【摘要】：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。
[Abstract]:In order to improve the level of hydrological monitoring and water hazard prediction of underground water in coal mine, a real-time monitoring and warning system of underground water in coal mine based on intelligent water level meter is designed.In this system, the metal probe of water sensitive sensor is used to judge whether the intelligent water level meter is in the aquifer or not. When the water level falls below the intelligent water level meter, the intelligent water level meter can be automatically put into the water, thus avoiding the generation of false data.The pressure sensor is used to obtain the water pressure data, and the data are fitted and analyzed by the upper computer software, and then the water level is calculated.The test results show that the system works stably, the measurement error of aquifer water level is less than 2 cm, and the water level change can be predicted within 5 seconds.
