Virtual Internet-of-things gateway system capable of realizing multiprotocol and network self-adapting

Abstract

The invention discloses a virtual Internet-of-things gateway system capable of realizing multiprotocol and network self-adapting; and the gateway system uses a virtual Internet-of-things gateway to connect a sensor network with a traditional communication network and realize the protocol conversions of different types of sensor networks, equipment local interconnect and remote control. The invention is characterized in that the virtual Internet-of-things gateway contains a sensing access module in a sensing access layer, a protocol adaptation module and a network element service module which are in a protocol adaptation layer, a thing-connecting service control module in a control layer, and a heterogeneous network access module in a wide area access layer; the entire system adopts the virtual gateway method; the gateway equipment of the virtual Internet-of-things gateway system are arranged and only a plurality of physical interfaces are required to be added without greatly changing the internal circuit structure, thus the various demands of the future network can be satisfied and the development demand of the future Internet of things can be satisfied; and the incompatibility problem of the existing common gateway to the future Internet of things is effective solved, thus the gateway in the virtual gateway system has wide network applicability.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a virtual Internet of Things gateway and technology for realizing interconnection between an Internet of Things perception network and an existing basic network by using a virtual machine principle. Background technique [0002] With the continuous advancement of information and communication technology, the communication network, as an important foundation of information and communication technology, has developed from people-to-people communication to people-to-things and things-to-things, and gradually tends to transition from vertical local things to horizontal cross-application and cross-region IoT. The concept of the Internet of Things was proposed in 1999. Its definition is very simple, that is, to connect all items to the Internet through radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners and other information ...

AI Technical Summary

Problems solved by technology

For example, the existing sensor network technology. Because the nodes are generally powered by batteries, the power consumption must be very low. Computing and storage resources must be limited, and a series of characteristics such as communication bandwidth, transmission distance, and coverage must be reduced.

In addition, there are many types of sensing technologies, and different communication protocols are used. Interconnection cannot be realized at all.
