基于DSP技术的船舶数据采集系统设计

Design of ship data acquisition system based on DSP technology

设计多通道的船舶数据采集系统,提高船舶数据的实时采集和信息处理能力,提出基于DSP技术的船舶数据采集系统设计方案。数据采集系统采用声呐传感器进行船舶的声信息、振动数据以及混响数据采集,采用TMS320C50 DSP芯片作为船舶数据采集系统的核心处理芯片,数据采集系统包括传感器模块、滤波模块、信号检波模块以及PCI总线传输模块,在集成开发环境下进行船舶数据采集系统的硬件模块化设计。最后进行系统测试,本文设计的数据采集系统的增益放大倍数为12 d B,数据采集的时钟频率为33 MHz,总线传输速率可达到264 MB/s,性能指标表现优越。

The design of multi-channel data acquisition system,improve the real-time data acquisition and information processing ability,puts forward the design scheme of ship data acquisition system based on DSP technology,sound information data acquisition system using sonar sensors of the ship,the vibration data and reverberation data acquisition,using TMS320C50 DSP chip as the core processing chip of ship data data acquisition system,data acquisition system includes sensor module,filter module,signal detection module and PCI bus transmission module,hardware module design of ship data collecting system in the integrated development environment.The system test data acquisition system designed in this paper the gain amplification ratio is 12 d B,the clock frequency for data acquisition 33 MHz bus transmission speed can reach264 MB/s,performance index of superior performance.
