Abstract

The invention provides a spaceborne computer operation method and system based on redundancy and degradation, and the method comprises the following steps: a configuration step: employing a plurality of spaceborne computers, and carrying out the configuration of the spaceborne computers; the use steps: when the spaceborne computer fails, performing running operation according to configuration. According to the invention, when the space-borne computer has a fault, the security software is continuously degraded and operated to ensure the normal execution of the basic service of the system and trigger the fault emergency response processing of the whole system; and a partial repairing function is realized.

Description

technical field [0001] The present invention relates to the technical field of on-board computer operation, in particular to a redundancy and degradation-based on-board computer operation method and system. In particular, it preferably relates to a method for continuous autonomous operation of on-board computers based on redundancy and degradation. Background technique [0002] Computer systems in a complex space environment are extremely vulnerable to the threat of solar wind, space electromagnetic storms, space high-energy particles and cosmic rays, and single-event upset failures occur. The embedded software running on it, such as on-board management software and star service software, is the control core of the satellite, which has high requirements for reliability, safety, maintainability and service life, especially in the event of The downgraded operation of the system after a single event failure and the fault tolerance during standby switchover are very demanding. ...
