Abstract
본 발명은 정정시에 여유전원인 예비베터리전원의 백업받아 본체에 인가하여, 정전시에도 본체가 동작하는 무선전화기에 관한 것으로, 본 발명은 상용교류전원을 직류변환하는 직류전원장치로부터 직류전원을 인가받는 본체와 베터리를 구비하여 상기 본체와 무성통신하는 휴대기와, 상기 휴대기의 베터리의 여유분인 예비용베터리로 이루어지는 무선전화기에 있어서, 상기 본체가 상기 직류전원장치로부터 전압폭이 불안정한 직류전원을 입력받아 음성신호를 무선신호로 변환하여 송신하고, 수신된 무선신호를 으성신호를 변환하는 무선송수신부와, 상기 정전압전원부로부터 인가되는 직류전원에 인가받아 상기 무선송수신부의 제어동작을 하는 마이콤과, 상기 직류전원장치로부터 입력되는 직류전원으로 출력단에 접속되는 상기 예비배터리를 충전시키는 예비배터리충전부와, 상기 직류전원장치로부터 입력되는 직류전원으로 출력단에 접속되는 상기 휴대기의 배터리를 충전시키는 휴대기 충전부와, 상기 예비 배터리충전부와의 출력측과 상기 정전압전원부의 입력측사이에 구비되어 예비배터리의 전원을 정전압전원부로 인가하는 전원백업부를 구비한다.The present invention relates to a radiotelephone which receives a backup of a spare battery power, which is a spare power supply at the time of correction, and applies it to the main body, and operates the main body even during a power failure. A radiotelephone having a main body and a battery, the portable telephone having a silent communication with the main body, and a spare battery which is a spare part of the battery of the portable device, wherein the main body inputs a DC power source having an unstable voltage width from the DC power supply device. A wireless transmitter / receiver for converting a voice signal into a wireless signal and transmitting the received wireless signal, and converting a received signal into a wireless signal; and a microcomputer for controlling the wireless transmitter / receiver by receiving DC power applied from the constant voltage power supply unit; The spare battery connected to the output terminal with a DC power input from the DC power supply unit It is provided between a spare battery charging unit for charging, a portable charging unit for charging a battery of the portable device connected to an output terminal with a DC power input from the DC power supply device, an output side of the spare battery charging unit, and an input side of the constant voltage power supply unit. And a power backup unit for supplying power of the spare battery to the constant voltage power supply unit.
