列车网络控制系统中央控制单元数据安全冗余机制

Data Security Redundancy Mechanism of Central Control Unit in Train Network Control System

文章在既有列车网络控制系统中央控制单元冗余机制的基础上,提出了中央控制单元数据安全冗余机制,实现了中央控制单元的快速、稳定、安全地冗余切换,提高了列车网络控制系统的通信抗干扰度,避免了MVB总线出现双主、无主的情况,保障了动车组的网络数据安全。

Based on the existing redundancy mechanism of the central control unit of the train network control system and management system,the data security redundancy mechanism of the central control unit is proposed to realize the fast,stable and safe redundancy switching of the central control unit,improve the communication anti-interference degree of the train control and management system,avoid the dual master and no master of the MVB bus,and ensure the network data security of the EMUs.
