【摘要】In order to resolve the problems of system control and information transmission of underwater surveillance system employs a lot of transducer nodes, a two-level bus topology was designed using Ethernet as trunk and CAN-bus (Controller Area Network bus) as branch. The CAN- bus was able to load a lot of transducer nodes that worked autonomously and transmitted information to console through the CAN-Ethernet gateway. A principle prototype was developed according to above ideas, consisting of a console and a gateway and three nodes. The space between nodes was 800m. The distance between gateway and console was 2km. All functions of prototype were implemented, communication speed of CAN bus was up to 50kbps. The applications results indicate that CAN-bus suits underwater surveillance system, and above conceptual design is feasible.%为解决水下监控系统中大量传感器节点的系统控制和信息传输问题,设计构建了以光纤以太网为主干、以CAN(Controller Area Network)总线为分支的两级总线型网络拓扑结构,CAN总线可带载大量自主工作的传感器节点,节点通过CAN-Ethernet网关与岸站之间进行信息传输.根据以上思想开发的原理样机包括岸站设备,1个网关和3个传感器节点,传感器节点间电缆长800 m,网关与岸站之间电缆长2 km,原理样机的各项功能都得到了实现,CAN
总线通信速率可达50 kbps.应用结果表明,CAN总线适合在水下监控系统中应用,上述方案设计切实可行.
