中文摘要随着海洋资源开发和国防技术的日益发展,水下网络技术成为近年来许多民用领域及海军军事研究领域的一个热点。水下网络技术主要通过声传播来实现节点间的通信功能,多个节点按照一定的拓扑结构和网络通信与控制协议组成网络,可提供水下指挥、控制、通信和导航等功能,通信节点配上探测传感器,结合信息融合技术,还能够实现对水下目标、海洋环境的定位、跟踪和探测。本论文研究的内容是水下网络节点的信号处理系统的设计。信号处理模块是网络节点的核心部分,关系到整个系统性能的好坏,是系统的灵魂。针对水下网络信号处理系统的特点,在借鉴、发展和创新的基础一匕本论文设计并实现了一个低功耗、高速信号处理系统。该方案结合小型化、实时性要求,采用当前先进、成熟的BlackFin数字信号处理芯片和CPLD技术,具有结构简单、低功耗、模块化、可重构的特点。系统经过调试、测试,工作稳定可靠,完全满足网络节点信号处理和低功耗等各项要求,并且能够作为多种水下设备信号处理平台。
英文摘要In recent years, underwater network technology has received much attention in civilian domain and National Defence. Underwater network technology implements the communication of nodes by sound transmission, which makes use of node system to build up network according to certain topology and communication protocol. It is a system which can provide functions of command > controK communication and navigation. Equiped with sensor and combined with information syncretize technology, it can also orient scout and explore the underwater target and environment. This thesis emphasizes on the design of signal processing system of network nodes. The signal processing module is the kernel part of the node, which decides the performance of the whole system. Aimed at the characteristic of signal processing system of underwater network, this thesis brings forward a design project and implements a low power > high speed signal processing system. Based on the demand of miniature and real-time, the design makes use of advanced and mature technology in BlackFin DSP chip and CPLD to build up the whole system in briefness ^ modular and re-configurable form. The system was validated to be a steady and credible digital signal processing platform by debugging and testing, which completely met the commands of low power and signal processing function of network node. The system can use to be a signal processing platform of many underwater equipments.
