Abstract

The invention provides a space information system based on a SpaceVPX standard, which comprises an information plane, a system management module, a main control module, an exchange module and a function module which are in communication connection with one another, and is characterized in that the information plane is used for providing different data exchange topology networks according to the data transmission rate among internal modules of the system; the system management module is used for providing a management strategy of each module in the system and a communication protocol among themodules; the main control module is used for limiting and controlling each module to execute a corresponding task; the exchange module is used for limiting an interaction relationship among the modules; and the function modules are used for limiting the functions of all the modules. Therefore, the spatial information system aiming at the SpaceVPX standard can be constructed, so that the whole system is more standardized, and the applicability is wider.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a space information system based on the SpaceVPX standard. Background technique [0002] The space information system is a space electronic platform integrating platform management, data storage, information processing and other functions. Improving the performance and reliability of the space information system and promoting the modularization of the space information system are current research hotspots. Among the currently known VPX information system platforms, the platform designs are ground applications based on OpenVPX, such as patents CN205389239U, CN105488566A, CN104243174A, etc; In the functional design of the whole machine. [0003] However, the above patents are all proposed based on the VITA65 (OpenVPX) or VITA46 standard, which lacks reliability design for aerospace applications, making the entire system not standardized enough and poor in applicability. Conte...
