The invention provides a pantograph sliding plate wear detection method and system, including a laser scanner and a pantograph sliding plate, and the laser scanner emits pulsed laser light longitudinally to the pantograph sliding plate, and receives reflected light to determine the pulse laser emission The first time and the second time of receiving the reflected light, obtain the time difference between emitting the pulse laser and receiving the reflected light; then obtain the speed of the laser, and determine the distance value between the laser scanner and the corresponding reflecting position based on the time difference; Calculate the difference between the distance value and the standard distance to obtain the distance deviation value; use the distance deviation value to calculate the depression value of the real position on the pantograph slide; change the scanning angle of the laser scanner to determine all the real positions on the pantograph slide The sag value of the pantograph sliding plate is generated according to the real position sorting to determine the wear degree of the pantograph sliding plate. The invention has the beneficial effects of being able to realize real-time monitoring of the wearing condition of the pantograph sliding plate.
Description
technical field [0001] The invention relates to the field of rail transportation, in particular to a method and system for detecting wear of a pantograph slide plate. Background technique [0002] The sliding plate structure is the key component of the pantograph sliding plate. During use, it will be worn due to friction with the catenary. The size and uniformity of the wear will directly affect the electrical performance, reaching a certain wear, or the unevenness of the wear exceeds Standard ranges then require immediate replacement. [0003] At present, the detection of the slide plate structure mainly adopts manual inspection, by visually observing the defects on the surface of the carbon slider structure, and measuring by selecting three points with the most worn areas; there are also automatic detection methods through images, using LED or laser as a supplementary light source , through the high-speed high-definition camera to take pictures of the pantograph skateboar...
