I花式喷泉的PLC控制摘要花式喷泉是近年来出现的一种园林建筑与花式观赏相结合的一种产物。随着可编程控制器在我国的迅速发展，对花式喷泉的控制要求也越来越高，使得越来越多的控制部分需要可编程控制器来实现。本文结合任务设计书的要求，以花式喷泉为研究对象，采用了S7-300系列PLC作为喷泉的控制器。对花式喷泉的控制系统的总体功能进行了分析，阐述了可编程控制器的组成和工作原理。提出了喷泉硬件的各组成模块及详细的硬件模块设计方案，并对控制方式进行了设计和程序的编写。本设计改善了喷泉系统的控制品质，并真正地达到了实时控制的要求。关键词：PLC；喷泉；控制系统IIFancyfountainPLCControlAbstractFancyfountaininrecentyearstheemergenceofalandscapearchitectureandfancywatchaproductofacombination.WiththeprogrammablecontrollerinChina'srapiddevelopment,fancyfountaincontrolrequirementshavebecomemoresophisticated,makingmoreandmorecontroloversomeoftheneedsprogrammablelogiccontrollertoachieve.Inthispaper,thetaskdesigndocumentrequirementstofancyfountainastheresearchobject,usingS7-300seriesPLCasthefountaincontroller.Fancyfountaincontrolsystemsfortheoverallfunctionoftheanalysis,describedthecompositionandtheprogrammablecontrollerworks.Fountainmadeoftheconstituenthardwaremodulesandthedetaileddesignofhardwaremodules,andcontrolthemannerandproceduresforthepreparationofthedesign.Thisdesignimprovesthefountainsystem,controlquality,andtrulyachievethereal-timecontrolrequirements.Keywords:PLC;fountain;controlsystemIII目录第1章绪论............................................................11.1喷泉的发展.........................................................11.1.1我国喷泉的发展................................................11.1.2喷泉的应用状况................................................11.1.3现代喷泉重出现的问题..........................................21.2喷泉的种类.........................................................31.3喷泉中的一些新技术.................................................31.4设计的主要研究内容及安排...........................................3第2章方案分析..........................................................52.1主控制器方案分析...................................................52.2主控制器方案的选择.................................................62.3喷泉控制方案分析...................................................62.4喷泉控制方案的选择.................................................72.5喷泉的控制要求.....................................................7第3章花式喷泉的硬件设计................................................93.1硬件的选择.........................................................93.1.1PLC的选择方案.................................................93.1.2水泵的选择方案................................................93.1.3喷头的选择方案...............................................103.2控制面板..........................................................10第4章系统的软件设计...................................................124.1花式喷泉的PLC控制流程图..........................................124.2I/O模块的选择.....................................................124.3花式喷泉的I/O分配................................................134.4PLC的I/O地址分配简介.............................................134.5软件的选用........................................................134.6系统主程序........................................................144.7系统程序的可行性..............................
