Abstract

A data sending and receiving method, a data sending and receiving system, a storage medium and a data sending and receiving terminal, wherein the data sending method comprises: converting a variable name with physical properties into a numerical value, and the numerical value embodies the Physical attribute; encapsulate the value and the variable value corresponding to the variable name into a data packet and send it together. The present invention can avoid the problem of data mapping dislocation occurring during engineering implementation.

Description

technical field [0001] This article relates to network data transmission technology, especially a data transmission and reception method, a data transmission and reception system, a storage medium and a data transmission and reception terminal. Background technique [0002] With the continuous expansion of production scale, the scale and number of devices in the process industry continue to increase, and control tasks generally require multiple control stations, such as Distributed Control System (DCS) and Safety Instrumented System (SIS) , completed together. Data sharing between control stations is generally achieved through Ethernet, such as figure 1 As shown in the figure, a physical network is formed by connecting multiple control stations to the same switch. On the basis of the physical network, a point-to-point logical link between the two control stations is established with the help of network protocols (usually Transmission Control Protocol TCP / Internet Protocol I...
