Fine movement array configuration device

Abstract

A fine movement array configuration device comprises a fixed support, a rotary platform and a distance measurement device. The rotary platform comprises a circular skeleton, an equilateral triangle skeleton 1 and an equilateral triangle skeleton 2; the equilateral triangle skeleton 1 is internally connected with the circular skeleton, and the equilateral triangle skeleton 2 is internally connected with the equilateral triangle skeleton 1; the rotary platform is fixed on the fixed support; and the distance measurement device comprises a plurality of laser distance measurement devices arranged on the circular skeleton at regular intervals. When usage, the fine movement array configuration device does not need to calculate the position coordinates of each detection point in advance, cannot be basically influenced by weather phenomena such as barriers, wind and the like, is higher in configuration precision and high in configuration efficiency, and only needs one person to locate and configure detectors without the limitation of the configuration scale.

Description

technical field [0001] The invention relates to the technical field of geophysical exploration, in particular to a micro-motion-based exploration method and the layout of a micro-motion observation system. Background technique [0002] Fretting is a kind of geophysical prospecting method. Fretting comes from various activities of nature and human beings; wind, tides and volcanic activities in nature will produce vibrations; human trains, cars, and machine operations will produce vibrations, and even human walking will also produce vibrations. All these vibrations propagate far away in the form of body waves and surface waves, and the energy of the surface waves accounts for more than 70% of the total energy of the signal. The micro-motion-based exploration method is to extract the dispersion information of the surface wave from the collected micro-motion data, and infer the velocity structure of the underground medium. [0003] The micro-motion observation system is a syst...

Problems solved by technology

When deploying micro-motion arrays in such a large-scale range, using GPS for positioning can also meet the requirements, but when deploying small-scale engineering-type micro-motion arrays, the deployment time of each deployment point is measured in minutes (large scales are measured in minutes) Hour meter), if you still use GPS for positioning, you need to go through a series of operations such as GPS star search, X coordinate position correction, Y coordinate position correction, etc., which will consume a lot of time and increase the relative error of GPS in a small scale. Accuracy decreases in large, cloudy skies or with obstacles in the sky
