针对煤巷工作面粉尘治理的问题，设计煤巷高压喷雾除尘自动控制系统。粉尘传感器及时监测工作面煤矿粉尘浓度，设置上限、下限两个动作阈值，采用PIC16 F877处理器控制电磁阀打开和关断高压供水管路喷雾装置，并可通过热释电红外传感器检测人体信号，在矿工通过喷雾区域时暂时停止喷雾。该系统实现喷雾过程自动控制，高压喷雾装置有效地降低了工作面粉尘浓度，提高了除尘效率，改善了矿工工作环境。

It is a serious problem that the dust pollution at driving face in coal road.The automatic control system of dust suppression by high-pressure spray in the coal roadway is designed.Dust sensor is monitoring dust concentration of working face in real time.The PIC16F877 processor is used to control the electromagnetic valve to open and shut off the spray device of high-pressure water supply pipeline according to the upper limit and lower limit thresholds of dust concentration.When the miners go through the spray zone human body signal is detected by pyroelectric infrared sensor and the spray stops tempora-rily.The automatic control system of high -pressure spray and dust reduction has significant effect in dust concentration and improves the efficiency of reducing dust and the environment of the coal face.
