State shows pseudo random number；When pressure sensor in each position is pressed into default value, using thumb press it is described confirm by
Key, is pressed after confirming button, and control board extracts the finger print information that the finger print acquisition module of correspondence position is got, and forms four
A fingerprint sequence according to different pressures value while sequential arrangement, control board independently set fingerprint sequence with user
Fixed fingerprint sequence information compares, if fingerprint sequence information is consistent, judges that Password Input is correct, control board control electric mortiser
Lock performs unlocking step, if fingerprint sequence information is inconsistent, judges Password Input mistake, and user is prompted again by display screen
Input password.
The default value of the pressure is fixed numbers, when pressing the pressure sensor, when real-time pressure value with
Difference between the fixed numbers of setting is less than 0.2 Newtonian time, it is believed that real-time pressure value is equal to default value；The display
The precision of shown real-time pressure numerical value is 0.1 newton on screen.
The real-time pressure value precision of the display screen display be 0.1 newton, and is multiplied by 10 and is scaled integer and show, such as pressure
Force value is 0.2 Newtonian time, shows screen display 2（Value shown on display screen is hereafter denoted as pressing force）.
In order to be more clearly understood that the key of fingerprint password input device, citing below further illustrates：Such as forefinger, in
Finger, nameless and little finger of toe correspond to 1,2,3 and 4 respectively, if setting code is 2143, set pressing force as 8765（Pressure may be selected
Numerical value is 1-8）, then middle finger is pressed successively, makes to press confirmation button when secondary series is shown in the range of 6 to 10 on display screen, then
Forefinger is pressed, makes to press confirmation button when first row is shown in the range of 5 to 9 on display screen, then presses little finger of toe, make on display screen
Confirmation button is pressed when in the range of the 4th row display 4 to 8, finally presses the third finger, the 3rd row on display screen is shown 3 to 7 models
Confirmation button is pressed when enclosing interior.
Certainly, password can also be set to common 6 bit digital, for example setting code is 232421, set pressing force as
876567, then middle finger is pressed successively（Secondary series pressure shows 6 to 10）, it is nameless（3rd row pressure shows 5 to 9）, middle finger（The
Two row pressure show 4 to 8）, little finger of toe（4th row pressure shows 3 to 7）, middle finger（Secondary series pressure shows 4 to 8）, forefinger（First
Row pressure shows 5 to 9）.
When the pressure sensor of correspondence position be under pressure value be zero when, the respective column Dynamic Announce pseudorandom on display screen
Number.The pseudo random number can carry out calculating acquisition, such as a position according to the real-time pressing force of the pressure sensor being under pressure
The pressure sensor the put value that is under pressure is N（N is 1-8）When, the pressure of other three positions is shown as（N+2）、（N+3）With
（N-1）.
By above-mentioned technological means, since four column of figure are closer on display screen, only user oneself knows see
The numeral of which row, even if other people look at display screen, observation user is operated, and can not also know the password that user specifically inputs.
The installing port passed through for the finger print acquisition module is formed on the convex groove body side wall；On the outside of the upper shell
Upper end is integrally formed with the connection flange 313 being fixedly linked with right door body inner wall.
When Password Input errors number is more than 3 times in setting time, control board is by wireless network to server
Send alarm signal.
When electric mortise lock is in the unlocked state, pressing the finger print acquisition module of optional position makes the pressure sensing of correspondence position
Device detects pressure, then the locking of control board control electric mortise lock.
Embodiment 2
The present embodiment makes following improvement on the basis of embodiment 1：Entrance top is stretched in the door body positioned at finger to be provided with
Cipher inputting keyboard, the cipher inputting keyboard are electrically connected with control board, when opening cabinet door, if user is used to input fingerprint
The Toe Transplantation for Segmental Finger of password is injured and when can not normally input complete finger print password, user is by index finger, middle finger, ring finger and little finger
Any one above finger by finger print acquisition module at an arbitrary position, control board extracts at least one fingerprint collecting
The finger print information that module is got, and be compared with the finger print information that user independently sets, after matching user identity, control electricity
Road plate sends dynamic verification code to the mobile terminal of corresponding user identity binding, and user is on the basis of the numerical value of dynamic verification code
Set of number password, user's input numerical ciphers on the numeric keypad 34 of cabinet door outer wall are obtained plus a dynamic setting numeral
Afterwards, control board control electric mortise lock a performs unlocking step.
Dynamic setting numeral is user by the correspondence finger on finger-print cipher input module, forefinger, middle finger, unknown
Refer to and little finger of toe corresponds to 1,2,3 and 4 respectively.
For example only forefinger is pressed when on a finger print acquisition module, the pressure sensor of correspondence position detects pressure,
It is 1 that then dynamic, which sets numeral,；As middle finger and little finger of toe are pressed from left number second, the 4th finger print acquisition module, then correspondence position
Pressure sensor detect pressure, then dynamic set numeral be 24；As forefinger, middle finger, nameless three fingers press first,
Second and the 3rd finger print acquisition module on, three pressure sensors detect pressure, then dynamic set numeral be 123.
The digit that dynamic sets numeral is previously set by user；For example dynamic password is 756452, dynamic, which sets numeral, is
134, then the second group of password inputted is 756586.
Means in this way, even if other people have stolen dynamic verification code on the mobile phone of user and certain using illegal means
The fingerprint of a little fingers, due to being difficult to the digit for knowing that dynamic sets numeral, it is only necessary to limit Password Input at the appointed time
Number, other people are just difficult to the password for cracking safety cabinet.
