It is single, it saves and calculates and chart the time, error rate is low.
Detailed description of the invention
Fig. 1 is a kind of flow diagram of tunnel Trigonometric Leveling provided by the invention.
Specific embodiment
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described, it is clear that described embodiment is a part of the embodiments of the present invention, without
It is whole embodiments；Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Every other embodiment obtained is put, shall fall within the protection scope of the present invention.
Refering to fig. 1, Fig. 1 is a kind of flow diagram of tunnel Trigonometric Leveling provided by the invention.This method
The step of include:
S110: being arranged total station in preset measuring point, and acquires total station in the measurement data of default measuring point acquisition.
S120: the data based on acquisition, according to the elevation of the grid DEM whole measuring point of known backsight point；Wherein, if
Know that backsight point is top plate point, then the height of site=known backsight point height-measuring point is away from rising-total station height difference registration；If after known
Viewpoint is bottom plate point, then the height of site=known backsight point height+measuring point is away from bottom height-total station height difference registration.
S130: if the measuring point elevation being calculated is identical as known backsight point, being identified as backsight point, according to being calculated
The height of site calculate high, the measuring point floor elevation=height of site+total station of observing identical measuring point bottom plate with next stop survey station
Height difference registration-measuring point is away from bottom height.
S140: the top bottom for finding out each measuring point according to each measuring point elevation is high, each measuring point top plate elevation=each height of site+whole station
Instrument height difference registration+away from rising；Each measuring point floor elevation=each height of site+total station height difference registration.
Wherein, total station height difference registration are as follows: tan(90 °-vertical angle registration) × it is flat away from absolute value).
It wherein, further include according to each measuring point after the high step in the top bottom for finding out each measuring point according to each measuring point elevation
The step of pushing up bottom height production CAD diagram.
Wherein, include: according to the step of top bottom height production CAD diagram of each measuring point
It is set to (0,0) with known backsight point coordinate, flat by backsight point to survey station acquires the X-coordinate of measuring point, root away from add up
Flat away from each measuring point X-coordinate is acquired according to each measuring point, each measuring point top bottom height-most starts the result of backsight point height as Y-coordinate, each
Measuring point top plate point coordinate and bottom plate point coordinate；
It exports CAD to order at figure, each measuring point XY coordinate is connected in turn using CAD order " _ line ", and is closed, generate
Tunnel sectional view, and marked resulting each measuring point top bottom elevation near each measuring point using order " _ text ".
When carrying out triangulated height calculating, need to select to calculate type, it, need to be by measuring sequence the number of each point when input data
According to sequentially inputting, centre separates that (the vertical angles every minute and second that Data Processing in Rigorous Trigonometric Leveling is filled in also is separated with space, institute with space
Filling out vertical angle is the angle after being averaged less than 180 °), space quantity that it doesn't matter, but it is intermediate there can be no failing to fill in, it puts down away from backsight side
To being negative, preceding apparent direction is positive.Measuring point need to be filled out if you need to calculating the height of site only as survey station, be put down away from=0, height difference=0, vertical angle=0
00 00, it is then total station top bottom height away from top bottom.Originate point number, elevation is known point number and elevation.
Click " file " --- the altitude data acquired can be saved as text document by " saving calculated result ".It calculates
Input data can import ready-made data as required, can also click " editor " --- and " being manually entered " is manually entered,
Input survey station, measuring point number, it is flat away from, away from top, the bottom of away from, ordinary trigonometric leveling inputs height difference, Data Processing in Rigorous Trigonometric Leveling input
Then vertical angle after average clicks " starting to calculate elevation ", computer can be obtained by each measuring point top bottom height, and generate
CAD is ordered at figure, and generation is clicked by right key " Quan Xuan " " duplication " at figure order, pastes in CAD software, will be immediately generated
Tunnel sectional view, and mark top bottom elevation.
The sectional view of generation is defaulted as measuring from West to East, can be used in CAD software if direction is inconsistent
Rotation and image feature are adjusted.
In order to improve calculating and at figure efficiency, error rate is reduced, oneself design software imports measurement data in software,
It clicks to calculate and can be instantly obtained each measuring point top bottom elevation, while the CAD order of generation being input in CAD software, can stand
Tunnel sectional view is generated, and the top bottom for having marked each point is high.Software can carry out secondary development according to oneself demand simultaneously.
It is different from the prior art, tunnel Trigonometric Leveling of the invention is using computer to total station survey data
Batch processing is carried out, ordinary trigonometric leveling can be carried out and Data Processing in Rigorous Trigonometric Leveling calculates, each measuring point top is calculated
Floor elevation；It is flat away from CAD is automatically generated into figure order using obtained roof and floor elevation and each measuring point, it imports in CAD software certainly
It is dynamic to generate tunnel sectional view, and roof and floor height value has been marked automatically.By means of the invention it is possible to save human resources, and operate letter
It is single, it saves and calculates and chart the time, error rate is low.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
