PROBLEM TO BE SOLVED: To provide an on-train train control device capable of reliably receiving a proper speed control signal while avoiding an influence of noise.SOLUTION: An on-train train control device for receiving a speed control signal transmitted from a ground device and performing speed control of a train includes: a Fourier transformation part for subjecting the received signal to Fourier transformation; and a signal determination part for determining that the received signal is not appropriate for spend control of the train when a signal level of a boundary frequency in a signal frequency range is higher than a signal level of a center frequency in a signal frequency range contained in a Fourier transformation signal generated at the Fourier transformation part, and a signal level higher than the signal level of the boundary frequency is present in a predetermined frequency range out of the signal frequency range from the boundary frequency.

    【課題】雑音の影響を回避しつつ、本来の速度制御信号を確実に受信可能な列車制御車上装置を提供する。【解決手段】地上装置から送信された速度制御信号を受信して、列車の速度制御を行う列車制御車上装置は、受信信号をフーリエ変換するフーリエ変換部と、フーリエ変換部で生成されたフーリエ変換信号に含まれる信号周波数範囲内の中心周波数の信号レベルよりも、信号周波数範囲の境界周波数の信号レベルの方が高く、かつ境界周波数から信号周波数範囲外の所定の周波数範囲内に、境界周波数の信号レベルよりも高い信号レベルが存在する場合には、受信信号を列車の速度制御に不適切と判断する信号判断部と、を備える。【選択図】図1
