轧机设备的在线监测和故障诊断系统.pdf

摘要随着现代科学技术的进步与发展,设备结构越来越复杂,自动化程度越来越高。随之而来的问题是,一旦关键设备发生故障,吖i仪会造成巨大的经济损失, |f1』且可能危及人身安全,造成重火的社会影响。因此人们对设备的安全、稳定、 K周期、满负荷运行的要求也越来越迫切,希望能及时了解设备运行状态、预防故障、杜绝事故、最大限度地发挥设各的生产潜力。机电设备状态临测与敝障诊断技术研究是根据设备在运行过程中伴随故障而必然产生的振动、噪声、温度、压力等物理参数的变化来判断利识别设备的工作状态和故障,埘故障的危害进行早期识别和预报,做到防患于未然,实现预知检查维修,避免“过剩维修”造成的小经济、不合理现象,它能够节省大量人力物力,为食业和社会带来巨大的经济效益。本论文以安阳钢铁公司高速线材机组为研究背景,详细论述了轧机设备在线监测和故障诊断系统的基本原理、技术手段和诊断方法,并具体论述了系统备组成部分包括硬件和软件的结构、功能及实现方法,最后运用组态软件利诊断专家系统建立了一套基于CAN总线的轧机没备状态在线监测与故障诊断系统。人]二智能技术的发展,为设备故障诊断的智能化提供了可靠性,本文重点分析了基于知识的专家系统在轧机设备故障诊断系统中的应用。并通过工程实践证明,在线监测与人【:智能故障诊断系统实现了设备的实时在线监测,能提供有关i5}备运行参数的准确信息,具有很强的实用性。但是该系统的软件功能还需要进‘步研究利完善,系统的网络功能也有待于进一步开发和扩展。关键词:轧机设备在线监测故障诊断专家系统 Abstract With thedevelopment of themodem technology,血e stnlcture of device e more and plex,and thegrade ofautomation e more andmore following pmblem that once thekey devjce occur fault,itwⅢb—ng greatdanger i”person sa士ety,economy lossand greatsociety what we wish thefol|owing contro】ofme machine:safety,steadX Iong cyc】e,rull 10ad diagnosis technique{s based on thevariation ofthe physical parameters such as vibration,noise,temperature,pressure etc,which was caused by the 伯ultintheprocess ofthen】 technique can calculate山e theearlystage and ca“ foreknow main‰ance Thus avo{ds the unec 0110m{cal and unreasonable Dhenomenon that resultedrrom surplus maintenance andbrings about economic pronts forsociety andenterp—se According tothehigh speed wire&rod plant ofAnYar喀Iron&Steel Co..thi8paper talks about thenecessity ofestablishing on—ljnemonitoring and faultdiagnosis system ofrolling m川 device,describes ponents ofthesystem as well as the structure and thenmction orthe hardware and soRware and also Iherealization method,sets up an on-line monitoring a11dtault diagnosjs system by connguration software and expert system based on CAN bus Based on the deVelopment oftheart饿cialimelligence,this mesis aIso states theapplication ofexpert systenl m theequipment faultdiagnosis thed
