Problems solved by technology

This kind of burning and registration method is cumbersome, and it needs to be burned again after the device information is leaked
After the sub-device is registered, it needs to be bound to a gateway before it can be counted. For the movable sub-device, the gateway binding may need to be replaced frequently. The manual networking method of binding the gateway cannot adapt to the scenario of frequent gateway replacement.
Manual registration and manual networking have great limitations
(2) Provide dynamic registration of directly connected devices through the HTTP interface or MQTT channel. The existing dynamic registration method cannot realize automatic networking for non-directly connected devices

Abstract

The embodiment of the invention provides a sub-device registration method in the Internet of Things, a cloud server and a gateway device. The method comprises the following steps: receiving a sub-device self-registration request from the gateway device; generating second signature information according to the gateway information, the sub-device information, the random number and a pre-acquired second sub-device model password; judging whether the first signature information is matched with the second signature information; and if the first signature information is matched with the second signature information, creating a topological relation between the sub-device and the gateway device according to the sub-device information and the gateway information, and generating sub-device registration information. Thus, dynamic registration and dynamic networking of the sub-devices are automatically completed through communication between the gateway device and the cloud server, and automatic networking of the sub-devices in the Internet of Things can be achieved more safely and effectively.

Description

technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular, to a sub-device registration method, a cloud server and a gateway device in the Internet of Things. Background technique [0002] In the existing Internet of Things, there are generally direct-connected devices and indirect-connected devices. Direct-connected devices refer to gateway devices directly connected to the IoT platform. Gateway devices have device management capabilities and can manage multiple indirect-connected devices. Indirect devices are sub-devices that need to be connected to the IoT platform through a gateway device. In the prior art, the following solutions are generally used for the device registration process: (1) Device connection information is generated in batches, and pre-burned device firmware is provided offline for sub-devices. This kind of burning and registration method is cumbersome, and after the device information is l...
