摘 要本文首先描述了红外线通信原理和红外线接收电路，其次，介绍了直流电机的结构和工作原理，然后，详细的阐述了单片机内部结构及其原理，最后，着重介绍了 PWM 调速和直流电动机正转，反转和制动的原理。直流电机具有良好的调速特性。调速简单，平滑，调速范围大，过载能力强的特点。能满足工业和生活中各种不同的要求，在近代社会进展中起着重要的作用。电机采纳红外遥控功能控制后，整个电机控制更简单、方便、且易于操作。本文中通过红外线按键发射遥控信号，经过红外线接收元件接收信号，然后通过单片机对直流电动机的控制，实现对电动机的启动，降速、升速和停止功能。关键词红外线遥控，直流电机，单片机，调速，制动 PS:毕业设计 14 届 知网查的重复率是 0.3% 拿出来给学弟学妹们参考一下 也可以代做毕业设计 论文全手工 保证不重复 写论文或者做板子都可以 电路设计 单片机软件编程 PLC 也差不多 扣扣 9.1.4.0.7.8.0.9.9 联系我AbstractThis paper describes the principle of infrared communication and the infrared receiving circuit, secondly, introduced the structure and working principle of DC motor, and then, described in detail the internal structure and principle of single chip microcomputer, finally, introduces the PWM control and the DC motor forward, reverse, brake principleDC motor with a speed regulation characteristic of good. Speed control is simple, smooth, wide speed range, the characteristics of strong overload capacity. To meet the requirements of different kinds of industry and daily life, in the development of modern society play a important role. The use of infrared remote control function to control the motor, the motor control more simple, convenient, and easy to operate.This paper through the infrared remote control signal transmitter, through the infrared receiving element receives the signal, and then through the singlechip control of DC motor, the motor starting, speed, speed up and stop function.KEY WORDS: Infrared remote control,...
