Description

Technical Field

[0001] The present invention relates to the field of agricultural product detection, and in particular to a chick sex detection system. Background Art

[0002] Poultry meat and eggs are playing an increasingly important role in the resident diet, with chickens accounting for a significant portion of poultry consumption. In broiler production, male chicks with higher feed conversion rates and faster growth are desirable, while in laying hen production, more female chicks are desired to increase egg production. Female chicks generally lay eggs earlier, produce more eggs, and consume less feed, while male chicks can be sold as high-quality chickens after reaching adulthood. Therefore, sex sorting of day-old chicks and refined management based on gender differences can effectively improve farming efficiency and economic viability. Therefore, sex sorting and detection methods for day-old chicks are urgently needed and of great significance. Traditional chick sex detection methods mainly include the vent rotation method and molecular biology methods. The vent rotation method for identifying the sex of chicks requires high technical requirements and can cause irritation and damage to the chicks. In actual operation, it is not only labor-intensive, but the identification results are often affected by the subjective bias of the operator.

[0003] With the continuous advancement of poultry breeding technology, sex identification using the sex-linked genetic trait of fast and slow feathering in chicks has become widely used. This method distinguishes chicks of different sexes by observing phenotypic differences in feather growth rate. Compared with the traditional ventral rotation method, this method effectively avoids tissue damage caused by manipulation and misjudgment due to visual fatigue. With its advantages of ease of use and high detection efficiency, the feather speed identification method significantly reduces stress reactions in chicks.

[0004] However, the current chick sex detection method based on machine vision and automated control technology has low identification accuracy and operation automation level. Summary of the Invention

[0007] A chick sex detection system provided according to the present invention further includes a sorting mechanism, which includes an air blowing device arranged at the end of the second conveyor belt, and the air blowing device performs air blowing sorting on the chick samples according to the detection results of the detection unit.

[0008] According to a chick gender detection system provided by the present invention, the processing module is specifically used to: input each first image into a trained gender detection model, and output the gender detection result of each first image; input each second image into the trained gender detection model, and output the gender detection result of each second image; determine the comprehensive gender detection result based on the ratio of the total number of female or male images detected in the first image and the second image as a whole to the total number of detected gender images; wherein the gender detection result includes female and male, and the gender detection model is obtained after training based on sample images of chicks with marked gender unfolding fast and slow feathers.

Finally, the gender determination is output based on the ratio of the recognition results, reducing gender misjudgments caused by motion blur and thus improving detection accuracy. Given that different chick breeds have different sensitivities to tilt, the present invention adjusts the tilt based on the detection results of the second image triggered by the pneumatic nozzle, thereby more accurately determining the tilt angle of the first conveyor belt and improving detection accuracy.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Among them, the first, second, etc. mentioned below are only used to distinguish the same type of features, and are not a limitation on the order or position relationship.

[0018] To address the current challenges of automated sexing for day-old chicks, including low accuracy and the high risk of tissue damage caused by manual operation, this paper provides a fully automated sexing system for day-old chicks. This system leverages the physiological responses and feathering characteristics of chicks, incorporating image recognition technology and deep learning algorithms to enable rapid, non-destructive sexing of early-stage chicks, such as day-old chicks. This system aims to improve detection efficiency and accuracy, reduce reliance on manual operation, and minimize stress and damage to chicks.

[0019] The following combination Figure 1-Figure 5 The chick sex detection system of the present invention is described. Figure 1 Schematic diagram of the chick sex detection system provided by the present invention. Figure 1 As shown, the present invention provides a chick sex detection system, comprising: a feeding mechanism, a collecting mechanism, an angle adjustment rod and a detection unit; the chick sample to be detected is transmitted through the feeding mechanism, a first conveyor belt 21 and a second conveyor belt 22; the collecting mechanism comprises a first camera 24 and a first light source 25 arranged in a first dark box 23, and a second camera, a second light source and a pneumatic nozzle arranged in the second dark box, the first conveyor belt 21 passes through the first dark box 23, the feeding mechanism is horizontally transmitted to the first conveyor belt 21, the first conveyor belt 21 is an inclined conveyor belt, and the second conveyor belt 22 is a horizontal conveyor belt, and the pneumatic nozzle emits an airflow towards the chick sample when the chick sample passes through the second conveyor belt and the second dark box; the detection unit comprises: an acquisition module for acquiring the chick sample through the first camera when the chick sample passes through the first dark box. A first sequence comprising a plurality of first images, and a second sequence comprising a plurality of second images obtained by a second camera when a chick sample passes through a second dark box; a correction module for continuously obtaining the sex detection results of the first sequence and the second sequence of the multiple test chick samples before detection, and adjusting the inclination angle of the first conveyor belt by the angle adjustment rod until the sex detection results of the first sequence of the multiple test chick samples in a preset proportion are consistent with the sex detection results of the second sequence; a processing module for determining the sex detection results of the first sequence according to the proportion of the sex detected in the first sequence of the test chick samples, determining the sex detection results of the second sequence according to the proportion of the sex detected in the second sequence, and determining the sex detection results of the chicks to be detected according to the overall proportion of the sex detected in the first sequence and the second sequence of the chick samples to be detected.

[0020] As shown in the figure, the first conveyor belt 21 can be driven by a first motor 20, and the second conveyor belt 22 can be driven by a second motor 28. The system features a downward-sloping conveyor belt, namely the first conveyor belt 21. On the first conveyor belt 21, chicks passing over the slope from the horizontal loading mechanism will briefly lose their balance due to the gradient change. As a stress response, they instinctively spread their wings. A first camera 24, located above the conveyor belt and within a darkroom, captures images of this gesture in real time. The main control unit captures multiple images from the video stream captured by the first camera 24 as the primary image for subsequent sex detection. The chick sample is then transported along the first conveyor belt to the second conveyor belt.

[0021] To prevent interference from external ambient light, the first camera 24 and subsequent second camera, along with the corresponding detection area, are enclosed within a darkroom. An industrial light source (corresponding to the first and second light sources) is installed within the darkroom to provide supplemental illumination for the chicks, ensuring stable and reliable imaging quality. Considering that some chicks may be insensitive to the sudden gradient of the first conveyor belt 21, this may result in an inability to fully or even unfurl their wings to display the fast and slow feathers, leading to misjudgment. The present invention specifically incorporates a second darkroom 26 after the inclined first conveyor belt 21 transfers to the horizontal second conveyor belt 22. An internal pneumatic nozzle within the darkroom emits airflow toward the chick sample, stimulating a stress response in the chick, causing it to open its wings and display the fast and slow feathers. At this point, the second camera captures a second sequence of multiple second images, which are combined with the first sequence of first images for sex detection. Ultimately, the chick's sex is determined based on the combined test results from the multiple first and second images.

[0022] For the chick samples to be tested, the detection unit can select multiple frames from the video stream taken by the first camera, and select the same multiple frames of images from the video stream taken by the second camera, such as 5 frames of clear images each, to form an image sequence containing 10 frames of images (first image and second image). Subsequently, the image sequence will be input into the deployed target detection model to perform gender recognition analysis on the fast feather and slow feather features revealed when the chicks spread their wings, and comprehensively determine their gender based on the recognition ratio, and output the final detection result. For example, if the sequence is 10 images and the proportion of male chicks is strictly greater than 50%, the gender detection result is male chicks. The detection result corresponding to the image sequence is the detection sequence, as shown in Table 1. The detection results of the images can be referred to. Figure 2 (Female means female chick, male means male chick).

[0023] Table 1

[0024] In addition, the first conveyor belt 21 is an angle-adjustable conveyor belt connected to the chassis by an angle adjustment rod 27, which controls the slope angle. Before testing, the accuracy of the angle adjustment is determined by using multiple test chick samples. For example, the gender test results of the first sequence and the second sequence of 10 test chick samples are continuously obtained. If the gender test results of the first sequence and the second sequence of 8 test chick samples are consistent, the angle adjustment is terminated and the gender test of the chick sample to be tested is performed.

[0025] The chick gender detection system of the present invention differs from existing detection methods that rely on mechanically forcing the chick to spread its wings. It employs a behavioral induction method based on stress response. By providing a conveyor belt structure with a certain tilt angle, the chick is temporarily weightless, stimulating its instinctive response to spread its wings to maintain balance. By creating a temporary weightless state for the chick and stimulating its internal behavioral response to maintain balance, combined with external airflow stimulation, the chick's fast and slow feather characteristics can be more comprehensively displayed, thereby improving detection accuracy. Furthermore, a gender detection sequence is constructed by capturing multiple frames of images, and the chick's wing-spreading behavior is distinguished based on the prominent features in the image. Finally, the gender determination is output based on the ratio of the recognition results, reducing misjudgments caused by motion blur and thus improving detection accuracy. Given that different chick breeds have different sensitivities to tilt, the present invention adjusts the tilt based on the detection results of the second image triggered by the pneumatic nozzle. This allows the first conveyor belt's tilt angle to be adjusted to a reasonable range, preventing a small number of chicks from losing balance due to insufficient tilt stimulation or excessive tilt angle, resulting in inaccurate detection results. Using a preset proportion of multiple test chick samples as a benchmark can filter out the contrast effect caused by a small number of chicks that are insensitive to air blowing stimulation, thereby improving the reliability of angle adjustment.

[0026] In some embodiments, a sorting mechanism is further included, which includes an air blowing device 29 arranged at the end of the second conveyor belt 22. The air blowing device 29 blows and sorts the chick samples according to the detection results of the detection unit. A fifth baffle 30 is provided at both ends of the sorting mechanism 29.

[0027] For example, at the end of the second conveyor belt 22, two air blowing devices 29 are installed in each channel, with airflow controlled by solenoid valves. Based on the real-time sex detection signal transmitted by the detection unit, the system triggers the corresponding nozzle to spray air. Using non-contact pneumatic guidance, the chicks are separated into male and female channels and transported to the corresponding storage bins for sorting. This system automates the entire chick sexing and sorting process, significantly improving sex sorting efficiency and reducing manual labor.

[0028] In some embodiments, the processing module is specifically configured to: input each first image into a trained gender detection model and output a gender detection result for each first image; input each second image into the trained gender detection model and output a gender detection result for each second image; and determine a comprehensive gender detection result based on the total number of images detected as female or male in the first and second images as a whole and the ratio thereof to the total number of images with detected gender; The gender detection results include female and male. The gender detection model is trained using sample images of sex-labeled chicks showing fast and slow feathers. For example, if five first images and five second images are selected and strictly more than half of the images are detected as male, the gender detection result is male.

[0029] In some embodiments, the loading mechanism includes a loading module and an arranging module; the loading module includes a third conveyor belt 12 driven by a motor, and a third baffle 13 on both sides of the third conveyor belt 12; the arranging module includes multiple parallel fourth conveyor belts 17, and a V-shaped diverter plate is provided between two adjacent fourth conveyor belts 17, and the outlet of the fourth conveyor belt 17 is connected to the inlet of the first conveyor belt 21.

[0030] like Figure 3-Figure 5 As shown, the loading module can adopt a wide conveyor belt structure to achieve efficient batch feeding. It is equipped with a third frame 10, and the conveyor belt is driven by a third motor 11 to ensure the smoothness and controllability of the transmission. It is equipped with third baffles 13 on both sides to limit the lateral movement of the chicks during transportation, prevent the chicks from falling due to jumping or sliding, and improve the safety and stability of the system operation. The entire row of modules is equipped with a fourth frame 19, with fourth baffles 16 on both sides. It is designed with multiple conveyor belts in parallel. The width of each conveyor belt is slightly larger than the width of the chicks. The chicks are arranged individually and the conveyor belts are connected and diverted by inverted V-groove guide plates, which effectively solves the problems of accumulation and congestion. The fourth conveyor belt 17 is driven by a fourth motor 15.

[0031] First, the chicks are placed in the loading module and transported via the wide conveyor belt (third conveyor belt 12) to the fourth conveyor belt 17 of the alignment module. A V-shaped diverter plate installed at the connection between two adjacent fourth conveyor belts 17 divides the tightly packed chicks and arranges them into a single file, which then enters the narrow conveyor belt in turn.

[0032] In some embodiments, the width of the row module is greater than the width of the loading module. The row module is slightly larger than the loading module as a whole, effectively achieving the transition of the chicks from a disordered stacking state to a single row and orderly arrangement, facilitating subsequent individual sex detection.

[0033] In some embodiments, the fourth conveyor belt 17 has a higher conveying speed than the third conveyor belt 12. To achieve effective alignment, the conveyor belts in the alignment module run at a higher speed than the loading conveyor belts. This increases the distance between chicks after they enter the alignment module, ensuring that only one chick passes through and facilitating subsequent detection by the collection mechanism.

[0034] A V-shaped diverter plate combined with a differential conveyor belt structure is used to guide the disorderly arranged chicks into a single passing mode, and the speed difference between the conveyor belts is used to expand the distance between individual chicks, thereby providing stable individual identification conditions for subsequent sex detection.

[0035] In some embodiments, an infrared sensor is also included at the end of the conveyor belt to detect the passage of chicks. If no chicks are detected passing within a set time, the power supply of the motor corresponding to the conveyor belt is cut off.

[0036] For example, a third sensor 14 is provided at the end of the third conveyor belt 12 , and a fourth sensor 18 is provided at the end of the fourth conveyor belt 17 .

[0037] In some embodiments, an interactive module is further included, which includes a display screen; the interactive module is used to accept the number of images in the first sequence and the second sequence set by the user, as well as the proportion of detected gender images for determining the chick gender detection results; the display screen is used to display the gender detection results.

[0038] The system also includes an interactive module with a human-computer interface that monitors the equipment's operating status in real time and supports online adjustment of operating parameters and fault alarms, ensuring system stability, the continuity of the sorting process, and the accuracy of test results. These operating parameters include the number of first images, or the number of first and second images, and the ratio of sex detected in multiple first images, or the ratio of sex detected in multiple first and second images.

[0039] In combination with the above embodiments, the present invention uses four groups of comparative experiments to evaluate the effects of different stimulation methods and image acquisition strategies on the accuracy of sex judgment of one-day-old chicks. The four groups of experiments respectively use ramp stimulation, air blowing stimulation, simultaneous stimulation of ramp stimulation and air blowing, and a method of stimulating the ramp and air blowing successively but collecting image sequences separately, for comparison of sex judgment results. Among them, the first, second and third groups each collect an image for judgment, and the fourth group uses ramp and air blowing successively to stimulate and collect video streams separately. The two methods collect 5 frames of images for each chick, a total of 10 frames of images, and use a multi-frame voting mechanism to determine the sex: if the number of frames judged to be a certain sex is strictly greater than 5 frames, it is determined to be that sex, otherwise it is judged to be in doubt about the sex.

[0040] The image acquisition system used was the U3-3890CP-C-HQ industrial camera from IDS, Germany. Equipped with a CMOS area array image sensor and boasting a 12-megapixel (4096 × 3000) resolution, it can capture video at 34 frames per second at maximum resolution, meeting the requirements for high-quality image acquisition while also supporting multi-frame video capture scenarios. Compared to CCD cameras, CMOS cameras offer advantages such as fast response, low power consumption, and high sensitivity, making them suitable for accurately capturing the dynamic behavior of chicks in this experiment. The camera is equipped with a FOCViS UH0820 10MP C-mount lens with an 8 mm focal length, providing high-quality imaging at close range. The image acquisition system is operated using IDS peak Cockpit software, enabling flexible adjustment of parameters such as exposure time, frame rate, and white balance, ensuring stable and consistent image quality under varying lighting conditions.

[0041] For image processing and gender determination, a lightweight deep learning model based on SAG-YOLO is employed. This model replaces the original YOLO feature extraction module with the StarNet backbone network, significantly reducing the number of model parameters and computational complexity. The Additive CGLU module is introduced to optimize the original C2f module, combining an additive similarity function with a gating mechanism to effectively enhance multi-scale feature interaction and detail information capture. Furthermore, a detection head based on group normalization is constructed, and a shared convolutional structure is used to enhance the synergy between feature extraction and object detection.

[0042]

[0043] In summary, the system induces the chicks to instinctively spread their wings during a brief period of imbalance by adjusting the speed difference of the conveyor belt and the angle of the inclined conveyor device. Compared with relying on mechanical manual intervention or other compulsory methods to force the chicks to passively spread their wings, it can effectively reduce the physical damage caused by the equipment to individual chicks and improve the accuracy of detection and system stability.
