Access control method and system, electronic lock, and management and visitor terminal

Abstract

The invention discloses an access control method and system, an electronic lock, and a management and visitor terminal. A management terminal authorizes the access of a legal visitor terminal to an electronic lock. Then the management terminal will send the identification number of the visitor terminal, access time, and access secret key to the electronic lock. When the electronic lock detects the access request from the visitor terminal, the access request carries with the identification number of the visitor terminal and current access secrete key, the electronic lock will judge whether the visitor terminal is a legal visitor terminal that has been authorized by the management terminal or not according to the identification number, thus the access secret key will not be stolen and used by other visitor terminals, the happening of illegal access to the electronic lock is avoided; moreover, the management only authorize a certain time period during which the visitor terminal can access the electronic lock, after the period, the secret key expires, and thus the access safety of the electronic lock is further improved.

Description

technical field [0001] The present invention relates to the field of security technology prevention, and more specifically relates to an access control method and system, an electronic lock, a management terminal and a visitor terminal. Background technique [0002] At present, the electronic lock with anti-theft alarm function has replaced the traditional mechanical lock, which avoids the potential safety hazard caused by the imitation of the key. Moreover, the electronic lock only needs to remember a set of passwords and does not need to carry metal keys, which saves people The trouble of carrying metal keys has been widely used in people's life and work. [0003] However, because existing smart door locks, car locks, etc. are made by combining electronic technology, integrated circuit design, a large number of electronic components and biometric technology, the cost is very high; , once the unlocking password is stolen, it will cause great losses such as property for its...
