Vehicle Dispatching And Control Method For Automatic Vehicle Logistics Park And Simulation

In 2020,China's logistics industry has experienced unprecedented severe challenges and achieved hard-won achievements.The indexes of highway logistics,warehousing,express logistics and e-commerce logistics are all in the expansion range.The strength and resilience of the logistics industry has made an important contribution to the transformation of China's economic operation from negative to positive.The logistics park is an important infrastructure and the main carrier in the process of logistics operations.It is the concentrated area of logistics operations.At the junction of several modes of transportation,it also undertakes important logistics functions such as storage,processing and transportation.The level of informatization and automation of logistics park is constantly improving,and the pure automated logistics environment is also developing rapidly.In the logistics park,not only the management of vehicles needs to be more standardized,but also the real-time monitoring requirements of people,vehicles and goods are getting higher and higher.Vehicle automation in the logistics park automation process as an important link,the way of its automation is the focus of research.As an important link in the operation of logistics park,most of the vehicle transportation is still controlled by manual,with low transportation efficiency and high transportation cost.Therefore,the establishment of a fully automatic driving logistics park is the development direction of improving transportation efficiency and reducing transportation costs.In the fully automatic driving environment,in order to optimize the overall traffic system,the first need is the strong driving behavior execution ability based on the automatic driving technology;Secondly,the automatic vehicle dispatching method is the key to automatic logistics park.In the process of realizing the automatic environment of transportation vehicles in logistics park,it is the combination and innovation of the theory and method of automatic vehicle transportation trajectory calculation under the new background.It is also to realize the conflict coordination of the automatic vehicle transport track,and improve the efficiency of logistics transport under the automatic vehicle environment.In this paper,A~* algorithm is selected to carry out path planning and conflict analysis on the track running of the automatic car.A~* algorithm is efficient and convenient in dealing with intelligent path finding under the premise of obstacles,and corresponding heuristic functions can be specified to search the path when searching the path.This algorithm can reduce the number of nodes to search,so as to improve the efficiency of path search.While ensuring the optimal path,the search quantity is greatly reduced and the efficiency is improved.In path planning problem based on A * algorithm on the basis of introduction of collision heuristic algorithm,when more than one auto transportation at the same time,in the node to the next node are occupied by the other vehicle information collection,so as to realize path planning under the shortest path,and also prevents the automotive collision problem in the process of driving.In this paper,Any Logic software is used to simulate the model and verify its feasibility.In this paper,some results on automotive vehicle path planning problem,the shortest path planning is not only a single car,at the same time also in a number of automotive drive on the question of how to avoid a collision was studied,which is beneficial to optimization of path problem,and also on the path planning problem for automotive improve the efficiency of the transportation.
