【摘要】：基于三极法研制了分层土壤电阻率在线监测系统,系统主要包括客户端软件、土壤电阻率监测仪和接地极3部分。分层土壤电阻率在线监测系统不但可以单机测量而且还可以形成一个多站点的土壤电阻率监测网络。该系统实现了4个功能:第一,同时测量5个以内不同深度层次的土壤电阻率和接地电阻值;第二,利用GPRS无线传输或串口有线传输实现了长期自动不间断地监测多地点、不同采样周期的土壤电阻率变化规律;第三,可在多种恶劣环境下远程监测不同设备接地装置的接地电阻值;第四,实现了测量数据的实时传送与显示以及对历史测量数据的快捷处理。通过三年的试验表明,该系统可以稳定准确地测量出不同深度层次的土壤电阻率值,测量数据可以精确地反映不同深度层次土壤电阻率的变化规律与温度、降水等气象因素的相关性。
[Abstract]:Based on the three-pole method, a layered soil resistivity on-line monitoring system is developed. The system mainly includes client software, soil resistivity monitor and earth electrode. The layered soil resistivity on-line monitoring system not only can be measured on a single machine, but also can form a multi-site soil resistivity monitoring network. The system realizes four functions: first, measuring the soil resistivity and grounding resistance of five different depth levels at the same time; second, using GPRS wireless transmission or serial cable transmission to realize long-term automatic monitoring of multiple locations. The variation of soil resistivity with different sampling periods; third, the earthing resistance of different equipment grounding devices can be remotely monitored in a variety of harsh environments; fourth, The real-time transmission and display of measurement data and the quick processing of historical measurement data are realized. Three years of experiments show that the system can stably and accurately measure the soil resistivity values at different depth levels, and the measured data can accurately reflect the variation law and temperature of soil resistivity at different depth levels. Correlation of meteorological factors such as precipitation.
