触摸屏自动售货机控制系统的设计

I题目触摸屏自动售货机控制系统的设计英文题目TheDesignofcontrolsystemofTouchScreenAutomaticVending摘要随着社会不断的进步，人们的物质文化与精神文化都在明显的提高，这样表现在出入各个场所采用信用卡支付现金，一人一部手机，节假日看电影，坐地铁，听音乐会，逛步行街...这个现象都表明在物质生活提高的同时，精神生活也提高了，随处可见的出租车，还有随处可见的售货机，这在繁华的都市也已成为不可缺少的一个为市民提供方便的一部机器，只需要投几个硬币就可以选择自己想要的物品。随着工业自动化的发展，基于PLC越来越普及，几乎遍布所有自动化领域，与之相应的人-机交互系统也应运而生，并得到同步发展。液晶显示工业触摸屏是人-机交互系统中一颗耀眼的明星，由于高可靠、长寿命、高性能，使触摸屏在工业自动化行业中倍受重视。本文介绍了触摸屏自动售货机的基本原理以及工作流程，然后以一次交易过程为例，把交易过程分为几个程序块，然后分别对程序块进行编辑。具体说明了可编程控制器在自动售货机中的作用。程序涉及到了自动售货机工作的绝大部分过程。利用PLC和触摸屏控制的自动售货机提高了系统的稳定性，保证自动售货机能够长期稳定运行。【关键词】PLC；触摸屏；梯形图；I/O点的分配IIAbstractAlongwiththesocialcontinuousprogress,thepeople'smaterialcultureandthespiritualcultureallintheobviousexaltation,expressthusatcomeinandgoouttheadoptioncreditcardintheeachplacetopaytopaybycash,acellularphoneofoneperson,thestanzadayoffgotothemovie,sittingthesubway,gototheconcert,strollingtheonfootstreet...Thisphenomenonsallexpressatthetimeofphysicalliferaise,thespirituallifealsoraised,everywhereitisthusclearthatoffor-rentcar,stillhaveeverywhereitisthusclearthatofbeveragesellgoodsthemachineautomatically,thisamachinethatprovidestheconvenienceforthecitizenrythatalsohasbecometheindispensabilityintheprosperouscity,needtothrowthebeveragethatafewcoinscanchoosetheoneselftowantonly.Withthedevelopmentofindustrialautomation,basedonthePLCisbecomingincreasinglypopular,almostalloverthefieldofautomation,withtheappropriateperson-machineinteractionsystemalsocameintobeing,andthesimultaneousdevelopmentofTouch-screenliquidcrystaldisplayindustryispeople-machineinteractionsysteminadazzlingstar,duetothehighreliability,longlife,highperformance,touchscreensothatintheindustrialautomationindustry,muchattentionIIIto.Abstract:ThisarticleintroducedTouchscreenvendingmachine’sbasicprincipleaswellastheworkflow,thentakeatransactionprocessasexamples,dividesintoseveralblocksthetransactionprocess,thencarriesontheprogrammingseparatelytotheblock.Explainedtheprogrammablecontroller’sinvendingmachinefunctionspecifically.Theprocedureinvolvedthevendingmachineworkmajorpartprocess.Enhancedsystem’sstabilityusingthePLCandTouchingscreencontrol’svendingmachine,theguaranteevendingmachinehasbeenablethelong-termstabilitymovement.【Keywords】PLC;Touchingscreen;Trapezoidalchart;I/OpointofthedistributionIV目录前言................................................................................................................................1第一章绪论.................................................................................................................21.1自动售货机的理论背景与实际意义.................................................................21.2触摸屏自动售货机设计的主要内容.................................................................31.3触摸屏自动售货机设计的基本思路.................................................................3第二章触摸屏技术.....................................................................................................42.1触摸屏概述.........................................................................................................42.1.1触摸屏的发展.............................................................................................................42.1.2触摸屏的工作原理.....................................................................................................42.1.3触摸屏的基本类型.....................................................................................................52.1.4触摸屏的应用.............................................................................................................52.1.5触摸屏技术的发展趋势.............................................................................................62.2触摸屏的特点功能.............................................................................................62.2.1功能..............................................................................................................................62.2.2坐标系统......................................................................................................................72.2.3定位系统......................................................................................................................72.3触摸屏设计软件.................................................................................................72.3.1触摸屏的发展潜力.....................................................................................................7V2.3.2触摸屏设计软件的种类.............................................................................................8第三章方案论证与设计.............................................................................................93.1控制系统设计原则.............................................................................................93.2方案的选择与设计.............................................................................................93.2.1继电控制.....................................................................................................................93.2.2单片机控制...............................................................................................................103.2.3PLC控制..........................................................
