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 the extensive use of a large number of frequency conversion equipment in coal mines and other high-power electrical equipment, the generated high harmonics and electromagnetic pulses will interfere with the transmission of gas signals detected by the monitoring system, so that the monitoring system can not provide accurate and reliable Monitoring data. This paper discusses a design based on DSP filter, which can effectively reduce the influence of high harmonics and electromagnetic interference on gas signal transmission, and avoids the mine safety production due to high value power interruption, communication interruption and other failures caused by interference .
