Description
Technical field:
The present invention relates to the orbit measurement instrument, particularly relate to 300 meters long-chord railway track measurement self-calibrating devices of laser.
Background technology:
At present, raising along with the railway locomotive travelling speed, reached 200 kms-350 km/hour, the precision measurement of the uneven compliance of track long wave has been become the important content of track detection, adopt laser long-chord 300M to implement laterally, deviation is measured longitudinally to track, the variation of can run into extraneous temperature, wet, pressing brings the air-flow shake to cause change of refractive, cause the basic string of laser when remote, can produce the variation of position, the error that causes measurement result causes the measurement of track long wave irregularity to become a great problem.
Summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, provide a kind of laser 300 meters long-chord railway track measurement self-calibrating devices, simple in structure, Intelligent Measurement, intensity is low, and is easy to operate, the precision height.
The technical scheme that the present invention is adopted for achieving the above object is: 300 meters long-chord railway track measurement self-calibrating devices of laser, form by light source 1, traverse measurement target 2 and calibration receiving target 3, wherein light source adopts the laser transit (patent No.: 200720306434.x) that has the space bit phase modulation, calibration receiving target, traverse measurement target adopt the ring grid digital received target (patent No.: ZL200510047340.0), it is characterized in that: light inlet 5 and light-emitting window 6 are arranged on the traverse measurement target, be provided with spectroscope 4 between light inlet 5 and the light-emitting window 6;
300 meters long-chord railway track measurement self-calibrating devices of described laser, spectroscope is a half-reflecting half mirror;
300 meters long-chord railway track measurement self-calibrating devices of described laser are connected with target car 7 on the traverse measurement target;
300 meters long-chord railway track measurement self-calibrating devices of described laser, the structure of light source 1 and calibration receiving target 3 adopts patent name to be: (patent No.: the 200920249436.6) structure of narrating in this patent just repeats no more high speed railway track long wave irregularity precision measuring instrument here.
The present invention compares with classic method has outstanding feature:
1. set up the laser optical system that the 300m long-chord is not focused;
2. calibration receiving target, traverse measurement target have been realized digitized sampling;
3. for making calibration receiving target, traverse measurement target collect the optical signalling of reference chord simultaneously, guaranteed that the change in location of basic string when sampling in time revised, adopted special beam-splitting optical system.
The present invention also has design science, application height, simple operation and other advantages.
Description of drawings:
Fig. 1 is a system architecture synoptic diagram of the present invention.
Embodiment:
The present invention is described in further detail below in conjunction with embodiment and accompanying drawing: as shown in Figure 1.300 meters long-chord railway track measurement self-calibrating devices of laser are made up of light source 1, traverse measurement target 2 and calibration receiving target 3, and wherein light source adopts the laser transit that has the space bit phase modulation.Calibration receiving target, traverse measurement target adopt ring grid digital received target.Be provided with half-reflecting half mirror 4 between the light inlet 5 of traverse measurement target and the light-emitting window 6.The structure of light source 1 and calibration receiving target 3 adopts patent name to be: the high speed railway track long wave irregularity precision measuring instrument (patent No.: the 200920249436.6) structure of narrating in this patent.Be connected with target car 7 on the traverse measurement target.In use, at first get the datum line that laser ring grid light beam that a directional transmissions need not to focus is measured to, height as rail, detect and become possibility for finishing the smooth-going degree of track long wave by light source.This Shu Guang is refracted on the ring grid digital receiver of traverse measurement target through half-reflecting half mirror by the light inlet 5, a tunnel of traverse measurement target.Another Reuter crosses half-reflecting half mirror and projects on the ring grid digital receiver of calibration receiving target through light-emitting window 6.Just can revise the sampling numerical value of traverse measurement target by time control sampling, thereby finish purpose of design of the present invention according to the data that far-end is calibrated receiving target.Initiative of the present invention overcome the present shortcoming that faces, have science reasonable in design, advantage such as simple in structure, easy to operate.
