The utility model relates to a kind of finger-print recognising instrument, the especially a kind of finger-print recognising instrument that can realize corium living body finger print quick identification.
At present because fingerprint identification technology is used in safety guard, gate inhibition's control and information management requirement easily more and more.Various finger-print recognising instruments have appearred, these identifiers or independently use or be combined on various occasions, the equipment and use.But the pattern recognition limitation of existing fingerprint is bigger, and touch-screen generally is an optical profile type or capacitive, and photo-electric is by fingerprint surface optical imagery, and shortcoming is can not discern for dried, moist finger; Condenser type is by the capacitive sensing imaging of fingerprint surface, and shortcoming is for dried, moist finger identification very difficult; And all can not distinguish live body.Substantially can not stop the obscuring of various duplicate of fingerprint.The structure of removing static is also complicated.Also have data transmission that lead need be set in addition, not only influence environment for use, and operation such as terminal block is also inconvenient.Have, identifier touch-screen window embeds to be provided with just offers open window on mouse body, do not set up parts around the window again.When operating personnel use, to touch-screen to press sense relatively poor, and place the location sense behind the finger, therefore usually be that not know how many fingers placed more suitable, the collection that influence is visual, and then influence the whole structure of fingerprint recognition.
The purpose of this utility model is to provide a kind of finger-print recognising instrument at the deficiency of prior art, and its recognition speed is fast, and is highly sensitive, can realize the identification of the three-dimensional live body corium of fingerprint.
Another purpose of the present utility model is to provide a kind of finger-print recognising instrument at the deficiency of prior art, and its locations of structures setting meets human efficiency's technical indicator, and conveniently finger is put into the location, thereby improves the efficient of identification.
A purpose more of the present utility model is to provide a kind of finger-print recognising instrument at the deficiency of prior art, and it can transmit finger print information by Wireless transmission mode.
The purpose of this utility model is achieved in that
A kind of finger-print recognising instrument, it comprises touch-screen and inner control circuit on the finger-print recognising instrument body, and its touch-screen is the electric field induction formula, and the surface of touch-screen is a silica gel thin film, be the micro sensing electrode of discrete setting more than below the film, the output of electrode connects the sensing process chip.
The edge of described finger-print recognising instrument touch-screen is provided with the electrostatic prevention induction band, and this electrostatic prevention induction band and touch-screen are electrically connected and an end ground connection.
Described electrostatic induction band can be set to around the edge of touch-screen one circle.
Described data processing circuit input end is connected to start triggering circuit.
Described start triggering circuit is the diode that is provided with under the touch screen electrode.
Described diode is one or more.
Described data processing circuit also comprises the electrostatic prevention treatment circuit, the output terminal of its control termination sensing treatment circuit.
The data output circuit of described data processing circuit and the interface of computer are USB interface.
The data output circuit of described data processing circuit is a wireless type, and its antenna is built-in.
Described touch screen electrode has temperature sensor, and the output of temperature sensor connects the input end of data processing circuit.
Described temperature sensor can be one or more.
Described temperature sensor can be thermistor.
The window periphery that described touch-screen embeds can be established positioning body.
Described positioning body is to have the positioning body that elasticity is pressed sense of touch.
The opening shape of described positioning body can meet the shape of human finger.
According to the technique scheme analysis as can be known, the utility model can really be realized the finger print data collection of three-dimensional live body corium, gather, recognition speed is fast, and be provided with rational in infrastructure, easy to use, meet human efficiency subject's requirement fully, finger is placed with and significantly presses sense, location sense, has further realized fingerprint recognition process accurately and rapidly.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a touch screen plane structural representation of the present utility model;
Fig. 3 is a three-dimensional cross-sectional view of the present utility model,
Fig. 4 is one of circuit theory diagrams of the present utility model;
Fig. 5 is two of circuit theory diagrams of the present utility model;
Fig. 6 is three of circuit theory diagrams of the present utility model.
Referring to Fig. 1-5, the utility model is a kind of finger-print recognising instrument.On body 1, offer window, window is embedded in the touch-screen 2 that is provided with finger-print recognising instrument, the data processing circuit of finger-print recognising instrument is arranged in the body, touch-screen 2 is an electric field induction, the surface of touch-screen 2 is a silica gel thin film, is the dot matrix that the miniature electric field induction sensing electrode 24 of discrete setting more than 100,000 is formed below the film.The output of lattice electrode 24 connects the sensing process chip.Data processing circuit U1 input end is connected to the start triggering circuit of being made up of a plurality of diodes, can be arranged as a row.Become a static and trigger the line of induction 22.Therefore when touching touch-screen 2 in case there is finger 4 to press, start triggering circuit is with the identifier switch closure, and whole device starts.The interface of the data output circuit of data processing circuit U1 by conversions such as U5 and computer becomes and is USB interface, is convenient to the quick transmission of data.In addition, data output circuit also can be wireless type, utilizes technology such as infrared, radio frequency to realize, and convenient the use, and the radio frequency induction antenna is built-in.Antenna can be arranged on the circuit board body.Concrete ins and outs such as infrared, radio frequency can with existing other field use consistent.
