基于FPGA的水声信号高速采集存储系统设计

Design of underwater acoustic signals high speed acquisition and storage system based on FPGA

介绍了一种基于FPGA的水声信号数据采集与存储系统的设计与实现,给出了系统的总体方案,并对各部分硬件和软件的设计进行了详细描述。系统以FPGA作为数据的控制处理核心,以存储容量达2 GB的大容量NAND型Flash作为存储介质。该系统主要由数据采集模块、数据存储模块和RS-232串行通信模块组成,具有稳定可靠、体积小、功耗低、存储容量大等特点,实验证明该系统满足设计要求。

The design and implementation of underwater acoustic signals data acquisition and storage system based on FPGA is introduced in this paper. It describes the overall design, hardware design and software design of the system. The control and processing core of the data is FPGA, and NAND Flash is the storage medium whose storage capacity can reach 2GB. The system is consisted of data acquisition module, data slorage module and RS232 serial communication module. The system is reliable and stable, small, and has low consumption and large capacity. The experiment shows that the performance of the system can meet the design requirements.
