摘要
分析了CAN-BUS作为主流现场总线的重要作用和技术特点,讨论了CAN-BUS应用在电动汽车上的巨大潜力和发展前景.研究了CAN总线的4种主要拓扑结构,通过分析CAN的协议标准,定义了电动汽车上光纤通信的协议规则,设计了一种适合于电动汽车的CAN总线节点,同时提出了一种基于光纤材料的双环CAN网的结构模型及实现方案.实验证明,该方案在电动汽车总线控制及信息传输等方面有一定的应用价值.
The importance and characteristics of CAN-BUS which serves as the mainstream field bus was analyzed. The potentiality and development prospect for CAN-BUS to be applied in electric vehicle was discussed. The four Topo-structure of CAN-BUS was studied. Through analyzing the protocol standard of CAN, a agreement rule of fiber optic communication used in electric vehicle was defined, and a CAN-BUS node suitable for electric vehicle was designed. Meanwhile, both structural model and realizing scheme of the double-chain CAN network based on optical fiber were proposed. The experiment proves that the scheme is valuable for electric vehicle control and information transmission.
