摘　　要：随着煤矿井下大量的变频设备以及其他大功率电气设备的广泛使用,所产生的高次谐波和电磁脉冲都会对监控系统所检测的瓦斯信号的传输产生干扰,使监控系统无法提供准确可靠的监测数据。论述了一种基于DSP滤波器的设计,它可以有效地减少高次谐波和电磁干扰对瓦斯信号传输的影响,避免了因干扰产生的高值断电、通讯中断等故障而影响矿井安全生产。With a lot of coal mine underground frequency equipment and other high-power electrical equipment widely used ,meanwhile they are having generated higher harmonic and electromagnetic pulse ,and the monitoring system of the signal detection gas transmission would cause trouble, thus, it make the monitoring system can＇t provide accurate and reliable monitoring data. This paper discusses one of the design of a filter base on DSP, it can effectively reduce the high frequency harmonic and electromagnetic interference signals to influence the gas, and it can avoid the interference to high value for the power, communication interrupts and others faults which will affect the safety production.
