摘　　要：综合典型的CAN与TTP总线的应用经验,提出了适用AUV的总线框架以及未来AUV的总线互连、数据传输方法的几点建议,并针对AUV的应用比较分析了基于CAN协议和TTP协议的分布式实时系统的操作原理、可靠性机制、可扩展性、错误处理策略以及系统层面上的一些特性,表明,CAN协议适用于对灵活性要求较高的软实时系统,而TTP协议适用于可靠性要求较高的集成硬实时系统。The applications of typical controlled area network （CAN） protocol and time-triggered protocol （TIP） are summarized to provide a bus framework for autonomous underwater vehicles （AUV） , and some methods are suggested for the bus connection and data transmission of the future AUV. According to the application of AUV, the operational principles, reliability mechanisms, extensibilities, error treating tactics, and the system level properties of the distributed real-time systems based on CAN protocol and TTP are compared. The results show that CAN protocol is well suited for the soft real-time systems where flexibility is important, while TIP is most appropriate for the integrated hard real-time systems with higher reliability requirement.
