Embodiment Construction

[0061] Such as Figure 4As shown, the present invention discloses a LoRa-based networking method (a mesh multi-hop networking method based on LoRa communication between a set of gateways), which solves the coverage problem of the LoRa network in an environment without an IP network. This networking method is called LoRa Enhanced Wide Area Network (hereinafter referred to as "LoRaAWAN"). And this networking method takes into account the self-healing of the entire network when the gateway fails, as well as the visual monitoring of LoRa network coverage.

[0062] Such as Figure 4 As shown, the gateway directly connected to the cloud server through the IP network is called the main gateway, and the LoRa communication hop count between the main gateway and the cloud server is 0 (the hop count of the gateway refers to the number of gateways that the gateway needs to pass through to communicate with the cloud server ).

Abstract

The invention provides a networking method and system based on LoRa. The networking method comprises the following steps: a gateway directly connected with a cloud server via an IP network is called as a main gateway, the LoRa communication hop of the main gateway and the cloud server is zero, and the hop of the gateway refers to the number of gateways that need to be passed when the gateway communicates with the cloud server; a gateway that has no the IP network and cannot be directly connected with the cloud server is called as a daughter gateway, and the daughter gateway is connected with the main gateway or other daughter gateways; and a terminal is enabled to be connected with the daughter gateways. The networking method and system provided by the invention have the following beneficial effects: under an environment without the IP network, the LoRa network coverage range is greatly increased; and by virtue of a self-healing network, under a condition that a certain gateway or some gateways have a fault, the communication still can be kept between the terminal and a server; and with a visualized network coverage, the equipment can be conveniently expanded and maintained.

Description

technical field [0001] The present invention relates to the technical field of wireless device networking, in particular to a LoRa-based networking method and system. Background technique [0002] The existing LoRaWAN networking methods are: [0003] 1. The terminal device (hereinafter referred to as "terminal") is connected to the LoRaWAN gateway (hereinafter referred to as "gateway") through LoRa wireless communication (hereinafter referred to as "LoRa communication"). [0004] 2. The gateway is connected to the IoT cloud server (hereinafter referred to as "cloud server") through an IP network (Internet or local area network). [0005] 3. Gateways cannot be connected through LoRa wireless communication. [0006] 4. The cloud server is the center of the entire LoRaWAN, which is responsible for controlling or data collection of each terminal. [0007] The topology of traditional LoRaWAN ( figure 1 ): [0008] 1. From the perspective of terminals and gateways ( figure ...
