文档介绍：摘要
计算机的出现是人类的生活发生了翻天覆地的变化。单片机也是伴随着计算机的产生而产生和发展的。也可以毫不夸张地说,单片机技术的出现给现代工业测控领域带来了一次新的技术革命。它使原来用分立元件进行的控制,转变到用程序进行控制,使控制的可靠性增加了,功能增多了,成本降低了,控制更灵活了。最重要的是,使学习和掌握测控技术变的更加容易。许多非自动化控制专业的人员也能毫不费力地,甚至通过自学单片机技术而成为此专业的控制专家。因单片机技术的应用而产生了许多新兴的专业,它开辟了更多的单片机应用领域,如工业控制,自动化设备,机床,数据采集和处理,智能化仪表,办公自动化,家电,汽车,医疗器械等。越来越多的人在关心,学习,从事单片机应用技术。单片微型计算机是把组成微型计算机的各个功能部件,即中央处理器CPU,随机存储器RAM,只读存储器ROM,I/O接口电路,定时计数器以及串行通讯接口等部件制作在一块集成芯片中,简称单片机。它是随微型计算机的发展而产生和发展的,在智能化仪表,检测和控制系统领域都有着广泛的应用。

Abstract
puter is that earthshaking change happened in human being's life. The monolithic machine is also e into being but e into being and develop to be panying puter's. Also can exaggerate a field not in the least saying monolithic machine technology appearing is measured and controlled a field having brought about a new technological revolution by modern industry. It has used controlling using ponent to be in progress in the first place , the change has controlled to using procedure to be in progress , the reliability that the messenger controls has increased by , the function has increased by , cost has reduced , has controlled more nimbly. The most important being, is especially easy to make TT&C Telemetry Tracking mand studying and grasping changeable. Many are not that the personnel who automates to control special field can't can a field strenuousness without any, even by studying the monolithic machine independently
