본 발명은 궤도 회로 안전 모니터링 장치에 관한 것으로서, 보다 상세하게는 열차의 차륜에 근접하여 측정된 초음파 신호를 증폭하는 신호 증폭기; 상기 증폭된 신호를 초음파 신호를 필터링하는 필터; 상기 필터링된 초음파 신호를 디지털로 변환하는 ADC; 상기 ADC를 통한 초음파 신호의 주기성을 검출하고, 차륜이 손상됐을 때 나타나는 특정 주기성이 발견될 경우 손상 경보를 표시하는 디스플레이 장치; 상기 모듈들을 제어하고 제1 논리부와 제2 논리부로 구성되는 제어부; 상기 제어부로부터 정보를 전달받아 논리합을 계산하는 통합 감시부; 상기 각 모듈의 초음파 신호를 저장하는 데이터베이스로 구성되는 궤도 회로 안전 모니터링 장치에 관한 것이다.

    The present invention relates to a track circuit safety monitoring device. More particularly, the present invention relates to a track circuit safety monitoring device which comprises: a signal amplifier for amplifying an ultrasonic signal measured in close proximity to train wheels; a filter for filtering the amplified signal into an ultrasonic signal; an analog-to-digital converter (ADC) for digitally converting the filtered ultrasonic signal; a display device for detecting the periodicity of the ultrasonic signal through the ADC and displaying a damage warning when a specific periodicity is found when the wheel is damaged; a control unit controlling modules and comprising a first logic unit and a second logic unit; an integrated monitoring unit for receiving information from the control unit to calculate a logical sum; and a database for storing ultrasonic signals of each module.
