To use the power obtained from vibration of a rail for determining abnormalities in the rail more efficiently compared to the case where no conditions are set for measurement execution.SOLUTION: A determination unit 111 refers to condition information 121 stored in a memory 12 and receives a signal from a clock 16 or a sensor 15 to determine whether or not the conditions described in the condition information 121 are satisfied. If the determination unit 111 determines that the predetermined conditions described in the condition information 121 are satisfied, it notifies a switching unit 112 to that effect. When the determination unit 111 determines that the above conditions are satisfied, the switching unit 112 switches a mode of a rechargeable battery 14. When the mode of the rechargeable battery 14 is switched, a measurement unit 113 measures vibration data indicating vibration of a rail R sensed by a sensor 15, and stores the measurement result in a vibration data table 122 of the memory 12.SELECTED DRAWING: Figure 6

    【課題】計測の実行に条件を設けない場合に比べて、レールの振動により得られた電力をそのレールの異常判定に効率的に利用する。【解決手段】判定部111は、メモリ12に記憶された条件情報121を参照するとともに、クロック16、又はセンサ15からの信号を受信して、この条件情報121に記述された条件を満たしているか否かを判定する。そして、条件情報121に記述された所定の条件を満たしていると判定すると、判定部111は、その旨を切替部112に伝える。切替部112は、判定部111が、上記の条件を満たしていると判定したことを伝えた場合に、充電池14のモードを切替える。充電池14のモードが切替えられると、計測部113は、センサ15が感知した、レールRの振動を示す振動データを計測して、その計測結果をメモリ12の振動データ表122に記憶する。【選択図】図6
