Development And Research Of Management System For General Aviation Maintenance Technical Information

With the rapid development of information technology and the furious marketcompetition, the domestic and international airlines are promoting the construction of theinformatization management system for the maintenance technical information. While for thegeneral aviation, information management still remains in the manual paper-based operations,and lack effective measures to deal with aircraft maintenance information. Therefore, the lagand deficiency of the information management has hampered the development of the generalaviation units.Referring to the newest proposal on maintenance information management systemtechnology of the domestic airlines, aiming at the status of the maintenance technicalinformation management for the general aviation units, as well as the shortcomings, thisthesis proposes the establishment of the informatazation management system for themaintenance technical information. This thesis chooses Delphi as the platform to designinformation management system, takes three-tier C/S structure development model, builds upanalysis model and design model under the object-oriented ideas, designs the system functionmodules and database by these models, builds the system database using Microsoft Access,uses the ADO and MIDAS to realizes the access to the database and the connection betweenthe database and application servers, uses fault diagnosis based on fault tree analysis ofinteractive failure to do the diagnosis guide ; Finally, do the program, completes thedevelopment and software test, and analysis of the system deficiencies and improvements.This system implements seven major functional modules: system management, fleetinformation management, airworthiness data management, major maintenance recordsmanagement, fault information management, the LLP management, aircraft statusmanagement. Through these modules , it can collect, summarize, count, analyze and interactall the maintenance technical information, which realizes the real-time information sharing; ittakes full advantage of historical fault data and airplane maintenance manual to complete faultdiagnosis based on fault tree analysis, which provides more scientific and reasonable faultdiagnosis for aircraft maintenance; it also achieves the early warning function of the LLP lifeand aircraft utilization status monitoring. The development and use of it makes a certaincontribution for the informatization construction of aircraft maintenance management system.
