Lora gateway with adaptive channel function and network system based on lora gateway

Abstract

The invention discloses a LoRa gateway with a channel self-adaption function and a network system based on the LoRa gateway. The LoRa gateway is additionally provided with a LoRa broadcast radio frequency module, the LoRa broadcast radio frequency module works in a broadcast channel, and under control of a processor, the LoRa broadcast radio frequency module intermittently sends out LoRa broadcastfor the LoRa gateway and intermittently receives external LoRa broadcast, wherein the external LoRa broadcast is LoRa broadcast sent out by other LoRa gateways, and the LoRa broadcast contains information of a wireless channel which is occupied by a LoRa interaction radio frequency module of the LoRa gateway at present to serve as a working channel; and the processor selects a wireless channel which is not occupied by the LoRa gateways sending out the external LoRa broadcast at present to serve as the working channel of the LoRa interaction radio frequency module. The LoRa gateway has a channel self-adaption function and can avoid the problem that due to the fact that the adjacent LoRa gateways use the same wireless channel competitively, communication of both of the two LoRa gateways fails, so that the communication efficiency of a network formed by the LoRa gateways is greatly reduced.

Description

technical field [0001] The invention relates to a LoRa gateway with an adaptive channel function and a network system based on the LoRa gateway, belonging to an Internet of Things gateway, that is, a networked network system. Background technique [0002] LoRa communication technology is a wireless communication technology applied to low-power wide-area networks. LoRa communication technology has been widely used due to its excellent characteristics of long communication distance and low energy consumption. [0003] A gateway is a network-to-network connector, which plays a key role in various applications as a bridge connecting the Internet, the perception network, and specific device terminals. When deploying a LoRa network in a community, a single traditional LoRa gateway cannot cover the entire community. If multiple traditional LoRa gateways are used to cover the entire community, the adjacent LoRa gateways will compete to use the same channel, causing both parties to f...
