An Internet of Things virtual gateway and node access authentication method compatible with multiple protocols

Abstract

The invention belongs to the field of Internet of things technology, and discloses an Internet of things virtual gateway and node access authentication method compatible with multiple protocols. The specification defined by an Internet of things data support platform only requires a virtual gateway to follow the adaptation, the process that the virtual gateway uploads data or receives commands follows the specification defined by the Internet of things data support platform, the virtual gateway is adapted to different Internet of things sensing equipment downwards and is developed according to the protocols and data formats of the Internet of things sensing equipment, and when a new type of Internet of things sensing equipment is accessed, only one virtual gateway needs to be developed and adapted to the new Internet of things sensing equipment downwards, the existing code of the Internet of things data support platform does not need any change, and thus a new type of Internet of things sensing equipment can be accessed with minimum cost; and meanwhile, the virtual gateway authenticates the Internet of things sensing equipment, a cloud platform authenticates the virtual gateway, and thus the security and legality of the data can be guaranteed through layer-by-layer authentication.

Description

Technical field [0001] The invention belongs to the technical field of the Internet of Things, and particularly relates to an Internet of Things virtual gateway compatible with multiple protocols and a node access authentication method. Background technique [0002] At present, with the widespread application of Internet of Things technology, the types and numbers of connected Internet of Things sensing devices are increasing, and the transmission protocols, communication protocols, and data transmission formats used by sensing devices in different regions or even in the same region are also different. The same, but the current Internet of Things access technology still has insufficient compatibility with all kinds of sensing devices. It can only access specific types of Internet of Things sensing devices, supports several mainstream data transmission protocols, and analyzes specific The data format is difficult to integrate various IoT sensing devices, making the IoT data suppor...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: due to the different data transmission protocols and data formats used by the Internet of Things sensing devices produced by various manufacturers, it is difficult for the current Internet of Things access technology to be compatible with a large number of types of sensing devices. The data support platform can only access the sensing devices produced by specific manufacturers, so that ordinary users of a certain platform cannot realize plug-and-play after purchasing devices from any manufacturer, which seriously affects the user experience
