Abstract
The utility model relates to a crack detecting device for a train track. The crack detecting device comprises a data processor. The data processor is connected with a displayer, a keyboard and an image data high-speed compression storage system. The image data high-speed compression storage system is connected with a controller. The controller is connected with a differential interference optical imaging system, a light source and a distance detector. The differential interference optical imaging system is arranged over the track. By adopting a non-contact lossless detecting technology, the crack detecting device is capable of automatically detecting the shapes, the sizes and distribution of cracks on the surface of the train track. Compared with manual visual check, the crack detecting device is high in detecting speed, detecting precision, resolution and the like. An equipment auxiliary data processing software automatically establishes a track crack detecting database based on multiple detecting results. According to the shapes, the sizes, the distribution and the changing progress of the cracks and combining with the previous experience, the positions of the track segments needing maintenance and maintenance priority are automatically marked in eye-catching colors.
Description
Technical field
The utility model relates to a kind of train rail crack detection equipment.
Background technology
After the train rail is long between in use, passed through the wearing and tearing of train wheel and exposing to the weather of physical environment, crackle will occur, in order to guarantee traffic safety, rail maintenance personnel need regular rail to be carried out artificial inspection.But the efficient of hand inspection is lower, and many modes by visual examination, often can omit the invisible crackle of some naked eyes.Tool using beats its firm degree of test to rail sometimes, and this mode also can be brought certain damage to rail.
The utility model content
The utility model proposes a kind of train rail crack detection equipment, adopt noncontact, lossless detection technology, automatically detect shape size and the distribution situation of railway road track surface crackle, remedied weak point of the prior art.
The technical solution of the utility model is achieved in that
A kind of train rail crack detection equipment, comprise data processor, described data processor is connected with display, keyboard and view data high speed compression storage system, described view data high speed compression storage system is connected with controller, be connected with differential interference optical imaging system, light source and range finder on the described controller, described differential interference optical imaging system be positioned at rail directly over.
The beneficial effects of the utility model are: adopt noncontact, lossless detection technology, automatically detect shape size and the distribution situation of railway road track surface crackle.Inspection is compared with artificial visual, and this equipment has that detection speed is fast, accuracy of detection is high and the feature such as resolution is high.Equipment ancillary data process software is set up rail crack detection database automatically based on measurement result time and again.According to shape size, distribution situation and the crackle change procedure of crackle, in conjunction with previous experiences, with the conspicuous color automatic Calibration need repairing the highway section the position and the maintenance relative importance value.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structured flowchart of the described train rail of the utility model embodiment crack detection equipment.
Among the figure:
1, data processor; 2, display; 3, keyboard; 4, view data high speed compression storage system; 5, controller; 6, differential interference optical imaging system; 7, light source; 8, range finder; 9, rail.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the described train rail of the utility model embodiment crack detection equipment, comprise data processor 1, described data processor 1 is connected with display 2, keyboard 3 and view data high speed compression storage system 4, described view data high speed compression storage system 4 is connected with controller 5, be connected with differential interference optical imaging system 6, light source 7 and range finder 8 on the described controller 5, described differential interference optical imaging system 6 be positioned at rail 9 directly over.
The described train rail of the utility model embodiment crack detection equipment in the course of the work, the signal of controller 5 receiving range sensors 8 is measured area according to a frame, determines the acquisition time of next frame measurement image, and the generation trigger pip, feed back to differential interference optical imaging system 6.Differential interference optical imaging system 6 directly gathers the differential signal of rail 9 images.Compare with common rail surface image, be distributed with the place of sudden change at rail, can export very strong signal.On the contrary, rail do not have the damage the place, can export very weak signal.So this system can detect rail crackle scar easily, signal to noise ratio (S/N ratio) is higher than normal image.The differential map picture of view data high speed compression storage system 4 continuous acquisition video cameras, and sequentially carry out the Fast Compression storage.Data processing centre (DPC) sequentially reads the picture signal of storage, adopts the independent development analytical algorithm, and automatic decision has flawless.After detecting crackle, sew up function by consecutive image, demarcate the position that this crackle occurs.Simultaneously, crack distribution and crack depth are carried out analyzing and processing, provide the final decision result.The arrangement various information rationally shows crackle actual distribution two and three dimensions result at the interface, near zone crackle situation, and the relevant informations such as resume appear in this highway section, place crackle, for further reference judgement of technician.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
