Description

Track condition on-line monitoring method based on laser monitoring

Technical field

The present invention is track condition on-line monitoring method based on laser monitoring, belongs to rail vehicle transportation technical field.

Background technology

In rail vehicle transportation, owing to operation, natural disaster, track vibration and the abrasion of vehicle, the sedimentation of roadbed become Changing, can cause the change of relative spacing between two tracks, the change of level, the change of track fastening facilities, these become Track traffic safety can be brought harm by change factor, and surveys the state status understanding employing manual site of track at present Examination, or carry corresponding instrument and meter by test vehicle and be in operation and test, so have monitoring poor real, to prominent Send out property orbit parameter change can not find in time and report to the police, test job amount and the big defect of cost；Akin with the present invention Correlation technique is, the patent No.: 201010272150.X, track on-line monitoring method, wherein describes and solves the one of the problems referred to above A little technical schemes, but there is also some defects, its method of work is complex, in actual applications, is typically due to wanting of application Ask, use some brief technical methods i.e. can meet needs.

Summary of the invention

In view of the foregoing, it is an object of the invention to provide a kind of track condition on-line monitoring side based on laser monitoring Method, it is achieved change, the change of level, the change of track fastening facilities and the track interior of track relative spacing is cracked On-line monitoring, have monitoring real-time good, to sudden orbit parameter change can find in time and report to the police, test job amount and The feature of low cost.

For reaching above-mentioned purpose, the present invention introduces a kind of track condition on-line monitoring method based on laser monitoring, and it is special Levy and be, measure each distance prison by the multiple laser distance detector scanning track outer rims being arranged on detecting of railway point both sides Survey data, distance Monitoring Data and the corresponding address code of the current orbit test point of acquisition are sent to by telecommunication transmission system Orbit monitoring central apparatus carries out storing, analyze and comparing with corresponding historical data, draws and passes through display and control terminal shows Show current relative spacing, level and the comparison difference in change with historical data between the track of respective carter test point Value, when when relative spacing, level and exceeding set respective value with the comparison of historical data change difference, orbit monitoring Central apparatus produce alarm signal, and by alarm signal by telecommunication transmission system be sent to display and control terminal show And sound and light alarm.

The operation principle of the present invention and beneficial effect

Scan rail profiles under control of the microprocessor measure by being arranged on multiple laser distance detectors of track both sides Each range data information, measures data by the distance of current orbit test point and corresponding address code is passed by telecommunication transmission system Delivering to orbit monitoring central apparatus carry out storing, analyze and contrast corresponding historical data, according to distance test data, conversion is overstepped the limit Road formal parameter and the relative and respective distances parameter of test benchmark point, owing to precision of laser ranging is high, therefore can be to track Small conversion is measured, draw and pass through display and control terminal demonstration current orbit each test point relative spacing, Level and the comparison with historical data change difference, when relative spacing, level and the comparison with historical data change When difference exceeds set corresponding difference, orbit monitoring central apparatus produces alarm signal, and is sent to show by alarm signal Showing and control terminal and carry out acousto-optic and display alarm, described display and terminal include fixed terminal, mobile terminal, traffic control Signaling system terminal processed and traffic control signal display.
