Problems solved by technology
However, in practical applications, fingerprints are often not recognized by the access control system due to factors such as irregular movements when collecting fingerprints, foreign objects on the surface of the finger, sensor aging, and changes in the external temperature environment, resulting in authentication failures.
Also, trespassers may try to verify fingerprints, but there are no alarms on site to alert of possible trespasses, and there is no good way to track trespassers

The invention discloses an access control system, and relates to the technical field of safety protection. The access control system comprises a central control module, a fingerprint collection module, a face photographing module, a FLASH memory module, a door opening and closing driving module, a safe alarming module, a network interface module, a main control module, a third-party secondary management module and a power module. According to the access control system, fingerprint verification and face verification are combined, and therefore the safety is greatly improved; meanwhile, a multiple real-time managing technique is adopted, and therefore multistage management is convenient; automatic real-time log recording and multiple log backup are achieved, tracing is convenient, and multistage monitoring linkage is achieved in alarming; the access control system is low in cost and can be applied and popularized in a large scale.
Description
technical field [0001] The invention relates to the technical field of safety protection, in particular to an access control system. Background technique [0002] Banks are the main components of the country's financial system. With the continuous growth of the banking industry, bank security has been paid more and more attention by people from all walks of life, and the access control system of the bank vault door is its top priority. Therefore, the access control management of the bank vault door has become an important topic in front of every security personnel. Similarly, places that require important management such as arsenals also need access control systems for security protection. The application of advanced computer network technology, communication technology and biometric identification technology has enabled the rapid development and continuous improvement of access control system technology. Coupled with the uniqueness and high anti-counterfeiting of biometric...
