[0031] like Figures 1-3 As shown, in this invention, a camera 15 is mounted on a camera bracket 14 within the sliding body. This camera is used to capture high-definition images of the cattle farm in real time and transmit them to the HZ-EVM-RK3576 development board. The camera bracket 14 is fixed to the output shaft of servo motor 13, and the servo motor bracket 12 is fixed to the output shaft of servo motor 11. Servo motor 11 is used to achieve left and right rotation of the camera, and servo motor 13 is mounted on the servo motor bracket 12 to achieve up and down rotation of the camera. The drive motor 4 is connected to the drive wheel 3 via a horizontal wheel axle 30, enabling the sliding body 1 to move left and right. The HZ-EVM-RK3576 development board 6 is installed inside the sliding body 1 to receive image data from the camera 15, process the image data, and send the image data to the cloud. The HZ-EVM-RK3576 development board 6 is equipped with a YOLO 11 module. The system employs a model and tracking algorithm to output the target center coordinates, which are then sent to the STM32 system board. The STM32 system board 5 is installed inside the slider 1 and is used to receive the coordinates output by the HZ-EVM-RK3576 development board 6. Based on the coordinate positions, it controls the servo motor 11, servo motor 2 13, and drive motor 4. The WiFi module 7 is used to send and receive data to and from the cloud.

A pulley 16 is provided on the outer side of the middle part of the device to reduce friction with the slide rail 2 while stabilizing the movement trajectory of the main body. A metal charging head 17 is located on the outer side of the rectangular frame 21 in the middle of the slider 1, which is used to contact the charging groove 19 on the slide rail 2 to realize the charging function.

[0032] like Figure 4 As shown, the slide rail 2 consists of an upper rectangular frame 25, a middle rectangular frame 26, a lower rectangular frame 27, and four support pillars 28, forming the main frame of the slide rail.

The STM32 system board 5 uses a high-performance processor and, based on the center coordinates of the target cattle, precisely controls servo motors 11 and 13, as well as the drive motor 4, using a PID algorithm and the FreeRTOS real-time operating system. Servo motor 11 enables the camera 15 to rotate left and right, servo motor 13 enables the camera to rotate up and down, and the drive motor 4 drives the drive wheel 3 via the horizontal axle 30, enabling the main body to move left and right within the slide rail 2, thus achieving the left and right movement of the night vision camera 15 and enabling accurate identification and tracking of the target animal.
