OPTICAL SYSTEM FOR DETECTING ABRASION WEAR OF TROLLEY WIRE, AND DEVICE FOR MEASURING ABRASION WEAR OF TROLLEY WIRE

摘要

PROBLEM TO BE SOLVED: To provide an optical system for detecting abrasion wear of a trolley wire and a device for measuring the abrasion wear of a trolley wire that are small in device height and minimized.;SOLUTION: This optical system for detecting abrasion wear of the trolley wire includes a light projection unit that generates slit-like projection light, with a plurality of monochromatic light sources arranged in the rail crossing direction and radiates it to a sliding surface of the trolley wire, a first light receiver, and a second light receiver for receiving reflected light from the trolley wire via a filter for eliminating the wavelength range of monochromatic light. The optical system acquires a detection signal, regarding the sliding surface by using the difference between light receiving signals of two light receivers.;COPYRIGHT: (C)2011,JPO&INPIT
