Abstract

The invention discloses a door access anti-following system and method. The door access anti-following system comprises a first information identifier, a first door access controller, a second information identifier, a second door access controller, at least one camera, a camera controller, a main controller, a first door and a second door; a door access protection region communicates with the external through a channel; the first door and the second door are adjacent to each other, the first door, the second door and a channel surrounding region are the detection region; at least one camera is used for shooting a real-time image in the detection region, the area of the detection area is less than or equal to a preset value, the first door access controller and the second door access controller are respectively used for controlling the open and close of the first door and the second door. Through the technical scheme provided by the embodiment of the invention, one person can pass thedoor access to enter the door access protection region through the same door access information, and the following phenomenon is avoided.

Description

technical field [0001] The embodiment of the present invention relates to an access control anti-tailgating technology, in particular to an access control anti-tailgating system and method. Background technique [0002] The access control system is an effective measure to realize security management at the entrance and exit of the access control protection area. It is widely used in the protection of various important sites, such as the maintenance operation platform of the catenary of the train station. [0003] After the catenary of the train station is powered off and hangs the pole, maintenance personnel need to enter the maintenance work platform to overhaul the roof. To ensure the safety of the train, an access control system is installed at the entrance of the maintenance work platform. A conventional access control system includes a door and an access control host. The access control host can identify the access control information and control the opening of the door...
