Today’s Patent – Wharf vehicle scheduling system, method, equipment and medium

The said invention (CN114023094B) was invented by Huang Xiusong, Yang Mei, Zhao Zhihong, He Tie, Li Shuzhi, Long Youtianjin patented by USPTO on 07-01-2022. Currently, it stands assigned to Shanghai International Port Group Co Ltd.

The present invention relates to the field of vehicle dispatching systems at docks, particularly addressing the challenges in coordinating unmanned and manned vehicles in mixed-operation scenarios. Existing solutions for port and pier storage yards rely on unmanned vehicles with limited operational capabilities, such as fixed routes, restricted areas, and inefficiencies in mixed-use environments with manually driven vehicles. These limitations lead to increased accident rates, low efficiency, and an inability to effectively plan tasks or handle emergencies. Furthermore, unmanned vehicles lack advanced scheduling mechanisms for tasks like charging or pre-dispatching, and the mixed-operation environment often results in operational delays and inefficiencies.

The invention introduces a comprehensive quay vehicle scheduling system that combines advanced modules for task distribution, single-vehicle dispatching, traffic control, and optimal path planning. Using algorithms such as the Hungarian algorithm and Floyd algorithm, it ensures efficient task allocation, minimal delays, and reduced accidents by considering factors like vehicle priority, task urgency, and optimal routes. The system also integrates pre-scheduling, real-time priority adjustments, and turn-optimization mechanisms for paths, enabling seamless coordination between unmanned and manned vehicles. This advancement improves loading/unloading efficiency, enhances safety, and enables emergency handling, offering a robust and adaptive solution for dock vehicle scheduling.
