To provide a monitoring system for a railway vehicle capable of detecting an abnormality of a device supporting a vehicle body in a traveling railway vehicle at an early stage.SOLUTION: A monitoring system for a railway vehicle 1 includes a detection unit 2 and a determination unit 3. The detection unit detects a pressure A1 of a first air spring 21 disposed on the front right side, a pressure A2 of a second air spring 22 disposed on the front left side, a pressure A3 of a third air spring 23 disposed on the rear right side, and a pressure A4 of a fourth air spring 24 disposed on the rear left side in the traveling direction of a railway vehicle between a vehicle body 10 and a carriage with respect to the traveling railway vehicle. The determination unit determines an abnormality of the device supporting the vehicle body based on the pressure detected by the detection unit. The determination unit determines the abnormality based on a relationship between the magnitude of a diagonal imbalance P obtained by the following equation (1) or equation (2) and a traveling distance or an elapsed time of the railway vehicle. P=(A1-A2)-(A3-A4)...(1), P=(A3-A4)-(A1-A2)...(2)SELECTED DRAWING: Figure 1

    【課題】走行中の鉄道車両において車体を支持する装置の異常を早期に発見できる鉄道車両の監視システムを提供する。【解決手段】本開示は、検知部2と、判定部3と、を備える鉄道車両の監視システム1である。検知部は、走行中の鉄道車両に対し、車体10と台車との間で鉄道車両の進行方向における右前方に配置された第1空気ばね21の圧力A1、左前方に配置された第2空気ばね22の圧力A2、右後方に配置された第3空気ばね23の圧力A3、及び左後方に配置された第4空気ばね24の圧力A4を検知する。判定部は、検知部によって検知された圧力に基づき、車体を支持する装置の異常を判定する。判定部は、下記式(1)又は式(2)で求められる対角アンバランスPの大きさと、鉄道車両の走行距離又は経過時間との関係によって、異常を判定する。P=(A1−A2)−(A3−A4)・・・(1)、P=(A3−A4)−(A1−A2)・・・(2)【選択図】図1
