MAINTENANCE DEVICE, MAINTENANCE SYSTEM AND MAINTENANCE METHOD
To detect abnormalities of a rail and an electric apparatus connected to the rail.SOLUTION: A maintenance device 10 sends a pulse signal from a prescribed observation point P of a rail R, observes an observation signal appearing at the observation point P after sending the pulse signal, compares an observation signal received this time with an observation history of the observation signal, and detects an occurrence of an abnormality at either of the rail R or an electric apparatus 20 connected to the rail R.SELECTED DRAWING: Figure 1
【課題】レール及びレールに接続された電気機器の異常を検出すること。【解決手段】保全装置１０は、レールＲの所定の観測点Ｐからパルス信号を送信し、パルス信号の送信後に観測点Ｐに現れる観測信号を観測し、観測信号の観測履歴と、今回受信した観測信号とを比較して、レールＲ及びレールＲに接続されている電気機器２０の何れかに異常が発生したことを検出する。【選択図】図１
