基于 Zynq 的 16 通道高精度数据采集系统

为了提高数据采集的精度和速率,设计了高精度、多通道的数据采集与显示系统。为了精准实现多通道数据采集与显示功能,使用赛灵思公司的 Zynq-7000 系列芯片以及 AD7606 完成多通道数据采集与显示。在设备软件设计方面, A / D 转换完成后存入 DDR3 存储器,然后采用 AXI4 总线与可编程逻辑( PL )部分通信,最后通过 ARM 驱动完成数据的实时显示。经实验证明,该系统可以良好地实现 16 通道的数据采集功能。

Sixteen-channel High-precision Data Acquisition System Based on Zynq

In order to improve the accuracy and speed of data acquisition , a high-precision , multi-channel data acquisition and display system is designed.In order to accurately realize the multi-channel data acquisition and display function , the Zynq-7000 series chip of Xilinx company and AD7606 are used to complete the multi-channel data acquisition and display.In terms of equipment software design , after A / D conversion is completed , it is stored in DDR3 memory , then AXI 4 bus is used to communicate with programmable logic ( PL ), and finally the real-time display of data is completed through ARM drive.The experiment shows that the system can well realize the 16 channel data acquisition function.
