Abstract

The invention discloses a total station networking measurement method of a large-scale structural component, and belongs to the technical field of industrial measurement. The measurement accuracy in the prior art is low. The total station networking measurement method comprises the steps of before measurement is carried out, enabling a main station total station and an auxiliary station total station to be arranged on the two sides of the to-be-measured large-scale structural component, determining a main station user coordinate system, determining a plurality of reference points at the positions, located between the main station total station and the auxiliary station total station, of the periphery of the large-scale structural component, enabling the reference points to be brought into the main station user coordinate system, enabling six or more of the reference points to serve as station setting reference points, measuring the coordinate values of the station setting reference points, enabling the station setting reference points to be capable of being simultaneously measured by the auxiliary station total station, establishing an auxiliary station user coordinate system according to the station setting reference points, enabling the main station total station and the auxiliary station total station to respectively measure and record the coordinate values of the other reference points, and obtaining conversion parameters according to a parameter coordinate conversion equation. When measurement is carried out, data measured by the main station total station direct serve as measurement results, data measured by the auxiliary station total station serve as measurement results after coordinate conversion is carried out, and measurement on the whole large-scale structural component is completed.

Example Embodiment

[0024] Its specific scheme of the method for measuring large structural parts by total station network of the present invention is as follows, see image 3 as shown,
[0025] (1) Before measurement
[0026] Set the main station total station 1 and the auxiliary station total station 2 on both sides of the large structural part 3 to be measured; determine three measuring points on the large structural part 3, and place a positioning prism, according to the three measuring points and passing Determine the user coordinate system of the main station by the method of surface-line-point; determine several reference points q between the total station 1 of the main station and the total station 2 of the auxiliary station, and around the large structural part 3 1...q n , and place the positioning prisms one by one, the reference point q 1...q n Include the master station user coordinate system, use six or more of them as the reference points for setting up stations, and measure their coordinate values, and the reference points for setting up stations can be measured by the auxiliary station total station 2 at the same time; The reference point is to establish the user coordinate system of the auxiliary station through the coordinate orientation method; the total station 1 of the main station and the total station 2 of the auxiliary station respectively measure and record other points other than the reference point for setting up the station, which can be controlled by the total station 1 of the main station and the total station 2 of the auxiliary station. The reference point coordinates measured by station total station 2 at the same time, the coordinate values ​​of the master station user coordinate system and the auxiliary station user coordinate system coordinate values ​​of these reference points are substituted into the seven-parameter coordinate conversion equation to obtain the conversion parameters: coordinate translation amount X 0 , Y 0 ,Z 0 , Coordinate rotation ω x , ω y , ω z , Scale coefficient m.
[0027] (2) When measuring
[0028] The master station total station 1 and the auxiliary station total station 2 respectively measure the measurement points on the large structural parts 3 that can be measured respectively, wherein the measurement data of the master station total station 1 is directly used as the measurement result; the auxiliary station total station 2 Measurement data (X 1 , Y 1 ,Z 1 ) is transformed into the coordinate value (X 2 , Y 2 ,Z 2 ) becomes the measurement result, the total station 1 of the main station and the total station 2 of the auxiliary station jointly complete the measurement of the large structural part 3 as a whole.
[0029] X 2 Y 2 Z 2 = X 0 Y 0 Z 0 + 0 - Z 1 Y 1 Z 1 0 - X 1 - Y 1 X 1 0 ω x ω y ω z + m X 1 Y 1 Z 1 + X 1 Y 1 Z 1 - - - ( 4 )
[0030] Where: X 1 , Y 1 ,Z 1 is the coordinate value of the measurement point in the user coordinate system of the auxiliary station, X 2 , Y 2 ,Z 2 is the coordinate value of the measuring point in the user coordinate system of the master station, X 0 , Y 0 ,Z 0 is the coordinate translation, ωx, ωy, ωz are the coordinate rotation, and m is the scale coefficient.
