Reconfigurable triple-redundancy computer system and configuration degradation method thereof

Abstract

The invention provides a reconfigurable triple-redundancy computer system and a configuration degradation method thereof and belongs to the field of computers. After a triple-redundancy control computer system is power on, the system works in a hot standby redundancy manner; when any control computer goes wrong, the faulting computer is reset or power off, recoverable faults of one computer are eliminated; the restarted faulting computer acquires current working state information of the other two computers to complete reconfiguration; when multiple faults occur in one computer, a power failure operation is carried out on the computer; the remaining two computers at normal operation run in master-slave working modes of the two computers; when a host of the two computers goes wrong, the standby computer seizes the right of communication for an external interface and works in a standalone mode. Rapid data interaction is carried out on each control computer by use of three parallel storage data buffer areas, and the faulting computer and the working computer are reliably determined by use of two judgment methods. The computer logic is simple to realize, all primary faults and part of secondary faults of the computers can be solved, the reliability of the computer system is improved and an engineering application is facilitated.

Description

technical field [0001] The invention relates to a reconfigurable triple-redundant computer system and its reconfiguration and degradation method, especially a long-time, highly reliable, and fully autonomous computer fault diagnosis and decision-making method in the control system of launch vehicles and spacecraft, which belongs to computer technology field. Background technique [0002] Due to the unique advantages of the triple-redundant computer, various types of upper stages, quick-response liquid small rockets, solid small vehicles, air-launched small vehicles, and heavy-duty launch vehicles for manned lunar exploration will have a wide range of applications in the future. application. [0003] With the development of my country's space applications, scientific exploration, and manned spaceflight, and the deepening of international commercial launches and international cooperation, there are more and more launch missions for launch vehicles, and high-density and rapid ...

AI Technical Summary

Problems solved by technology

[0004] There are many models of computers with triple-redundancy architecture used in launch vehicles and spacecraft, and generally adopt single-point voting, single-point interface or multiple redundancy schemes, which cannot achieve a balance between redundancy and economy, and cannot adapt to long-term Aerospace computer applications
