| 摘 要： | 针对变电站实时监控系统需要传输的数据量大和传统的百兆网络已无法满足传输总带宽需求的问题，文中设计了嵌入式千兆以太网视频传输系统。该系统选用Xilinx公司Artix-7系列的FPGA芯片为主控制器，完成数据的采集、处理和传输控制。使用UDP/IP协议帧通过千兆以太网向远程监控系统传输图像数据时，丢包率仅为0.001 25%。在对变电站高压设备进行监控传输测试时，稳定传输视频图像的最高帧频可达150 frame·s-1。

| Abstract: | For the problem of large amount of transmitting data in substation real-time monitoring system and the traditional transmission network has been unable to meet the demand of the total transmission bandwidth, the embedded Gigabit Ethernet video transmission system has been designed. The system uses the Artix-7 series FPGA chip of Xilinx company as the main controller to complete the data acquisition, processing and transmission control. When using the UDP/IP protocol frame to transmit the image data to remote monitoring system through the gigabit Ethernet, the packet loss rate is only 0.00125%. In the monitoring transmission test on high voltage equipment in substation, the maximum frame rate of stable video image transmission is up to 150 frames per second. |
