Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
전화기cellphone
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
전화기의 통화중 상태에서 대기상태로 전환하는 기술Technology for switching from the busy state of the phone to the standby state
3. 발명의 해결 방법의 요지3. Summary of the Solution of the Invention
통화신호 및 통화대기신호를 발생하는 스위치와, 통화음성신호를 통화전압으로 변환하는 수단과, 통화유무를 판단하기 위한 기준전압을 구비하며 통화전압과 기준전압을 비교하여 통화중 또는 비통화중 상태임을 나타내는 통화판단신호를 발생하는 수단과, 대기상태로 전환하기 위한 기준시간 값을 저장하는 수단과, 스위치로부터 통화신호 수신시 통화판단신호를 수신하며 비통화중상태의 통화판단신호 수신시 발생 시간을 카운트하고 카운트 시간이 기준시간을 초과할 시 통화루프를 단절하여 통화대기 상태로 천이시키는 제어수단으로 구성됨.It has a switch for generating a call signal and a call waiting signal, a means for converting a call voice signal into a call voltage, and a reference voltage for determining whether there is a call, and comparing the call voltage and the reference voltage to a busy or non-call state. Means for generating a call judgment signal indicating that the call is received, means for storing a reference time value for switching to the standby state, time for receiving a call judgment signal upon receiving a call signal from a switch and receiving a call judgment signal for a non-call state. It is composed of a control means for counting the number and the transition to the call standby state by disconnecting the call loop when the count time exceeds the reference time.
4. 발명의 중요한 용도4. Important uses of the invention
전화기에서 원치않는 통화중상태인 경우 강제적으로 대기상태로 전환시켜 착신효율 및 전원을 절약함.When the phone is in an unwanted call state, it is forced to go to the standby state, saving call efficiency and power.
