Fingerprint identification device
Technical field
The utility model relates to a kind of recognition device, particularly a kind of fingerprint identification device.
Background technology
Along with the development of fingerprint identification technology, fingerprint recognition system is more and more applied in daily life, such as fingerprint identification entrance guard system, fingerprint recognition notebook computer, fingerprint recognition mobile telephone terminal etc.And finger print acquisition module is also divided into optical profile type, semicoductor capacitor formula and RF-type; during for safety-security area; latter two acquisition mode level of security is higher; but require also higher to finger; dry finger, wet finger, shallow texture finger all cannot identify, existing fingerprint identification device does not have the function of fault self-checking and circuit protection yet simultaneously.
Utility model content
The purpose of this utility model is just to provide a kind of fingerprint identification device, can solve the problem completely.
To achieve these goals; the technical solution adopted in the utility model is such: fingerprint identification device of the present utility model; comprise insulation crust; insulated substrate is provided with in insulation crust; insulated substrate is respectively equipped with fingerprint collecting window, drive unit, display module and fault self-checking device; fingerprint collecting window is electrically connected with drive unit and display module respectively; drive unit is electrically connected with fault self-checking device; be provided with fingerprint erasing apparatus in fingerprint collecting window, in drive unit, be provided with circuit protection device.
As preferably, also comprise conductive film, conductive film is arranged on fingerprint collecting window, drive unit, display module and fault self-checking apparatus surface.
As preferably, adopt between described insulated substrate and insulation crust and be slidably connected.
Compared with prior art; the utility model has the advantage of: this fingerprint identification device effectively can improve the reliability of fingerprint recognition system; avoid the potential safety hazard because latent prints or fingerprint are replicated and produce, and have the function of fault self-checking and circuit protection concurrently, effectively improve utilization rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, fingerprint identification device of the present utility model, comprise insulation crust 1, insulated substrate 2 is provided with in insulation crust 1, insulated substrate 2 is respectively equipped with fingerprint collecting window 4, drive unit 5, display module 8 and fault self-checking device 9, fingerprint collecting window 4 is electrically connected with drive unit 5 and display module 8 respectively, drive unit 5 is electrically connected with fault self-checking device 9, fingerprint erasing apparatus 6 is provided with in fingerprint collecting window 4, circuit protection device 7 is provided with in drive unit 5, also comprise conductive film 3, conductive film 3 is arranged on fingerprint collecting window 4, drive unit 5, display module 8 and fault self-checking device 9 surface, adopt between described insulated substrate 2 and insulation crust 1 and be slidably connected.
This fingerprint identification device effectively can improve the reliability of fingerprint recognition system, avoids the potential safety hazard because latent prints or fingerprint are replicated and produce, and has the function of fault self-checking and circuit protection concurrently, effectively improve utilization rate.Fingerprint collecting window 4, drive unit 5, display module 8 and fault self-checking device 9 all adopt and automatically control, when touching fingerprint collecting window 4, its drive unit 5, display module 8 and fault self-checking device 9 will play self-acting automatically, thus better carry out fingerprint recognition; Drive unit 5 drives fingerprint collecting window 4, display module 8, fault self-checking device 9 and circuit protection device 7 to work respectively, mainly plays driving effect; Also comprise conductive film 3, conductive film 3 is arranged on fingerprint collecting window 4, drive unit 5, display module 8 and fault self-checking device 9 surface, and such design makes it more better drive work; Adopt between insulated substrate 2 and insulation crust 1 and be slidably connected, carry and use all very convenient.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to right.
