Abstract

The invention discloses a track state online monitoring method based on vibration monitoring. The track state online monitoring method based on vibration monitoring is achieved through a communication transmitting system, track monitoring center equipment, vibration sensors, microprocessors and communication modules, and cracks and deformation generated in tracks can be monitored online. The track state online monitoring method based on vibration monitoring has the advantages that monitoring real-time performance is good, sudden track parameter changes can be found and alarmed in time, and the testing working load and cost are low.

Description

Track condition on-line monitoring method based on vibration monitoring

Technical field

The present invention is track condition on-line monitoring method based on vibration 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, track interior can be caused to crack and deformation, track traffic safety can be brought harm by these changing factors, and mesh Before the state status of track understood use manual site's test, or be in operation by test vehicle and test, so can There is monitoring poor real, the change of sudden orbit parameter can not be found in time and reports to the police, test job amount and big the lacking of cost Fall into；Correlation technique akin with the present invention is, the patent No.: 201010272150.X, and track on-line monitoring method is wherein introduced Solving some technical schemes of the problems referred to above, but there is also some defects, its method of work is complex, applies in reality In, it is typically due to the requirement of application, uses 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 vibration 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 vibration monitoring, comprises There are vibrating sensor, communication system, orbit monitoring central apparatus and control terminal, it is characterised in that by being arranged on multiple rail Multiple vibrating sensors on the track of road test point obtain the track vibration Monitoring Data of each detecting of railway point current, will be each Individual track vibration Monitoring Data and corresponding address code by telecommunication transmission system be sent to orbit monitoring central apparatus carry out storing, Analyze and compare with corresponding historical data, draw and pass through display and control terminal demonstration currently at each corresponding detecting of railway The vibration parameters of track of point, the vibration difference parameter between vibrating sensor and the comparison change difference with historical data, when Vibration propagation parameter between vibration parameters, detecting of railway point and with the comparison of corresponding historical data change difference beyond set Respective value time, orbit monitoring central apparatus produces alarm signal, and is sent to show by telecommunication transmission system by alarm signal Show and control terminal and carry out showing and sound and light alarm.

The operation principle of the present invention and beneficial effect

Due to vehicle operation in orbit, track can produce fast vibration and with wheel by produce upper and lower displacement, or because of Vibration parameters can be brought impact, track interior to have crackle or deformation by environmental hazard, track fastening facilities state and roadbed state, The propagation characteristic of vibration wave can be produced impact so that the transmission signal of vibration wave produces corresponding change, is arranged on multiple rail Multiple vibrating sensors on the track of road test point under control of the microprocessor, by the track of each detecting of railway point current Vibration information data are sent to orbit monitoring central apparatus by telecommunication transmission system and carry out storing, analyze and contrast history number According to, draw and by controlling terminal demonstration current orbit between the vibration parameters, detecting of railway point of each detecting of railway point Vibration propagation parameter and change difference with the comparison of historical data, Vibration propagation parameter between vibration parameters, test point and When exceeding set respective value with the comparison situation of change of corresponding historical data, orbit monitoring central apparatus produces alarm signal Number, and by alarm signal by telecommunication transmission system be sent to display and control terminal carry out acousto-optic and display alarm, described Display and terminal include fixed terminal, mobile terminal, traffic control signal system terminal and traffic control signal display, this Sample be achieved that track interior is cracked and deformation situation real time on-line monitoring with and alarm.
