A Reconfiguration Method of Spaceborne Control Computer

Abstract

The invention relates to a reconfiguration method of a spaceborne control computer. The steps of the method include: (1), system division of the FPGA of the computer unit; (2), the FPGA configuration file of the computer unit of the ground control center; (3) , the ground control center sends the FPGA configuration file to the number management subsystem; (4), the number management subsystem sends the FPGA configuration file to the whole star bus; (5), the computer unit resets the The method adopts SRAM type FPGA to replace the central processing unit of the original on-board computer, and designs the reconfiguration control circuit and reconfiguration configuration data memory on the original on-board computer to connect with the configuration interface of the SRAM-type FPGA. The FPGA is divided into a reconfigurable area and a fixed area, which can realize the on-orbit reconfiguration of the on-orbit control computer, so that the on-orbit computer can use the uplink injected configuration file to change the function in real time under the control of the ground.

Description

technical field [0001] The invention belongs to the field of on-board computer technology, in particular to a reconfiguration method for an on-board control computer. Background technique [0002] Once the existing spaceborne computer is designed, its hardware interface and functions cannot be changed. It lacks flexibility in the face of complex space environments, and cannot change its own functions to adapt to the changing space ring through autonomous or ground intervention. Future long-term and long-distance space activities, especially the needs of autonomous flight control of spacecraft. [0003] At present, the on-board computer of the new generation of spacecraft has an increasingly urgent demand for variable structure and variable function, and there is an urgent need for an on-board computer that can realize real-time function reconfiguration on-orbit. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the ...
