무선전화기 휴대장치의 저전압 검출방법 및 그 시스템Low voltage detection method and system for radiotelephone portable device

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명 무선전화기 휴대장치의 저전압 검출시스템 구성도, 제3도는 제2도의 각부 입출력 파형도.2 is a configuration diagram of a low voltage detection system of a portable telephone apparatus of the present invention, and FIG. 3 is an input / output waveform diagram of each part of FIG.

Claims (2)

밧데리(1)의 저전압을 검출하여 디스플레이부(4)에 표시하는 무선전화기의 저전압 검출시스템에 있어서, 상기 밧데리(1)의 전압을 분압하여 그 레벨을 검출하는 전압검출부(2)와, 상기 전압검출부(2)로부터 검출된 전압 및 기준전압(Vref)의 레벨을 비교하여 그에따른 제어전압을 출력하는 비교부(3)와, 상기 비교부(3)의 전압 레벨에 따라 스위칭되어 밧데리(1)의 전압상태를 표시하는 디스플레이부(4)와, 상기 비교부(3)의 전압레벨에 따라 휴대장치의 전체시스템을 제어하는 마이컴(6)과, 상기 마이컴(6)의 제어전압에 의해 스위칭되어 전압검출부(2)의 입력전압을 제어하는 전압제어부(5)와, 통화중 상기 마이컴(6)이 제어전압에 의해 구동하여 밧테리(1)의 저전압 상태를 경보하여 주는 스피커(7)로서 구성함을 특징으로한 무선전화기 휴대장치의 저전압 검출시스템.In the low voltage detection system of the radiotelephone which detects the low voltage of the battery 1 and displays it on the display unit 4, the voltage detection unit 2 for dividing the voltage of the battery 1 and detecting the level thereof, and the voltage The comparator 3 which compares the level of the voltage detected from the detector 2 and the level of the reference voltage Vref and outputs a control voltage according thereto, and is switched according to the voltage level of the comparator 3 and the battery 1 The display unit 4 for displaying the voltage state of the microcomputer 6, the microcomputer 6 for controlling the entire system of the portable device according to the voltage level of the comparison unit 3, and the control voltage of the microcomputer 6 As a voltage controller 5 for controlling the input voltage of the voltage detector 2 and a speaker 7 which is driven by the control voltage during the call and alerts the low voltage state of the battery 1 during the call. Low voltage detection of a portable telephone device characterized in that Stem. 초기에 마이컴(6)은 휴대장치의 상태를 체크하여 휴대장치가 대기상태이고 밧데리의 전압이 저전압이면 디스플레이부(4)를 구동시켜 표시하고, 상기에서 휴대장치가 통화상태이고 밧데리의 전압이 저전압이면 디스플레이부(4)를 구동시킴과 아울러 일정시간(t3)동안 경보음을 송출하고, 이후 일정시간(t3)이 경과되면 자동통화를 차단하는 것을 특징으로 하는 무선전화기 휴대장치의 저전압 검출방법.Initially, the microcomputer 6 checks the state of the portable device. If the portable device is in the standby state and the battery voltage is low, the microcomputer 6 drives the display unit 4 to display the mobile device. The mobile device is in a call state and the voltage of the battery is low. And driving the display unit (4) and transmitting an alarm sound for a predetermined time (t3), and then interrupting the automatic call when a predetermined time (t3) has elapsed. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
