摘要
介绍了一种双通道并行运行的高速数据采集卡,它采用两片高速A/D转换芯片AD1674,一方面可与传感器通信来获取数据,另一方面可以与计算机进行实时的通信,从而实现对数据的采集、存储等功能的操作。设计中运用了多通道和CPLD技术,简化了系统的硬件设计,可采集16种不同的信号,提高了数据采集的速度和可靠性。
this paper introduces a high-speed double-channel parallel data acqui which oonta,ins two pieces of A/D cenverter chips adt674. It can get data by communicating with sensors and also can communicate with computer which completes the data acquisition, data storage and other Operations. This design applies multi-channel and CPLD technology. It makes system＇s structure mere simple and could acquire 16 different kinds of signals, which improves the speed of data acquisition and system＇s stability.
