Theodolite it is accurate whether directly influence the accuracy of its measurement result, therefore, had to pass through before use tight
The measurement verification of lattice, and theodolite will produce certain error in use for some time, it often will be at detection scene to warp
Latitude instrument is calibrated, it requires theodolite calibrating installation can it is simple it is portable, weight is lighter.
At present, there are mainly two types of the methods for examining and determine theodolite.Multiple target method:Using several parallel light tubes as infinity mesh
Mark is measured the one measuring process standard deviation of theodolite and is erected using the method for wholecircle method of direction observation and station adjustment
The verification parameters such as right angle standard deviation；Multiteeth indexing table method:Use a parallel light tube as infinity target, it is vertical with one respectively
Formula and horizontal multiteeth indexing table as horizontal angle and vertical angle standard calibrating theodolite one measuring process standard deviation and
One survey time vertical angle standard deviation.Quoted from periodical《Measurement technology》The 3rd 29-31 pages of phase " theodolite calibrating dress of volume 30 in 2010
Set vehicle-mountedization design ".
All do not have collimation micrometer function without eyepiece micrometer device in current measurement method and calibrating installation, it cannot
Angle of inclination and the angle change of speculum are detected, and build is heavier, the requirement calibrated at detection scene cannot be met,
Therefore a kind of portable, with collimation micrometer function novel theodolite calibrating installation is needed.

Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment invention is further described in detail.
A kind of theodolite calibrating installation, including light source 1, eyepiece micrometer device 2, Amici prism 3,3m graticles 4, small reflection
Mirror 5, large reflective mirror 6, object lens 8, each component are each attached on shell 14,1 upper end of light source have collimation graticle 13, light source 1 it is upper
Side is eyepiece micrometer device 2, Amici prism 3 is installed on eyepiece micrometer device 2, before 3m graticles 4 are mounted on Amici prism 3
End is small reflector 5 and large reflective mirror 6 in the right of light source 1, eyepiece micrometer device 2, and small reflector 5 is parallel with large reflective mirror 6
It places, object lens 8 is installed in the right flank middle part of shell 14, and it is parallel to install with lower part height respectively on the top of 14 right side of shell
Light pipe 7, low parallel light tube 9；The light that level passes through object lens 8 is collimated light, high parallel light tube 7 and collimated light, low parallel light tube 9
Angle between collimated light is fixed as 18 °；
Eyepiece micrometer device 2 includes reading reticle 10, instruction graticle 11 and microdrum 12
When work, theodolite calibrating installation is fixed on leveling tripod first, calibrating installation is tuned into water with bubble
Flat, precision is 10 ".When pair warp and weft instrument is calibrated, theodolite is placed in the front of theodolite calibrating installation.Speculum is measured to incline
When angle, is placed on the collimated ray road in 8 front of object lens and be tested speculum or right-angle prism, open light source 1, by collimating graduation
The light of plate 13 is mapped to after Amici prism 3 on small reflective mirror 5, is reflected on big reflective mirror 6, is re-reflected into through small reflective mirror 5
It is emitted on object lens 8, the light of outgoing passes through object lens 8, big reflective mirror 6, small reflective mirror 5, light splitting rib after tested speculum reflection
Mirror 3 enters eyepiece micrometer device, and the reflected image from eyepiece micrometer device is calculated according to the offset of image
The angle of inclination of tested speculum.
Angle measuring principle is as shown in Figure 3.The graticle of collimator is placed in away from the light that at objective focal length f, light source is sent out from center o
Point, by speculum to deflect 2A corner reflections, is imaged on the o' points of graticle, displacement x=oo' through objective lens exit.By geometry light
A=arctan (x/2f) known to learning principle, measures displacement x and can find out on measured target and reflect in the case of known focal length f
The deflection angle A of mirror in the direction indicated.
As shown in figure 4, when measuring, speculum is rotated, so that the vertical line of reflected collimation graticle image 13 is located at and reads
The registration 10 or so of number graticle, rotates the microdrum 12 in Fig. 2, makes the vertical line and instruction graticle of collimation graticle image
11 black silk overlaps, and writes down the reading of groove in eyepiece at this time, reads read-only integer-bit in eyepiece, a lattice represent microdrum
One lattice of 100 lattice, microdrum represent 1.03 ", reading can be estimated to 0.5 lattice, the reading of microdrum is added, write down the reading of the two
The sum of number a1, the as angle that tilts of speculum at this time rotates speculum, will collimate graticle according to the method described above again
The black silk of vertical hair and instruction graticle overlaps, and writes down in eyepiece and the sum of drum reading a2, twice read difference a2-a1It is as anti-
Penetrate the angle of mirror rotation.
Micrometer device is read in collimator in measurement range ± 100 " in, angle measurement accuracy is 3 ".
