In recent years, with the continuous development of my country’s economy, the port container business has grown rapidly, and the demand for increasing throughput has become stronger and stronger. At present, the technical methods of domestic terminals are generally backward. Due to manual intervention, many gates have caused long queues of vehicles in front of the gates, and errors caused by manual recording have increased the burden of repeated processing by the system. Many of the above problems have led to a decline in the service level of the terminal, which not only affects the living environment of the terminal itself, but also causes the import and export enterprises in the area covered by the terminal to suffer greater economic losses.
Container damage inspection is an unavoidable inspection work for containers entering the port terminal, mainly to prevent disputes caused by the damage of the container between the transportation enterprise and the terminal. In the past, this work was manually recorded by the entry gate staff entering the crossing, and it was necessary to climb a higher gallery bridge to check the top surface of the box, which was dangerous and inaccurate in handling. This system presents the box surface image on the computer screen through the advanced logic control system and the picture acquisition system, so that the disability inspector can complete the damage detection as long as it is in front of the computer.
【System Principle】
When a container truck enters the aisle, the photoelectric sensors fixed on both sides of the aisle detect the position of the container. The control system controls the cameras corresponding to each side to take pictures according to the conduction and interruption status and timing of the sensors. The image data is collected in real time and processed by the computer, optimized and processed by a special algorithm, for background use.
The system consists of the following parts:
1. Front-end photoelectric trigger device;
2. Front-end image acquisition equipment (including light source assistance);
3. Back-end logic control equipment;
4. Back-end detection algorithm software;
5. Back-end query and communication software;
【Overall structure of the system】
BS structure can connect multiple lanes at the gate of the terminal at the same time. The 4 cameras installed in each lane are connected to the video capture card through the national standard video cable, and the optoelectronic equipment is statistically managed by the logic control device to ensure the correct image capture logic and prevent the interference of the spoiler or other objects in the front of the car. Unified management through the computer room. The overall structure of the system is shown in Figure 1.

By connecting the detection system with the on-site computer, it can provide the back-end system with a real-time picture of the vehicle-mounted container, and can zoom in on each side for more careful inspection by the disabled inspection personnel, and generate relevant reports.
This system has the following technical advantages:
1. Under various terminal weather conditions, it can handle three situations: one small box, two small boxes, and one long box;
2. The gantry bracket is adopted, which occupies a small space and is more suitable for the transformation of the old gate; it can be reused with the box number identification system to reduce the system cost;
3. The processing time varies according to the length of the box, generally it can be completed quickly after the truck is loaded with the weighbridge;
4. The detection system is reliable and can work effectively without being affected by the truck loading container type, double-box gap, and container placement position.
5. Through the training auxiliary algorithm, the suspicious area of damage is automatically delineated, and the inspector is prompted to zoom in on the image and inspect it carefully or on-site.
6. Data query function, data and images can be stored for a long time, and support a variety of data communication functions to facilitate third-party integration;
【Application Effect】
Through the container container damage detection system implemented at several terminal gates, the containers entering and leaving the terminal are effectively managed, and the speed of vehicles entering and leaving the port has increased significantly. Each container entering the port has an image record to help the terminal to determine the responsibility in the event of a dispute. , Get praise from customers.
