Description
Technical Field
The invention belongs to the technical field of automatic mechanical equipment, and particularly relates to a device and a method for detecting the activity of an egg embryo.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
At present, the hatching egg processing of a chicken hatchery has realized automatic and intelligent recognition, but for a duck hatchery, due to the particularity of relatively large hatching eggs such as duck hatching eggs, the duck hatchery still adopts a handheld egg candler to photograph eggs in a hatching tray to recognize the growth condition of hatching egg embryos, the technology is laggard, and the manual operation is complicated.
The hand-held egg candler is internally provided with a common halogen lamp or an LED lamp, the egg candler is irradiated towards the big end of a poultry egg in a dark space at a zero distance, the quality and the speed of the development of the duck egg embryo are manually determined according to the observed situation inside the egg, the egg candling speed is low, only one egg can be candled each time, and time and labor are wasted.
The prior art provides hatching egg automatic identification and letter sorting equipment, and the hatching egg is detected by laser to judge this kind of hatching egg type by the treater and be living embryo, nos smart egg and dead embryo egg, it is fine to the recognition effect of chicken hatching egg, but the general individual of great hatching eggs such as duck hatching egg is big, and the eggshell is thick, and this equipment is unsatisfactory to the differentiation of great hatching egg.
Disclosure of Invention
In view of the above problems in the prior art, it is an object of the present invention to provide an apparatus and a method for detecting the activity of an embryo of an egg. The automatic identification device is used for solving the defects that the hatching egg identification technology in the prior art is manually operated and the technology is laggard, and realizes the automatic identification of the live embryos and the non-live embryos of the hatching egg embryos through the automatic identification device of the hatching egg embryos.
In order to solve the technical problems, the technical scheme of the invention is as follows:
in a first aspect, an apparatus for egg embryo viability detection, comprising:
a point light source structure including a single or a plurality of point light sources, vertically arranged;
the moving structure is connected with the top of the point light source and can enable the point light source to move longitudinally;
the camera shooting structure is arranged on one side or two sides of the point light source structure;
the area light source structure is a plate-type area light source and is provided with a through hole, the camera shooting structure is positioned above the plate-type area light source and is opposite to the through hole, the camera shooting structure is obliquely arranged, and the camera shooting port of the camera shooting structure is opposite to the lower part of the point light source.
The plate-type surface light source is utilized to perform surface light polishing on the hatching eggs, the appearance of the hatching eggs is photographed, the point light source abuts against the hatching eggs and is lightened, the camera shooting structure judges the appearance of the hatching eggs and the picture inside the duck eggs through the through holes, the active state of the hatching eggs is judged through the appearance picture and the picture inside the hatching eggs, and the hatching eggs are judged to be live embryos or non-live embryos. The structure of making a video recording is located the both sides of pointolite, and after the pointolite withstood the hatching egg downwards, the structure of making a video recording was shot from both sides, obtains the picture of both sides, and the vascular condition of observation both sides that can be careful, the three-dimensional shape of blastoderm etc..
Through the cooperation of the movable structure and the point light source structure, the point light source descends and props against the hatching egg, and the internal image of the hatching egg is lightened. Utilize the pointolite to cooperate with mobile structure, withstand the hatching egg and shine the inside condition of hatching egg, obtain the photo, solved because the hatching egg individuals such as duck egg is big, the eggshell is thick leads to the unable embryonal activity's of detecting duck egg of laser problem.
Use the pointolite structure, can realize corresponding every kind of hatching egg, a pointolite descends and withstands the hatching egg, realizes inside lighting, if use great light source, the gathering nature of light source is not good, can disturb the shining of other eggs moreover.
The plate-type surface light source is provided with the through hole, the camera shooting structure can shoot through the through hole, and the influence of the surface light source on the shooting of the camera shooting structure is avoided.
The camera shooting structure and the dough light source are arranged on two sides, and the conditions of two sides of the hatching eggs can be shot respectively.
The invention realizes the identification of the live embryo or the non-live embryo of each hatching egg by the cooperation of the point light source, the surface light source and the camera shooting structure. The conventional method only places all duck eggs into a light chamber to photograph from the top, and only can see the transparent state to judge whether the duck eggs are fertilized eggs or non-fertilized eggs, so that the embryo activity of the duck eggs cannot be judged, and the condition of each duck egg cannot be carefully observed and obtained.
In a second aspect, the method for detecting the activity of the hatching egg embryo comprises the following specific steps:
the hatching eggs transversely move on the conveyor belt, when the hatching eggs reach the detection position, the transverse movement is stopped, the surface light source is lightened, and shells of the hatching eggs are photographed;
the moving structure controls the point light source to move downwards to abut against the hatching egg, so that the inside of the hatching egg is illuminated and a picture is taken.
The egg external images can be divided into broken eggs and eggs with no broken appearance, and the internal images can be judged as live embryos or non-live embryos.
One or more technical schemes of the invention have the following beneficial effects:
the existing method for irradiating the eggshells simply and manually has the advantages that the speed is low, observation of a plurality of eggshells is easy to confuse, irradiation of the eggshells is unstable, contact points of an egg irradiating lamp and hatching eggs are easy to slide and cause instability, if the whole tray of hatching eggs is observed, the plurality of hatching eggs can interfere with each other and easily block the sight, and other hatching eggs can shield external light to influence the observation of the appearance. The device and the method for detecting the embryo activity of the hatching egg can realize the embryo activity identification of each hatching egg in the egg tray, have small interference, and have stable contact position points of the point light source and the hatching egg through the matching of the moving structure and the point light source.
Through the position setting of structure and pointolite, area source of making a video recording, can conveniently gather the condition of the hatching egg in every egg tray, pointolite, area source form one and illuminate the region, improve the picture that the side that the definition can follow the hatching egg obtained the hatching egg, the condition of convenient analysis hatching egg.
Through the structure of making a video recording, can master the picture, then carry out the resolution of every hatching egg, convenient memory and storage moreover.
