Automatically configured Internet of Things system based on MQTT protocol

Abstract

The invention provides an automatically configured Internet of Things system based on an MQTT protocol. The system comprises a cloud server, an Internet of Things gateway and industrial equipment, wherein the industrial equipment supports a first network communication protocol; the Internet of Things gateway can realize conversion between the first network communication protocol and the MQTT protocol, data transmission with industrial equipment through the first network communication protocol is realized; data transmission with a cloud server is realized through an encrypted MQTT protocol, namely, automatic configuration between equipment information of industrial equipment and an MQTT protocol topic is realized through an Internet of Things gateway, manual intervention is not needed, useby a client is facilitated, and manpower configuration and later maintenance cost are saved; and the data transmission security is high, and the security of client data is ensured.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to an automatic configuration Internet of Things system based on the MQTT protocol. Background technique [0002] With the increasing development of the Internet of Things technology, more and more industrial equipment needs to be connected to the network and controlled by the cloud. In order to access the Internet of Things, the commonly used solutions are: 1. Develop new products with IoT functions; 2. Develop dedicated gateways for old devices. [0003] Among them, newly developed products with Internet of Things functions often need to support a variety of popular access network methods: such as Wi-Fi, Bluetooth, GPRS, 3G, 4G, eMTC and NB-IoT, etc., and when the product is updated Finally, the old products will not be able to access the network, which will inevitably cause a waste of social resources and an increase in cost; and the dedicated gateway developed for the old ...

Problems solved by technology

[0003] Among them, newly developed products with Internet of Things functions often need to support a variety of popular access network methods: such as Wi-Fi, Bluetooth, GPRS, 3G, 4G, eMTC and NB-IoT, etc., and when the product is updated Finally, the old products will not be able to access the network, which will inevitably cause a waste of social resources and an increase in cost; and the dedicated gateway developed for the old equipment can be configured by the end user (equipment user) to connect the equipment to the Internet of Things. However, the existing IoT gateway requires complex configuration when connecting devices, which not only increases the difficulty of maintenance, but also makes the configuration error-prone, and increases maintenance and labor costs

[0004] At the same time, when conventional technology accesses the network, it often uses a variety of different network protocols to connect, and the protocols used by various manufacturers are also different. The corresponding IoT gateway needs to be compatible with different protocols, which makes the development of cloud servers more difficult. Cloud servers have higher requirements

In addition, the existing products on the market pay more attention to the diversity of their functions, while ignoring the security of network data. They often use simple connections based on TCP or UDP for data transmission, which may cause heavy losses to customers.
