Description
Technical field
The present invention relates to biometric devices field, more particularly to a kind of personnel identity discriminating gear.
Background technology
With the development of economy and society, fingerprint machine device is widely used in library, office building, resident living area, work
The occasions such as plant area of factory, to be efficiently completed such as gate inhibition's identification, attendance record function.
The fingerprint machine for being used to implement attendance record generally has the characteristics that utilization rate is high in upper and lower class's time.Refer to improve
The recognition efficiency of line machine, in the prior art, by designing, highly efficient fingerprint compares algorithm to those skilled in the art, design is read
Installation form of the modulus block in fingerprint slot, design barn door etc. achieve the purpose that improve fingerprint machine recognition speed.How into
One step improves the recognition speed of fingerprint machine, is the major issue in fingerprint machine R＆D process.
Invention content
It is important in fingerprint machine R＆D process for the recognition speed for how further improving fingerprint machine set forth above
The problem of problem, the present invention provides a kind of personnel identity discriminating gears.The structure design of this entrance guard device causes it in winter
Still higher personnel can be kept to recognize speed.
In view of the above-mentioned problems, a kind of personnel identity discriminating gear provided by the invention solves to ask by following technical essential
Topic：A kind of personnel identity discriminating gear including fingerprint machine ontology, further includes the preparation block being set on fingerprint machine ontology, institute
It states preparation block and includes wetting pad and heating module, the heating module is embedded in wetting pad or wetting pad is pasted on heated mould
On the outer surface of block；
The heating module includes metal shroud, heating wire and insulated isolating frame, and heating wire and insulated isolating frame are respectively mounted
In the inside of metal shroud, and insulated isolating frame is as the intermediate connector between heating wire and metal shroud inner wall.
In the prior art, due to weather, when particularly it is cold, the finger sweat pores being exposed in air are received
Contracting, finger skin drying, for fingerprint machine when carrying out fingerprint recognition, fingerprint reads the reading face of block on the surface of finger and fingerprint machine
Plate surface is insufficient contact, and recognition effect is poor.For overcome described problem, people can be by blowing to finger after, treat finger watch
After aqueous vapor is agglomerated to supplement the moisture of dry skin in face, then carry out fingerprint and read to obtain better recognition effect.More than however
There is the unhygienic and so that several seconds needed for skin diastole expansion in the means for improving fingerprint recognition effect.
Water absorption pad can be used in this programme, the wetting pad, and more than heating module is used to heat wetting pad, in winter
It, can be by first pressing the wetting pad for being heated and being soaked, in finger before touching fingerprint and reading block during the finger drying of human body
After upper fingerprint diastole expansion, accurate fingerprint recognition result can be obtained；Simultaneously in the present solution, due to wetting pad by advance wetting and
Heating, finger are in direct contact with wetting pad and are in direct contact moisture, and by the way of being condensed using air blowing, this programme may be such that
Finger skin is unfolded faster, achievees the purpose that improve fingerprint recognition speed；This programme is compared to existing wetting finger of blowing simultaneously
Scheme it is more hygienic：Finger can not only be avoided to touch oral cavity；It can avoid passing through simultaneously and touch fingerprint reading block and oral cavity occurs
Germ cross-infection；Simultaneously in the working clearance of the present apparatus, wetting pad can be heated at high temperature to clean by heating module
Wetting pad.
Meanwhile the structure design of heating module causes it can heat production under electric energy in this programme so that this programme has
The characteristics of easy for installation, simple in structure, light-weight；Meanwhile the structure design of heating module can utilize the metal that material is metal
