Fingerprint identification device with cleaning function for attendance management system

Abstract

The invention relates to a fingerprint identification device with a cleaning function for an attendance management system. The device comprises a main body and a connection ring, wherein the main bodyis a cuboid; an identification system is arranged in the main body; a detection hole is arranged at one side of the main body; the connection ring is in the main body; an axis of the connection ringis vertical to the top of the main body; a cleaning mechanism and an auxiliary mechanism are arranged in the main body; and both the cleaning mechanism and the auxiliary mechanism are at the side, farfrom the top of the main body, of the connection ring and at the side, far from the detection hole, of the connection ring. The fingerprint identification device with the cleaning function for the attendance management system realizes a function of removing impurities on a glass disk through the cleaning mechanism so as to prevent impurities form affecting detection accuracy, and realizes a finger heating function through the auxiliary mechanism so as to make the finger sweat to prevent the finger from being too dry to affect collection of finger information.

Description

technical field [0001] The invention relates to the field of biological identification equipment, in particular to a fingerprint identification device with a cleaning function used in an attendance system. Background technique [0002] The so-called biometric technology is to use the inherent physiological characteristics of the human body (such as fingerprints, faces, irises, etc.) , voice, gait, etc.) to carry out personal identification, among them, the fingerprint time attendance machine is a kind of biometric equipment, which is a kind of equipment for identifying identity through fingerprints. [0003] During the use of the existing fingerprint attendance machine, the surface will be contaminated with more impurities, such as sweat stains, dust, etc., and the impurities will affect the accuracy of fingerprint recognition. Not only that, but when the fingers are too dry, the clarity of the fingerprint display will be reduced. Accuracy will also reduce the accuracy of f...
