[0031] The present application will be further described below in combination with the drawings and embodiments.

[0032] Embodiment 1:

[0033] The specific composition and working principle of the loading heavy cargo safety monitoring device are as follows:

[0034] The sandwich box 1 is made of high-strength aluminum alloy material, with the characteristics of light weight, high strength and corrosion resistance. The size of the box is 1200mm×800mm×600mm, and the inside is divided into two main parts: the equipment cabin and the battery cabin. The equipment cabin is used to install electronic devices such as edge calculator, wireless transmission and alarm module, power supply 6; the battery cabin is used to place backup batteries to ensure that the device can still work normally without external power supply.

[0035] The camera 2 adopts a 360-degree rotating high-definition camera with 30 times optical zoom and 120-degree wide-angle view. The camera 2 is connected to the top of the sandwich box 1 through an electronic hydraulic machine 5, which can realize a vertical telescopic range of 0-2 meters to adapt to the monitoring of goods of different heights.

[0036] Each telescopic support arm 3 is made of stainless steel and has a built-in hydraulic cylinder controlled by the electronic hydraulic machine 5. After the telescopic support arm 3 is extended, its end has an adjustable clamp that can be firmly fixed to the side wall of the container.

[0037] The support leg 4 adopts a foldable telescopic design for easy storage, is made of high-strength alloy steel, and has a locking mechanism to ensure stable support of the sandwich box 1 after unfolding.

[0042] The sensor in this embodiment is a wireless ultrasonic sensor, which uses high-precision ultrasonic measurement method, with a range of 0.05-4.5 meters and an accuracy of ±1mm, and is fixed on both sides of the container by magnetic attraction.

[0043] The mobile terminal equipment can be a smartphone or tablet computer equipped with a special application program for receiving real-time monitoring data and alarm information.

[0044] According to the above principles and specific structures, the operation steps during use are as follows:

[0045] Place the sandwich box 1 in the central position inside the container, unfold the support legs 4 and lock them to ensure the stability of the device. Control the extension of the telescopic support arm 3 through the electronic hydraulic machine 5, and fix the clamp on the side wall of the container. Start the camera 2, adjust the height and angle of the camera 2 through the control of the electronic hydraulic machine, and ensure that the overall appearance of the goods can be clearly captured. The edge calculator performs self-checking, initializes the deep learning model YOLOv8, and establishes a connection with the camera 2 and the ultrasonic sensor. The edge calculator starts to receive image data collected by the camera 2 and distance data collected by the ultrasonic sensor. The edge calculator pre-processes the image data, including denoising, contrast enhancement and image flipping, etc., and then uses the YOLOv8 model for feature extraction and analysis, combined with ultrasonic data, to identify the position of the goods and calculate the offset. The program of the edge calculator for image data processing belongs to the prior art, and will not be specifically explained in this embodiment.

[0046] When the offset of the detected object exceeds the preset threshold, for example, exceeds 10 cm, the wireless transmission and alarm module is activated, sends alarm information to the mobile terminal device through the 4G / 5G network, and starts the on-site LED indicator light and buzzer alarm.
