Description

Technical Field

[0001] The utility model relates to the technical field of security access control, in particular to a weak current access control device for security. Background Art

[0002] The entrance and exit access control system refers to a system that controls entrance and exit channels and is used to provide channels for special groups of people. In recent years, with the development of sensing technology and biometric technology, the access control system has made great progress and entered a mature stage. There are now systems with various technologies such as induction card access control systems, fingerprint access control systems, iris access control systems, facial recognition access control systems, and random keypad access control systems. The application areas of access control systems are becoming wider and wider.

[0003] Publication number: CN 116798156 A proposes a low-voltage access control device for security based on the Internet of Things. In this case, through the setting of a blocking component, when there is a person following the user, the control panel will control the cylinder to open. After the cylinder is opened, it will push the movable shaft. The movable shaft extends from the surface of the socket block, and the other side of the movable shaft is against the surface of the left blocking plate to prevent the following person from crossing the threshold. Through the coordinated use of the cylinder and the movable shaft, the effect of ensuring that the user must use fingerprint recognition to pass is achieved, avoiding the problem of affecting the authentication function of the access control device. However, in actual application, the length of the partition is fixed, which makes the access control device unable to meet the barrier requirements for channels of different widths and can only be used once, reducing the applicability of the device. Therefore, it is necessary to propose a low-voltage access control device for security to solve the above problems. Utility Model Content
