中文摘要:电力通信网现场运维对于电力通信网以及智能电网的稳定和有效运营至关重要,为了保证电力通信网现场运维作业质量和提高运维作业效率,提出了一种多点远程协同视频通信架构,基于Openfire和WebRTC搭建了即时通信系统,促进运维作业消息的流通,提高运维作业效率。针对目前WebRTC的拥塞控制算法不能根据网络情况实时、准确自适应视频流数据发送速率,在基于时延的拥塞控制算法和基于丢包的拥塞控制算法的基础上,提出了一种基于网络质量感知的视频速率优化方法,该算法能够有效感知网络质量并优化视频发送速率。提供了对提出算法的实验评估,并通过模拟结果提供了与WebRTC适配的拥塞控制算法的对比分析。

Video Rate Optimization Method for Wearable Multi-point Remote Cooperative Operation and Maintenance of Power Communication
Abstract:The field operation and maintenance of power communication network is very important for the stable and effective operation of power communication network and smart grid. In order to ensure the quality of operation and maintenance of power communication network and improve the operation and maintenance operation efficiency,this paper proposes a multi-point remote coordination. The video communication architecture,based on Openfire and WebRTC,has established an instant messaging system to facilitate the circulation of operation and maintenance operations and improve the operation and maintenance efficiency. The current WebRTC congestion control algorithm can not accurately and accurately adapt the video streaming data transmission rate according to the network conditions. This paper proposes a network quality based on delay-based congestion control algorithm and packet loss-based congestion control algorithm. A perceptual video rate optimization method that can effectively perceive network quality and optimize video transmission rate. This paper provides an experimental evaluation of the proposed algorithm,and provides a comparative analysis of the WebRTC-adapted congestion control algorithm through simulation results.
