An access control system based on two-dimensional code

Abstract

An access control system based on a two-dimensional code, including a mobile terminal and an access control system, the mobile terminal includes a resident terminal, the access control system includes an access control two-dimensional code, a system server, and an access control switch, and the access control switch is connected to the system server through a network; In addition, the mobile terminal also includes a visitor terminal and a security terminal; the resident terminal includes an account number generation request sending unit and an access control request acknowledgment unit, and the visitor mobile terminal includes a visitor two-dimensional code receiving unit and a visitor two-dimensional code display unit, and the security terminal includes Two-dimensional code scanning and access control request issuing unit; its beneficial effect is that the use of two-dimensional codes for access control identification can make the access control system simply, quickly and comprehensively record personnel entry and exit information; for unrecognizable two-dimensional codes, it can prohibit entry and exit or alarm; Visitors can also quickly generate and record their entry and exit information, which can effectively improve the safety management effect of the community and reduce the workload of security personnel.

Description

technical field [0001] The invention relates to the technical field of access control systems, in particular to an access control system based on two-dimensional codes. Background technique [0002] With the improvement of living standards, people have put forward higher requirements for the living environment, and the security system of residential quarters has attracted more and more attention. Access control management is an important part of community safety management. Existing access control systems include out-of-sequence keyboard methods, card identification methods, biometric identification methods, and the like. The keyboard of the random keyboard method is fixed on the door, and the user is easy to leak the password when entering the password; the security of the card identification method is also very poor, only the card is recognized but not the person, it is easy to copy, there is no personal identity information in the card, and visitors enter and exit the doo...

AI Technical Summary

Problems solved by technology

The keyboard of the random keyboard method is fixed on the door, and the user easily leaks the password when entering the password; the security of the card identification method is also very poor, only the card is recognized but not the person, it is easy to copy, there is no personal identity information in the card, and visitors enter and exit the door Without systematic tracking, security guards need to manually check and record information, the work is complicated and the security is low; the safety factor of the biometric identification method is high, but the cost is high, and the identification rate is not high, and slight changes in the biological itself will affect the identification effect, so it is not suitable mass promotion
