Title:
TROLLEY WIRE DEVIATION SENSOR
Document Type and Number:
Japanese Patent JPH08193808
Kind Code:
A
Abstract:
PURPOSE: To reduce a measuring error of a deviation in the direction of track width of a trolley wire and accurately detect it.
CONSTITUTION: An image sensor 12 is set in the upper part of a pantagraph provided with a car to be detected and measured. The image sensor 12 arrays light receiving elements for measuring an emission element (LED) and the intensity of reflected light in the direction of the width of a track, and they are opposed to be held at regular intervals for a trolley wire 5. When the position of the trolley wire 5 is confirmed by the image sensor 12 and a deviation from a reference position is measured, the error of measurement accuracy is lowly controlled, and accurate deviation detection can be performed.
