Embodiment Construction

[0023] Such as figure 1 As shown, the unlocking control device of the fingerprint lock includes a fingerprint lock controller 1 and a fingerprint sensor 2, and the fingerprint sensor 2 transmits fingerprint information to the fingerprint lock controller 1, and is characterized in that: the fingerprint lock controller 1 adopts DSP as the control The fingerprint lock controller 1 is provided with a light-emitting diode 3 indicating the working state of the fingerprint lock controller; the fingerprint sensor 2 is provided with a protective cover 4 that can wake up the fingerprint lock controller in a sleeping state when it is opened; Also be provided with programmer 5 and fingerprint collector 6 in described control device, fingerprint collector 6 passes the fingerprint information of all related personnel to programmer 5, and programmer 5 stores the fingerprint information of setting and opening fingerprint lock into fingerprint lock Controller 1.

[0024] The programmer 5 adop...

Abstract

The invention discloses an unlocking controller of a fingerprint lock and a multi-person series unlocking method. The unlocking controller comprises a fingerprint lock controller and a fingerprint sensor. The unlocking controller is characterized in that a light emitting diode for indicating the work state of the fingerprint lock controller is arranged on the fingerprint lock controller, a protective cover capable of awakening the fingerprint lock controller is arranged on the fingerprint sensor, a programmer and a fingerprint collector are also arranged in the unlocking controller, the fingerprint collector sends the fingerprint information of all relevant personnel to the programmer, and the programmer sets the fingerprint information for unlocking the fingerprint lock and storing the fingerprint information into the fingerprint lock controller. The invention changes the traditional method of storing the fingerprint of all relevant personal into the fingerprint lock controller, and greatly improves the confidentiality of the fingerprint. Because the unlocking sequence of the unlocking personnel can be limited, the fingerprint lock is safer and more reliable. Because a template matched pulse coupling neural network thinning algorithm is adopted, and the invention is realized on a DSP control platform, the fingerprint identification accuracy and the identification efficiency are improved.

Description

technical field [0001] The invention relates to a fingerprint lock, in particular to an unlocking control device for a fingerprint lock and a method for multiple people to unlock in series. Background technique [0002] Fingerprint identification technology is one of the relatively complete identification methods in biometrics at present, and has been widely used in access control systems, attendance systems and other fields. At present, the fingerprint locks that use fingerprints as the unlocking mark can realize the function of unlocking with a single fingerprint independently, and realize fingerprint information management on the fingerprint lock. But these fingerprint locks have the following disadvantages: [0003] In terms of fingerprint information management, the function of collecting fingerprints is integrated into the fingerprint lock. In this way, once the fingerprint lock is damaged by external force, take out the chip in it, and it is possible to obtain all th...
