| Publishing information through the Web, users may monitor thereal-time industry scene by means of the standard browser, it has thesuperiority which traditional configuration software HMI does not have.Web Pulishing makes the application domain of configuration softwareexpand to every society's aspects,therefore The web publishing systembased on the internet/intranet has became the important part ofconfiguration software.Web publishing in the configuration software has two obviousdeficiency at present, 1st: information publishing mostly uses thetechnologies of bitmap or the JavaApplet. The bitmap picture adapts thedynamic transmission request with difficulty in the document size and thedocument content. But JavaApplet has many barriers in the aspects ofspeed, recompility, reusage.2nd, the pattern of Data transmission andexchange has caused the platform limitation because of basing on theDCOM OPC standard. Therefore for a long time, the Web publishingsystem of configuration software continuously has confronted the difficulty of information content oversized, the networkjam, the limitedapplication scope. In order to realizing effective Web data publishing,we change the vision to XML and it's the correlated technology, seekingfor one kind of effective solution.The paper was constructed on the base of practical application " TheIndustry Scene Real-Time Data Integration System (RTDIS)", taking the RTDIS'sgraph development system as the platform, firstly establishing the mappingrelationship between the graph defined in RTDIS and the SVG graph,producing the corresponding transformation method. Then proposing themodel of dynamic Web publishing based on SVG and Web Services. themodel which proposed has realized data dynamic Web publishingbetween isomerism platform; Finally considering the real timerequestment of RTDIS, the paper proposed the optimized methods fromthe aspect of communication: Unifying the multi-thread technology of theJava,Through establishing data buffer, greatly reduced the databaseserver's resources consumption, enhanced the overall performance of thereal-time information publishing system; Through compressing the SVGgraphic file based on the SVG chartmeta description model andoptimizing the SVG graph dynamic analysis method; We manage theXSLT style table through the buffer which slowed down the systemburden of style transforming. Considering this model uses the XMLtechnology, so it greatly surpasses other real-time information publishing models in many ways,suh as timeliness, the flexibility because of Javatechnology the platform realizing, the extension, the probability.The paper finally proposed the model through applying in theRTDIS, which proving the feasibility in configuration software of XMLdiscussed in the paper. |
