The access control system is the entrance and exit control system. It is a system that controls the entrance and exit passages. The functions of the access control system include access authority management, access control recording function, real-time monitoring function, abnormal alarm function, etc. Nowadays, various communities, campus dormitories, and families And so on all adopt various electronic access control systems to protect security.

At present, the commonly used access control system is the fingerprint access control system, but there are certain disadvantages in the ordinary fingerprint access control system. The fingerprint identification method commonly used in the market is optical fingerprint, which can only scan the surface of the finger skin, and what it collects is only a plane picture. , the system has the following disadvantages: higher requirements on the environment, clear fingerprint path is required, artificial fingers such as "fingerprint sleeves" are easy to get away with it, and the texture cannot be affected by slight influences, such as the fingerprint on the finger is smoothed or the fingerprint on the finger There are too many wrinkles and frequent changes or peeling on the fingers, etc. For such fingerprint recognition, the error rate is high and the rejection rate is high. In some occasions where there are many people, sometimes people swipe their fingerprints many times before being recognized, which affects the efficiency of entering the door. It leads to queuing up and wasting everyone's time. Furthermore, the access control system cannot be used during a power outage, and the monitoring room cannot control the gate. people's normal life.

Utility model content

The technical problem solved by the utility model is to provide a non-contact 3D fingerprint access control system for the deficiencies of the current technology.
