Abstract: A method and system for virtually coupled train set (VCTS) control is provided. The method includes following steps: determining whether to execute a backup control strategy based on an actual state for a current cycle of each train unit and a target state sequence for a first preset number of cycles before the current cycle to obtain a first determination result; if the first determination result is yes, executing the backup control strategy to control each train unit; if the first determination result is no, calculating the target state sequence for the current cycle of each train unit according to a position or calculating the target state sequence for the current cycle of each train unit by using a synchronization relationship; and controlling each train unit according to the target state sequence for the current cycle of each train unit, respectively.

Abstract: Disclosed are a cloud safety computing method, a device and a storage medium based on cloud fault-tolerant technology. The cloud safety computing method includes following steps: S1, adopting a one-master multiple-slave fault-tolerant architecture for management nodes, and using KeepAlived and Haproxy to realize a liveness self-check of the management nodes and a load balancing of user requests, and S2, adopting a dynamic redundancy fault-tolerant safety design for service nodes to maintain a life cycle of application microservices, and giving feedback on liveness information to the management nodes in real time through heartbeat by the service nodes, where the application microservices report the life cycle to the management nodes based on a probe mechanism, and the application microservices exchange input and output information through redundancy voting.

Abstract: Embodiments of the present invention provide a train control method for maximizing utilization of regenerative energy. The method mainly comprises: working out a matching error ΔT of a current matched pair of trains Mx (i, j) of a station in the current running situation; and comparing the matching error ΔT with a preset maximum adjustable error ΔTx of the current matched pair of trains Mx (i, j) of the station and determining a strategy for adjusting train running of the current matched pair of trains Mx (i, j) according to comparison results.
