Multi-Channel High-Speed and High-Precision Signal Acquisition,Storage and Playback System

Youbin Zhuang, Zhongming Jin, Xing Xiao, Bin Wang, Chi Cao

Abstract


A multi-channel signal acquisition,storage and playback system with high speed and high accuracy is proposed by reprocessing the signals that can’t be processed in real time and reproducing the collected signals in other places.Through FPGA control acquisition system,linear optocoupler is used to fi lter out high-frequency signal interference,ADS1258 realizes the conver-sion of 16 channels of analog data,asynchronous buff ering technology buff ers high-speed data,and sampling voting and delay fi l- tering are combined to improve the stability of switch control instructions,and fi nally 16 channels of data are collected and stored.

Keywords
