A hidden card reader device for access control system

Abstract

The invention relates to the technical field of access control systems, in particular to a hidden card reading device for an access control system, comprising a casing, an inner cavity is arranged in the casing, a guide plate is fixed at one end of the casing, and one end of the guide plate is connected to the A card reading box is connected between the shells, a card reading cavity is arranged in the card reading box, a positioning cavity is communicated with the card reading cavity, a sliding baffle is arranged in the positioning cavity, and the baffle is One end abuts on the inner wall of the card-reading cavity, and the inner wall of the card-reading cavity is provided with a sliding card-reading device; the present invention controls the ejection of the card-reading device through the cooperation of the air pressure device and the slider device, so as to prevent other people from picking up the induction The door lock can be easily opened after the card is used to reduce the risk of other people's private access. At the same time, an alarm device and a forward and reverse switch of the power source are installed to prevent others from maliciously opening the door lock, thereby improving the security of the access control system.

Description

technical field [0001] The invention relates to the technical field of access control systems, in particular to a hidden card reader device for access control systems. Background technique [0002] As the name implies, the access control system is a system that controls the entrance and exit passages. It is developed on the basis of traditional door locks, and some users' access control systems use inductive card technology, which is to use the card reader to inductively identify the magnetic card, thereby Opening the entrance and exit is safer than traditional door locks. Although the proximity card is easy to carry, it is easy to lose. If other people pick up the proximity card, there is a risk of entering the channel without permission, reducing the security of the access control system. SUMMARY OF THE INVENTION [0003] The present invention provides a hidden card reading device for an access control system to solve the above technical problems. [0004] The above obj...

[0002] As the name suggests, the access control system is a system that controls the entrance and exit passages. It is developed on the basis of traditional door locks, and some users' access control systems use induction card technology, which is to use card reading equipment to identify magnetic cards by induction. Opening the entrance and exit is safer than traditional door locks. Although the proximity card is easy to carry, it is easy to lose. If other people pick up the proximity card, there is a risk of entering the passage without permission, which reduces the security of the access control system.
