To provide a technique capable of always calculating a railroad crossing warning time for each train.SOLUTION: A railroad crossing warning time calculation device receives signal change information showing the change in an operating state of each relay from a field terminal, stores a drop time in a predetermined order in a storage area as a warning start time relating to a next train for each dropping of a relay in a start point which indicates that a train approaches to the start point, and calculates a period of time from the warning start time for one train read out from the storage area according to the predetermined order to the drop time as the railroad crossing warning time with respect to the one train every time a train approaches to an end point.SELECTED DRAWING: Figure 4
【課題】常時、且つ、列車毎に踏切警報時分を算出できるようにする技術を提供すること。【解決手段】踏切警報時分算出装置は、現場端末から各リレーの動作状態の変化を示す信号変化情報を受信し、始動点への列車進入を示す始動点リレーの落下毎に、当該落下時刻を、新たな列車に係る警報開始時刻として記憶エリアに所定順で記憶し、終動点への列車進入毎に、記憶エリアから所定順に従って読み出した一列車分の警報開始時刻から当該落下時刻までの時間を、当該一列車に対する踏切警報時分として算出する。【選択図】図4
