Intelligent power-free key, access-control unlocking system and access-control unlocking method thereof

Abstract

The invention provides an access-control unlocking method. The method comprises the following steps: electric energy can be sent as an electromagnetic radiation form with real time by access control; an intelligent power-free key receives the electric energy with a preset distance from the access control so as to supply power to the intelligent power-free key; the intelligent power-free key obtains the user fingerprint image information and transits the information to the fingerprint information to-be-verified, a wireless signal containing the fingerprint information to-be-verified is emitted; the access control receives the wireless signal to obtain the fingerprint information to-be-verified, and the fingerprint information to-be-verified is compared with the preset fingerprint information pre-stored by the access control; if the preset fingerprint information is matched with the the fingerprint information to-be-verified, unlocking of the access control is carried out. The invention also provides the intelligent power-free key and an access-control unlocking system. an authentication mechanism of the access-control unlocking system has the advantages of safety, reliability and simple operation, when electric quantity of a battery of the intelligent power-free key is exhausted, user verification is still realized, and access control is unlocked, so that the access-control unlocking system has great convenience for an user.

Description

technical field [0001] The invention relates to a security unlocking technology, in particular to a power-free smart key and an access control unlocking system and an access control unlocking method applied to the power-free smart key. Background technique [0002] With the maturity of intelligent access control system technology, more and more high-tech is applied to the intelligent access control system and its supporting smart keys, such as radio frequency identification technology, biometric technology (such as fingerprint identification), making the smart key The functions are becoming more and more diversified. However, for the sake of safety, the smart key needs to undergo a series of security authentications. The authentication process is complicated and consumes a lot of power. When the battery of the smart key is exhausted, the smart key cannot authenticate, unlock and open the access control system. series of control actions, which will cause inconvenience to the...

Problems solved by technology

However, for the sake of safety, the smart key needs to undergo a series of security authentications. The authentication process is complicated and consumes a lot of power. When the battery of the smart key is exhausted, the smart key cannot authenticate, unlock and open the access control system. series of control actions, which will cause inconvenience to the user

In addition, traditional security authentication needs to set corresponding buttons or interface menus on the smart key to respond to the needs of users. During use, the user presses or touches the corresponding buttons or menus according to needs, and the operation process is relatively cumbersome.
