红外线遥控在现阶段有着很广阔的应用。家电、玩具等都有红外线的身影。它有着体积小、低功耗、低成本、环保等特点，使得它在不断的发展推广。甚至在一些恶劣的环境下也会用到它。本设计是基于单片机和红外线信号设计的遥控风扇系统，通过单片机对红外线编码和解码实现对电机状态的控制。该设计实现了风扇控制的几个基本功能：开/关功能、三档调速功能、10分钟到4小时不同时间段的定时功能。经过软硬件的实现以及模块和系统调试，上述功能都已实现。这个设计结构简单、成本低廉、使用方便，具有家电方面的应用意义。(Infrared remote control has a wide range of applications at this stage. Home appliances, toys and so on have infrared images. It has the characteristics of small size, low power consumption, low cost and environmental protection, which makes it continuously develop and promote. It can be used even in harsh environments. This design is based on the single-chip computer and infrared signal design of remote control fan system, through the single-chip computer to infrared coding and decoding to achieve the control of motor status. The design realizes several basic functions of fan control: on/off function, three-speed regulation function, timing function in different time periods from 10 minutes to 4 hours. After hardware and software implementation, module and system debugging, the above functions have been realized. This design is simple in structure, low in cost and easy to use, and has application significance in household appliances.)
