Description
Technical field
The present invention relates to electronic technology, and in particular to fingerprint identification method.
Background technology
Fingerprint, since it is with unchangeable property, uniqueness and convenience, almost as the code name of living things feature recognition
Word.Fingerprint refers to the convex recessed uneven streakline produced of the positive surface skin of the finger tips of people.The regular arrangement form of streakline is different
Line type.Starting point, terminal, binding site and the bifurcation of streakline, are known as the details of fingerprint.
Fingerprint recognition is widely used in mobile phone, then when people use mobile phone, fingerprint identification module often with human hand or
Other objects are contacted, so as to cause fingerprint identification module to start, such maloperation can cause unnecessary energy consumption.
The content of the invention
It is an object of the invention to provide fingerprint identification method, solves easily to exist in existing fingerprint identification method and grasps by mistake
The problem of causing unnecessary energy consumption.
To solve above-mentioned technical problem, the present invention uses following technical scheme：
Fingerprint identification method, comprises the following steps：
A, start：Pressure sensor is set, and pressure sensor is pressurized, and transmits signals to first detection module；
B, touch objects attribute is detected：First detection module starts the biological information of detection touch objects；
C, touch objects are judged：Judge whether the biological information that first detection module obtains is biology, and first detection module is obtained
Biological information judged compared with biomolecule information database, when the biological information is judged as biology, by biological information
The second detection module is transferred to, and carries out lower sequence step, when the biological information is judged as abiotic, is terminated；
D, touch objects lines is gathered：Start the second detection module to be acquired the lines information of touch objects, obtain lines information；
E, lines is identified：Lines information is judged compared with lines information database, exports judging result.
Pressure sensor, which is pressurized, just to be started, and avoids human hand from touching the startup for causing fingerprint recognition system by mistake, causing need not
The energy consumption wanted, after pressure sensor is pressurized, first detection module first checks the information of the biological information of touch objects, avoids
It is that other non-human objects are pressed caused by pressure sensor, if it is determined that it is abiotic, then terminate, if it is determined that making a living
Thing, then the second detection module the lines information of touch objects is acquired, eventually through by lines information and lines information data
Storehouse contrasts, and exports judging result.Again during this, it is therefore prevented that fingerprint recognition system caused by the touching of non-human object, pressing
The unnecessary energy consumption of system.
Preferably, in the detection touch objects attribute step, the biological information is temperature.
Preferably, in the detection touch objects attribute step, the biological information further includes electric current.Human body carries
Micro-current, further confirms that whether be biology by detecting micro-current.
Preferably, in the collection touch objects lines step, second detection module uses capacitive sensing
Module.
Preferably, in the identification lines step, when the judging result of output is to differ with lines information database
During cause, the second detection module is transmitted signals to, again repeated acquisition touch objects lines step, identification lines step.When first
The lines information of secondary collection be judged as with lines information database it is inconsistent when, then repeated acquisition, judge, it is not necessary to again again
Hand is taken away, is re-pressed, is not required to carry out the detection of touch objects attribute again, then identifies faster, also reduces energy consumption, and can repeatedly into
Row identification.
Preferably, the pressure sensor is also connected with the second detection module, will when pressure sensor is not pressurized
Signal is transferred to the second detection module, and the second detection module terminates.I.e. when human hand is taken away, then stop the second detection mould at once
The work of block, reduces energy consumption.
Compared with prior art, the present invention can at least produce a kind of following beneficial effect：The present invention can effectively avoid human hand
Touch by mistake, non-human thing pressing etc. fingerprint recognition system caused by maloperation unnecessary energy consumption；The present invention is in identification biological information
When, more accurately；The present invention is when judging that lines information is inconsistent with lines information database, it is not necessary to again again takes hand
Open, re-press, be not required to carry out the detection of touch objects attribute again, then identify faster, also reduce energy consumption, and can repeatedly be known
Not；The present invention then stops the work of the second detection module at once when human hand is taken away, and reduces energy consumption.
