PROBLEM TO BE SOLVED: To provide a railway control system which can detect a position of a train without using a track circuit without causing a great cost increase, and has high resistance against electromagnetic noise.SOLUTION: A railroad crossing control system includes an optical cable (11) laid along a railway track (12), light detection means (21) which detects scattered light in a light source that is connected to the optical cable and emits a laser beam to a core of the optical cable, and in the core, a frequency analysis part (22) which frequency-analyzes an optical signal detected by a photodetector, and control means (30) which detects presence of an object based on a signal from the frequency analysis part, where the optical cable is disposed in a region intended to detect presence of the object in the railway track so that a multiple loop surrounding the object is formed.SELECTED DRAWING: Figure 1

    【課題】大幅なコストアップを招くことなく、軌道回路を使用せずに列車の位置を検出することができるとともに電磁ノイズに対する耐性の高い鉄道制御システムを実現する。【解決手段】鉄道軌道(12)に沿って敷設された光ケーブル(11)と、光ケーブルに接続され該光ケーブルのコアに対してレーザ光を出射する光源およびコア内の散乱光を検出する光検出手段(21)と、光検出器が検出した光信号を周波数解析する周波数解析部(22)と、周波数解析部からの信号に基づいて対象物の存在を検出する制御装置(30)とを備えた鉄道制御システムにおいて、前記光ケーブルを、鉄道軌道において対象物の存在を検出したい領域で、当該対象物を囲む多重ループを形成するように配設した。【選択図】図1
