To easily determine the state of a relay valve or regular solenoid valve of a railway vehicle.SOLUTION: A determination unit of a state determination device determines the state of a regular solenoid valve on the basis of a response time h1 of a command pressure to an opening/closing command signal and a change rate α1 of a command pressure AS that changes in response to the change of the opening/closing command signal (steps S110, S120, S130, S210). Also, the determination unit determines the state of a relay valve on the basis of a response time h2 of an output pressure BS to the command pressure AS, a change rate α2 of the output pressure BS that changes in response to the change of the command pressure AS and a difference between the command pressure AS and the output pressure BS (steps S140, S150, S160, S170, S220, S230).SELECTED DRAWING: Figure 3
【課題】鉄道車両の中継弁又は常用電磁弁の状態を簡便に判定する。【解決手段】状態判定装置の判定部は、開閉指令信号に対する指令圧力の応答時間h1及び開閉指令信号の変化に応じて変化する指令圧力ASの変化率α1に基づいて常用電磁弁の状態を判定する(ステップS110,S120,S130,S210)。また、判定部は、指令圧力ASに対する出力圧力BSの応答時間h2、指令圧力ASの変化に応じて変化する出力圧力BSの変化率α2、及び指令圧力ASと出力圧力BSの差に基づいて、中継弁の状態を判定する(ステップS140,S150,S160,S170,S220,S230)。【選択図】図3
