摘　　要：针对铸造车间铸件转运自动化程度低、人工劳动强度大、车间环境差、安全性低的现状,采用轨道导引车(RGV)输送方式,设计了一种基于RGV的柔性动态调度系统,满足铸件在各工位间自动化输送。硬件系统由RGV、电动转盘、轨道搭建,通过钢轨和电动转盘将各加工工位串联,形成“田”字型输送轨网,RGV采用编码器完成行驶路径的记录,采用载码体标签RFID完成停靠位置记录和位置矫正,设计调度任务优先级,建立邻接矩阵算法模型,通过RGV的节点扫描和路径计算,编译了RGV柔性动态调度系统。该系统解决了RGV输送系统在直线、环形输送轨网下易堵塞、柔性差等问题,实现了在“田”字型轨网下,多台RGV在多工位间的路径规划、柔性调度,通过该系统的应用,极大地提高了铸件在车间转运的效率。In view of the low degree of automation,high labor intensity,poor workshop environment and low safety of casting transfer in caption foundry,a rail guided vehicle(RGV)flexible dynamic scheduling system is designed to automatically transfer casting.The hardware system is built with RGV,electric turntable and track.The processing stations are connected through the steel rail and electric turntable.RGV records the driving path with an encoder,records the parking position and corrects the position with RFID,designs the scheduling task priority,establishes the adjacency matrix algorithm model,and compiles the RGV flexible dynamic scheduling system through RGV node scanning and path calculation.The system solves the problems of RGV conveying system that is easy to be blocked and has poor flexibility under the rail network,and realizes the path planning and flexible scheduling of multiple RGVs between multiple stations under the combination rail network.Through the application of the system,the efficiency of casting transfer in the workshop of caption foundry is greatly improved.
