Abstract

An active fault-tolerating method of software based on chain list includes using application software to realize all function, dividing application software to be multiple function module as each module containing a master algorithm and N numbers of backup algorithms, using fault-tolerant software to monitor operation of each function module and revising module relation chain list to start up relevant backup algorithm for tolerating error by fault-tolerant software when master algorithm of certain function module is on error as well as shielding off said function module by fault-tolerant software when N numbers of backup algorithms are all on error.

Description

technical field

[0001] The invention relates to a software active fault-tolerant method, in particular to a software active fault-tolerant method based on a link table, which adopts a software active fault-tolerant design method for a lunar surface inspection detector based on a link table. Background technique

[0002] Software fault tolerance is the ability of software to detect software or hardware faults that will occur or have occurred in the system and recover from the faults. It has two meanings: one is to use software to achieve the purpose of fault tolerance, and the other is to allow software faults by the software itself . The main purpose is to provide sufficient redundant information and algorithm programs, so that the system can detect programming errors in time during actual operation, and take remedial measures to improve software reliability and ensure the normal operation of the entire computer system. There are generally two strategies for fault recovery:...
