基于水声潜标应用的数据采集及大容量存储系统设计

Design of data-sampling and high-capacity storage system in acoustic submersible buoy application

水声潜标是获取海洋水声信号以及海洋生物声信号的重要技术设备之一。为了满足水声潜标在水下较长时间工作,本文设计并实现了一套基于水声潜标应用的低功耗数据采集及大容量存储系统,在芯片选型和NAND FLASH读写管理等方面对系统进行了低功耗设计。该系统在"标-矢量"综合潜标上应用的试验结果表明,该系统获取的数据有效,满足总体设计技术要求。同时,本系统还具有良好的扩展能力,可适应水声潜标发展的应用需求。

The acoustic submersible buoy is the one of the important measurement equipments for ocean acoustic signal and marine acoustic signal. In order to meet the application requirements of acoustic submersible buoy for long time working, this paper designed and realized a data-sampling and high-capacity storage system. The low-power measures for the system included the choice of CMOS chip and read-write management for NAND-Flash. We applied the system to the comprehensive acoustic submersible buoy with scalar hydrophone and vector hydrophone, and the experimental data demonstrated that data acquiring was reliable and effective and it met the overall design requirements. The system has good scalability and meets the future needs of the submersible buoy.
