Abstract

본 발명은 음성 통화와 변조된 디지탈 데이타 전송을 전환하므로써 일반 상용 무전기를 이용하여서 음성 통화와 변조된 디지탈 데이타를 송수신할 수 있도록 한 무전기의 음성 데이타와 변조된 디지탈 데이타를 스위칭하는 장치 및 방법에 관한 것으로, 무전기 송수화기의 PTT 스위치를 누르고 놓고 하는 기계적인 조작 대신 상기 PTT 단자에 컨트롤 신호를 임의로 입력해서 계전기를 이용하여 음성신호나 가청 주파수 대역으로 변조된 디지탈 신호 중 하나를 선택하고 그 선택된 신호를 송신할 건지 수신할 건지 컨트롤 신호로 스위칭하도록 스위칭 회로를 설치한 것이다.The present invention relates to an apparatus and a method for switching voice data of a transceiver and a modulated digital data so that a voice communication and a modulated digital data can be transmitted and received by switching a voice call and a modulated digital data transmission by using a general commercial radio Instead of mechanically pressing and releasing the PTT switch of the radio handset, a control signal is arbitrarily input to the PTT terminal and a relay is used to select one of a digital signal modulated with a voice signal or an audible frequency band and transmit the selected signal A switching circuit is provided to switch to a control signal whether to receive or not to receive.
