| 摘 要： | 采用AT89C52型号的单片机对传统的电扇系统进行改造,实现对电扇的短距离控制。该设计利用单片机进行红外发送,红外接收,在此过程中对红外进行编码和解码,而后通过不同的编码形成对风扇的不同控制。同时对单片机P0口的输出进行DA变换后,完成对风扇的速度的实时控制。通过仿真实验,验证了该方案的可行性,该设计简单、可靠,具有很强的实用性。

| Abstract: | The model rebuilds the traditional system of fans with the use of AT89C52 microcontroller and realize the short distance control of the fans.The design uses microcontroller for infrared transmission and infrared receiver.In the process the system finishes infrared encoding and decoding.The system can achieve different control according to the different codes.At the same time it can finish the DA conversion of the output of popt po.Then the real-time speed of the fan can be controled.After testing through simulation experiments,the feasibility of the program can be verified.In a word,the design is simple,reliable,and highly practical. |
