Description
Technical field
The utility model relates to a kind of emergent unlocking device of electronic lock, especially a kind of electronic lock emergent unlocking device and decode controller thereof of code.
Background technology
At present, known electronic lock (coded lock, TM kayser, IC card lock, RF kayser, Fingerprint Lock etc.) all can't be used electronic key unlocking when electron key (password, TM card, IC-card, RF card, fingerprint etc.) is all lost or damaged, so for emergent unlocking, generally to join the standby mechanical lock of a cover in addition, this just makes the theftproof performance of electronic lock be pulled down to the level of mechanical lock, and this is the common problem that present electronic lock runs into.
The utility model content
The purpose of this utility model is in order to solve the problem of electronic lock emergent unlocking, a kind of electronic lock emergent unlocking device and decode controller thereof of code to be provided, and it can be issued to the purpose of emergent unlocking in the condition that does not reduce the electronic lock theftproof performance.
For achieving the above object, the technical scheme of the utility model electronic lock emergent unlocking device is as follows:
It comprises a coding circuit, cipher inputting keyboard, output plug and battery BAT, and the coding output of described cipher inputting keyboard and the parallel input port of coding circuit join, the joining of the serial output terminal of described coding circuit and output plug.
The further improved technical scheme of described electronic lock emergent unlocking device is as follows
Described output plug is a three-prong plug, and the serial output terminal of one of them port and coding circuit joins, and positive pole and the negative pole of two other port and described battery BAT join.
The technical scheme of the utility model decoder is as follows:
It comprises the input socket that cooperates with output plug, decoder and an output driving circuit, the coding input of described input socket and the decoding input of described decoder join, and the decoding output of described decoder and the input of output driving circuit join.
The further improved technical scheme of described decoder is as follows:
Decoding input at described decode controller is connected to a RC anti-jamming circuit.
Characteristics of the present utility model are to adopt the mode of encoding and decoding to carry out emergent unlocking, the user sets up an emergent unlocking password on their own with the emergent unlocking device earlier in advance, and with this emergent unlocking cipher memory in decode controller, during emergent unlocking, the user can directly insert corresponding emergent unlocking socket with the emergent unlocking device, then decode controller compares the password of emergent unlocking device input with the password of setting in advance, promptly exports a unlocking signal after the unanimity, and electronic lock can be opened.Emergent unlocking device of the present utility model is equivalent to the electronics standby key of a code, and the user can be provided with the emergent unlocking password voluntarily, and is safe and reliable.Find out that thus the utility model has been realized emergent unlocking under the prerequisite that does not reduce the electronic lock theftproof performance, solved the emergent unlocking problem of electronic lock preferably.
Description of drawings
The circuit theory diagrams of Fig. 1, emergent unlocking device.
The circuit theory diagrams of Fig. 2, decode controller.
The specific embodiment
Referring to Fig. 1, should comprise coding circuit 1, cipher inputting keyboard 2 and an output plug 3 one by one by anxious lockaid gun, has the gear on-off that 12 hands are dialled on the described cipher inputting keyboard 2, a gear on-off can provide high, medium and low three kinds of states, therefore, this cipher inputting keyboard 2 can provide 3
12Plant different passwords, the parallel input port A0~A11 of its coding output 1-12 pin and coding circuit 1 joins, and the serial output terminal DOUT of described coding circuit 1 and the DATA of output plug 3 end join.
Referring to Fig. 2, this decode controller comprises the input socket 4, decoder 5 and the output driving circuit 7 that match with described output plug 3, the coding input DATA of the decoding input RFIN of described decoder 5 and described input socket 4 joins, and the decoding output D1 of described decoder 5 and the input of output driving circuit 7 join.This decode controller and electronic lock are installed together, and it is provided with the normal lockaid gun of electronic lock is parallel, the output of its output and the normal lockaid gun of electronic lock by one or 8 and the actuating station VOUT that unblanks join.For anti-interference, be connected to a RC anti-jamming circuit that is connected into by resistance R 9 and capacitor C 2 at the decoding input RFIN of described decoder 5.
The course of work of emergent unlocking is: referring to Fig. 1, the user is provided with the emergent unlocking password by cipher inputting keyboard 2 earlier, promptly stir 12 gear on-offs and set a password, this password is transformed into 12 binary codes by cipher inputting keyboard 2, send in the coding circuit 1 by its LPT then, send into output plug 3 by the serial end of coding circuit 1 again, by output plug 3 outputs, press the memory button S1 among Fig. 2 then, with the input socket 4 that the output plug among Fig. 13 inserts among Fig. 2, then the emergent unlocking password of user's setting is sent among Fig. 2 and is remembered in the decoder 5; During emergent unlocking, the emergent unlocking device is inserted the emergent unlocking socket of electronic lock, it is the input socket 4 that the output plug 3 among Fig. 1 inserts among Fig. 2, then the user is provided with password in advance and is input in the decoder 5, decoder 5 compares with the password of its memory in advance, if consistent, then from unlocking signal of its decoding output D1 output, this unlocking signal by drive circuit 7 and or door 8 backs from the output of VOUT end, deliver to the actuator of unblanking and carry out and unblank.
Again referring to Fig. 1, in order to prevent the dead battery (as regularly not changing battery or going out for a long time) in the decode controller and can't unblank, described output plug 3 is a three-prong plug, the serial output terminal DOUT of one of them port DADA and coding circuit 1 joins, and positive pole and the negative pole of two other port VCC, GND and described battery BAT join.Like this, just can provide power supply for the decode controller among Fig. 2 with the battery of emergent unlocking device; Referring to Fig. 2, same again, the corresponding dual power supply circuit that is provided with in decode controller, the battery BAT1 of this dual power supply route decode controller or door 9 and stabilizator 6 constitute.When if the battery BAT1 of decode controller can't power, the power supply that the emergent unlocking device provides by socket 4 can by or door 9 be added on the stabilizator 6, then decoder 5 can operate as normal and realize unblanking.
