Gateway of Internet of things and automatic adaptation method of communication protocol

Abstract

The invention relates to a gateway of the Internet of things, which comprises a standard interface connector for inserting wireless sensing units, an information receiving module for receiving information of the wireless sensing units through the standard interface connector, a protocol query model for querying applicable protocol stacks from a management platform of the Internet of things at the network side according to the received information of the wireless sensing units, a protocol deployment module for downloading the queried protocol stacks applicable to the wireless sensing units into the gateway of the Internet of things for deployment, and a protocol conversion and adaptation module for carrying out protocol conversion and adaptation between nodes in a wireless sensor network and the management platform of the Internet of things according to the deployed protocol stacks and a message protocol format defined by the management platform of the Internet of things. In the invention, the gateway of the Internet of things can insert different wireless sensing units according to the specific need of the wireless sensor network and queries and downloads the protocol stacks corresponding to the wireless sensing units from the management platform of the Internet of things so as to adapt to various wireless networks rapidly.

Description

technical field [0001] The invention relates to the application technology of the Internet of Things, in particular to an Internet of Things gateway and a method for automatically adapting communication protocols to sensor nodes using different technologies. Background technique [0002] The concept of the Internet of Things (The Internet of Things) was first proposed by the Massachusetts Institute of Technology (MIT) in 1999. The original concept refers to connecting all items to the Internet through radio frequency identification (RFID) and other information sensing devices. A network that realizes intelligent identification and management. The International Telecommunication Union (ITU) expanded the meaning of the concept of the Internet of Things in 2005. The report pointed out that the goal of information and communication technology has developed from connecting anyone at any time and anywhere to the stage of connecting any object, and The connection of all things for...

Problems solved by technology

However, the current Internet of Things gateway devices have the following shortcomings: First, because there are many short-distance wireless transmission technologies and lack of unified standards, RFID, ZigBee, Bluetooth, Z-Wave, etc. are widely used at present.

However, the technical solution proposed in this patent is only limited to solving how the gateway device adapts to different telecommunication networks so as to realize the convenient transmission of wireless sensor network information in various application scenarios, and does not involve how to adapt to wireless sensor networks with different technical specifications at the front end. Sense network to form a unified interface standard

[0010] Chinese patent CN200610169744.1 proposes a wireless sensor network gateway device, which uses a GPRS wireless unit to realize the communication connection between a remote server and a wireless sensor network, and its technical solution does not involve how to adapt to various wireless sensor networks
