双通道逻辑控制高速实时数据采集系统的设计

Design of logic-controlled dual-wing data-acquisition structure of high-speed & real-time feature

设计了一种全新构架的高性能数据采集系统。采用平衡式双通道对称结构,可对32路输入信号进行灵活控制。系统中采用了高速A/D转换器、大容量的FIFOSRAM、CPLD技术和PCI数据通信接口,实现了实时、高速的数据采集和处理。

An innovatively high performance data acquisition system is designed in this paper, which has 32-channel dualwing symmetric structure. High-speed A/D conversion and a large capacity FIFO RAM are used in the system. CPLD is use for mastering its logic flow, and PCI interface for data transition.
