Abstract
Problem to be solved in the utility model is measured so that measuring mark and being suitable for the high high-precision laser of instrument.The measurement mark for the high laser measurement of total powerstation instrument embedded with total reflection prism, it is characterized in that including measuring mark and total reflection prism, total reflection prism upper surface flat smooth, total reflection prism is embedded and is fixed on measurement mark upper face center, the area of total reflection prism is greater than or equal to the facula area of laser displacement sensor, when use, total reflection prism upper surface center vertical reception and the laser of reflection laser displacement sensor transmitting, laser displacement sensor are vertically mounted on total powerstation base central lower section.The measurement mark has the beneficial effect that：1, the groove measured at the upper centering mark of mark is replaced using total reflection prism, eliminates its error brought to laser ranging；2, total reflection prism upper surface keeps horizontal, ensure that precision of laser ranging；3, horizontal total reflection prism can greatly ensure precision of laser ranging.
Description
Technical field
The utility model is related to field of measuring technique, and be especially embedded with total reflection prism is used for the high laser of total powerstation instrument
The measurement mark of measurement.
Background technology
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 laser measurement method is grade, cannot meet certain high-acruracy survey occasions.Existing survey
Amount mark is not suitable for the high high-precision laser of instrument and measures, and the high laser measurement of instrument is caused to be difficult to practical and promote.
Invention content
Problem to be solved in the utility model is measured so that measuring mark and being suitable for the high high-precision laser of instrument.
The measurement mark for the high laser measurement of total powerstation instrument embedded with total reflection prism, it is characterized in that including measuring mark
Will and total reflection prism, total reflection prism upper surface flat smooth, total reflection prism is embedded and is fixed on measurement mark upper surface
Center, the area of total reflection prism is greater than or equal to the facula area of laser displacement sensor, in use, total reflection prism upper table
The laser that face center vertical reception and reflection laser displacement sensor emit, laser displacement sensor are vertically mounted on total powerstation base
Seat central lower.
Total reflection prism upper surface is square, and surface indentation is below measurement mark upper surface thereon.
The measurement mark 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
Device has the beneficial effect that：
1, the groove measured at the upper centering mark of mark is replaced using total reflection prism, is eliminated it and is brought to laser ranging
Error；
As long as it is horizontal fixed 2, to measure mark, total reflection prism upper surface keeps horizontal, ensure that precision of laser ranging；
3, horizontal total reflection prism can greatly ensure precision of laser ranging；
4, total reflection prism upper surface is depressed in measurement mark upper surface hereinafter, dialogue ceramics play protective effect, prevents
Only it by extraneous scratch and grinds wound.
