PROBLEM TO BE SOLVED: To provide a monitoring system for a railway vehicle distribution board which can quickly estimate a troubled portion even when an operation abnormality of an electric facility of the railway vehicle is caused by a failure of a relay installed on the distribution board.SOLUTION: A monitoring system comprises: a signal detection unit (101) which detects electric signals of a plurality of terminals in a connector (12) arranged on a distribution board (10); a simulation circuit unit (104) which simulates operation of a relay circuit according to the electric signals detected by the signal detection unit; a history storage unit (105) which stores a history of simulation operations by the simulation circuit unit; a determination unit (102a) which determines whether each electric signal of the terminals detected by the signal detection unit conforms to each signal of the terminals in the simulation circuit unit corresponding to the terminals; and a failure estimation unit (102b) which estimates, when unconformity is determined by the determination unit, a troubled portion of the relay circuit on the basis of the electric signal of the terminal determined as unconformity and the operation history of the simulation circuit unit.SELECTED DRAWING: Figure 2

    【課題】配電盤に設けられた継電器が故障して、鉄道車両の電気設備の動作に異常が生じた場合でも、速やかに故障箇所を推定できる鉄道車両用配電盤の監視装置を提供することを目的としている。【解決手段】この監視装置は、配電盤(10)に設けられたコネクタ(12)の複数の端子の電気信号を検知する信号検知部(101)と、信号検知部が検知した電気信号に応じて継電器回路の動作を模擬する模擬回路部(104)と、模擬回路部の模擬的な動作の履歴を記憶する履歴記憶部(105)と、信号検知部が検知した複数の端子の各電気信号と複数の端子に対応する模擬回路部の複数の端子の各信号とが合致するか判定する判定部(102a)と、判定部により不一致と判定された場合に、不一致と判定された端子の電気信号と、模擬回路部の動作の履歴に基づいて、継電器回路の故障箇所を推定する故障推定部(102b)とを備えている。【選択図】図2
