为了实现变电站自主巡视机器人稳定可靠的传输高清图像，采取了WLAN与3G/GPRS 相结合的方式，采用稳定可靠的3G/GPRS 网络传输必须的图像数据，而采用 WLAN 网络传输非必须的高清实时视频信息。设计了图像服务器与控制客户端，针对不同的摄像机分别采用专用SDK与开源Live555+FFmpeg项目实现各个子函数。图像服务器能正确地传输图像数据和转发实时视频流。控制客户端可以接收保存图像数据和播放实时视频，图像清晰且传输时延较小。

In order to achieve reliable and steady transmission of HD images, substation autonomous patrol robot uses a combination of WLAN and 3G/GPRS. The robot uses reliable and steady 3G/GPRS network to transmit necessary image data, and uses WLAN network to transmit unnecessary real-time HD videos. This paper designs an image server and a control client, implements each subroutine for different cameras by using a dedicated SDK and the open source project Live555+FFmpeg. The image server can transmit image data and forward real-time video stream correctly. The control client can receive and save image data and play real-time video, the images is clear and the transmission delay is small.
