Embodiment Construction

[0024] In order to make the present invention easier to understand, specific embodiments of the present invention will be further described below.

[0025] Such as Figure 1 to Figure 4 As shown, the present invention provides a system for gender identification and sorting of rats and mice, including a rat sorting slideway 1 made of special materials, a linear array industrial camera 2, a linear array light source 3, a rat pipe 4, and a rat The sorting area 5, the AGV handling robot 6, the cage 7, the driving platform 8, and the rotating mechanism 9, the AGV handling robot 6 transports the cage 7 with the rats and mice to the driving platform 8. The driving platform 8 is used to drive out the rats and mice in the cages on the platform 8, and the experimental mouse classification slideway 1 is connected with the driving platform 8, and is used to slide down the rats and mice and separate them into independent individuals. The linear array industrial camera 2 is located below t...

Abstract

The invention discloses a sex identification and sorting system for rats and mice. The system comprises an expelling platform for expelling the rats and mice in cages on the expelling platform, a laboratory mouse classification slideway connected with the expelling platform and used for sliding the rats and mice downwards and separating the rats and mice into independent individuals, a linear array industrial camera located below the laboratory mouse classification slideway and used for shooting abdominal images of the rats and mice, calling an image processing special algorithm to calculate the distance between genitals and anuses of the rats and mice, and judging the genders and body sizes of the rats and mice according to the distance; and a laboratory mouse pipeline connected with thelaboratory mouse classification slideway and used for feeding the rats and mice with the different genders and sizes into a laboratory mouse sorting area. According to the sex identification and sorting system, sex distinguishing can be conducted on a large batch of sexually mature experimental rats and mice, the rats and mice are sub-packaged in different areas according to different sexes, sex classification of the experimental rats is efficiently and accurately achieved, a large amount of time is saved, and pollution caused by external factors to the rats and mice is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent breeding of experimental animals in a barrier environment, in particular to a gender identification and sorting system for rats and mice. Background technique [0002] Rats and mice are important experimental animals, which play an extremely important role in improving the quality of human life, developing biomedical technology, and promoting social and economic development. Rats and mice used in modern medical research must be kept in a comfortable, stress-free and controlled barrier environment. Rats and mice need to be bred during breeding, but at present the gender identification and sorting of rats is mainly done manually, which is not only inefficient but also easily disturbs the rats and reduces the quality of the raised rats. The automated gender identification and sorting system can not only identify the sex of rats and mice in large quantities, improve efficiency, but also realize u...
