中文摘要：

随着互联网技术的不断发展，TCP／IP网络协议的应用日益广泛。水声信道的相关研究往往需要应用多个浮标设备，因而对浮标设备的网络化要求逐步提高。以往的只具备无线通信而无网络协议的浮标系统已不能满足新研究的要求。本文应用微控制器MSP430、网络协议栈芯片W3100A及无线网桥，设计并实现了基于TCP／IP的浮标通讯系统，给出了硬件及软件设计说明。该系统尝试了TCP／IP网络协议在水声信道研究系统中的应用，以较小的软件开销实现了高效率的网络连接，大大提高了水声信道测量平台的网络化水平。

英文摘要：

TCP/IP network protocol has been applied in many fields with the improvement of Internet technology. Many buoy equipments are adopted in the research on the underwater acoustics channel, and their abilities of network become more and more important. Buoys with wireless communication but without network protocol cannot meet the requirement of new research any more. A communication system based on TCP/IP is designed by using of the microcontroller MSP430, hardware protocol stack W3100A and Wireless Bridge. And the designs of both the hardware and software are presented. The system applies the TCP/IP network protocol in the research system on channel of underwater acoustics and realizes efficient network connection while saving the software cost, which enhances the ability of surveying platform of underwater acoustics channel.
