生产环境监控系统的研究与实现Researchandimplementationoftheproductionenvironmentmonitoringsystem生产环境监控系统的研究与实现摘要本系统为生产环境监控系统，能够对生产现场环境内的温度、湿度、灯光亮度、可燃气体浓度进行巡检和控制，为了解决生产环境布线繁琐等问题，应用无线蓝牙技术，实现了便携终端设备无线检测和生产环境各项指标的控制，硬件主要由微控制器、信息采集模块和蓝牙模块构成。以ATMEL公司生产的AT89S52单片机为现场主控制器，巡检温度、湿度、光强度、可燃气体浓度同时进行控制，每个检测模块都能独立完成自身功能，同时根据现场主控制器发出的指令对各项环境指标进行实时收集。主控制器负责控制指令的发出，协调各个检测单元进行数据采集，处理测量数据并显示。其中，采用DHT11温湿度传感器构成温湿度检测模块，MQ-2型传感器检测可燃气体浓度，无线通信模块则采用了蓝牙模块HC-06，实现了对生产环境各项指标的无线方式实时监控并可报警。整个系统结构简单，成本低，性能可靠，能够实现对各类生产环境的智能监控。关键词：单片机，温湿度检测，蓝牙技术，环境监控系统ResearchandimplementationoftheproductionenvironmentmonitoringsystemAbstractThesystemfortheproductionofenvironmentalmonitoringsystem,abletopatrolandcontroloftemperature,humidity,lightbrightness,thecombustiblegasconcentrationontheproductionsiteintheenvironment,inordertosolvetheproblemoftheproductionenvironmentofcomplicatedwiring,usingBluetoothwirelesstechnology,realizesthecontrolofportableterminaldevicewirelessdetectionandproductionenvironmentindexes,hardwareconsistsofmicrocontrollertheinformationacquisitionmoduleandaBluetoothmodule,form.ProducedbyATMELcompanyAT89S52microcontrollerasthemaincontrolleroftheinspectionsite,temperature,humidity,lightintensity,concentrationofcombustiblegasarecontrolledatthesametime,eachdetectionmodulecanindependentlyaccomplishitsownfunction,atthesametime,accordingtothesiteofthemaincontrollerinstructionsissuedbythereal-timecollectionofthevariousenvironmentalindicators.Themaincontrollersendsoutthecontrolcommand,coordinateeachdetectionunitfordataacquisition,processinganddisplayofmeasuringdata.Amongthem,usingtheDHT11temperatureandhumiditysensorcomposedoftemperatureandhumiditydetectionmodule,MQ-2sensortodetecttheconcentrationofcombustiblegas,thewirelesscommunicationmoduleisusedtorealizethewirelessBluetoothmoduleHC-06,thewayoftheindicatorsofproductionenvironmentreal-timemonitoringandalarm.Thewholesystemhastheadvantagesofsimplestructure,lowcost,reliableperformance,canrealizetheintelligentcontrolfortheproductionofvarioustypesofenvironmental.Keywords:MicrocontrollerUnit,temperatureandhumiditydetection,Bluetoothtechnology,environmentalmonitoringsystem目录第1章绪论..................................................................................................................11.1课题的研究目的和意义....................................................................................11.2生产监控系统研究现状及发展趋势.................................................................21.3课题的主要研究内容.........................................................................................2第2章系统总体设计方案..............................................................................................32.1总体设计方案......................................................................................................32.2系统的主要技术指标.........................................................................................42.3设计方案论证与器件的选择.............................................................................42.4系统理论分析与计算.........................................................................................7第3章系统的硬件电路设计........................................................................................103.1生产环境监控系统的微控制器简介................................................................103.2AT89S52单片机最小系统的设计....................................................................113.3系统各项参数的数据采集模块设计...............................................................123.4系统的其它外围电路设计...............................................................................17第4章系统软件设计....................................................................................................214.1蓝牙核心协议实现...........................................................................................214.2系统的软件设计...............................................................................................22第5章方案测试与结果分析........................................................................................275.1测试方案............................................................................................................275.2测试条件与仪器...............................................................................................275.3测试结果与数据分析........................................................................................28第6章总结....................................................................................................................30参考文献..........................................................................................................................31附录源程序....................................................................................................................34作者简介及在学期间所取得的科研成果.........................................错误!未定义书签。致谢...............................................................................................错误!未定义书签。第1章绪论1第1章绪论1.1课题的研究目的和意义随着我国经济的发展，工业化进程的不断推进，城市化的发展，人民生活水平不断提高，但随之而来的环境恶化问题也亟待解决。温度、湿度、环境光照情况和有害气体浓度与人类生产、生活紧密相连，这些也是工业、农业生产中最关注、最基本的监测参数，例如农业上农作物的长成温度、湿度非常关键，尤其是光照度的测量与调控，石油、化工、机械、电子等各类生产企业中都需要对温度、湿度和现场环境等情况进行测量与调控，而且随着人类日常生活
