Access control method and system

Abstract

The invention provides an entrance guard control method which comprises the steps that an entrance guard terminal broadcasts a wireless local area network connection invitation signal; a mobile terminal detects the wireless local area network connection invitation signal and establishes wireless local area network connection with the entrance guard terminal according to the signal; the mobile terminal acquires a door opening instruction and sends a first door opening request carrying a user account to the entrance guard terminal through the wireless local area network connection according to the door opening instruction; the entrance guard terminal checks the authority of the user account in response to the received first door opening request, sends an unlocking signal to a door locking device when the user account passes through the authority checking, generates an entrance guard control record, stores the entrance guard control record locally and / or uploads the entrance guard control record to a server in real time. The entrance guard control method provided by the invention is high in safe, low in cost and high in operation convenience. The invention also provides an entrance guard control system.

Description

technical field [0001] The invention relates to the technical field of computer control, in particular to an access control method and system. Background technique [0002] Access control refers to the control of the opening and closing of the entrance and exit of the house. At present, the access control method usually uses an access control terminal at the entrance and exit of the house, and the access control terminal controls the opening and closing of the entrance and exit. Access control terminals usually use on-site password verification, on-site biometric verification or specially-made access card on-site induction verification as the verification means to control the opening and closing of entrances and exits. [0003] However, in the current access control method, if the password verification method is adopted, the password is easily leaked or cracked, resulting in low security; if the biometric verification method is used, the access control terminal is required t...

Problems solved by technology

[0003] However, in the current access control method, if the password verification method is adopted, the password is easily leaked or cracked, resulting in low security; if the biometric verification method is used, the access control terminal is required to be equipped with a special biometric extraction device, which is costly. And it is inconvenient to use; if verification methods such as keys or access control cards are used, the keys or access control cards are easy to lose, resulting in the user being unable to pass the verification of the access control terminal
