Research on Multi-Terminal Distribution Network Field Visualization Monitoring System
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.
