题目（中文）基于单片机的恒温箱设计（英文）Designofthermostatboxbasedonsinglechipmicrocomputer摘要：在现实社会生活和生产中，温度对人们的影响无处不在，比如：大棚农业内大棚温度对农作物生长情况的影响，钢铁行业铸铁炉温度对钢铁质量的影响，大产量孵蛋中恒温箱温度对鸡蛋破壳的影响，等等，本文针对小型产品温控器的需求，研究了一种基于单片机的恒温箱。恒温箱可以设定温度的上下限。当温度超过上限和下限时，它可以同时驱动负载和报警。本论文采用数字温度控制器来采集温度信息，本文涉及的恒温箱主要适用于小型产品的温度需求，例如：可作为小宠物的温室或者孵蛋器等，则继电器只需要驱动小型加热片和风扇来调节恒温箱内的温度。本文还使用蜂鸣器和LED作为声光组件的警报。继电器用于控制相应的负载，实现加热或冷却。该恒温箱温度控制系统结构十分简单，操作方便，便于维修，使用广泛。与传统温度计相比，恒温箱内的温度控制系统不仅能实时显示温度，而且温度测量范围更宽，控制更及时更准确，控制负载范围也十分广泛，同时LED发光和蜂鸣器声光报警，主要用于温度测量更精确的地方。关键词：STC89C51单片机；温度控制；DS18B20；恒温箱Abstract：Inactualsociallifeandproduction,theinfluenceoftemperatureonpeopleisubiquitous,suchas:theeffectofgreenhousetemperatureonthegrowthofcropsingreenhouseagriculture,theinfluenceofcastironfurnacetemperatureonthequalityofsteelinthesteelindustry,andthetemperatureofincubatorsinlarge-scaleincubators.Theimpactofeggshelling,etc.,thisarticlefortheneedsofsmallproductthermostats,studiedathermostatbasedonsingle-chipmicrocomputer.Theconstanttemperatureboxcansettheupperandlowerlimitsoftemperature.Whenthetemperatureexceedstheupperandlowerlimits,itcansimultaneouslydriveloadsandalarms.Thispaperusesadigitaltemperaturecontrollertocollecttemperatureinformation.Thethermostatsinvolvedinthispaperaremainlysuitableforthetemperaturerequirementsofsmallproducts.Forexample,theycanbeusedassmallpetsingreenhousesorincubators.Therelaysonlyneedtodrivesmallheatingplatesandfans.Toadjustthetemperatureintheoven.ThisarticlealsousesabuzzerandLEDasanaudibleandvisualcomponentalarm.Relaysareusedtocontrolthecorrespondingloadforheatingorcooling.Thetemperaturecontrolsystemoftheconstanttemperatureboxisverysimpleinstructure,convenientinoperation,convenientinmaintenanceandwidelyused.Comparedwithtraditionalthermometers,thetemperaturecontrolsystemintheincubatorcannotonlydisplaythetemperatureinrealtime,butalsohasawidertemperaturemeasurementrange,moretimelyandaccuratecontrol,andawiderangeofcontrolload.Atthesametime,theLEDlightandbuzzersoundandlightalarm,Itismainlyusedformoreaccuratetemperaturemeasurement.Keywords:STC89C51microcontroller;temperaturecontrol;DS18B20;thermostat.目录1.概述......................................................................................................................................11.1.选题背景............................................................................................................................11.2.选题意义............................................................................................................................12.设计思想...............................................................................................................................22.1.选题简介............................................................................................................................22.2.控制方案..................................................................................................
