Design of Component Fault Recovery of Integrated Control System Based on Log Information

In view of the limitations of conventional fault recovery design technology applied to the fault recovery of integrated control system components, and for the purpose of improving the software fault tolerance, this paper proposes a design technology of integrated control system component fault recovery based on log information, which uses the log checkpoint information to recover system faulty component using the checkpoint backward recovery technology and the system log information. It relies on the log information to repeat the execution steps since the last checkpoint, so that the process of task execution is exactly the same as that before the fault, which keep the integrity of task execution. The experimental results show that the design technology of component fault recovery based on log information in an integrated control system in a certain field has better fault recovery, it improves system fault tolerance ability.
