Description

TECHNICAL FIELD

[0002] With the rapid development of science and technology, the access control system has gradually evolved from the traditional mechanical lock to the intelligent, safe, convenient high-tech product; the intelligent access control system realizes the remote control and management of the access control equipment through electronic technology, biological identification technology, RFID technology, password setting and other means, so as to achieve the purpose of safe management and intelligent management; among them, the biological identification technology becomes one of the most critical technologies in the intelligent access control system due to its uniqueness and irreproducibility.

[0003] The biological identification and password double verification access control machine identifies the biological characteristics of the user through the biological identifier, compares it with the information stored in the database, confirms the identity, and then requires the user to input the password for secondary verification; only when the biological characteristics and the password are both verified, the access control system will allow the user to enter; this double verification mechanism greatly improves the security and reliability of the access control system.

[0004] At present, most of the intelligent access control machines on the market have the function of biological identification and password double verification, but when using this kind of access control machine, because its bottom generally adopts hollow pipe parts for support, the inside of the hollow pipe can be used for cable passing through, but when the top end of the hollow pipe is directly fixed on the shell of the access control machine, when the parts inside the access control machine need to be disassembled and repaired, the cable will be completely stuck in the hollow pipe part and cannot be pulled out to a suitable distance, which will cause the parts inside the access control machine to be repaired only in the shell part of the access control machine, and the shell will block the internal parts, which is not conducive to moving the internal parts outward to a relatively open part for repair operation, which affects the convenience of repair operation. In view of this, we propose a biological identification and password double verification access control machine. TECHNICAL FIELD
