WLAN anti-interference for high-voltage overhead transmission lines based on comprehensive sensing of spectral posture

With the development of wireless communication technology, wireless communication is gradually used in monitoring data transmission of HV transmission lines, but there are some problems such as strong electromagnetic interference in data transmission and throughput decline of users at the edge of the interval. To solve this problem, an anti-interference technology based on spectrum situation comprehensive perception is proposed, the spectrum detection results of all nodes are equally analyzed and decided, the advanced interval interference coordination technology is used to allocate network resources, the interference is divided into static and dynamic types, and the edge band occupancy rate is used to coordinate interference. The experimental results show that the average user throughput of the advanced interval interference coordination technology is 0.71Mbps and 0.21Mbps higher than that of other algorithms in the solid state scene, and the maximum convergence value of the advanced interval interference coordination technology is 13 and 5 higher than that of other algorithms, respectively. The average user throughput of the advanced interval interference coordination technique is 0.19Mbps and 0.13Mbps higher than other algorithms, respectively. Thus, interference coordination can effectively improve the performance of edge users, accurately predict the user's access base station, and reduce the impact of electromagnetic interference. This study provides a reference for the interference coordination of the cell in the future wireless LAN anti-jamming technology.
