多终端配网现场可视化监控系统研究

Research on Multi-Terminal Distribution Network Field Visualization Monitoring System

为实时、同步监控多终端配网现场作业状态,对基于5G通信的多终端配网现场可视化监控系统进行了研究。系统分为采集层、网络层和展示层。采集层在利用监控摄像头采集多终端配网现场作业的视频信号后,以全电视信号的方式,将视频信号通过网络层5G通信模块的5G通信网关传输至展示层。展示层中的可视化监控显示模块先将全电视信号解码变换成RGB888格式并传输至现场可编程门阵列执行增强、帧同步处理,再将监控信息在液晶面板高分辨率展示。系统网关使用基于监控时延优化的5G通信网络切片接入优化算法,获取监控时延最小的切片接入方案,以保证系统多终端监控信息的传输实时性。测试结果表明:该系统的监控时延最大值为38 ms。虽然传输速率会随着距离增大而出现小幅增加,但未超过标准区间。该系统的可视化监控效果显著、监控实时性强。

To real-time and synchronous monitoring of multi-terminal distribution network field operation status,a multi-terminal distribution network field visualization monitoring system based on 5G communication is studied.The system is divided into acquisition layer,network layer and display layer.After collecting the video signals of multi-terminal distribution network field operation by monitoring camera,the acquisition layer transmits the video signals in the form of full TV signals to the display layer through the 5G communication gateway of the 5G communication module in the network layer.The visualization monitoring display module in the display layer firstly decodes and converts the full TV signals into RGB888 format and transmits the signal to the field-programmable gate array to perform enhancement and frame synchronization processing,then displays the monitoring information on the liquid crystal panel in high resdution.The system gateway uses the 5G communication network slice access optimization algorithm based on monitoring delay optimization to obtain the slice access scheme with the smallest monitoring delay to ensure the real-time transmission of multi-terminal monitoring information in the system.The test results show that the maximum monitoring delay of the system is 38 ms.Although the transmission rate increases slightly with the distance increases,it does not exceed the standard interval.The visualization monitoring effect of the system is remarkable,and the real-time monitoring is strong.
