Abstract
The utility model provides a steel rail dynamic displacement detection system which has high detection precision and is convenient to operate. The steel rail dynamic displacement detection system comprises a calibration device located on a steel rail, a displacement observation pile fixed on the ground, an imaging device fixed on the displacement observation pile and a processor which is connected with the imaging device and used for analyzing a steel rail creepage distance, wherein the imaging device can shoot the calibration device. The steel rail dynamic displacement detection system employs a photoelectric image method to detect steel rail creepage; the calibration device is located on the steel rail, and a mark is recorded; the imaging device is fixed on the displacement observation pile having a certain distance from the steel rail and taken as a static reference point; the imaging device continuously shoots a mark position of the steel rail; after displacement amount represented by each pixel at the calibration device is calibrated, the calibration device on the steel rail in pictures is recorded and compared though the processor, so vertical creepage amount of the steel rail is figured out by calculation. The steel rail dynamic displacement detection system has advantages of simple structure, high detection precision and convenient operation.
Description
Technical field
The utility model relates to a kind of detection system, especially a kind of rail dynamic displacement detecting system.
Background technology
For the detection of rail creeping, do not have special instrument at present, need to manually measure, precision is low, operation inconvenience.
The utility model content
The utility model provides a kind of accuracy of detection high, easy to operate rail dynamic displacement detecting system.
Realize the rail dynamic displacement detecting system of the utility model purpose, comprise the caliberating device that is positioned on the rail, be fixed on displacement observation stake on the ground, be fixed on the imaging device in the displacement observation stake, described imaging device can be taken caliberating device, the processor that is used for analyzing the rail creeping distance that links to each other with described imaging device.
Described caliberating device is any physical sign of red lacquer mark or luminotron or known distance.
Described caliberating device bonding or magnetic attraction or otherwise be fixed on the rail.
The distance of each pixel representative of described rail realizes that by caliberating device the effect of caliberating device is the corresponding rail displacement of each pixel of demarcating on the imaging device.
The beneficial effect of a kind of rail dynamic displacement detecting system of the present utility model is as follows:
A kind of rail dynamic displacement detecting system of the present utility model, adopt the photoelectric image method to detect creeping of rail, on rail, carry out mark with caliberating device, imaging device is fixed on apart from rail to be had in the displacement observation stake of certain distance as motionless reference point, and imaging device is taken pictures to the rail mark position continuously; After demarcating the caliberating device place displacement of each pixel representative, record, compare by the caliberating device of processor to rail in the image, and then calculate the vertically amount of creeping of rail; Simple in structure, accuracy of detection is high, easy to operate.
Description of drawings
Fig. 1 is the structural representation of a kind of rail dynamic displacement detecting system of the present utility model.
Embodiment
As shown in Figure 1, a kind of rail dynamic displacement detecting system of the present utility model, comprise the caliberating device 2 that is positioned on the rail 1, be fixed on displacement observation stake 4 on the ground, be fixed on the imaging device 3 in the displacement observation stake 4, described imaging device 3 can be taken caliberating device 2, the processor 5 that is used for analyzing the rail creeping distance that links to each other with described imaging device 3.
Described caliberating device 2 is red lacquer mark or luminotron.Described caliberating device 2 bondings or magnetic attraction are on rail.
Imaging device is fixed in the displacement observation stake, then the distance at the caliberating device place on elder generation's uncalibrated image on the rail of each pixel representative resolves caliberating device namely can accurately be measured caliberating device in the variation of the centre coordinate of imaging device vertical and horizontal displacement.Adopt high-speed CCD can measure train through the Vibration Condition of out-of-date rail under load action.Measurement data can adopt wired or wireless mode to transmit.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineering technical personnel in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
