摘　　要： 在长距离需要对多路数据进行采集的情况下,提出了一种基于FPGA的多路级联式采集系统。本系统以FPGA为核心,实现对各路采集单元的命令控制和数据传输控制,并且各采集单元相互独立、所采集的数据单独存储。实验测试结果表明,各路采集数据能够可靠传输到读数单元。各采集单元以级联方式连接,可在采集点自由增减采集单元,实现任意路数据的采集与存储。 In the case of long-range multi-channel data acquisition,a FPGA-based multi-channel cascaded acquisition system was presented.This system used FPGA as the core to control the command and data transmission of every acquisition unit,the collected data were stored separately.Experimental results showed that,all the collected data could be reliably transmitted to the reading unit.The acquisition unit was connected in cascade mode,it could increase or decrease acquisition unit arbitrarily in the patch,and realize arbitrary ways of data collection and storage.
