【摘要】 通过地下水位变化对滑坡等地质灾害的影响研究,设计了一种高精度地下水位监测仪器。仪器采用静压力式水位传感器获取地下水位信息,通过精密I/V转换、高精度A/D转换及高稳定性基准电压,并配合曲线拟合方法,实现了地下水位信息的高精度采集,误差≤1 mm.在实际应用中,仪器突出了精度高、性能稳定、体积小、安装灵活、操作方便等优点,对各类监测井具有很强的适应性,适合用于地质灾害监测。更多还原

【Abstract】 Through studying the change of groundwater on the influence of the geological hazards,such as landslide,a high precision groundwater level monitor was designed.The monitor took advantage of static-pressure water level sensor to get ground-water level information.By means of sophisticated I/V conversion,high precision A/D conversion,high stability reference voltage and cooperating with curve fitting method,it realized the high precision collection of groundwater level information,and the system error was less than 1 mm.In the actual application,the instrument highlighted its advantages such as high precision,stable performance,small volume,installation flexible,convenient operation,etc.The monitor can be applied to all kinds of monitoring wells very well,and used in geological disaster monitoring.更多还原
