CAN总线在三冗余紧急遮断系统中的应用

CAN Bus in Triple Module Redundant Turboset Emergent Trip System

为满足三冗余紧急遮断系统中多点多总线多数据类型的数据传输的需求,基于CAN总线的特点,设计了三冗余系统的通信结构及软件通信流程;提出了CAN协议的报文标识符的分组策略,并解决了多点通信的报文损失问题,应用于三冗余系统中。结果表明,CAN总线提高了三冗余系统的容错性和可靠性。

To satisfy the requirement of data transmiting of muti-node,muti-bus and mutLdatatype in triple module redundant turboset emergent trip system,on the base of characteristics of CAN Bus,designed the communication configuration and software process of triple module redundant system.Proposed group strategy of CAN active＇s message object identifiers,morever,soluted the loss of incoming messages of mutLnode communication and applied in triple module redundant system.The result the use of CAN Bus raises fault tolerant ability and reliability of triple module redundant system.
