本文主要介绍了一种适用于中小型煤矿安全生产与监测设备的设计方案。该设备能够实时采集、监测井下工作面的瓦斯浓度、一氧化碳浓度、风速、压力、温度等重要数据和风机、水泵、绞车、电机的开停状态,具有对交流电源的过压、失流、缺相及各种异常、危险情况报警的功能。另外,还具有对班次产量的统计,数据存储功能。系统采用低压电力线载波通讯及GSM/GPRS无线通讯技术进行数据的传输。 This article mainly introduces a kind of design scheme suitable for small and medium coal mine safety production and monitoring equipment. The device can collect and monitor real-time data such as gas concentration, carbon monoxide concentration, wind speed, pressure, temperature and other important data of the downhole face and fans, pumps, winches, motors open and stop state, with AC power over-voltage, Phase and all kinds of abnormal, dangerous situation alarm function. In addition, there is also statistics on the shift production, data storage capabilities. System uses low-voltage power line carrier communication and GSM / GPRS wireless communication technology for data transmission.
