介绍了煤矿井下违章爬乘带式输送机的人员检测、报警方法。并利用89C52单片机控制步进电机,设计了一款旋转门阻式输送带防爬人系统。可以在输送机不停车的情况下,有效地预防违章爬乘人员掉入煤仓或转载仓等事故的发生。
This paper introduces the personnel detection and alarm method of unmanaged climbing belt conveyor in coal mine. And using 89C52 single-chip stepper motor control, design a revolving door resistance conveyor belt anti-climb system. In the case of conveyor does not stop, it can effectively prevent accidental climb crew fall into coal bunker or transfer bin and other accidents.
