The Design And Realizaion Of The Aircraft Time-Limiting Detecting System

To most of domestic airline armies, the maintenance engineering is concerned to their survivals and development. For a long time, most of the airlines are still in the primitive stage of manual management on maintenance information, which is in low efficiency and high cost. The share of resource such as maintenance information, airline materials, equipments and maitenance experience is not well realized in airline armies and between other maitenance departments. Also, there is not a good information management system to manage information resource. At the same time, there exists the contradiction between great information demand and low efficiency in the work of troubleshooting in the front line of parking apron. Therefore, the delays of the flights always happen ,and the whole battle effectiveness goes down.Referring to the newest proposal on aircraft digital maintenance technology of the military of U.S.A , aimming at the problems of the information management system of traditional civil aviation maintainence engineering, and integrating the real demand and practice of some Chinese aviation corps, this thesis come up with a new system— aircraft time-limiting detecting system. This system is made up by the technologies of computer network, database, communication engineering, software engineering and etc. First of all, it establishes a intreior military LAN with Internet/Intranet technology, then it inputs the primitive information—maitenace notebook into the host computer system to achieve the fast information access in every terminal. What's more, aiming at the strict requirement of life-limiting components in avions, it especially develops corresponding information inquirement and tracking system functiuon to improve the control of using life of life-limiting components and the speed of failure elimination. At last, based on this, it develops a comprehensive information management system of maitenance departments' units to supply information for maitenace and decision-making.This thesis analyses the information status of our country's aviation armies, abstracts the dialy maintenace flow of avions and elicits the material user demand analysis. It discusses the IMIS( Integrated Maintenace Information System) development in Chia and brings forword the factors to restrict its development and replying measures. According to the fact of our aviation armies, it develops the basic function system of IMIS— airlane time-limiting detecting system, which is the expanding flat of IMIS. It reserches the application of three layers C/S system stucture in military information system based on Internet/Intranet, builds up system and database model under the object-oriented idea, designs relevant database by these models, and developes the system with Vissual C++ and SQL Server2000.
