Anti-passback method, device and system

Abstract

The embodiment of the present invention discloses an anti-passback method, device and system. A plurality of access control controllers communicate with a server. After the access control controller successfully reads the identification of the access control card by the monitoring card reader, The identification of the card reader and its own identification are sent to the server; the server searches for the identification of the card reader that read the access control card last time, and the identification of the access control controller corresponding to the card reader, and determines the route corresponding to the door opening request; When the determined route exists in the preset route list, the server sends an instruction to open the door to the access controller. The route list can include routes between doors controlled by multiple access controllers. When the user swipes the card reader on any door with the access card, the access controller controlling the card reader will pass the information to the server , the server judges whether to allow passage according to the set route list. It can be seen that this solution realizes the anti-passback function in multiple access controllers.

Description

technical field [0001] The invention relates to the security field, in particular to an anti-passback method, device and system. Background technique [0002] Anti-passback is a function of the access control system. For example, anti-passback may include in-out anti-passback and route anti-passback. The anti-passback system for entering and exiting requires cardholders to swipe their cards to come in from a certain door, and must swipe their cards to exit through a certain door, and the card swiping records must strictly correspond to one entry and one exit. The route anti-passback requires the card holder to swipe the card to enter from a certain door, and must follow the preset route to swipe the card to go out from the door corresponding to the route. [0003] Existing anti-passback schemes are generally implemented through access controllers: the access controller is configured with a list of routes between several doors under the control of the access controller, whi...

AI Technical Summary

Problems solved by technology

[0004] However, since the access controller can only manage a few doors, and the route list configured in the access controller is only the routes between the few doors, this solution can only be controlled by the access controller. Implement anti-passback between a handful of gates

[0005] If there are multiple access controllers in a large office building, the above solution cannot realize the anti-passback function in the entire office building
