摘　　要：本文对拖曳式海洋传感器阵列总线进行分析,提出了一种基于RS-485双绞线并具有拓扑结构的海洋传感器阵列总线。新型海洋传感器阵列总线采用多回路拓扑结构来提高系统的冗余性,采用接力式结构使传输速度不受距离限制,克服了传统串行通信总线轮询效率低海洋复杂环境下可靠性不高的缺点。In this paper,we analyze towed ocean sensor array bus,and propose an ocean sensor array bus based on RS-485 twisted-pair topology.Multi-loop topology is adopted in the new ocean sensor array bus to improve the redundancy of the system.And relay structure is adopted to the transmission speed is not limited by distance,it overcomes the disadvantage of low polling efficiency of traditional serial communication bus and low reliability in complex Marine environment.
