Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Referring to figs. 1 and 2, a kind of vehicle bottom for bow net on-line monitoring provided in an embodiment of the present invention compensates dress
It sets, the compensation device ontology 2 including vehicle bottom is arranged in, compensation device ontology 2 is mounted on the bottom of rail vehicle 1 by hanger 5,
Compensation device ontology 2 is equipped with image capture device 22 and light source 21, which can be visible images and adopt
Collect equipment or infrared image acquiring equipment, when image capture device 22 is infrared image acquiring equipment, light source 21 should also be chosen
Infrared light light source；Light source 21 is radiated at obliquely on rail 4, and irradiation forms longitudinal profile including rail 4 on rail 4
Structure reflected light, that is to say, that the outer contour shape of 4 side of rail can be embodied in structure reflected light, i.e., it is substantially S-shaped；Image
The visual field for acquiring equipment 22 completely or partially covers the structure reflected light, and the acquisition direction of image capture device 22 and rail
4 axial direction is angled therebetween, therefore also substantially S-shaped from the collected structure reflected light of the visual angle of image capture device 22 institute, but
Actual profile compared to I-shaped 4 side of rail is deformed.
The present embodiment additionally provides a kind of vehicle bottom compensation method for bow net on-line monitoring, and this method is, on rail 4
Irradiation forms the structure reflected light including the longitudinal profile of rail 4, acquires structure reflection from the direction to form an angle with rail 4
The image of light finds out the image to match with collected structure reflected light image in image library, by the image to match institute
Corresponding transversal displacement and sidewinder the offset data that offset is monitored on-line as bow net.
In monitoring process, when lateral shift occurs for rail vehicle 1, image capture device 22 and monitored rail 4 it
Between distance change therewith, lateral scaling can also occur for S-shaped structure reflected light accessed by image capture device 22
Deformation；When rail vehicle 1 sidewinders offset, horizontal distance and vertical distance of the image capture device 22 relative to rail 4
Changes will occur, therefore horizontal and vertical contracting can also occur for S-shaped structure reflected light accessed by image capture device 22
Deformation is put, with the change of 1 offset of rail vehicle, image capture device 22 acquires the S-shaped structure reflected light with different view
Also different degrees of deformation can occur.
Image capture device 22 the S-shaped structure reflected light of each collected form can embody rail vehicle 1
A kind of specific posture, and then can determine at this time to bow net monitoring compensating parameter, that is to say, that the S-shaped of every kind of form
Structure reflected light is corresponding with one group of compensating parameter, and the S-shaped structure reflected light of different shape is corresponding with corresponding compensating parameter closes
The acquisition of system and record can also can be obtained by three-dimensional software simulated implementation in 1 actual motion of rail vehicle.Thus
To provide offset data with analysis by the monitoring to S-shaped structure reflected light for the monitoring of bow net geometric parameter.
The present invention can be directly bow net geometric parameter monitoring feedback about car body offset by way of Image Acquisition
Offset data, feedback accuracy is high, and speed is fast, and is not easily susceptible to the influence of the environmental factors such as landform, and stability is strong, is not susceptible to
Failure；And the analysis of vehicle base map picture and processing can share an image processing apparatus with the bow net monitoring modular 3 of roof, therefore
Simplify structure, reduce costs, offset data to the modified response speed of bow net monitoring data faster.
In some embodiments, light source 21 is 21 laser of linear light source, and the light that laser light source 21 issues is concentrated, and brightness is high,
It is possible thereby to make image capture device 22 collect the structure reflected light that rail profile is clear, resolution is high, therefore can be accurate
The S-shaped structure reflected light got under current visual angle.
Further, the Linear Laser that 21 laser of linear light source issues is irradiated along the longitudinal direction of rail 4, and the light that light source 21 issues
Vertical irradiation is to rail 4, therefore no matter what kind of lateral shift compensation device ontology 2 occurs and sidewinder offset, laser light source 21
The structure reflected light that formation is irradiated on rail 4 can keep vertical state, that is to say, that S-shaped structure reflected light itself is always
It will not occur flexible and tilt, the scaling of the collected sigmoid curve of such image capture device 22 institute, which changes, is only dependent upon image
The visual angle change of equipment 22 is acquired, therefore can more accurately feed back the transversal displacement of errant vehicle 1 and sidewinder offset,
And then greatly improve the accuracy of offset data.
In addition, compensation device ontology 2 is preferably higher than the axle of rail vehicle 1, therefore this compensation device will not influence rail
The passage capacity of road vehicle 1.
In some embodiments, top of the image capture device 22 between two sides rail 4, such setting position is not
Will increase the profile of 1 two sides of rail vehicle, and image capture device 22 acquire be rail 4 inside and top side, compared to rail
The outside in road, ambient light photograph is weaker, thus the extraction of structure reflected light influenced by bias light it is lower.
Compensation device ontology 2 is equipped with two groups of image capture devices 22 and light source 21, two groups of image capture devices 22 and light
Source 21 matches with the rail 4 of two sides respectively, i.e. each group of image capture device 22 and the corresponding monitoring side rail 4 of light source 21,
It can be with the rail 4 of Simultaneous Monitoring two sides, therefore when excessively curved, due to bend by two groups of image capture devices 22 and light source 21
Rail spacing is wider than the rail spacing of straight way, and the spacing of image capture device 22 and the siding track positioned at curve inner side can be than usual
It is big, so it will cause biggish errors if feeding back corresponding compensating parameter with this, and just due to synchronous to two sides rail 4
Monitoring, therefore can know that rail spacing at this time is to increase, that is, know and work as front truck by two groups of image capture devices 22
It is excessively curved, eventually by the comprehensive analysis to 22 acquired image of two sides image capture device, can to compensating parameter into
Row amendment, in order to avoid there is large error.
The present embodiment additionally provides a kind of bow net on-line monitoring system, which includes online for bow net as described above
The vehicle bottom compensation device of monitoring can accurately be obtained the offset parameter of vehicle by the compensation device, therefore bow net is supervised
More accurate bow net geometric parameter data can be obtained for survey.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features；
And these are modified or replaceed, technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution spirit and
Range.
