Design And Implementation Of The High Density Resistivity Method In Geological Monitoring System Based On LabVIEW

The high density resistivity method is the difference in rock and soil medium conductivity as the foundation,applied field current stable through to the underground,in an array of conduction current distribution in strata exploration method,its application in geological exploration and monitoring and forecasting fields.Based on LabVIEW,a geological monitoring system based on high-density resistivity method is designed and applied to geological monitoring.Specific work is as follows:1?The main part of the geological monitoring system is designed.This part is composed of three parts:power supply,host computer control board and data acquisition card.The power supply for the host power supply,and realize the constant power supply geological monitoring;host control board to achieve power supply and measuring electrodes and the choice of the signal acquisition hardware filtering;data collection data acquisition card,and its speed is transmitted to the host computer2n The system software is written based on LabVIEW language.The software can measure the electrode grounding resistance,configure the measurement parameters,and set the electrode coordinates in the electrode system.In data processing,combined with the advantages of LabVIEW programming language,the collected data is filtered,calculated,displayed,stored,and so on.3?The high density resistivity geological monitoring system design is completed,to test the function of this system,including the host performance test,PC software program running function test,system accuracy and stability test.Through the test and debugging of the system,the performance of the system meets the design requirements.Geological monitoring system developed in this paper can meet the design requirement and different monitoring environment,it's main features are:(1)the power supply electrode,constant voltage power supply using the optional power supply voltage;(2)according to the different needs of the geological monitoring,can realize flexible column electrode array configuration monitoring;(3)the system structure is simple,good sealing performance,waterproof and moisture proof performance better.After the instrument is used repeatedly,the geological monitoring system can realize the monitoring of geological objects using high density resistivity method,and can adapt to various complex geological environment,can work stably for a long time.
