Development of Aviation Sealing Standards Management SystemBased on Domain KnowledgeAbstractThis paper proposes the management thought of aviation sealing standards relatedknowledge by analyzing the management of standard parts library and the traditional standarddocuments,for the problems of"inconvenience","use confusion"and"lack of physical model"existing in the traditional management model based on "documents"and "standard partslibrary"to meet standards.It not only manages standard itself and its basic information,but alsomanages its version changes,application attributes and technical relationships.Based on thisidea,the following studies have been carried out under the goal of improving the standardmanagement and the standard application capabilities represented by aviation seal standards.(1)Based on the classification and analysis of aviation seal standards,the paper realizesthe digitization of the standards with domain knowledge related it.(2)A knowledge framework system in aviation sealing and its description model for eachmodule in the framework is established.Using the framework representation represents theknowledge of each module,and the mapping of the description model of the tables in thedatabase is implemented by using database technology,and the data required in the systemdevelopment process are sorted out.(3)Taking Visual studio as a platform and using QT technology,aviation sealing standardquery management system is completed based on domain knowledge.Users can add,view,modify,and delete the knowledge involved in each module of the management system,andsearch basing on multiple conditions or standard numbers (names)to call the standard file andmodel.The paper forms the theory and method that can effectively help Chinese enterprisesimprove the standard management and application level from the digitization of standard andknowledge management level.This cannot only effectively promote the application ability ofthe company's own standards,but also form a method that can be used for promotion andreference for the standards management based on knowledge.Keywords:Standard digitization;Knowledge Framework;Descripting model;Databasetechnology;Qt(Cross-platform C++GUI application development framework)
