摘　　要：针对煤矿采掘机械监控系统井下工作环境恶劣,引起干扰的情况复杂等特点,分析了煤矿井下引起干扰的主要干扰源,并且从供电电源、信号传输通道和提高监控系统敏感元件的抗干扰措施三个方面进行了硬件抗干扰设计,并结合数字滤波器、软件冗余等软件抗干扰措施,实现了监控系统的抗干扰设计,并对其它严酷环境下系统的抗干扰研究具有参考作用。The working environment is bad for the monitoring and control system of mining and drivage equipment in coal mine and the interference cause is complex in the situation. The main source of interference is analyzed in the underground of coal mine, and three aspects of the hardware anti- interference measures are put forward including the power supply, signal transmission channel and improve the monitoring system of the sensing elements. At the same time the software anti interference measures are put forward incluing digital filter, software redundancy. The anti-interference design of monitoring and control system is completed and has the reference function for other study of anti interference system in the harsh environment.
