摘要

从硬件和软件两个角度出发，介绍基于DSP的多元数据同步采集与存储系统的组成、工作模式以及功能的测试。系统主要由上位机和数字采集与存储单元组成，其中数字采集与存储单元的硬件部分包括电源模块，值班电路模块，数据采集模块，数据存储模块，时钟同步模块。系统采用DSP作为中央处理芯片，利用经过同步后的秒脉冲作为触发信号，实现同步数据采集。以CF卡作为存储介质，实现数据自容式存储。软件部分实现自检、同步、数据采集存储功能。经过测试，系统工作稳定，功能正常，同步精度在100 ns以内。

Abstract

The composition

working mode and function test of the multivariate synchronous data acquisition and storage system based on DSP were introduced from hardware and software aspects. The system was mainly composed of a host computer and a digital acquisition and storage unit. The hardware part of the digital acquisition and storage unit included a power supply module

a duty circuit module

a data acquisition module

a data storage module

and a clock synchronization module. The system used DSP as the central processing chip

and used the synchronized second pulse to trigger the analog-to-digital conversion chip to achieve synchronous data. The CF card was used as a storage medium to realize data self-storage. The software part realized self-checking

synchronization

data acquisition and storage functions. The testing results show that the system functions are stable

and the synchronization precision is within 100 ns.
