Abstract

The invention discloses a fiber-optic type pantograph carbon slide wear online partition real-time detection system, relates to a pantograph carbon slide wear detection and partition detection technology for railway locomotives, subway vehicles or EMUs, etc., and belongs to the field of train safety monitoring. In the present invention, the optical fiber wear sensor is pasted on the outside of the pantograph carbon slide or pre-buried inside the carbon slide, and the wear belt is divided into N wear areas by using the light transmission performance of the optical fiber and the laying position of the optical fiber. When wear occurs, it will cause Corresponding to the breakage of the optical fiber in the wear area, the light transmission performance is damaged and disappears. Through the statistical analysis of the breakage of the optical fiber in different wear areas, the wear value of the measured object and the wear area are given. The invention can realize the on-line, real-time and full-range dynamic detection of the wear of the pantograph carbon sliding plate, and can realize quantitative and positioning detection of the wear area. The invention has high precision, strong anti-interference ability, long service life and low cost, can provide basis for automatic lifting bow and carbon slide plate replacement, and supports the analysis of pantograph-catenary relationship at the same time.

Description
