煤矿地下水实时跟踪监测预警系统设计

Design of real-time tracking monitoring and early warning system for coal mine groundwater

为提高煤矿地下水水文监测和水害预测水平,设计了一种基于智能水位仪的煤矿地下水实时跟踪监测预警系统。该系统采用水敏传感器的金属探针判断智能水位仪是否在含水层中,当水位下降至低于智能水位仪时,可将智能水位仪自动下放入水,从而避免产生伪数据;采用压力传感器获取水压数据,并通过上位机软件对数据进行拟合分析,进而计算出水位。测试结果表明,该系统工作稳定,对含水层水位的测量误差不超过2cm,且能够在5s内对含水层水位突变进行预警。

In order to improve hydrological monitoring of coal mine groundwater and water disaster prediction level,a real-time tracking monitoring and early warning system for coal mine groundwater based on intelligent water level meter was designed.The system uses metal probes of a water sensor to judge whether the intelligent water level meter is in aquifer,and downs the intelligent water level meter into water automatically when water level drops below the intelligent water lever meter,so as to avoid pseudo data.The system obtains water pressure data through a hydraulic sensor,and uses upper computer to fit and analyze the data,so as to calculate water level.The test results show that the system can run stably and early warn water level mutation of aquifer in 5s,whose measurement error of water level is not more than 2cm.
