Abstract

The invention relates to an optical geodesic measurement device. The optical geodesic measurement device can provide a horizontal true angle. The optical geodesic measurement device comprises an optical module and an orientation module. The orientation module comprises a host computer module and a calibration module. The orientation module is utilized for horizontal true calibration and provides a true angle for the optical module. The optical module has a physical connection with the host computer module. The optical module has functions same as functions of a well-known total station. The orientation module adopts a real-time differential GPS system and comprises the host computer module and the calibration module. The host computer module is utilized as a real-time differential GPS movement station and is installed on the optical module. The orientation module is utilized as a real-time differential GPS base station. After difference, a horizontal true angle is written in an internal memory. When an optical lens aims at a marker of the orientation module, a direction arrangement button is triggered, and the optical geodesic measurement device can obtain a horizontal true angle of the orientation module relative to the host computer module and utilize the horizontal true angle as a horizontal direction reference angle.

A kind of optics geodetic surveying equipment

Affiliated technical field

The present invention relates to a kind of optics geodetic surveying equipment, particularly a kind of level that can provide is very to the optics geodetic surveying equipment of angle.

Background technology

At present, known optics geodetic surveying equipment comprises transit and total powerstation, and wherein total powerstation is on the transit basis, to load distance-measuring equipment, and its angle measuring principle is identical with transit.No matter being transit or total powerstation, all is to obtain vertically very to angle through weight, but can not provide level very to angle (level angle in relative geographical north in terrestrial coordinate system).When carrying out geodetic surveying, if the level that obtains target is very to angle, need be by compass or differential GPS.When using compass, need know local magnetic declination, ability acquisition level is very to angle, and this method precision is low, complicated operation; Use differential GPS to need to measure earlier two points; Through the distance of real-time or aftertreatment difference acquisition point-to-point transmission baseline with very to angle (comprising level) very to angle; Use existing optics geodetic surveying equipment (like total powerstation or transit+stadimeter) to measure this two points then; The level that calculates is very to angle, and this method precision is very high, but operation is complicated more.

Summary of the invention

Can not provide level very to the deficiency of angle in order to overcome existing optics geodetic surveying equipment; The present invention provides a kind of optics geodetic surveying equipment; This equipment not only has the repertoire of total powerstation; And the level that the target of surveying can be provided is simple to operate very to angle, and angle precision is consistent with the precision that the differential GPS method records.

The technical solution adopted for the present invention to solve the technical problems is:

This measuring equipment is made up of optical module and orientation module two parts, and orientation module is made up of host module and calibration module, and orientation module is used for level very to demarcation, for optical module provides very to angle, and described optical module and host module physical connection.Optical module in order to provide target range, target Relative Zero to level angle and relative gravity direction vertical angle.Described orientation module adopts the real time differential GPS system, and this module is divided into calibration module and two parts of host module.During use, calibration module is as the base station of real time differential GPS, and host module is as movement station.

Described calibration module comprises: calibration gps antenna and calibration GPS receiver are used to receive gps signal; Transmitting station is used to launch differential signal; The boresight antenna shell, boresight antenna outer casing top surface center is provided with mark, is used for the optical device aiming.

Described host module comprises: main frame gps antenna and main frame GPS receiver are used to receive gps signal; Receive the radio station, be used to receive the differential signal of calibration module emission; The FPGA difference is resolved plate, is used for the real-time resolving differential data; With the master machine antenna shell.

Described FPGA difference resolve plate with the distance of line between calibration module and host module with very to angle is delivered to the internal memory of optical module through serial interface cable in, store.

The surface of described optical module is provided with puts to key, puts to key to be used for level that opertaing device reads the optical module internal memory very to angle information, as the present level angle.

The antenna casing of described host module and calibration module is a disc.

The invention has the beneficial effects as follows that on the basis of known total powerstation, the level that can directly obtain the target of surveying is very to angle, exempted and used existing optics geodetic surveying equipment acquisition level very to the complicated process of angle.

Embodiment

Like accompanying drawing 1, Fig. 2 and shown in Figure 3, main frame gps antenna shell 1 is installed on the handle 2 through web member 3, not the time spent desirable down, optical lens 4 is consistent with general total powerstation with display screen 5, puts " zero setting " button that is similar to general total powerstation to key 6; Mark is a cone-shaped body, is installed in calibration gps antenna shell 8 end faces center, and emitting antenna is positioned at calibration gps antenna shell 8 below non-central locations, and support bar 10 is installed in center, calibration gps antenna shell 8 bottom surfaces, and the time spent can not screw off.

Calibration gps antenna 17 receives gps satellite signal, after treatment the differential GPS signal is transmitted in the air through transmitting station 16 and emitting antenna 9; Main frame gps antenna 11 receives gps satellite signal; Receive the differential GPS signal that radio station 13 receives from transmitting station 16, resolve plate 12 through the FPGA difference and calculate, obtain baseline information; Be that main frame gps antenna 11 phase centers are to the distance of calibration gps antenna 17 phase centers with very to angle; Comprise level very to angle, and level is very passed through serial port data line 14 write memories 15 to angle, when putting when key 6 is triggered; Main frame reads level on the internal memory 15 very to angle, is changed to the level angle of current optical lens 4.

The use operation steps of optics geodetic surveying equipment:

At first should make host module and calibration module can both receive gps signal; Calibration module is placed optical lens 4 observable distant places as far as possible; Use the crosshair sighting mark thing 7 in the optical lens 4, to key 6, liquid crystal display 5 can show the present level angle by underlying; Just accomplished the initialization of equipment this moment, just can begin geodetic surveying work afterwards.

Calibration module and host module farther apart are very high more to precision.Generally speaking, two module distance R rice are 0.2 °/R to precision very.For example two modules are 0.002 ° to precision very then at a distance of 100 meters.
