Redundant optimization design of train central control unit based on auxiliary arbitration
Based on the design and development of a new type of train control and monitoring system,a redundant optimization design scheme for the central control unit of a train control and monitoring system built on a single vehicle bus is proposed.Through third-party reliable network access equipment,the auxiliary arbitration of the system control rights of two redundant central control units are conducted to deal with various faults that cannot be solved by independent arbitration.At the same time,from the perspective of improving train operation safety,the actual action mechanism and effect of this method in dealing with bus and equipment failures are expounded.After practical verification,this method can effectively improve the efficiency and accuracy of redundant switching while ensuring the stability of control and monitoring system operation.
