Below by embodiment, technical scheme is further elaborated.
Embodiment 1
A kind of electronics key by voice-grade channel transmission password, including electronics secret key and electronic lock body, described electronics is close
Spoon is intelligent terminal, and described electronic lock body includes lock body power supply, audio jack, controlled power supply circuits, E-token dynamic password card, data pair
Than module, single-chip microcomputer and open locking execution unit；
The L channel of described audio jack is connected to controlled power supply circuits, and lock body power supply is data by controlled power supply circuits
Contrast module, single-chip microcomputer single-chip microcomputer and open locking execution unit are powered；
The R channel of described audio jack is connected to Data Comparison module and E-token dynamic password card, dynamic mouth by data cable
Token is connected to Data Comparison module by data cable again,
When unblanking, audio jack is inserted in the earpiece holes of intelligent terminal.
Described Data Comparison module includes high level AND circuit, low level AND circuit and OR circuit,
Described high level AND circuit and low level AND circuit are in parallel, and connect with OR circuit simultaneously, or door
Circuit is connected serially to single-chip microcomputer again, the R channel of described audio jack by data cable be connected simultaneously to high level AND circuit and
Low level AND circuit.
Described intelligent terminal stores dynamic password number based on time synchronized with the E-token dynamic password card in electronic lock body
According to.
A kind of method by voice-grade channel transmission cipher control open locking, comprises the steps:
(1) lock body power supply, audio jack, controlled power supply circuits, E-token dynamic password card, Data Comparison mould are included in electronic lock body
Block, single-chip microcomputer and open locking execution unit, remote server is pressed based on time synchronized with the E-token dynamic password card in electronic lock body
Current binary system unlocking cipher is calculated according to algorithm set in advance,
(2), when preparing to unblank, by intelligent terminal to remote server acquisition request unlocking cipher, validated user is received
After request, remote server binary system unlocking cipher followed by parity check code being sent on intelligent terminal；
(3) intelligent terminal for reception is to after unlocking cipher, judges that unlocking cipher is the most effective by even-odd check, close when unblanking
When code is effective, intelligent terminal adds section head identification code before effective unlocking cipher, and reconvert becomes audio file, described audio frequency literary composition
When part is play, the high level signal that L channel continuously sends out, R channel sends and carries out, according to binary system unlocking cipher, the ripple that encodes
Shape is square wave or the signal of telecommunication close to square wave；
(4) audio jack of electronic lock body being inserted in the earpiece holes of intelligent terminal, intelligent terminal opens after regulating volume
Begin to play audio file, during broadcasting,
The high level signal that L channel continuously sends out triggers controlled power supply circuits so that lock body power supply is by controlled power supply electricity
Road is that Data Comparison module, single-chip microcomputer single-chip microcomputer and open locking execution unit are powered, and electronic lock body is transferred to work by standby,
The waveform carrying out encoding according to binary system unlocking cipher is square wave or the signal of telecommunication close to square wave by R channel
Transmit the contrast module to electronic lock body and E-token dynamic password card, after E-token dynamic password card recognizes unlocking cipher section head identification code,
To the binary system unlocking cipher that contrast module input is built-in, built-in binary system unlocking cipher is opened with the binary system that R channel inputs
Lock cipher signal of telecommunication step-by-step is compared, and when the two is identical, Single-chip Controlling open locking execution unit is unblanked, when the two
Time incomplete same, do not unblank.
(5) after singly unblanking, extracting audio frequency rubbing head, power supply circuits lose high level and trigger so that lock body power supply stops
Power for Data Comparison module, single-chip microcomputer single-chip microcomputer and open locking execution unit, recover holding state.
Embodiment 2
The binary number that unlocking cipher is 32 bit lengths that the present embodiment design uses, password a total of 232=
4294967296 kinds, intelligent terminal is mobile phone.Mobile phone sends the principle of password for utilizing audio frequency to export analog and digital signal.Mobile phone
Earpiece holes generally have four contacts, respectively L channel, R channel, mike and common cathode.It is used herein L channel, the right side
Sound channel and common cathode these three contact.
L channel continuously sends out the high level signal of 1v and triggers controlled power supply circuits so that lock body power supply is by controlled power supply
Circuit is that Data Comparison module, single-chip microcomputer single-chip microcomputer and open locking execution unit are powered, and electronic lock body is transferred to work by standby,
The waveform carrying out encoding according to binary system unlocking cipher is square wave or the signal of telecommunication close to square wave by R channel
Transmit to electronic lock body, the content such as following table of a unlocking cipher signal data bag:
A length of 50 milliseconds of code content every, it is 150 milliseconds that packet section head identification code accounts for three bit lengths, every number
It is 1750 milliseconds according to bag total length, when a binary code is 1, the high level of output 1v, when a binary code is 0,
The low level of output 0v.The binary system unlocking cipher signal of telecommunication step-by-step that built-in binary system unlocking cipher and R channel input is successively
Compare, when the two is all high level, by high level AND circuit to or circuit output one high level pulse enter list
Sheet machine record, when the two is all low level, by low level AND circuit to or circuit output one high level pulse enter list
Sheet machine record, when being high level or low level when the two is different, export to single-chip microcomputer through OR circuit is low level pulse,
The number of times of single-chip microcomputer record high level pulse, if single-chip microcomputer counting reaches 32, exports high level, controls open locking enforcement division
Part is unblanked, if counting is less than 32, does not unblanks.Pulse signal is not had then to count zero more than 80 milliseconds.
