论文_智能水族箱控制系统_鱼缸

哈尔滨工业大学华德应用技术学院毕业设计（论文）I摘要随着人们物质生活的改善和欣赏能力的提高，观赏鱼缸之类的工艺产品逐渐进入了家庭和宾馆、商场等公共场所。但是，目前市场上的观赏鱼缸的水温检测、液位控制、水循环、喂食等操作都需要人为的手工进行，这就给人们带来了很大的麻烦和不便。本文通过对目前大多数水族箱控制设备应用现状的分析和研究，提出了一种多功能的观赏鱼缸智能控制系统的设计方案。该控制系统基于89系列单片机的家庭水族箱控制系统。整套系统以STC89C51单片机为核心芯片，结合传感器技术、继电器原理、C语言编程等技术，集多种控制功能于一体，包括恒温、自动照明、自动换水、自动喂食、自动水循环等，并可根据需要增加控制参数，通过选择不同元器件控制成本。本文从功能设计、元器件选择、硬件电路设计和软件设计等几个方面对该控制系统进行阐述。通过较长时间的运行测试，表明该控制系统运行稳定可靠、操作简单方便、具有多种节电工作模式。同时该系统设计灵活、结构简单、成本低廉，易于规模化生产，可广泛用于家庭和宾馆等安装观赏鱼缸的场所。关键词自动控制；单片机；水族箱；传感器技术哈尔滨工业大学华德应用技术学院毕业设计（论文）IIAbstractWiththeimprovementofpeople'smateriallifeandappreciatingability,suchcraftsasaquariumgraduallyenterhousesandpublicplaceslikehotelsanddepartmentstores.Butasfortheaquariumsfoundinthepresentmarkets,watertemperaturetesting,waterlevelcontrol,waterrecyclingandfoodfeedingareallmanuallyperformed,bringingaboutalotoftroublesandinconveniences.Thisdissertationanalyzesandstudiesthecurrentapplicationsofmostaquariums'controldevicesandmakesoutadesignofmulti-functionalintelligentcontrolsysteminaquarium.Thecontrolsystembasedonthe89SeriesMCUfamilyaquariumcontrolsystem.TheentiresystemtotheSTC89C51MCUasthecorechip,combinedwiththesensortechnology,therelay,Clanguageprogrammingtechnology,setavarietyofcontrolfunctions,includingtemperature,automaticlighting,automaticwaterchanging,automaticfeeding,automaticwatercirculationandsoon,andmayneedtoincreasethecontrolparameters,throughtheselectionofdifferentcomponentsofcostcontrol.Thisarticlefromthefunctiondesign,componentsselection,hardwarecircuitdesignandsoftwaredesignaspectsofthecontrolsystemaredescribed.Throughlongtimeoperationtest,indicatesthatthecontrolsystemisstableandreliable,theoperationissimpleandconvenient,hasavarietyofenergy-savingoperationmode.Atthesametime,thesystemofflexibledesign,simplestructure,lowcost,easytoscaleproduction,canbewidelyusedinfamiliesandhotelsandotherplacesofinstallationofornamentalfish.KeywordsautomaticcontrolSeriesMCUaquariumsensortechnology哈尔滨工业大学华德应用技术学院毕业设计（论文）III目录摘要.....................................................................................................................IAbstract..................................................................................................................II第1章绪论...........................................................................................................11.1选题背景..................................................................................................11.2国内外研究现状及发展趋势..................................................................21.3主要研究内容..........................................................................................31.4课题研究的步骤......................................................................................4第2章鱼缸智能控制系统的总体设计...............................................................52.1概述..........................................................................................................52.2系统的设计要求......................................................................................52.3系统总体方案与功能..............................................................................62.3.1鱼缸智能控制系统的功能组成与控制参数...............................62.3.2系统的硬件结构框图...................................................................72.4主要元器件的选取..................................................................................82.4.1单片机的选取...............................................................................82.4.2键盘控制和LCD数码显示驱动芯片的选取...........................102.5语言工具的选取....................................................................................112.6本章小结................................................................................................12第3章系统的硬件设计.....................................................................................133.1硬件总体结构........................................................................................133.2各模块硬件设计....................................................................................143.2.1时钟电路设计.............................................................................143.2.2键盘控制与显示模块设计.........................................................153.2.3温度控制模块.............................................................................163.2.4其他模块设计.............................................................................173.3继电器控制模块....................................................................................183.3.1继电器的原理.............................................................................183.3.2继电器的选用.............................................................................193.4电路原理图及电路板设计....................................................................193.5本章小结................................................................................................20第4章系统的软件设计.....................................................................................21哈尔滨工业大学华德应用技术学院毕业设计（论文）IV4.1软件设计方法........................................................................................214.2主程序工作流程.................
