Embodiment Construction

[0015] In order to make the technical problems, solutions and beneficial effects to be solved by the present disclosure clearer and clearer, the following in conjunction with the appended Figures 1 to 4 The present invention will be described in detail with reference to specific embodiments. The specific embodiments described here are only used to explain the present invention, and are not limited thereto.

[0016] In one embodiment, the present disclosure discloses a roaming method of a LoRa-based wireless Internet of Things device, the method comprising the following steps:

[0017] S1. Gateway startup initialization: if the gateway does not have registration information, then request registration to the cloud server; if the gateway has registration information, then enter step S2;

[0018] S2. The gateway requests the node device list from the cloud server;

[0019] S3, node device initialization, if the node device has a device identifier, the node device sends a networ...

Abstract

The present invention discloses a roaming method of wireless internet-of-things device based on LoRa. The method comprises the following steps that: a node device sends a network access request to gateways: the node device sends a broadcast message to require communication with all the gateways in a communication range of the node device, the node device obtains an MAC address returned by the gateways, and the node device sends a network access request to the gateways; S2, the node device dynamically obtains the signal intensity indication received by all the gateways in the communication range of the node device: the node device sends the broadcast message in the heartbeat to obtain the signal intensity indication received by all the gateways in the communication range of the node device;and S3, the node device selects connection with a certain gateway according to the signal intensity indication of the gateways. The node device can freely move between the gateways to automatically and seamlessly achieve switching between the gateways so as to greatly improve the motion range of the node device.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a roaming method of a LoRa-based wireless Internet of Things device. Background technique [0002] Roaming is a term commonly used by mobile phone users to refer to the ability to continue using their mobile phone in some other region or country when the mobile phone leaves the region or country. In the field of the Internet of Things, there are basically few devices that can realize the roaming networking function. The main reason is that the terminal equipment scene is generally fixed, there is no need for roaming, and LoRa technology cannot roam. In recent years, with the development of Internet of Things technology, more and more LoRa-based Internet of Things devices have mobile requirements and need to achieve seamless communication with gateways in other regions. These LoRa-based wireless IoT devices, because they have no roaming function, lose ...
