Embodiment Construction

[0043] The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments, and the purpose and effect of the present invention will become clearer. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

[0044] 1. System design

[0045] The master-slave random distributed high-density electrical prospecting system of the present invention adopts a wireless telemetry distributed system structure, including a central control unit and a data acquisition unit.

[0046]The central control unit is the brain center and command control center of the entire acquisition system, and is mainly composed of a central control computer (including data acquisition software), a wireless communication control unit, computer peripherals (display, keyboard) and interfaces. The central control computer is controlled by the acqu...

Abstract

The invention discloses a data acquisition method for master-slave random distributed three-dimensional high-density electrical method exploration, which improves and enhances the measurement effect of a random distributed high-density electrical method system during large-depth exploration in a city through a portable and component-type external power supply module. Through the design of the master and slave measuring points, the density of the measuring points is increased, the resolution and the exploration effect are improved, and only the master measuring point is selected for power supply, so that the acquisition workload is reduced, and the number of external power supplies is also reduced. The measurement method is simple, ordered and efficient, continuous rolling measurement of a complete measurement area can be achieved, and the collection efficiency is high.

Description

technical field [0001] The invention belongs to the field of electrical prospecting, in particular to a master-slave random distributed high-density electrical prospecting data acquisition method. Background technique [0002] The high-density resistivity method is an array prospecting method developed on the basis of common electrical prospecting. The traditional high-density electrical method can only use regular grids to arrange electrodes. In cities and other complex environmental conditions, it is difficult to find suitable and regular rectangular areas to regularly arrange electrodes, which seriously restricts the application range of high-density electrical methods. Using a long cable to connect all the electrodes in series, and measuring in series and sequentially according to the position of the electrodes in the cable, is less efficient. Bulky cable connections increase labor intensity, and the existence of obstacles (rivers, large buildings, traffic arteries, etc...
