Receive And Storage System For Satellite Testing Data

Today, the industry of satellite has been developed fast, and electrical equipments in satellites become more and more complex with extending of satellite's functions. During any phases of satellite production and design, exacting design and platitudinous experiments are needed, because maintaining on the tract of satellite is not executed.Analysis of current satellite testing data is one measure of controlling satellite's running and working states. During the process of satellite test, analysis of current satellite testing data is necessary, but making use of historical testing data sufficiently is important at the same time. To realize current and historical running and working states well and truly, comparison and analysis of historical testing data is indispensable, which also offers reference for holding satellite running and working trend. Receive and storage of satellite testing data provided the foundation for analyzing these data.This paper introduces the summary of satellite test on the base of whole tasks of receive and storage of satellite testing data, and emphasizes the whole system design and the key technology. The designed kernel of this system is modular, and main exploitations of modules are based on the union of C language and characters of UNIX(or LINUX). System combined the technology of multi-thread and network to actualize the intercurrent disposal task and control several (5-10) satellites' testing data. Aiming at the character of satellite testing data, this system united the storage method of disc file and database (narrow) to store testing data, and improve efficiency of disposing data at the timely. And this system is portableIt's a hope to provide other systems which belong to the project of satellite testing data center with support founded on this system, especially supplied data access environment to relative system that distills data. Improving automatic and centrally managed abilities is the aim to this system which can lighten workload of technical employ and reduce the spending of resource of whole project for satellite test on same degree.
