远程遥控系统的设计与实现 摘要:本设计是采用计算机技术和无线通信技术实现远程设备的控制，系统包括遥控器端和设备控制器端两个部分。遥控器部分由单片机、按键和无线发射器组成，其功能是通过不同的按键来接收不同的按键值，根据按键值向设备控制器端发送不同的控制代码。设备控制器端也是一个单片机控制系统，由单片机、直流电机、步进电机、显示灯和无线接收器组成，主要功能是根据接收的键值编码实现对不同设备运行状况的控制。系统控制距离较远，应用方便，可应用于家用电子器件的远程控制，还可应用于某些高危险操作下的远程控制，以及户外远距离通信。 本论文描述了远程遥控系统的基本原理、方法和设计过程，论文主要包括：系统方案论证、系统整体结构设计、单元电路设计、系统软件设计等部分，介绍了远程遥控系统设计的基本思路，构建系统框架的方法以及在后期对系统的测试过程。系统方案论证是本设计的前提，系统整体结构设计规划了设计的整体方向和实现过程，是本设计的关键，单元电路设计是系统的最基本模块用来表述系统的工作原理以及各模块的工作原理。 关键词：单片机；无线远程控制；直流电机；步进电机；驱动 Remote control system design and implementation Abstract: This design is to use computer technology and wireless communication technology to realize the remote equipment control. System includes remote terminal and equipment controller end. Remote part is composed of microcomputer, keys and wireless transmitters. It makes different key values according different button pushing and return equal control codes to equipment controller end. Equipment controller end is also a single-chip microcomputer control system, composed by single-chip microcomputer, dc motors, step motor, display lights and wireless receiver composition, and it controls different equipments according to the control codes sent by remote terminal. System control is convenient for use, and can be applied in remote household electronics control, in some high risk operating by remote controlling, and outdoor long distance communication. This paper describes the basic principle, method and design process of remote control system. Thesis mainly includes: system scheme comparison, system structure design, unit circuit design, system software design part and others, introduces design basic idea of remote control system, the way to construct the system framework and later system testing process. System solution argument is the premise. Overall system structure design plans the direction, implementation process and is the key part of the whole design. Unit circuit design is the most basic module and is to describe
