Description

Technical Field

[0001] The utility model relates to the technical field of container truck ingress and egress management control, in particular to an integrated door control system for container truck ingress and egress management in a freight yard. Background Art

[0002] In traditional railway freight yards, container trucks entering and leaving the freight yard gates are generally controlled by on-site manual copying, which is time-consuming and labor-intensive, and has low efficiency. With the continuous growth of railway container shipments, there is a great pressure on the import and export operations of railway freight yards. Under this situation, intelligent and smart management of railway freight yards has become the current development trend. More and more freight yards collect data on the container box number and license plate number of container trucks based on image acquisition and processing, character recognition and other technologies, and based on this, realize the automated control and management of the entry and exit gates of container trucks.

[0003] However, the existing automatic management and control systems for cargo yard gates often have problems such as complicated and inflexible hardware installation structures. When installing and setting up the equipment, the installation position and pitch angle of the camera or other image acquisition components are generally designed based on the types of containers of general specifications that account for a large proportion of the image acquisition objects. However, when encountering containers of certain special specifications, or when the container truck is located in a relatively biased position in the channel, due to the poor shooting angle, the collected images will have poor clarity or distortion of the identified elements, resulting in errors in the recognition algorithm or even failure to recognize. Once such problems occur, manual intervention can only be used to proofread and re-record information such as the container number. The above problems will affect the efficiency of container trucks passing through, causing queues and congestion when trucks enter and exit the cargo yard gates. Summary of the invention

In this embodiment of the utility model, a third distance sensor can be set on the main body. When the distance between the tail of the container and the main body obtained by the third distance sensor exceeds the preferred preset shooting distance, the third adjustment mechanism is triggered, and the third driving unit drives the second slider to drive the main body to move in the direction of the truck, thereby shortening the distance between the second camera and the tail of the container, so that the distance is kept within the preferred preset shooting distance range, and the time window in which the second camera can capture the optimal frame is extended. In this way, even if the container truck does not stop in the channel and passes the gate at a low speed, it can ensure that the tail box number obtains a higher recognition accuracy, thereby improving the passing efficiency of the container truck at the cargo yard gate.

[0072] In a more preferred embodiment of the present invention, a fourth ranging sensor is further provided on the main body. When the distance between the container head and the main body obtained by the fourth ranging sensor is less than the optimal preset shooting distance, the third adjustment mechanism is triggered, and the third driving unit drives the second slider to drive the main body to move in the driving direction of the truck, thereby extending the distance between the first camera and the container head, so that the distance is maintained within the optimal preset shooting distance range, and extending the time window in which the first camera can capture the optimal frame.

[0073] By adopting the integrated gate control system for container truck entry and exit management in the cargo yard of the utility model, the accuracy of container number recognition can be increased to more than 99% for both general-specification containers and special-specification containers, thereby improving the passing efficiency of container trucks at the cargo yard gate.
