To detect, using a compact and simple structure, the mutual separation of a plurality of overhead wires with high accuracy at a position where one of the overhead wires is displaced by a prescribed amount.SOLUTION: A light projection unit irradiates a plurality of overhead wires 1a, 1b installed in the sky above rails with measurement light spread in belt form in the width direction of the rails. A plurality of light receiving units 4 are provided in the width direction of the rails with a space therebetween, respectively receive reflected light of the measurement light having been reflected by all or some of the plurality of overhead wires 1a, 1b and output a measurement signal that indicates the contours of the overhead wires 1a, 1b. The light receiving units 4 are installed partially overlapping each other's measurement visual field so that all of the plurality of overhead wires 1a, 1b within a predetermined measurement range fit within the range of measurement visual field of at least one of the light receiving units 4. A processing device 5 processes the measurement signals outputted from the plurality of light receiving units 4 on the basis of information pertaining to the installed position of each light receiving unit 4, and detects the mutual separation of the plurality of overhead wires 1a, 1b and the displacement amount of each overhead wire 1a, 1b.SELECTED DRAWING: Figure 1
【課題】小型かつ簡易な構成で、複数の架線の相互離隔を、いずれかの架線が所定量だけ偏位した位置において、高精度に検出する。【解決手段】投光ユニットは、レールの上空に設置された複数の架線1a,1bへ、レールの幅方向に帯状に広がった測定光を照射する。複数の受光ユニット4は、レールの幅方向に離して設けられ、測定光が複数の架線1a,1bの全部又は一部で反射された反射光をそれぞれ受光して、各架線1a,1bの輪郭を示す測定信号を出力する。各受光ユニット4は、予め定めた測定範囲内にある複数の架線1a,1bの全てが、少なくともいずれかの受光ユニット4の測定視野の範囲内に入る様に、互いの測定視野を一部重ねて設置され、処理装置5は、各受光ユニット4の設置位置の情報に基づき、複数の受光ユニット4から出力された測定信号を処理して、複数の架線1a,1bの相互離隔、及び各架線1a,1bの偏位量を検出する。【選択図】図1
