摘　　要：红外光语音通信是利用红外光作为载波的一种新型通信方式。红外光语音通信系统包括红外光发射模块和红外光接收模块,通信方式采用模拟通信,该系统采用两对850nm波长红外光发光、接收管作为收发器件,实现了语音信号的定向传输,传输过程中要无明显失真,传输距离可达到8m。系统另外设计了中继转发结点,通信方向垂直改变90度以后,依然可以实现清晰传输。就解决了红外光直线传播的缺点,在一些特殊场合可以通过该设计避开障碍物,实现两个站点之间的自由通信,同时也可以增加传输距离。Infrared voice communication is a new way by using the infrared light as its carrier. Infrared voice communication system comprises an infrared light sending module and an infrared light receiving module. The communication mode is analog communication. The system adopts two infrared light sending tubes and two infrared light receiving tubes. Their wavelength is 850 nm. It realizes directional transmission of voice signals and there is no obvious distortion in the transmission. The distance of transmission can reach 8m. In addition, the system designed relay node. It can achieve a clear transmission when 90 degree change of the direction of communication. It solves the disadvantages of infrared light Linear Transmission. In some special occasions the design can dodge obstacles which helps to realize free communication between the two sites. At the same time, it also can increase the transmission distance.
