Abstract: Aiming at the factors of the complex geographical environment and multiple water disasters of the underground coal mine, a modern GPRS wireless communication technology is applied to the coal mine hydrology monitoring system. A new intelligent telemetry system was designed. The underground water level and temperature information are collected by means of the high?precision water temperature and water pressure sensors, processed with the low?power consumption chip P89LPC936 further, and transmitted to the upper computer by mean of the mode of GPRS wireless communication. The upper computer can display the water level, water temperature and other information in real time to realize the wireless monitoring of the mine hydrology information. The experimental results show that the system has high accuracy and stability, and can effectively monitor the mine hydrology information in real time.

在煤炭生产的过程中,煤矿安全一直是一项不容忽视的课题。矿井地下水可造成水渗透、管涌等严重水害,而煤矿水文监测系统是预测并监测矿井水害发生的重要手段[1]。在实际的矿用水文监测系统中,如何克服煤矿井下的地理地势环境复杂等因素,实时地对煤矿井下水文信息进行监测显得尤为重要。

近些年来,国内很多煤矿都建立了矿井地下水文监测网络。但是,现有的监测系统传输方式相对落后,监测精度无法满足要求,并且井下地形、地势等条件相对复杂,这给井下布线和监测人员对仪器进行维护带来极大的困难。本文设计了一种高精度无线传输的遥测系统,传感器测量水文信息并通过RS 485总线通信网络传输到单片机中,信息经过处理以后通过GPRS模块MC55无线传输到上位机中,计算机将信息进一步处理并进行存储。……
