Description
Technical field
The utility model relates to railway switch field, specifically refers to a kind of switch machine indication notch detecting device.
Background technology
Current switch machine indication notch detects and realizes mainly through 3 kinds of methods:
1, mechanical switch mode
By checking that post or indication rod tail end are transformed to switch machine, built-in collision bead type mechanical switch, after switch machine indication notch is displaced to thresholding, mechanical switch touches indication notch edge, thus carries out alarm to indication notch skew.Which only can realize alarm, cannot provide switch machine indication notch numerical value and variation tendency, cannot meet consumers' demand.
2, photo-electric detection mode
By at switch machine indication bar tail end installation infrared grating or edd current transducer, detect switch machine indication bar displacement, indirectly obtain indication notch numerical value.Which is indirect measure, only can monitor the displacement of switch machine indication bar, but two elements (indication rod breach edge, inspection post edge) any one change forming indication notch all can cause indication notch numerical value change, and the numerical value measured in like fashion can exist error with the actual indication notch numerical value in scene.Be subject to the impact such as greasy dirt at the scene and cause flase alarm, and switch machine must be opened just can carry out examining whether flase alarm in scene after flase alarm, affect Analysis of Train Operation Order.
3, image recognition detection mode
By installing image collecting device in switch machine, shooting indication notch region, obtains indication notch edge by image recognition technology, calculates indication notch side-play amount by indication notch edge change in location in the picture, and then obtains indication notch numerical value.Which is non-contact detecting mode, and can directly obtain indication notch numerical value, safety is good.At the scene because of the environmental factors such as greasy dirt cause report to the police time, directly can carry out manual confirmation by image in indoor, avoid scene to open switch machine and examine, do not affect Analysis of Train Operation Order.
Above-mentioned 3 kinds of modes preferably resolve S700K by conventional images recognition detection mode, the detection of ZD6 switch machine type indication notch, but for ZYJ7, SH6, ZDJ9, ZYJ4, SH5, the indication notch of ZYJ6 type detects and has the following disadvantages: due to installation site restriction, the indication notch region that image collecting device photographs is stravismus angle, indication rod breach edge can only be detected, can not directly obtain checking post edge, therefore the displacement of switch machine indication bar can only be monitored, but form two elements (indication rod breach edge of indication notch, checking post edge) any one change all can cause indication notch numerical value change, error can be there is in the numerical value measured in like fashion with the actual indication notch numerical value in scene.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail:
Shown in accompanying drawing 1 to Fig. 5, switch machine indication notch detecting device of the present utility model, comprise the image collection assembly that relative switch machine is fixing, image collection assembly is towards the indication notch checked between post 1 edge and indication rod 2 edge, also comprise the Laser emission assembly that relative switch machine is fixing, the laser mark line that Laser emission assembly is launched is positioned at and checks post 1 and indication rod 2 Plane intersects position.
Switch machine has base 3, checks post 1 and the displacement of indication rod 2 respect thereto 3.The image collection assembly of the present embodiment comprises camera 4, and Laser emission assembly comprises laser transimitter 5, and camera 4 and laser transimitter 5 are all fixedly installed on support, and support respect thereto 3 is fixedly connected with.
Camera 4 is pressed close to check post 1 and is relatively checked that post 1 is obliquely installed, and camera 4 pickup area covers and checks post 1 and indication rod 2 displacement limits position separately.Also comprise the light fixture for improving indication notch regional luminance.Light fixture comprises illuminating lamp 6, and illuminating lamp 6 is fixedly mounted on the fixing support of relative positioning base.The illuminating lamp of the present embodiment is LED.
Switch machine is movably set with a pair inspection post 1 and a pair indication rod 2, and each checks that post forms indication notch with corresponding indication rod, and two groups of indication notch arrange image collection assembly and Laser emission assembly respectively.
The utility model is realized indication rod breach edge simultaneously by image recognition detection technique, is checked the position probing at post edge, thus also improves method of inspection.
By arranging laser transimitter on indication notch detecting device, laser mark line is transmitted into the position checked with indication rod Plane intersects on post, due to directional lighting characteristic, the following feature of laser on projection thing of laser, when after the displacement of inspection post, projection laser mark line thereon also can follow movement, the miles of relative movement of laser mark line detected, the miles of relative movement checking post also just detected.In the indication notch area image photographed by image collecting device, observable also recognizes indication rod breach edge, the laser mark line position checked on post, can accurately identify switch machine indication notch actual size.
The method efficiently solves in traditional indication notch image recognition technology due to installation site stravismus, it is seen that inspection cylinder, None-identified checks the problem of the variable quantity of post, solves when checking the problem that cannot detect indication notch actual value after post position changes.
Indication notch detecting device comprises: image collection assembly, laser mark line emitting module, light fixture.Described image collection assembly comprises camera, and laser mark line emitting module comprises laser transimitter, and light fixture comprises illuminating lamp.This device mainly detects the indication notch size checked between post edge and indication rod edge, and breach change mainly contains two kinds, and one is that indication rod moves and causes breach size variation, and one checks that post moves to result in breach size variation.
When indication rod moves, as shown in Figure 3, before indication rod moves, its breach edge is in A position, and after indication rod moves, its breach edge is in B position.Camera directly can obtain the displacement picture of indication rod edge movement thus calculate the change of breach size.
When checking that post moves, due to installation site restriction, the indication notch region that image collecting device photographs is stravismus angle, can not directly obtain checking post edge, as shown in Figure 4, before checking that post moves, its present position is C position in the drawings, and after checking that post moves, its present position is D position in the drawings.Owing to checking that post is a plane, edge is with reference to directly obtaining its displacement, so arrange laser transimitter, laser mark line is transmitted into the position checked with indication rod Plane intersects on post, due to the directional lighting characteristic of laser, the following feature of laser on projection thing, when after the displacement of inspection post, projection laser mark line thereon also can follow movement, as shown in Figure 5, laser mark line before inspection post moves is solid line E, laser mark line after inspection post moves is dotted line F, therefore the miles of relative movement of laser mark line is detected, also the miles of relative movement checking post is just detected.
Although the utility model has illustrated by reference to preferred embodiment and has described, but those of ordinary skill in the art should understand, the description of above-described embodiment can be not limited to, in the scope of claims, the various changes in form and details can be made.
