Description
Technical field
The present invention relates to a kind of high speed train wheel track relative position and measure in real time warning device, relative position between can Real-Time Monitoring wheel track, by data analysis and judgement, can give the alarm to train driver, train driver operation train slows down in good time or stops, thus the generation of prevention derailment accident.
Background technology
Railway transportation is the main artery of national economy.In modern wheel-track type railway traffic transportation, in train operation, the accident of derailing often occurs voluntarily, and the ratio that derail accident accounts in the total accident of railroad train is the highest, is one of major accident of harm safety of railway traffic.In order effectively to prevent the generation of derail accident, on train, need to increase the device that between a Real-Time Monitoring wheel track, relative position also can be reported to the police, when the relative position between wheel track exceedes alarm value, report to the police, train slows down in good time or stops, thus trouble-saving generation.And do not have the wheel track relative position for train specially to measure in real time the device that also can report to the police at present.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of high speed train wheel track cross travel detection module, after it adopts high-speed camera and light source to gather wheel track image, on high-end industrial control computer, carry out image processing, data computational analysis and judgement, and then measure wheel track relative position.This device precision is high, measures in real time, and speed is fast, and safety is good, and stability is high, easy to use.
The present invention solves the technical scheme that its technical matters takes: it comprises:
Digitized image acquisition module: comprise high speed CCD camera (3), camera lens (4), light source (1) and protective case (2).High speed CCD camera (3), camera lens (4) and light source (1) complete the accurate collection of wheel track image at front end, and be transported to the wheel track relative position computing module of rear end, the impact that protection (2) can effectively protect high speed CCD camera (3), camera lens (4) and light source (1) not caused by the severe environmental conditions such as muddy water, sand or frost;

Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is schematic diagram of the present invention.
The specific embodiment
The present invention includes digitized image acquisition module, wheel track relative position computing module, display module, communication module and alarm module.
Digitized image acquisition module comprises high speed CCD camera 3, camera lens 4, light source 1 and protective case 2.As shown in Figure 1.High speed CCD camera 3, camera lens 4 and light source 1 complete the accurate collection of wheel track image at front end, and are transported to the wheel track relative position computing module of rear end.The impact that protective case can effectively protect high speed CCD camera 3, camera lens 4 and light source 1 not caused by the severe environmental conditions such as muddy water, sand or frost.Ccd video camera selects the CCD of 1/3 inch of 3 use, and resolution is 1392*1040.Digitized image acquisition module is arranged on train bottom position, high speed CCD camera 3 and camera lens 4 are 750mm to the ranging coverage of wheel track by actual measurement, select after the camera lens that 1/3 inch, focal length are 20mm, survey precision is about 0.1mm, imaging precision is high, good imaging quality, picking rate is fast, safe and reliable.
Wheel track relative position computing module is selected high-end computer.This module is connected with digitized image acquisition module with network interface by serial ports, the operation of digital control image capture module and stopping, and receive the wheel track graphicinformation that digitized image acquisition module obtains, complete after the calculating of processing to image and data, for display module show, communication module carries out communication, and control alarm module and report to the police.Wheel track relative position computing module is determined wheel and track by the method for images match, to the Image Segmentation Using processing in matching area, find out and describe the fitting a straight line of describing track trend, find out again and describe the fitting a straight line of describing wheel trend, by position relationship between the two, determine the position relationship of wheel and track, for accurately measuring two parameters that fit straight line, avoid, because image is processed the error that integer level computing and image resolution ratio are brought, also having adopted sub-pix subdivide technology to improve operational precision.The wheel track relative positional accuracy calculating is like this high, good stability.
Display module is connected with wheel track relative position computing module, for the position data and the state that calculate are carried out to visualization processing, for train driver, watches data, very clear, directly perceived.
Communication module is connected with wheel track relative position computing module, completes communicating by letter of this device and miscellaneous equipment on train, the wheel track station-keeping data calculating can be transferred on miscellaneous equipment and carry out secondary use, is convenient to sharing of information, easy to use.
Alarm module is controlled by wheel track relative position computing module, when the relative position between wheel track exceedes alarm value, reports to the police.Man-machine communication is good.
This device precision is high, measures in real time, and speed is fast, and safety is good, and stability is high, easy to use.
