Detailed description of the invention
It in order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below will be to institute in embodiment Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some implementations of the invention Example, for those of ordinary skill in the art, without creative efforts, can also obtain according to these attached drawings Obtain other attached drawings.
Fig. 1 is the schematic diagram that fingerprint according to an embodiment of the present invention adds vocal-print puzzle lock;
Fig. 2 is the process for using figure that fingerprint according to an embodiment of the present invention adds vocal-print puzzle lock.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art's every other embodiment obtained belong to what the present invention protected Range.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.Meanwhile " first " in the application, " Two " merely to distinguish each module, is not the particular number for limiting each module.
Referring to FIG. 1, the fingerprint adds vocal-print puzzle lock to include shell, operation panel, operation panel packet are provided on shell The user for being built in by fingerprint identification module and being constituted in the key of keyboard is included when carrying out key while acquiring the of user's input It the outdoor finger-print cipher input module of one encrypted message and the first finger print information and is built in the inside of shell and use can be received The vocal print input module of first voiceprint of family input, operation panel are also connect with control panel.
By means of above-mentioned technical proposal of the invention, by the way that fingerprint identification module is built in the key of keyboard, thus User only has optional network specific digit to be pressed just effectively by particular fingerprint when inputting password, even if all numbers in input password are all just Really, if do not pressed by corresponding particular fingerprint, finally and input password fails, and after finger-print cipher passes through, can prompt to use Family reads aloud string number and carries out Application on Voiceprint Recognition, could only unlock eventually by Application on Voiceprint Recognition.It is effectively utilized everyone The uniqueness and uniqueness of fingerprint, and fingerprint and vocal print are combined, so as to greatly enhance cipher safety, this Outside, which does not need user yet and remembers very complicated password, facilitates user's memory, practical.
In one embodiment, as shown in Figure 1, operation panel further comprises: in-house operation panel, in-house operation panel It is connect with control panel, the room for carrying out password setting, fingerprint setting and vocal print setting for user is provided on in-house operation panel Interior fingerprint vocal print Password Input module;Field operation panel, field operation panel are also connect with control panel, field operation panel On be provided with for user carry out Password Input and fingerprint input outdoor finger-print cipher input module and be built in field operation face Plate is interior and can receive the vocal print input module of the vocal print of input.
In this embodiment, for the ease of enhancing the cipher safety that the fingerprint adds vocal-print puzzle lock, by the operation panel It is divided into in-house operation panel and field operation panel, the addition of password, fingerprint and vocal print is carried out by in-house operation panel, is repaired The settings operation such as change, delete, the input of fingerprint and vocal print and password also being carried out by field operation panel, to realize interior Fingerprint and vocal print and password are set, solves user and is peeped numerical ciphers in outdoor setting cryptographic processes or collect residual Security risk caused by fingerprint in related key etc., the case where adding vocal-print puzzle lock to be opened so as to avoid the fingerprint, And then substantially increase safety.
In addition, in order to further enhance safety, sliding slot is additionally provided in the symmetrical two sides of field operation panel, and Cleaning roller is also connected with by movable pulley in the sliding slot, to can also carry out by cleaning roller after user inputs password Cleaning, to eliminate the fingerprint on key, to prevent the fingerprint residues of user on key.
In one embodiment, as shown in Figure 1, control panel further comprises: memory module is stored in memory module The good setting information of user setting, wherein setting information includes the second encrypted message, the second finger print information and the second vocal print letter Breath;First control module, the first control module are connect with indoor control panel, outdoor control panel and memory module respectively, the One control module is used for the input information inputted according to the setting information stored in memory module and user, generates unlock letter Breath, wherein input information includes first password information, the first finger print information and the first voiceprint.
In this embodiment, user passes through the correspondence order that password and fingerprint is arranged in indoor fingerprint vocal print Password Input module Relationship and vocal print are storable in memory module, and after the first control module gets the input password of user, can be incited somebody to action Correspondence orbution in the input password and memory module of user is compared, and e.g., " 3 " key-value pair answers middle finger fingerprint, then " 5 " key-value pair answers index fingerprint etc., it is of course possible to understand, the fingerprint between different key assignments may be the same or different, and the present invention is to this Without limitation.It should be noted that can also store other in addition to the password and fingerprint of the above-mentioned setting of storage in the memory module Information.
In addition, the fingerprint adds the use process of vocal-print puzzle lock in order to facilitate understanding, below by the process for using in Fig. 2 Figure is described.
As shown in Fig. 2, needing to be arranged 1 key of function on in-house operation panel before the fingerprint adds vocal-print puzzle lock use For typing fingerprint pattern, any fingerprint, the corresponding finger of different digital can be pressed on any 1-9 digital keys by pressing rear user Line can be same or different, and, 2 key of function on in-house operation panel is also set up as setting cipher mode, is used after pressing Oneself desired password can be set in family, in addition, also setting up 3 key of function on in-house operation panel as setting vocal print mode, presses The voiceprint of oneself can be set in user after lower.In addition, when actually use the fingerprint add vocal-print puzzle lock to make when, input it is close If containing number corresponding to typing fingerprint in code, which must be pressed just effectively by corresponding fingerprint, if input is close Include the number of no typing fingerprint in code, then default any fingerprint and press effectively, the password of end user's input must own Number and fingerprint all match, and password correctly enters Application on Voiceprint Recognition afterwards, and only Application on Voiceprint Recognition can just open door lock after passing through, otherwise Password Input failure.
In one embodiment, as shown in Figure 1, operation panel further include: first be arranged on operation panel indoors is aobvious Show module;The second display module and lighting module on field operation panel are set, and the setting of the second display module is in illumination mould In the illumination region of block;First display module, the second display module and lighting module are connect with the first control module.
