To provide a train approach alarming system having high safety when performing work of maintenance or the like in a rail track in a multiple-line zone.SOLUTION: A portable terminal held by a trackman comprises a radio receiver which can receive a radio signal, and an alarm terminal which receives data transmitted from the radio receiver and can generate an alarm. The radio receiver includes reception means which can receive a radio signal, and communication means which can transmit and receive data to/from the alarm terminal. The alarm terminal includes communication means which can receive data transmitted from the radio receiver, GPS reception means which can receive a GPS radio wave, terminal position recognition means for recognizing an own position on the basis of the received GPS information, and train approach determination means for extracting radio operation information about a rail track near the position of the alarm terminal on the basis of train operation information received from the radio receiver and determining the existence/nonexistence of a train approaching into a prescribed distance on the basis of the information, and the alarm terminal can generate an alarm on the basis of a determination result by the train approach determination means.SELECTED DRAWING: Figure 1
【課題】多線区エリアにおいて線路内での保守等の作業を行う際の安全性の高い列車接近警報システムを提供する。【解決手段】作業員が保有する携帯端末を、無線信号を受信可能な無線受信機と無線受信機から送信されたデータを受信し警報を発生可能な警報端末とで構成し、無線受信機には無線信号を受信可能な受信手段および警報端末とデータの送受信が可能な通信手段を設け、警報端末には無線受信機から送信されたデータを受信可能な通信手段およびGPS電波を受信可能なGPS受信手段と、受信したGPS情報に基づいて自己の位置を認識する端末位置認識手段と、無線受信機から受信した列車運行情報に基づいて当該警報端末の位置近傍の線路に関する列車運行情報を抽出し該情報に基づいて所定の距離内に接近している列車の有無を判定する列車接近判定手段とを設け、列車接近判定手段による判定結果に基づいて警報を発生可能に構成した。【選択図】図1
