A method for automatic intercommunication of different protocols of the Internet of Things and an Internet of Things terminal

Abstract

The invention relates to a method for automatically interconnecting different protocols of an Internet of things and an Internet of things terminal. The method is applied to an Internet of things communication system which comprises the Internet of things terminal needing service, the Internet of things terminal providing the service and a server side. The method comprises the steps that the Internet of things terminal providing the service sends broadcasts of providing service types and providing service protocol types to the server side; the server side forwards the broadcasts of the providing service types and the providing service protocol types to the Internet of things terminal needing the service; the Internet of things terminal needing the service sends a service request message to the Internet of things terminal providing the service; and the Internet of things terminal providing the service provides the service. According to the method and the Internet of things terminal, through adoption of an MQTT server based on the Internet of things protocol conversion, the Internet of things protocols of different manufacturers can be mutually converted in real time. The Internet of things terminals in the Internet of things can sense mutual service and protocol types. Different Internet of things terminals can trigger real-time bidirectional protocol conversion.

Description

technical field [0001] The invention relates to the technical field of Internet of Things communication, in particular to a method for automatic intercommunication of different protocols of the Internet of Things and an Internet of Things terminal. Background technique [0002] The current status of the IoT Internet of Things is that standard certification lags behind technological development, just like the development history of communication technology, it has become another sample of formal standard setting lagging behind. Usually, formal standards should help shape the technology. Official certification bodies that can formulate standards are far from catching up with the pace of technological development. Since formal standards have not appeared in time, de facto standards have become the norm. Various manufacturers and protocol alliances have developed their own unique IoT communication protocols for their own development and mutual competition needs. For example, th...

Problems solved by technology

[0004] Since there is no unified standard for the Internet of Things, the current Internet of Things protocols are relatively scattered, independent and incompatible protocols, and the protocols cannot directly communicate with each other (for example, the AllJoyn protocol and Apple's HomeKit protocol cannot directly communicate with each other)

Most of the current Internet of Things protocols are based on the Wi-Fi TCP / IP protocol to achieve different applications, and the application layer implementations of different manufacturers are not very different, and they cannot directly communicate with each other.

There are many IoT protocols, and each protocol cannot automatically identify each other

After the Internet of Things protocol recognizes the protocol type of the other party, it cannot automatically perform two-way protocol intercommunication in real time
