摘要本课题设计的是一套基于单片机控制的仓库温度监控系统，主要是对仓库的温度监控，以保证存储物品的安全。系统以单片机AT89C51为核心，从DS18B20温度检测的数据采集、设定值调整、LED数码管显示电路、报警及输出控制通风机等几个方面出发，详细研究和设计了基于单片机的仓库温度监控的各个部分内容，设计了单片机及其外围电路，并结合一套经典的程序算法。给出了一套合理的基于单片机的仓库温度监控系统的软硬件解决方案。关键字：温度检测；DS18B20；单片机；温度控制AbstractThisissueisasetofdesignbasedonsinglechipcontrolledwarehousetemperaturemonitoringsystem,mainlyforwarehousetemperaturemonitoringtoensurethesafetyofstoreditems.AT89C51microcontrollerasthecoresystem,fromtheDS18B20thetemperaturedetectiondataacquisition,setthevalueofadjustment,LEDdigitaltubedisplaycircuit,alarmandoutputcontrolfan,andseveralotheraspectsofstartingadetailedstudyanddesignofmicrocomputer-basedwarehousetemperaturemonitoringofvariouspartsofthecontentsofthemicrocontrolleranditsperipheralcircuitdesign,combinedwithasetofproceduresfortheclassicalgorithm.Isgivenareasonablemicrocontroller-basedwarehousetemperaturemonitoringsystemhardwareandsoftwaresolution.Keywords:temperaturedetection；DS18B20；microcomputertemperaturecontrol目录摘要............................................................IAbstract...........................................................II引言.............................................................11研究动态..........................................................21.1研究的背景与意义............................................21.2国内外仓库技术现状..........................................21.3仓库测控系统的发展趋势......................................31.4本文的主要工作..............................................42系统的总体设计....................................................53系统的硬件部分设计与实现..........................................63.1单片机介绍..................................................63.1.1单片机概述.............................................63.1.2单片机编程语言介绍.....................................73.1.3系统选择...............................................83.1.4AT89C51引脚功能介绍...................................93.2温度传感器DS18B20.........................................113.2.1温度传感器分类........................................113.2.2DS18B20简介..........................................133.2.3DS18B20的硬件连接....................................144温度监控的系统设计...............................................164.1硬件设计...................................................164.1.1温度检测部分..........................................164.1.2LED数码管显示电路....................................164.1.3报警及控制输出部分....................................174.1.4单片机最小系统........................................184.1.5按键电路设计..........................................214.2软件系统设计...............................................234.2.1系统程序流程图........................................234.2.2单片机软件开发语言....................................244.2.3DS18B20驱动程序......................................25结论.............................................................28参考文献...........................................................29致谢..............................................................30附录一：系统整体硬件电路图..........................
