Research on Bus Fault-Tolerant Mechanism and Its Verification Method
Meng Gao · Aerospace Control and Application · 2010
Fault-tolerant technique is extensively used in the satellite control systems to improve reliability. And the stability and reliability of bus communication are critical for the success of tasks. In real engineering development, the fault-tolerant mechanism is commonly used to identify and to shield the bus communication failures. A fault simulation-based bus fault-tolerance verification method including failure specification analysis technique, fault-case generation technique and fault simulation technique is described in the paper. As an example, the fault-tolerant capability of a satellite software bus is tested using the method, and the validity and practicability of the method are verified.
