胶带输送机胶带纵向撕裂检测系统设计检测系统单片机应用系统软硬件设计毕业论文.doc

徐州工程学院毕业设计论文I图书分类号密级摘要带式输送机是散粒物料运输的主要设备,它广泛用于港口、化工、矿山、电站和冶金等工业领域。皮带撕裂事故时有发生,价值数十万元甚至上百万元的输送皮带,一旦发生撕裂事故,在几分钟内就会全部毁坏,造成巨大的经济损失。随着皮带输送机应用的范围越来越广,其使用量也越来越大,发生撕裂的事故也越来越多。因此,进行皮带撕裂特征的研究具有很重要的理论意义和实际意义。针对现有诸多类型带式输送机胶带纵向撕裂监测保护装置较差、可靠性尚待进一步提高的现状,本文深入研究了传感器的电磁感应原理和监测系统保护装置的可靠性。对整个监测保护装置的软硬件进行了研究设计,研制出一种电磁感应式胶带纵向撕裂监测系统。通过对胶带的运行状态进行不间断地实时监测,监测系统能够在胶带发生纵向撕裂事故时,及时地使输送机停机并发出报警信号,从而大大减少事故的损失。通过设置感应线圈位置检测器和采用地址表管理系统等措施,提高了系统的可靠性。开发了基于AT89C51单片机的实时智能监测软件系统,设计了友好的人机交互界面,具有较强的实用性。关键字带式输送机纵向撕裂监测单片机徐州工程学院毕业设计论文IIAbstractBeltconveyoristhemaindeviceofmodernscatteredmaterialsuccessivetransportation,itswidelyusedinindustrialdomainsasharbortransport,chemicalindustry,mines,powerplantandmetallurgy.Itisunenviablethatthebelttearaccidenthappensoccasionally,whenithappens,thebeltwillbedestroyedwithinseveralminutes,causinghundredsofthousandsdollarslossonitselfvalue,orevenmoreeconomicloss.Withtheconveyorbeltofanincreasinglywiderangeuse,thetearincidentoccursmorefrequently.Thus,itisimportanttostudythecharacteristicsofthebeltteartheoreticalandpracticalandpracticalsignificance.Formanytypesofexistingverticalbeltconveyorbelttearmonitoringdevicestoprotectpoor,pendingfurtherimprovethereliabilityofthecurrentsituation,thisarticleindepthstudyoftheprincipleofelectromagneticinductionsensorsandmonitoringsystemstoprotectthereliabilityofdevices.Thenallofhardwareandsoftwareoftheprotectiondeviceweredesigned,andanewelectromagneticinductiontypemonitoringsystemforlongitudinalripofrubberbeltwasdeveloped.Byincessantlymonitoringtheworkingstateofconveyerbelt,themonitoringsystermwillstopconveyerimmedictelyandgiveoutanalarmwhenthelongitudinalriphappens,therebylosingcausedbytheaccidentcanbereduced.Manymeasures,suchasmountingsensorloopspositiondetectorandadoptingaddresstablemanagesystem,aredevelopedtoimprovethesystemsdependability.AnintelligentrealtimemonitoringsoftwaresystembadedonthemicrocontrollerAT89C51isdeveloped.Afriendlymanmachineinteractioninterfaceandthecommunicationinterfacewithcomputeraredesigned.Allthesemakethesystemmorepracticable.Keywordsbeltconveyorlongitudinalripmonitormicorcontroller徐州工程学院毕业设计论文I目录1绪论.............................................................................................................................................11.1皮带撕裂研究的意义...........................................................................................................11.2皮带撕裂国内外研究现状...................................................................................................11.3论文研究内容与结构安排...................................................................................................72系统的总体方案设计.................................................................................................................82.1胶带纵向撕裂的原因分析..................................................................................................82.2感应线圈的设计...................................................................................................................92.2.1输送带结构....................................................................................................................92.2.2感应线圈的预埋..........................................................................................................102.3皮带纵向撕裂检测系统组成结构.....................................................................................102.3.1检测传感器模块..........................................................................................................112.3.2位置传感器模块..........................................................................................................122.3.3信号处理模块..............................................................................................................122.3.4微控制器......................................................................................................................132.3.5输入输出模块..............................................................................................................132.3.6停机报警电路..............................................................................................................132.4胶带纵向撕裂检测原理....................................................................................................133应用系统硬件设计...................................................................................................................143.1单片机的选用.....................................................................................................................143.1.1单片机简介..................................................................................................................143.1.2AT89C51单片机..........................................................................................................143.2单片机应用系统设计内容.................................................................................................153.3单片机系统硬件设计.........................................................................................................153.3.1数据存储器的扩展.....................................................................................................153.
