Electronic password lock system and control method thereof

Abstract

The invention relates to an electronic password lock system and a control method thereof. The system mainly comprises a password lock host, an unlocking handset and an upper computer. An unlocking action is limited and protected by virtue of two authorities, namely dynamic passwords and biological fingerprint features; the operation process of a normal unlocking operation is as follows: transmitting unlocking passwords and operator number to the handset by virtue of the upper computer, granting a using permission to an operator by reading the fingerprint features by virtue of the handset, transmitting the passwords to the password lock host by operating keys on the handset by virtue of the operator through a radio signal so as to realize unlocking, then manually locking, transmitting a return code to the handset by virtue of the password lock host through radio transmission, returning the return code, lock status information and the like to the upper computer by virtue of the handset, and saving work records of the lock in a computer by virtue of the upper computer. The passwords are invisible to the operator during the entire unlocking process. By virtue of the handset and the password lock host, an alarm hint is displayed and the system is locked if errors occur frequently during fingerprint or password recognition process.

Description

Technical field [0001] The invention relates to an electronic code lock system matched with equipment such as safes and cabinets in the financial industry and a control method thereof. Background technique [0002] With the advancement of society, technology, and culture, the safety of mechanical locks has become less and less able to meet the needs of various industries. At this time, electronic locks came into being. At present, the electronic lock has developed to the technical level of remote unlocking, which brings great convenience to the operation. Common remote control electronic anti-theft locks mainly include optical remote control and radio remote control. Optical remote control uses a narrow-angle optical transmission password. The advantage is that the amount of information transmitted can be very large, the speed is extremely fast, and the human eye cannot recognize it, and it cannot use the instrument to capture the signal to try to copy on the optical path, so th...
