摘　　要：为实现数据采集的实时传输和远程控制,设计并实现了基于W5300和FPGA的实时数据采集系统。系统选用W5300搭建网络模块,采用TCP协议与远程上位机通信,控制以AD7357为核心的A/D模块进行数据采集。通过对系统稳定性和准确性的反复测试,最终可实现两路A/D以1.5 MS/s采样率对50 Hz^750 kHz信号的准确采样并向远程上位机实时传输数据。In order to achieve real-time transmission of data acquisition and remote control, this paper designed and imple-mented the W5300 and FPGA-based real-time data acquisition system. The system chose W5300 to build a network module and communicated with the remote host computer using TCP protocol to control A/D module which based on AD7357 to acqure data. Both channels of AD？357 can accurately sample signal of 50 Hz-500 kHz at 1.5 MS/s rate and transmit the data to the remote host computer real-timely.
