Description
Technical field
The invention belongs to engineering measuring technology field, more particularly to a kind of measuring method of total powerstation height of instrument.
Background technology
The measurement of current total powerstation instrument height is to use 2m tape measures, needs two people to coordinate, after instrument centering is flattened, from
Survey station point amount obtains height of instrument to instrument height mark, then by the conversion of certain triangle.The method measurement error is larger, and artificially
Factor influence is big, it is impossible to meet the requirement of engineering survey high-acruracy survey.
The content of the invention
It is an object of the invention to：A kind of error of present invention offer is small, accuracy is high, total powerstation instrument height easy to operate
The measuring method of degree.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of measuring method of total powerstation height of instrument, comprises the following steps：Step 1: on the ground of survey station point A certain distances
On select an observation station B, survey station point A and observation station B are mounted with the prism erected with prism bracket, frame are had into the complete of foot stool respectively
Instrument of standing is placed in survey station point A, the side of 2 lines of observation station B, and adjustment total powerstation, survey station point A, 3 lines of observation station B exist
Projection forms equilateral triangle on horizontal plane；Step 2: after total powerstation is adjusted, using total powerstation Opposite side survey function, difference
The prism for aiming at survey station point A and observation station B is measured, and determines the horizontal range D and discrepancy in elevation h between survey station point A and observation station BAB；
Step 3: total powerstation is placed at survey station point A, and centering is flattened, and aims at observation station B, using just, reversing face observation is averaged
The horizontal line and vertical angle α formed by observation station B at total powerstation center are passed through in method observation；Step 4: can be obtained by calculation formula
To height i=h of total powerstation instrumentAB—D*tanα.The calculation formula is tan, is calculated further according to schematic diagram and obtains complete
Stand the height of instrument instrument.
Preferably, in step one, the observation station B and survey station point A distances are 5~10m.
Preferably, requiring the prism and prism branch of survey station point A and observation station B placements in step 2 and step 3, observation
The height that frame is added up keeps identical.
In summary, the present invention has the positive effect that as a result of such scheme：The present invention using survey station point and
The difference in height and horizontal range of observation station, survey station point dispose instrument, observe observation station vertical angle, using vertical angle, 2 points
The relation of horizontal range and the discrepancy in elevation, obtains total powerstation trunnion axis to the distance i.e. total powerstation height of instrument of survey station point.The present invention's
Principle is simple and clear, and measurement process does not need additional means, and error is smaller, and human factor influence is small, and accuracy is high, disclosure satisfy that
Engineering survey high-acruracy survey requirement, and it is easy to operate, be easy to grasp, be easy to engineering application, be easy to large-scale promotion.
Brief description of the drawings
Fig. 1 is the horizontal range and discrepancy in elevation schematic diagram that the present invention observes 2 points of A, B using total powerstation；
Fig. 2 be the present invention by total powerstation be placed in survey station point A at observation by total powerstation center horizontal line and observation station B into
Vertical angle α schematic diagrames.
In accompanying drawing：1- total powerstations；2- foot stools；3- prisms；4- prism brackets.
Embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described,
Obviously, described embodiment is only a part of embodiment of the invention, rather than the whole embodiment of the present invention.
Embodiment 1
As depicted in figs. 1 and 2, a kind of measuring method of total powerstation height of instrument, comprises the following steps：Step 1: in survey station point A
An observation station B is selected on the ground of certain distance, survey station point A and observation station B are mounted with the prism erected with prism bracket 4 respectively
3, the total powerstation 1 that frame has foot stool 2 is placed in the side of survey station point A, 2 lines of observation station B, adjustment total powerstation 1, survey station point
A, 3 lines of observation station B project to form equilateral triangle in the horizontal plane；Step 2: after total powerstation 1 is adjusted, using whole station
The Opposite side survey function of instrument 1, the prism 3 that survey station point A and observation station B is aimed at respectively is measured, determine survey station point A and observation station B it
Between horizontal range D and discrepancy in elevation hAB；Step 3: total powerstation 1 is placed at survey station point A, and centering is flattened, and aims at observation station B,
Using just, the method observation that is averaged of reversing face observation is by vertical angle α formed by the horizontal line and observation station B at total powerstation 1 center；
Step 4: calculating the height i=h for obtaining the instrument of total powerstation 1 by tan and Fig. 1 and Fig. 2AB—D*tanα。
Preferably, in step one, the observation station B and survey station point A distances are 5~10m；In step 2 and step 3, see
Require that survey station point A is identical with the height holding that the prism 3 and prism bracket 4 that observation station B is disposed are added up during survey.
In summary, the present invention disposes instrument using survey station point and the difference in height and horizontal range of observation station in survey station point,
The vertical angle of observation station is observed, using the relation of vertical angle, the flat distance of WAWQ and the discrepancy in elevation, total powerstation trunnion axis is obtained to survey station
The distance of point is total powerstation height of instrument.The principle of the present invention is simple and clear, and measurement process does not need additional means, error compared with
Small, human factor influence is small, and accuracy is high, disclosure satisfy that the requirement of engineering survey high-acruracy survey, and it is easy to operate, be easy to the palm
Hold, be easy to engineering application, be easy to large-scale promotion.
