Design of landslide monitoring instrument based on charge method

利用地球物理中的充电法原理,成功设计了基于充电法原理的滑坡监测仪。监测仪由电极转换模块、信号测量模块、远程传输模块及电源模块四部分组成。微控制器控制电极转换模块将供电电压通过位于井中的供电电极供入地下,信号测量模块完成布设于地面的测量电极之间的电压和供电电流的采集,远程传输模块将采集到的电压值和电流值传输到监控中心,从而实现对滑坡的远程监测。最后给出了野外应用试验,试验结果表明监测仪器能稳定工作。

According to the charge method principle in geophysics, successful designs a landslidemonitoring instrument. The monitoring instrument consists of the electrode conversion module, the signal measurement module, the remote transmission module and the power supply module. The microprocessor controls the electrode conversion module to supply the voltage into the underground through the power supply electrode located in the borehole. And the signal measurement module completes the collection of the voltage which between the measuring electrode placed on the ground, also it collects the supply current. Then the remote transmission module transmits the voltage and the current to the monitoring center to realize remote monitoring of landslide.Finally, this paper presents a field application experiment, and tile test results indicate that the monitoring instrument can stable work.
