The utility model content
Technical problem to be solved in the utility model provides a kind of novel intelligent safety cabinet, and this novel intelligent safety cabinet adopts the double verification pattern, and is safe.
The technical solution of utility model is as follows:
A kind of novel intelligent safety cabinet is provided with microprocessor, display screen, button, storer, unlock drive mechanism, fingerprint capturer, random cipher generative circuit and wireless transmitter module in the cabinet of safety cabinet;
Described display screen, button, storer, unlock drive mechanism, fingerprint capturer and random cipher generative circuit all are connected with microprocessor; The output terminal of random cipher generative circuit links to each other with wireless transmitter module.
Described microprocessor is arm processor.
Beneficial effect:
Novel intelligent safety cabinet of the present utility model, the double verification pattern that adopts the fingerprint authentication pattern and combine with the string Validation Mode of mobile phone based on random code, security is high, be difficult for cracking, and whole installation cost is low, is easy to promotion and implementation.
Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Embodiment 1:
As shown in Figure 1, a kind of novel intelligent safety cabinet is provided with microprocessor, display screen, button, storer, unlock drive mechanism, fingerprint capturer, random cipher generative circuit and wireless transmitter module in the cabinet of safety cabinet;
Described display screen, button, storer, unlock drive mechanism, fingerprint capturer and random cipher generative circuit all are connected with microprocessor; The output terminal of random cipher generative circuit links to each other with wireless transmitter module.
Described microprocessor is arm processor.
Microprocessor is main control unit, and display screen is used for display reminding information, and button is used for arranging password, and starts wireless transmitter module by button and send and be used for the string of unblanking number, and storer is used for storage password, related cell-phone number and finger print information; Unlock drive mechanism is used for driving the cabinet door unlatching of safety cabinet, fingerprint capturer is used for collection user's password to be checked for fingerprint, the random cipher generative circuit is for generation of random number, and this random number and the original password of setting multiplied each other obtains a string number, and this string number is gone here and there for unblanking number.Wireless transmitter module is used for the mobile phone related with this safety cabinet issued in the number of string.
The course of work is as follows:
(1) preliminary step: the user sets password and the phone number related with safety cabinet by button in advance, and pre-stores finger print information;
(2) fingerprint checking step:
When the user will unblank, press the unlock key on the lower cabinet body, display screen prompting input fingerprint is behind fingerprint capturer collection fingerprint, check with the fingerprint that prestores, if confirmation enters next step, otherwise unlock instruction is next time waited in the failure of prompting fingerprint authentication;
(3) string number transmission and checking step:
After fingerprint authentication is correct, the user press obtain the string number button, the random cipher generative circuit generates a real-time random number, and this random number and the original password of setting multiplied each other obtain a string number, this string number is for unblanking string number, and will the number of string issues the mobile phone (this string number the term of validity be 1 minute) of association; This string number also is stored in the insurance predetermined memory.
After mobile phone was received this string number, the user should go here and there number by the button input, and microprocessor core is to correctly, and namely the prompting string is number correct, and started the cabinet door of unlock drive mechanism opening safety cabinet, finished the process of unblanking.In 1 minute, do not pass through string number checking, then can't open the cabinet door.
