4D时移高密度遥测系统的研究与应用OA

High-density electrical method is one of the most widely used techniques in engineering geophysics.With the development and application of technologies such as the internet,cloud computing,internet of things and 4G/5G mobile communications,traditional high-density measurement methods can no longer meet customers"demands for instrument intelligence and multi-functionality.Therefore,4D time-shift high-density telemetry system was developed based on the current domestic engineering exploration and environmental monitoring requirements.This system is a new generation high-density DC electrical instrument integrating full waveform current and potential acquisition,high-power control,embedded operating system,time-shift monitoring,remote control and cloud storage.The system is highly adaptable and has low environmental requirements.It can obtain large amounts of high-quality raw data in various complex field environments,and can be widely used in geological disaster monitoring,foundation evaluation,environmental monitoring,fracture leakage monitoring and other fields.Currently,4D time-shift high-density system has been used for fracture leakage monitoring at sites such as Longmen grottoes,Dazu rock carvings and Leshan giant buddha,achieving good results and providing a scientific basis for the subsequent repair of fractures.
