Abstract:

Redundant technology mainly uses the method of hot standby to cope with high complexity and large-scale system, but the difficulty is that it cannot accurately position the failure unit. In response to the difficulty, a repair method based on distributed control systems is proposed, which uses the repairable setting to realize fault position. By establishing Markov models and simulation respectively, the reliability and safety of the two schemes are analyzed. The simulation results show that the repairable control method can improve the reliability and safety, the safety and reliability of the system is maximized when the fault detection rate of the redundancy unit is equal to the main unit and the failure rate of the redundancy unit is greater than the main unit.
