PROBLEM TO BE SOLVED: To provide a train approach warning system capable of securely warning when a train approaches.SOLUTION: A train approach warning system comprises: an on-vehicle device 3 including a communication part for transmitting longitude information of a train detected by a longitude detector; a central device 1 for converting the longitude information received from the on-vehicle device 3 to a one-dimensional information, and creating information to be transmitted, on the one-dimensional position and the like if the one-dimensional information matches on-rail information of a train, or on a failure if it does not match; and a mobile terminal 2 for detecting a current position thereof using the longitude detection part, calculating a distance between the current position and the train on the basis of the one-dimensional position information received from the central device 1 through the communication part, and issuing a warning when the distance becomes a predetermined distance. The central device 1 provides a predetermined area at a boundary part where the on-rail information is switched, and refrains from determining the matching between the one-dimensional position information and the on-rail information of the train, in the predetermined area.SELECTED DRAWING: Figure 1

    【課題】列車が接近した場合に確実に警報する列車接近警報システムを提供する。【解決手段】緯度経度検出部により列車の緯度経度情報を検出して通信部により送信する車載装置3と、車載装置3から受信した緯度経度情報を一次元位置情報に変換し、一次元位置情報と予め記憶部に記憶された列車在線情報とが整合する場合は前記一次元位置情報等の送信情報を作成し、整合しない場合は故障を示す送信情報を作成し、前記送信情報を通信部により送信する中央装置1と、緯度経度検出部により自身の現在位置を検出し、中央装置1から通信部により受信した一次元位置情報に基づき現在位置から列車までの距離を算出し、所定の距離になった場合に警報を出す携帯端末2とを備え、中央装置1は、列車在線情報が切り替わる境界部分に所定の領域を設け、当該領域では一次元位置情報と列車在線情報との整合判断の処理を行わない。【選択図】図1
