第二章 系统总体方案设计

2.1设计的内容及原理

该设计主要牵涉到无线电的发射和接收、数字信号和调制传输以及单片机软件的选择及系统内部程序设计等几大方面。该系统主要由无线发射和无线接收模块以及各通信模块组成。包含发射和接收模块的电路设计，单片机的选择和使用，极其内部通信模块的选择与制作，和转换程序的编写。家用电器单个或多个有线连接控制，使得其使用很不方便。因此越来越多的家用电器开始采用无线控制技术来方便控制使用，通过采用无线传输技术使得家电可以非触式控制。控制距离和高度都大大的满足了人们生活工作的正常需要。因此该无线控制技术具有很高的实用价值。家用电器电源无线控制系统的设计包括无线电的发射和接收，数字信号的调制与解调（来传达控制信息），单片机的选择及系统内部程序设计等几大方面。该系统由无线发射和无线接收模块以及各通信模块组成。设计过程包含发射和接收模块的电路设计，单片机的选择使用，及其内部通信模块的选择与制作。通过该系统来达到人们对家用电器的控制需求。 2.2设计的初步思路

第四章 PIC16F877单片机概述

4.1单片机的发展和应用

4.1.1单片机的历史发展概况

单片机技术发展十分迅速，产品种类已琳琅满目。纵横整个单片机技术发展过程，可以分为以下三个主要过程： 一、单芯片微机形成过程

1976年，Intel公司推出了MCS-48系列单片机。该系列单片机早期产品在芯片内集成有：8位CPU、1K字节程序存储器（ROM）、64字节数据存储器（RAM）、27根I/O线和1个8位定时/计数器。

此阶段的主要特点是：在单个芯片内完成了CPU、存储器、I/O接口、定时/计数器、中断系统、时钟等部件的集成，但存储器的容量较小，寻址范围小（不大于4K），无串行接口，指令系统功能不强。 二、性能完善提高阶段

1980年，Intel公司推出MCS-51系列单片机。该系列单片机在芯片内集成有：8位CPU、4K字节程序存储器（ROM）、128位字节数据存储器（RAM）、4个8位并行接口、1个全双工串行接口和2个16位定时/计数器。寻址范围为64K，并集成有控制功能较强的布尔处理器完成处理功能。

此阶段的主要特点是：结构体系完善，性能已大大提高，面向控制的特点进一步突出。现在，MCS-51已成为公认的单片机经典机种。 三、微
