Universal network communication system based on MQTT protocol

Abstract

The invention discloses a universal network communication system based on an MQTT protocol. The system comprises a mobile application side, a home intelligent terminal side and an internet side. The mobile application side comprises an information sending strategy module and an MQTT client side. The home intelligent terminal side comprises a first MQTT Broker message server, an MQTT server side, areceived information filtering module and a service processing module, and a second MQTT Broker message server is deployed on the Internet side. According to the invention, rapid selection of communication lines in different network environments is realized based on the MQTT protocol, so that a mobile application can keep efficient and smooth communication with a home intelligent terminal in a complex and changeable network environment to meet the requirements of service functions of the mobile application.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a general network communication system based on the MQTT protocol. Background technique [0002] Home smart terminals, such as smart speakers, routers, set-top boxes, smart home gateways and other smart terminal devices used in fixed home scenarios, such devices usually use an embedded Linux operating system, can connect to the Internet, and have corresponding mobile terminal supporting applications to cooperate Realize specific business. [0003] Mobile applications, applications running on mobile terminals such as mobile phones, can remotely or locally control home smart terminal devices to achieve their specific services, such as controlling smart speakers to play audio resources, controlling routers to configure networks, and controlling set-top boxes for virtual remote operations. Smart home sub-devices, etc. [0004] MQTT (Message Queuing Telemetry Transport, Messag...

Problems solved by technology

[0006] At present, the common practice is to use MQTT, WebSocket and other protocols on the Internet side to communicate between mobile applications and home smart terminals. Since there is no NAT traversal problem on the LAN side, TCP / UDP is used directly for Socket programming communication. Different, resulting in the need to use different implementation methods for communication on the Internet and LAN sides, which greatly increases the complexity of the program and reduces the maintainability of the software system. At the same time, because this method needs to make communication route decisions based on its own network status, Therefore, it is often impossible to dynamically select the optimal communication route for each piece of information
