Internet of things gateway

Abstract

The invention provides an Internet of things gateway, which comprises an interface connection module, an information receiving module, and a protocol conversion module, wherein the interface connection module is used for being connected with a wireless sensing terminal for data interaction; the information receiving module is used for receiving sensing data via the interface connection module from the wireless sensing terminal and sending control information to the wireless sensing terminal; and the protocol conversion module is used for converting a message protocol in a JSON type defined by an Internet of things management platform into an actual control protocol corresponding to the wireless sensing terminal according to the type of the wireless sensing terminal or converting the sensing data to a JSON type format in a unified mode and sending the format to the Internet of things management platform, thereby realizing protocol conversion and matching between each node and the Internet of things management platform in a wireless sensing network.

Description

technical field [0001] The present invention relates to the application technology of the Internet of Things, and in particular, relates to a gateway of the Internet of Things. 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 with the Internet through radio frequency identification (RFID) and other information sensing devices to achieve intelligence. Identify and manage networks. 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 forms the Internet of Things. [0003] In the Internet of Things mentioned in this report, in a...

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.

Even for the same transmission technology, such as ZigBee, the actual application standardization is not high. Many manufacturers develop transmission modules or transmission chips based on private protocols, so ZigBee chips from different manufacturers cannot communicate with each other.

Therefore, wireless sensor networks are often heterogeneous. Currently, IoT gateway devices on the market are often customized only for specific cases, which is not conducive to the large-scale development of the IoT industry. How can gateway devices adapt to these heterogeneous wireless sensor networks? The difference of wireless sensor networks enables collaborative work between heterogeneous wireless sensor networks and between wireless sensor networks and communication networks, which is an urgent problem to be solved

[0008] In addition, the current gateway device only transparently forwards the sensor network information, which makes many industry IoT application systems in a localized and separated state. Various front-end information sensing devices adopt various standards, and many of them use enterprise private The collected information is also limited to dissemination, analysis and processing in a small range of industry-specific application scenarios, without truly realizing the construction goals of the Internet of Things being operable, manageable, controllable, trustworthy and information sharing
