Kind Code:
A1
Abstract:
A data link construction method and apparatus for an access control system, and a computer device and a computer storage medium. The method comprises the steps of: obtaining a system-wide device address table of the access control system (step S101); obtaining terminal information of a plurality of target terminals according to the system-wide device address table (step S102); writing the terminal information of the plurality of target terminals into an NAT routing post-stage device table of the target terminals (step S103); and constructing a point-to-point data link among the target terminals according to the NAT routing post-stage device table (step S104). Therefore, a mesh network data link topological structure among the terminals is automatically constructed without depending on a platform center server, all the terminals can directly communicate with one another by point-to-point crossing routing, and the load of the platform center server of the access control system is reduced.
