Problems solved by technology

[0002] In the traditional single-frequency power line carrier communication network, the expansion of the network scale requires multi-level proxy relay nodes, because multi-level relays introduce higher delays and occupy more TDMA (Time Division Multiple Access, Time Division Multiple Access) Access) time slots, and more network sites compete to send on CSMA (Carrier Sense Multiple Access) time slots, which will lead to more conflicts, congestion and decreased channel utilization, which in turn will affect the group Network size is very limited
In addition, the noise distribution and channel attenuation on single-frequency power line carrier communication are frequency-selective, and normal communication may not be possible in certain geographic locations

Abstract

The invention discloses a dual-mode multi-frequency networking method and system based on power lines and wireless, relates to the technical field of communication engineering, and solves the problem that network communication is restricted by single-frequency time slot resources due to the lack of combination of multi-frequency and dual-mode networking Technical problem, the main point of the technical solution is to enhance the network coverage without increasing the load of the upper-level network through the flexible deployment of the secondary master station, combined with the advantages of dual-mode communication; according to the actual communication effect, it can be configured or automatically Switching Conveniently switch to the appropriate frequency band, avoiding the influence of frequency selection by noise.
