Four-dimensional direct-current electric process monitoring system on basis of remote control and inversion method

Abstract

The invention discloses a four-dimensional direct-current electric process monitoring system on the basis of remote control and an inversion method. The four-dimensional direct-current electric process monitoring system and the inversion method have the advantages that monitoring procedures for data acquisition instruction transmission, data inversion and interpretation processing, visual imagingfeedback and the like are executed at remote control ends, accordingly, data can be quickly inverted and interpreted, and development and evolution characteristics of monitoring objects can be accurately judged by the aid of merits of remote expert consultation; time+space four-dimensional models can be built by the aid of four-dimensional inversion algorithms, four-dimensional linear equation sets and visual imaging can be solved, and accordingly time-dependent continuously variable characteristics and laws of electric abnormal bodies in monitored regions can be truly reflected to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of geophysical monitoring, and relates to a direct current method geophysical monitoring device, a monitoring method and a data processing method, in particular to a remote control-based four-dimensional direct current method monitoring system and an inversion method. Background technique [0002] Geophysical monitoring has been widely used in many natural hazards, environmental, hydrological and engineering problems. In particular, since the resistivity of subsurface media is easily affected by the movement of conductive or resistive fluids, the DC resistivity monitoring method has shown significant advantages in related fields involving groundwater movement or migration, and has been successfully applied to saltwater intrusion and pollutants in aquifers. Migration process monitoring, dam leakage monitoring, hydrogeological characteristics analysis, tunnel water inrush disaster monitoring, etc. [0003] Fo...

Problems solved by technology

[0004] However, the above hardware or instrument improvements are still based on the existing two-dimensional or three-dimensional electrical instruments and data processing methods, that is, a series of discrete two-dimensional or three-dimensional space observations are used to approximately replace four-dimensional space-time monitoring, and no real four-dimensional The acquisition strategy does not establish the relationship between historical observation data and models and dynamically updated observation data and models from the true four-dimensional dimension, lacks an effective combination of space and time, has low temporal and spatial resolution, and responds to rapid changes in underground media and imaging lag
