Research On Software Object Framework Of Tracking & Telemetry Real Time Data Processing

Real-time data processing software is the key part of the Tracking and telemetry command system(TTC), which collects, processes and records the data. Developed in a short time and used for a long time, it is really a hard job to maintain the special software for the changing staff.Nowadays the TTC real time softwares are always using the structured processing pattern based on the special hardware platform, which puts the emphasis on the data processing algorithms and lacks in the detailed research on the software architecture. Therefore, the software and hardware interacting each other, and the modules are coupled tightly and can be reused little. A good pattern can instruct software design and lead to high quality.With the rapid development of computer technology, Object-oriented analysis and design become the popular way in applications. Though there are a lot to do for the special software to use the OO theory, it is practical to design an object-oriented common software framework based on the analysis of the real time data processing and the TTC devices for the needs of high quality TTC missions which are more and more frequent.Real-time data processing software is becoming the key part of the control system, for the needs of the higher precise control , the software is becoming more and more complex. However the software based on this framework has such characteristics as common to use, easy to maintain and more expandable. The framework defines the pattern of the software's component, function and schedule, which can reduce the fee and develop period by fulfilling the particular interfaces according to the peculiar requirements of the real time software.Based on the analysis and research above, we designed a pattern—the framework of the realtime TTC data processing software, which has been used in the missile launching.
