| Abstract: | 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. |
