Design And Implementation Of Three Dimensional Visualization System For Coverage Analysis Of Power Wireless Private Network

Nowadays,the new generation of mobile network(5G)mobile network has become the focus of the industry.5G mobile network has the characteristics of large broadband,low delay and so on,which has a strong support for the implementation of smart grid.In the construction of electric power private network,network planning is one of the indispensable links.Through network planning,the network performance of the actual network can be evaluated,the balance between demand and cost can be achieved,and the complexity of subsequent network maintenance can be reduced.The traditional overlay simulation results are generally displayed in the way of two-dimensional plane graphics.Compared with two-dimensional display,the three-dimensional visualization of overlay simulation results has more abundant and specific,and the sense of layer and stereo is more prominent.Three-dimensional has the irreplaceable advantages of two-dimensional display.The coverage simulation of power private network is an important part of power private network planning.This paper mainly studies the application of coverage simulation of LTE and NR in power wireless private network and how to display the simulation results in three dimensions.The main work of this paper includes four parts.(1)This paper studies the related contents of power private network and network planning,compares some differences between LTE and NR,and summarizes the key technologies of 5G.(2)The coverage simulation algorithm is designed,and the LTE and NR coverage simulation systems are programmed according to the coverage simulation algorithm.(3)The 230MHz and 1800MHz frequency bands used in LTE and 700MHz frequency band used in NR of power private network are studied.The power distribution and power consumption business of power private network are modeled.The coverage simulation and capacity simulation of these three frequency bands are carried out respectively,and the simulation results are rendered.(4)Using map data and community data to build a three-dimensional model of the building.The rendered coverage simulation data is imported into the three-dimensional building and the three-dimensional visualization of the coverage simulation results is completed.
