In this embodiment, the principle of implementing individual identification of pigs by the pig herd individual identification system is as follows:
(1) the central processing system controls the opening and closing states of an outer door and an inner door of the pig growth rounding port channel, so that the pigs are only positioned in the inlet channel; specifically, the outer door is opened, the inner door is closed, so that the pigs only enter the entrance passage, and the outer door is closed after the pigs only enter the entrance passage.
(2) The central processing system controls first image acquisition equipment above the inlet channel to acquire an initial backfat image of the pig in the inlet channel and sends the acquired initial backfat image of the pig to the central processing system; the central processing system determines the position of the back fat of the pig according to the acquired initial back fat image of the pig, controls the spraying device to move to the corresponding position, and sprays corresponding characters on the back fat of the pig, wherein the characters are unique identification characters, namely the characters on each pig body are different.
(3) The central processing system controls the first image acquisition equipment to acquire the pig backfat image sprayed with the characters and sends the pig backfat image to the central processing system, and the central processing system identifies the characters in the backfat image through an image identification technology so as to determine the number of the corresponding pig individual.
(4) The initial weight of the swine only at the beginning of the feeding period is measured by a weight scale disposed below the entrance tunnel, and the measured weight information is transmitted to the central processing system.
(5) The central processing system controls the opening of an inner door of a pig growth rounding port channel, so that pigs only enter a herd pig activity area in a pig growth house; and meanwhile, the second image acquisition equipment is controlled to acquire the pig backfat image of the pig activity region in the pig growth house, the second image acquisition equipment sends the acquired pig backfat image to the central processing system, and the central processing system identifies individual identification characters on the pig backfat image based on the image identification technology to finish individual identification of the group of pigs. In this embodiment, when the pig movement area in the pig growth house is divided into a plurality of sub-areas, and the second image capturing devices are respectively disposed above the sub-areas, the central processing system may determine the movement track of the corresponding pig according to the pig backfat image obtained from each second image capturing device. For example, a group pig activity area in a pig growth house is divided into four sub-areas a1, a2, A3 and a4, second image acquisition devices a1, a2, A3 and a4 are respectively arranged on the four sub-areas, for a pig x, if a backfat image of the pig x sent by the second image acquisition devices A3, a4, a1 and a2 is sequentially received by a central processing system in a certain time period, individual identification characters on a live pig backfat image are identified based on image identification technology, the motion track of the pig x in the time period can be determined to be A3 → a4 → a1 → a2, meanwhile, in each sub-area, through continuous backfat image, individual identification characters on the live pig backfat image identification technology are identified, the continuous motion track of the pig in the sub-area can be determined, and further, continuous monitoring of the motion track and motion quantity of the pig can be realized.

(7) The third image acquisition equipment above the trough channel acquires the pig backfat image entering the trough channel periodically (such as every day) or under the condition triggered by specific conditions and sends the pig backfat image to the central processing system, the central processing system identifies individual identification characters on the live pig backfat image based on the image identification technology to determine the individual pig, meanwhile, the definition of the characters in the pig backfat image is obtained and judged through the image identification technology, under the condition that the definition evaluation value exceeds a threshold value, the central processing system controls the second character spraying device above the trough channel to move to a corresponding position, and the pig is re-sprayed with the corresponding unique characters on the basis of the original characters of the pig backfat. Or the central processing system can perform re-spraying of the unique characters on the pigs regularly, specifically, when the set time is up, the central processing system acquires the pig backfat images entering the trough channel through the third image acquisition device, determines the individual pigs and the unique characters sprayed on the backfat of the individual pigs, and then controls the second character spraying device to re-spray the unique characters on the pigs.
(8) The infrared thermal imager above the trough channel measures the body temperature of the pigs entering the trough positioning channel and transmits the measured body temperature information to the central processing system, a weight scale can be arranged in the trough positioning channel to measure the body weight of the pigs entering the trough positioning channel and transmit the measured body weight information to the central processing system. Meanwhile, the central processing system can determine the individual pigs from which the weight information and the body temperature information come through characters in backfat images acquired by third image acquisition equipment above the trough channel, can acquire the information of the movement tracks, the body temperature, the body weight and the like of the pigs and can monitor the growth character parameters of the pigs in the whole feeding period in real time.
In conclusion, the pig is fixed in the entrance channel through the entrance outer door and the entrance inner door, and after the back fat initial image is acquired through the first image acquisition equipment such as the camera on the entrance channel, the individual recognition characters are automatically sprayed on the back fat of the pig by the first character spraying device; after the pigs enter the pig swarm activity area, second image acquisition equipment such as a camera above the pig swarm activity area acquires individual backfat images of the pigs in real time, and the central processing system identifies individual identification characters on the individual backfat images of the pigs based on an image identification technology, so that individual identification of the pigs and real-time detection of growth character parameters can be further realized; when the pig eats, occupy the place when only the individual feed of pig is fixed through portable silo location fence, realize that the individual discernment character of pig is heavy mark by silo passageway top third image acquisition equipment and second character spraying device, guarantee twice heavy spray time interval in the individual discernment character of live pig clear.
