Wireless roaming connection method and system

The invention provides a wireless roaming connection method and system, and belongs to the technical field of wireless communication. According to the method, AGV equipment accessed to AP networking is used as networked AGVs, and the real-time position of each networked AGV is obtained; determining the moving direction of each networked AGV based on the real-time position of each networked AGV, and determining a roaming candidate AP corresponding to each networked AGV according to the moving direction of the networked AGV and the current position of the networked AGV; according to the method, the operation parameters of the to-be-selected roaming APs are obtained, the roaming target APs corresponding to the networked AGVs are determined according to the operation parameters of the to-be-selected roaming APs, the AGV can be matched with the optimal roaming AP, the roaming frequency is effectively reduced, network jamming caused by roaming is reduced, the packet loss rate is reduced, roaming is quicker, and mea
