Research On System Design And Scheduling Control Of Mesh Drive Type Handling AGV

Today’s warehousing and logistics industry is developing rapidly.As an intelligent equipment,AGV is gradually used in warehouse handling operations.Compared with manual handling,the use of AGV can improve handling efficiency,but with the rapid growth of handling tasks.The traditional use of batteries as the power supply the shortcomings of AGV operation time and high maintenance cost are exposed,and it is difficult to meet the needs of modern warehousing.In order to overcome the shortcomings of the AGV’s battery life caused by the inherent defects of the battery.On the basis of reading literature and entering AGV design and manufacturing enterprise internship,the current application status of AGV is summarized,and an mesh-driven AGV is designed.This subject is based on the working methods of a distribution warehouse and the requirements for commodity handling.Firstly,Completed the overall scheme design of mesh-driven AGV.Drawing on the split design concept,the walking drive module and the omnidirectional transfer module were separated and adopted Engagement drive mode;Followed by detailed structural design of walking drive module and omnidirectional transfer module,design calculation and selection calculation of key components,determination of the model of each drive motor and reducer,and verification of key parts using simulation software reliability;Once again,the hardware of the mesh-driven AGV is designed,the selection of the main controllers,electrical devices,and communication methods of each module is completed.Then the servo control scheme of the mesh-driven AGV is presented,and the PID speed control scheme of the walking gear is introduced;Complete the construction of the global map of the AGV storage system for mesh-driven transportation.Through analysis of the more commonly used path planning algorithms.The A*algorithm is used to plan the AGV’s driving path,and the selected A*algorithm is optimized;Finally,the scheduling strategy of mesh-driven AGV is researched,and the definition and priority of task assignment are clarified,and the conflict prediction and solution based on time window are proposed for the conflicts during multi-AGV driving.Window multi-AGV conflict resolution,confirmed the feasibility of the program.The mesh-driven AGV can effectively overcome the traditional AGV’s influence from the inherent defects of the battery,increase the battery life,improve the handling efficiency,and have a broad application market.
