基于红外光的语音传输及中继系统设计

Based on the infrared voice transmission and relay system design

设计的红外通信及中继装置是以红外光为传输媒质,运用数字锁相环集成电路,实现红外语音的直接通信和经过多个中继节点的间接远距离通信。该装置由红外发射、接收以及中继部分组成,能够实现远距离的多方向、多节点语音传输,并且具有较高的传输速度、干扰小、系统稳定可靠、成本低廉、制作简单和传输距离可根据需要、利用多个中继节点延长的特点,在实际中有着很好的应用前景。

In this paper, the design of infrared communication and relay device based on infrared transmission medium, the use of digital phase locked loop integrated circuit, realizes the infrared voice direct communication and indirect long distance communication through multiple relay nodes. The de- vice consists of infrared emission and receiving and relay parts, multiple direction, can realize remote node voice transmission. And has high transmission speed, low interference, the system is stable, reli- able, low cost, simple to the characteristics of the transmission distance can be extended, in practice, has a good application prospect.
