PAGEIII摘要随着控制理论和电子技术的发展，工业控制器的适应能力增强和高度智能化正逐步成为现实。其中以单片机为核心实现的数字控制器因其体积小、成本低、功能强、简便易行而得到广泛应用。PLD温度控制器作为一种重要的控制设备，在化工、食品等诸多工业生产过程中，得到广泛的应用。本文主要讨论在过程控制中得到广泛应用的数字PLD控制在单片机温度控制系统中的应用。本文详细阐述了基于单片机的温度控制系统的硬件组成、接口电路及程序编译。并且充分考虑到系统的可靠性，采取相应的保护措施。通过设计表明本文所论述的基于单片机的温度控制系统的设计的合理性及有效性。关键字：单片机；PLD温度控制器；温度控制系统AbstractAlongwithcontroltheoryandelectronicstechnicaldevelopment,theorientationabilityoftheindustrialcontrollerthetobuildupandhighintelligenceturntojustandgraduallybecomereality.Amongthemwithlistslicemachineforthecorecarryoutofthenumbercontrollergetanextensiveapplicationbecauseitsphysicalvolumeissmall,lowcostandstrongfunctionandsimpletoeasilygo.ThePLDtemperaturecontrollerisakindofimportantcontrolequipments,atchemicalengineering,andfood...etc.manyindustrialproductionlinein,getanextensiveapplication.ThistextmainlydiscussesintheprocesstocontrolinthenumberPLDcontrolofgettingtheextensiveapplicationtheapplicationwithinthemachinetemperaturecontrolsystemisatthelistslice.Thistextelaboratedindetailthehardwarecontrollingsystemaccordingtothetemperatureofthelistslicemachineconstitute,connectsapeople'selectriccircuitandproceduretoeditandtranslate.Andfullinconsiderationofthecredibilityofthesystemadopthomologousprotectionmeasure.Passadesignenunciationoriginallywhattextdiscussesaccordingtolistthetemperatureoftheslicemachinecontrolsystemoftherationalityandusefulnessofdesign.Keywords:Thelistslicemachine,PLDtemperaturecontroller,temperaturecontrolssystem目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc261595251"1绪论PAGEREF_Toc261595251\h1HYPERLINK\l"_Toc261595252"1.1概述PAGEREF_Toc261595252\h1HYPERLINK\l"_Toc261595253"1.2温度测控技术的发展PAGEREF_Toc261595253\h1HYPERLINK\l"_Toc261595254"1.3系统方案设计思路PAGEREF_Toc261595254\h2HYPERLINK\l"_Toc261595255"1.4论文主旨及章节安排PAGEREF_Toc261595255\h2HYPERLINK\l"_Toc261595256"2单片机技术简介PAGEREF_Toc261595256\h4HYPERLINK\l"_Toc261595257"2.1单片机介绍PAGEREF_Toc261595257\h4HYPERLINK\l"_Toc261
