Development Of Distributed Dataaggregation System For Creep Testers

Although computer-controlled system for creep testing machine could make automatic controls feasible, the data are still isolated which has become a constraint. In this paper, we do some research on this problem and the proper solutions are outlined.This thesis focuses on analyzing, designing and implementing data aggregation system for creep testers. According to distributed principle, the architecture design, business function design and implementation are introduced sequentially. The main work includes the following:Firstly, through structured system development methodology, the data-flow process is investigated and analyzed, and subsequently the overall functional structure of the system is presented, and the planning principles are established. The principles are practical, open and standardization, scalability, security and reliability, economy.Secondly, with comparative analyzing the J2EE and DotNet, a localized system architecture is proposed.Thirdly, it describes some characteristics and key technology of the system, such as applying authority customization, the pagination transmission of massive data, the authority customization mechanism, applying data patterns in programming.Finally, a summary of the thesis is made and the direction for the future work is put forward.
