Abstract

The invention provides an access control system with inlet and outlet dynamic opening passwords. The access control system comprises an access controller and mobile terminals; the access controller comprises a password generating module, an encryption module, a two-dimension code generating module, and a LCD screen; each of the mobile terminal is provided with a decryption module. According to an application method, random passwords are generated by the password generating module; the encryption module is used for encryption of the random passwords; the two-dimension code generating module is used for converting the encrypted random passwords into two-dimension codes; the LCD screen is used for displaying the two-dimension codes; the mobile terminals are used for scanning the two-dimension codes; and the decryption modules are used for decryption of the two-dimension codes so as to obtain passwords. The access control system is simple in structure; it is not necessary for passers to remember the passwords, a situation that passers may be unable to pass the access control system because of forgetting the passwords is avoided, artificial password leakage is avoided, and passing safety of the access control system is improved.

Description

technical field [0001] The invention belongs to the technical field of access control, in particular to an access control system for realizing a dynamic code for opening an entrance and exit. Background technique [0002] The access control controller (hardware device) or the access control management system (software) can only provide a fixed password for opening the door, and the passerby can enter and verify the password on the password keyboard connected to the access controller to achieve the purpose of opening the door. This method has the following problems: [0003] 1. The password is fixed. In order to ensure its security, it needs to be changed regularly. After changing the password, passers-by need to be notified manually. [0004] 2. Passwords are not easy to keep, rely entirely on memory, and are easy to leak. Contents of the invention [0005] The purpose of the present invention is to provide an access control system with a simple structure that realizes t...
