摘　　要： 设备监测和故障诊断一直以来都是工业领域研究的热点,一方面人们对设备的安全、稳定、满负荷运行、可靠性的要求逐步提高;另一方面网络技术,计算机技术、信号分析与处理技术越来越广泛而成功应用,使得当今监测诊断技术日新月异,基于网络的远程监控和故障诊断模式越来越受到国内外的重视。正是在这一背景下,本文结合武钢炼铁厂出铁场除尘风机监测和诊断课题的开发实践做了相关的研究工作,文中着重从应用上结合相关理论技术来研究了风机监测和诊断的技术实现,对其中的关键技术进行了分析,对需要解决的问题作了较为深入的探讨。 /(1/)对于网络化应用环境下的监测与诊断系统的实现技术进行了深入研究,分析对比了Client//Server和Browser//Server两种常用的远程监测诊断的实现模式各自的优缺点,提出建立B//S模式的远程在线监测与故障诊断系统。结合远程监测与诊断系统的特点和具体的应用需求,提出了远程监测与诊断系统的总体设计思想,设计了系统的总体功能结构由现场数据采集系统、远程在线监测系统、远程信号分析和故障诊断系统构成,并对各部分的功能进行了分析和设计。 /(2/)远程在线监测系统的作用是对风机的运行状态进行全面监测,判断监测信号是处于正常或非正常状态,当出现异常状态时,给出报警提示。远程监测是远程诊断的基础,它为远程预报和故障诊断提供最原始也是最重要的依据。对远程监测模块的实现做了深入的分析和论述,研究了监测系统的功能和结构,探讨了利用JAVA技术和数据库技术实现远程监测界面,故障报警功能等。 /(3/)远程故障诊断系统包括远程信号分析和远程故障诊断两个子系统。在远程信号分析系统中研究了如何综合运用时域、频域、时频域多种分析方法,准确地提 Monitoring and fault diagnosis of equipment have been the research hotspot in the industry field. On the one hand, the demand of safety, stabilization,running at full load and reliability is upgraded step by step; On the other hand, the technology of network, computer and signal analysis and processing have applied wildly and successfully. It makes the technology of monitoring and fault diagnosis developed quickly nowadays. The mode of long-distance monitoring and fault diagnosis based on network is paid more attention by the domestic and overseas. Under such background, combined with the development and practice of monitoring and diagnosis of the dust-removing fan of cast house of pudding plant of Wuhan Iron /& Steel Corporation, we do some interrelated research about the realized technology of monitoring and diagnosis of the dust-removing fan basically in the aspect of application combined with interrelated theory and technique. We analyze the key technique and discuss the issues that need to be solved deeply. /(1/) The realized technology of monitoring and diagnosis system based on network application environment is researched profoundly. We analyze and compare the strongpoint and defect of Client//Serve mode with the ones of the Browser//Server mode that are the common realized mode of long-distance monitoring and diagnosis and put forward the building of such a system based on the B//S mode. Combined with the characteristics and concretely applied demand of the long-distance monitoring and diagnosis system, we put forward the overall designed idea of such system, devise the whole function framework of the system which is composed with several subsystems, such as the local data acquisition system, long-distance on-line monitoring system, long-distance signal analysis and fault diagnosis system etc. And we analyze and devise the function of each part. /(2/) The function of long-distance monitoring system is monitoring the running state of fan comprehensively, judging normality or abnorm
