Abstract

The invention belongs to the related technical field of MQTT transmission protocols, and discloses a method for connecting an industrial acquisition module with an MQTT cloud server. The method comprises the following steps: (1) performing connection compiling on a logic program to generate a static library; (2) compiling a user program and the static library link to generate an HEX file, and downloading the HEX file into an acquisition module by using a serial port; (3) initializing an authentication parameter of the MQTT server by the acquisition module, and sending an access authenticationrequest through the wireless communication module to connect the MQTT server; (4) publishing the data information acquired in real time by the acquisition module to a predetermined theme of the MQTT server, and forwarding the published information to a client subscribing the predetermined theme by the MQTT server; meanwhile, subscribing to the theme by the acquisition module and sending the information under the corresponding theme to the acquisition module by the MQTT server. According to the invention, the applicability and the flexibility are improved.

Description

technical field [0001] The invention belongs to the technical field related to the MQTT transmission protocol, and more specifically relates to a method for connecting an industrial collection module to an MQTT cloud server. Background technique [0002] At present, the emergence of new technologies such as big data, smart factories, and cloud computing heralds the arrival of a new era. In the field of industrial control, the R&D, production, and maintenance methods of traditional industrial sites appear to be limited and closed. The cost of manual operation and maintenance alone is too high and the production efficiency is not high. It is easy to make mistakes when processing more and more production data, and Failures cannot be dealt with in a timely manner. [0003] The MQTT protocol is a TCP / IP-based application layer communication protocol developed by IBM. It has the advantages of light weight, open source, low power consumption, and low traffic. It is usually suitabl...
