广场LED大屏音频信号远距离无线传输系统的设计与制作

Design and Production of Long-distance Wireless Transmission System of Square LED Large Screen Audio Signals

目前LED大屏信号分为网线传输的有线信号和GPRS、3G、4G等无线方式传播的无线信号。采用BH1417F调频立体声发射集成芯片制作发射机,数字FM调频机作为接收机,通过GP天线实现音频信号的传输。

Current LED large screen signals include cable signals transmitted through cable,and wireless signals transmitted wirelessly,such as GPRS,3 G,4 G. This design uses the BH1417 F FM stereo transmitter integrated chip as the transmitter,applies digital FM FM headphones as the receiver,and achieves the transmission of audio signals through GP antenna.
