旧的直流矿井提升机控制系统采用大量的继电器和接触器,噪声和维修工作量大,对旧的电控系统进行改造势在必行。利用PLC、DCR600M+DCR600S等全数字设备,采用一种新的控制模式,即:上位机监控(工控机)+PLC冗余控制+智能变流装置,在提升机井筒和导向轮上配置轴编码器。对提升机电控系统的调节系统、操作保护系统、行程监控系统等进行改造,实现了全数字式闭环控制。
The old DC mine hoist control system uses a large number of relays and contactors, noise and maintenance workload, the transformation of the old electronic control system is imperative. The use of PLC, DCR600M + DCR600S and other digital devices, the use of a new control mode, namely: PC monitoring (IPC) + PLC redundancy control + smart converter device, the hoist shaft and guide wheel configuration axis coding Device. The hoist electromechanical control system of the adjustment system, operation protection system, travel monitoring system, and other transformation, to achieve a fully digital closed-loop control.
