摘　　要：以智能传感器网络为背景,在CAN V2.0技术规范的基础之上提出了基于CAN总线的智能传感器网络的应用层通信协议。首先根据传感器之间相互独立,数据传输量小的特点设计了一种扩展帧的数据传输格式。设计了方便快捷的设备管理机制、数据收发机制及测试界面,实现了智能传感器网络的数据传输,解决了针对智能传感器网络数据交互的问题。最后利用协议分析仪CANalyst-Ⅱ进行了实验测试,验证了协议的有效性。This paper proposed a CAN- BUS protocol of application layer based on CAN specification 2. 0 with the background of intel- ligent sensor networks. According to the independence of sensor and the small amount of data transmission between the sensor nodes, this paper has designed a data format for an extension the frame. Based on the structure,this paper has designed a convenient device management mechanisms,data transceiver mechanisms and test interface. It solves the problem for intelligent sensor network data in- teraction. Finally,experimental testing verified the validity of the protocol depending on protocol analyzer CANalyst- Ⅱ.
