Description
Technical field
The present invention relates to a kind of total powerstation high inclination-angle analysis of measurement errors and correcting methods.
Background technology
Total powerstation carries out underground mapping operation, however technical staff has found in total powerstation application process, when inclination angle is larger
When (according to current empirical value, when inclination angle is more than 20 degree, error is clearly present), such as head sheave chamber is put by rope race and promotes ten
During wordline) there are certain errors for Measurement results, and inspection information, domestic at present there is no relevant treatises, seek advice from some measurements
During expert, the problem of all thinking to be implicitly present in this respect
Invention content
The defects of to overcome the prior art, the present invention provide a kind of total powerstation high inclination-angle analysis of measurement errors and correction side
Method, the technical scheme is that：
Total powerstation high inclination-angle analysis of measurement errors and correcting method, this method use high-low points method, carry out in four steps.
Four steps are specially：
Step (1) selects a measuring point, period 1#, then the in height for the top of the first building main body of h
Three points are chosen on vacant lot before one building, period is respectively 2#, 3#, 4#；The inclination angle of wherein 2# and 1# be 30 degree, 3# and
The inclination angle of 1# is 50 degree, and the inclination angle of 4# and 1# are 70 degree；
Total powerstation is erected on 2#, 3#, 4# by step (2) successively, measures the coordinate of 1# respectively, and by 1# during this
The prism at place from vertical position forward to the position vertical with sight, period 2#, 3#, 4# respectively obtain prism it is vertical when observation
Value and the observation with sight when vertical；
Total powerstation is erected at the top of the second building main body by step (3), and the height of the second building main body is the
The coordinate of 1#, 2#, 3#, 4# are measured, for examining in the 1/2 of one building body height respectively at the top of the second building main body
Nuclear tests data；Ensure that total powerstation is less than 10 degree with 2#, 3#, 4# measuring point inclination angle in this step；
Step (4) is by comparative analysis experimental data, the reason of finding out inclination effect total station survey precision and to measuring
Error is analyzed, and is then corrected, and in the step (4), according to analysis result, prism camera lens should during total station survey
It is adjusted when according to total powerstation sight inclination angle, until measurement result is only correctly when vertical with sight；It is erected when keeping prism
When straight, high inclination-angle measurement is carried out during big vertical survey, when prism camera lens is kept vertical, correcting method is f=3-3*Sin α, α
Represent the inclination angle number of degrees.
It is an advantage of the invention that：It finds out the reason of influencing precision and is rationally evaded, can be improved to a certain extent
Unwrapping wire precision reduces the unwrapping wire error brought by high inclination-angle measurement, and reducing single rope hoist engine may be potentially inaccurate because of unwrapping wire
Cause head sheave installation error.
