摘要
继电控制利用布线逻辑来实现各种控制,需要使用大量的机械触点,由于电器不断老化,使得控制系统运行的可靠性很差,维修任务量大,亟需改造更新。
The black-white control realizes each kind of control using the wiring logic,needs to use the massive mechanical electronic contacts. The reliability of the control system deteriorate due to aging of electric appliance,resulting to much maintenance work. Transform and renewal of the control system is urgent.
