Passive electronic lock core, passive electronic key, code manager and key manager

Abstract

The invention relates to a passive electronic lock cylinder and a passive electronic key, both of which adopt electronic password recognition and additionally, a password manager which manages the electronic password and a key manager which manages the electronic key. The strength of the electronic password is more than 4 billion groups of random combination; the electronic password is provided with the function of guarding against electronic technique cracking; theoretically, the duration of continuous electronic brute force cracking is more than 180 days. A mini generating plant, which can provide the required electric energy for the operations of checking password, unlocking and the like, is positioned in the electronic lock cylinder. The electronic key can store the passwords of a plurality of electronic lock cylinders (typical value: 63). The electronic key is provided with operating functions like updating, duplicating and cleaning up the electronic password, initializing and cloning the key and the like; besides, the electronic key provides a two-level user management method which consists of a privilege password (unlocking and handling password) and a common password (unlocking only). The electronic lock cylinder can be used for directly replacing most mechanical pin tumbler lock cylinders (restrictive to minimum volume).

Description

technical field [0001] The invention relates to a lockset, especially a passive electronic lock core, a passive electronic key, a password manager and a key manager using electronic password identification. Background technique [0002] As a protective item, locks are indispensable office and daily appliances in people's modern life, and the lock cylinder is the core component of the lock, which plays a vital role in the performance of the lock. At present, there are two main types of lock cylinders on the market: mechanical pin lock cylinders and active electronic lock cylinders, among which mechanical pin lock cylinders are the most widely used. [0003] Although the mechanical pin lock cylinder has a wide variety of realization forms and great differences in performance, its basic principle is that multiple groups of two pin pins supported by springs are set in the hole between the inner and outer lock cylinder walls, and they are located in the inner lock cylinder. 1.
