The medium in this embodiment is gas.

The working principle of this embodiment is:

① Under normal conditions, the main slider 41 will move leftward under the elasticity of the main spring 42 and extend out of the horizontal inner hole 40 until the first guide block 51 contacts the side filler block 44 and encounters resistance and stops moving rightward. At this time, the push-down block 61 will move downward under the elastic force of the two auxiliary springs 62 and extend out of the inner cavity 60 until the lower guide block 72 contacts the square stopper 75 and encounters resistance and stops moving downward.

② During installation, insert the air nozzle of the mobile small air pump into the external fixed interface 56, and then start the small air pump. The small air pump can generate gas and introduce it into the main guide cavity 54 through the main guide hole 55. The gas is then introduced into the auxiliary guide cavity 76 through the inner opening 81 and the connecting hole 82. The auxiliary guide cavity 76 receives the gas. After the auxiliary guide cavity 76 is filled with gas, it will expand, the upper guide block 71 moves upward, and the lower push block 61 is driven to move upward and hidden in the inner opening cavity 60 to avoid hindering the right movement of the main slider 41.

③ Then, the main guide cavity 54 expands after being filled with the medium, the second guide block 52 moves rightward, and the main slider 41 is driven to move rightward and hide in the horizontal inner hole 40 to avoid hindering the insertion of the removable circuit board 32.

④ After the removable circuit board 32 is inserted into the installation cavity 30, the main slider 41 will move to the left under the elasticity of the main spring 42 and extend out of the horizontal inner hole 40 until the first guide block 51 contacts the side filler block 44 and stops moving to the right due to resistance. At this time, the main slider 41 is located above the removable circuit board 32; then, the push-down block 61 will move down under the elastic force of the two auxiliary springs 62 and extend out of the inner cavity 60, and the push-down block 61 will push the removable circuit board 32 downward, so that the multiple electrical pins 35 can be respectively inserted into the corresponding electrical sockets 34, thereby realizing the electrical connection between the main circuit board 31 and the removable circuit board 32 after mating.

⑤ Insert the heat dissipation fan 33 into the installation cavity 30 until the heat dissipation fan 33 abuts against the two second support pillars 321 .

⑥ The steps for disassembly are the same as steps ② and ③. When the main slider 41 is driven to move right and hidden in the horizontal inner hole 40, apply force upward to take out the cooling fan 33, and then apply force upward to take out the detachable circuit board 32.

It needs further explanation:

The main control circuit in this embodiment includes a communication circuit, an auxiliary power supply circuit, a 3.3V power supply circuit, a drive circuit, a single-chip microcomputer, a 3.6V power supply circuit, a fill light circuit, and a camera module 27 connection circuit, as shown in Figures 8-15. This embodiment discloses a detailed circuit diagram, and those working in the electronics field should and should know that the disclosed circuit diagram is feasible.

This embodiment also designs an adapted operating software that can be run on the terminal, and the flowchart of the operating software is shown in Figure 16.

This embodiment also designs an artificial intelligence algorithm for controlling the automatic movement of the camera module 27, as shown in Figure 17, which discloses a deployment diagram of the yolov5 algorithm.

The Yolov5 algorithm is used, and Yolov5 uses TensorRT for c++ deployment.

1. Algorithm principle;

YOLOv5 is an object detection algorithm known for its speed and accuracy. It uses a single-step process, using a neural network to directly predict the location and type of objects in an image. This algorithm learns the characteristics of the image and combines it with a predefined framework to determine the exact location of the object. During training, it adjusts itself to more accurately identify and locate objects, while using data enhancement techniques to improve its adaptability to different environments and changes. YOLOv5 is able to simultaneously identify multiple objects in an image, regardless of their size, which makes it very suitable for application scenarios that require fast and accurate object detection. 2. Network structure;

The algorithm architecture mainly consists of four parts: input, Backone, Neck and Prediction.

2.1. Input terminal;

YOLO v5 improves training efficiency and model accuracy through several key technologies: Mosaic data enhancement, adaptive anchor box calculation, and adaptive image scaling.

Mosaic data augmentation: The model is trained by randomly scaling, cropping, and combining four images into a new image. This not only increases the background complexity of object detection, but also improves the model's ability to handle diverse data, allowing the model to learn effectively when receiving more diverse inputs.

Adaptive anchor box calculation: It is a unique feature of YOLO v5. It can automatically calculate the most suitable anchor box size based on the training data, so that it can better match the target objects in the data set, thereby improving the accuracy of detection. The introduction of this technology eliminates the need for manual preset anchor boxes for model training, greatly simplifying the preparation work for model training.

Adaptive image scaling: This solves the scaling problem caused by inconsistent image aspect ratios. By minimizing the black edges of the images, it ensures that the images can be input into the model for training in the optimal form while maintaining their original proportions. This not only retains more image information, but also avoids information redundancy caused by too many black edges, further improving the model's inference speed.

2.2.Backone Network;

The Focus structure increases information channels through special slicing and extracts features without information loss; the CSP structure divides the feature map and performs partial convolution and then merges it to reduce the amount of calculation and improve efficiency.

2.3.Neck network;

The Neck of yoloV5 still uses the FPN+PAN structure, but some improvements are made on its basis. In the Neck structure of yoloV4, ordinary convolution operations are used, while in the Neck of yoloV5, the CSP2 structure designed by CSPNet is used, thereby enhancing the network feature fusion capability.

2.4. Loss function;

CIOU_Loss: adds an influencing factor based on DIOU_Loss, taking the aspect ratio of the prediction box and the GT box into consideration;

CIOU Loss (Complete IoU Loss) adds two additional influencing factors based on DIOU Loss (Distance-IoU Loss) to more comprehensively consider the difference between the predicted box and the true box:

2.4.1 Aspect Ratio Term: Usually the aspect ratio of the predicted box and the real box is different, which will lead to inaccurate IoU calculation. To solve this problem, CIOU loss introduces an aspect ratio factor to measure the difference between the aspect ratios of the predicted box and the real box.

2.4.2 Center Point Distance Term: The traditional IoU loss only focuses on the intersection and union of two boxes, but does not consider the distance between their center points. CIOU loss takes this into account by introducing a center point distance factor to better measure the relative positions of the two boxes.

The formula for CIOU loss is as follows:

CIoU = 1 - IoU + c^2 * p^2 / diag^2(b, b_gt) + a * v

in:

IoU is the intersection over union of the predicted box and the true box.

c^2 * p^2 / diag^2(b, b_gt) is the aspect ratio factor, where c is a constant, p is the distance between the diagonals of the predicted and true boxes, and diag(b, b_gt) is the square of the length of the diagonals of the predicted and true boxes.

a * v is the center point distance factor, where a is a constant and v is the distance between the center points of the predicted box and the true box.

The CIOU loss designed in this way can more comprehensively consider the difference between the predicted box and the true box, thereby improving the performance of the object detection task.
