Flight Data Centralized Processing Software Design Base On The B/S Structure

Rapid growth of aeronautic technique brings higher demand to storage, sharingand processing of flight test data. The storage, management and processing of highcapacity (above30G) of test data is a big problem faced in the specialized field offlight test and data processing. Development of flight test data processing systembased on B/S configuration to process high capacity of test data intensively and toachieve a networking, standard and centralized processing is an effective way toresolve it.In this paper the development profit of flight test data processing systemsoftware based on B/S configuration is systematically concluded and summarized.The major development work of this system including: application of largeinterrelated database ORACLE and building of flight test database directed towards tothe character of data including huge quantity of information, multiform and longperiod; a information-based platform for centralized data processing based on B/Sconfiguration was designed and developed by studying the centralization of hugecapacity of data storage, sharing and processing; critical technique such as building offlight test database under the system platform, centralized processing of data of hugecapacity, multi-task concurrent and loading balance, study of middleware andinformation communication inter network etc. were also studied and discussedthoroughly.Problem faced by the storage, management and processing repeatedly of hugecapacity of flight test data was resolved effectively because of development of thissystem. Application in airworthiness certification flight test of ARJ21-700airplaneand identification flight test of multi types of plane indicates that the system databaseis designed reasonably and includes all the information related to the flight data. Theprocess middleware can be managed and maintained conveniently and appliedefficiently. And the computing cluster system of computer sever has fine stability.Development of the centralized process system based on B/S configurationestablished a favorable technique foundation for the subsequent development of dataprocess platform, and gathered valuable experience for the following systemdevelopment.
