Multifunctional track detection system

Abstract

The invention provides a multifunctional track detection system. The multifunctional track detection system comprises a laser scanning receiving module, an inertia acquisition module, a vision acquisition module and a control module, the laser scanning receiving module comprises a CCD camera and a linear structure light laser, structure light emitted by the linear structure light laser is projected to the surface of the track, and the CCD camera collects a laser irradiation image of the surface of the track; the laser scanning receiving system is used for detecting static parameters and abrasion of a third rail and a steel rail; the inertia acquisition module is used for detecting the irregularity of the steel rail; the visual acquisition module comprises a visible light camera, a light source and a light source irradiation track, and the visible light camera is used for acquiring visible light irradiation images on the track surface; the visual acquisition module is used for track surface defect detection; and the control module is used for receiving the image information and carrying out data processing to obtain a comprehensive detection result. The beneficial effects of the system are that the system achieves the simultaneous detection of all tracks through non-contact detection, obtains the comprehensive track detection data, and improves the detection efficiency.

Description

technical field [0001] The present disclosure relates to the technical field of track detection, in particular to a multifunctional track detection system. Background technique [0002] The geometric dimension deviation of the railway track directly affects the stability, comfort and safety of the train, and even threatens the life and property safety of passengers. Moreover, as the speed of the train becomes faster and faster, the requirement for the stability of the track is higher and higher, and the accuracy of the evaluation of the geometric state of the track is also higher and higher. [0003] The existing measurement methods of track geometric parameters are mostly carried out independently, and the steel rail and the third rail are carried out separately, which cannot evaluate the track geometric state as a whole. Moreover, the state measurement of the existing rails all adopts contact means, and the mechanical accumulation error is relatively large, which seriousl...

Problems solved by technology

[0003] Most of the existing measurement methods of track geometric parameters are carried out independently, and the steel rail and the third rail are carried out separately, which cannot evaluate the track geometric state as a whole

Moreover, the state measurement of the existing rails is by contact means, and the mechanical accumulation error is relatively large, which seriously affects the evaluation results of the geometric state of the rail.
