Abstract

The invention discloses a data transmission method, which comprises the following steps that: when a first data message sent by a LoRa module is received, a central processing unit determines a firstsending module corresponding to the first data message; the central processing unit processes the first data message based on the data format corresponding to the first sending module; and sending theprocessed first data message to the first sending module, so that the first sending module sends the processed first data message to a terminal node in communication connection with the first sendingmodule. The invention further discloses a data transmission device and a computer readable storage medium. According to the invention, the data of the field device in communication connection with the LoRa module is transmitted to the terminal node in communication connection with the industrial Ethernet module or the field bus module, and because the transmission distance of the LoRa technologyis relatively long, long-distance and low-power-consumption data transmission is realized through the LoRa module.

Description

technical field

[0001] The present invention relates to the field of network technology, in particular to a data transmission method, device and computer-readable storage medium. Background technique

[0002] Electrical automation equipment has been widely used in industrial production processes. There are a large number of electrical automation devices, instruments and systems in many industrial sites, manufacturing workshops, automated logistics workshops, and transportation vehicle maintenance stations. These electrified equipment are usually distributed in various workshops of the factory, with a distance of several hundred to several kilometers. In order to ensure the safety of industrial production processes, the operating status of electrical automation equipment usually needs to be monitored.

[0003] The development of industrial Ethernet technology makes it widely used in the state monitoring of electrical automation equipment. Electrical equipment status monito...
