Description
Technical field
This utility model relates to desk-top smooth shaft detection device, particularly to total powerstation light shaft detection device.
Background technology
The range finding ultimate principle of total powerstation is: the laser after being modulated by laser tube emissions signal, laser impinges upon quilt after target
Reflection returns, and the reception system of total powerstation is launched between signal and return signal by computed in software after receiving return signal
Phase contrast, thus obtain the distance between total powerstation and target.Generally, for reducing light damage in two-way process
Losing, and also to reduce the volume of total powerstation, strengthen the compactedness of its structure, total powerstation all uses the structure of close coupled type
Design, i.e. the emergent light axis (emission shaft) of laser, the reception optical axis (reception axle) of return signal, collimation telescope mesh
Target optical axis (sighting axle) shares same object lens, and the three of the total powerstation namely often said are coaxial.But the reality at instrument
In assembling, it is impossible to reach theoretic complete three coaxial, and instrument is during transport and using, due to vibrations,
The impact of the environment such as variations in temperature, can make the three of instrument coaxially change, so the production at instrument is assembled and maintenance
Calibration is required for coaxially detect the three of total powerstation, makes up in the range of standard-required.
Three coaxial in the most commonly used detection method of emission shaft be one cross target of placement a long way off, instrument is used
Pedestal is locked at calibration platform.With the cross target's center of collimation telescope distant object (telescopical graticle crosshair with
Target cross overlaps, and instrument is in the state of sighting), then lock the transverse axis of instrument, vertical pivot, open laser, and record
The now angular readings (horizontal angle, vertical angle) of instrument.Then adjusting the fine motion handwheel of instrument, adjustment limit, limit is observed and is swashed
Light hot spot, until laser spot center overlaps with the cross searching of distant object, then records the angle value of now instrument,
The difference of twice angle value is instrument emission shaft and the deviation value sighting axle.Adopt at present to exist in this way and take up room greatly
(need a long way off drop target), to observe inconvenient (observing facula position at a distance easily not see), manual operation subjective
Property strong, the most disturbed and interrupt shortcomings such as (just cannot be carried out detection when having people or thing to block hot spot) when detection.
Utility model content
This utility model solves the technical problem that being to provide a kind of automatic decision total powerstation launches the position of optical axis and provide calculating
The total powerstation light shaft detection device of result.
This utility model solves its technical problem the technical scheme is that total powerstation light shaft detection device, including base, entirely
Instrument of standing locking pedestal and CCD camera, described CCD camera is connected with processing system, described total powerstation locking pedestal and CCD
Photographic head is connected by connector and base are fixing respectively.
Further: also include the telescope being provided with graticle, described telescope is connected by connector and base are fixing,
And telescope is arranged between total powerstation locking pedestal and CCD camera, CCD camera imaging center and telescopical graduation
Plate center superposition, telescopical eyepiece is towards CCD camera.
The beneficial effects of the utility model are: this utility model is served as infinity by the telescopical graticle crosshair of optical system
The target at place, is carried out the deviation value calculating emission shaft and sighting between axle, has by camera imaging supporting inspection software
Taking up room little, when sighting, run-home is clear, detects simple to operate, reduces manual operation impact, improves calculating
The speed of result and degree of accuracy.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of total powerstation light shaft detection device.
Figure is labeled as: base 1, telescope 2, CCD camera 3, total powerstation locking pedestal 4, total powerstation to be measured 5.
Detailed description of the invention
With detailed description of the invention, this utility model is further illustrated below in conjunction with the accompanying drawings.
Total powerstation light shaft detection device as shown in Figure 1, including base 1, total powerstation locking pedestal 4 and CCD camera 3 (CCD
Being the english abbreviation of Charge-coupled Device, Chinese full name is charge coupled cell, is properly termed as ccd image sensor,
Also being image controller, CCD is a kind of semiconductor device, it is possible to optical image is converted into digital signal), described CCD takes the photograph
Picture 3 is connected with processing system, and described total powerstation locking pedestal 4 and CCD camera 3 are respectively by connector and base 1
Fixing connection, described connector can be bolt, and screw etc. is used herein as bolts and nuts and fixes.When needs detect, will
Total powerstation to be measured is placed on total powerstation locking pedestal, locks total powerstation 5 to be measured with pedestal, then aims at CCD with total powerstation to be measured
The imaging center of photographic head 3, now, opens the laser of total powerstation 5 to be measured, and laser projects CCD camera by distance
On 3, laser imaging in upper computer detection software, is judged total powerstation 5 optical axis to be measured by software by CCD camera 3
Position also provides result of calculation, and this kind of method can calculate emission shaft and the deviation value sighting between axle automatically, simple to operate,
Reduce manual operation impact, improve speed and the degree of accuracy of result of calculation.
In addition, this covering device also includes the telescope 2 being provided with graticle, and described telescope 2 is by connector and base
Fix and connect, and telescope 2 is arranged between total powerstation locking pedestal 4 and CCD camera 3, CCD camera 3 imaging
Center and the graticle center superposition of telescope 2, telescopical eyepiece is towards CCD camera, during use, by instrument to be detected
The graticle crosshair of the telescope 2 that the graticle crosshair on the telescope of 5 is fixing with on total powerstation light shaft detection device reaches
The most clear state and both coincidences, the telescope graticle center on total powerstation the most to be measured, the prestige of total powerstation light shaft detection device
The imaging center of remote mirror graticle center and CCD camera 3 is coaxial.Now the looking in the distance of total powerstation light shaft detection device
The graticle crosshair of mirror 2 serves as the target of infinite point, shortens the distance between total powerstation 5 to be measured and CCD camera 3,
Reduce taking up room of package unit so that run-home when sighting is apparent.
Particular embodiments described above, has been carried out the purpose of this utility model, technical scheme and beneficial effect the most in detail
Illustrate, be it should be understood that and the foregoing is only specific embodiment of the utility model, be not limited to this practicality new
Type, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, should be included in
Within protection domain of the present utility model.
