Abstract

The embodiment of the invention discloses a Modbus communication method and system based on an MQTT cloud platform. The method comprises the following steps: obtaining an MQTT client; acquiring an MQTT server; establishing an MQTT connection thread between the MQTT client and the MQTT server by the MQTT client; enabling the gateway to establish an MQTT thread, and establish an MQTT connection thread with the MQTT server; enabling the gateway to establish a Modbus thread and establish a Modbus connection thread with a Modbus bus, wherein the Modbus is connected with a Modbus device; wherein theModbus device is used for carrying out data transmission with the MQTT server and the MQTT client by the gateway; according to the embodiment of the invention, data transmission between the Modbus equipment and the MQTT client is realized by setting the gateway, namely remote acquisition control of the Modbus equipment is realized, other components are not needed, remote communication of the Modbus equipment is realized by only adopting the gateway and setting a connection protocol and a thread, the process is simple, the cost is low, and the development of intelligent control is facilitated.

Description

technical field [0001] The embodiment of the present application relates to the technical field of gateways, and in particular to a Modbus communication method and system based on an MQTT cloud platform. Background technique [0002] At present, in the field of intelligent control, most of them use wired control to realize device connection, mainly using traditional industrial control buses, such as PLC, BACNET, Modbus, lonwork, etc. If remote data collection or remote device control is required, other The process is cumbersome, and the host must be installed locally. In addition, a remote plug-in needs to be installed to complete the remote control collection function, which requires the use of a lot of components, making the cost very high, which is not conducive to the development of intelligent control. Contents of the invention [0003] The embodiment of the present application provides a Modbus communication method and system based on the MQTT cloud platform, so as t...
