1、 1 红外红外遥控遥控发射和接收系统发射和接收系统设计设计 摘要 本设计是以红外技术为基础,可以实现无线遥控,摆脱了信息传递需要导线的限制,而且红外 实现方式灵活,得到了广泛的应用。特别是随着芯片技术的发展,红外集成芯片价格的降低, 更加扩展了红外的应用范围。 现在在我们的日常生活中都能感受到红外的应用， 以及它给我 们带来的便利。 本设计充分利用能够很容易买到的普通电视机遥控器， 通过编码发射红外线， 然后由通用红外接收芯片 sw0038 实现对红外的接收，但是因为考虑到题目的要求仅仅是实 现对一个开关的简单开管控制， 所以舍弃了依靠单片机来对遥控器发出的红外进行解码实现 多种控制的方案。本

2、方案简洁可行，充分利用现有的资源进行开发，取得比较好的效果，并 且具有良好的移植性，可以通过简单的修改就应用到其他领域。 关键字：红外遥控 红外解码 双稳态 Abstract This design is take the infrared technology as a foundation, realizing the wireless remote control, getting rid of the the limit of wire information transmission. Beacause infrared technology is easy to be realiz

3、ed,it is widely used in many fields. Specially ,with the chip technology development, infrared integrated chip price reducing, even more expanded the infrared application scope . Now in our daily life ,we can feel the application of the infrared, and the convenience it has brought us.In this design,

4、I take ordinary television remote control device to realize coding and Infrared Emission,then it is received by the general infrared receive chip sw0038 .what the topic requests is merely the realization of a simple switch control,so I give up the program on the MCU. The program is simple and feasible, making full use of the existing resources for development, and achieve fairly good results.It has a good portability,so only after a little change,it can be transplanted to other fields.
