摘要

随着红外技术的发展，红外光通信已经成为越来越普及的无线通信方式。 在本次设计作品中，红外光通信装置采用红外光传输及无线工作机制，其组成结构主要包括：红外发射装置、中继转发节点、红外接收装置三部分组成。红外发射装置主要是由声音采集系统经单片机存储后发射，红外接收装置接收到的信息经单片机存储后再经过D/A转换播放。通过采用A/D，D/A转换的方法达到了本次作品设计的目的。

在电子消费领域当中，红外产品的使用较为普遍，它多用于简单的近距离控制，如家电、玩具、各种抄表系统、工业控制、娱乐设施等领域。所以，其具有很强的现实意义。

Abstract

With the development of infrared, and infrared optical communication has become more and more popular way of wireless communication.

This design works, infra-red communication devices use infrared light transmission and wireless working mechanisms, its composition include: infrared emitting device, relay node, an infrared receiver unit is composed of three parts. Infrared Launcher corresponds with sound collection system by single-chip computer memory after the launch, IR receiver receives the information via a single-chip storage, and then after d/a conversion play. Through the use of a/d,d/a conversion way to achieve the purpose of the production design.

In the field of consumer electronics, using infrared products are more prevalent, it is used for simple control at close range, such as household appliances, toys, metering systems, industrial control, recreational facilities, and other fields. So, it has a lot of practical significance.

Key words:Infrared Communication launch receiveA/D conversion D/A conversion
