我国铁路道砟的清筛主要依靠小型清筛机来完成,但是作业效率低、清筛质量差、故障率高,目前正在研发大型边坡清筛机来改善这些问题.本文主要研究和设计边坡清筛机控制系统.通过分析清筛机的基本结构和工作原理,提出控制要求,在硬件方面实现了PLC的选型、电气系统设计和搭建,软件方面完成了PLC控制程序和HMI控制界面.本系统是技改项目且已经验收,达到各项指标要求.
The cleaning of the railway tracks in our country depends mainly on the small size cleaning machine, but the operation efficiency is low, the cleaning quality is poor and the failure rate is high, and large scale slope cleaning machines are being developed to improve these problems.This paper mainly researches and designs Slope cleaning machine control system.By analyzing the basic structure and working principle of the cleaning machine, put forward the control requirements, in the aspect of hardware, the selection of PLC, the design and construction of electrical system are completed, and the software of PLC control program and HMI control interface The system is a technical transformation project and has been acceptance, to meet the requirements of the indicators.
