摘要: 为了提高煤矿安全监控系统对瓦斯传感器的供电距离,从分析对传感器的供电方式着手,对提高输出电压、降低传感器工作电压和减少线缆耗损等方法进行讨论,根据现场实测数据,提出了确保瓦斯传感器在超过标准要求的供电距离时,依然可以正常工作的建议。Abstract: In order to extend the power supply distance from coal mine safety monitoring system to gas sensor,this paper discussed the method of increasing the output working voltage,decreasing the sensor working voltage,reducing cable loss through the analysis of the sensor power supply.According to the measured data,the paper put forward the suggestion of normal operation when the power supply distance of gas sensor exceeded the standard requirements.
