Background technology
Static GPS survey is one kind that positioning measurement is carried out using measurement type GPS.It is mainly used in establishing various
Control net.During GPS static measurements, the position of the antenna of GPS in whole observation process is static, in data processing
When, using the position of receiver antenna as an amount not changed with the change of time, pass through the satellite data that receives
Change to try to achieve the coordinate of point to be located.
RTK（Real - time kinematic）Real time dynamic differential method.This is a kind of new conventional GPS measurement sides
Method, former static state, rapid static, dynamic measurement are required for carrying out resolving the precision that could obtain Centimeter Level afterwards, and RTK is
The measuring method of centimeter-level positioning precision can be obtained in real time in the wild, it employs carrier phase dynamic real-time difference method.
At present, RTK measuring instruments centering leveling makes bubble in levelling tube placed in the middle, it, which is flattened, is present by adjusting A-frame
Error, accuracy are low.It is to measure oblique distance by vertical height to measure GPS height, and this method of principal components is not very accurate.Instrument
After optical centering flattens, the height of position is portrayed to RTK measuring instrument vertical planes with steel tape or tape measure datum mark, is measured
Data are needed to be manually entered, and measurement result is influenceed greatly by ground flat degree, human factor etc., and actual measurement data has error.
Utility model content
The purpose of this utility model is main in providing based on static GPS survey in RTK pairs and device that measuring instrument is high
Solve measuring instrument leveling in the prior art exist error, measurement height by ground flat degree and human factor influenceed it is big, survey
The problems such as error, need to be manually entered in measuring instrument be present in amount data.
To achieve these goals, the technical solution adopted in the utility model is as follows：
Based on the high device of RTK centerings in static GPS survey and measuring instrument, including RTK measuring instruments, for supporting and consolidating
The A-frame of RTK measuring instruments is determined, installed in RTK measuring instruments bottom centre position, for infrared centering and measuring instrument height
Laser centring device, and in RTK measuring instruments, for control laser centring device output ranging carrier signal carrier wave
Device.
Specifically, RTK measuring instruments bottom centre position is provided with the fixing hole of installation laser centring device, and fixing hole bottom is set
Matched level crossing.
Preferably, laser centring device includes being arranged on level crossing top, for launching and the Laser emission of reception signal connects
Receive device, be connected on Laser emission receiver, for carrier signal extraction filter, and connection on the filter, be used for
The converter of carrier signal opto-electronic conversion.
Further, A-frame crown center position sets the through hole that aperture is more than fixing hole, passed through for laser beam,
Laser emission receiver is arranged on fixing hole and the same central axis of through hole.
Compared with prior art, the utility model has the advantages that：
The utility model is by adjusting A-frame height, laser centring device centering leveling, Carrier control Laser emission
Device launches ranging carrier signal, receives the ranging carrier wave of reflection, extracts carrier signal in the filter, and enter in converter
Row opto-electronic conversion, because of carrier signal, constant airspeed, measure electromagnetic wave come in the tested time apart from upper roundtrip propagation in atmosphere
Try to achieve distance value.The device can quickly and accurately realize that, to neutralizing measuring instrument height, the device has quick for installation, use
It is convenient, precision is higher, the advantages that calibrating automatically, have higher application value in engineering construction fields of measurement.
