Description
Technical field
The present invention is track condition on-line monitoring method based on ultrasonic conducting monitoring, belongs to rail vehicle transportation technology neck
Territory.
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；At correlation technique
In, describe the scheme to the vibration wave transmission state detecting track, but wherein using vibration generation source is in traveling
Train, such vibration source has certain randomness, therefore complex in the analyzing and processing of data.
Summary of the invention
In view of the foregoing, it is an object of the invention to provide a kind of track condition based on ultrasonic conducting monitoring to supervise online
Survey method, it is achieved crack track interior and the on-line monitoring of deformation, has monitoring real-time good, joins sudden track
Number 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 ultrasonic conducting monitoring,
Including supersonic generator, supersonic detector, communication system, orbit monitoring central apparatus and control terminal, its feature exists
In, each supersonic generator sends ultrasound wave in the time period set to track, and the detection of each supersonic detector receives super
Sound wave and the ultrasonic signal of reception is given digitized processing obtain each track conduction detection data, each track is conducted
The address code of the supersonic detector of detection data and correspondence is sent to orbit monitoring central apparatus by telecommunication transmission system and enters
Row storage, analyze and compare with corresponding historical data, draw and pass through display and control terminal demonstration currently correspondence each
The track conduction detection data of detecting of railway point and the comparison change difference of historical data, when track conduction detection data are with corresponding
When the comparison change difference of historical data exceeds set respective value, orbit monitoring central apparatus produces alarm signal, and will
Alarm signal is sent to display by telecommunication transmission system and control terminal carries out showing and sound and light alarm.
Track condition on-line monitoring method based on ultrasonic conducting monitoring of the present invention, it is also possible to be that its feature exists
In, at same monitoring ultrasonic point, or on the same one steel rail of same monitoring ultrasonic point, supersonic generator and ultrasound wave
Receptor is time-division method of work；That is: the work when supersonic generator at same place is different from ultrasonic receiver, this
Sample can avoid the near-end between supersonic generator and ultrasonic receiver to disturb, it is ensured that test is correct.The work of the present invention
Principle and beneficial effect
When track interior has crackle or deformation, the propagation condition of ultrasound wave can be produced impact, arrange in orbit is multiple super
Sonic generator and multiple ultrasonic receiver under control of the microprocessor, carry out transmission and the reception of ultrasound wave respectively,
Same monitoring ultrasonic point, or same detection monitoring ultrasonic point is on same one steel rail, supersonic generator and ultrasound wave
Receptor is time-division method of work, is achieved in that the track ultrasound wave conducts information data of each orbital segment, and each is ultrasonic
Ripple conducts 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 control terminal demonstration current orbit the ultrasound wave of each orbital segment spread state indicate and with history number
According to comparison change difference, when ultrasound wave conducts information data and with the comparison situation of change of corresponding historical data exceed set
Respective value time, orbit monitoring central apparatus produces alarm signal, and is sent to show by telecommunication transmission system 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, thus achieve the change to track relative spacing, level
Change, the change of track fastening facilities and track interior crack the real time on-line monitoring of situation with and alarm.
