基于51单片机的安全带语音报警系统设计摘要单片机在生活中的应用无处在，洗衣机上的控制板，电磁炉上的控制板、电动力车的控制器、导弹的导航装置，计算机网络通信和数据传输，实现工业上的自动化实时监控以及对数据进行实时处理。该微控制器被广泛用于在该领域的智能管理和过程控制，如在家电上、精密仪器仪表、医疗设备、家电产品，医疗设备、海陆空运输设备上。本文设计了基于51单片乘客安全带监控系统，通过压力传感器模拟人体坐在座位上，若压力传感器检测到压力的存在，这是如果到位开关没有拨上，则代表安全带没有系上，这时语音播报系统会进行提示，当把到位开关拨上，则语音播报系统停止提醒。在不同的环境下测试和验证模块的性能，本设计对安全带的实时功能进行了试验验证，最终的结果是通过了项目的要求。关键词：单片机，压力传感器，安全带，电源设计Designofvoicealarmsystembasedon51singlechipmicrocomputerAbstractTheapplicationofsinglechipcomputerinlifeisnotinplace,thecontrolboardonthewashingmachine,thecontrolboardontheelectromagneticfurnace,thecontrolleroftheelectricpowercar,thenavigationdeviceofthemissile,thecomputernetworkcommunicationanddatatransmission,thereal-timecontrolanddataprocessingoftheindustrialautomationprocess.Themicrocontrolleriswidelyusedinthefieldofintelligentmanagementandprocesscontrol,suchashomeappliances,precisioninstruments,medicalequipment,householdappliances,medicalequipment,sea,landandairtransportationequipment.Thisdesignisbasedona51singlechippassengerseatbeltmonitoringsystem,throughthepressuresensortosimulatethebodysittingontheseat.Ifthepressuresensordetectstheexistenceofpressure,thisisiftheswitchisnotputon,thentheseatbeltisnottied,thenthevoicebroadcastsystemwillbeprompted.Whentheswitchisputontheswitch,thevoicebroadcastsystemstopsreminding.Testandverifytheperformanceofthemoduleindifferentenvironments.Thisstudyteststhereal-timefunctionoftheseatbelt,andthefinalresultisthroughtherequirementsoftheproject.Keyword:Singlechip、Pressuresensor、Safetybelt、Powersupplydesign目录1、绪论........................................................................................................................................................11.1研究背景及其意义......................................................................................................................................11.2本文的主要研究内容及论文结构安排.......................................................................................................12、方案的设计与论证..................................................................................................................................22.1单片机芯片的选择......................................................................................................................................22.2称重传感器的选..........................................................................................................................................22.3A/D转换器的选择........................................................................................................................................32.4声音报警电路方案的选择..........................................................................................................................43、硬件电路的设计......................................................................................................................................53.1功能分析与结构设计....................................................................
