The Design And Implement Of Digital Integrated Maintenance And Support Information System On Civil Aircraft

To most of domestic airlines,the maintainance engineering is concerned to their survivals and development . For long times ,most of the airlines are still in the primitive stage of manual management on maintenance information.Especially in the work of troubleshooting on the civil aircraft ,there are difficulties of efficient engineering information support in the field of the airport .Therefore, the delays of the flights always happen ,and it cost big loss of money to the airlines.Referring to the newest proposal on aircraft maintenance of the military of U.S.A and aimming at the problems of the information management system of traditional civil aviation maintainence engineering, this thesis came up with a new system - digital integrated maintenance and support information system (DIMSIS), which is made up by the technologies of computer network, database, communication engineering, software engineering and etc.After its building,most of the requirements of the domestic airlines on information technologies will be met.Based on the case of the practice in China Eastern Airlines Wuhan Limited, this thesis firstly studied several layers application model on Intranet of enterprises development. In the model of DIMSIS, three layers application model on network was used, including the three layers form of Client/Server constructure ;then the access technology of database on Intranet network was analyzed; meanwhile, the proxy server technology with the security technology of the networks was studied.Following these items , the technology of Wireless Local Area Network was put forward and the possibility of it was discussed. At the end of this thesis the information management system of spares of civil aviation based on SQL server ,Active X and ASP technology was developed.
