Building door control system

Abstract

The present invention discloses a building door control system. The system comprises an IC card identification device, a biological identification device, a main control device, a detection device andan alarm device; the IC card identification device is used for identifying IC card information of a user and sending the IC card information to the main control device; the biological identificationdevice is used for identifying biological feature information of the user and sending the biological feature information to the main control device; the main control device is used for matching the ICcard information and/or the biological feature information with pre-stored user information, controlling a gate to be opened when matching succeeds and controlling the alarm device to work when matching fails; the detection device is used for acquiring moving information of the user in the gate within the preset time and sending the moving information to the main control device; and the main control device is also used for carrying out counting according to the moving information and controlling the alarm device to work when a counting result exceeds a preset threshold value. The safety protection coefficient of the door control system can be further improved.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a building access control system. Background technique [0002] With the general enhancement of social safety protection awareness, access control systems are widely used in office buildings, residential buildings and other buildings with excessive daily traffic. The access control system can quickly identify legal users and illegal users, ensure that legal users can enter and exit the building normally, and prevent illegal users from entering the building at will. [0003] However, the existing access control system has simple structure and single function, and can only identify legitimate users and illegal users by reading IC cards. When a legitimate user loses his IC card, it is impossible to guarantee that the legitimate user enters and exits the building normally; when an illegal user swipes the legitimate user's IC card to enter and exit the building, or when the...

[0003] However, the existing access control system is simple in structure and single in function, and often can only identify legal users and illegal users by reading IC cards

When a legitimate user loses his IC card, it is impossible to guarantee that the legitimate user enters and exits the building normally; when an illegal user swipes the legitimate user's IC card to enter and exit the building, or when the illegal user follows the legitimate user to enter and exit the building after swiping the card, it cannot prevent the illegal user from entering the building at will , also can not carry out the alarm reminder
