Detailed implementation manners

[0051] To more clearly understand the purpose, technical solution and advantages of the present application, the present application will be described and explained below with reference to the drawings and embodiments.

[0052] Unless otherwise defined, the technical terms or scientific terms involved in the present application shall have the general meaning understood by those with ordinary skills in the technical field to which the present application belongs. In the present application, words such as "a", "one", "a kind of", "the", "these" and the like do not indicate a limitation in quantity, and they can be singular or plural. The terms "including", "comprising", "having" and any variants thereof involved in the present application are intended to cover non-exclusive inclusion; for example, a process, method, system, product or device including a series of steps or modules (units) is not limited to the listed steps or modules (units), but may include unlisted steps or modules (units), or may include other steps or modules (units) inherent in these processes, methods, products or devices. The terms "connected", "coupled" and the like involved in the present application do not limit to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The term "plurality" involved in the present application refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" may represent: A exists alone, A and B exist simultaneously, and B exists alone. Usually, the character " / " indicates that the objects before and after are in an "or" relationship. The terms "first", "second", "third" and the like involved in the present application are only used to distinguish similar objects and do not represent a specific order for the objects.

[0053] The embodiments of the present application are applicable to unlocking scenarios where users authenticate their identities through palm vein recognition, such as unlocking cabinet locks, vehicle locks, door locks, etc. The user raises their hand and pauses for a period of time for the smart lock to recognize the user's identity. After successful recognition, the smart lock detects the dirt and bacteria information on the user's hand to obtain a detection result. The detection result includes the bacteria content and dirt content on the user's palm. When the detection result meets the preset conditions, the cleaning module deployed in the smart lock is controlled to automatically clean the user's hand. After the cleaning is completed, the user pulls the handle. When there are bacteria and dirt on the user's hand, the user does not touch the handle. After the user's hand is cleaned, the user then touches the handle. Therefore, the embodiments of the present application avoid cross-infection caused by bacteria and dirt on the user's hand remaining on the handle and also avoid pollution of the environment (such as indoor environment, objects in the cabinet, inside the vehicle, etc.) by bacteria and dirt on the user's hand after unlocking. By combining palm vein recognition, bacteria and dirt detection, and automatic hand disinfection, the problem of cross-infection caused by bacteria and dirt on the user's hand is solved more thoroughly.

[0054] The method provided by the embodiments of the present application can be applied to smart locks, including smart cabinet locks, smart vehicle locks, smart door locks, etc. It can be understood that a smart lock is a lock that replaces a traditional mechanical lock through electronic technology and intelligent control methods. In addition to palm vein recognition authentication, a smart lock can also combine technologies such as fingerprint recognition, face recognition, and voiceprint recognition to achieve user identity authentication. During the identity authentication process, the bacteria and dirt on the user's hand are detected, and whether the user's palm is clean and healthy is determined by combining the bacteria content and dirt content to reduce misjudgment. As an example, Figure 1 shows a schematic diagram of the hardware structure of a smart lock provided by the embodiments of the present application, as Figure 1 shown, the smart lock includes: an induction module 101, a main control module 102, a palm vein recognition module 103, a bacteria detection module 104, a camera module 105, a cleaning module 106, and other modules 107. Each hardware module will be described below.

[0055] The induction module 101 is used to sense whether an object enters the recognition range. If so, the induction module 101 sends a first instruction to the main control module 102. The induction module 101 may include, but is not limited to, a high-definition cat's eye camera, a radar induction module, a biometric sensor, and an environmental monitoring sensor, etc. In addition, the induction module 101 can be installed on the front panel of the smart lock (i.e., the side facing outside the lock) to capture and record outdoor information (or information outside the vehicle, outside the cabinet, etc.) in real time, such as personnel entry and exit, activity trajectories, etc.

[0056] The main control module 102 has three main functions. The first function is control and coordination, that is, it receives and processes input signals from various modules, such as user operation instructions transmitted by sensors, password keyboards, card readers, mobile phone applications (APPs), etc., and then performs corresponding processing and operations according to the preset program to coordinate the work among the various components of the intelligent lock. The second function is power management, specifically to control the power on and off of each module. For example, in response to the first instruction, it controls the palm vein recognition module 103 and the camera module 105 to power on, so that the palm vein recognition module 103 and the camera module 105 are started synchronously. The third function of the main control module 102 is security and protection, identity authentication, encryption and decryption, data storage, local communication, and so on.

[0057] The palm vein recognition module 103 is controlled by the main control module 102. By performing feature extraction processing on the palm image collected in the recognition area, the palm vein features of the user are obtained, and based on the palm vein features, it identifies whether the user's identity matches. In the case of a match, it controls the intelligent lock to open.

[0058] The bacteria detection module 104 is controlled by the main control module 102 and is used to detect the bacteria content on the user's palm. The bacteria detection module 104 includes a light source emitter and an image analysis and processing unit. The light source emitter is used to emit light to the palm area of the user, and this light causes the bacteria in the palm area to emit fluorescence. The image analysis and processing unit collects the fluorescence and forms an image, and identifies the bacteria in the fluorescence image to obtain the bacteria content in the fluorescence image.

[0059] The camera module 105 is controlled by the main control module 102 and can scan the palm for image recognition processing to detect the dirt content on the user's palm. As an example, the camera module 105 includes a cat's eye and an image processing unit.

[0060] The cleaning module 106 can clean the user's hand, and its cleaning methods include but are not limited to: spraying disinfectant, disinfection foam, hand sanitizer, irradiating ultraviolet light, etc. It should be noted that the cleaning module 106 automatically turns on when it detects that the bacteria content and dirt content on the user's hand meet the preset conditions, without the need for manual operation by the user. The cleaning process is completely automated, providing a better intelligent experience.

[0061] The other modules 107 include but are not limited to: WIFI module, Bluetooth module, voice module, fingerprint recognition module, etc. For these modules, reference can be made to the introduction of related technologies, and no redundant description will be given here.

[0062] Those of ordinary skill in the art can understand that Figure 1 The structure shown is only schematic and does not limit the structure of the intelligent lock. For example, the intelligent lock may also include more or fewer components than Figure 1 shown, or have a structure different from Figure 1The different configurations shown. By way of example and not limitation, a proximity sensing module can be added to the door body (or cabinet body), and the proximity sensing module is configured to generate a wake-up signal when a proximity object enters the sensing area, so as to control the main control module to turn on. Alternatively, other modules 107 can be reduced in the smart lock.

[0063] Taking the smart lock as an example of a smart door lock, a hand cleaning method provided by an embodiment of the present application will be described in combination with the smart door lock including the above-mentioned various modules. Figure 2 The flowchart of a hand cleaning method provided by an embodiment of the present application is shown, as Figure 2 shown, the method includes steps S201 to S204.

[0064] Step S201, when the sensing module detects that the user enters the recognition range, control the palm vein recognition module and the camera module deployed on the smart door lock to start.

[0065] The sensing module 101 can be installed on the door body or on the wall outside the door. The installation position of the sensing module 101 is based on being able to detect the entry and exit of personnel within the recognition range. The sensing module 101 can include but is not limited to a high-definition cat's eye camera, a radar sensing module, a biometric sensor, an environmental monitoring sensor, etc.

[0066] In some embodiments, the sensing module 101 includes a radar sensing module, and step S201 further includes: when the radar sensing module detects that the user enters the recognition range, send a first instruction to the main control module 102 of the smart door lock, so that the main control module 102 controls the palm vein recognition module 103 and the camera module 105 deployed on the smart door lock to turn on.

[0067] In this embodiment, the sensing module 101 is a radar sensing module. When the user (or object) approaches the smart door lock and stays for a relative time, the radar sensing module is awakened and sends a first instruction to the main control module. The first instruction is used to indicate that the user is detected to enter the recognition range.

[0068] The palm vein recognition module 103 and the camera module 105 are respectively electrically connected to the main control module. In the case of detecting the user, the palm vein recognition module 103 and the camera module 105 are in a closed state, thereby saving power. When the main control module receives the first instruction, the main control module powers on the palm vein recognition module 103 and the camera module 105 respectively, so that the palm vein recognition module 103 and the camera module 105 are controlled to turn on.

[0069] In some of these embodiments, the palm vein recognition module 103 and the camera module 105 are started simultaneously, making the processes of bacterial detection and dirt detection of the hand more synchronous. After the palm vein recognition module 103 and the camera module 105 are controlled to be turned on, the recognition of the user's identity and the recognition of dirt on the user's palm can be carried out synchronously. That is, after step S201, step S202 and step S203 can be executed respectively.

[0070] In other embodiments, after the camera module 105 is started, the dirt on the palm is not immediately recognized. Instead, after the palm vein recognition module 103 passes the user's identity verification, the dirt on the user's palm is recognized, which can reduce unnecessary image processing steps. That is to say, step S203 can be executed when the user's identity recognition is passed, so as to only recognize the dirt on the palm of the user whose identity verification is passed, in order to reduce power consumption.

[0071] Step S202: Identify the user's identity based on the user's palm vein characteristics. When the identification is passed, start the bacterial detection module to detect the bacterial content of the user's palm to obtain the bacterial content.

[0072] In this step, palm vein remote recognition is adopted, that is, the user raises the hand and stays at the detection and recognition window, and the palm vein recognition module 103 in the smart door lock recognizes the palm in the area of the detection and recognition window. When the recognition is successful, the bacterial detection module 104 will be started to detect the bacterial content of the user's palm when the user raises the hand and stays. Among them, the detection and recognition window is the area in front of the middle of the smart door lock.

[0073] In some of these embodiments, when the user raises the hand, the palm is opened and forms a roughly parallel angle with the smart door lock, so that the palm vein recognition module 103 can obtain the user's palm vein characteristics. In other embodiments, the user's hand is in a posture of loosely holding the door handle, with the palm facing the door handle, and the palm vein recognition module 103 collects a picture of the user's palm (local palm vein image) and extracts the user's palm vein characteristics from the picture of the palm. In the above two implementation methods, the user's palm does not touch the handle, so the bacteria and dirt on the user's hand will not be transferred to the handle. Therefore, only the user's hand needs to be cleaned, and there is no need to clean the handle. One-time cleaning can avoid the contamination of the handle by the bacteria and dirt on the user's hand and also prevent the user from bringing bacteria and dirt back into the room.

[0074] In some of these embodiments, as Figure 3 shown, step S202 further includes step S301 to step S302.

[0075] Step S301: Identify the user's palm vein characteristics through the palm vein recognition module and match the palm vein with the pre-recorded template characteristics.

[0076] Among them, the template feature can be set by the user on the application of the mobile terminal, and the palm vein image of the user is input as the template feature of the user.

[0077] In this step, the palm vein recognition module 103 includes an optical acquisition system, an image processing chip, and a feature extraction and storage module. The optical acquisition system emits infrared light to irradiate the palm veins. The image processing chip utilizes the absorption characteristic of hemoglobin for near-infrared rays to obtain the image of the palm vein blood vessels. The feature extraction and storage module matches the extracted palm vein features with the template features stored in the system to perform personal identity identification. Specifically, the texture of each person's palm vein blood vessels is unique, which makes the palm vein recognition technology have extremely high recognition accuracy and anti-counterfeiting performance; only need to place the palm above the recognition device, and the identity verification can be completed without contact, the operation is simple and fast, and the hygiene is good, reducing the risk of cross-infection, meeting the modern hygiene requirements; at the same time, the palm vein is hidden inside the palm and is not easy to be forged or copied. Compared with other biometric technologies, such as fingerprint recognition and face recognition, it has higher security and can effectively prevent identity theft.

[0078] Step S302, in the case of successful matching, start the bacteria detection module to detect the bacteria content of the user's palm to obtain the bacteria content.

[0079] The bacteria detection module 104 includes a light source emitter and an image processing and analysis unit, and mainly uses the optical principle to detect bacteria. Specifically, the light source emitter emits a specific light source onto the user's palm to make the bacteria on the palm emit specific fluorescence. The image processing and analysis unit calculates the bacteria content of the palm through an image recognition algorithm.

[0080] In some embodiments, as Figure 4 shown, step S302 includes steps S401 to S403.

[0081] Step S401, start the light source emitter to emit light to the palm area of the user.

[0082] Step S402, process the fluorescence data returned from the palm area through the image processing and analysis unit to obtain a fluorescence image.

[0083] Step S403, identify the bacteria in the fluorescence image to obtain the bacteria content in the fluorescence image.

[0084] In this embodiment, the fluorescence emitted by the bacteria is imaged after being processed by the image processing and analysis unit to obtain a fluorescence image. The image processing and analysis unit identifies the bacteria in the fluorescence image to obtain the bacteria content. Among them, the bacteria content can be the area ratio of the fluorescence region in the fluorescence image to the palm region. The larger the area ratio, the higher the bacteria content, indicating that the hand is dirtier; the smaller the area ratio, the lower the bacteria content, indicating that the hand is cleaner.

[0085] Through the above step S202, the embodiment of the present application identifies the user's identity. If the identification is passed, the bacteria content of the user's hand is detected, so as to determine whether the bacteria content of the user's hand exceeds the standard in the subsequent steps.

[0086] Step S203: Obtain the palm image of the user through the camera module, and identify the dirt in the palm image to obtain the dirt content in the palm image.

[0087] The camera module 105 includes a cat's eye and an image processing unit. The camera module 105 can scan the palm for image recognition processing, capture and judge whether there is dirt on the palm, so as to determine whether the dirt content of the user's hand exceeds the standard in the subsequent steps.

[0088] Step S204: Generate a bacteria and dirt detection result by combining the bacteria content and the dirt content. If the bacteria and dirt detection result meets the preset conditions, control the cleaning module to clean the user's hand.

[0089] In this step, the preset conditions are used to determine whether the bacteria and dirt on the user's hand exceed the standard. If the bacteria and dirt detection result meets the preset conditions, it means that the bacteria and dirt on the hand exceed the standard, otherwise it means that the bacteria and dirt on the hand do not exceed the standard. When the bacteria and dirt exceed the standard, clean the user's hand.

[0090] It is worth mentioning that in this step, it is considered that it is easy to cause misjudgment to determine whether the user's hand is clean only by the bacteria content or only by the dirt content. Therefore, the bacteria detection module 104 and the camera module 105 are used in combination, and the clean and healthy condition of the user's palm is determined based on the results of the two, reducing misjudgment and improving the detection accuracy.

[0091] Specifically, as Figure 5 shown, step S204 includes: step S501 to step S502.

[0092] Step S501: If the bacteria content is greater than the first threshold or the dirt content is greater than the second threshold, control the cleaning module to clean the user's hand.

[0093] Step S502: If the bacteria content is greater than the third threshold and the dirt content is greater than the fourth threshold, control the cleaning module to clean the user's hands; wherein the first threshold is greater than the third threshold, and the second threshold is greater than the fourth threshold.

[0094] It can be seen from step S502 that when it is detected that the bacteria content and the dirt content simultaneously meet the threshold, the user's hands are cleaned; otherwise, it is recorded that the user's palms are clean and healthy.

[0095] When the bacteria content is greater than the first threshold or the dirt content is greater than the second threshold, the user's hands only need to be cleaned if either condition is met.

[0096] For example, the first threshold and the second threshold may be 0.7, and the third threshold and the fourth threshold may be set to 0.3. When any value of the bacteria content and the dirt content is greater than 0.7, the user's hands are cleaned, but if the bacteria content or the dirt content is between 0.3 and 0.7, the user's hands are cleaned only when both the bacteria content and the dirt content are greater than 0.3. This method of setting two thresholds for the bacteria content and the dirt content respectively reduces the misjudgment of the cleanliness and health of the user's palms and improves the detection accuracy.

[0097] In this embodiment, the cleaning method for the user's hands includes but is not limited to: a solution storage bottle or an ultraviolet lamp is built into the smart door lock to control the solution storage bottle to spray disinfectant or disinfectant foam, or to control the ultraviolet lamp to irradiate ultraviolet rays.

[0098] As an example, the cleaning module 106 includes a driving unit, a motor, and a solution storage bottle. Controlling the cleaning module 106 to clean the user's hands includes: sending a second instruction to the driving unit, the second instruction is used for the driving unit to drive the motor to rotate to press the button of the solution storage bottle, so that the solution storage bottle releases the cleaning disinfectant to the user's hands.

[0099] In this step, the driving unit (ie, the motor) rotates and drives the push rod, so that the push rod presses the button of the solution storage bottle, causing the solution storage bottle to spray out the corresponding liquid (ie, the cleaning disinfectant).

[0100] Through the above steps S201 to S204, the embodiment of the present application provides a hand cleaning method for an intelligent door lock, which is applied to the intelligent door lock. The intelligent door lock includes an induction module 101, a palm vein recognition module 103, a camera module 105, and a bacteria detection module 104. When the induction module 101 detects that a user enters the recognition range, it controls the palm vein recognition module 103 and the camera module 105 deployed on the intelligent door lock to start. The identity of the user is recognized according to the palm vein characteristics of the user. In the case of successful recognition, the bacteria detection module 104 is started to detect the bacteria content on the user's palm to obtain the bacteria content. The palm image of the user is obtained through the camera module 105, and the dirt in the palm image is recognized to obtain the dirt content in the palm image. The bacteria dirt detection result is generated by combining the bacteria content and the dirt content. If the bacteria dirt detection result meets the preset conditions, the cleaning module 106 is controlled to clean the user's hand. In this embodiment, by automatically identifying the hand hygiene status and combining identity recognition with hand cleaning without interfering with user authentication, the active operation steps of the user are reduced, so the convenience and comfort of user use are improved. The user only needs to enter the recognition range, and the intelligent door lock will automatically detect and start the cleaning program according to the situation, which not only saves time but also avoids the situation of polluting the handle and indoor hygiene due to human negligence and failure to clean the hands in time.
