Signal-to-noise ratio measurement method and system for high-speed industrial communication system

The invention relates to a signal-to-noise ratio measurement method for a high-speed industrial communication system. The high-speed industrial communication system is mainly used for solving the problems that a traditional bus on an industrial site is low in bandwidth, real-time and non-real-time cannot be borne at the same time, and the network structure is complex. The high-speed industrial communication system can support IPV6 address communication, time-triggered industrial control communication, TSN and safety mechanisms such as a white list, deep detection and data encryption. The invention also relates to a signal-to-noise ratio measurement system for the high-speed industrial communication system. According to the signal-to-noise ratio measurement method and system for the high-speed industrial communication system disclosed by the invention, the signal-to-noise ratio estimation of the channel can be simply and effectively obtained, so that the signal transmission quality from the user node to the re
