Abstract

The invention provides a spaceborne computer system capable of be assembled on orbit. The system is characterized by comprising a data processing module and a hot plug permanent storage module, and the data processing module and the hot plug permanent storage module are in communication through a CPCI bus; the data processing module is used for state self-inspection and diagnosis, data management and task scheduling control, and management of the CPCI bus as a CPCI bus main control device; the hot plug permanent storage module is used for power management during on-orbit assembly, storage of user image data, and CPCI bus data communication responding to the request of a processor module as a CPCI bus terminal device. The spaceborne computer system capable of be assembled on orbit achieves hot plug operation of an embedded spaceborne computer module and can be used for on-orbit maintenance and service of various spacecrafts in future.

Description

technical field [0001] The invention relates to the technical field of satellite platforms, in particular to an on-orbit-assembled on-board computer system. Background technique [0002] Today, with the continuous development and progress of science and technology, space on-orbit service technology has shown huge advantages and benefits. Europe and the United States and other space powers have realized the necessity of "space on-orbit service" technology, and launched the concept of space on-orbit service , basic scheme, benefit evaluation and research on some key technologies. Space on-orbit service technology can be divided into manned on-orbit service and autonomous on-orbit service according to the type of service body. At present, the key technology of on-orbit service mainly revolves around manned on-orbit service. The astronauts are sent into space to perform service tasks such as assembly, recovery, repair, and release, such as using astronauts to release solar pane...
