Spatial Positioning and Regional Intrusion Monitoring Method Based on 3D Real Scene Model of Converter Station

At present, the converter station mainly monitors regional intrusion through manual inspection, which has low monitoring efficiency and is prone to mistakes, which can not ensure the security of key areas of the converter station. In view of the above problems, a spatial positioning and regional intrusion monitoring method based on the three-dimensional real scene model of the converter station is proposed. The three-dimensional real scene model of converter station is constructed by ANSYS modeling method; Based on the three-dimensional real scene model, locate the three-dimensional warning space; Target tracking algorithm is used to monitor intrusion characters. The experimental results show that for five intrusion events, the average deviation of monitoring is always less than 1.675m, the deviation of positioning warning space is small, and has better spatial positioning effect; The highest missed detection rate and the highest false detection rate are not more than 1%, and the monitoring accuracy is high; The overall average monitoring time is 0.53s, which improves the monitoring efficiency and ensures the safety of key areas of the converter station.
