摘要
海洋环境噪声既是各种海洋声学系统的背景干扰场,同时也携带着大量的海区信息,因此海洋环境噪声研究具有非常重要的意义。本文主要是基于矢量水听器、DSP(Digital Signal Processor)、CF(Compact Flash)卡、无线网桥和串口设备联网服务器这些硬件条件构建一个海洋环境噪声数字采集系统。
论文首先充分研究了海洋环境噪声采集对系统的性能要求,给出了在海洋这一特殊环境下工作的数据采集系统的总体设计方案。其次,针对能长时间独立工作、可远距离控制与通信以及低功耗等技术指标进行了硬件系统设计;系统选用了TI(Texas Instruments)公司的低功耗的DSP芯片TMS320VC5509A为系统核心工作模块的主处理单元,兼容IDE(IntegratedDrive Electronics)/ATA(Advanced Technology Attachment)协议的CF卡为主存储介质,而高速的无线网桥和串口设备联网服务器是系统通信链路中的核心设备;根据系统要求及选型器件设计绘制了电路原理图并制作了电路板。论文第三章对噪声采集系统的软件进行了设计开发;DSP的软件代码主要包括信号采集(含罗经数据采集)、存储和传输三个部分;采集得到的数据以FAT32(32-Bit File Allocation Table)文件系统格式存储于CF卡上:而传输部分根据多深度测量和海洋工作环境的需要,采用了串行通信加无线网络通信的联合通信方式。
论文最后讨论系统调试中遇到的问题及其相应的解决途径,并结合水池与海上实验对系统的数据采集性能、可靠性进行了现场测试;海上实验证明海洋环境噪声采集系统满足设计需求,可以应用于水声研究和水声工程领域。
Ocean ambient noise (OAN) is not only the background noise of all kinds of underwater acoustic system. But it also carries a lot of information about interesting sea area. So a characteristic analysis of OAN is of great benefit to many aspects. This paper focuses on the development of a OAN acquisition system (OANAS) based on Digital Signal Processor (DSP), Vector hydrophone, Compact Flash (CF) card, wireless bridge and serial devices.
Firstly, a system design scheme of OANAS has been provided based on the operational environment, the function and the demands. Secondly, a hardware system of OANAS is designed according to the demand of long-time operation, remote control and communication, low power consumption. OANAS chooses TI's TMS320VC5509A with low power consumption as CPU. The main storage is CF card, which is compatible with Integrated Drive Electronics (IDE)/ Advanced Technology Attachment (ATA) protocol. Nport 5430 and BreezeNet DS.11 are used for communication. In chapter third, the programs based on DSP are developed. 32-Bit File Allocation Table (FAT32) format file system is used for data storage on the CF card. Serial communication and wireless communication is united for data transmission.
Finally, this paper gives some discussions on some problems occurred in the pool and sea experiment and relevant resolutions. The results from sea experiment show that this OANAS satisfies the demand and can be applied to underwater acoustic research field.
