Embodiment 1
The embodiment of the invention 1 provides a kind of method that detects data card pressure and prompting user, sees also Fig. 1, and the method specifically comprises:
In this step, data card can detect its suffered ambient pressure according to various pick-up units.For example, detecting the suffered pressure of data card can detect by the pressure sensitive device.Pressure transducer commonly used can be set in data card detect the data card pressure, such as resistance strain gage pressure transducer, semiconductor gauge pressure transducer, piezoresistive pressure sensor, inductance pressure transducer, capacitance pressure transducer,, resonance type pressure sensor and capacitance acceleration transducer etc.Certainly, include but not limited to that in embodiments of the present invention the adopts pressure sensor device detects the pressure that is applied on the data card.

Embodiment 2
The embodiment of the invention 2 provides a kind of method that detects data card pressure and prompting user, sees also Fig. 2, and the method specifically comprises:
In this step, data card can detect its suffered ambient pressure according to various pick-up units.For example, detecting the suffered pressure of data card can detect by the pressure sensitive device.Pressure transducer commonly used can be set in data card detect the data card pressure, such as resistance strain gage pressure transducer, semiconductor gauge pressure transducer, piezoresistive pressure sensor, inductance pressure transducer, capacitance pressure transducer,, resonance type pressure sensor and capacitance acceleration transducer etc.Certainly, include but not limited to that in embodiments of the present invention the adopts pressure sensor device detects the pressure value that is applied on the data card.
The data that detect by the pressure sensitive device are the numerical value of some analog electrical signals, and this electric signal numerical value becomes certain corresponding relation with pressure.After electric signal numerical value is changed by digiverter, can convert the numerical value of digital signal form to, read this numerical value for data card.
Further, this pressure value can be signal numerical value, and this signal numerical value is according to the detected pressure value of pressure-detecting device.
Further, this pressure value also can be color value, and this color value is the detected pressure value of fingerprint sensor.Particularly, see also Fig. 3, this color value can parse by the following method:
Information in fingerprint is that terminal detects the image information that produces behind user's the fingerprint, and this information in fingerprint can be color image information or monochrome image information.
In embodiments of the present invention, most fingerprint sensors can gather information in fingerprint by three kinds of main sensing technologies such as optical scanning, semiconductor temperature-sensitive, semicoductor capacitor.
The situation that gathers information in fingerprint in this step is described as an example of the semiconductor fingerprint sensor example.The semiconductor fingerprint sensor comprises semi-conductor electricity capacity sensor, semiconductor pressure-sensitive sensor, conductor temperature induction pick-up etc.Take the semiconductor fingerprint sensor as example, the top layer of semiconductor pressure-sensitive sensor is whippy pressure sensitivity dielectric material, user's fingerprint is with after this pressure-sensitive sensor contacts, on this flexible pressure sensitivity dielectric material, according to the concavo-convex corresponding electric signal that is converted into of fingerprint, and generation has the gray level fingerprint image.Particularly, semiconductor pressure-sensitive sensor is that deformation by the pressure-sensitive dielectric material of perception semiconductor forms picture signal.Adopt the fingerprint sensor surface of semiconductor pressure sensitivity technology, be covered with a series of small pressure-sensitive media units.The unit that these are tiny, the variation sensing of pressure is very responsive to external world.When finger is placed into fingerprint collecting when surface, because the ridge of fingerprint is protruding, the valley is recessed, and bossing will be to pressure-sensitive unit mineralization pressure, and makes the generation deformation of pressure-sensitive unit; Because varying in size of the pressure of pressure-sensitive unit that the user acts on is like this so that deformation in various degree can occur in pressure-sensitive unit.Because after the deformation of pressure-sensitive unit, its resistance value can change, thereby causes change in voltage.Recessed valley does not produce pressure in the unit of correspondence, so its corresponding magnitude of voltage can not become changing.Just can form the numerical information of ridge and valley on the fingerprint pattern by different magnitudes of voltage, i.e. information in fingerprint.
For the semi-conductor electricity capacity sensor, the curent change detection that produces by survey sensor and finger contact/noncontact has or not fingerprint, and realizes the information in fingerprint of high reliability according to texture informations such as fingerprint ridge, valleys.Particularly, at integrated approximately 100000 capacitance type sensors (outer layer insulation) of semiconductor alloy array, the sensor array every bit is a metal electrode, is equivalent to capacitor anode; Finger is placed on when top, and skin forms another utmost point of electric capacity, and sensitive face forms two interpolar dielectric layers.Capacitance is with ridge
(near) and valley (far away) are with respect to the distance of sensor array and change.Because the fingerprint lines depth
Difference, each capacitance of silicon face capacitor array also has different, and this capacitance is converted into the 8bit gray level image,
Measure and record each point capacitance, can obtain to have the information in fingerprint of gray-scale value.Certainly, at this
Include but not limited in the inventive embodiments that above-mentioned technology gathers information in fingerprint.
This color value can be the colouring intensity value, also can be gray-scale value.
If in the information in fingerprint that receives, fingerprint image is colored, has so the colouring intensity value of fingerprint image in this information in fingerprint.In the prior art, the most frequently used color standard is RGB (Red Green Blue) color mode, is to obtain color miscellaneous by variation and their stacks each other to red (R), green (G), blue (B) three Color Channels.Rgb color pattern using RGB model is that the RGB component of each pixel in the image distributes the intensity level in 0～255 scope.For example: pure red R value is that 255, G value is that 0, B value is 0; R, G, the B of white are 255; The R of black, G, B are 0 etc., also can represent above-mentioned color with three-number set, and for example pure red is that (255,0,0), white are (255,255,255), and black is (0,0,0) etc.
If in the information in fingerprint that receives, fingerprint image is black and white, comprises so the color gray-scale value of image in this information in fingerprint.In the prior art, having represented black with numerical value 0-255 is color to white a series of black and white.For example 0 is black, and 255 is white, and the numerical value such as 45,84,145 have represented the grey in various degree between black and white.
In above-mentioned two kinds of definitions of color methods, also can realize by algorithm of the prior art the conversion of colouring intensity value and color gray-scale value.Be understandable that, in embodiments of the present invention, include but not limited to that aforesaid way determines color value.
Whether the pressure value that step 203, judgement detect is more than or equal to default threshold value.If this pressure value is more than or equal to threshold value, then execution in step 205; Otherwise, execution in step 204.
The embodiment of the invention is by detecting the suffered pressure value of data card; the threshold value of relatively presetting and the size of pressure value; technical scheme when pressure value prompting user during more than or equal to this predetermined threshold value; so that the user can the present residing abnomal condition of perception data card; thereby make data card can be because pressure be excessive injury, improved the protection to data card.In addition, when brush finger line dynamics is excessive, the user is pointed out, also greatly improved user's experience, avoided the user to operate blindly and the damage of the data card that causes.
