A kind of automobile navigation instrument with finger-print cipher functionTechnical field
The present invention relates to a kind of automobile navigation instrument, especially a kind of automobile navigation instrument with finger-print cipher function.
Background technology
Vehicle GPS navigator progressively becomes automobile essential element, the general tool of GPS comprises display, has all multicomponent devices such as processor, acceleration transducer of larger computing power, for navigation or amusement, but existing automobile navigation instrument is all the implementation pattern that simply presses switch to open, there is no external use restriction and protection.
Summary of the invention
In view of this, the object of this invention is to provide a kind of automobile navigation instrument with finger-print cipher function controlling automobile navigation instrument unlatching by finger-print cipher recognition method.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of automobile navigation instrument with finger-print cipher function, comprise GPS navigation system, central processing unit, display unit and power module, described display unit is connected with described central processing unit respectively, described power module is used for for other each module for power supply, described GPS navigation system comprises acceleration transducer, it is characterized in that, this navigating instrument also comprises the fingerprint identification module be connected with described central processing unit, described fingerprint identification module comprises the fingerprint capturer be connected with described central processing unit, and be connected fingerprint storage module with described central processing unit, and the fingerprint comparison module to be connected with described central processing unit and sender unit, electronic switch is provided with between described sender unit and described GPS navigation system, described electronic switch is connected with described sender unit wireless signal, be electrically connected with the power source active module of described GPS navigation system.
Preferably, above-mentioned a kind of automobile navigation instrument with finger-print cipher function, wherein said electronic switch has light signal to be connected with described sender unit wireless signal connected mode, infrared signal connects, Bluetooth signal connects, radiofrequency signal connects.
Preferably, above-mentioned a kind of automobile navigation instrument with finger-print cipher function, wherein said fingerprint capturer is touch-screen, and it is arranged at the exterior rim Angle Position place on the panel of described automobile navigation instrument.
Preferably, above-mentioned a kind of automobile navigation instrument with finger-print cipher function, the clear aperature of wherein said touch-screen: 80% ~ 99%, the depth of parallelism≤3.5.
Preferably, above-mentioned a kind of automobile navigation instrument with finger-print cipher function, wherein said fingerprint identification module also comprises the fault self-checking module that is connected with described central processing unit and fingerprint wipes module.
Compared with prior art, the technology of the present invention effect is mainly reflected in: also set up connection fingerprint identification module in the present invention, when the fingerprint prestored in the fingerprint and fingerprint storage module of fingerprint capturer collection is compared by fingerprint comparison module, if comparison success, signal generator controls the energising of electronic switch closes power source active module by wireless signal, GPS navigation system starts to start, if coupling one end time is success not, electronic switch is unanimously in off-state, and GPS navigation system cannot open use.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail, is easier to make technical solution of the present invention understand and grasp.
As depicted in figs. 1 and 2, a kind of automobile navigation instrument with finger-print cipher function, comprise GPS navigation system, central processing unit, display unit and power module, described display unit is connected with described central processing unit respectively, described power module is used for for other each module for power supply, described GPS navigation system comprises acceleration transducer, wherein this navigating instrument also comprises the fingerprint identification module be connected with described central processing unit, described fingerprint identification module comprises the fingerprint capturer be connected with described central processing unit, and be connected fingerprint storage module with described central processing unit, and the fingerprint comparison module to be connected with described central processing unit and sender unit, electronic switch is provided with between described sender unit and described GPS navigation system, described electronic switch is connected with described sender unit wireless signal, be electrically connected with the power source active module of described GPS navigation system.
Wherein said electronic switch has light signal to be connected with described sender unit wireless signal connected mode, infrared signal connects, Bluetooth signal connects, radiofrequency signal connects.
Wherein said fingerprint capturer is touch-screen 2, and it is arranged at the exterior rim Angle Position place on the panel 1 of described automobile navigation instrument, the clear aperature of touch-screen 2: 80% ~ 99%, the depth of parallelism≤3.5.
In addition, fingerprint identification module also comprises the fault self-checking module that is connected with described central processing unit and fingerprint wipes module.
When the fingerprint prestored in the fingerprint of fingerprint capturer collection and fingerprint storage module is compared by fingerprint comparison module when this technical scheme is implemented, if comparison success, signal generator controls the energising of electronic switch closes power source active module by wireless signal, GPS navigation system starts to start, if coupling one end time is success not, electronic switch is unanimously in off-state, and GPS navigation system cannot open use.
Certainly, be more than representative instance of the present invention, in addition, the present invention can also have other multiple embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the scope of protection of present invention.
