基于FPGA和LabVIEW的多通道数据采集系统设计

Design of Multi-Channel Data Acquisition System Based on LabVIEW and FPGA

设计了一套基于FPGA和LabVIEW 2014八通道数据采集系统。该系统具有用户登录、多通道数据同时采集、实时显示、报警记录等各项功能。经验证,整套系统运行简单方便,可以满足工业现场使用,各通道数据采集吞吐速率可达200 k SPS(×103次/S),在-5～+5 V电压输入范围间测量精度高达0.5 m V以内,而且功能便于扩展。该系统可以应用于近代物理研究所加速器运行的温、湿度采集现场。

An 8-channel data acquisition system based on FPGA and LabVIEW 2014 was designed.The system has user login,multi-channel data acquisition,real-time display,alarm records and other functions.It is proved that the whole system is simple and convenient to operate,which can meet the practical application.The throughput of each channel is up to 200 kSPS,and the measurement accuracy is 0.5 mV of less than within the range of -5^+5V voltage input,and the function is easy to expand.This system can be applied to the temperature and humidity acquisition site of Accelerator in the Institute of Modem Physics.
