Description

Technical Field

[0001] The invention relates to the technical field of livestock breeding, and in particular to a pig growth monitoring integrated feeder and management system. Background Art

[0002] Livestock farming, especially large-scale pig farming, requires a series of processes to monitor the growth of individual pigs. Among them, the basic data of feed usage and weight gain is used to monitor the growth data changes of individual pig meat. It is necessary to use an integrated feeder to monitor feed usage changes and collect weight data, so as to build an individual pig growth monitoring system, so as to efficiently analyze meat quality growth and adjust feed amount and feeding method.

[0003] After searching, it was found that a piglet weighing device that is convenient for restraint was disclosed in the invention patent with Chinese patent publication number CN116734973A. The piglet weighing device in the invention patent adopts transmission restraint weighing, and restrains the piglets through an adaptive clamping unit and a stabilizing unit, so that the movement amplitude of the piglets is reduced as much as possible during weighing, and the piglets can be comforted at the same time to ensure the weighing accuracy.

[0004] However, the piglet weighing device that is convenient for restraining cannot meet the requirements of weighing and feeding at the same time, and is not convenient for collecting and analyzing the feed-to-meat ratio data of individual pigs. In addition, the bundling method easily causes stress to different individuals, affecting the subsequent feeding of individual pigs. Therefore, the weighing method of the piglet weighing device needs to be further improved. Therefore, an integrated feeder and management system for pig growth monitoring is proposed.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1

[0036] In this embodiment, the feed storage tank is externally connected through the feed pipe 4, and the feed is discharged into the storage trough chamber 201 through the feed inlet. The level sensor 203 is used to detect the change of the material level. The specific working process is as follows:

[0037] 1) The ultrasonic probe of the level sensor 203 emits ultrasonic pulses, and after receiving the surface of the material, the echo is reflected. At this time, the distance is calculated by calculating the round-trip time of the sound wave, that is, the current material level height, which is expressed as:

[0038] Measured distance = (ultrasonic sound speed × time) / 2

[0039] Material level height = total container height - measured distance;

[0040] 2) The interface of the level sensor 203 is connected to the digital input pin of the control panel 6. After the controller module analyzes and processes the input digital signal, based on the preset minimum material level threshold, a high-level signal is triggered and output, and then it is connected to the relay through the digital output pin, and then the warning light 5 is controlled to light up for low material level warning.

[0041] Embodiment 2

[0042] In this embodiment, when the pig enters the channel trough box 102 and the ear tag enters the detection and induction area of the RFID reader / writer 9, the detection and identification process includes:

[0043] 1. The RFID reader 9 reads the ID numbers of different individual pigs stored inside the ear tags, transmits the ID numbers to the controller module for processing through the analog input pins, and the controller module queries and matches the numbered data corresponding to the ID numbers stored in the system database to verify the ID validity;

[0044] 2. If the ID verification is successful, the digital output pin of the controller outputs a level signal to the relay control terminal, and then the relay output terminal is electrically connected to the solenoid valve coil. The solenoid valve is used to control the ventilation direction of the cylinder seat 204, and the spring expands and retracts to reset, realizing the movement switch effect of the pneumatic push rod and the baffle 205. The opening time of the baffle 205 is controlled by the time relay to control the feeding amount;

[0045] The feeder reads the pig ear tag through the RFID reader, thereby determining the identity of the pig, and then reads the food intake threshold in the system. At this time, the baffle 205 opens the feeding port at the bottom of the storage tank chamber 201 to feed the feed. If the food intake of the pig individual on the same day has reached the threshold, no feeding will occur when the pig enters the feeder;

[0046] And through the pressure spring plate 10 inside the feed trough and the piezoelectric induction end of the pressure sensor 207, the weight change of the spring plate 10 is detected to determine whether there is residual feed and the residual amount inside the trough. If it is determined that there is residual material inside the trough, the feed feeding amount needs to include the residual amount inside the trough;

[0047] When the pig enters the trough in the feed trough chamber 202, its head will cut off the light beam path between the two opposed photoelectric switches 206. At this time, the light signals received by the two opposed photoelectric switches 206 decrease or even no signal is received, determining that the pig is in the process of eating. When the pig is in the eating state, the solenoid valve controls the cylinder seat 204 not to feed to avoid errors in the food intake record.

[0048] Embodiment III

[0049] In this embodiment, an elastic body material with a resistance strain gauge pasted on it is arranged inside the tension sensor 302. The internal elastic body is elongated by pulling the lower pull spring ring 11. The detection process is as follows:

[0050] When the pig enters the passage trough box 102 to eat, it steps on the weighing plate 307 steadily. At this time, the weighing plate 307 drives the suspension rod 306 to sink according to the individual weight of the pig. The rack 3081 of the suspension rod 306 pushes the transmission gear 3082 to rotate. The transmission gear 3082 meshes with the rack 3081 of the second connecting rod 3042, driving it to move upward, and driving one end of the first connecting rod 3041 to lift. The other end connected to the lifting rod 303 descends, causing the lifting rod 303 to pull down the spring ring 11 of the tension sensor 302. The spring ring 11 drives the elastic body to elongate, causing the resistance strain gauge to deform and generate an electrical signal. The tension data is measured based on this electrical signal, thereby detecting the pig's body weight.

[0051] Embodiment 4

[0052] In this embodiment, the ear tag contains a three-axis acceleration sensor. Through the ear tag, the identity information and activity information of individual pigs can be collected. The data analysis module of the system collects 600 pieces of one-minute body weight data, removes the two hundred pieces of data at the head and tail, sums and averages the remaining two hundred pieces of data, and uses it as the real body weight data of the pig. Furthermore, the feed-to-meat ratio data is calculated based on the feed feeding amount, and the growth status of the pig is evaluated and classified through the feed-to-meat ratio and activity to analyze the growth status of the pig.

[0053] To sum up, for the integrated feeding device and management system for pig growth monitoring, after putting the pig into the passage trough box 102, the RFID reader 9 detects and identifies the specific ear tag information of different individual pigs. According to the growth status and slaughter weight threshold of individual pigs, the control system sets the feed intake threshold for each pig. The RFID reader reads the feed intake threshold in the system, adjusts the cylinder seat 204 to control the opening time of the baffle 205, and feeds a fixed amount of feed below, facilitating the weight detection of the pig in a stable feeding state and avoiding the situation of pig stress behavior caused by traditional restraint methods;

[0054] When the pig steps on the weighing plate 307 steadily during eating, the weighing plate 307 drives the suspension rod 306 to sink according to the individual weight of the pig. At this time, the rack 3081 of the suspension rod 306 pushes the transmission gear 3082 to rotate. Based on the gear meshing principle, the second connecting rod 3042 will be driven by the rack 3081 to move upward, and drive one end of the first connecting rod 3041 connected to the lifting rod 303 to descend, causing the lifting rod 303 to pull down the spring ring 11 of the tension sensor 302, and then measuring the tension data, thereby detecting the pig body weight data.

[0055] After the pig's eating is in a relatively stable state, 600 pieces of one-minute body weight data are collected, the two hundred pieces of data at the head and tail are removed, and the remaining two hundred pieces of data are summed and averaged as the real body weight of the pig. Furthermore, the feed-to-meat ratio data is calculated based on the feed feeding amount to analyze the growth status of the pig.
