3. 발명의 해결방법의 요지3. Summary of Solution to Invention
상용교류를 직류전압으로 변환하는 AC/DC 컨버터(10) 및 직류 24V/48V 겸용하는 DC/DC 컨버터(11)와 상기 직류전압을 발생제어하는 파워컨트롤(12) 및 (13)으로 연결구성되어 있는 전원부(1)와, 본 장치의 동작에 필요한 수 MHz의 신호를 발생시키는 OCXO(14) 및 (15)과 상기한 파워컨트롤(12) 또는 (13) 및 상기한 OCXO(14) 및 (15)의 전압 및 전류를 검출하여 다른 정상적인 부분으로 절체시키는 체인지컨트롤(16)과로 연결구성되어 있는 전원이중화부(2)와, 기준신호를 공급할 수 있도록 증폭 분할 및 파형정형이 행해지는 스프릿터(17~20) 및 기준신호를 스프릿터(17~20)로 전해주는 스위치(21)과로 연결구성되어 있는 전압 및 파형변환부(3)와를 구비하는 것을 특징으로 하는 무선호출기용 기준신호발생 공급장치이다.AC / DC converter 10 for converting commercial AC to DC voltage and DC / DC converter 11 for both DC 24V / 48V and power control 12 and 13 for generating and controlling the DC voltage. Power supply unit 1, OCXOs 14 and 15 for generating signals of several MHz necessary for the operation of the apparatus, power control 12 or 13 described above, and OCXOs 14 and 15 described above. Power supply redundancy unit 2, which is connected to a change control unit 16 for detecting the voltage and current of the power supply unit and switching to another normal part, and a splitter 17 in which amplification division and waveform shaping are performed to supply a reference signal. And a voltage and waveform converting unit (3) configured to be connected to the switch (21) for transmitting the reference signal to the splitters (17 to 20) and the reference signal generating supply device for the wireless pager. .
4. 발명의 중요한 용도4. Important uses of the invention
기준신호발생장치의 생명이라고 볼 수 있고 기본파주변잡음을 줄이기 위하여 선형성직류전원공급장치를 채용하여 불필요한 잡음을 최소화하였다. 또 상용교류 및 무정전전원의 직류전압을 동시에 사용할 수 있으므로 사용전압의 폭을 극대화하여 실용성을 높였다. 그리고 내부의 상태를 외부에서 가시할 수 있도록 하여 사용자가 쉽게 본 장치의 이상유무를 판단할 수 있다.It can be regarded as the life of the reference signal generator, and the linear DC power supply is adopted to reduce the fundamental wave noise to minimize unnecessary noise. In addition, since the DC voltage of the commercial AC and the uninterruptible power supply can be used at the same time, the utility voltage is enhanced by maximizing the width of the voltage used. And the internal state can be seen from the outside, the user can easily determine whether there is an abnormality of the device.
