【电动机运行监测仪设计与实现20000字（论文）】

总结本文是在大量查阅国内外诸多资料的基础和研究国内外直流电机速度控制现状的基础上，研究直流电机速度控制系统后完成的。因此，本文研究的控制系统具有一定的技术先进性，通过仿真软件Proteus来设计完善电机控制，用虚拟的系统来仿真模拟真实的硬件和软件，不仅达到了目的，而且节约成本，同时，有错误可以方便修改。参数远程监控系统不仅仅可以用来采集电动机的运行参数，也可以采集其它电气设备的参数，比如压缩机的温度，压力等参数的采集和远程监控；还可以运用于智能家居远程监测和控制。所以电动机设备运行参数远程监控系统既可以用于工业上的多种领域，还可以应用于家居监测控制。三相电动机智能保护与监控系统的研制。该系统以智能型电动机保护器为智能节点，以计算机为上位机，通过ModBus现场总线构成通讯网络。保护器以AT89C51单片机为核心，通过交流采样测量电动机的三相电压和电流，并计算出负序、零序电流来实现对电机的综合保护。上位机可以通过ModBus总线远程监测网络上每个保护器的工作状态以及其所控制的电机的运行参数，并能通过保护器控制电机的启动和停止。电动机设备运行参数远程监控系统已经基本完成了电机四项参数的采集、远距离传输与现场显示功能，并且能够在Windows窗体中绘制参数曲线。在采集过程中，AT89C51单片机的内置AD转换器起到了很大的作用，它的转换速率很快，工作性能稳定，还能减少外围电路。在设计中用了RS485通信协议，极好的提高了系统外扩能力，只要子模块的地址和数据串满足协定要求。近几年随着计算机科学技术的快速发展，带动电动机保护装置的设计也日趋向监测功能、保护功能、控制功能一体化、网络化的方向发展。针对这种形势，作者发现本课题的研究仍然存在许多不足的方面，有待于下一步更深入的研究，主要有以下几个方面:（）功能方面还有局限，只有电流/电压计算采样功能，并且由于采样的精度有限，因此对于高次谐波的分析精度不高；（）上位机监控软件的设计及数据分析功能的开发还不够完善；（）TCP/IP协议的功能实现工作还不够完善；（）电动机保护器的基本保护理论仅限于过流比较和基于对称分量法的保护理论，不能实现对转子故障和以及机械故障的保护。迫切需要发现一种新的特种信号作为检测判断的依据。参考文献参考文献刘恩涛,潘宏侠.高精度无刷直流电机伺服控制系统的设计与仿真[J].电子元器件应用.2012(04)张洪宝,王秀和,仲慧.三相异步电动机的MATLAB仿真研究[J].电机技术.2016(04)郭燕飞,荆双喜,孙志毅.基于LabVIEW的电机转子不平衡故障的研究[J].仪表技术.2015(12)马龙博,郑建英.基于组态王和VB的智能仪表实时监控系统[J].自动化仪表.2016(08)王琴琴.监测监控及数据采集(SCADA)系统及其应用[J].胜利油田职工大学学报.2017(03)李太福,余兵.一类基于面向对象的监控系统设计新技术[J].可编程控制器与工厂自动化.2015(09)黄卫华,方康玲,周红军,肖伟.基于组态王和VB的工业远程监控系统[J].冶金自动化.2015(02)林小青,杨德贵,黎湘.一种基于PCI总线的高速数据采集系统的设计[J].微计算机信息.2014(02)马宏忠,胡虔生,黄允凯,王惠庆.感应电机转子断条根数影响分析[J].河海大学学报(自然科学版).2013(05)王颖,章蔚中.基于LabVIEW的电机测控系统设计[J].微计算机信息.2015(28)徐小来,王莉,谢一静.基于Matlab的异步电动机定子绕组故障仿真[J].电气应用.2015(09)余琼芳,董爱华,冉正云.基于DSP的大中型异步电动机故障诊断模糊专家系统[J].煤矿机电.2013(06)齐利民,刘国海,贾洪平.电动车用无刷直流电机无位置传感器控制[J].微电机.2011(11)李珍香,李全福.Proteus仿真软件在微机原理与接口技术课程实验教学中的应用[J].计算机教育.2015(09)宋凌锋,于霞,程树康.异步电动机综合保护及相关实用电路[J].中小型电机.2015(03)郎兵,李继红,周长青.电动机综合保护中过负载保护模型的研究[J].电力情报.2016(04)陈永亭,李芙英,王维俭.异步电动机微机保护装置的研制[J].电子技术应用.2017(11)肖纪立,徐志斌,黄圣国.智能型多功能电机保护装置的研制[J].电子技术应用.1998(03)边璐.Proteus在计算机电路课程中的应用[J].信息系统工程.2013(10)蔡秋花,马菲,张文英.一种无刷直流电机测控系统设计[J].控制工程.2016(S1)YangyangLi,HongzhuShi,LichengJiao,RuochenLiu.QuantumevolutionaryclusteringalgorithmbasedonwatershedappliedtoSARimagesegmentation[J].Neurocomputing.2012JunSun,XiaojunWu,VasilePalade,WeiFang,Choi-HongLai,WenboXu.Convergenceanalysisandimprovementsofquantum-behavedparticleswarmoptimization[J].InformationSciences.2012JunSun,WeiFang,VasilePalade,XiaojunWu,WenboXu.Quantum-behavedparticleswarmoptimizationwithGaussiandistributedlocalattractorpoint[J].AppliedMathematicsandComputation.2011(7)RosenblattF.Theperceptron:aprobabilisticmodelforinformationstorageandorganizationinthebrain.PsychologicalReview.1958HopfieldJJ.Neuralnetworkandphysicalsystemswithemergentcollectivecomputationalabilities.ProceedingsoftheNationalAcademyofScience.2015RumelhartDE,McClellandJL.ParallelDistributedProcessing:ExplorationsintheMicrostructureofCognition.ParallelDistributedProcessing:ExplorationsintheMicrostructuresofCognition.2016[8]SinnasamyR,Naidu,etal.UseofNeuralNetworksforSensorFailureDetectioninaControlSystem.IEEEControlSystemsMagazine.2013PenmanJ,SeddingHG,LloydBA,etal.Detectionandlocationofinterturnshortcircuitsinthestatorwindingsofoperatingmotors.IEEETransactionsonEnergyConversion.2014致谢本论文是在老师的悉心指导下完成的。老师渊博的专业知识，严谨的治学态度，精益求精的工作作风，诲人不倦的高尚师德，严以律己、宽以待人的崇高风范，朴实无华、平易近人的人格魅力对我影响深远。不仅使我树立了远大的学术目标、掌握了基本的研究方法，还使我明白了许多待人接物与为人处世的道理。本论文从选题到完成，每一步都是在老师的指导下完成的，倾注了老师大量的心血。在此，谨向老师及其各位授课老师表示崇高的敬意和衷心的感谢！附录#include<STC12C5A.H>#include<INTRINS.H>#include"UCRT.c"#include"LCD.c"#include"CRC.c"sbitLE=P1^0;sbitLED1=P2^1;//shousbitLED2=P2^2;////fasbitKEY1=P3^3;sbitKEY2=P3^4;sbitKEY4=P3^6;sbitKEY5=P3^7;
