As shown in figure 1, first thread includes：
Step 101：Gather biometric image；The harvester collection biometric image of the biological gate inhibition of first thread control.
Step 102：Sent to the 3rd thread and open display interface signal, the 3rd thread is received after display interface signal,
Display interface can be opened, display is ready for.
Step 101 and 102 is without strict sequencing relation.
Step 103：Sent to the 3rd thread and update display interface signal, to be shown, wherein updating display interface letter
Biometric image is included in number；3rd thread is received after renewal display interface signal, display interface can be refreshed, display is adopted
The biometric image collected.
Step 104：Extract the biological characteristic of biometric image；First thread using specific algorithm to biometric image at
Reason, extracts biological characteristic (characteristic value, characteristic vector or eigenmatrix etc.), for example, if recognition of face, can use volume
Product neutral net etc. extracts face characteristic, if fruit is iris recognition, the methods such as Gabor filtering can be used to extract iris special
Levy.
Step 105：Biological characteristic is sent to the second thread；The biological characteristic extracted is sent to the second line by first thread
Journey, so that the second thread is authenticated.
Step 106：Judge whether to meet the condition for closing interface, display interface is closed if so, then being sent to the 3rd thread
Signal, to close display interface；3rd thread is received after closing display interface signal, closes display interface；Close interface
Condition has a variety of situations, general, if certification is finished, (including certification a variety of feelings such as leaves by, certification time-out, user
Condition), for example, can think after first thread receives the certification pass signal of the second thread transmission (after authentication authorization and accounting success)
The condition for closing interface is met, a kind of this situation is only enumerated here, is specifically listed again when other situations are mentioned later.
As shown in Fig. 2 the second thread includes：
Step 201：The biological characteristic sent using first thread is authenticated, if certification passes through, to first thread and
3rd thread sends certification pass signal；First thread is received after certification pass signal, that is, thinks to meet the bar for closing interface
Part, the 3rd thread is received after certification pass signal, can be pointed out (sound is exported and/or image is shown), and now give birth to
Thing gate inhibition can open the door.
First thread (including step 101 to step 106) and the second thread (step 201) are parallel each other, are not had

Also, inventor also found, even if the recognition methods of biological gate inhibition is simply divided into three threads, each thread
Corresponding order can be performed according to the judgement of itself, if the signal circulation between the arrangement of the step of thread and each thread is arranged not
Rationally, it will result in the situation of command collision.Such as the 3rd thread needs to be controlled according to the signal of first thread and the second thread
The operations such as display interface opening processed, closing and display, conflict if the signal of first thread and the second thread is present, the 3rd thread
Display also occurs chaotic (including switching chaotic, display confusion etc.).
If opening display interface signal for example, being sent from first thread to the 3rd thread, display interface is opened, and by second
Thread sends to the 3rd thread and closes display interface signal, and closing display interface, (this is very common, because certification success is latter
As can all close display interface), if first thread does not know that the second thread have sent closing display interface signal, then the
One thread can send to the 3rd thread and open display interface signal again, open display interface so that after the authentication has been successful can not
Normal switching-off display interface, causes switch chaotic.
The present embodiment only controls the 3rd thread to open (step 102) and closes (step 106) by the signal of first thread
Display interface, is not in the switch confusion of display interface；In addition, the renewal that display interface is sent according to first thread shows boundary
Face signal shows biometric image, then shows the authentication result (certification pass signal) that the second thread is sent, i.e. first display in real time
Biometric image, then after authentication result is obtained, refreshes display screen, shows authentication result, be not in the display of display interface
It is chaotic.Therefore, the present embodiment can avoid the command collision problem between multiple threads.

After identification process, first thread is not created immediately, only when judging to meet acquisition condition, can just be created and be run First Line
Journey).
It can judge whether to meet the condition of collection by various methods, the present embodiment is by user with biological gate inhibition's
Distance judges, if for example, the distance of user and biological gate inhibition are less than certain value, preferably 50cm, then it is assumed that meet collection
Condition.Now, on the judgement for meeting the condition for closing interface in step 106, if the distance of user and biological gate inhibition are big
In certain value, preferably 50cm, then it is assumed that user has been moved off, that is, meet the condition for closing interface.If also, keeper logs in
To biological gate inhibition, and when pressing the collection button of correlation, it is also assumed that meeting the condition of collection.
Also, after judging to meet the condition of collection, first thread can be sent out signal and wake up or create the second thread
(it can be described behind detailed process) with the 3rd thread.
Now, in first thread, in the step of judging whether to meet the condition for closing interface (step 106), if not meeting,
Then go to the condition (step 100) for judging whether to meet collection；If once certification does not pass through, first thread repeats each
Step, resurveys biometric image, carries out certification again, until by or time-out (overtime specific judgment step is follow-up
It can introduce).
