针对煤矿现在使用的监控系统因为电磁干扰的影响出现假数、大数现象,提出通过改进通信方式解决电磁干扰问题。分站与传感器选用串行码传输,以RS-485通讯方式为例作为介绍;分站与地面主机选用光纤+FSK方式,即满足监控系统的速度要求,又保障了传输的准确性。
For the coal mine monitoring system now used because of the impact of electromagnetic interference appear false, the number of phenomena, proposed by improving the communication to solve the problem of electromagnetic interference. Substation and sensor selection serial code transmission, RS-485 communication as an example as an introduction; sub-station and the host using fiber optic + FSK mode, that is, to meet the monitoring system speed requirements, but also to ensure the accuracy of the transmission.
