PROBLEM TO BE SOLVED: To provide a railway vehicle with electric source installed trucks in which vehicle, compatibly, the longevity or capacity reducing of the source is accomplished by means of the reduction of electric power consumption and enough amounts of state information expressing disorders or abnormality signs are secured.SOLUTION: A state monitor device for a railway vehicle comprises monitoring sensors to detect state information of equipment in trucks and a wireless transmitter to radio-transmit signals containing the state information detected by the monitoring sensors at intervals of a certain period and when the monitored value dependent on the state information is decided to be equal to or below a threshold value, then the transmitter radio-transmits the signals at intervals of an initially specified period and when the monitored value is decided to exceed the threshold value, then the transmitter radio-transmits the signal at intervals of a shorter period than the initially specified.SELECTED DRAWING: Figure 1

    【課題】電源が台車に設けられた鉄道車両において、消費電力の低減による電源の長寿命化あるいは小容量化と、異常又は異常予兆を示す状態情報の十分な情報量の確保とを両立させる。【解決手段】鉄道車両の状態監視装置は、台車の機器の状態情報を検出する監視センサと、前記監視センサで検出された状態情報を含む信号を送信間隔をあけて無線送信する無線送信器と、を備え、前記無線送信器は、前記状態情報を用いた監視値が閾値以下であると判定された場合に、前記送信間隔を所定の初期間隔として前記信号を無線送信し、前記監視値が前記閾値を超えたと判定された場合に、前記送信間隔を前記初期間隔よりも小さい狭間隔として前記信号を無線送信する。【選択図】図1
