Description

The track on-line monitoring system

Technical field

The utility model is the track on-line monitoring system, belongs to track traffic transportation technology field.

Background technology

In the track traffic transportation, because the operation of vehicle, disaster, track vibration and wearing and tearing, the sedimentation of roadbed changes, falling rocks and foreign matter, can cause the variation of track relative spacing, the variation of level, track stops, the fastening facility of track changes and track inside cracks and deformation, these changing factors can bring harm to the track traffic transportation safety, adopt artificial on-the-spot test and at present the state status of track is understood, or be in operation by testing vehicle and test, it is poor to have the monitoring real-time like this, the defective that test job amount and cost are big can not be in time found and be reported to the police in sudden orbit parameter variation.

Summary of the invention

In view of the foregoing, the purpose of this utility model is to provide a kind of track on-line monitoring system, realization is to the variation of track relative spacing, the on-line monitoring that track stops, the fastening facility of track changes and track inside cracks that variation, falling rocks and the foreign matter of level cause, it is good to have the monitoring real-time, the characteristics that test job amount and cost are low can be in time found and be reported to the police in sudden orbit parameter variation.

For achieving the above object, the utility model is introduced a kind of track on-line monitoring system, it is characterized in that having a plurality of laser distance detectors, a plurality of vibratioies sensor, a plurality of displacement pickups, a plurality of microprocessors and communication module, orbit monitoring center and a plurality of demonstration and control terminal, the laser distance detector is arranged on the track both sides, vibration sensor and displacement pickup are arranged on the track both sides and contact with track, the laser distance detector, the monitor signal mouth of vibration sensor and displacement pickup and control end are connected with the control input/output terminal of microprocessor respectively, microprocessor and communication module, the orbit monitoring center, be connected by communication system between demonstration and the control terminal.

Principle of work of the present utility model is: measure each range data information by a plurality of laser distance detectors scan track profile under the control of microprocessor that is arranged on the track both sides, the distance of current detecting of railway point is measured data and corresponding address sign indicating number to be sent to the orbit monitoring center by telecommunication transmission system and to store, analyze and contrast corresponding historical data, according to the distance test data, converse the respective distances parameter of track formal parameter and relative and test benchmark point, because precision of laser ranging height, therefore can be to the small conversion of track, the track that falling rocks and foreign matter cause stops to be measured, draw and by showing and control terminal shows the relative spacing of current track in each test point, level reaches the relatively variation difference with historical data, work as relative spacing, level and during with relatively the changing difference and exceed the corresponding difference that sets of historical data, the orbit monitoring center produces alerting signal, and alerting signal is sent to shows and control terminal carries out acousto-optic and display alarm that described demonstration and terminal include fixed terminal, portable terminal, traffic control signal system terminal and traffic control signal telltale; Because vehicle operation in orbit, track can produce fast vibration and with wheel pass through the generation upper and lower displacement, or because of environmental hazard, fastening facility state of track and roadbed state can bring influence to vibration parameters and displacement parameter, there are crackle or deformation in track inside, can the propagation characteristic of vibration wave be exerted an influence, be arranged on a plurality of vibratioies sensor on the track of a plurality of detecting of railway points and a plurality of displacement pickup under the control of microprocessor, the track vibration of current each detecting of railway point and displacement information data are sent to the orbit monitoring center by telecommunication transmission system stores, analyze and the contrast historical data, draw and show the vibration parameters of current track at each detecting of railway point by control terminal, displacement parameter, vibration propagation parameter between the detecting of railway point reaches the relatively variation difference with historical data, work as vibration parameters, displacement parameter, vibration propagation parameter between the test point and when exceeding the respective value that sets with the comparison situation of change of corresponding historical data, the orbit monitoring center produces alerting signal, and alerting signal is sent to by telecommunication transmission system shows and control terminal carries out acousto-optic and display alarm, described demonstration and terminal include fixed terminal, portable terminal, traffic control signal system terminal and traffic control signal telltale have so just been realized the variation to the track relative spacing, the variation of level, the fastening facility of track changes and track inside cracks the real time on-line monitoring of situation and warning in time.
