Embodiment:
Below in conjunction with embodiment the present invention is further described.As illustrated in figs. 1 and 2, this open system that can discern fingerprint, comprise key main body 1 and lockset 2, key body 1 is provided with the circuit part that is connected to form by IrDA interface circuit, fingerprint sensor circuit, power circuit, memory circuitry, fingerprint identification module circuit; Wherein the fingerprint identification module circuit joins with the part interface of IrDA interface circuit, fingerprint sensor circuit, power circuit, memory circuitry respectively; The power output end of power circuit and the power end of other circuit join so that working power to be provided; Lockset 2 is provided with the actuating unit that is made of processing unit module, performance element module and IrDA interface circuit; Be connected by the IrDA interface circuit between key main body 1 and the lockset 2 and carry out the signal data transmission.Be provided with the management devices 3 that can make key bring into play various functions, its circuit part mainly comprises: single chip circuit, keyboard circuit, liquid crystal display circuit and IrDA interface circuit.Wherein the relevant interface of the IrDA interface circuit that constitutes with S1～4 keyboard circuits, LCD1 liquid crystal display circuit and U6 respectively of U1 single chip circuit joins; Be connected by the IrDA interface circuit between key main body 1 and the management devices 3 and carry out the signal data transmission.
As shown in Figure 7, main concrete wiring is: 3,2 and 9 pin of interface chip U2 join with HD0, HD1 and the RST pin of fingerprint identification module circuit respectively; The HD3 pin of fingerprint identification module circuit is connected with 43 pin of the sensor chip U1 of fingerprint sensor circuit with R8, R9 by D1, D2.As shown in Figure 8, main concrete wiring is: 7,5 and 43 pins of singlechip chip U1 respectively with interface chip U6 3,2 and manage 9 pin and join, 40,41,42,43 and 44 pins of singlechip chip U1 join with 10,11,12,13 and 14 pins of LCD1 chip respectively, and 1 pin of singlechip chip U1 joins by 1 pin of R1 and triode PK1 and LCD1 chip.
Principle of work: can not discern possessor's true and false in order to overcome the existing machinery key, and the fingerprint lockset limitation of only limitting the owner to open in person, the present invention has installed fingerprint identification module on " key ", and whether the fingerprint of opening the people with identification is legal; And increase and authorize and the coerce-proof function; The fingerprint authentication function is separated from known base system, fingerprint authentication is embedded in the fingerprint key goes simultaneously.Potential safety hazard when being coupled with actuating unit in order to stop opening device (fingerprint key), and adopt the random number safety authentication protocol, carry out both sides' communication.
The course of work: as shown in Figure 3, in advance with legal user's fingerprint storage in key.When opening with it, the user presses finger on the living body finger print sensor, its fingerprint is collected and recorded by fingerprint identification module wherein at once, through calculation process, the fingerprint that is stored in advance in the key is compared, judge this living body finger print whether with key in the fingerprint of typing in advance, be the fingerprint of same finger.Reach the purpose of confirming legal user with this.Then,, carry out coded communication, impel it to finish corresponding breakdown action with actuating station by the infrared interface of fingerprint key.
As described in Fig. 4, Fig. 5 and Fig. 6, realize the functions such as management, mandate and coerce-proof of fingerprint key by management devices 3.
One, the management of fingerprint key
1) fingerprint login
Comprise the login of standby fingerprint and coerce-proof fingerprint.
2) fingerprint deletion
The user can delete the fingerprint of oneself at any time, comprises using fingerprint and anti-
Coerce fingerprint.After the user is with the deletion of coerce-proof fingerprint, at preventing of this user
Coercing function will close, and login new coerce-proof fingerprint from newly opening up to this user
Open.
Two, user management:
1) change of user's access times
When the user can legal use key, at any time can to own next
The level user carries out the change of access times.But the number of times of appointment is less than authorizing usefulness
The access times at family oneself.
2) user right change
When the user can legal use key, at any time can be to own next stage
The user carries out the change of rights of using.Specified power is less than or is equal to authorizes
User's oneself authority.
3) user's deletion
When the user can legal use key, can delete at any time own next
The level user.In deletion next stage user, system will delete link automatically
In all later users of this user.Three, authorize
User in the key can license to key new user.Whole mandate comprises two parts: authorize new user will register substantially at key earlier, login one piece of fingerprint, then the new registration user is carried out authorizing of authority.Authorized user is divided into two kinds from the angle of gained authority:
1) imitates authorized user entirely
The full authorized user of imitating can be opened all locks that this key was registered, and has
High authority.
2) part authorized user
Can only open wherein one or several locks, and key was registered other
Lock invalid.
Key can authority mandate in multistage minute, and the user of back one-level can only be less than or be equal to previous stage user's authority.In some special occasion, the user is when authorizing the next stage user, can also specify the legal access times of new user to this key, the number of times of appointment is less than the access times of authorizing user oneself, after mandate is finished, conferrer's access times will deduct new user's access times.Access times are zero user can not re-use this key except deletion action other functions.
