Abstract :
The fault-tolerance of multi-sensor system is analyzed in this paper. Based on studying the existing methods, the information sharing coefficient method based on the expert system is proposed. The theoretical analysis and simulation show that this method can effectively improve the fault-tolerant performance of the fault-free subsystem and reduce the computation load of the whole system.
