Management system for payload information of satellite based on intelligent high-speed router

Abstract

The invention discloses a management system for payload information of a satellite based on an intelligent high-speed router. The management system comprises an intelligent high-speed router, a payload device, a data handling device, a data storage device and a data transmission device, wherein the intelligent high-speed router consists of a SpaceWire routing module, an intelligent control module and a SpaceWire standard bus interface; and the SpaceWire routing module is used for directly exchanging data from the payload device, the data handling device, the data storage device and the data transmission device, or used for outputting the data to a satellite payload low speed bus network by a CAN (Controller Area Network) interface of the intelligent control modular, and used for transmitting a remote control command from the satellite payload low speed bus network received by the intelligent control module to the payload device, the data handling device, the data storage device and the data transmission device. The system solves the problems that currently the interface of a satellite payload system and a data transmission system is complex, rapid assembly and testing are difficult, and the technology upgrade of a device is difficult.

Description

technical field [0001] The invention relates to an on-board payload information management system based on an intelligent high-speed router, in particular to a high-speed and low-speed payload information flow management system based on an intelligent high-speed router for information acquisition satellites, belonging to satellite data transmission and the field of information management. Background technique [0002] In the current small satellite system, the payload system is used to realize the specific space mission of the small satellite in orbit. For information acquisition satellites, the payload generates high-speed data and outputs it to the data transmission system. The data transmission system processes, stores and sends back the raw data of the load to the ground station. In addition, the status monitoring and function maintenance of the payload and data transmission system also requires the exchange of low-speed telemetry and remote control data. [0003] The...
