Docking method for container terminal management system and automatic driving container truck

Abstract

The invention relates to a docking method for a container terminal management system and an automatic driving container truck, which is characterized in that the automatic driving container truck is guided to an operation bay according to a dispatching command of the container terminal management system after a network system is established so as to realize a first stage of dispatching performed by the container terminal management system on the automatic driving container truck; and then a container gantry crane provides centimeter-level precise guidance to guide the automatic driving container truck to accurately stop in an operational area of container loading / unloading so as to realize a second stage of docking, so that the accurate docking of the container terminal management system and the automatic driving container truck is completed. The beneficial effects are that a double guidance docking method is adopted, the method is divided into a stage in which the container terminal management system dispatches the automatic driving container truck and a stage in which the container gantry crane guides the automatic driving container truck, and the two stages cooperate and coordinates together to effectively guide the automatic driving truck to accurately stop at the operation bay.

Description

technical field [0001] The invention belongs to the field of automatic driving, and in particular relates to a docking method between a container terminal management system and an automatic driving container truck. Background technique [0002] Self-driving vehicles are a comprehensive system that integrates environmental perception, planning and decision-making, and multi-level assisted driving. It uses computer, modern sensing, information fusion, communication, artificial intelligence, and automatic control technologies. It is a typical High-tech complex. [0003] The operation specification for vehicle loading and unloading operations at the wharf is: the vehicle must stop within the operating area of ​​the container gantry crane. Therefore, the positioning accuracy requirements for self-driving container trucks are relatively high, generally less than 20 cm. In the prior art, errors in the control algorithm and sensor transmission will affect the location accuracy of ...

AI Technical Summary

Problems solved by technology

In the existing technology, the error of the control algorithm and sensor transmission will affect the position accuracy of the self-driving vehicle.

At present, it is difficult to accurately control within the range of 20 cm. Therefore, in the actual loading and unloading process at the terminal, manual driving or manual assistance is required to complete the operation. This kind of work is extremely dangerous and requires a lot of manpower support.
