6.

[0070] See Figure 1-3 The intelligent feeding self-checking method for lactating sows in this embodiment includes the following steps:

[0071] The feeding operation is performed by the feeding actuator, and the operating signal is sent to the feeding controller 1 through the feeding actuator.

[0072] When the feeding controller 1 receives the working signal from the feeding actuator, it determines that the feeding actuator is working normally; when the feeding controller 1 does not receive the working signal from the feeding actuator or the received working signal is abnormal, it determines that the feeding actuator has malfunctioned, sends a fault signal to the central controller and the handheld controller, and issues a fault signal through the alarm light 6.

[0073] Based on the fault signals from the central controller, handheld controller, or alarm light 6, the staff located the corresponding feeding actuator and repaired it.

[0074] See Figure 1-3 If the feeding controller 1 receives the working current pulse signal of the pusher motor 2, it will monitor that the pusher motor 2 is working normally; if the feeding controller 1 does not receive the working current pulse signal of the pusher motor 2, it will diagnose that the pusher motor 2 is faulty, and the fault will be displayed on the central controller and handheld controller. The alarm light 6 on the feeding controller 1 will be activated and emit a flashing red light to remind the feeder to replace the pusher motor 2 modularly.

[0075] After the feeder replaces the feed pusher drive motor 2 modularly, the feed pusher drive motor 2 is checked based on the detected current pulse signal to determine whether it has returned to normal. If it has returned to normal, the feeding mode is restored; otherwise, it is restored.

[0076] See Figure 1-3 If the feeding controller 1 can receive the working pulse signal of the solenoid valve 3, then the solenoid valve 3 is working normally; if the feeding controller 1 cannot receive the working pulse signal of the solenoid valve 3, then the solenoid valve 3 is diagnosed as faulty, and the fault of the solenoid valve 3 is displayed on the central controller and handheld controller. The alarm light 6 on the feeding controller 1 will be activated and emit a flashing red light to remind the feeder to replace the solenoid valve 3 in a modular manner.

[0077] After the feeder replaces solenoid valve 3 modularly, the feeder determines whether solenoid valve 3 has returned to normal based on the detected pulse signal. If it has returned to normal, the feeder returns to the normal feeding mode; otherwise, the feeder returns to the normal mode.

[0078] See Figure 1-3 If the feeding controller 1 can receive the working pulse signal of the flow meter 4, then the flow meter 4 is working normally; if the feeding controller 1 cannot receive the working pulse signal of the flow meter 4, then the flow meter 4 is diagnosed as faulty, and the fault of the flow meter 4 is displayed on the central controller and the handheld controller. The alarm light 6 on the feeding controller 1 will be activated and emit a flashing red light to remind the feeder to replace the flow meter 4 in a modular way. At the same time, the adaptive drinking algorithm will be activated to meet the drinking needs of the sow.

[0079] Furthermore, the main principle of the adaptive drinking water algorithm is as follows: When the feeding controller 1 diagnoses a fault in the flow meter 4, parameters can be set in the central controller based on the number of extensions and retractions of the feed pusher motor 2. This controls the water volume by adjusting the operating time of the solenoid valve 3 for the faulty flow meter 4. If the flow meter 4 is functioning correctly, the Hall pulse signal from the flow meter 4 controls the solenoid valve 3. The formula for calculating the operating time of the solenoid valve 3 is as follows:

[0080]

[0081] In the formula, T1 is the working time of solenoid valve 3; η is the water pressure value of the water pipe; ξ is the number of extensions and retractions of pusher drive motor 2; α is the sow parity coefficient, 1≤α≤10; β is the water-to-feed ratio optimization coefficient, 0<β≤1.

[0082] After the feeder replaces flow meter 4 modularly, the system determines whether flow meter 4 has returned to normal based on the detected Hall pulse signal. If it has returned to normal, the system returns to the normal feeding mode and automatically exits the adaptive drinking water algorithm; otherwise, it does not.

[0083] See Figure 1-3 If the feeding controller 1 can receive the working pulse signal of the touch sensor 5, then the touch sensor 5 is working normally; if the feeding controller 1 cannot receive the pulse signal of the touch sensor 5, then the touch sensor 5 is diagnosed as faulty, and the fault of the touch sensor 5 is displayed on the central controller and the handheld controller. The alarm light 6 on the feeding controller 1 will be activated and emit a flashing red light.

[0084] Furthermore, when a malfunction is diagnosed in the touch sensor 5, the feeding controller 1 adopts an adaptive feeding method, with a feeding amount F. t It is obtained through the following calculation formula:

[0085] F t =-0.0159r 2 +0.4871r+0.1199, 1≤r≤21.

[0086] Where r is the age of the lactating sow at farrowing.

[0087] See Figure 1-2 and Figure 4 The feeding device sends a feeding signal to the feeding controller 1, which includes a feeding signal, a drinking signal, and a touch count signal.

[0088] Furthermore, if the actual feed amount does not reach 50% of the preset feed amount, it is determined to be insufficient feed intake; the central controller and handheld controller will display the insufficient feed intake information, and the alarm light 6 on the feeding controller 1 will activate and emit a flashing red light;

[0089] The formula for calculating the preset feed amount F1 is:

[0090] F1 = -0.0227r 2 +0.6958r+0.1713, 1≤r≤21.

[0091] The formula for calculating the actual feed intake F when feed intake is insufficient is:

[0092] F < -0.0114r 2 +0.3479r+0.0857, 1≤r≤21.

[0093] Furthermore, if the actual water intake is less than 50% of the preset water intake, it is determined to be insufficient water intake; the central controller and handheld controller will display insufficient water intake information, and the alarm light 6 on the feeding controller 1 will activate and emit a flashing red light;

[0094] The mathematical model function for the preset water intake W1 is:

[0095] W1 = -0.0722r 2 +2.6826r+2.256, 1≤r≤21.

[0096] The formula for calculating the actual water intake W when water intake is insufficient is:

[0097] W < -0.0361r 2 +1.3413r+1.128, 1≤r≤21.

[0098] Furthermore, if the actual number of touches does not reach the number of touches in the preset mathematical model, it is determined that the number of touches is abnormal; the central controller and handheld controller will display that the number of touches by the sow is insufficient, and the alarm light 6 on the feeding controller 1 will activate and emit a flashing red light;

[0099] The mathematical model function for the preset number of touches P1 is:

[0100] P1 = -0.0065r 2 +1.5201r+0.5835, 1≤r<21.

[0101] The formula for calculating the actual water intake P when the number of touches is insufficient is:

[0102] P < -0.0065r 2 +1.5201r+0.5835, 1≤r≤21.

[0103] Furthermore, when the amount of feed, the amount of water, and the number of triggers are all lower than the warning values ​​set by the mathematical model, a disease warning is triggered; the central controller and the handheld controller will display the warning information, and the alarm light 6 on the feed controller 1 will activate and emit a flashing red light to remind the feeder to treat the sow.

[0104] Among them, the mathematical model F2 for the early warning feeding amount is:

[0105] F2 = -0.01r 2 +0.3637r-0.1793, 1≤r≤21.

[0106] The mathematical model W2 for early warning water consumption is:

[0107] W2 = -0.0296r 2 +1.4357r-0.235, 1≤r≤21.

[0108] The mathematical model function for the number of warning touches P1 is:

[0109] P1 = -0.0065r 2 +1.5201r +0.5835, 1≤r≤21.
