To provide a train movement detection system which can detect a train movement without an auxiliary power supply when a train power supply is lost and also can detect it even when the train moves without wheel rolling because of train sliding and the like.SOLUTION: A train movement detection system S which detects a movement of a train 101 acquires a periphery picture of the train from an imaging unit 104, just after the system recovers from a non-communicative state in which an onboard device 102 that detects a train position based on information from a ground unit and a ground device 112 cannot communicate mutually, calculates movement detection information indicating whether the train moved from the non-communicative state time to the recovered time based on a comparison between the acquired picture and a picture for referencing and outputs the movement detection information to the onboard device.SELECTED DRAWING: Figure 1

    【課題】列車の電源断時に、補助電源を必要とせず列車の移動検知を行い得ると共に、滑走などにより車輪が回転せずに列車が移動した場合でも列車の移動検知を行う列車移動検知システムを提供する。【解決手段】列車101の移動を検知する列車移動検知システムSは、地上子からの情報をもとに列車の位置を検出する車上装置102と地上装置112とが通信できない状態からの復帰直後に、撮像部104から列車の周囲の画像を取得し、画像と照合用画像とを比較した結果に基づいて、通信できない状態となってから復帰するまでに列車が移動したか否かを示す移動検知情報を算出し、移動検知情報を車上装置へ出力する。【選択図】図1
