摘要

设计了一种以现场可编程门阵列（FPGA）为核心的数据采集系统。系统具有4个采集通道

直接通过上位机的指令配置

可根据实际需求选择实时采样或高速采样。设计了采集系统的硬件电路

开发了FPGA程序

以实现数据采集、存储、自动电桥平衡、状态反馈等功能

采用RS-232串口方式与上位机通信。实验证明:系统实现了预期功能

可达到实时采样频率为2.88 kHz和高速采样频率为91.5 kHz的数据采集。

Abstract

A data acquisition system based on field programmable gate array（ FPGA） is designed. The system has four acquisition channels. It is configured by commands of host computer

and can choose real-time sampling or high-speed sampling according to actual needs. Hardware circuit of the acquisition system is designed. FPGA program is developed to implement functions such as data acquisition

data storage

automatic electric bridge balance

and status feedback. FPGA communicates with the host computer via RS-232 serial port. The test shows that the expected functions are implemented

and the system can achieve 2. 88 kHz in real-time sampling and91. 5 kHz in high-speed sampling.
