摘要
为实现矿井提升机的全自动控制和保护,提升其安全性和可靠性,为矿山生产的安全和效率提供保障,提出基于冗余PLC控制的矿井提升机的全自动交流调速系统。该系统通过变频调速实现矿井提升机的全自动无极调速。实践证明,采用冗余PLC控制的矿井提升机调速系统完全可以实现自动化控制与保护,同时还可以有效节能。随着其在工矿中的实际应用,矿井提升机的安全性和使用效率将大幅度提高。
In order to realize the automatic control and protection of mine hoist,enhance its safety and reliability,and guarantee the safety and efficiency of mine production,a fully automatic AC speed regulation system of mine hoist based on redundant PLC control was proposed.The system achieves full automatic speed regulation of mine hoist by frequency conversion speed regulation.Practice has proved that the mine hoist speed control system controlled by redundant PLC can fully realize automatic control and protection,and also can effectively save energy.With its practical application in industry and mining,the safety and efficiency of mine hoist will be greatly improved.
