Description of drawings

In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the circuit block diagram of a kind of electronic lock of the present invention.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.

As shown in Figure 1, electronic lock of the present invention, comprise: first controller 101, second controller 102, GSM(global system for mobile communications, global system for mobile communications) module 103, keyboard 104, fingerprint instrument 105 and electronic lock cylinder 106.

101 receptions of first controller and checking if the verification passes, then generate a random cipher and send to gsm module 103 from phone number and the short message content of gsm module 103.Gsm module 103 is couple to first controller 101, receives the note that mobile phone sends by the GSM network, and phone number and short message content are sent to first controller 101, and the random cipher that first controller 101 is generated sends to mobile phone by the GSM network.Keyboard 104 is couple to the input end of first controller 101, the user is by keyboard 104 input random ciphers, first controller 101 compares the random cipher of input and the random cipher of generation, if the random cipher of input is identical with the random cipher that first controller 101 generates, then first controller 101 is to electronic lock cylinder 106 outputs first unlocking signal, and control electronic lock cylinder 106 carries out unlock operation; If the random cipher of input is different with the random cipher that controller 101 generates, then electronic lock cylinder 106 keeps blocking.In the fingerprint instrument 105 typing in advance user's fingerprint, when the user carries out normal fingerprint typing unlock operation, fingerprint instrument 105 judges that fingerprint is whether correct and export fingerprint and judge signal, second controller 102 is exported second unlocking signal to electronic lock cylinder 106 according to fingerprint judgement signal, and control electronic lock cylinder 106 is unblanked or kept blocking.

For example, when the user stays out, relatives and friends are in a hurry in the time of need entering the room, the user sends " password " two words for electronic lock of the present invention by own mobile phone, gsm module 103 receives note and phone number and short message content is sent to first controller 101 and verifies, if the verification passes, first controller 101 generates a random cipher, send to user mobile phone by gsm module 103, the user is as long as tell relatives and friends with random cipher, by keyboard 104 input random ciphers, if the random cipher of input is identical with the random cipher that first controller 101 generates, can open door.When having guaranteed the fingerprint electronic lock security, also provide remote control function like this, made the mode of operation variation of fingerprint electronic lock, and safer.

As shown in Figure 1, electronic lock of the present invention also comprises: first relay 107 and second relay 108, be used for the control level of

first controller

101 and 102 outputs of second controller is converted to the level that electronic lock cylinder 106 can be used, one end of first relay 107 is couple to first controller 101, the other end is couple to electronic lock cylinder 106, one end of second relay 108 is couple to second controller 102, and the other end is couple to electronic lock cylinder 106; Be used for the display screen 109 that the prompting user imports random cipher, it for example can be LCD display, after first controller, 101 checking phone numbers and short message content success, display screen 109 shows " Please input the password ", and first controller 101 generates random cipher and sends to user mobile phone by gsm module 103 then; Be used for showing the LED lamp group 110 of electronic lock cylinder 106 states, when electronic lock cylinder 106 is unblanked, show the shape of unblanking, when electronic lock cylinder 106 shuts state, show to shut shape; Power supply 111 provides suitable electric energy to each circuit module of electronic lock.

Particularly, first controller 101 and second controller 102 of electronic lock of the present invention are respectively the STC89C51 single-chip microcomputer, and those skilled in the art also can select single-chip microcomputer or the programmable logic controller (PLC) of other types for use.The RXD pin of first controller 101 is couple to the TXD pin of gsm module, and the TXD pin of first controller 101 is couple to the RXD pin of gsm module.The RXD pin of second controller 102 is couple to the TXD pin of fingerprint instrument 105, and the TXD pin of second controller 102 is couple to the RXD pin of fingerprint instrument 105.The pin 1 of first relay 107 is couple to the P2.7 pin of first controller, and the negative pole of first relay 107 is couple to the negative pole of electronic lock cylinder 106.The pin 1 of second relay 108 is couple to the P2.7 pin of second controller 102, and the negative pole of second relay 108 is couple to the negative pole of electronic lock cylinder 106.Keyboard 104 among Fig. 1 is matrix keyboard, and the P1.0 pin that 6 pins of matrix keyboard are couple to first controller 101 respectively is to the P1.6 pin, and those skilled in the art also can select for use the keyboard of other types to realize the function of random cipher input.8 pins of LCD display 109 are couple to the P2.0 pin of first controller 101 respectively to the P2.7 pin.On first controller 101 that the positive pole of LED lamp group 110 is couple to respectively and the P1.7 pin of second controller 102.
