Description
Technical field
The present invention relates to field of measuring technique, the especially high measurement of total powerstation instrument.
Background technology
Instrument higher position is to set up the ground reference point of total powerstation to the height of instrument eyepiece central point.Total powerstation instrument is high
Precision directly determines the precision of surveyed coordinate elevation, and the influence for whole measurement accuracy is very big.
（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.
（2）Suspension surveying method
1. total powerstation is erected at distance measurement object remotely so that the vertical angle of survey station telescope to outstanding high point is less than 45
Degree.Because if vertical angle is larger, the altitude difference error that trigonometric function calculates is larger.2. projected in outstanding high point on ground
Datum mark erects prism.The line of survey station and ground reference point, the preferably trend with Suspension surveying object intersect vertically.3. enter
The Suspension surveying program of total powerstation, inputs prism height, and alignment prism simultaneously presses measurement key, observation survey station and datum mark prism away from
From.4. unclamping the braking of telescope vertical direction, sight the outstanding high point above prism, instrument can with the rotation of vertical circle,
Show corresponding ground point to the height difference of outstanding high point.This measuring method operation sequence is cumbersome, and error mainly includes Laser Measuring
The error that prism away from error, trigonometric function error and introduction is brought.
（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.In order to
Meet some elevation high-acruracy survey occasions, it would be desirable to be able to which high accuracy, easily measure the high apparatus and method of total powerstation instrument.

Embodiment
Embodiment 1, as illustrated in the accompanying drawings from 1 to 3.
There is the total powerstation of instrument high precision measurement, including total powerstation, telescopic rod and displacement meter, telescopic rod are vertically pacified
Under the pedestal of total powerstation, telescopic rod is hollow structure, and displacement meter is installed on the outside of telescopic rod.Preferably, telescopic rod is by two
Section quarter butt concatenation forms.The reasons why only two sections of quarter butt concatenations is that first, telescopic rod can be highly transferred to 80mm by two sections of concatenations
Hereinafter, general enough to use, secondly, multistage concatenates the verticality for being more difficult to guarantee its junction, can bring the measurement error of bigger.
Preferably, the cross section of telescopic rod is equilateral triangle.The reasons why telescopic rod cross section is equilateral triangle is, in materials and dosage phase
With in the case of, the polygonized structures such as triangle is more circular are more stable, are not likely to produce Bending Deformation.Preferably, displacement is calculated as mangneto
Telescopic displacement meter, its both ends are separately mounted to telescopic rod upper and lower ends.
Magneto strictive sensor is the high accuracy displacement sensor developed using " magnetostriction principle ", is connect using non-
Measurement method is touched, due to the reason such as rubbing, wearing the service life of sensor will not be caused to reduce.Its good environment adapts to
Property, reliability and stability, it is extremely easy to use, have compared with the products such as conductive rubber, LVDT, resistor type displacement sensor bright
Aobvious advantage.Its output signal is a real absolute position output, rather than ratio or need again enhanced processing
Signal, so equally need periodically to mark there is no the situation of signal drift or variate, therefore not necessarily like other displacement sensors again
And maintenance；Exactly because its output signal is absolute figure, if so power interruptions reclosing will not be to data receiver structure
It is problematic, more zero-bit need not be returned to again.The main reason for selecting magnetostrictive displacement meter is that the optional 50mm of its range is arrived
8000mm, 1000mm or so is chosen in the suitable this case of range ability, while its precision may be up to 0.002%, be converted to
The measurement error of 1000mm is 1000 × 0.002mm=0.00125mm, enough for general instrument high measurement accuracy.It is preferred that
Ground, telescopic rod bottom are substrate, it is installed on telescopic rod lower end.Preferably, substrate is clear glass cylinder shape substrate.It is preferred that
Ground, substrate are detachable.Preferably, alignment laser is vertically mounted under pedestal, in telescopic rod.Laser-light transparent glass
Glass substrate carries out centering with ground reference point, avoids the presence of telescopic rod to the influence of laser alignment.Preferably, telescopic rod epimere
The cross section of quarter butt is more than hypomere quarter butt, there is screens screw on epimere quarter butt, and telescopic rod screws screens screw after shortening will two
Section quarter butt position is fixed.The total powerstation application method：A. total powerstation is set up, telescopic rod is in shortening state at this time：B. centering：c.
It is thick flat：D. essence is flat：E. instrument instrument height is measured, stretchs out telescopic rod, its bottom is touched terrestrial reference, record displacement meter is shown
Reading.
To avoid the installation of telescopic rod from influencing the centering leveling of total powerstation, telescopic rod is after total powerstation erection, centering leveling
Before be installed under total powerstation substrate, or be fixedly mounted always with total powerstation., must when unscrewing screens screw and stretching out telescopic rod
Light hand operation, must not touch total powerstation.When telescopic rod is stretched out to close to ground reference point, the non-shadow of confirmation operation should be examined
The centering leveling of total powerstation is rung, otherwise should stop stretching out for telescopic rod, again centering leveling.In order to further avoid hand from operating
Influence, also it is remote-controlled control unclamp positioner, appoint a telescopic rod hypomere quarter butt drop to ground reference point by free gravity.
