The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Embodiment 1:
Shown in Fig. 1-2, a kind of novel anti-theft safety cabinet comprises the main control module of facility on safety cabinet and split type terminal;
Split type terminal contour is small and exquisite, is fit to hang on the key chain carry, or deposits as USB flash disk.
Described main control module comprises host microprocessors, host display, button, unlock drive mechanism, fingerprint capturer, circuit for generating random number, infrared transmission module and stores the mainframe memory of preset password, the default number of string of unblanking, default finger print information;
Described button, mainframe memory, unlock drive mechanism, fingerprint capturer, circuit for generating random number and infrared transmission module all are connected with host microprocessors;
Described terminal comprises terminal microprocessor, terminal display screen, battery and infrared receiving module and stores the terminal memory of a plurality of numbers of string of unblanking; Terminal display screen, terminal memory, battery all are connected with terminal microprocessor with infrared receiving module.
Described host microprocessors adopts dsp processor, and described terminal microprocessor adopts single-chip microcomputer.
The course of work is as follows:
(1) preliminary step: at the main control module end, the user sets password by button and the string number of unblanking 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, host display 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) password checking step
Host display prompting input password, the user is behind input password after the prompting, and host microprocessors is checked the password of input with the password that prestores, if confirmation enters next step, otherwise the prompt cipher authentication failed finishes the program of this time unblanking;
(3) string number transmission and checking step:
After fingerprint authentication is correct, the user press obtain the string number button, circuit for generating random number generates a real-time random number, and this random number sent to terminal by infrared transmission module, after terminal receives this random number, as index, find unblank string number, very a string a of with this random number corresponding at terminal memory with this random number; String a is presented on the terminal display screen.
At this moment, in host side, host microprocessors is corresponding with this random number string number of unblanking, very a string b in mainframe memory also;
The user by button at host side input string a, host microprocessors comparison string a and b, as identical, the string of then unblanking number is proved to be successful, namely the prompting string is number correct, and the cabinet door of startup unlock drive mechanism opening safety cabinet, finishes the process of unblanking.In 1 minute, do not pass through string number checking, then can't open the cabinet door.
