Description

Face recognition access control system with temperature sensing

This new model relates to an access control system; more specifically, it is a face recognition access control system through temperature sensing.

General corporate employees often use paper cards and clocking clocks for clocking in and out of get off work management for employees. When there are a large number of employees, the clocking process may cause personnel jams and confusion. Therefore, the development of personal identification card swipe sensor technology to replace The traditional way of punching in, in addition, the use of card sensing can also be used for personnel access control in specific places such as factories or construction sites, which can improve the efficiency and safety level of access control and absence control.

With the development of automation, in the access control management technology, each employee is generally issued an access control card. The entry process is that the user swipes the card with his personal access control card, and then the access control card machine verifies the legitimacy of the access control card and determines whether it is valid The registered access control card and whether it is an access control card within the validity period, when the verification is successful, the access control can be opened to allow users to enter and exit. Although this card swiping mode is convenient, it has a great risk because it only recognizes the card and only confirms that the access card is valid and legal, and cannot confirm whether the access card is owned by the current user. The access control management using the access control card has the risk that it can be lent or fraudulently used. From the above content, it can be seen that the access control management using the access control card only has the access control Manage security risks.

In this kind of access control, if you need to control the restriction that people with hyperthermia cannot pass the access control, you must send another person to use a temperature sensing instrument to confirm whether the person is in compliance, or directly use a forehead thermometer or ear thermometer to confirm .

The problem to be solved by the present invention is to provide an access control system, which can recognize a person's face while detecting the person's body temperature and then cooperate with the access control control to determine whether to pass or let go.
