【摘要】 基于Internet的异构故障诊断系统集成研究,目的是通过Internet,使得传统的或者先前开发的一些远程诊断系统的相关服务,能够在异构条件下被其他系统所调用,形成诊断服务共享。目前,各个企业、地区、领域在不同时期已经建立了一些故障诊断系统,然而它们侧重于不同的生产设备,开放性还很不够,系统间不能有效地进行知识共享。在技术实现上采用的平台、协议、体系结构各不相同,对于某种可通用的服务,由于各系统平台之间不能互连、互通,造成了人力、财力的巨大重复性投入。本文从系统集成的理论出发,着重从以下几个部分进行了研究:1.理论上构建集成的总体框架。根据远程诊断系统的一般结构,分析诊断系统集成的要求,比较目前流行的四种集成模型,最后选择Web Service技术来构建集成平台,并提出与多代理技术相结合的思想,建立了系统集成的总体框架。本文并进一步从集成平台的两个方面进行研究:Web Service封装和服务的发现。2.根据集成平台,一方面从理论上研究Web Service如何封装诊断系统相关服务,并详细阐述了Web Service技术(包括XML、SOAP、WSDL、UDDI);另一方面以COM+/MIDAS远程旋转机械故障诊断系统提供的初步诊断服务为封装对象,采用Delphi 7的Web Service组件进行服务器端的开发,采用IntraWeb组件进行客户端开发,运行结果说明了通过接口信息,利用Web Service技术,该项服务就能被其他系统所调用。3.分析和比较四种Web服务发现机制,结合本文实际需要,采用ASP技术建立动态网站,来进行各诊断系统接口信息的共享。以Dreamweaver8为主要开发工具,Access2003作为后台数据库,IIS5.1作为Web服务器,主要实现用户登录注册、管理员入口、诊断服务接口信息查询和提交、文件上传功能。本文以理论研究为基础,在分析开发环境和步骤之后,研究了Web Service技术的实现,以及信息服务平台的建设,为构建集成平台,实现协同诊断作铺垫。更多还原

【Abstract】 The purpose of the study, which is integration research on fault diagnosis system of heterogeneous configuration based on Internet, is to apply traditional systems or previously remote fault diagnosis system to the environment with some heterogeneity, so resources can be shared.Nowadays, many distributed remote fault diagnosis systems have been built in various fields, companies and areas at different times depended on theirs own demands. But these systems emphasized particularly on different objects and could not be open to others easily. The knowledge also could not be shared among them. So when we need universal services, a lot of manpower and resources may be wasted because of the problem.From the frame and system of the study, knowledge of correlative domain is analyzed and researched in the paper. The kernel of the dissertation discusses mainly several parts as follows:1. The overall framework of integration platform is researched theoretically. This part includes the analysis and comparison of four popular integration models. Web Service can pack the former system and the center of diagnosis system can manage or dispatching customers by register data. So Web Service is choosed to build the integration platform. The paper does researches mainly on two parts of the framework: how to pack systems and service discovery.2. XML(eXtensible Markup Language), SOAP ( Simple Object Access Protocol),WSDL(web service description language ),UDDI and service discovery are studied in detail. Aiming at integration of diagnosis system built by the technology of COM+/MIDAS, how to pack it and carry it out by software is concentrated on mainly. By the analysis, Delphi 7 is most suitable tool for me to develop it.3. Methods of service discovery are provided .Instead of UDDI registry, a dynamic website is built to achieve service discovery and interface information share. Choose the rotating machinery as the object and use ASP as main technology.Choose IIS5.1 (Internet Information Server 5.1) as server. The main tool is Dreamweaver 8 and Access 2003 is used as software platform of database serve. The system achieved main functional modules such as login, registry, inquiry of interface information, file upload.The paper is based on theory. After the analysis of development steps and environment, study how to achieve web service and how to build a platform for sharing the integration information. All of that can make foundation for collaborative diagnosis.更多还原
