Applied Research The Technology Of XML In Human Machine Interface

This thesis according to the found project of Hefei University of Technology "The research of application XML in Human Machine Interface (HMI)", on the basis of the technology of XML and Java, studies the trait of SVG images which was recommended by W3C and the SOAP protocol which is one of the.criterion of Web Service, especially researches the converting AutoCAD figure into SVG figure, SVG images dynamic Web release technology based on SOAP.At first , the thesis introduces the original, development, function characteristic and application actuality of HMI, and then analyses the shortage of HMI at present. Secondly, the original, development and application prospect of XML, SVG and SOAP are introduced, then the paper discusses the basic conception, architecture of Web Services based on SOAP and the layer model, composing structure, kernel API of J2EE software architecture based on Java 2 platform. Thirdly, the mapping relation between AutoCAD's object and SVG's element is established based on particular analysis of AutoCAD drawing database by using the AutoCAD drawing developing sofeware, and then the converting method is given. Finally, presents a dynamic Web release framework model among wide range of environments by using SOAP and J2EE, then we introduce the framework according to the layer model of J2EE.The last part of the thesis gives a running example of Real-time control system, which proves the feasibility of application XML in Human Machine Interface.
