Description
Technical field
The utility model is related to the measurement of field of measuring technique, especially total powerstation instrument height.
Background technology
Instrument height is exactly to set up the ground reference point of total powerstation to the height of instrument eyepiece central point.Total powerstation instrument height
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 height measuring method.Instrument height is vertical range of the measurement control point to centre, is directly surveyed
Amount is not because being flat relation of plane, absolute being error, and steel tape measurement error is larger in addition.
（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 small
In 45 degree.Because if vertical angle is larger, the altitude difference error that trigonometric function is calculated is larger.2. project to ground in outstanding high point
On datum mark erect prism.The line of survey station and ground reference point, the preferably trend with Suspension surveying object intersect vertically.3.
Into the Suspension surveying program of total powerstation, prism height is inputted, alignment prism simultaneously presses measurement key, observation survey station and datum mark prism
Distance.4. unclamping the braking of telescope vertical direction, the outstanding high point above prism is sighted, instrument can turning with vertical circle
It is dynamic, show corresponding ground point to the discrepancy in elevation of outstanding high point.This measuring method operation sequence is cumbersome, and error mainly includes laser
The error that range error, trigonometric function error and the prism introduced are brought.
（3）Laser optical method
The amount of laser light point function having using instrument itself is measured, although laser measurement precision is all higher than above two side
Method, but because hot spot is beaten inside crosshair rather than datum mark peak, systematic error is brought, overall measurement accuracy is limited
System.
The measurement accuracy of above measuring method is grade, inapplicable to need the occasion of fine instrument high parameter.In order to
Meet some elevation high-acruracy survey occasions, it would be desirable to be able to high accuracy, easily measurement total powerstation instrument height apparatus and method.

Embodiment
Embodiment 1, as illustrated in the accompanying drawings from 1 to 3.
The total powerstation of function, including total powerstation, expansion link and displacement meter are measured with instrument high precision, expansion link is vertically pacified
Under the pedestal of total powerstation, expansion link is hollow structure, and displacement meter is arranged on the outside of expansion link.Preferably, expansion link is by two
Section quarter butt concatenation is formed.The reasons why only two sections quarter butts are concatenated is that first, expansion link can be highly transferred to 80mm by two sections of concatenations
Hereinafter, typically use enough, secondly, multistage concatenation is more difficult to ensure the perpendicularity of its junction, can bring bigger measurement error.
Preferably, the cross section of expansion link is equilateral triangle.The reasons why expansion link cross section is equilateral triangle is, in materials and consumption phase
With in the case of, triangle is more circular etc., and polygonized structure is more stable, is not likely to produce Bending Deformation.Preferably, displacement is calculated as mangneto
Telescopic displacement meter, its two ends are separately mounted to expansion link upper and lower ends.
Magneto strictive sensor is the high accuracy displacement sensor developed using " magnetostriction principle ", is connect using non-
Metering system is touched, due to reasons such as friction, abrasions the service life of sensor will not be caused to reduce.Its good environment is adapted to
Property, reliability and stability, it is extremely easy to use, have bright compared with the products such as conductive rubber, LVDT, resistor type displacement sensor
Aobvious advantage.Its output signal is a real absolute position output, rather than ratio or need again enhanced processing
Signal, so in the absence of the situation of signal drift or variate, therefore equally needs not necessarily like other displacement transducers periodically to mark again
And maintenance；Exactly because its output signal is absolute figure, if so power interruptions reclosing also will not be to data receiver structure
It is a problem, more need not returns to zero-bit again.Main reason from magnetostrictive displacement meter is that the optional 50mm of its range is arrived
1000mm or so is chosen in 8000mm, suitable this case of range ability, while its precision may be up to 0.002%, is converted to
1000mm measurement error is 1000 × 0.002mm=0.00125mm, enough for general instrument high measurement accuracy.It is preferred that
Ground, expansion link bottom is substrate, and it is arranged on expansion link lower end.Preferably, substrate is clear glass cylinder shape substrate.It is preferred that
Ground, substrate is detachable.Preferably, alignment laser is vertically mounted under pedestal, in expansion link.Laser-light transparent glass
Glass substrate carries out centering with ground reference point, it is to avoid influence of the presence of expansion link to laser alignment.Preferably, expansion link epimere
The cross section of quarter butt is more than hypomere quarter butt, and having on epimere quarter butt screens screw, expansion link to screw screens screw after shortening will two
Section quarter butt position is fixed.The total powerstation application method：A. total powerstation is set up, now expansion link is in shortening state：B. centering：c.
It is thick flat：D. essence is flat：E. instrument instrument height is measured, expansion link is stretched out, its bottom is touched terrestrial reference, record displacement meter is shown
Reading.
For the centering leveling for the installation influence total powerstation for avoiding expansion link, expansion link 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 expansion link
Light hand operation, must not touch total powerstation.When expansion link 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 expansion link, again centering leveling.In order to further avoid hand from operating
Influence, also it is remote-controlled control unclamp positioner, appoint an expansion link hypomere quarter butt drop to ground reference point by free gravity.
