Description
Technical field
The present invention relates to field of measuring technique, the especially high acquisition of total powerstation instrument.
Background technology
Total powerstation, i.e. whole station type electronic distance meter（Electronic Total Station）, it is that a kind of collection is light, mechanical, electrical
The high-tech measuring instrument being integrated, is collection horizontal angle, vertical angle, distance（Oblique distance, it is flat away from）, vertical survey function in one
Instrument of surveying and mapping system.Optical circle is changed to optoelectronic scanning scale by electronic theodolite compared with micrometer instrument, by artificial optics
Micrometer reading instead records and shows automatically reading, makes angle measurement simple operation, and can avoid the generation of error in reading.Because of it
Once placement instrument can be completed all to measure work on the survey station, so referred to as total powerstation.It is widely used in large-scale on the ground build
Build and precise engineering survey or the deformation monitoring field such as construction of underground tunnel.
Total powerstation has angular surveying, distance（It is oblique distance, flat away from, height difference）Measurement, three-dimensional coordinate measurement, traverse survey, friendship
Can the multiple use such as one-point measurement and setting out survey.After built-in special-purpose software, function can also be expanded further.
Instrument higher position is to set up the ground reference point of total powerstation to the height of instrument eyepiece central point.Total powerstation is related to instrument
The high basic operation of device has range measurement and measurement of coordinates with application method, is described below respectively.
1. range measurement
（1）Prism constant is set
Prism constant must be inputted before ranging in instrument, instrument can be automatically to institute's ranging from correcting.
（2）Atmospheric correction value or temperature, atmospheric pressure value are set
The spread speed of light in an atmosphere can change with the temperature and air pressure of air, and 15 DEG C and 760mmHg are that instrument is set
One standard value, atmospheric correction at this time is 0ppm.During actual measurement, can input temp and atmospheric pressure value, total powerstation can calculate greatly automatically
Gas corrected value（Also atmospheric correction value can be directly inputted）, and distance measurement result is corrected.
（3）Measuring appratus is high, prism is high and inputs total powerstation.
（4）Range measurement
Target prism centers are sighted, press ranging key, range measurement starts, and ranging show oblique distance, puts down away from, height difference when completing.
The distance measurement mode of total powerstation has fine mode, tracing mode, three kinds of bigness scale pattern.Fine mode is most common survey
Away from pattern, time of measuring about 2.5S, minimum unit of display 1mm；Tracing mode, is usually used in continuous when tracked mobile target or setting-out
Ranging, minimum display are generally 1cm, each ranging time about 0.3S；Bigness scale pattern, time of measuring about 0.7S, minimum display are single
Position 1cm or 1mm., can be by distance measurement mode in range measurement or measurement of coordinates（MODE）Key selects different distance measurement modes.
2. measurement of coordinates
（1）Set the three-dimensional coordinate of survey station point.
（2）The horizontal limb reading of apparent direction is its azimuth after setting the coordinate of backsight point or setting.When setting backsight
During the coordinate of point, the azimuth of apparent direction after total powerstation can calculate automatically, and after setting apparent direction horizontal limb reading as it
Azimuth.
（3）Prism constant is set.
（4）Atmospheric correction value or temperature, atmospheric pressure value are set.
（5）Measuring appratus is high, prism is high and inputs total powerstation.
（6）Target prism is sighted, presses measurement of coordinates key, total powerstation starts ranging and calculates the three-dimensional coordinate of display measuring point.
It can be seen from the above that total powerstation instrument height is very important underlying parameter, the high precision of instrument is adjusted the distance with coordinate etc.
The measurement accuracy of fundamental influences very big.
The high measuring method of existing instrument mainly has the following two kinds.
（1）Steel tape mensuration
Most traditional instrument high measurement method.Instrument height is vertical range of the measurement control point to centre, directly measure because
It is not flat relation of plane, absolute being error, in addition steel tape measurement error is larger.
（3）Laser optical method
The amount of laser light point function having using instrument itself measures, although laser measurement precision is all higher than above two method,
Because hot spot is beaten inside crosshair rather than datum mark peak, systematic error is brought, overall measurement accuracy is restricted.
The measurement accuracy of above measuring method is grade, the inapplicable occasion for needing fine instrument high parameter.
The content of the invention
The technical problems to be solved by the invention are how to accurately acquire total powerstation instrument height.
