中文摘要	随着安静型潜艇的出现，拖曳式线列阵声纳以其远离本舰噪声的优点被广泛应用于水面舰艇和潜艇。多通道数据的有效实时传输是数字式拖线阵设计的关键技术之一。在我们设计的新型拖线阵声纳数据传输系统中采用CYPRESS公司的串行背板技术作为湿端的编码电路，因此串行模块与信号处理机之间的数据转换电路成为该拖线阵数据传输系统的重要部分，实现一种实时性强，接口灵活、便于升级的数据转换系统在实际应用中有着重要意义。本论文的工作是设计并实现一个将串行水声信号纳入快速以太网的通信系统，其设计目标是采用商业可利用技术（COTS）为拖曳线列阵提供一个开放的标准接口。在系统设计中采用全双工交换式以太网技术解决传输中通信的实时性和确定性问题，使用UDP通信协议保证传输的有效载荷，避免不必要的填充域数据在网络上传输所占用的带宽，采用总线接口连接串行背板模块和微处理器，进一步保证了网络传输的实时性。根据实际要求，采用SAMSUNG公司的低功耗、高性能微处理器53C4510B作为系统核心，它内部集成了多种片上外设，对简化系统设计和提高可靠性有很大的意义。本文总结了作者在数字式拖线阵声纳数据传输的以太网通信系统设计和实现过程中所完成的具体工作。
英文摘要	With succeeding in development of resting submarine, trailing linear array sonar is especially favored and extensively used for submarine and naval vessel. Real-time and efficient multi-channel data transfer is the key technique for design of digital trailing array. Serial back-board, developed by CYPRESS Company, is adopted for the code circuit of green end in our new-type digital sonar transfer system of trailing linear array. The circuit for data format conversion between the serial module and the signal processor becomes one of the most important elements in the system. It weighs heavily with practical application to implement a kind of data format conversion system that owns the properties of good real-time communication, flexibility and upgrading ease. In this dissertation, the communication subsystem that can put the serial hydroacoustic signal into Ethernet communication system has been designed and implemented. The design objective is to provide an open standard interface for trailing linear array by using COTS. Full-duplex switched Ethernet technique is used to solve the problem of communication real-time property and that of determinacy. UDP transport protocols ensure actual load and prevent unnecessary fill domain data from occupying the costful network bandwidth. The connection point between the backboard module and micro-processer is bus interface, which guarantees the real-time properties further. According to actual requirements, the microprocessor S3C4510B, which is a low-power, high-performance and developed by SAMSUNG Company, is used as system core. Many on-chip peripheral equipments are integrated in this microprocessor, whose characteristic is very useful to simplify system design In brief, my detailed research on design and implementation of the Ethernet communication system for digital trailing sonar data transfer is summarized in this dissertation.
