Study on Reliability and Safety of Automatic Speed Control System Based on Dual Redundant Model
In order to guarantee the safe operation of train and improve the operation efficiency, a kind of failure-safety control strategy of system is proposed based on the dual-redundant control mechanism. The paper analyzes the function requirement of train automatic speed control, researches on the design principles and methods of the architecture design of the dual-redundant control system which is based on the tolerance theory, analyzes the control strategy of the system running state translation, uses Markov model to analyze the system reliability and safety. Finally, a series of simulation analysis are performed, and the results show that the system has good reliability.
