Abstract

The invention discloses a high-reliability Zigbee ad hoc network system adopting multiple NB-IoT (Narrow Band Internet of Things) node gateways in the technical field of wireless communication and Internet of Things. The system comprises a plurality of NB-IoT base stations, a plurality of Zigbee node modules, a plurality of NB-IoT node gateways, the Internet and a monitoring cloud server, any oneNB-IoT base station is in signal connection with the Internet; the Internet is in signal connection with a monitoring cloud server; any NB-IoT base station is in signal connection with the adjacent NB-IoT node gateway; the plurality of Zigbee node modules and the plurality of NB-IoT node gateways form a signal path. By adopting multiple NB-IoT node gateways, mutual backup of connection between theInternet and the monitoring cloud server is provided, the reliability of remote monitoring of the Zigbee ad hoc network system is greatly improved, and the application scene and the application rangeof Zigbee networking are expanded.

Description

technical field [0001] The invention relates to the technical fields of wireless communication and the Internet of Things, in particular to a high-reliability Zigbee ad hoc network system using multiple NB-IoT node gateways. Background technique [0002] Because Zigbee communication adopts the proxy / forwarding mechanism, it supports a large number of networking nodes and has extremely low power consumption, so it has been widely used in the field of Internet of Things. However, as a wireless communication method, Zigbee is not sensitive enough and is greatly affected by wall signal attenuation. So Zigbee can only be used for short-distance or home / community communication. How to improve the sensitivity of Zigbee to achieve better wall-penetrating ability is a problem that has been faced. In addition, because Zigbee has no direct interface with common routers and mobile phones, communication protocol conversion must be performed before reaching the Internet, which also limi...
