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.Measurement mark for the high laser measurement of total powerstation instrument, it is characterized in that including measuring mark and white ceramic block, white ceramic block upper surface flat smooth, white ceramic block is embedded and is fixed on measurement mark upper face center, the area of white ceramic block is greater than or equal to the facula area of laser displacement sensor, in use, white ceramic block upper surface center vertical reception and the laser of reflection laser displacement sensor transmitting, laser displacement sensor is 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 white ceramic block, eliminates its error brought to laser ranging；2, white ceramic block upper surface keeps horizontal, ensure that precision of laser ranging；3, white ceramic block upper surface is plane, while material is white ceramic block, can ensure precision of laser ranging.
Description
Technical field
The utility model is related to field of measuring technique, in particular for the measurement mark of the high laser measurement of total powerstation instrument.
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.
For the measurement mark of the high laser measurement of total powerstation instrument, it is characterized in that including measuring mark and white ceramic block, in vain
Ceramic block upper surface flat smooth, white ceramic block is embedded and is fixed on measurement mark upper face center, and the area of white ceramic block is big
In or equal to laser displacement sensor facula area, in use, white ceramic block upper surface center vertical reception and reflection laser
The laser of displacement sensor transmitting, laser displacement sensor are vertically mounted below total powerstation base central.
White ceramic block is cylinder, and surface indentation is below measurement mark upper surface thereon.
The application method of the measurement mark is as follows：
A, mark will be measured to be horizontally fixed on control point；
B, after total powerstation essence is flat, laser displacement sensor is opened, the white ceramic block center measured on mark is aimed at and carries out pair
In；
C, after centering, the instrument height that laser displacement sensor measures is read on total powerstation, which needs plus sharp
Optical displacement sensor to total powerstation scale center height and subtract white ceramic block upper surface be depressed in measurement mark upper surface with
Under difference in height, this two parts height be equipment regular length.
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 white ceramic block, eliminates what it brought to laser ranging
Error；
As long as it is horizontal fixed 2, to measure mark, white ceramic block upper surface keeps horizontal, ensure that precision of laser ranging；
3, white ceramic block upper surface is plane, while material is white ceramic block, is arranged when dispatching from the factory with laser displacement sensor
Index plane material identical, can ensure precision of laser ranging；
4, white ceramic block upper surface is depressed in measurement mark upper surface hereinafter, dialogue ceramic block plays protective effect, prevents
Only it by extraneous scratch and grinds wound.

Fig. 2 is the white ceramic block close-up schematic view of the measurement mark for the high laser measurement of total powerstation instrument；
Fig. 3 is the use state diagram of the measurement mark for the high laser measurement of total powerstation instrument.
In figure：1, mark is measured, 2, white ceramic block, 3, laser displacement sensor, 4 total powerstations.
Specific implementation mode
Embodiment 1
As shown in Figure 1, 2, be used for the high laser measurement of total powerstation instrument measurement mark, it is characterized in that including measure mark and
White ceramic block, white ceramic block upper surface flat smooth, white ceramic block is embedded and is fixed on measurement mark upper face center, white pottery porcelain
The area of block is greater than or equal to the facula area of laser displacement sensor, in use, white ceramic block upper surface center vertical reception
And the laser of reflection laser displacement sensor transmitting, laser displacement sensor are vertically mounted below total powerstation base central.
White ceramic block is cylinder, and surface indentation is below measurement mark upper surface thereon.
As shown in figure 3, the application method of the measurement mark is as follows：
A, mark will be measured to be horizontally fixed on control point；
B, after total powerstation essence is flat, laser displacement sensor is opened, the white ceramic block center measured on mark is aimed at and carries out pair
In；
C, after centering, the instrument height that laser displacement sensor measures is read on total powerstation, which needs plus sharp
Optical displacement sensor to total powerstation scale center height and subtract white ceramic block upper surface be depressed in measurement mark upper surface with
Under difference in height, this two parts height be equipment regular length.
