Study On Path Planning Of Automatic Logistic System Based On Multiple AGV System

Since the first AGV is successfully excogitated by American Basrrett Electric Corp. in 1950s,AGVs are applied widely and a great deal AGV logistics systems are established in the domestic and oversea. JLUIV Research Group make great progress in the field of AGV navigation technology & control technology since the first AGV based on vision navigation is excogitated in 1999. At present JLUIV Research Group is studying the way to apply AGV based on vision navigation in enterprise production logistics, so it is very exigent to establish an integrated automatization logistics system. The paper makes some probe into monitor & control and traffic signal control for AGV logistics system. With the practical requirement of MAGVS, the research work of my paper, which obtains project finance, includes the following contents: 1. Research on path planning algorithm of a single AGV In the paper,I improve the path planning algorithm of single AGV on the base of electronic map of the netted road,applying connectivity-based path planning method.The algorithm raise the operation time of computer and decrease the time complication on the base of Dijkstra algorithm.We can obtain multiple path for a AGV at the same time. 2.An algorithm of path planning of MAGVS In virtue of planned path for AGV on the connectivity path planning method is theoretic.It can not meet the need of practicability.So I apply the dynamic shortest path algorithm.The time of waiting and changing path has taken account in the algorithm.It can meet the demand of automation logistics system in a certain degree.The algorithm is effective through experiement for multi-AGV.
