Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0032] The public protocol Internet of Things platform and device access method adopts eMQTT based on the MQTT communication protocol (eMQTT is a scalable, fault-tolerant and scalable MQTT message server developed using Erlang / OTP) message middleware, and EMQTT message middleware uses The cluster mode is deployed on server nodes, and the synchronization of messages is kept between server nodes; it also includes database, Redis database and HTTPS (Hyper Text Transfer Protocol over Secure SocketLayer, network protocol) protocol message access interface, and the HTTPS protocol message access interface uses HTTPS The request is adapted to the MQTT protocol; at the same time, the Nginx ...

Abstract

The invention discloses a public protocol Internet of things platform and a device access method. The public protocol Internet of things platform uses eMQTT message-oriented middleware based on an MQTT communication protocol, the EMQTT message-oriented middleware is deployed on server nodes in a cluster mode, and message synchronization is maintained among the server nodes. A database, a Redis database and an HTTPS protocol message access interface are also included. The HTTPS protocol message access interface adapts an HTTPS request to an MQTT protocol. The server nodes are deployed with a load balancing service, a device access service, a device management service, and a theme authority management service. Each service carries out communication through an RESTful API interface. By usingthe public protocol Internet of things platform and the device access method, the bidirectional authentication between a device end and a server side is realized, and the association between a certificate user and the theme authority of publishing subscription is also realized. At the same time, adaption to the MQTT protocol is implemented, and the controllability of a device access authority anda data transmission authority, and the safety of a data encryption transmission channel are ensured.

Description

technical field [0001] The invention relates to the technical field of computer Internet of Things, in particular to a public protocol Internet of Things platform and a device access method. Background technique [0002] The MQTT (Message Queuing Telemetry Transport) protocol is designed for lightweight publish-subscribe message transmission, aiming to provide reliable network services for IoT devices in low-bandwidth and unstable network environments. Its core design philosophy is open source, reliable, lightweight, and simple. It can maintain long connections and realize two-way transmission of messages. It has become a general protocol for the Internet of Things. [0003] Nowadays, the access of IoT devices in various industries generally uses private protocol access, and different types of devices need to be individually adapted, which increases the complexity and workload. At the same time, in the scenario where the device uses HTTP to report data, there is a problem o...
