스피커폰의 자동응답방법Auto Answering Method of Speakerphone

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

제1도는 본 발명에 따른 스피커폰 회로도, 제2도는 본 발명에 따른 흐름도.1 is a speakerphone circuit diagram according to the present invention, Figure 2 is a flow chart according to the present invention.

Claims (1)

스피커폰의 자동응답방법에 있어서, 국선전류를 스위칭하기 위한 후크스위치(HS-HS1)와, 소정의 제어신호에 의해 국선전류를 스위칭하는 아나로그스위치(ASW)와, 링거신호를 재생하여 출력하는 링거회로(10)와, 링거신호를 검출하여 소정의 신호로 출력하는 링 검출회로(20)와, 링검출신호를 소정의 스위칭 제어신호의 입력에 의해 출력하는 자동모드 스위치(30)와, 스피커폰의 기능 및 다이얼신호를 입력시키는 키입력회로(40)와, 내장 프로그램에 의해 입력되는 키신호를 분석하여 제어신호를 출력하는 마이크로프로세서(50)와, 마이크로프로세서(50)의 제어에 의해 다이얼펄스신호를 발생하는 다이얼펄스회로(60)와, 마이크로프로세서(50)의 제어에 의해 통화로를 형성하고 핸드셋의 송수화기로 통화를 이루는 통화로부(70)와, 마이크로프로세서(50)의 제어에 의해 인에이블되어 통화로를 형성하고 마이크와 스피커를 통해 음성신호를 송수하는 스피커폰회로(80)를 구비하여, 상기 키입력회로(40)의 입력신호가 자동응답모드 키일 때 자동응답 제어신호를 자동응답모드 스위치(30)로 출력하여 자동응답모드로 들어감과 동시에 링검출신호의 유무를 판단하는 제1단계와, 상기 제1단계의 판단에서 링신호가 검출하였다고 판단시에 링신호 입력신호 횟수를 카운팅하고 마이크로프로세서(50) 내부 메모리에 지정된 링수에 일치하는가를 비교판단하는 제2단계와, 제2단계에서 링신호수가 일치한다고 판단시 마이크로프로세서(50)가 스피커폰 기능제어신호를 아나로그스위치(ASW)와 스피커폰회로(80)로 출력하여 국선루프를 형성하고 통화상태로 하는 제3단계로 함을 특징으로 하는 스피커톤의 자동응답 방법.In the automatic response method of the speakerphone, a hook switch (HS-HS 1 ) for switching the trunk line current, an analog switch (ASW) for switching the trunk line current according to a predetermined control signal, and a ringer signal are reproduced and output. A ringer circuit 10, a ring detection circuit 20 for detecting a ringer signal and outputting the ringer signal as a predetermined signal, an automatic mode switch 30 for outputting the ring detection signal by inputting a predetermined switching control signal, and a speakerphone A key input circuit 40 for inputting a function and a dial signal, a microprocessor 50 for analyzing a key signal input by a built-in program and outputting a control signal, and a dial pulse under control of the microprocessor 50 A dial pulse circuit 60 for generating a signal, a call path unit 70 for forming a call path under the control of the microprocessor 50, and making a call with the handset of the handset, and for the control of the microprocessor 50. It is enabled by the speaker phone circuit 80 to form a communication path and to transmit a voice signal through the microphone and the speaker, when the input signal of the key input circuit 40 is the auto answer mode key to automatically generate an auto answer control signal The first step of outputting to the answer mode switch 30 to enter the auto answer mode and determining the presence or absence of a ring detection signal and the number of ring signal input signals when the ring signal is detected in the determination of the first step. In the second step of counting and comparing the number of rings specified in the microprocessor 50 internal memory, and when determining that the number of ring signals coincides in the second step, the microprocessor 50 converts the speakerphone function control signal into an analog switch ( ASW) and speakerphone circuit 80 to form a trunk line loop, and the third step of making a call state, the automatic response method of the speaker tone. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
