摘　　要：针对目前煤闸门在遇到固体煤块大小不均匀的情况下容易造成闸板门卡住或开启、关断不到位的现象,提出了一种以智能识别技术和电磁接近开关技术为基础,以可编程控制器、电动机驱动、电机电流检测、闸门位置反馈和人机交互信号等组成的智能控制系统,实现煤闸门的控制,以实现煤闸门的精确定位,能避让大煤块等异物,实时监测驱动电机工作状况,保证煤闸门稳定运行。Regarding the situation that coal gate is difficult to open/close to the accurate position when uneven sizes of coal lump is put in,an intelligent control system has been put forward to realize the control for coal gates based on the technologies of smart identification and magnetic proximity switch.The intelligent control system consists of the programmable controller,motor driving device,motor current detector,gate position feedback unit and the human-machine interaction block,which can precisely position coal gate,effectively avoid foreign objects like big lump of coal,and real-timely monitor the working condition of drive motor,so as to ensure the stability of coal gate operation.
