시간예약 자동 다이얼링방법Time reservation automatic dialing method

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

제1도는 본 발명을 수행하기 위한 전화기의 회로도, 제2도는 본 발명에 따른 흐름도.1 is a circuit diagram of a telephone for carrying out the invention, and FIG. 2 is a flow chart according to the invention.

Claims (1)

시간예약 자동 다이얼링 방법에 있어서, 링신호를 검출하는 링거회로(10)와, 다이얼 디지트 스피커폰 기능신호등을 키의 누름에 의해 입력시키는 키입력회로(20)와, 내장된 프로그램에 의하여 키입력회로(20)의 입력신호를 분석판단하여 시스템 동작수행의 제어신호를 출력하는 마이크로프로세서(30)와, 국선을 온·오프 후크하기 위한 후크스위치(HS-HS1)와, 상기 후크스위치(HS-HS1)에 각각 직병렬 접속되어 마이크로프로세서(30)에서 출력하는 스피커폰 기능 제어신호에 의해 국선을 온·오프 후크상태로 전환하는 아나로그스위치(ASW-ASW1)와, 상기 마이크로프로세서(30)의 펄스송출 제어신호에 의해 펄스신호를 발생하여 송출하는 다이얼펄스회로(40)와, 상기 마이크로프로세서(30)의 다중주파 부호 송출제어신호에의해 다중주파 부호를 발생하여 송출하는 동시에 핸드셋의 송수화기를 통해 국선전류에 음성신호를 중청 출력하는 통화회로(50)와, 상기 마이크로프로세서(30)의 스피커폰 기능제어신호에 의해 국선루프를 형성함과 동시에 국선전류에 음성신호를 중첩시키어 송수하는 스피커폰회로(60)을 구비하여, 상기 키입력회로(20)의 키입력신호가 시간예약 키라고 판단하였을시에 상기 마이크로프로세서(30)가 시간예약 모드로 세이브하는 제1단계와, 상기 키입력회로(20)에서 예약시간과 예약할 다이얼번호가 입력시 예약시간 데이터와 다이얼 디지트데이터를 마이크로프로세서(30)내의 내부카운터로 예약시간을 체크하는 제3단계와, 제3단계에서 예약시간이라고 판단하였을 때 마이크로프로세서(30)가 스피커폰 기능제어신호를 아나로그스위치(ASW-ASW1)와 스피커폰회로(60)로 출력하여 국선루프를 형성하며 소정 메모리영역에 기기록된 다이얼 디지트를 리이드하여 펄스/톤 다이얼송출 제어신호를 다이얼 펄스회로(40)/통화회로(50)로 출력하여 예약다이얼 디지트를 송출하는 제4단계로 함을 특징으로 한 시간예약 자동 다이얼링방법.A time reservation automatic dialing method, comprising: a ringer circuit 10 for detecting a ring signal, a key input circuit 20 for inputting a dial digit speakerphone function signal, etc. by pressing a key, and a key input circuit by a built-in program ( A microprocessor 30 which outputs a control signal for performing a system operation by analyzing the input signal of 20), a hook switch HS-HS 1 for turning on / off a trunk line, and the hook switch HS-HS 1 ) an analog switch (ASW-ASW 1 ) for switching a trunk line to an on / off hook state by a speakerphone function control signal output from the microprocessor 30 and connected in parallel and in parallel with each other; A dial pulse circuit 40 for generating and sending a pulse signal by a pulse sending control signal and a multi-frequency code for generating and sending a multi-frequency code by the multi-frequency code sending control signal of the microprocessor 30. At the same time, a voice circuit is outputted to the trunk line current through the handset of the handset, and a trunk line loop is formed by the speaker phone function control signal of the microprocessor 30, and the voice signal is superimposed on the trunk line current. A first step in which the microprocessor 30 saves in the time reservation mode when it is determined that the key input signal of the key input circuit 20 is the time reservation key; A third step of checking the reservation time of the reservation time data and the dial digit data with an internal counter in the microprocessor 30 when the reservation time and the dial number to be reserved are input by the key input circuit 20; and the reservation time in the third step. when it is determined that the microprocessor 30 is output to the speaker phone function control signal to the analog switch (ASW ASW-1) and the speaker circuit 60 to form a loop and CO And a fourth step of outputting the pulse dial tone transmission control signal to the dial pulse circuit 40 / call circuit 50 by reading the dial digits recorded in the predetermined memory area and sending out the reserved dial digits. Automatic time dialing. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
