Data concentrator acquisition control method based on MQTT (Message Queuing Telemetry Transport), data concentrator acquisition control device based on MQTT and data concentrator acquisition control system based on MQTT

Abstract

The invention discloses a data concentrator acquisition control method based on MQTT (Message Queuing Telemetry Transport), a data concentrator acquisition control device based on MQTT and a data concentrator acquisition control system based on MQTT. The method comprises the following steps of connecting an MQTT server; performing theme subscription according to predefined parameters; and forwarding commands by virtue of the MQTT server, thereby further realizing acquisition and remote control. The device comprises a server connection unit, a theme subscription unit and an instruction execution unit. The system comprises the MQTT server, a sensor, an actuator, a concentrator, a data acquisition client and a remote acquisition client. By virtue f the MQTT protocol and the theme subscription mechanism, various communication demands among terminals are realized, real-time acquisition and remote control of the data concentrator can be realized conveniently, and the problem of inadequate IP (Internet Protocol) address resources in common network communication is effectively solved. By virtue of an MQTT frame, the system structure complexity can be effectively reduced, the expandability, stability and real-time property of the system are enhanced, the bandwidth is saved, and the expenditure is reduced. The method, the device and the system can be widely applied to the internet of things.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an MQTT-based data concentrator acquisition control method, device and system. Background technique [0002] With the increasing development of the Internet of Things, various sensors and actuators will be spread in every corner of the real world, forming a huge control network. How to efficiently collect data from a large number of sensors and actuators in real time and perform remote control is an important problem currently facing. [0003] However, today's Internet of Things communication does not have a uniform and efficient protocol or standard. Although many commonly used protocols such as http, smtp, ftp, etc. can handle communication problems between devices, they are prone to the problem of insufficient IP address resources. As a result, the terminals cannot communicate with each other. [0004] MQTT (Message Queuing Telemetry Transport): Message Queuin...

[0003] However, today's Internet of Things communication does not have a uniform and efficient protocol or standard. Many commonly used protocols such as: http, smtp, ftp, etc. can handle communication problems between devices, but they are prone to the problem of insufficient IP address resources. As a result, the terminals cannot communicate with each other
