Description

Bicycle anti-theft system and bicycle unlocking method

technical field

The invention relates to a bicycle lock, in particular to a short-distance wireless-controlled bicycle lock and an unlocking method thereof.

Background technique

Most traditional bicycles use a physical key to be inserted into the lock cylinder to achieve the purpose of unlocking. Along with the increasingly popularization of the application of wireless control, also have the remote control unlocking scheme that is applied to bicycle to propose at present. Among them, there is a remote unlocking scheme in which the car lock is automatically unlocked when the remote control device is close to the car lock, and there is also a remote unlocking scheme in which the remote control device actively sends out an unlocking control signal, and the car lock is unlocked after receiving it. In an example of applying the former solution, the owner may only approach the bicycle, but not really want to use the bicycle. For example, the owner just takes a rest and sits through the window, but at this time the bicycle is unlocked and is at risk of being stolen. In an example of applying the latter solution, the remote control device is a smart phone, and the owner usually needs to enter the corresponding application program to unlock the bicycle. This unlocking operation is a bit cumbersome. In addition, in the current remote unlocking solution, a third party may also intercept and simply decipher the communication signal during the wireless communication between the remote control device and the car lock, and then be able to hack into the anti-theft system of the bicycle, putting the bicycle at risk of being stolen .

The first processor 102 can be connected to the telecommunication network 3 through the third wireless communication circuit 108, and then communicate with a remote end (for example, communication including voice and data). Wherein, the telecommunication network 3 can be regarded as a collection of a group of nodes (including terminals), and these nodes are connected through traditional links to enable communication between terminals. These nodes may use circuit switching, message switching or packet switching to send signals to the correct target terminal via the correct link and node. In practical applications, the telecommunication network 3 may include a computer network, the Internet, a telephone network (such as a public switched telephone network, a mobile telephone network), and the like.

The first electrical energy storage element 112 can provide required electrical energy to the first processor 102 and other electronic components. In practice, the first electrical energy storage element 112 can be a battery, such as but not limited to a secondary battery. In practical application, the first processor 102, the first memory 104, the first wireless communication circuit 106, the third wireless communication circuit 108, the first display and input interface 110 and the first electric energy storage element 112 can be fully or partially integrated to one or more board modules. In practical applications, the portable device 10 may be, but not limited to, a smart phone, a PDA (Personal Digital Assistant, PDA), a tablet computer, and the like.

In this embodiment, the controller 14 includes a second processor 142, a second memory 144, a second wireless communication circuit 146, a fourth wireless communication circuit 148, a second display and input interface 150, and a second electric energy storage element 152. The second processor 142 is electrically connected to the second memory 144 , the second wireless communication circuit 146 , the fourth wireless communication circuit 148 , the second display and input interface 150 and the second electric energy storage element 152 . The second processor 142 has functions such as processing data and controlling the operation of other electronic components, for example, it includes a processing unit, a control circuit, and a register. The second processor 142 can be connected to the telecommunication network 3 through the fourth wireless communication circuit 148, and then communicate with the remote end (at least including data communication). The second processor 142 can communicate with nearby devices through the second wireless communication circuit 146 , for example, through wifi, bluetooth and other communication protocols for short-distance communication. The second display and input interface 150 can be realized by a combination of a display screen (such as a liquid crystal display panel or an LED array) and an input keyboard (such as a numeric keypad), or can be realized by a single touch display panel. The second processor 142 can display messages to the user or receive input from the user through the second display and input interface 150 . The second processor 142 can access the content in the second memory 144 , the second memory 144 stores the second encrypted information, and the second encrypted information matches the first encrypted information stored in the first memory 104 . The second electric energy storage element 152 can provide required electric energy to the second processor 142 and other electronic elements, and the second electric energy storage element 152 can be implemented by a battery, such as but not limited to a secondary battery. In practical application, the second processor 142, the second memory 144, the second wireless communication circuit 146, the fourth wireless communication circuit 148, the second display and input interface 150, and the second electric energy storage element 152 can be all or part Integrate into one or more board modules. In addition, when the bicycle 2 has electronic components, the controller 14 may also be integrated into the electronic components as appropriate. For example, the bicycle 2 is driven by electric equipment, and the controller 14 can be integrated into the electric equipment. Moreover, the controller 14 can still be installed on the bicycle 2 as an independent device, for example fixed on the frame of the bicycle 2 .

In this embodiment, the lock 12 can lock the bicycle 2 so that the bicycle 2 cannot be moved, or can unlock the bicycle 2 to allow the bicycle 2 to move. In practical applications, the lock 12 has different locking and unlocking actions for the bicycle 2 through different types of locking mechanisms. For example, the lock 12 interferes with the rotation of the wheel with a structural member (for example, with a latch passing through the spokes, clamping the axle, etc.). Another example is when the bicycle 2 is driven by an electric system, the lock 12 can be a control circuit in the electric system or a switch coupled to the electric system, which can control whether the electric system works.

When the bicycle anti-theft system 1 is running, after the first processor 102 and the second processor 142 are connected via the first wireless communication circuit 106 and the second wireless communication circuit 146 for short-distance communication (such as a short-distance communication connection based on the Bluetooth protocol) The first processor 102 encrypts the notification signal according to the first encryption information and transmits the encrypted notification signal to the controller 14 via the first wireless communication circuit 106 . The second processor 142 receives the encrypted notification signal via the second wireless communication circuit 146 . The second processor 142 judges whether the encrypted notification signal is valid according to the second encrypted information. If the second processor 142 determines that the encrypted notification signal is valid, the second processor 142 generates a confirmation message. In practical applications, the second processor 142 can display the confirmation message through the second display and input interface 150, and the user can input a confirmation input through the second display and input interface 150 according to the confirmation message, as shown in FIG. 2 ( Wherein the second display and input interface 150 is represented by a dashed box, which includes a display screen 150a and a plurality of buttons 150b). Or the second processor 142 sends the confirmation message to the portable device 10 through the second wireless communication circuit 146, and the first processor 102 receives the confirmation message through the first wireless communication circuit 106 and transmits the confirmation message through the first display and input interface 110 The confirmation message is displayed, and the user can input the confirmation input through the first display and input interface 110 according to the confirmation message, as shown in FIG. 3 (wherein the first display and input interface 110 is a touch display panel, which simultaneously displays the Confirmation message and virtual keyboard, the user can enter through the virtual keyboard); then, the first processor 102 receives the confirmation input through the first display and input interface 110 and transmits the confirmation input through the first wireless communication circuit 106 to controller 14. When the second processor 142 receives the confirmation input via the second display and input interface 150 or via the second wireless communication circuit 146, the second processor 142 determines whether the confirmation input is valid. If the second processor 142 determines that the confirmation input is valid, the second processor 142 controls the lock 12 to unlock the bicycle 2 . Wherein, before the second processor 142 confirms that the confirmation input is valid, even if the notification signal is confirmed to be valid, the bicycle 2 is still locked by the lock 12 . In this way, the bicycle anti-theft system 1 ensures the security of communication between the portable device 10 and the controller 14 by judging the validity of the encrypted notification signal, and prevents the anti-theft system from being cracked; in addition, the bicycle anti-theft system 1 also responds The confirmation message sent by the controller 14 prevents the bicycle 2 from being unlocked unexpectedly. Therefore, the bicycle anti-theft system 1 can effectively prevent the bicycle 2 from being in the risk of being stolen.

In addition, the first encrypted information and the second encrypted information include at least matching encryption keys, which can be used for encryption and decryption of communications. Therefore, when the controller 14 is connected to the portable device 10 through short-distance communication (for example, based on Bluetooth protocol), the communication between the controller 14 and the portable device 10 can be encrypted. For example, the second processor 142 of the controller 14 encrypts the confirmation message according to the second encryption information and sends the encrypted confirmation message to the portable device 10, and the first processor 102 of the portable device 10 encrypts the confirmation message according to the first encrypted message. information to decrypt the encrypted confirmation message to obtain the confirmation message; similarly, the first processor 102 of the portable device 10 encrypts the confirmation input according to the first encrypted information and transmits the encrypted confirmation input to the controller 14, and controls The second processor 142 of the device 14 decrypts the encrypted confirmation input according to the second encrypted information to obtain the confirmation input. The content of the notification signal may include identification information about the portable device 10 or the controller 14, control authority, limited period and other information.

In addition, in practical applications, the server 4 connected to the telecommunication network 3 may store the first encrypted information and the second encrypted information, so the portable device 10 may not store the first encrypted information originally, but the second encrypted information. A processor 102 receives the first encrypted information from the server 4 through the telecommunications network 3 via the third wireless communication circuit 108 . Similarly, the controller 14 may not store the second encrypted information originally, but the second processor 142 receives the second encrypted information from the server 4 via the fourth wireless communication circuit 148 through the telecommunication network 3 . In other words, the portable device 10 and the controller 14 originally stored the first encrypted information and the second encrypted information respectively, but both the portable device 10 and the controller 14 can update the first encrypted information from the server 4 through the telecommunications network 3 An encrypted message and the second encrypted message; whereby, when the controller 14 updates the second encrypted message but the portable device 10 fails to update the first encrypted message, the updated second encrypted message is in principle identical to the The first encrypted information does not match, and then produces the effect of excluding the portable device 10 from starting the controller 14. In this way, when the portable device 10 and the controller 14 update the encrypted information dynamically and synchronously, other portable devices cannot Knowing the updated first encryption information prevents the controller 14 from starting, which enhances the security of the system.

In addition, in practical applications, if the confirmation message is displayed on the controller 14 and the confirmation input is also input through the controller 14, the portable device 10 can be simplified to only include the first processor 102, the first memory 104. The first wireless communication circuit 106 and the first electric energy storage element 112 make the size of the portable device 10 greatly reduced and still provide the ability to transmit the Encrypted notification signal to controller 14 function. At this time, the first encrypted information can be updated through short-distance communication between the portable device 10 and the server 4 . Similarly, the controller 14 can also omit the fourth wireless communication circuit 148 and instead communicate with the server 4 in a short distance to update the second encrypted information.

In practical applications, the confirmation message includes a confirmation string, and the confirmation string includes at least one character (such as Chinese, Korean, etc.), letters (such as English letters, Latin letters, etc.), numbers or symbols (such as asterisks, question marks, etc. ). As shown in FIG. 2 , the confirmation string is “3847” and is displayed on the display screen 150 a of the second display and input interface 150 . The user uses the button 150b of the second display and input interface 150 to input as the confirmation input. If the confirmation input includes the confirmation string, the second processor 142 will determine that the confirmation input is valid. Similarly, as shown in FIG. 3 , the confirmation string is “3847”, which is displayed on the first display and input interface 110 . The user uses the virtual keyboard of the first display and input interface 110 to input as the confirmation input. The first processor 102 then transmits the confirmation input to the controller 14 via the first wireless communication circuit 106 . If the confirmation input includes the confirmation string, the second processor 142 will determine that the confirmation input is valid.

Please also refer to FIG. 4 , which is a flow chart of the bicycle unlocking method according to the present invention. The bicycle unlocking method is used in the bicycle anti-theft system. For the convenience of description, the bicycle unlocking method will be described based on the bicycle anti-theft system 1 mentioned above as an example. For the relevant description of the bicycle anti-theft system 1, please refer to the foregoing. The bicycle unlocking method includes that after the first processor 102 and the second processor 142 are connected via the first wireless communication circuit 106 and the second wireless communication circuit 146 for short-distance communication (for example, through wifi, bluetooth and other communication protocols for short-distance communication connection) ), the first processor 102 encrypts the notification signal according to the first encryption information and transmits the encrypted notification signal to the controller 14 via the first wireless communication circuit 106, as shown in step S110; The communication circuit 146 receives the encrypted notification signal, as shown in step S120; the second processor 142 judges whether the encrypted notification signal is valid according to the second encrypted information, and if valid, the second processor 142 generates a confirmation message, as shown in step S130; the second processor 142 displays the confirmation message through the second display and input interface 150 or transmits the confirmation message to the portable device 10 through the second wireless communication circuit 146, as shown in step S140; When the second processor 142 receives the confirmation input input by the user according to the confirmation message through the second display and input interface 150 or receives the confirmation input from the portable device 10 through the second wireless communication circuit 146, the second The second processor 142 judges whether the confirmation input is valid, and if the confirmation input is valid, the second processor 142 controls the lock 12 to unlock the bicycle 2, as shown in step S150. In this way, the bicycle unlocking method ensures the security of communication between the portable device 10 and the controller 14 by judging the validity of the encrypted notification signal, preventing the anti-theft system from being cracked; in addition, the bicycle unlocking method also responds to The confirmation message sent by the controller 14 prevents the bicycle 2 from being unlocked unexpectedly. Therefore, the bicycle unlocking method can effectively prevent the bicycle 2 from being in the risk of being stolen.

Please refer to FIG. 5A and FIG. 5B , which are flowcharts of the bicycle unlocking method according to an embodiment. For the convenience of description, the bicycle unlocking method will be described based on the bicycle anti-theft system 1 mentioned above as an example. For the relevant description of the bicycle anti-theft system 1, please refer to the foregoing. The bicycle unlocking method includes that the first processor 102 of the portable device 10 receives and updates the first encrypted information from the server 4 via the third wireless communication circuit 108 through the telecommunications network 3, and the second processor 142 of the controller 14 via The fourth wireless communication circuit 148 receives and updates the second encrypted information from the server 4 through the telecommunications network 3, as shown in step S200; wherein if the portable device 10 does not initially have stored first encrypted information, the portable device 10 In this step, the device 10 only downloads and stores the first encrypted information. According to the method for unlocking the bicycle, it is judged whether the first processor 102 and the second processor 142 are connected via the first wireless communication circuit 106 and the second wireless communication circuit 146 for short-distance communication (such as short-distance communication through wifi, bluetooth, etc.) connection), as shown in step S210; if not, then continue to wait for the communication connection between the first processor 102 and the second processor 142, that is, return to step S210; if so, the first processor 102 encrypts the notification according to the first encrypted information signal and transmit the encrypted notification signal to the controller 14 via the first wireless communication circuit 106, as shown in step S212. Wherein, steps S210 and S212 correspond to the aforementioned step S110.

Next, according to the bicycle unlocking method, the second processor 142 receives the encrypted notification signal via the second wireless communication circuit 146, as shown in step S220; the second processor 142 judges the encrypted notification signal according to the second encrypted information Whether it is valid, as shown in step S230. In practical applications, whether the encrypted notification signal is valid can be determined by whether the encrypted notification signal can be correctly decrypted, or by judging whether the content of the decrypted notification signal is valid. In the former, when the encrypted notification signal is correctly decrypted, the decrypted notification signal has meaningful content and format, and it can be confirmed that the encrypted notification signal is valid. In the latter case, even if the decrypted notification signal has meaningful content and format, but the content cannot make the portable device 10 have legal authority to control the controller 14, the encrypted notification signal is still confirmed to be invalid. If the second processor 142 determines that the encrypted notification signal is invalid, the process returns to step S210 to wait for the authorized portable device to communicate with the controller 14 . If the second processor 142 determines that the encrypted notification signal is valid, the second processor 142 generates a confirmation message, as shown in step S232. Wherein, step S220 corresponds to the aforementioned step S120, and steps S230 and S232 correspond to the aforementioned step S130.

In this embodiment, according to the bicycle unlocking method, the second processor 142 displays the confirmation message through the second display and input interface 150, as shown in step S240. At this time, the user can see the confirmation message (as shown in FIG. 2 ) through the second display and input interface 150 , and can input through the second display and input interface 150 according to the confirmation message. When the user inputs a confirmation input through the second display and input interface 150 according to the confirmation message, the second processor 142 can receive the confirmation input through the second display and input interface 150, as shown in step S250; then, the second The second processor 142 determines whether the confirmation input is valid, as shown in step S252. In practical applications, the confirmation message may include a confirmation string, and the confirmation string includes at least one character, letter, number or symbol, so in step S240, the second processor 142 displays the confirmation string through the second display and input interface 150 A confirmation string, and in step S150, if the confirmation input includes the confirmation string, the second processor 142 determines that the confirmation input is valid. As shown in FIG. 2 , the confirmation message is "Please input: 3847", so when the confirmation input is "3847", the second processor 142 will determine that the confirmation input is valid. Therefore, when the user inputs other numbers, the second processor 142 will judge that the confirmation input is invalid; at this time, the process can return to before step S250, waiting to receive the user's new confirmation input, to execute again Steps S250, S252. In practical applications, the process can also return to step S210 after the user makes one or more wrong inputs to re-execute steps such as communication access, signal notification, message confirmation, and input confirmation. According to the bicycle unlocking method, if the second processor 142 determines that the confirmation input is valid, the second processor 142 controls the lock 12 to unlock the bicycle 2, as shown in step S254. Wherein, step S240 corresponds to the aforementioned step S140, and steps S250, S252, and S254 correspond to the aforementioned step S150.

Please refer to FIG. 6A and FIG. 6B , which are flowcharts of the bicycle unlocking method according to another embodiment. For the convenience of description, the bicycle unlocking method will be described based on the bicycle anti-theft system 1 mentioned above as an example. For the relevant description of the bicycle anti-theft system 1, please refer to the foregoing. In this embodiment, the bicycle unlocking method is substantially the same as the bicycle unlocking method shown in FIG. 5A and FIG. 5B, so for other descriptions of the bicycle unlocking method shown in FIG. 6A and FIG. Relevant descriptions of the bicycle unlocking method shown in 5B will not be repeated here. The main difference between the bicycle unlocking method of this embodiment and the bicycle unlocking method shown in FIGS. 5A and 5B is that the confirmation message is input by the portable device 10 , and the user directly uses the portable device 10 to input the confirmation input. Further, as shown in FIG. 6A and FIG. 6B, according to step S232, after the second processor 142 generates the confirmation message, the second processor 142 sends the confirmation message to the portable device 10 via the second wireless communication circuit 146 , as shown in step S340; the first processor 102 receives the confirmation message through the first wireless communication circuit 106 and displays the confirmation message through the first display and input interface 110, as shown in step S342.
