RAIL BREAKAGE DETECTION DEVICE AND RAIL BREAKAGE DETECTION METHOD
To provide a rail breakage detection device capable of detecting rail breakage from a vehicle side.SOLUTION: A rail breakage detection device detects rail breakage from a vehicle side. The rail breakage detection device includes an acceleration sensor 3 mounted on a vehicle 1, a data recorder 4 for recording acceleration data measured by the acceleration sensor, a high frequency determination unit for performing first determination according to a result obtained by applying high frequency band-pass filter processing to the acceleration data, a low frequency determination unit for performing second determination according to a result obtained by applying low frequency band-pass filter processing to the acceleration data, and a breakage determination unit for determining the presence of a rail breakage portion 21 based on the first and second determination results.SELECTED DRAWING: Figure 1
【課題】レール破断を車両側から検知させることが可能なレール破断の検知装置を提供する。【解決手段】レール破断を車両側から検知させるレール破断の検知装置である。そして、車両１に取り付けられる加速度センサ３と、加速度センサによって測定された加速度データを記録するデータレコーダ４と、加速度データに高周波バンドパスフィルタ処理を施した結果から第１の判定を行う高周波判定部と、加速度データに低周波バンドパスフィルタ処理を施した結果から第２の判定を行う低周波判定部と、これらの第１及び第２の判定結果に基づいてレール破断箇所２１の有無を判定する破断判定部とを備えている。【選択図】図１
