摘要

为了给被动声探测技术研究提供实验验证平台

设计了一种可以进行实时数据采集和处理的系统方案。整个系统以数字信号处理器（DSP）和现场可编程门阵列（FPGA）为基本架构

由FPGA控制模数转换器（ADC）采集数据

通过USB 2.0电路将数据传送给个人计算机（PC）

用于初期的离线验证;FPGA将采集到的数据通过外部存储器接口（EMIF）传递给DSP

用于实时处理。实验证明:系统实现了被动声探测中的实时数据采集、离线数据存储。数据采集与数据处理分别由不同处理器执行

提高了系统的响应速度与处理性能

能够满足探测系统的实时性要求。

Abstract

In order to provide experimental verification platform for passive acoustic detection technology research

a system scheme for real-time data acquisition and processing is designed. The system is based on digital signal processor（ DSP） and field programmable gate array（ FPGA）. FPGA controls the anolog digital converter（ ADC） collecting data and transferring data to PC through USB 2. 0 circuit for early off-line verification; FPGA transfers the collected data to DSP though external memory interface（ EMIF） for real-time processing. Experiment shows that the system realizes the real-time data acquisition

off-line data storage in the passive acoustic detection system. The data acquisition and data processing are carried out by different processors which can improve response speed and processing performance of the system and satisfy the real-time requirement of the system.
