摘　　要：论文介绍了一种在FPGA下,基于NiosⅡ的以太网数据采集平台设计方案。采用TI公司的ADS1278芯片进行8路信号的同步采集,由集成有TCP/IP硬件协议栈的以太网芯片W5300实现以太网通讯。该系统可裁剪并可以方便地添加算法单元,同时可扩展性好,易于进行数据的分布式处理。具有传统的集成电路无法比拟的优势。A design scheme about Ethernet data collection based on FPGA is introduced. The system uses TI Corporation＇s ADS1278 to complete the synchronous sampling of 8-channel signal, and finishes Ethernet communication through W5300 which has the function of TCP/IP. This system can be cut and convenient to add algorithm unit. What is more, the system is extensible, and easy to perform data distributed processing. It has the incomparable advantage over the traditional integrated circuit.
