Abstract

충격감지시스템은 무게질량이 그 내부에 코일을 구비하며, 질량외부로 돌출하여 이 코일의 상단에 이동루프가 형성되어 강자성체코어의 외부에서 이동되면서 변화되는 인덕턴스를 발생시키고, 이 인덕턴스변화부에 따른 발진 및 진폭주파수를 엔벨로프 검파하고, 이렇게 전파된 신호에서 직류성분을 제거하여 증폭한 다음 저레벨 및 고레벨 저역필터에 동시에 인가하며, 이들 저역필터로부터의 신호에 대하여 소정의 시정수를 갖는 반파정류된 타이밍펄스를 발생시키도록 하므로 경고장치가 작동되게 한다.The shock sensing system has a coil with a weight mass inside it, and protrudes out of the mass to form a moving loop at the top of the coil to generate an inductance that is changed while moving outside of the ferromagnetic core. Envelope detection of the oscillation and amplitude frequencies, the DC component removed from the propagated signal, amplified and applied simultaneously to the low and high level low pass filters, and half-wave rectified timing with a predetermined time constant for the signals from these low pass filters. It generates a pulse so that the warning device is activated.
