Design of High-speed Data Acquisition System Based on FPGA and ARM

数据采集是完成信号分析、信息处理的必要前提。能够对高速数据精确采集、信号实时处理,在现场测控系统中起到至关重要的作用。文章介绍了采用FPGA控制高精度高采样率的A/D电路对高频信号实时采集,以ARM处理器做为数据远程传输的控制器,通过DM9000实现高速数据网络传输,将数据存储在远程PC端。通过实验测试表明,该高速数据采集远程实时存储系统可以稳定的采集各类高频信号,能够广泛应用于多种现场测控系统,具有极大的应用价值。

Data acquisition is the necessary premise to complete signal analysis and information processing.It can be used for accurate data collection and signal processing of high-speed data,which plays a crucial role in the field measurement and control system. A/D circuit controlled by FPGA with high precision and sampling rate is used to perform real-time acquisition of high freduency signal,ARM processor as the controller of data remote transmission,high-speed data network transmission are realized by DM9000,store the data in the remote PC.The experimental tests show that the high-speed data acquisition remote real-time storage system can gather all kinds of high frequency signal steadily,can be widely used in a variety of field measurement and control system,has a great application value.
