Networking method of dual-mode hybrid network based on broadband carrier and narrowband wireless

Abstract

Based on the networking scheme of the dual-mode hybrid network of broadband carrier and narrowband wireless, the smart meter node adopts the white list system to access the network; the broadband carrier single-mode sensor node and dual-mode sensor node apply for network access by sending associated messages to the network master node; When the narrowband wireless single-mode sensor node enters the network, it first monitors the wireless beacon signal sent by the dual-mode communication node in the network; after receiving the wireless beacon signal correctly, it competes to send the network application signal; the relay node forwards the network application signal to the network master node ; After the network master node receives the network access application signal, it sends a network access approval signal to the relay node; after the relay node receives the network access approval signal, it forwards the network access approval signal to the narrowband wireless single-mode sensor node applying for network access; The single-mode sensor node completes the network access after receiving the network access approval signal. The invention can meet the mixed networking and high-efficiency communication requirements of devices with different forms and communication capabilities.

Problems solved by technology

In traditional physical networks, the transmission of sensor data generally uses narrowband wireless communication technologies based on IEEE 802.15.4 standards, such as ZigBee and LPWAN, etc., but when power sensors are deployed indoors, between tall buildings or in shielded places, the transmission distance of wireless signals will be limited Large limitations, prone to communication isolated points or islands, make the traditional single-mode communication network scheme based on narrowband wireless unable to fully realize the effective communication of power sensor equipment in some complex deployment environments
