Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Fig. 1 is a schematic structural diagram illustrating an electronic key according to an exemplary embodiment. As shown in FIG. 1, the electronic key includes a key shank 10, and a key rod 20 connected to the key shank.
The outer surface of the key handle 10 is provided with an information acquisition device 11, the inside of the key handle is provided with a control device (not marked in the figure), and the control device is respectively connected with the information acquisition device 11 and the key rod 20.
When the electronic key is inserted into the electronic lock, the information acquisition device 11 acquires human body characteristic information;
if the collected human body characteristic information belongs to preset lock operation information, the lock operation information is sent to a control device, and the lock operation information at least comprises locking operation information and unlocking operation information;
the control device determines the encrypted information of the electronic lock corresponding to the lock operation information, and controls the key rod 20 to rotate according to the encrypted information to complete the locking or unlocking operation;
wherein, the encrypted information at least comprises the rotation direction of the key rod and/or the rotation number of the key rod.
In this embodiment, the information acquisition device 11 disposed on the outer surface of the spoon handle 10 may have a function of acquiring the characteristic information of the human body. Thus, the information-collecting device may include various sensors. Such as a fingerprint collector, a voiceprint collector, etc. Accordingly, the collected human characteristic information may also include a variety of information. Such as fingerprint information, voice print information, etc.
In this embodiment, the encrypted information determined by the control device corresponds to the lock operation information and the electronic lock. That is, the encrypted information determined by the control device corresponds to the acquired lock operation information, and the encrypted information corresponds to the electronic lock into which the electronic key is currently inserted.
When the lock operation information acquired by the information acquisition device 11 is the locking operation information, the encryption information of the electronic lock corresponding to the locking operation information may be generated in a preset manner. When the lock operation information acquired by the information acquisition device 11 is the unlocking operation information, the encryption information of the corresponding electronic lock can be inquired and acquired. The preset manner for generating the encryption information may include various manners. For example, the encryption information may be generated according to a preset fixed encryption algorithm, or may be randomly generated. The randomly generated encryption information may be validated throughout the locking and corresponding unlocking process.
In addition, since the encrypted information at least includes the rotation direction of the key rod and/or the number of rotation turns of the key rod, the control device can control the rotation of the key rod 20 according to the encrypted information, and the rotation mode of the key rod 20 can include various modes. For example, the key rod can be controlled to rotate clockwise or counterclockwise along the central axis of the key rod according to the encrypted information. The key rod can also be controlled to rotate for a set number of turns along the central shaft of the key rod according to the encrypted information. Wherein, the value of the set number of turns can be positive number. When the key rod is controlled to rotate for the set number of turns, any point on the key rod can be used as a reference point, and the key rod is controlled to rotate for the set number of turns by taking the reference point as a reference. The key rod can also be controlled to rotate clockwise or anticlockwise for a set number of turns along the central axis of the key rod according to the encrypted information. The key rod can also be controlled to rotate clockwise for a first set number of turns along the central axis of the key rod according to the encrypted information, and then rotate anticlockwise for a second set number of turns, and the like.
As can be seen from the above description, in the technical solution of this embodiment, the encryption information corresponding to the locking or unlocking operation is determined by collecting the human body characteristic information corresponding to the electronic key, so as to implement the locking or unlocking operation. In other words, in this embodiment, different pieces of human body characteristic information correspond to different pieces of encryption information, which embodies a personalized encryption mode of the electronic key and enhances the encryption security of the electronic key. In addition, the locking or unlocking operation based on the encrypted information is performed by controlling the rotation of the key rod of the electronic key, that is, the random encryption of the electronic key is realized by adopting a mechanical transmission method in the embodiment. In this encryption system, a plurality of combinations of encryption elements are included, so that the encrypted information is more secure and reliable.
The present embodiment further provides an electronic key, as shown in fig. 2, in which the key rod is a cylinder 20, the cylinder has at least one groove 21, and a protrusion 22 capable of adjusting the height according to the encrypted information is disposed in the groove.
The control device confirms the encryption information of the electronic lock that the lock operation information corresponds, and according to encryption information control key pole rotation, include:
when the control device determines the encrypted information of the electronic lock corresponding to the lock operation information, the height of the bulge on the key lever in the encrypted information is determined;
when the key rod is controlled to rotate according to the encrypted information, the control device controls the height of the bulge on the key rod to be the height of the bulge on the key rod in the encrypted information.
Wherein, a bulge is arranged in each groove.
When the spoon rod is provided with a plurality of bulges, the bulges can be uniformly distributed on the spoon rod or randomly distributed on the spoon rod. When the control device generates the encrypted information, the height of the protrusion on the key lever in the encrypted information may include the identifier of the protrusion and the corresponding height thereof. Thus, the heights of the bulges at different positions on the key rod can be controlled to be the same or different.
It can be seen that in the embodiment, at least one protrusion is arranged on the key rod, the height of the protrusion on the key rod is controlled through the encrypted information, and the encryption elements in the encrypted information are increased, namely, the formed information at least comprises any one of the rotation direction, the rotation number and the height of the protrusion of the key rod, so that the difficulty of cracking the encrypted information is increased, and the safety of the electronic key during locking is improved.
The embodiment also provides an electronic key, wherein an electromagnetic controller is arranged inside a key handle or a key rod of the electronic key, and the electromagnetic controller is respectively and electrically connected with the bulge and the control device;
the control device controls the height of the bulge on the key rod through the electromagnetic controller.
In this embodiment, the control device in the electronic key may control the electromagnetic on or off of the electromagnetic controller, so that the electromagnetic controller pushes the corresponding protrusion to a set position to change the height of the protrusion on the key lever. For example, the solenoid control may push the protrusion to the highest position when the solenoid control is electromagnetically turned on. I.e. the height of the protrusion on the spoon rod is highest at this highest position. When the electromagnetism of the electromagnetic controller is cut off, the electromagnetic controller can not push the bulge, and at the moment, the bulge can be restored to the original position. In this home position, the height of the projection on the spoon bar is at its lowest.
The embodiment increases the difficulty of cracking the encrypted information by controlling the height of the bulge on the key rod, and improves the safety of the electronic key during locking.
The embodiment also provides an electronic key, wherein an electronic lock identification module is also arranged in a key handle or a key rod of the electronic key, and the electronic lock identification module is connected with the control device;
when the electronic key is inserted into the electronic lock, if the human body characteristic information acquired by the information acquisition device belongs to preset unlocking operation information, the unlocking operation information is sent to the control device;
the control device acquires the encrypted information of the electronic lock corresponding to the unlocking operation information according to the electronic lock identified by the electronic lock identification module, and determines the decryption information corresponding to the encrypted information;
and controlling the key rod to rotate according to the decryption information to complete the unlocking operation.
When the control device acquires the encrypted information of the electronic lock corresponding to the unlocking operation information, the control device can inquire the locking operation information matched with the acquired unlocking operation information, and determine the encrypted information corresponding to the electronic lock according to the locking operation information. For example, when the collected unlocking operation information is fingerprint information for unlocking, the locking operation information based on the same fingerprint information may be inquired. And then inquiring the corresponding encryption information of the electronic lock according to the inquired locking operation information based on the same fingerprint information.
When determining the decryption information corresponding to the encrypted information, various manners may be included. For example, the decryption information may be determined using a decryption algorithm corresponding to the encryption algorithm that generated the encrypted information. The decryption information may be calculated in reverse from the encrypted information.
It can be seen that, in the embodiment, the reverse decryption operation is performed according to the encrypted information of the electronic lock corresponding to different lock operation information in the electronic key, so as to achieve the unlocking operation.
The embodiment also provides an electronic key, wherein in the electronic key, the electronic lock identification module identifies the electronic lock by adopting any one or more of the following modes:
radio frequency identification, near field identification, two-dimensional code scanning identification and Bluetooth identification.
In this embodiment, the electronic lock identification module can identify the electronic lock through identification operations in various ways. Therefore, when the same electronic key is used in a matching mode with a plurality of different electronic locks, the encryption information on different electronic locks corresponding to different lock operation information can be distinguished according to the electronic lock identified by the electronic lock identification module and the lock operation information acquired by the electronic key, and finally the function that the same electronic key can operate a plurality of different electronic locks is achieved.
Fig. 3 is a schematic diagram illustrating a configuration of an electronic key according to an exemplary embodiment. The electronic key includes a key shank 31 disposed at the rear end of the key, and a key rod 32.
The front and back sides of the key handle 31 are provided with a fingerprint identification chip 33, a control chip (not shown) arranged inside the key handle 31 and a forward and reverse rotating motor.
A plurality of height-controllable protrusions 34 are distributed on the spoon rod 32. The height of the bumps 34 can be controlled by the control chip via an electromagnetic controller.
The protrusion 34 shown in the figures can also be implemented by a telescopic rack. For example, the electronic key shown in fig. 4 can be connected with a motor in a way of embedding a gear combination in the key rod so as to control the height of the telescopic rack. The number of the telescopic racks can also be one or more. The telescopic racks can be uniformly distributed or randomly distributed on the spoon rod.
When the electronic key is inserted into the electronic lock for use, the fingerprint identification chips on the front and back planes of the key handle can collect the fingerprint of a user. The control chip in the key handle performs encryption locking or unlocking operation on the electronic lock according to the acquired fingerprint information and encryption information (such as height information of a protrusion on the key rod, rotation direction of the key rod, rotation number and the like) corresponding to the electronic lock generated by historical operation. Each locking or unlocking can be performed with data synchronization with the smart phone (or other mobile peripherals, such as PDA devices, tablet computers, etc.). In this way, a pair of electronic keys can be paired with different electronic locks installed at different locations in a home environment via a smartphone (or other mobile peripheral, such as a PDA device, a tablet computer, etc.).
In this embodiment, the process of using the electronic key is as follows:
the user defines the unlocking surface and the locking surface of the electronic key (namely, one surface selected from two surfaces of the key handle is the locking surface, and the other surface is the unlocking surface) through the smart phone (or other mobile peripherals, such as PDA equipment, tablet personal computer and the like). When locking or unlocking operation is carried out, only the corresponding locking surface or unlocking surface is required to be upward, and the fingerprint is pressed to be identified by the electronic key, so that the locking (or unlocking) program is automatically activated. The user can configure the start instruction of locking and unlocking. The smart phone can communicate with the electronic key through the built-in wireless communication module of the electronic key.
After the first activation, the key rod of the electronic key can be rotated based on the randomly generated encrypted information (wherein the angle, the number of turns and the rotating direction are all determined by the randomly generated encrypted information) and simultaneously control the heights of the protrusions at a plurality of positions in different directions. The control chip in the key handle generates encrypted information based on data calculation, and controls the motor to operate according to the encrypted information, the motor drives the key rod to rotate, and the height of the bulge on the key rod is controlled. Correspondingly, the lock cylinder of the electronic lock can be provided with different ring layers and the same ring of telescopic strips which are overlapped in an array mode and surround the electronic key, so that locking is realized. It can be seen that the present exemplary embodiment employs big data computing in conjunction with mechanical transmission to achieve random encryption, resulting in a higher security level for electronic-capable keys than for ordinary keys.
At the moment, in the locking process of the electronic key, an encryption program can be randomly generated according to the collected fingerprint information and historical operation, and the opening and closing state of the electronic lock is controlled by matching with the ring tooth array of the electronic lock and the height change of the protrusion. Therefore, the electronic lock locked by using the electronic key can only be unlocked by the electronic key, and other keys cannot know the position information of the protrusions (such as the number of the protrusions, the height of the protrusions and the positions of the protrusions) at all and cannot judge that the electronic lock is locked by rotating for several circles at the last time. The inside lock tooth of electronic lock at every turn can change along with the random encryption of electronic key, and the flexible change of lock tooth that corresponds in different circle positions, the flexible height that changes of different teeth of same circle are different, and the encryption level is very high, and only the encryption algorithm of electronic key own can save the last superposition secret numerical value that matches the electronic lock that locks of electronic key to the security level of electronic lock has been improved greatly.
When a user wants to pull out the electronic key, the user only needs to turn over the insertion surface of the key manually, the automatic locking function of the key is activated, the key rod of the electronic key rotates randomly again and is matched with the height of the control protrusion, and the electronic key automatically pops out after the locking operation is completed. When the electronic key is used next time, the key rod and the bulge of the electronic key can automatically rotate to the random position set in the last locking process only when the fingerprint information of the correct user is identified. Each time the lock is locked or unlocked, the smartphone end may have a synchronization record, as shown in fig. 5. Therefore, the front and back operation mode of the electronic key is simple and easy to use, and the user experience is improved.
When a user needs to open a certain electronic lock, the electronic key acquires the fingerprint of the user and then calls the encrypted information of the electronic lock which is stored in the electronic key and matched with the fingerprint of the user, and the electronic lock can be opened by the electronic key. The electronic key can identify the electronic lock through a built-in electronic lock identification function so as to call the encrypted information of the electronic lock configured with the user fingerprint in the electronic key. The electronic lock identification function can be realized by any one or more modes of radio frequency identification, near field identification, two-dimensional code scanning identification, Bluetooth identification and the like. Thus, when the electronic key approaches the electronic lock which is operated by over-locking, the history of the locking or unlocking operation of the electronic lock by using the electronic key can be rapidly identified, and the function of unlocking the electronic lock in different functional areas in a family by using one electronic key can be realized. According to the embodiment, historical operation records of the electronic key can be synchronized through the smart phone end, and matching operation of different electronic locks and the same electronic key in one family is achieved. The effect is shown in fig. 6. Therefore, the electronic key provided by the embodiment saves the number of the users using the electronic key, and simplifies the locking and unlocking operations.
In addition, the electronic key may further include a charging box that can charge the electronic key wirelessly or by wire, as shown in fig. 7.
Fig. 8 is a flowchart illustrating a control method of an electronic key according to an exemplary embodiment. As shown in fig. 8, the method includes the following operation steps:
step S801, when the electronic key is inserted into the electronic lock, human body characteristic information corresponding to the electronic key is collected;
step S802, when the collected human body characteristic information belongs to preset lock operation information, determining encryption information of an electronic lock corresponding to the lock operation information, wherein the lock operation information at least comprises locking operation information and unlocking operation information;
step S801, controlling the electronic key to rotate according to the encrypted information to complete locking or unlocking operation, wherein the encrypted information at least comprises the rotation direction of the key rod and/or the rotation number of the key rod.
The human body characteristic information corresponding to the electronic key may include a plurality of kinds of information. For example, fingerprint information pressed on the electronic key may be included. And may include voiceprint information of the user using the electronic key, and the like.
The preset lock operation information may include operation information, lock operation information and unlock operation information. For example, if the collected voice data is "lock," it may be considered that voiceprint information for locking is collected, and at this time, it may be determined that the collected human body feature information belongs to the locking operation information. Correspondingly, when the collected voice data is 'unlocking', the collected human body characteristic information can be determined to belong to unlocking operation information.
When the collected human body characteristic information belongs to the locking operation information, the encryption information of the electronic lock into which the electronic key is currently inserted can be generated according to a preset encryption algorithm or a random algorithm. When the collected human body characteristic information belongs to unlocking operation information, the locking operation information can be matched according to the unlocking operation information, and the encryption information of the electronic lock into which the electronic key is currently inserted is determined according to the matched locking operation information. The unlocking operation information and the locking operation information generated based on the same human body characteristic information are considered to be the unlocking operation information and the locking operation information matched with each other. For example, the unlocking operation information generated based on the fingerprint information is matched with the locking operation information generated by the same instruction information.
In this embodiment, the encrypted information at least includes the rotation direction of the key lever and/or the number of rotations of the key lever. The generation mode of the encrypted information and the control of the rotation operation of the key rod of the electronic key according to the encrypted information can refer to the corresponding contents of the electronic key. And will not be described in detail herein.
As can be seen from the above description, in the technical scheme of this embodiment, the encryption information corresponding to the locking or unlocking operation is determined by collecting the human body characteristic information corresponding to the electronic key, and the encryption operation is implemented in a mechanical transmission manner, so that the encryption security of the electronic key is enhanced.
The present embodiment further provides a method for controlling an electronic key, where the method further includes:
when the encrypted information of the electronic lock corresponding to the lock operation information is determined, the height of a bulge on the electronic key in the encrypted information is determined;
when the electronic key is controlled to rotate according to the encrypted information, the height of the protrusion on the electronic key is controlled to be the height of the protrusion on the key rod in the encrypted information.
In the embodiment, the raised height control information is added to the encrypted information, so that the security of the encrypted information is improved. Also, the number of the projections on the electronic key may be one or more. When there are a plurality of projections on the electronic key, the height control information of the projections included in the encrypted information may be the same or different height control information for the projections at different positions. Thus, the height control information of the protrusions on the electronic key may include various combinations of permutations. Thereby increasing the security of the encrypted information.
The present embodiment further provides a method for controlling an electronic key, where the method for controlling the height of a protrusion on the electronic key to be the height of the protrusion on the electronic key in the encrypted information includes:
the height of the control projection is the height of the projection in the encrypted information through an electromagnetic controller electrically connected with the projection on the electronic key.
In this embodiment, the height of the protrusion on the electronic key is controlled electromagnetically. For a specific control manner, reference may be made to the description content corresponding to the electronic key in the above embodiments, which is not described herein again.
In practice, the height of the protrusion on the electronic key can be controlled by other means, such as a gear set.
The embodiment also provides a control method of the electronic key, wherein in the method, the rotation of the electronic key is controlled according to the encrypted information to complete the unlocking operation, comprising the steps of;
when the electronic key is inserted into the electronic lock, if the collected human body characteristic information belongs to preset unlocking operation information, acquiring encryption information of the electronic lock corresponding to the unlocking operation information according to the electronic lock information identified in advance, and determining decryption information corresponding to the encryption information;
and controlling the electronic key to rotate according to the decryption information to complete the unlocking operation.
When the encrypted information of the electronic lock corresponding to the unlocking operation information is obtained, the locking operation information matched with the collected unlocking operation information can be inquired, and the encrypted information corresponding to the electronic lock is determined according to the locking operation information. For example, when the collected unlocking operation information is voiceprint information for unlocking, the locking operation information based on the same voiceprint information may be inquired. And then inquiring the corresponding encryption information of the electronic lock according to the inquired locking operation information based on the same voiceprint information.
When determining the decryption information corresponding to the encrypted information, various manners may be included. For example, the decryption information may be determined using a decryption algorithm corresponding to the encryption algorithm that generated the encrypted information. The decryption information may be calculated in reverse from the encrypted information.
It can be seen that, in the embodiment, the reverse decryption operation is performed according to the encrypted information of the electronic lock corresponding to different lock operation information in the electronic key, so as to achieve the unlocking operation.
The present embodiment further provides a method for controlling an electronic key, where the method further includes:
the electronic lock information is identified by adopting any one or more of the following modes:
radio frequency identification, near field identification, two-dimensional code scanning identification and Bluetooth identification.
In this embodiment, through the electronic lock recognition function, the electronic lock corresponding to the current lock operation can be recognized. For example, in the locking operation, the encryption information of the electronic lock corresponding to the locking operation information may be stored by the recognized electronic lock information. Accordingly, during unlocking operation, the encrypted information of the electronic lock corresponding to the locking operation information matched with the unlocking operation information can be inquired through the identified electronic lock information.
Therefore, when the same electronic key is used in a matching mode with a plurality of different electronic locks, the encryption information on different electronic locks corresponding to different lock operation information can be distinguished according to the electronic lock identified by the electronic lock identification module and the lock operation information acquired by the electronic key, and finally the function that the same electronic key can operate the plurality of different electronic locks is achieved.
Fig. 9 is a flowchart illustrating a control method of an electronic key according to an exemplary embodiment. As shown in fig. 9, the control process of the electronic key includes the following steps.
In step S901, an electronic key is inserted into an electronic lock, and first fingerprint information is detected by a fingerprint acquisition part for unlocking operation provided on a surface of a key shank of the electronic key;
in step S902, if the first fingerprint information matches with the second fingerprint information stored in advance, acquiring encryption information corresponding to the second fingerprint information;
in step S903, the key lever is controlled to rotate and the height of the protrusion on the key lever according to the acquired encryption information to complete the unlocking operation.
In the above method, the encrypted information may include key lever rotation information for controlling rotation of the key lever. For example, the key lever rotation information may include the number of turns of the key lever, and whether the direction of the key lever rotation is clockwise or counterclockwise. When the number of turns is not an integer, the number of turns can also include a turning angle, i.e., how many turns are turned after the integer turns. Wherein, the rotation of the key rod can be controlled firstly, and then the height of the bulge on the key rod can be controlled. The height of the bulge on the key rod can be controlled while the key rod is controlled to rotate.
In the method, the process of storing the second fingerprint information and the unlocking information corresponding to the second fingerprint information in advance may refer to the following method:
detecting fingerprint information for locking through a fingerprint acquisition component for locking operation on the surface of the key handle, and storing the fingerprint information for locking as second fingerprint information;
when the locking operation is controlled, the generated encryption information is stored as encryption information corresponding to the second fingerprint information.
In practical applications, the process of storing the second fingerprint information and the encryption information corresponding to the second fingerprint information in advance may be considered as a locking process of the electronic key, and in this case, the locking process may be performed by a predefined unlocking surface and a predefined locking surface on the key handle. That is, the user can consider the user fingerprint information collected by the fingerprint collection unit provided on the upper surface, which is the user fingerprint for locking, to correspond to the second fingerprint information described above, with the upper surface defined in advance facing upward. Correspondingly, the electronic key can randomly generate corresponding encrypted information for the user fingerprint information, and the locking operation can be completed by controlling the rotation of the electronic key and the height of the bulge according to the generated encrypted information.
Aiming at the requirement of the safety of the electronic lock, the one-time encryption information can be generated aiming at the locking and unlocking processes each time. Namely, after the encryption information is generated in the one-time locking process, once the unlocking operation is completed according to the encryption information, the encryption information is immediately invalid. When locking is performed again, new encryption information is regenerated.
In this example, the electronic key may also receive a user-initiated encryption operation of multiple electronic locks, that is, the same electronic key may be paired with multiple different electronic locks. At this time, only the encrypted information of the electronic lock generated by the historical operation of each electronic lock needs to be stored, and the encrypted information of different electronic locks may be the same or different. Therefore, when the electronic key receives unlocking operation which is initiated by a user and aims at a certain electronic lock, the encrypted information generated by the historical operation corresponding to the electronic lock is obtained, the key rod of the electronic key is controlled to rotate correspondingly according to the encrypted information, and the height of the bulge is controlled, so that the electronic lock can be opened.
