Abstract

The invention discloses a variable code modulation method for a high-speed industrial communication system based on an OFDM system, a terminal, electronic equipment and the system, and the method comprises the steps: obtaining a transmission environment parameter; if it is determined that the change of the acquired transmission environment parameter exceeds a preset threshold range compared with the original transmission environment parameter, re-selecting a coding mode and / or a modulation mode according to the acquired transmission environment parameter; and processing the data by using the determined data coding mode and / or modulation mode. The high-speed industrial communication system is mainly used for solving the problems that a traditional industrial field bus is low in bandwidth, cannot bear real-time and non-real-time at the same time and is complex in network structure. The high-speed industrial communication system can support IPV6 address communication, time-triggered industrial control communication, TSN, white list, deep detection, data encryption and other security mechanisms.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a variable coding and modulation method, terminal, electronic equipment, and the OFDM-based system for high-speed industrial communication systems based on OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) High-speed industrial communication systems. Background technique [0002] At present, the industrial bus system adopts single-carrier modulation or baseband modulation, and the coding modulation method is fixed. [0003] The inventors of the present application have found that the transmission distance of high-speed industrial communication systems usually changes with the actual application, and the transmission media used are different, and the amount of data transmitted is constantly increasing; The encoding and modulation method will affect the data transmission effect. Contents of the invention [0004] An embodim...
