Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the drawings and examples, but the scope of the present invention should not be limited thereto.
FIG. 1 is a schematic structural diagram of an RNA-encoded-imitation laser anti-theft lock according to a preferred embodiment of the present invention. FIG. 2 is a schematic structural diagram of a key and a control module of the laser anti-theft lock with RNA-like code according to the preferred embodiment of the invention.

FIG. 4 is a schematic diagram of encoding and decoding of the laser anti-theft lock with RNA-like encoding according to the preferred embodiment of the invention.
As shown in fig. 1, the antitheft lock of the present invention comprises: the key I is used for generating a group of ordered optical pulse code signals; the control module II is used for receiving the optical pulse password signal and converting the optical pulse password signal into an electrical pulse password signal, the electrical pulse password signal is further converted into a digital password and then compared with a preset password, if the digital password is consistent with the preset password, an unlocking signal is output, and otherwise, the unlocking signal is not output; the lock head 5 is used for opening or locking the anti-theft lock according to the unlocking signal of the control module II; and the power supply 6 is used for supplying power to the key I and the control module II.
The key I includes a drive circuit 1 and a light pulse array 2. In this embodiment, the optical pulse array 2 is composed of 4 (n is 4) laser diodes, and the driving circuit 1 drives the optical pulses according to a preset passwordThe array 2 generates a light pulse code signal. The driving circuit encodes a series of codon signals according to the preset password, encodes each codon into m ordered optical pulses, outputs the ordered optical pulses to the corresponding laser diodes in sequence, and drives each laser diode to generate m ordered optical pulse password signals. Specifically, the predetermined code consists of a series of codons, each of which contains m (e.g., m-3 in this embodiment) ordered electrical pulse code signals, each of which has 64 combinations (4)364). These 3 ordered electrical pulse code signals of a codon are sent to the designated laser diodes (e.g., the 1 st laser diode, the 2 nd laser diode, and the 4 th laser diode, as described in detail below) in the optical pulse array 2 in a predetermined order, so as to drive the optical pulse array 2 to generate an ordered optical pulse code signal (i.e., a combination of 3 ordered optical pulses). A series of ordered light pulse code signals (i.e., a combination of a plurality of the light pulses) is generated based on a series of codons. There is a certain time interval between the ordered optical pulse code signals, i.e. between every 3 ordered optical pulse combinations. The control module II comprises a detector array 3 and a signal processing module 4. In this embodiment, the detector array 3 has 4 photodiodes, and after the key I is inserted into the lock hole of the lock cylinder, the photodiodes in the detector array 3 correspond to the laser diodes in the optical pulse array 2 in mechanical positions one by one.
The detector array 3 receives a series of sequential optical pulse code signals sequentially generated by the designated laser diodes in the optical pulse array 2, and the photodiodes in the detector array 3 convert the series of sequential optical pulse code signals into a series of sequential electrical pulse code signals. Similarly, each of the ordered electrical pulse cipher signals is composed of 3 ordered electrical pulses and enters the signal processing circuit 4 for decoding. When decoding, 3 ordered electric pulses can be converted into 3 corresponding numbers, namely digital passwords, by the signal processing circuit 4 in sequence, if the digital passwords are consistent with preset passwords, the signal processing circuit 4 can output unlocking signals, if the digital passwords are inconsistent with the preset passwords, the unlocking signals cannot be output, and when the unlocking signals are not output, the lock head is in a normally closed stateState. It should be mentioned that the coding method of the present invention adopts the RNA-imitated coding, when n is 4 and m is 3, each codon has 64 forms, and the key amount generated in 0.1 second reaches 64 for the typical pulse with 1KHz repetition frequency100Therefore, the anti-theft lock has extremely high safety and irreproducibility.
Referring to fig. 2, a key I and a control module II correspond to the key I and the control module II in fig. 1, in the present invention, the key does not have a power supply, the power supply 6 is connected to the signal processing circuit 4 to supply power to the control module II, the power supply has a charging interface 11, and the charging can be performed through the charging interface 11 when the battery power is low. The power supply 6 supplies power to the drive circuit 1 of the key I through the needle type interface 12, the needle type interface is located in a lock hole of the lock head 5, and when the needle type interface 12 is in no-load or short circuit, the control module II does not work. When the unmatched key I is inserted, the pin interfaces of the key and the power supply are not matched, so that the control module cannot be triggered to work. By arranging the needle type interface, energy can be saved, the working time of the battery can be prolonged, and the safety of the anti-theft lock and the hard copying property of the key are further improved. In addition, the key is also provided with a standby power supply interface 13, if the anti-theft lock is idle for a long time, the electric quantity of the battery is exhausted and the battery is not charged in time, and a power supply such as a charger can be used for charging immediately through the standby power supply interface.
Referring to fig. 3 again, the signal processing circuit 4 is preset with a reference interval of the electric pulse cipher signal intensity (e.g. [ a ]1，A2]) The signal processing circuit 4 receives the ordered electrical pulse code signal from the detector array 3 and compares the intensity of the electrical pulse code signal with a preset reference interval [ A ]1，A2]And (6) comparing. If the keys are not matched, the pulse intensity is too large or too small and is not within the preset reference interval range, and the signal processing circuit can directly ignore the pulse intensity. If the intensity of the electrical pulse cipher signal entering the signal processing circuit 4 meets the preset reference interval range, the subsequent decoding operation is performed. This reduces the mismatching rate and further improves the security of the anti-theft lock of the invention.
Furthermore, the anti-theft lock of the invention requires that the photodiodes of the detector array and the laser diodes of the optical pulse array must meet the requirement of one-to-one correspondence of mechanical positions and matching of central response wavelengths. If the keys are not matched, on one hand, the geometrical positions of the light pulse array and the detector array are not matched, so that the intensity of the coded signal pulse detected by the detector array is insufficient and does not meet the preset reference interval of the intensity of the electric pulse coded signal. On the other hand, the inconsistency of the central response wavelengths can reduce the detection efficiency of the detector array, and the detected pulse intensity of the coded signal can not meet the preset reference interval of the electric pulse coded signal intensity. That is, the constraint that the mechanical positions of the detector array and the optical pulse array match the central response wavelength may further enhance the security of the anti-theft lock of the present invention and the hard-to-duplicate nature of the key.
Therefore, as mentioned above, the ultra-large amount of keys and the strict limitation of the pulse signal intensity are enough to ensure that the laser anti-theft lock with the RNA-like code has higher security and the key is difficult to copy.
The coding and decoding process of the laser anti-theft lock with the RNA-like code according to the embodiment of the invention is described below with reference to FIG. 4. In the protein translation process, A, C, G, U kinds of bases are used as codons, and a promoter is also present as a codon on mRNA. In the embodiment of the present invention, 4 pairs of laser-photodiodes in the light pulse array and the detector array are respectively labeled as 1,2,3, and 4, that is, the codons consist of 1 to 4, 4 numbers. Similar to the protein translation process, the codon of the present invention also has a promoter, for example, if the promoter is 124, the laser diode 1, the laser diode 2 and the laser diode 4 sequentially generate an optical pulse password signal, then the photodiode 1, the photodiode 2 and the photodiode 4 sequentially detect the optical pulse password signal, then convert the detected ordered optical pulse password signal into an ordered electrical pulse password signal and transmit the ordered electrical pulse password signal to the signal processing circuit, the signal processing circuit sequentially receives the electrical pulse signals from the photodiodes 1,2 and 4 and records the electrical pulse signals as the digital password 124, and only if the signal processing circuit obtains the promoter signal (the digital password 124), the subsequent decoding operation is started.
If the signal processing circuit receives the starting sub-signal, the following password signal is received and processed. Assuming that the preset password is 314421123132124 … …, first, the driving circuit drives the laser diode 3, the laser diode 1 and the laser diode 4 to sequentially generate an optical pulse password signal after a time interval (μ s-ms) to form a codon 314, and then generates a codon 421 after the same time interval, and so on, the optical pulse array generates a series of ordered codons 314421123132124 … …, and at the same time, the detector array sequentially converts the codons into electrical pulse password signals, and the signals are decoded into a digital password 314421123132124 … … by the signal processing circuit. In the encoding and decoding process of the laser anti-theft lock, a codon with repeated numbers, such as 223, can also be generated, firstly, the driving circuit drives the laser diode 2 to continuously generate two optical pulse code signals, then the laser diode 3 is driven to generate one optical pulse code signal, the 3 optical pulse code signals form one codon 223, then the next codon is encoded after a time interval (mu s-ms), similarly, the driving circuit drives the laser diode 2 to continuously generate 3 optical pulses to generate the codon 222, and meanwhile, the detector array converts the codes into the electric pulse codes and decodes the electric pulse codes into the corresponding digital codes 223, 222 and the like by the signal processing circuit.
In the protein translation process, a terminator also exists in a codon on mRNA, in the invention, for example, if the terminator is 322, a driving circuit drives a laser diode 3 to generate one light pulse, then drives a laser diode 2 to continuously generate two light pulses, the 3 light pulses form the codon 322, then the photodiode 3 and the photodiode 2 of a detector array sequentially detect 1 and 2 light pulses respectively, then the light pulse password signal is converted into an electric pulse password signal and transmitted to a signal processing circuit, and the signal processing circuit sequentially receives the electric pulse password signal and records the electric pulse password signal as a digital password 322. In the decoding process, after the signal processing circuit of the control module starts decoding, each generated codon is compared with a preset codon, if the codon is consistent with a preset password, the next decoding operation is carried out, if the codon is inconsistent with the preset password, a prompt tone is sent out, and when the signal processing circuit obtains a terminator signal (a digital password 322), the decoding is stopped, and an unlocking signal is output to the lock head.
The working process of the laser anti-theft lock with RNA-like code according to the embodiment of the invention is described below with reference to FIGS. 2,3 and 4. Assume that the predetermined code is 124314421123132124 … … 322, where the promoter is 124 and the terminator is 322. When a corresponding key I is inserted into a lock hole, one end of a needle type interface 12 on the key I is in contact with the other end of a matched needle type interface 12 in the lock hole, the key I is electrified, a driving circuit 1 on the key I starts to encode laser pulses according to a preset password, a promoter signal is encoded firstly, the driving circuit 1 drives laser diodes 1,2 and 4 of an optical pulse array 2 to sequentially generate 3 optical pulses, then a detector array 3 sequentially receives the 3 optical pulses, converts the optical pulses into the electric pulses and transmits the electric pulses to a signal processing circuit 4, the signal processing circuit 4 detects whether the pulse intensity is in a preset reference interval, and if so, the pulse intensity is converted into a digital password and identifies the promoter. After the drive circuit 1 encodes the promoter, a codon signal is encoded every time an interval (μ s-ms) passes, and the codons 314421123132124 … … are sequentially encoded, meanwhile, the signal processing circuit 4 sequentially recognizes the codons 314421123132124 … …, and the signal processing circuit 4 compares the codons with the preset codons every time the codons are recognized, if the codons are consistent, the next decoding operation is carried out, and if the codons are inconsistent, a prompt tone is given. After the drive circuit 1 finishes coding the preset codon, the coding of the terminator is started, similarly, the drive circuit 1 drives the laser diode 3 to generate one optical pulse, then drives the laser diode 2 to continuously generate two optical pulses, the signal processing circuit 4 recognizes a terminator signal (digital code 322), stops decoding and outputs an unlocking signal to the lock head, the lock head receives the unlocking signal to unlock, and when the unlocking signal is not received, the lock head is in a locking state.
The RNA-imitated coded laser anti-theft lock of the embodiment of the invention uses 4 (species) laser diodes in a light pulse array, and each codon contains 3 ordered light pulse signals which are similar to codons consisting of 4 bases in protein translation and 3 bases of tRNA. In accordance with the teachings of the present invention, the use of 5 or more laser diodes, and the use of a coding format with 4 or more codons, are within the scope of the practice of the present invention.
