Design And Implementation Of Internet Of Things Cloud Platform Based On MQTT

At present,the Internet of Things has been integrated into all aspects of our lives.However,due to the inconsistency of platform communication protocols and the poor reliability of mobile network communication,there is still a lack of high-performance intelligent Internet of Things cloud service platform which can meet the needs of the vast industry.This study chooses the lightweight and highly reliable MQTT communication protocol as the standard communication protocol.Based on the high-performance NIO network framework Netty,combined with artificial intelligence technology,it designs and implements an access protocol standard,which is highly scalable,safer and more High-performance intelligent IoT cloud platform.The main work has the following aspects:1)Firstly,the research status of the Internet of Things communication protocol and the cloud platform is investigated,and the main problems faced in the construction of the cloud platform are analyzed and summarized.Introduce and analyze MQTT communication protocol and high-performance network framework Netty,research on the fusion technology of Internet of Things and artificial intelligence.2)A scheme of message encryption verification mechanism based on MQTT protocol is proposed,which can solve the problem of low message security in Internet of Things communication to a certain extent.3)The intelligent interface scheme of the Internet of Things cloud platform is proposed.The platform provides an interface based on the LightGBM intelligent prediction module,so that the MQTT message middleware can call this interface,and the corresponding message is sent according to the prediction result,so that the device has a certain self-learning ability,and provides a new idea for the intelligence of IoT devices.4)Completed the design and implementation of the cloud platform,and tested the functionality and performance of the built platform.The platform is divided into three major modules: MQTT message middleware,device management system,and intelligent interface module.After the test is completed,the results are analyzed and summarized.Figure 36;Table 21;Reference 56.
