Design And Implementation Of Integrated Equipment For Platform Management System And Research On Fault Location Technology

With the development of science and technology,the status of the aircraft is more and more important in modern war,and the aircraft platform management subsystem as the core module of the aircraft control system,it shows better advantages.What's more,it is very important to develop a more generalized flexible test equipment with the aircraft platform management module as the measured object.Due to the traditional test equipment is a special equipment designed for a certain equipment,it can't meet the needs of modernization.Based on the aircraft platform management sub-system integration of integrated equipment of the actual project development the hardware equipment,Our group designed a set of imploded integrated equipment,to meet the needs of modern automated test software,and the design of the software module is main researched in this thesis.The device can test all-round test of the object,and test the signal interface types are: RS422 signal,analog signals,resistance signals and so on.And we further study the fault location technology to facilitate the latter part of the operator to provide some maintenance recommendations.In this thesis,we use software to correction the analog data of Collected.Through the comparison of several correction schemes,the linear regression equation is chosen to correct the accuracy error,then to study the auxiliary location of fault diagnosis.And through modeling and simulation and comprehensive analysis,a prototype scheme suitable for the prototype of the current test equipment is proposed,but the fault diagnosis module is implemented later.Through the analysis of the functional requirements and performance requirements of the equipment,the software is designed with the frame module of the classical framework MVC(Model View control).The MVC framework is used to separate the data and operation of the device software,and each function does not affect each other,to achieve the characteristics of high cohesion and low coupling.At the same time,the modularity of the software can be used to realize the new function according to the change of the demand,and the modules can be re-combined with stronger adaptability and refactoring.The design of the signal parameters in the documents uses the INI files and ATML(Automatically Test Markup Language)descriptive language file storage,and can make the software adapt for other devices or meet the new needs by modifying these storage files,ensuring the system has a stronger versatility.Finally,the test results show that the upper and lower computer software is able to meet the needs of the project at this stage with its good running,perfect function and superior performance.In addition,the software has a strong portability which provides a reference for other software design.
