【正文】 基于單片機(jī)的溫度控制系統(tǒng)的設(shè)計(jì)摘要： 本設(shè)計(jì)以AT89S51單片機(jī)為核心的溫度控制系統(tǒng)的工作原理和設(shè)計(jì)方法。溫度信號(hào)由溫度芯片DS18B20采集，并以數(shù)字信號(hào)的方式傳送給單片機(jī)。文中介紹了該控制系統(tǒng)的硬件部分，包括：溫度檢測(cè)電路、溫度控制電路、PC機(jī)與單片機(jī)串口通訊電路和一些接口電路 。單片機(jī)通過(guò)對(duì)信號(hào)進(jìn)行相應(yīng)處理，從而實(shí)現(xiàn)溫度控制的目的。文中還著重介紹了軟件設(shè)計(jì)部分，在這里采用模塊化結(jié)構(gòu)，主要模塊有：數(shù)碼管顯示程序、鍵盤(pán)掃描及按鍵處理程序、溫度信號(hào)處理程序、繼電器控制程序、超溫報(bào)警程序。 關(guān)鍵詞：AT89S51單片機(jī) DS18B20溫度芯片 溫度控制 串口通訊10畢業(yè)論文外文摘要Title Based on Monolithic Integrated Circuit39。s Temperature Control System39。s Design AbstractThis design take at89S51 monolithic integrated circuit as core temperature control system39。s principle of work and design method. The temperature signal by the temperature chip DS18B20 gathering, and transmits by digital signal39。s way for the monolithic integrated circuit. In the article introduced this control system39。s hardware part, including: Temperature examination electric circuit, temperaturecontrol circuit, PC machine and monolithic integrated circuit serial port munication channel and some interface circuit. The monolithic integrated circuit through carries on corresponding processing to the signal, thus realizes the temperature control goal. In the article also emphatically introduced the software design part, uses the modular structure in here, the main module includes: Nixietube display sequence, keyboard scanning and pressed key disposal procedure, temperature signal processing procedure, blackwhite control procedure, excess temperature warning procedure.Keywords：AT89S51 Monolithic Integrated Circuit ；DS18B20 Temperature Chip；Temperature Control；Serial Port Communication目 次1 引言…………………………………………………………………………………12 設(shè)計(jì)要求……………………………………………………………………………13 工作原理
