Research of frequency signal transmission of mine-used sensor

摘要: 针对矿用模拟量传感器采用的频率信号传输制式受外界干扰大而容易造成安全监控系统误报警、误断电的问题，分析了频率信号的传输特性和干扰特性，提出了采用差分传输、正弦波传输、电流传输、总线传输、降低传输频率等抗干扰措施，并指出多主方式的CAN总线是矿用传感器信号传输制式的发展趋势。

Abstract: In view of problem that monitoring and control system has error alarm and error power off due to frequency signal transmission mode of mine-used analog sensor is interfered by outer interference, the paper analyzed transmission performance and interference performance of frequency signal, proposed anti-interference measures such as differential transmission, sine-wave transmission, current transmission, bus transmission and reducing transmission frequency, and indicated CAN bus with multi-host would be development trend of signal transmission mode of mine-used sensor.
