文档介绍：浙江大学硕士学位论文 XML与EPA功能块相结合的设备描述方案研究姓名:马振芳申请学位级别:硕士专业:控制工程指导教师:冯冬芹 20120309 ,不能采用现有的设备互操作解决方案。为此,开发了基于XML的可扩展的设备描述语言XDDL。在XDDL的基础上,本文扩展了设备描述元素,并与EPA 功能块相结合描述设备。本文主要工作如下。(1)深入研究已有的EPA功能块。在分析功能块的结构、组织调度方法的基础上, 对EPA功能块的通信机制和通信接口进行深入剖析。(2)深入分析XML的优势和XDDL的应用模型与应用过程。XDDL定义的基本结构要素并不完善,不能完备地描述复杂的设备。本文扩展了XDDL的描述元素,设计了界面描述模块、数据描述模块以及通信描述模块,初步建立了一个描述元素库。(3)设计了基于XML和EPA功能块相结合的设备描述方法,、链接对象组态模块和设备管理模块,并测试了各模块的功能。通过开发设备描述元素库,并将其与功能块相结合,,方便了设备开发商和用户。关键词:互可操作技术,EPA功能块,XML,设备描述语言浙江人学硕士学位论文 IV Abstract Abstract Interoperability between devices ofdifferentmodels anddifferentprotocols isalways one ofthekeyproblems thatneed tobe theproposal ofEPA standard, theexisting deviceinteroperable solutions are notsuitable anXML-based extensible device description language一一XDDL Was thebasis ofXDDL,this thesis expanded device description bined with EPA functionblocks todescribedevices. The main work inthisthesis iSlistedas follows: (1)A deep research on theexisting EPA functionblocksWas thebasis ofanalysis anization andscheduling method ofEPA functionblocks,further analysis was conducted munication mechanism munication interface of EPA function blocks. (parison ofadvantages ofXML and theapplication model andapplication process of XDDL were structure elements of XDDL are plete and Can not plicated paper extended element ofXDDL,designed interface module,data module munication module,and built adescription elements library preliminary. (3)Device description method based onXML and EPA function blocksWasdesigned,and thenew method Wasapplied inthe EPA configuration filesmanagement module, linkobjects configuration module and devicemanagement module were designed and the functions ofeachmodule were alsotested.
