DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] For the identification of chick gender, the existing manual operation method has the problems of high labor intensity and low efficiency, and the industrialized identification method has the problems of unsatisfactory identification results, which easily leads to injury or death of the chicks. The present application realizes the non-damaging online detection and sorting of the gender of chicks by designing a flexible conveying belt clamping conveying structure and a chick profiled feather lifting plate.

[0026] The present application detects the genetic characteristics of fast and slow feathers. The chicks with the genetic characteristics of fast and slow feathers have different lengths of main wing feathers and over main wing feathers when hatched. The main wing feathers of hens are longer than the over main wing feathers, and the main wing feathers of roosters are equal to the over main wing feathers. By comparing the length difference of the feathers of the hatched chicks, the gender of the chicks can be represented, and this method can avoid causing damage to the chicks. The present application will be described below in combination with Figures 1-6The application discloses an automatic chick gender detection system and method. Figure 1 is a structural schematic diagram of the automatic chick gender detection system provided by the application, as Figure 1 indicated, the application provides an automatic chick gender detection system, which comprises:

[0027] a main conveying belt 1, a feeding mechanism 2, a clamping mechanism 3, a feather lifting mechanism 4 and a detection device 5; the feeding mechanism 2 is used for enabling a single chick to pass through and then enter the clamping mechanism 3; the clamping mechanism 3 comprises two flexible conveying belts 37 which are consistent with the height of the head of the chick, are horizontally distributed and are arranged in parallel in the main body part; the two flexible conveying belts 37 have gradually narrowing opening parts which are connected with the feeding mechanism 2 in conveying; the feather lifting mechanism 4 is fixed below the middle of the two flexible conveying belts 37 through the two sides of the main conveying belt, the front end of the feather lifting mechanism 4 is shaped according to the contour of the front torso of the chick and the top of the front end is lower than the height of the wing joint, and the front end is smoothly transitioned from the nearly vertical contour curve to the horizontal plane which is consistent with the top height, so as to form a gradually transitioned curved surface, and the middle is hollowed out for the chick to pass through under the clamping of the flexible conveying belt 37; the detection device 5 obtains the image of the chick after passing through the feather lifting mechanism through the camera 6 arranged above the feather lifting mechanism, and inputs the image into the trained gender detection model to output the gender detection result of the chick.

[0028] The gender detection model is a model based on a target detection network, and is obtained by training the image of the chick after passing through the feather lifting mechanism as input and the corresponding gender as label.

[0029] Firstly, the chick is placed to the front end of the main conveying belt 1 of the detection system, and the chick is conveyed backward gradually under the pushing of the conveying main conveying belt, reaches the feeding mechanism 2, and the feeding mechanism 2 enables the single chick to pass through and then enter the clamping mechanism 3. The clamping mechanism 3 comprises two flexible conveying belts 37, and the two flexible conveying belts 37 have gradually narrowing opening parts which are connected with the feeding mechanism 2 in conveying, so that after the single chick passes through the feeding mechanism, the chick can enter the clamping conveying belt formed by the two flexible conveying belts 37 directly through the opening parts of the two flexible conveying belts 37, and the flexible conveying belt 37 is consistent with the height of the head of the chick, so that the head of the chick can be clamped directly, which can not only cause no damage to the body of the chick, but also facilitate the conveying through the feather lifting mechanism 4.

[0030] The running speed of the flexible conveying belt 37 in the clamping mechanism 2 can be set to be consistent with the main conveying belt 1 below, so that the speed of the whole torso of the chick is kept consistent, and the chick cannot appear excessive stress reaction, and the function of dynamic clamping is realized.

[0031] With the conveying of the flexible conveying belt 31, the chick passes through the feather lifting mechanism 4. As shown inFigure 2 As shown, since the shape of the front end of the wing lifting mechanism 4 is profiled on the front body contour of the chick and the top height of the front end is lower than the height of the wing joint, the primary wing feathers and the over primary wing feathers of the chick can be lifted up, and the wing lifting mechanism 4 is smoothly transitioned from the nearly vertical profile curve to the gradually transitioned curved surface consistent with the top height, so that the wing feathers can be smoothly unfolded horizontally to obtain the feather characteristics.

[0032] In addition, the middle of the wing lifting mechanism 4 is designed to be hollow, so that the wing lifting mechanism 4 is divided into two parts and can be fixed on both sides of the main conveying belt 1. The hollow design can make the chick smoothly pass through under the clamping of the flexible conveying belt 37, so as to prevent the chick from being stuck when passing through the wing lifting mechanism 4. After the wing feathers of the chick are unfolded, the camera 6 arranged directly above the wing lifting mechanism 4 obtains the target image of the chick after passing through the wing lifting mechanism 4 and sends it to the detection device 5.

[0033] The detection device 5 stores a trained gender detection model, which can detect the target image to determine the gender of the chick. Specifically, the primary wing feathers and the over primary wing feathers with gender characteristics can be identified and saved in the upper computer based on the target image, and then input into the trained classification network model, i.e. the above-mentioned gender detection model, to classify and identify the gender of the chick.

[0034] Of course, the detection device 5 can also send the target image to a remote server with a trained gender detection model, and wait for the detection result from the server.

[0035] After obtaining the gender detection result, it can be displayed through a display for manual screening. Of course, a sorting device can also be used to automatically classify the chicks with detection results. Thus, the present application realizes the rapid and non-destructive classification of chicks.

[0036] The automatic chick gender detection system of the present application can accurately fix the head of the chick through the flexible conveying belt with a narrow opening as a clamping conveying structure, solve the problem of abnormal movement of the chick due to stress reaction, and realize the automatic and non-destructive gender sorting through the chick-shaped wing lifting mechanism, the trained gender detection model based on the characteristics of the primary wing feathers and the over primary wing feathers of the chick, and the trained gender detection model. It can be effectively applied to actual gender sorting work, reduce labor, and improve sorting efficiency and sorting accuracy.

[0037] In one embodiment, the feeding mechanism 2 comprises a limiting baffle 21 arranged at the entrance of the main conveying belt 1; the limiting baffle 21 is fixed on both sides of the main conveying belt 1 and the passage in the conveying direction of the main conveying belt 1 is narrowed, and the outlet at the narrowest part allows a single chick to pass through.

[0038] As shown in Figure 3 Fig. 2, the width of the outlet of the limiting baffle 21 is slightly larger than the limb width of the chick when it stands upright, which ensures that the chicks can enter the next conveying stage one by one. Under the action of the limiting baffle, the chicks can only pass through one by one when entering the clamping mechanism stage on the conveying main conveying belt.

[0039] Optionally, the feeding mechanism further comprises a connecting rod 22 and an air cylinder 23; the connecting rod 22 adjusts the width of the outlet of the limiting baffle under the action of the air cylinder 23.

[0040] The chick gender automatic detection system of the embodiment of the present application realizes the loose conveying of the chicks through the passage-narrowing limiting baffle, and effectively prevents the chicks from moving abnormally during transportation.

[0041] In one embodiment, the clamping mechanism 3 further comprises a belt motor 31, a motor bracket 32, a shaft 33, a bearing 34, a bearing bracket 35 and a belt pulley 36; the belt motor 31 and the bearing bracket 35 are fixedly installed on both sides of the main conveying belt 1, a plurality of shafts 33 are rotatably installed in the bearing bracket 45 through the bearings 34; a plurality of belt pulleys 36 are installed on the belt motor 31 and the bearing 33, the belt pulley 36 on the belt motor 31 is driven to rotate by the belt motor 31; the flexible conveying belt 37 is in rolling connection with all the belt pulleys 36 and is driven to convey by the belt pulley 36 on the belt motor 31. For details, please refer to Figure 4 , which will not be repeated here.

[0042] In one embodiment, the system further comprises a first sorting mechanism 7, which comprises a sliding table 71, a first motor 72, a first paddle 73 and a classification collection box 74; the sliding table 71 is fixed at the rear end of the main conveying belt 1 and connected with the classification collection box 74; the classification collection box 74 is separated by a partition plate in the middle, dividing the collection area into two parts; the rotating shaft of the first paddle 73 is arranged at the entrance of the classification collection box at the terminal end of the sliding table, and rotates under the control of the first motor 72 to selectively shield the two collection areas; the first motor 72 is controlled by the detection device 5 to drive the two rotating states of the first paddle 72 according to the gender detection result. For details, please refer to Figure 5 , which will not be repeated here.

[0043] In one embodiment, a second sorting mechanism and a second conveying belt are further included; the second sorting mechanism includes a second push plate and a second motor driving the second push plate to rotate, and the second push plate is arranged behind the end of the flexible conveying belt; the detection device, after obtaining the image of the chick after passing through the feather lifting mechanism, is further configured to input the image into the trained feather lifting detection model to output a feather lifting result; in the case that the feather lifting result is failure, the second motor is controlled by the detection device to drive the second push plate to guide the chick failing in feather lifting into the second conveying belt, and the second conveying belt conveys the chick failing in feather lifting to the entrance of the main conveying belt; wherein the feather lifting detection model is trained according to the images of successful feather lifting and the images of failed feather lifting as input, and the corresponding success or failure as label.

[0044] Considering that the chick fails to be successfully lifted by the feather lifting mechanism due to body posture or movement, etc., the present application further uses the feather lifting detection model to judge whether the feather lifting is successful, and in the case that the feather lifting result is failure, the second push plate is used to guide the chick failing in feather lifting into the second conveying belt, and the second conveying belt is used to convey the chick failing in feather lifting to the entrance of the main conveying belt for re-gender sorting. In addition, in the case that the first sorting mechanism is provided, the second push plate can be arranged at the front end of the first push plate.

[0045] The feather lifting detection model can be a separate classification model, or can be the same model as the gender detection model. When the gender detection model and the feather lifting detection model are the same model, the detection model is a three-classification model, i.e., the three types of samples of the female chick successfully lifted, the male chick successfully lifted and the chick failing in feather lifting are used for training, and the model capable of simultaneously detecting gender and feather lifting is obtained after training, for example, the male chick is output as 0, the female chick is output as 1, which indicates that the feather lifting is successful, and the output of 2 indicates that the feather lifting is failed.

[0046] For example, when the gender detection model outputs 2, the second push plate is opened to guide the chick into the second conveying belt and return to the entrance of the main conveying belt 1 for re-detection. When the gender detection model outputs 0 or 1, the first push plate 73 controls the chick to slide to two different collection spaces of the classification collection box 74, respectively.

[0047] In one specific embodiment, the detection device can be realized by the host computer and the lower computer. First, the host computer and the lower computer are initialized, the main conveying belt, the flexible conveying belt clamping conveying mechanism and the sorting mechanism are started, and the chick gender sorting system starts to work. The chick is placed at the front end of the main conveying belt to start moving forward, and is fed into the detection one by one in the positive direction through the feeding mechanism.

[0048] The clamping mechanism clamps the head of the chick by a flexible conveying belt and continues to forwardly convey through the feather lifting mechanism, and the feather lifting plate of the feather lifting mechanism spreads the wings of the chick, so that the primary wing feather and the part of the over primary wing feather are exposed.

[0049] The host computer captures images collected by the analysis camera in real time, a target detection network identifies a framed part, writes the framed part into a folder, and imports the images into a classification network, so as to obtain a gender sorting result. On the host computer, the following functions can be realized: displaying a current picture and a classification result, and sending the result to the lower computer through a serial port program to perform a queue waiting operation.

[0050] The host computer sends a classification prediction result to the lower computer in the form of digital 0 and 1 through a serial port, and allocates memory in the serial port of the lower computer to queue 0 and 1 characters. When the infrared detection module of the actuator of the lower computer senses a chick, the lower computer first reads the first character in the serial port queue, and decides the action of the first dial plate according to the type. The above operation is repeated in a cycle, so that the gender sorting task of the chick is completed in a short time.

[0051] In the present application, in view of the problems of high labor intensity and low efficiency in manual identification of male and female chicks, based on the characteristics of the fast and slow feathers of chicks, by designing a head clamping mechanism and a chick feather lifting plate on the main conveying belt, the fast and slow feather images of the chicks are obtained in the conveying process while ensuring that the chicks are not damaged; by designing a passage contraction mechanism and a cylinder driven clamping feeding mechanism, the function of orderly queuing and feeding of the chicks one by one in the forward direction is realized; by designing control elements and execution elements, the needs of speed and accuracy of the sorting mechanism are met, and the whole process automation of chick feeding, non-destructive gender detection, conveying and sorting is realized.

[0055] The gender detection model is a model based on a target detection network, and the image of the chick after passing through the feather lifting mechanism is taken as input, and the corresponding gender is taken as a label to obtain after training.

[0058] 602. Input each training sample into the constructed object detection network-based model and train it using the known gender as the label;

[0059] 603. Repeat the training process until a model that meets the preset requirements is obtained, and use it as the gender detection model.
