Poultry hatching egg gender detection device and system based on ultraviolet light source

Abstract

The invention discloses a poultry hatching egg gender detection device and system based on an ultraviolet light source. The device comprises at least one self-frequency-doubling laser; the self-frequency-doubling laser comprises a pumping source and a light path transmission assembly. The pumping source is used for emitting pumping light; the light path transmission assembly is used for carrying out condensation, gain, filtering and frequency doubling on the pump light and then outputting ultraviolet laser; the system comprises a detection device, an optical fiber, a detection chamber, a spectrograph and a detection terminal, where the detection chamber comprises a beam expanding lens group, a camera obscura, an objective table and a collimating lens group, and the objective table is mounted in the camera obscura; the beam expanding lens group and the collimating lens group are respectively arranged at two ends of the camera obscura; the beam expanding lens group is used for expanding the laser; the collimating lens is used for receiving the ultraviolet laser penetrating through the objective table and outputting the ultraviolet laser to the spectrograph; according to the invention, rich information of the poultry hatching eggs in the 360-380nm ultraviolet band and the spectrum difference characteristic of the male and female hatching eggs are fully utilized, and gender detection of the poultry hatching eggs is achieved.

Description

technical field [0001] The invention relates to the field of laser technology, and more specifically relates to a device and system for detecting the sex of poultry breeding eggs based on an ultraviolet light source. Background technique [0002] The hatching process of poultry eggs consumes energy and time, and the hatched chicks have great differences in economic value due to their sex. Therefore, it is of great significance to determine the sex of poultry eggs as soon as possible for the development of animal husbandry. [0003] The following takes eggs as an example to briefly introduce the current poultry egg fertilization and sex detection technology. [0004] Chickens are the most common poultry. Male chickens cannot lay eggs, and the meat quality is not as good as that of hens. Breeders usually kill or crush male chickens after hatching as feed. If male eggs can be screened out in advance, it can avoid or Stop hatching and sell it for profit to avoid mass killing of...

Problems solved by technology

Even so, currently on the market are only low-brightness, wide-spectrum ordinary light sources, neither penetrating power nor monochromaticity can meet the detection needs, the resolution is low, and the accuracy is poor, so it is urgent to develop a light source that can work in the 360-380nm band. Miniaturized, cost-effective, high-reliability dedicated UV light source
