Fingerprint identification attendance equipment based on Internet of Things

Abstract

The invention relates to the technical field of fingerprint identification, in particular to fingerprint identification attendance equipment based on the Internet of Things. Top shells are fixedly connected to the left side and the right side of the upper surface of an outer shell, a first air bag is movably connected into the outer shell, and a first connecting rod is movably connected to one endof the first air bag; a recording plate is movably connected to one end of the first connecting rod, a first pressing rod is fixedly connected to the top end of the first air bag and movably penetrates through the upper surface of the shell, and a second pressing rod is fixedly connected to the bottom end of the first air bag and movably penetrates through the interior of the shell; an air storage box is fixedly connected to the bottom end of the interior of the outer shell and located below the recording plate, the first air bag deforms and extrudes the first pressing rod to enable the firstpressing rod to move upwards, the first pressing rod moves upwards to extrude water in the water storage bag to be sprayed to the recording plate in a mist mode, the push plate also extrudes the water storage bag to spray water mist, and the effect of wetting dry fingers is achieved. The input of the fingerprint on the optical fingerprint identification equipment is facilitated.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification attendance device based on the Internet of Things. Background technique [0002] Fingerprint identification technology often appears in the access control and attendance functions of the one-card system. From the perspective of wide-area applications, the application direction of fingerprint identification technology includes four types. One is confidential systems, which require high security protection; The third is the citizen application for urban public affairs; the fourth is the authentication application that enters the virtual world of the Internet from real life. When employees check their attendance at work, they need to enter their fingerprints in advance and save them in the punch card machine. The identity can be identified by entering the same fingerprint again at the same time. [0003] Due to the limitations of the ...

AI Technical Summary

Problems solved by technology

[0003] Due to the limitations of the fingerprint collection principle, it is difficult for optical fingerprint collectors to collect clear fingerprint images for dry fingers, resulting in the low recognition rate of dry fingers and high rejection rate of this product. The drier the fingers, the more prominent this problem , especially in the cold climate in northern winter, many people’s fingers cannot be recognized due to dry fingers. Secondly, when registering fingerprints, the strength and range of fingers pressing on the recording board may be uneven. Interlacing forces will be generated, which will cause fingerprints to be difficult to identify on the surface of the recording board, and need to be entered again, which reduces the efficiency of punching cards and wastes employee time. Therefore, those skilled in the art provide a fingerprint recognition attendance device based on the Internet of Things to solve Problems raised in the background art above
