基于单片机控制的智能电表抄表系统摘要近年来，随着单片机成本的降低、通信技术的快速发展以及通信技术的多样化，单片机控制结合通信技术，被越来越频繁的运用到人们的生活中。随着我国电网建设不断的深入进行，家用电表数量急剧上升，传统的人力抄表方式费时效率低，而且准确性不高，这个传统的方式已经不符合当今电力改革的要求，研究出智能电表抄表系统是必然的趋势。本论文研究的是“基于单片机控制的智能电表抄表系统”。电表抄表系统采用ST意法半导体单片机STM32F103C8T6和电力载波通信芯片ST7540，以及电力载波电路和电平转换电路等外围电路。在单片机控制下，结合FSK调制解调通信技术的电表抄表系统的硬件和软件实现，绘制对应的电路原理图并且实现、编写单片机代码和反复进行软硬件调试等一系列的相关工作，最终做成抄表电路板和软件管理系统。该系统具有可靠性高、可扩展性强、成本费用低、计量准确等特点。主要用于电能信息的自动抄录，实现了居民住宅的电量自动检测、收费和管理。关键词：智能电表抄表系统；单片机STM32F103C8T6；ST7540；MAX232AbstractInrecentyears,withtherapiddevelopmentofcommunicationtechnology,thediversificationtoreducechipcostandcommunicationtechnology,microprocessorcontrolwithcommunicationtechnology,ismoreandmorefrequentlyusedinpeople'slives.WiththedeepeningofChina'spowergridconstructionhasbeenasharpriseinthenumberofhouseholdelectricmeter,meterreading,humantraditionaltime-consuminglowefficiency,andtheaccuracyisnothigh,thetraditionalwaycannotmeettherequirementsofthereformofelectricpower,smartmeterreadingsystemistheinevitabletrendof.Theresearchofthispaperisthe"smartmeterreadingsystembasedonsinglechipmicrocomputer".AutomaticmeterreadingsystembasedonSTsinglechipmicrocomputerSTM32F103C8T6andmeaninglawsemiconductorpowerloadandpowerlinecarriercommunicationchipSTM7540,circuitandvoltageconversioncircuitandsoon.Underthecontrolofthemicrocontroller,combinedwiththeautomaticmeterreadingsystemB-PSKmodulationanddemodulationofcommunicationtechnology,therealizationofhardwareandsoftware,circuitschematicdrawing,andthecorrespondingprogramandrepeateddebuggingofhardwareandsoftwareofaseriesofrelatedwork,andultimatelymakethemeterreadingcircuitboardandsoftwaremanagementsystem.Thesystemhashighreliability,scalability,lowcost,accuratemeasurementetc..Mainlyusedinautomatictranscribingelectricityinformation,theautomaticdetection,residentialelectricitychargeandmanagement.KeyWords：Thesmartmeterreadingsystem;STM32F103C8T6MCU;ST7540;MAX232目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc418762305"1绪论PAGEREF_Toc418762305\h1
