| 英文摘要 | With the advent of MES, many problems, such as “information isolated island” and data gap in the information construction of modern enterprise have been solved. As one key to realization of information system integration, MES data integration is the base of it. Along with the continual development of computer technology, system environment, data format and communication mode are getting more and more complexity and diversification. As a new concept, there are various specifications based on XML have been used widely in some fields of Internet such as data representation and exchange, because XML is flexible, expandable and so on. These technologies improve software reuse; enhance cross-platform capability and remote communication, and play a valuable role in expansibility, security, reliability, management and so on in enterprise information integration system. This thesis begins with XML, and concentrates on the research and development of the application of XML technology applied in MES data integration platform. It includes technology background, development, communication protocol, data format, design and implementation, and summarizes at the end. The following are three main aspects of this thesis: 1. Data Acquisition: After having analyzed the application of XML technology in data acquisition, it used OPC data acquisition, based on OPC XML-DA specification, and designed a data communication module, which exchanged data with server and gave play to advantages of XML. 2. Data Communication: Research on communication mechanism and principle, especially the application of SOAP and WSDL which are based on XML, it built framework of data integration platform based on Web service. 3. Data Access: It researched on the application of XML in data storage and image specification. The usage of SVG are discussed here, and it gives play to advantages of vector image and makes easy to modification .Meanwhile, SVG drawings can be interactive and dynamic. It designed image module for data analysis and also database module was done. |
