Abstract
【解決手段】2T受信器4bの電圧検出部5は2T送信器3bからレール2に送信されて列車1の位置により変化するレール電流I22によるレール間電圧V21を受信して列車検知部7に送り、2T受信器4bの電流検出部6は3T送信器3cから軌道境界b1,b2に送信している3T用列車検知信号のレール電流I32を受信して列車検知部7に送る。2T受信器4bの列車検知部7は電圧検出部5から送られるレール間電圧V21と電流検出部6から送られるレール電流I32の変化を逐次検出し、レール間電圧V21があらかじめ定めた一定レベル以下になり、レール電流I32があらかじめ定めた一定レベル以上になったとき、列車1が軌道回路3Tから軌道回路2Tに進入したと判定する。
