基于FPGA实现多路模拟信号自适应采集系统

Multi-channel Analog Signal Self-adaptive Acquisition System Based on FPGA

主要介绍基于FPGA实现多路模拟信号自适应采集系统的设计。该系统主要包括软件和硬件两部分:硬件主要采用FPGA芯片,AD7982-1,ADG406和运放AD824来搭建硬件平台;软件包括FPGA程序和事后数据处理程序。系统采用动态8位量化方式克服了固定8位量化对信号采集精度的影响,目前已成功用于产品中。

Thedesign of the multi-channel analog signal self-adaptive acquisition system based on FPGA is introduced, which is mainly composed of software and hardware. The hardware platform is built with FPGA, AD7892-1, ADG406, AD824 and so on. The software includes FPGA and expost data processing programs. The inflccence of the 8 bit fixed quantification on the signal acquisition accuracy was overcome by the system with 8 bit dynamic quantification. The system has been applied in the relative products successfully.
