Internet of Things equipment data transmission method based on MQTT protocol

Abstract

The invention specifically relates to an Internet of Things equipment data transmission method based on an MQTT protocol, and the method comprises the steps: carrying out the registration of Internet of Things equipment needing to be accessed, and generating a corresponding data transmission authority based on the MQTT protocol; configuring a corresponding data transmission authority and associated equipment based on the service attribute of the Internet of Things equipment to generate a corresponding data transmission rule engine; acquiring corresponding sample data based on the data transmission authority of the Internet of Things equipment; performing logic verification on a data transmission rule engine of the Internet of Things equipment based on the sample data, and optimizing the corresponding data transmission rule engine based on a logic verification result; and after the verification is passed, generating a corresponding data transmission relation graph based on the data transmission rule engine of each piece of Internet of Things equipment. According to the data transmission method for the multiple Internet of Things devices, the effectiveness of a data transmission rule engine between the devices and the accuracy of data transmission logic can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of the industrial internet of things, in particular to a data transmission method of an internet of things device based on the MQTT protocol. Background technique [0002] With the continuous development of IoT technology, more and more IoT devices need to be connected to the network and controlled by the cloud. In terms of IoT communication protocols, the MQTT (Message Queuing Telemetry Transport) protocol has emerged. Due to the advantages of simplicity, light weight, easy implementation and its publish / receive based message forwarding model, the MQTT protocol has gradually become a standard communication protocol between IoT devices. [0003] Among them, the Chinese patent with publication number CN110855774A discloses an "Internet of Things System for Automatic Configuration Based on MQTT Protocol", which includes a cloud server, an Internet of Things gateway and industrial equipment, wherein the indust...

Problems solved by technology

However, due to customers' limited understanding of the business attributes of IoT devices, the configured data transmission rule engine is prone to logic errors or circular logic problems, which in turn leads to poor effectiveness of data transmission rule engines between IoT devices and confusion in data transmission logic
