CAN总线通信在全电子计算机联锁系统中的应用

Application of CAN Bus Communication in Full Electronic Computer Interlocking System

CAN总线通信在铁路信号相关系统中被普遍采用,但受通信节点数量和通信速率限制,其应用受到一定限制。在全电子计算机联锁系统设计中,采用二级CAN总线架构模式和排队机制,实现CAN总线在多节点、实时性应用条件下的稳定通信,并在冗余线路的基础上,实现高可靠性的数据通信。

CAN bus is widely used in railway signal-related systems, but its applications are restricted by the limitation of the maximum number of communication nodes and communication rate. In the design of the full electronic computer interlocking system, the stability of CAN bus communication in multinode and real-time application condition is realized by two-level CAN bus architecture model and queuing mechanism, and the high reliability of data communication based on the redundant lines is also realized.
