Research On XML-Based Electrical Test Coach Software And Enterprise MIS System Data Sharing

At present, the parameter information on the nameplate of the equipment required before testing on electric equipment by electrical test coach needs to be obtained by consulting with enterprise's equipment maintainers on site or by using storage media like USB disk to copy relevant information from the enterprise's MIS system; after electrical test coach completes the test on electric equipment, the test data is delivered over by printed report to the enterprise's equipment maintainers to keep in a file. In this case, working personnel have to log on different system with the same information again and again. To further consummate the software performance of electrical test coach, improve the informatization degree of data sharing between systems, it is an important and urgent task to solve the data sharing between electric test coach software system and enterprise's MIS system.Thesis develops study just against the background of the application projects of the above mentioned engineering. After studying and comparing the relevant technology and strategies about data conversion of heterogeneous database, the paper, combining the design requirement of the engineering project, chooses the highly-flexible and well-extensible heterogeneous data conversion route based on XML, and gives a detailed analysis to the design and realization process of data conversion scheme based on XMLThis thesis mainly studies the following aspects:First, combining the specific application environment and based on the research of wireless network technology, the paper sets up wireless communication platform to connect the terminal of electrical test coach to MIS system interface with open authority in transformer station.Second, based on researching and analyzing ETL architecture and middleware architecture, the paper, combining the advantages of both, puts forward a heterogeneous data conversion architecture which is suitable to the engineering project.Third, based on the actual needs of electric test coach, the paper designs data table structure and relation of the central database. Using XSD's rich element components and data types, the paper designs a set of mode mapping rules representing all types of information and restraint of relation database, and proposes an improvement method based on association list query.Finally, the paper elaborates the realization process of conversion rules file, data export module, data import module deployed in data conversion course,and the design mapping files to test,meet the engineering project needs.
