摘　　要：针对变电站监控体系中传输大数据信息有可能出现时间延迟或者不通畅等问题,设计了以OneNet为基础的云平台监控体系以解决上述问题,系统对于视频数据的收集利用高清CCD摄像头实现,将获取到的信息传送给工控板,工控板核心处理器为DSP+ARM双核架构芯片TMS320DM6467T,压缩视频信号是利用以H.264视频数据压缩协议算法来完成的,然后开启WIFI模块将上面获取到的压缩信息然后借助OneNet云平台向后端监控器传输,对于后端监控器来说,需要对视频数据解码后储存,解码是利用PC服务器提供的解码算法实现,解码完成后的视频通过手机端进行浏览。经过实践证实,系统在视频传输时效和播放质量等方面都符合预定标准,发展前景良好。Aiming at the problems of time delay or unobstructed transmission of big data information in substation monitoring system,a cloud platform monitoring system based on onenet is designed to solve the above problems.The system uses high-definition CCD camera to collect video data,and transmits the obtained information to the industrial control board.The core processor of industrial control board is DSP+ARM dual core architecture chip TMS320DM6467T.The compressed video signal is completed by using H.264 video data compression protocol algorithm,and then the WiFi module is opened to transmit the compressed information obtained above to the back-end monitor with the help of onenet cloud platform.For the back-end monitor,the video data needs to be decoded and stored.Decoding is realized by using the decoding algorithm provided by PC server,and the video after decoding is browsed through the mobile terminal.It has been proved by practice that the system meets the predetermined standards in terms of video transmission timeliness and playback quality,and has a good development prospect.
