基于单片机的室内灯光智能控制系统的设计

商丘学院本科毕业设计I摘要此篇论文主要是根据大学教室中灯的日常使用情况以及教室对灯光的需求这些问题，研究并设计出了一种基于单片机控制的室内灯光智能控制系统。此控制系统的核心部件就是AT89S51单片机，系统利用热释红外人体传感器这个器件来对人体的是否存在进行检测，并且利用光敏三极管组成的电路对室内的自然光照强度进行检测；此控制系统根据教室对光照的需求来进行合理的控制灯的关闭与打开，首先，它先通过对人体存在的信号以及室内光照强度信号进行综合的分析与判断，对信号的处理以后，通过系统的反馈来完成对教室内的灯光的智能控制，这样就大大减少了教室用电的浪费。此外系统还具备了报警功能；并且它还采用了软/硬件的“看门狗”，它可以增强系统的抗干扰能力。该系统能够达到各种院校对教室灯光控制的要求，最终就可以达到节能的目的。关键词：单片机；智能控制；热释红外传感器；X5045商丘学院本科毕业设计IIAbstractCipianthesisisbasedontheuniversityclassroominlightofdailyusageandthedemandforclassroomlightingtheseissues,researchanddesignofindoorlightingintelligentcontrolsystembasedonmicroprocessorcontrolled.CorecomponentsofthiscontrolsystemisAT89S51microcontroller,thesystemusesthehumanbodypyroelectricinfraredsensorthisdevicetothehumanbodytodetecttheexistenceanduseofthecircuitphototransistoroftheindoornaturallightintensityisdetected;thiscontrolsystemaccordingtoclassroomtoLightneedstobeclosedandanopenandreasonablecontroloflight,first,thatthefirstsignalbythepresenceofthehumanbodyandinteriorlightintensitysignalintegratedanalysisanddeterminethefutureofthesignalprocessingbythefeedbacksystemtocompletetheclassroomlightingwithintheintelligentcontrol,thusgreatlyreducingthewasteofelectricityclassroom.Inadditionthesystemalsohasthealarmfunction;anditusesahardware/softwarewatchdog,itcanenhancetheanti-jammingcapability.Thesystemcanachieveavarietyofinstitutionsforclassroomlightingcontrolrequirements,mostmechanizedcansaveenergy.Keywords:SCM;intelligentcontrol;pyroelectricinfraredsensor;X5045商丘学院本科毕业设计III目录1绪论...........................................................................................................................................11.1课题研究的目的与意义.................................................................................................11.2采用智能照明控制系统的优势.....................................................................................11.3智能照明控制系统的研究现状.......................................................................................22教室灯光控制器简介与方案分析...........................................................................................22.1大学教室照明控制现状...................................................................................................22.2教室灯光控制器简介.......................................................................................................22.3系统控制方案分析...........................................................................................................22.4本章小节...........................................................................................................................33系统控制模块的硬件设计.......................................................................................................33.1系统控制模块的硬件构成...............................................................................................33.2系统控制的主要硬件电路...............................................................................................43.2.1系统主控电路.........................................................................................................43.2.2系统供电电路.........................................................................................................53.2.3系统复位电路.........................................................................................................63.2.4数据采集电路.........................................................................................................73.2.5系统时钟电路.......................................................................................................103.2.6继电器驱动电路...................................................................................................113.2.7蜂鸣报警电路.......................................................................................................123.2.8按键控制电路.......................................................................................................134控制模块软件设计.................................................................................................................134.1系统监控主程序模块......................................................................................................144.1.1系统自检初始化...................................................................................................144.1.2定时中断处理设计...............................................................................................144.2数据采集模块.................................................................................................................154.2.1人体存在传感器的优缺点...................................................................................154.2.2数据采集软件的实现...........................................................................................154.2.3人体存在传感器的抗干扰措施...........................................................................16商丘学院本科毕业设计IV4.2.4人体存在传感器的安装要求...............................................................................174.3时钟模块.........................................................................................................................174.3.1数据输入输出....................................................
