摘　　要：为解决堆场单机自动化改造实施过程中行走位置获取不精确和实时性差的问题,设计了一种高性能的单机行走控制系统,系统将PLC、编码器、变频器、RFID模块以及HMI人机界面连接成一个整体,HMI发出动作指令后,变频器控制电机转动,通过绝对值编码器实时地上传编码数据,然后利用校正后的位置和速度数据来实现单机的各种行走及保护功能,并对重要数据提供冗余。有效提升堆场单机自动化整体的安全性能和生产效率。To solve the problems of inaccurate travelling position and poor real-time performance in the process of automatic transformation of a single machine in the yard,a high-performance travelling control system is designed,which integrates PLC,encoder,frequency converter,RFID module and HMI man-machine interface.After the HMI sends out the action command,the frequency converter controls the motor to rotate,uploads the coded data in real time through the absolute value encoder,and then realizes various travelling and protect the single machine according to the corrected position and speed data,and redundancy is provided for important data,which can effectively improve the safety and production efficiency of automatic operation of a single machine in the yard.
