1、摘 要 I 摘 要 本文介绍的是一个由单片机构成的无线温度控制系统，它利用 8051 单片机 和 DS18B20 及数码管等其他器件实现。温度测量部分工作原理是单片机利用 DS18B20 对温度进行采集，然后进行无线发送，接收端收到信号后，进行解码， 之后实现温度显示。温度控制部分工作原理是由键盘输入欲设定的温度。温度 控制信号送入 CPU 处理，通过 PID 算法输出控制信号，经无线收发电路发射出 去，接受端收到信号经 CPU 处理控制半导体温控装置达到欲设定的温度。本文 对硬件和软件进行了框图设计，protel 原理图设计，程序框图设计，源程序设 计，文后附录了完整源程序。 关键词关键词：

3、ing a part work principle is a single slice machine to make use of the DS18 B20 rightness temperatures to carry on collect, then carry on a wireless to send out, carry on a decoding after receiving to carry to receive signal, after carry out a temperature manifestation.Temperature control part work

4、principle from keyboard importation desire enactment of temperature.The temperature control signal sends into CPU a processing, output control signal through a PID calculate way, Be received and dispatch electric circuit blast-off to go out by wireless and accept to carry to receive signal to control the semi-conductor Wen Kong4s device to attain the temperature of desire enactment through the CPU processing.This text carried on frame diagram a design to the hardware and the software, the pro
