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 implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.
It should be noted that all actions of acquiring signals, information or data in the present application are performed under the premise of complying with the corresponding data protection regulation policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
Fig. 1 is a flowchart illustrating an unlocking method according to an exemplary embodiment, which is used in an intelligent door lock, as shown in fig. 1, and includes the following steps.
In step S11, in response to the unlock request, a virtual operation interface is generated by projection in a preset area.
In step S12, by detecting the position where the blocking signal is generated on the virtual operation interface, the corresponding decryption information is determined.
In step S13, in case that the decryption information matches the preset decryption information, controlling the smart door lock to perform an unlocking operation.
For example, in step S11, it should be noted that the unlocking method disclosed in this embodiment is mainly applied to an intelligent door lock, and the mechanical device of the intelligent door lock is controlled to perform an unlocking operation or maintain a locked state according to the verification result of the unlocking method. The intelligent door lock normally keeps a locked state before receiving an unlocking request sent by a user. And after an unlocking request sent by a user is received, a virtual operation interface can be generated in a preset area of the intelligent door lock through projection.
For example, a button may be set at a corresponding position of the intelligent door lock, and when a user has an unlocking demand, an unlocking request is sent to the intelligent door lock by pressing the corresponding control button, so that the intelligent door lock generates a virtual operation interface in a preset area; or, an unlocking request can be sent to the intelligent door lock based on the terminal equipment by establishing wireless communication between the terminal equipment and the intelligent door lock; or, the NFC control module may be further installed on the smart door lock, and the user wakes up the smart door lock based on the NFC card reading chip and sends an unlocking request to the smart door lock, which is not limited in this embodiment.
After the intelligent door lock receives an unlocking request sent by a user, a virtual operation interface can be projected in a preset area through a projection device in the intelligent door lock. For example, the preset area may be a wall surface opposite to the projection device, and the virtual operation interface is generated on the corresponding wall surface through projection; or, a projection baffle can be set at a preset position of the intelligent door lock, and the virtual operation interface is projected onto the baffle. It can be understood that the virtual operation interface generated by the projection apparatus is used for enabling a user to input an unlocking password on the virtual operation interface, and the virtual operation interface may be a virtual full keyboard, a virtual 9-grid keyboard, or a virtual drawing board, and the corresponding decryption information is generated based on a sliding track or a clicking operation of the user on the virtual operation interface.
It should be noted that, in order to facilitate subsequent detection of decryption information, the projection apparatus in this embodiment may project a virtual operation interface formed by infrared lasers to a preset area of the smart door lock through the infrared filter and the infrared lasers, so as to determine a sliding track or a click position of a user on the virtual operation interface by detecting an infrared light signal subsequently.
Optionally, the step S11 may further include:
in response to the unlock request, an air screen is generated within a preset area by an air screen device.
And projecting the preset light beam onto the air screen through the projection device to generate a virtual operation interface.
It can be understood that, in this embodiment, the intelligent door lock includes an air screen device, the air screen device can generate an air screen at a preset position of the intelligent door lock through fine water mist, after the intelligent door lock receives an unlocking request sent by a user, a preset light beam can be projected onto the air screen through the projection device, and a virtual operation interface is generated on the air screen. The preset light beam of the projection device needs to be projected into the screen to form an image, and a virtual operation interface is generated. In this embodiment, the air screen device can utilize the sprinkler to spray the higher one deck water smoke of concentration to in the air to form the translucent air screen of one deck in the preset region of intelligent lock, when predetermineeing the light beam projection to the air screen, because the opacity of intensive hydrone, thereby generate virtual operation interface on the air screen.
Optionally, before the step S11, the unlocking method further includes:
and detecting a Bluetooth connection request sent by the terminal equipment.
And under the condition that the terminal equipment is determined to be the terminal equipment bound with the intelligent door lock, determining that the Bluetooth connection is successful.
And generating an unlocking request in response to the signal that the Bluetooth connection is successful.
It can be understood that, after the intelligent door lock receives the unlocking request, the virtual operation interface needs to be generated by projection in the preset area of the intelligent door lock. The projection process of intelligence lock needs to consume certain electric quantity, for avoiding the false triggering of intelligence lock projection process, needs carry out preliminary verification to the start-up process of intelligence lock. In the embodiment, the Bluetooth module is arranged in the intelligent door lock, the Bluetooth communication signal is detected in real time, communication connection between the intelligent door lock and the terminal equipment is established, and the unlocking request is generated after the terminal equipment is successfully connected with the intelligent door lock through Bluetooth. Normally, the communication connection of the bluetooth module needs to be within a certain distance range, for example, the communication distance of the bluetooth module may be 10-20 meters, and the communication connection of the bluetooth module can be triggered only when the distance between the terminal device and the intelligent door lock is within the communication distance of the bluetooth module of the intelligent door lock. Therefore, after the Bluetooth connection request sent by the terminal device is detected, the terminal device is closer to the door lock, the Bluetooth connection request is verified at the moment, whether the terminal device is matched with the intelligent door lock or not is determined, and under the condition that the terminal device is successfully matched with the intelligent door lock, the terminal device is determined to be legal equipment, so that the user of the terminal device is determined to be a legal user with unlocking authority, the verification is passed, and then after the Bluetooth connection is successful, an unlocking request of the intelligent door lock is generated, so that the intelligent door lock generates a corresponding virtual operation interface according to the unlocking request. In the embodiment, the Bluetooth module is used for verifying whether a user holding the terminal equipment is a legal user, and a virtual operation interface is opened to verify decryption information under the condition that the Bluetooth of the terminal equipment and the Bluetooth module of the intelligent door lock can be successfully paired. On the premise of ensuring unlocking safety, the convenience of the intelligent door lock is improved.
Optionally, before the step S11, the unlocking method may further include:
the distance between the user and the intelligent door lock is detected through the distance sensor.
And generating an unlocking request under the condition that the distance is smaller than a preset threshold value.
It can be understood that when the user has an unlocking intention, the user needs to approach the intelligent door lock to a certain distance to operate the virtual operation interface to complete the operation of inputting the decryption information. Therefore, in this embodiment, the distance between the user and the smart door lock is detected by installing the distance sensor in the smart door lock. For example, the distance sensor may be an infrared sensor, and emit an infrared light through the infrared sensor to detect a horizontal distance between the user and the smart door lock, and when the horizontal distance is smaller than a preset threshold, it indicates that the user has reached an unlocking area of the smart door lock and has an unlocking intention, so as to generate an unlocking instruction. For example, in order to avoid that a passerby mistakenly triggers a virtual operation interface of the intelligent door lock due to an overlarge distance, the preset threshold value can be set to be 30cm, and when the horizontal distance between a user and the infrared sensor is smaller than 30cm, a corresponding unlocking request is generated; optionally, to ensure the accuracy of the sensing device, the preset threshold may also be set to 10cm, and a user with an unlocking intention may manually shield the distance sensor to trigger the virtual operation interface of the smart door lock.
For example, in step S12, the virtual operation interface is a light-sensing virtual operation interface generated in a preset area based on the projected light of the projection device, and when a blocking object appears between the projection surface and the projection device, a shadow will be generated at the corresponding position of the projection surface, so that the corresponding projected light cannot be transmitted to the projection surface. In this embodiment, the projection device is an infrared sensing device, and when a user performs operations such as password input on the projection surface through a barrier such as a finger, the projection device generates a blocking signal at a corresponding position, and generates corresponding decryption information by analyzing a position where the blocking signal is generated and combining a virtual operation interface. In an example, the virtual operation interface is set to be a 9-grid numeric keypad, after the intelligent door lock generates the virtual operation interface in the preset area, the user performs password input operation based on the virtual operation interface on the projection surface, when the user performs key operation on the virtual operation interface by fingers, shadows in a certain area are generated on the projection surface due to the light impermeability of the fingers of the user, blocking signals for blocking the light beam propagation of the projection device are generated according to the shadows, and corresponding decryption information is generated by analyzing the positions of the blocking signals generated on the virtual 9-grid keypad.
Optionally, the smart door lock includes an infrared camera device, the virtual operation interface is a virtual keyboard, and the step S12 may include:
and detecting the position of the blocking signal generated on the virtual keyboard through an infrared camera device.
And analyzing the position based on the virtual keyboard to generate decryption information.
It can be understood that the virtual operation interface generated on the projection plane in this embodiment is a virtual keyboard, and the virtual keyboard may be a full keyboard or a 9-grid keyboard. The detection device is used for detecting the projection signal on the virtual keyboard, and when the shadow area for blocking the projection light beam is generated at the corresponding position of the virtual keyboard, the intelligent door lock can generate a blocking signal based on the blocked projection light beam. By analyzing the blocking signal, the position of the user's finger on the virtual keyboard can be determined, thereby generating decryption information. When an obstacle appears between the projection surface and the projection device, the projection device generates a blocking signal according to the propagation distance of the projection beam, determines the position of the blocking signal generated on the corresponding projection surface through analysis of the propagation distance, and determines corresponding decryption information through analysis of the position.
Optionally, the intelligent door lock includes an infrared camera device, and the step S12 may further include:
a plurality of positions where the blocking signals are generated on the virtual operation interface are detected by an infrared camera device.
And determining a moving track on the virtual operation interface according to the plurality of positions.
And analyzing the moving track to generate decryption information.
It can be understood that an infrared camera device is provided in the smart door lock for detecting a position where the blocking preset light beam is projected onto the air screen and generating a blocking signal based on the position. In this embodiment, the infrared light projected onto the air screen is detected by the infrared camera device, and when the user performs a key operation on the air screen, the light-tight property of the finger of the user may prevent the preset light beam from being projected onto the air screen, and a shadow region may be generated on the air screen. The infrared camera device generates a corresponding blocking signal through the shadow area, determines a moving track of the blocking signal on the virtual operation interface based on the virtual operation interface, and analyzes the moving track to generate corresponding decryption information.
For example, in step S13, it may be understood that preset decryption information is set in advance in the smart door lock, and whether the password input by the user is correct is determined by comparing the decryption information input by the user based on the virtual operation interface with the preset decryption information. And controlling the intelligent door lock to execute unlocking operation under the condition that the decryption information is the same as the preset decryption information.
Optionally, the unlocking method may further include:
and sending out a prompt audio to prompt the user to re-input the password under the condition that the decryption information is not matched with the preset unlocking information.
It can be understood that the smart door lock in the present embodiment includes a language prompt module for issuing a prompt language. After the decryption information is input into the intelligent door lock through the steps, whether the decryption information is matched with the preset decryption information needs to be determined, and unlocking operation is executed when the decryption information is matched with the preset decryption information; under the condition that the decryption information is not matched with the preset decryption information, a prompt audio is sent out through a voice prompt module of the intelligent door lock to remind a user that the password is wrong and needs to be input again.
Through the implementation mode, in response to an unlocking request, a virtual operation interface is generated in a preset area through projection, corresponding decryption information is determined through detecting the position of a blocking signal generated on the virtual operation interface, and the intelligent door lock is controlled to execute unlocking operation under the condition that the decryption information is matched with the preset decryption information. The method comprises the steps of generating a virtual operation interface through projection in a preset area, detecting the position of a blocking signal generated when a user operates on the virtual operation interface, determining decryption information input by the user, and controlling the intelligent door lock to execute unlocking operation under the condition that the decryption information is matched with the preset decryption information. The technical problem that the biological characteristics are easy to leak due to the fact that the biological characteristics need to be input in advance in the existing intelligent door lock is solved. Through carrying out no trace operation on virtual operation interface, avoided the password to reveal, promoted the security of intelligent lock.
