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

Abstract

The invention provides a networking scheme of a dual-mode hybrid network based on a broadband carrier and narrowband wireless. Intelligent electric meter nodes access the network by adopting a white list system; a broadband carrier single-mode sensor node and a dual-mode sensor node apply for network access in a mode of sending an associated message to a network main node; when a narrowband wireless single-mode sensor node accesses the network, a wireless beacon signal sent by a dual-mode communication node in the network is monitored; after the wireless beacon signal is correctly received , competing is carried out to send a network access application signal; a relay node forwards the network access application signal to the network main node; after receiving the network access application signal, the network main node sends a network access agreement signal to the relay node; after receiving the network access agreement signal, the relay node forwards a network access agreement signal to the narrowband wireless single-mode sensor node applying for network access; and the narrowband wireless single-mode sensor node applying for network access completes network access after receiving the network access agreement signal. According to the invention, hybrid networking and efficient communication requirements of devices with different forms and communication capabilities can be met.

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
