Description of reference numerals: 1-profile measurer, 2-inertial navigator, 3-illuminating lamp, 4-camera, 5-hoisting device magnet, 6-support lower floor, 7-support upper strata.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, high-speed railway rail measurement mechanism of the present invention, comprise support lower floor 6, support upper strata 7, support upper strata 7 fixedly mounts hoisting device magnet 5, and device of the present invention adopts hoisting device magnet adsorption on train head.When the present invention uses, can directly hang aboard, need not reequip train head, finish using also for convenience detach.High-speed railway rail measurement mechanism is hung ON TRAINS, makes support lower floor 6 be 105 millimeters apart from race orthogonal height.
As shown in Figure 1, illuminating lamp 3, profile measurer 1, inertial navigator 2, camera 4 are installed from front to back successively by support lower floor 6 of the present invention.The present invention needs to guarantee, when using illuminating lamp 3 night, its irradiation light in orbit, just in time in camera 4 image pickup scope, guarantees system normal acquisition image.Specifically, two illuminating lamps 3 of the present invention are LED illumination lamp, and its symmetry is arranged on the front side of support lower floor 6, and it is 25 degree that illuminating lamp 3 tilts backwards angle.6 uniform tops being arranged on illuminating lamp 3 of camera 4, exceed 580 millimeters according to bright lamp 3, and its angle that turns forward is 10 degree, and the distance between 2 cameras 4 is 400 millimeters, can guarantee that the width of 6 cameras 4 is 2.4 meters like this.The requirement that camera 4 of the present invention is selected is the line scan camera that Transistor-Transistor Logic level triggers, and line frequency is greater than 67K, Camlink high-speed transfer, can guarantee can clear to take pictures out the crack of 0.3 millimeter in 80 kilometers of running velocity situations.
As shown in Figure 1, inertial navigator 2 of the present invention is MU inertial navigator 2, and inertial navigator is arranged on high-speed railway rail measurement mechanism in middle, can improve the survey precision that train tilts like this, facilitate native system to the compensation of inclination conditions.
As shown in Figure 1, two profile measurers 1 of the present invention are symmetricly set on high-speed railway rail measurement mechanism, its distance is each other 1050 millimeters, profile measurer 1 to be arranged on rear side of illuminating lamp 3 250 millimeters, 170 millimeters are exceeded according to bright lamp 3, the profile measurer 1 on the left side angle that is tilted to the left is 25 degree, and the profile measurer 1 on the right angle that is tilted to the right is 25 degree.By as above arranging, can guarantee that two profile measurers 1 just in time measure the profile of left and right two rails respectively, and forming good coordinating with illuminating lamp 3.
High-speed railway rail measurement mechanism of the present invention also comprises data acquisition processing system, data acquisition processing system is for gathering the data of the devices such as storage wheel profile measuring apparatus 1, inertial navigator 2 and camera 4,2 chaptrel profile measuring apparatus 1 of the present invention are with the profile of frequency scanning two tracks of 1k, 6 CCD camera 6 are with the image of the frequency scanning track plates of 80K, acquisition processing system utilizes network communication by the data unification of each sensor on a time shaft, the original data of each sensor, at 0.5 millisecond, then preserves by precision controlling.
The invention also discloses the method for measurement of high-speed railway rail, this method of measurement processes in such a way to the data that acquisition processing system stores.
The original data of steps A, analysis profile measurer, calculate track space, and two, left and right track profile and standard model are contrasted obtain rail head and wear and tear, distance values and abrasion loss are exported (now exporting time coordinate when data coordinates is from gathering);
Step B, to analysis of image data, in the data of time sampling, the technology of fuzzy diagnosis is utilized to be identified by the rail clip in image;
Step C, utilize the stationarity of fastener spacing and the time coordinate of each fastener, set up the time coordinate of original data and the mapping relations of range coordinate.Because in train driving process, often need to pass through cavern, valley, these positions can not adopt Big Dipper location, GPS position fixing system, and the data of collection of the present invention need location, so just facilitate and keep in repair problematic track.Fastener spacing in this step is the length of rail, fixes, after identifying rail clip quantity, be multiplied by by rail clip quantity the distance that rail length can determine measurement point and initial point because often save rail length.Again because for concrete road, its travel direction and path are fixed, so will can specifically have the tracks positioned of wear problem by the method.
Step D, when utilizing apart from virtual borderlines relation by track plates image by distance resampling, obtain the track plates image of distance samples;
Step e, apart from virtual borderlines relation, the distance values exported in steps A and abrasion loss are scaled range coordinate when utilizing.
The invention has the beneficial effects as follows: native system is the equipment of a hanging-connecting, time in its on-hook to locomotive, do not relate to and have any destructive erection work to train; In order to solve orientation problem, native system adopts afterwards according to the technology of the information resampling of fastener image, makes the structure of system become simpler like this.
