The present invention relates to an axle counter system. The system includes: a wheel detecting sensor which adheres to a rail to detect a wheel of a railroad car; and a sensor control unit which determines whether the railroad car enters and, at the same time, whether the wheel detecting sensor is detached from the rail based on a detection signal detected by the wheel detecting sensor. The wheel detecting sensor comprises a resonance magnetic sensor. The sensor control unit includes: an oscillator circuit which oscillates a resonant frequency to the wheel detecting sensor; a sensor driving circuit which drives the wheel detecting sensor by using the frequency oscillated by the oscillator circuit; a wheel detecting circuit which detects whether the railroad car enters by using the detection signal received from the wheel detecting sensor; a detecting sensor installation defect sensing circuit which controls a train detection signal so that the train detection signal is not generated when the wheel detecting sensor is displaced from a normal installation position; and an amplification circuit which amplifies a signal of the wheel detecting circuit and the detecting sensor installation defect sensing circuit.

    본 발명은 차축카운터시스템에 관한 것으로서, 레일에 부착되어 철도차량의 차륜을 검지하는 차륜검지센서와; 상기 차륜검지센서에서 검지된 검지신호를 기초로 철도차량의 진입여부와 함께 상기 차륜검지센서가 레일로부터 탈락되었는지를 판단하는 센서제어부를 포함하며, 상기 차륜검지센서는 공진형 자기 센서로 구비되고, 상기 센서제어부는, 상기 차륜검지센서로 공진 주파수를 발진하는 발진회로와; 상기 발진회로로부터 발진된 주파수를 이용하여 상기 차륜검지센서를 구동하는 센서구동회로와; 상기 차륜검지센서로부터 수신된 검지신호를 이용해 철도차량의 진입여부를 검지하는 차륜검지회로와; 상기 차륜검지센서가 정상적인 설치위치로부터 벗어나는 경우 열차검지신호가 발생되지 않도록 제어하는 검지센서설치불량검출회로와; 상기 차륜검지회로와 상기 검지센서설치불량검출회로의 신호를 증폭하는 증폭회로를 포함하는 것을 특징으로 한다.
