Research On Intelligent Virtual Aero Engine Manual And Work Card Based On Augment Reality

Aircraft engines are large,complex electromechanical systems that require advanced technical skills to maintain.Their internal structures are intricate,and maintenance and repair are difficult and expensive.The quality of engine maintenance directly affects its performance and reliability.Currently,engine maintenance is mainly done by referring to paper documents or electronic manuals,and operators have to sign their names and record the date on a work card after completing each repair step,resulting in low efficiency and increased risk of errors.Moreover,the quality of maintenance assembly relies heavily on the skills and experience of maintenance personnel,which may lead to poor quality control.To solve these problems,a user-centered,intelligent maintenance assembly guide book and manual are urgently needed to help operators complete complex maintenance assembly work more efficiently and reduce errors.To achieve this goal,augmented reality technology can be used to supplement virtual information with real-world information.This thesis explores the human-computer interaction design of augmented reality in the field of civil aviation engine maintenance,enabling maintenance personnel to access work cards and manuals in a more convenient way,obtain necessary information during the maintenance process,improve the efficiency of civil aviation engine maintenance personnel and reduce the cost of aircraft maintenance.In addition,a new way of signing work cards based on voiceprint recognition technology is developed to free the hands of maintenance workers.After comparing various devices,this project uses Microsoft’s Hololens 2 as the development platform and the development solution provided by Microsoft.Since the entire project adopts the C/S project architecture,this thesis presents the engineering environment deployment of the client and server,the design pattern and program design details of the client system,and the development of the voiceprint recognition model and network connection on the server side in order of client-server.
