摘要
针对矿区现有提升机的运行缺陷,提出一种通过变频器和S7-200PLC控制提升机的方案。该方案采用上位机实时监控工作状态,并设置了安全保护措施和故障处理功能,提升机的速度给定采用PLC控制软件生成S形速度曲线实现。系统具有可靠性高,灵活性强,故障率低等优点。
For the mine existing hoist operation defect,the article puts forward an through converter and S7-200 PLC to control the elevator scheme.The scheme adopts the upper machine working state real time monitoring,and set the safety protection measures and fault processing functions,hoist speed given PLC control software generating S speed curve to realize.This system has high reliability,flexibility,low failure rate advantages.
