Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Apply example, the every other embodiment that those of ordinary skill in the art are obtained without making creative work, all
Belong to the range of the utility model protection.
In conjunction with shown in Fig. 1 and Fig. 2, a kind of underbody for bow net on-line monitoring that the utility model embodiment provides compensates
Device, including the compensation device ontology 2 in underbody is set, compensation device ontology 2 is mounted on the bottom of rail vehicle 1 by hanger 5
Portion, compensation device ontology 2 are equipped with image capture device 22 and light source 21, which can be visible images
Collecting device or infrared image acquiring equipment, when image capture device 22 is infrared image acquiring equipment, light source 21 should also select
Take infrared light light source；Light source 21 is radiated at obliquely on rail 4, and irradiation formation includes longitudinal profile of 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；Figure
As the visual field of collecting device 22 completely or partially covers the structure reflected light, and the acquisition direction of image capture device 22 and steel
The axial direction of rail 4 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 the actual profile compared to 4 side of I-shaped rail is deformed.
The present embodiment additionally provides a kind of underbody compensation method for bow net on-line monitoring, and this method is, on rail 4
Irradiation formation includes the structure reflected light of the longitudinal profile of rail 4, and structure reflection is acquired 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 the 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
It will change, therefore horizontal and vertical contracting can also occur for the 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 the compensating parameter monitored at this time to bow net, that is to say, that the S-shaped of each 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 can also be obtained with record by three-dimensional software simulated implementation in 1 actual motion of rail vehicle.Thus
To provide offset data with analysis for the monitoring of bow net geometric parameter by the monitoring to S-shaped structure reflected light.
The utility model can directly be that bow net geometric parameter monitoring feedback is inclined about car body by way of Image Acquisition
The offset data of shifting amount, 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 easy
It breaks down；And the analysis of underbody image can share an image processing apparatus with processing with the bow net monitoring modular 3 of roof,
Therefore simplify structure, reduce cost, 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 is sent out is concentrated, and brightness is high,
It is possible thereby to image capture device 22 is made to 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 is sent out is irradiated along the longitudinal direction of rail 4, and the light that light source 21 is sent out
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 of 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 the institute of such image capture device 22, which changes, is only dependent upon image
The visual angle change of collecting device 22, 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 can't influence rail
Road vehicle 1 passes through performance.
In some embodiments, top of the image capture device 22 between both sides rail 4, such installation position is not
Can increase the profile of 1 both 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 of both sides 4 respectively, i.e. each group of image capture device 22 and light source 21 correspond to monitoring side rail 4,
It can be with the rail 4 of Simultaneous Monitoring both 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 the image capture device 22 and the siding track that are located at curve inner side can be than usual
Big, if so feeding back corresponding compensating parameter with this, it will cause larger errors, and just due to being synchronized to both sides rail 4
Monitoring, therefore can know that rail spacing at this time is increased by two groups of image capture devices 22, that is, know current vehicle
It is excessively curved, eventually by the comprehensive analysis to 22 acquired image of both sides image capture device, can to compensating parameter into
Row is corrected, 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 underbody 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：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc.
With replacement；And these modifications or replacements, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
