现代线列阵声纳的规模越来越大,对数据传输系统的要求越来越高,千兆以太网具有通信速率高、传输距离远、工作可靠性高等优点,且支持全双工模式。本文将千兆以太网高速数据传输技术应用到线列阵声纳设计中,以实现采集数据的实时传输,并针对传统单向级联转发方案中一旦有节点发生故障,后续所有传输数据都会中断的问题,提出了一种双向环路冗余组网方案,赋予传输系统一定的容错性能,以提高系统的工作可靠性。文中从传输控制模块软、硬件实现以及多传输控制模块双向环路冗余组网方案等方面对传输系统进行了介绍。
Modern linear array sonar is more and more large, and its requirements on data transmission systems are getting higher and higher. Gigabit Ethernet has the advantages of high communication speed, long transmission distance and high working reliability, and supports full-duplex mode. In this paper, the application of Gigabit Ethernet high-speed data transmission technology to the linear array sonar design, in order to achieve real-time transmission of collected data, and for the traditional unidirectional cascade forwarding program in the event of a node failure, subsequent transmission of all data will be interrupted A bidirectional loop redundancy networking scheme is proposed, which gives the transmission system a certain degree of fault tolerance in order to improve the reliability of the system. In this paper, the transmission system is introduced from the transmission control module software and hardware implementation and multi-transmission control module bidirectional loop redundancy networking scheme.
