Offline access control management system and offline access control management method

Abstract

The invention discloses an offline access control management system and an offline access control management method. The offline access control management system comprises card reading equipment and door control equipment, wherein the card reading equipment is in communication connection with the door control equipment and is used for reading an enciphered message from a detected door control cardfor decrypting to obtain card checking information corresponding to an access control card and transmitting the card checking information to the door control equipment; the door control equipment isused for receiving the card checking information and detecting whether a first check code is matched with a locally-stored second check code or not according to a card number in the card checking information; when the second check code is matched with the first check code, the door control equipment controls the door control to be opened, updates the second check code, generates check code information corresponding to the updated second check code and transmits the check code information to the card reading equipment for enabling the card reading equipment to update the first check code according to the check information. The offline access control management system and the offline access control management method disclosed by the invention can identify the door control card under the offline condition and is wide in application range.

Description

technical field [0001] Embodiments of the present invention relate to access control technology, and in particular to an off-line access control management system and an off-line access control management method. Background technique [0002] With the popularization of security access control, access control system is more and more widely used. At present, the management of access control cards in most access control systems is completed online. Specifically, the access controller of the access control system needs to be connected online to the background management terminal of the access control system in order to perform data transmission with the background management terminal. Determine whether the detected access control card can open the access control device. However, in some special environments, the access control controller cannot communicate with the background management terminal online. For example, due to the environmental conditions of the old residential are...

AI Technical Summary

Problems solved by technology

However, in some special environments, the access control controller cannot communicate with the background management terminal online. For example, due to the environmental conditions of the old residential area, the access control controller cannot communicate with the background management terminal. Unable to identify and manage the access control card

It can be seen that the existing access control controller realizes the identification and management of the access control card based on the background management terminal of the online connection, and its scope of application is limited by the wiring environment, and there is a problem of narrow application range
