Abstract

Computer system is the basis of aerospace space safety. This paper proposes a three-mode redundancy computer system, which performs real-time triple modular redundancy for work tasks to improve system reliability. The three-computer fault-tolerant system includes processor management software and voting software, and realizes the three-computer architecture through three sets of independent hardware environments. In order to meet the requirements of aerospace, this paper compares the three-computer fault-tolerant system with the traditional dual-computer system on the satellite, and designs the system from the aspects of system architecture analysis, voting process design, redundancy and reliability prediction.
