To propose a new technology for detecting the position and speed of a train on the ground side.SOLUTION: A train detection device 100 includes a measurement terminal 200 and a determination device 300, and detects a position and speed of a train located in a control section of an AC track circuit to which an AC signal is transmitted. The determination device 300 determines a train position in the control section based on a transmit signal state that is at least one of a transmit voltage, a transmit current, and a phase difference of the transmit current with respect to the transmit voltage, and a signal state change pattern which indicates the change in the transmit signal state from when the train enters the control section until the train reaches a transmit point. The train speed is calculated using the train position determined at the prescribed time interval and the prescribed time interval.SELECTED DRAWING: Figure 1

    【課題】地上側で列車の位置や速度を検知する新たな技術を提案すること。【解決手段】列車検知装置100は、計測端末200と判定装置300とを有し、交流信号が送信される交流軌道回路の制御区間に在線している列車の位置および速度を検知する。判定装置300は、送信電圧、送信電流および送信電圧に対する送信電流の位相差のうちの少なくとも1つである送信信号状態と、制御区間に列車が進入してから送信点に列車が到達するまでの送信信号状態の変化を示す信号状態変化パターンとに基づいて、制御区間における列車位置を判定する。そして、所定時間間隔で判定した列車位置と所定時間間隔とを用いて列車速度を算出する。【選択図】図1
