Measuring system and method for measuring the coordinates of the point to be measured with misaligned wires

Abstract

The invention relates to a measuring system and method for measuring coordinates of points to be measured without traverse alignment. The method includes the steps that coordinate values of the points to be measured are determined according to coordinate values of known measuring points, a common point is selected, and the known measuring points and the points to be measured are arranged at the two sides of the common point respectively; a triangle is formed by the common point and the known measuring points; a triangle is formed by the common point and the points to be measured; coordinate values of the common point are determined through the coordinate values of the known measuring points; the coordinate values of the points to be measured are determined according to the coordinate values of the common point. Neither a plumb bob nor alignment is needed in the method for measuring the coordinates of the points to be measured without traverse alignment, the defect that alignment errors exist in a conventional downhole traverse survey method is overcome, high-precision measurement of large engineering breakthrough and equipment installation is ensured, unnecessary engineering waste is directly saved for downhole production, measurement cost is reduced, and measurement accuracy and efficiency are improved.

Description

technical field [0001] The invention relates to a geological surveying method, in particular to a surveying system and a surveying method for measuring the coordinates of a point to be measured with a misaligned wire. Background technique [0002] Traverse survey refers to the operation of measuring the length, rotation angle and elevation of the wire, and calculating the coordinates. [0003] Select a series of points on the ground to form a polyline, set up a station on the points, and then measure the horizontal position of these points by measuring the edge and angle. Traverse measurement is a common method for establishing control points in engineering survey. [0004] The polyline formed by the station points is called a traverse, and the station points are called traverse points. Measure the distance between every two adjacent points and the included angle between adjacent sides on each traverse point, start from the coordinates and azimuth of a starting point, use ...

Problems solved by technology

However, sometimes the wind speed in the underground roadway is very high, which is very unfavorable to the centering of the instrument. Even if the centering is affected by the wind speed, the measurement accuracy is not high, the centering error is large, and the measured coordinates of the points to be measured are inaccurate, resulting in the established underground plane The network is not accurate, which will eventually lead to problems when using the downhole plane network to guide underground development, mining, cutting and recovery, such as deviations in the mining position, etc. Minor deviations may cause serious engineering waste and greatly increase labor costs.
