Description
Technical field
The utility model is related to field of measuring technique, the especially high measurements of total powerstation instrument.
Background technology
Instrument higher position is to set up the ground survey control point of total powerstation to the vertical distance of instrument scale central point.Total powerstation
The high precision of instrument directly determines the precision of coordinate elevation to be measured and trigonometric levelling, the influence for entire measurement accuracy
It is very big.
（1）Steel tape mensuration
Most traditional instrument high measurement method.Instrument height is vertical distance of the measurement control point to instrument scale center, directly
Measurement is connect because not being flat relation of plane, there are errors, and in addition steel tape measurement accuracy is not high.
（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 calculates is larger.2. projecting 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 turn with vertical circle
It is dynamic, show corresponding ground point to the height difference for hanging high point.This measurement method operation sequence is cumbersome, and error includes mainly laser
The error that the prism of range error, trigonometric function error and introduction is brought.
（3）Laser optical method
Currently, there is a kind of laser ranging total powerstation instrument height measuring system, laser displacement sensor is vertically mounted to entirely
It stands under instrument pedestal, it is high can easily and efficiently to read total powerstation instrument for the measurement mark being aligned on ground.It is existing important
Problem is to have ignored to measure the millimetre-sized error that the groove at the upper centering mark of mark is brought to laser ranging.This is because,
1, when laser alignment, laser center is injected into groove, and the distance of measurement may be deep into inside grooves, is not to measurement
Indicate the distance of top end surface；2, inside grooves and its surrounding are rough, cause laser reflection light direction chaotic, are swashed
The intensity of reflected light and poor quality that optical receiving end receives bring very big error to laser ranging.
The measurement accuracy of the above measurement method is grade, the not applicable occasion for needing fine instrument high parameter.In order to
Meet certain elevation high-acruracy survey occasions, needs high-precision, easy-to-use total powerstation instrument height measuring system and method.
Invention content
Problem to be solved in the utility model is to improve the high laser measurement precision of total powerstation instrument.
A kind of laser ranging total powerstation instrument height measuring system, including total powerstation and laser displacement sensor, laser displacement

The system is applicable not only to total powerstation, it can also be used to which the needs such as spirit level, GPS, prism measure the instrument of height, have
Beneficial effect is as follows：
1, the groove measured at the upper centering mark of mark is covered using laser reflection cap, is eliminated it and is brought to laser ranging
Error；
2, the accurate leveling of laser reflection cap energy, laser reflection cap are covered on measurement mark spherical surface hill, utilize spirit level
By laser reflection cap leveling, while it is plane, the index plane phase being arranged when dispatching from the factory with laser displacement sensor to reflect cap upper surface
Together, it ensure that precision of laser ranging；
3, laser reflection cap upper surface is white pottery porcelain, the index plane material phase being arranged when dispatching from the factory with laser displacement sensor
Together, it can ensure precision of laser ranging；
4, laser reflection cap bulk material is permanent magnet, laser reflection attractive to the measurement mark of steel
When cap deflection, equally it is in close contact with measurement mark upper surface, avoids operating error.
