PROBLEM TO BE SOLVED: To provide a technique for an axle detection with a simple configuration.SOLUTION: In an axle sensor 10, a first reception coil RXa is so located as to face a first transmission coil TXa with a rail interposed therebetween and to perform mutual induction. A second reception coil RXb is so located as to face a second transmission coil TXb with a rail interposed therebetween and to perform mutual induction. In an output of a reception coil part RX, an output waveform difference is generated in the cases that only the first reception coil RXa, only the second reception coil RXb, and both of the first reception coil RXa and the second reception coil RXb respectively detect an axle. An axle detection function can be realized by one detection circuit by calculating the output waveform difference and a time when both of the first reception coil RXa and the second reception coil RXb detect the axle.SELECTED DRAWING: Figure 6

    【課題】簡易的な構成による車軸検知技術を提供する。【解決手段】車軸センサ10において、第1の受信コイルRXaは、レールを挟んで第1の送信コイルTXaと対向して配置されて相互誘導する。第2の受信コイルRXbは、レールを挟んで第2の送信コイルTXbと対向して配置されて相互誘導する。受信コイル部RXの出力では、第1の受信コイルRXaのみ、第2の受信コイルRXbのみ、第1の受信コイルRXaと第2の受信コイルRXbの両方が、それぞれ車軸を検知した場合の出力波形レベル差が発生する。出力波形のレベル差と、第1の受信コイルRXaと第2の受信コイルRXbの両方が車軸を検知した時間を算出することによって、車軸検出機能を1つの検知回路で実現することができる。【選択図】図6
