amradio

AM 라디오 비상 방송 시스템 Red Pitaya FPGA를 사용하는 12채널 AM 라디오 방송 시스템으로, 무인 터널에서 비상 경보를 전송합니다. 터널에서 AM 라디오를 사용하는 이유? 건설 및 유지보수 중에 표준 AM 라디오를 장착한 차량은 이동 통신이 없는 터널을 통과합니다. AM 신호는 누설 동축 케이블을 통해 터널 구조를 따라 전파되며, 수신기는 저렴하고 견고하며 모든 차량에 이미 설치되어 있습니다. 이 시스템은 사전 녹음된 비상 경보를 여러 주파수로 방송하여 대역 내 어떤 방송국에 맞춰진 AM 라디오든 메시지를 수신...
