METHOD AND DEVICE FOR DETECTING PANTOGRAPH BOUNCE

摘要

PROBLEM TO BE SOLVED: To provide a highly precise method and device for detecting a pantograph bounce, which eliminates an influence of ultraviolet from a fluorescent lamp, a mercury lamp, or a signal lamp, and thereby can detect only ultraviolet light from arc light due to the pantograph bounce between a trolley wire and a slider.;SOLUTION: The method includes: (1) detecting the pantograph bounce by selecting and measuring a shorter wavelength ultraviolet light than that of the mercury lamp; (2) verifying current location data showing a traveling location of a vehicle with reference location data showing a location affected by disturbance light, and measuring no ultraviolet at a point affected by the disturbance light; (3) and detecting and measuring the pantograph bounce by selecting and measuring ultraviolet light having a shorter wavelength than that of the mercury lamp, verifying the current location data showing the traveling location of the vehicle, with the reference location data showing the location affected by the disturbance light, and stopping the pantograph bounce detection in the point affected by the disturbance light, based on the comparison results.;COPYRIGHT: (C)2012,JPO&INPIT
