Design And Implementation Of Aerospacecraft Practical Tests Data Management System Based On S2SH

With the higher frequency of the physical tests of the aerospace crafts and the increased amount of test data in the development process, the traditional manual data management and the data analysis through programming cannot satisfy the requirements development intensive model process. In this context, through the development of the vehicle test data management system project, this article deeply studied on the test data management system, lightweight J2EE framework and specific technology, and realized the system requirements.Firstly, in this paper the current situation of space vehicle test data processing background is analyzed in the whole background of the vehicle physical test and the data processing. According to the comparison of the home and abroad existing test data management system, puts forward the design of the B/S structure system to meet the requirements of the large amount of users and processing, the complexity of business functions, large scale of software system. Selecting the J2EE platform development standards for the B/S structure system to ensure that the system framework of stability, openness and security, this paper uses a lightweight J2EE technology, and chooses maturity framework Struts2, Spring, Hibernate. Then this paper researched on these three frameworks, and integrated them.On this basis, the use of the high openness framework, and the integration of the jBPM framework and Spring Security framework, can enhance the ability of transaction in the business logic layer by using the IoC(Inverse of Control) and AOP(Aspect Orient Programming) technology to achieve workflow management and authority safety management. The integrated framework uses Spring framework as core, agents the action of Struts2 by using inversion of control, provides the agency to Hibernate support class, realizes the integration of the S2SH application, and integrates the middleware management framework. In this paper the integration and the achievement of S2SH and management framework was proposed. In the J2EE standard on the basis of layered, it is not only realized the decoupling between each layer, and extracted affairs logic function in the logic layer, but also enhanced the business logic layer. Finally, the system realized parameters processing, reading, pretreatment, calculation, analysis, statistical analysis, image post-processing, comprehensive analysis of complex process and rights management.Finally, in this system, according to the problems of mass data accessing and multi-client concurrency, performance problem analysis has been done. Through the analysis of the test result, it has been verified that system function and performance meet the design requirements.
