User node discovery method and device, electronic equipment and storage medium

The invention provides a user node discovery method and device, electronic equipment and a storage medium. The method is used for an AutBus bus of a high-speed industrial communication system, the high-speed industrial communication system is mainly used for solving the problems that a traditional bus in an industrial field is low in bandwidth, cannot bear real-time and non-real-time at the same time and is complex in network structure, and the high-speed industrial communication system can support IPV6 address communication, can support time-triggered industrial control communication. TSN can be supported, and security mechanisms such as white list, deep detection and data encryption can be supported. The method comprises the following steps: broadcasting parameters of an access channel of the AutBus, wherein the parameters of the access channel comprise an access probability; receiving an access application sent based on the parameters of the access channel from the user node; determining whether the access
