Research On The Path Planning Of Multiple AGVs In The Automatic Auxiliary Material Warehouse Of The Tobacco Factory

In this paper,with the automatic conveying system of the accessory nozzle of an enterprise Automatic Guided Vehicle(AGV)as the background,from the point of view of solving the traffic jam in the multiple AGV moving process of the accessory nozzle bar,it will affect the normal operation of other AGV vehicles and even the paralysis of the transport system,the path planning algorithm of the AGV is studied to meet the requirements of the multiple AGV transportation task.And to take effective measures to the busy road,so as to avoid multiple AGV workshop conflict problems,to ensure that the shortest path to complete the transport task,to improve the production efficiency of enterprises has a strong practical significance.In this paper,the problem of multiple AGV path planning in the accessory Nozzle bar processing area is studied,and the main contents are as follows:(1)In this paper,the algorithm and effect of multiple AGV driving path at home and abroad are analyzed.(2)This paper studies the structure,workflow and operation process of the automated warehouse in this enterprise.In addition,the overall scheme design of AGV,including system composition,car body composition,AGV guidance method,control system and dispatching system are also analyzed in detail.(3)The algorithm of single AGV and multiple AGV Trolley's driving path is studied.The topological modeling method of electronic map modeling using accuracy and high efficiency.In this paper,according to the path busyness in a period of time,the busy factor is added to improve the Dijkstra algorithm,the Dijkstra algorithm and the improved Dijkstra algorithm are combined to make path planning for single AGV,the improved Dijkstra algorithm is simulated and analyzed,and a good effect is obtained,the path planning method based on time window and the priority traffic law method are used to route the multiple AGV,and the various conflicts in the process of multiple AGV are solved.(4)The simulation and experimental analysis of single AGV,multiple AGV path planning and multiple AGV conflict were carried out according to the actual operation electronic diagram of AGV in the enterprise accessory nozzle bar processing area.The experimental results show that the single AGV and multiple AGV path planning algorithm used in this paper can better guarantee the normal running of AGV,and solve all kinds of conflicts in the driving well,and meet the demand of AGV optimal dispatching in the processing area of accessory nozzle bar.
