Design And Realization Of An Ultra-high Speed Portable Data Acquisition & Storage System

A kind of Ultra-high Speed Portable Data Acquisition and Storage System isdesigned in this thesis, which is based on Universal Serial Bus (USB) technology withadvantage of high speed, HotPlugIn, Plug and Play, easily to interconnect and takingless system resource. Combined with today's high-performance FPGA, ultra-high speedA/D conversion device and solid-state memory FLASH (Flash), the system can storeacquisition data and replay it in the computer.In view of the defects of the existing Data Acquisition System in fields of military,industrial measurement and control, this paper presents a low-cost, high-performancemass data acquisition and storage solutions. After analyzing the system requirements,the system's overall scheme deign is given firstly in accordance with the differencebetween software and hardware. Based on those introductions, the paper emphaticallydiscusses the design and implement of data acquisition subsystem, data storagesubsystem and shows the results of timing simulation. Finally, the paper introduces thefirmware, driver and client software development, and then gives the functionalverification of the whole Ultra-high Speed Portable Data Acquisition and StorageSystem. The key tecnologies in this system are methodology of ultra-high speed signalconditioning, ultra-high speed A/D conversion, transmission and anti-interferencetechnology for ultra-high speed signal.The functional verification shows that the Ultra-high Speed Portable DataAcquisition and Storage System with advanced technology provides a more effective,economical and portable way for ultra-high speed data acquisition, storage and transfer.
