摘要
通过对TKD-A系列矿井提升机电控系统的分析,用PLC技术对老式矿井提升机的控制方式进行改造,主要是运用PLC内部的软件去实现原有系统的继电器、接触器控制逻辑,这样在不改变矿井提升机功能、安全保障的情况下,可以大大提高系统的安全性,可靠性和生产效率。
Based on the learning of the TKD-A series mine hoister electric control system,renovated this old system with the PLC technology. So the soft element in PLC will take the place of electric relay and contact control logic which will greatly advanee the security, reliability and efficiency of the system.
