Abstract

The invention relates to a direct current electrical resistivity imaging device and a distributed measurement station. The imaging device comprises a host, multiple distributed measurement stations and a main cable. The host and the distributed measurement stations are connected together through the main cable. Each distributed measurement station comprises multiple electrode cables. Multiple electrode joints are arranged on the electrode cables. According to the invention, by use of the combination scheme of mixing the distributed scheme and the centralized scheme, the host and the measurement stations are connected in a distributed manner and communicate with each other in a bus manner; one main station can be serially connected with and control multiple measurement stations, so expandability of the whole set of the device is ensured; centralized control is achieved between the measurement stations and the electrodes, so efficiency of the measurement work is improved; and in the system, common electrodes are used as grounding bodies, and no electronic parts are arranged on the electrodes, so cost is remarkably reduced and working reliability is improved.

Description

technical field [0001] The invention relates to a DC resistivity imaging device and a distributed measuring station thereof, belonging to the field of DC resistivity imaging. Background technique [0002] In the fields of geological survey, resource exploration, engineering quality inspection and monitoring, DC resistivity imaging is a commonly used geophysical method. The basic principle of DC resistivity imaging is to arrange a series of electrodes inside or around the detection area to form an observation system, complete several power supply-measurement cycles, record relevant data, and finally use a certain imaging algorithm to obtain the resistance in the detection area rate distribution. In a single measurement, according to a certain measurement mode, select the power supply electrodes A, B and the measurement electrodes M, N, apply a certain voltage between A and B, measure and record the supply current I between A and B and between M and N The measurement voltage...
