Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smart home, in particular to a smart door lock control method and device and a smart door lock. BACKGROUND

[0002] Traditional smart door locks mostly rely on single or simple combination of biometric features such as password, fingerprint, face recognition or voiceprint recognition for identity verification. Among them, voiceprint recognition is considered as a relatively safe and user-friendly unlocking method due to its non-contact and potential long-distance recognition capability. However, the existing voiceprint recognition technology has the following shortcomings:

[0003] 1) Security problem: single voiceprint recognition is vulnerable to recording attacks or voice imitation, reducing the security of the system. For example, an attacker can pre-record the voiceprint of the target user and play it back to unlock the door illegally.

[0004] 2) Environmental adaptability: in noisy environments, insufficient light scenes or cases where the user's voice energy is small, the accuracy of voiceprint recognition will decrease significantly, affecting user experience.

[0005] 3) Lack of physiological state detection: existing smart door locks cannot determine the physiological state of the user when performing voiceprint recognition, such as drunkenness, coercion or illness, which may lead to the unlocking of the door in inappropriate situations, increasing the security risk.

[0006] 4) Dependence on network synchronization: some smart door locks need to rely on stable network connection for voiceprint matching, and once the network is interrupted or delayed, it will affect the response speed and reliability of the door lock.

[0007] 5) User experience: complicated operation steps, the user needs to repeat multiple times when performing voiceprint recognition, especially in the case of initial setup or high environmental noise, which reduces the convenience of the door lock and user acceptance.

[0008] In view of the above problems, no effective solution has been proposed so far. SUMMARY

[0049] Embodiment 1

[0050] According to the embodiments of the present application, a method embodiment of an intelligent door lock control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown.

[0051] Figure 2 is a flowchart of an intelligent door lock control method according to the embodiments of the present application, as Figure 2 shown, the intelligent door lock control method includes the following steps:

[0052] In step S202, when detecting an unlocking trigger instruction, an unlocking instruction word is generated, wherein the unlocking instruction word is a word randomly generated and used to assist unlocking.

[0053] ​In this embodiment, the smart door lock system is activated upon detecting a user's action to trigger the unlocking. This usually includes the user touching the inductive area of the door lock, voice wake-up, mobile device remote triggering, etc. The detection of the trigger instruction is the starting point of the entire control flow, ensuring that the system is started when needed, improving the user experience while maintaining the security and response efficiency of the system.

[0054] When the unlocking trigger instruction is detected, the smart door lock system dynamically generates a word containing a specific voice instruction through the quantum random number generator. For example, the system may generate the following instruction: "Please say the current temperature is {random number} degrees Celsius." The {random number} is provided by the quantum random number generator, ensuring that each generated instruction is unique and difficult to predict and copy, thereby enhancing the security of voiceprint recognition.

[0055] Figure 3 is a schematic diagram of a smart door lock according to an embodiment of the present application, as Figure 3 shown, which includes a main controller, a quantum random number generator, a millimeter wave radar, a metabolic sensor, a camera, a microphone, a speaker, a screen display, and a fingerprint module / password keyboard, which cooperates to realize the security barrier unlocking function of the door lock. The main controller sends control instructions through user triggers, and the instructions are transmitted to each functional module. The main controller uploads state information to the cloud server, and the cloud server analyzes the data through artificial intelligence algorithms and generates linkage rules. The system automatically adjusts the door lock state according to the linkage rules to realize intelligent control unlocking. That is, the quantum random number generator, millimeter wave radar, metabolic sensor, microphone, speaker, display screen, fingerprint module, and password keyboard are integrated into the smart door lock controller, which not only realizes new functions but also ensures that multiple ways can successfully unlock. The quantum random number generator is used to randomly generate dynamic unlocking instructions. The millimeter wave radar is used for lip micro-motion capture. The metabolic sensor is a combination of a piezoelectric microphone and a laser Doppler, which is used to detect the vibration frequency of the vocal cords mucosa.

[0056] Here, the quantum random number generator can be used to generate the above unlocking instruction word.

[0057] Step S204, obtaining the voice reading information obtained when reading the unlocking instruction word, and obtaining the lip movement information when reading the unlocking instruction word.

[0058] In this embodiment, after the user reads out the unlocking instruction word, the voice information captured by the built-in microphone of the smart door lock is transmitted to the main controller in real time for analysis. This step compares the user's voiceprint features with the pre-recorded voiceprints in the system database to confirm the user's identity. Voiceprint recognition technology can detect subtle differences in voice, even in noisy environments, and can maintain a high recognition rate.

[0059] When the user reads the instruction, the millimeter wave radar device of the smart door lock continuously monitors the micro-movement of the user's lips. The millimeter wave radar can penetrate slight obstructions such as masks and confirm whether the user has correctly read the instruction by monitoring the movement of the lips. The acquisition and analysis of lip movement information enhance the dual verification of voiceprint recognition, which can effectively prevent voice imitation and recording attacks.

[0060] In step S206, the opening verification is performed according to the voice reading information and the lip movement information, and an opening verification result is obtained.

[0061] The main controller comprehensively analyzes the voice reading information and the lip movement information to perform the opening verification. The verification process includes voiceprint matching, lip micro-movement model comparison, and metabolic state rapid detection. If the voiceprint matches and the lip movement information conforms to the instruction content, and the metabolic state (such as blood sugar level) is within the normal range, the verification is passed, and the smart door lock is unlocked. If any one of the verifications fails, the system will take corresponding measures, such as updating the instruction word to re-verify or recommending to use other unlocking methods, to ensure safety.

[0062] In step S208, the control mode of the smart door lock is determined according to the opening verification result.

[0063] In this embodiment, the smart door lock system determines the control mode according to the result of the opening verification. If the verification is successful, the door lock is automatically unlocked; if the verification fails multiple times, the system may trigger an emergency alarm process and transmit the current image and data to the administrator terminal; or after consecutive failures, the user is prompted to try alternative unlocking methods such as fingerprint unlocking, password unlocking, etc., to prevent security risks.

[0064] In step S210, the smart door lock is controlled according to the control mode.

[0065] In this embodiment, the smart door lock operates according to the determined control mode. After successful verification, the door lock is unlocked, allowing the user to enter; after verification failure, the door lock remains in a locked state and may start an alarm or recommend other unlocking methods to ensure that unauthorized access is prevented.

[0066] As can be seen from the above, in the embodiment of the present application, when the opening trigger instruction is detected, the opening instruction word is generated, wherein the opening instruction word is a word randomly generated and used to assist in opening; the voice reading information obtained when reading the opening instruction word is obtained, and the lip movement information when reading the opening instruction word is obtained; the opening verification is performed according to the voice reading information and the lip movement information, and the opening verification result is obtained; the control mode of the smart door lock is determined according to the opening verification result; and the smart door lock is controlled according to the control mode, achieving the purpose of generating an opening instruction word when detecting an unlocking demand, performing opening verification according to the voice reading information and the lip movement information of reading the opening instruction word, and improving the security of the smart door lock.

[0067] Therefore, by means of the technical scheme provided by the embodiments of the present application, the technical problem of the intelligent door lock in the related art being able to only perform identity verification on a single or simply combined biometric feature and having a security risk is solved.

[0068] According to the above-mentioned embodiments of the present application, detecting the unlocking trigger instruction comprises at least one of the following: determining that the unlocking trigger instruction is detected when a fingerprint component of the intelligent door lock detects fingerprint information; determining that the unlocking trigger instruction is detected when a password input component of the intelligent door lock detects password input information; and determining that the unlocking trigger instruction is detected when a voice detection component of the intelligent door lock detects voice information.

[0069] In this embodiment, the intelligent door lock is equipped with fingerprint, password and voice detection components. When a user places a finger on the fingerprint sensor, enters a password on the password keyboard or speaks a voice instruction in front of the microphone, the fingerprint recognition, password verification and voice recognition processes are triggered respectively, and through any one of the above ways, the system will generate an unlocking instruction item for further identity confirmation.

[0070] For example, when a family member approaches the door lock, the fingerprint sensor on the door lock detects the fingerprint in time, triggers the unlocking process, and the system generates a dynamic voice instruction, such as "please say today's date is October 1, 2023". After the member reads out the instruction, the system verifies it through the microphone and millimeter wave radar to ensure safe unlocking.

[0071] By providing multiple ways to trigger the generation of unlocking instructions, the user-friendliness and security of the system are enhanced, ensuring that even when one biometric recognition method is unavailable, the user can still initiate the identity verification process through other methods.

[0072] Here, through the integration of multiple unlocking trigger methods, not only the user experience is improved, but also the security level is increased, preventing the risks brought by relying on a single biometric recognition, such as fingerprint wear, password forgetting or voiceprint being recorded.

[0073] According to the above-mentioned embodiments of the present application, generating the unlocking instruction item comprises: dynamically generating the unlocking instruction item by a quantum random number generator.

[0074] Optionally, the quantum random number generator is a device that generates a truly random sequence of numbers using the principles of quantum mechanics, such as the random polarization characteristics of photons.

[0075] In this embodiment, the quantum random number generator generates unpredictable random numbers based on quantum physical processes, such as changes in the polarization state of photons. Such random numbers are used to fill dynamic variables in the unlocking instruction item, ensuring that each generated instruction is completely new and has nothing to do with any previous attempts by the user.

[0076] For example, when an employee is at work, the employee uses a dynamic instruction generated by a quantum random number generator for identity verification, such as a system-generated instruction "Please repeat this sentence: The company was founded in 1998", to ensure that each unlocking instruction is unique and to improve security.

[0077] Here, the use of the quantum random number generator is based on the uncertainty principle of quantum mechanics to generate truly random numbers for constructing the unlocking instruction word each time to prevent an attacker from unlocking illegally through recording or prediction algorithms.

[0078] Through the introduction of the quantum random number generator, the attack resistance of the smart door lock is greatly improved, especially in terms of preventing replay attacks. Even if an attacker records the user's voice, the attacker cannot predict or copy the instruction content for the next unlocking, ensuring the security and effectiveness of user identity verification.

[0079] Figure 4 is a flowchart of an optional smart door lock control method according to an embodiment of the present application, as shown in Figure 4 After a person triggers unlocking, the quantum random number generator randomly generates an unlocking instruction word. The specific operation is as follows: the door lock end generates 3 groups of parameters through the quantum random number generator: 3 language codes including Chinese / English / mixed, and semantic templates including time / weather / mathematical problems, such as "the current temperature is {random number} degrees".

[0080] According to the above embodiments of the present application, the voice reading information obtained when reading the unlocking instruction word is obtained, and the lip movement information when reading the unlocking instruction word is obtained, including: during the reading process of the unlocking instruction word, the voice reading information is obtained through the microphone of the smart door lock; during the reading process of the unlocking instruction word, the lip movement information is obtained through the millimeter wave radar of the smart door lock.

[0081] In this embodiment, after receiving the request for reading the instruction word, the smart door lock captures the user's voice reading information through the microphone, and the millimeter wave radar continuously monitors the lip micro-motion state when the user speaks. The system compares the real-time voice reading information with the voiceprint information pre-recorded by the user; at the same time, the lip model data generated by the millimeter wave radar is compared with the pre-stored lip model, to ensure that the voiceprint and the lip micro-motion are matched with the user.

[0082] For example, when a guest uses a voice instruction to unlock, the microphone and the millimeter wave radar of the door lock simultaneously capture the guest's voice and lip micro-motion for identity verification, which can accurately identify even in a low-light environment.

[0083] Here, the use of double biometric verification not only enhances the accuracy and anti-interference ability of identity recognition, but also prevents illegal unlocking attempts through voiceprint imitation or recording devices by detecting lip micro-movement, further improving the security of the system.

[0084] As shown in Figure 4 The door lock broadcasts and displays dynamic unlocking instruction words, and the person reads out the words in a low voice. The system performs a series of operations. The microphone acquires the voiceprint information of the person reading out the voice (i.e., voice reading information), and the millimeter wave radar acquires the lip movement information when the person reads out. The metabolic sensor acquires the vocal cord vibration frequency of the person.

[0085] According to the above embodiment of the present application, the unlocking verification is performed according to the voice reading information and the lip movement information, and the unlocking verification result is obtained, including: when the voice reading information and the lip movement information are both verified, it is determined that the unlocking verification result is unlocking verification success; when the voice reading information is verified and the lip movement information is not verified, it is determined that the unlocking verification result is unlocking verification failure; when the voice reading information is not verified and the lip movement information is all verified, the vocal cord vibration frequency when the unlocking instruction word is read out is obtained to assist the unlocking verification according to the vocal cord vibration frequency; when the voice reading information is not verified and the lip movement information is not verified, it is determined that the unlocking verification result is unlocking verification failure.

[0086] In this embodiment, after the user reads out the unlocking instruction, the intelligent door lock system compares the voice reading information and the lip movement information. If both are verified, it is determined that the unlocking verification is successful; if the voice reading information is verified but the lip movement information is not verified, or vice versa, it is determined that the unlocking verification is failed. When the voice reading information is not verified but the lip movement information is verified, the system will enter the auxiliary verification process, use the metabolic sensor to detect the vocal cord vibration frequency of the user, and judge whether the user is in a non-abnormal state, such as a non-drunk state, to determine whether the auxiliary unlocking verification is passed.

[0087] Here, the application of re-verification logic ensures that the system can effectively identify and respond to abnormal unlocking attempts, such as drunk state, coercion or illness, thereby more comprehensively protecting the safety of the user, while also reducing the false positives caused by changes in the user's state. That is, the judgment logic of the unlocking verification result. By comprehensively analyzing the voice reading information and the lip movement information, the system can more accurately determine whether it is a legal user, while also considering the possibility that the user may be in an abnormal state.

[0088] According to the above embodiment of the present application, the unlocking verification is performed according to the voice reading information, including: performing fragmentation processing on the voice reading information to obtain a plurality of voice segments; randomly selecting a predetermined number of target voice segments from the plurality of voice segments; and comparing each target voice segment with pre-recorded voiceprint information to perform unlocking verification on the intelligent door lock.

[0089] In this embodiment, when the user reads out the unlocking instruction word, the smart door lock receives the voice information through the microphone and performs fragmentation processing thereon, and randomly selects 3 50ms fragments for voiceprint recognition. The voiceprint features of each fragment are compared with the pre-recorded voiceprint information to confirm the user identity.

[0090] The application of the above random fragment voiceprint recognition technology improves the accuracy and robustness of voiceprint matching. Even in the case of poor user voice quality or high environmental noise, the recognition success rate can be improved through comprehensive analysis of multiple fragments, enhancing the user experience in various environments.

[0091] As shown in Figure 4 , the microphone obtains the voiceprint information read by the personnel, the system extracts the voice fragments of the user for data analysis, randomly selects 3 50ms voiceprint slice positions, and compares them with the pre-recorded voiceprint information in the database. If the matching is successful, one-third of the verification is completed, and if the matching fails, the item is displayed as not passed. The personnel state information is obtained to assist verification, i.e., the metabolic sensor obtains the frequency of the vocal cord vibration of the personnel.

[0092] Here, through fragmentation processing and random fragment selection, the difficulty of voiceprint recognition is increased, preventing illegal unlocking attempts through recording a single long fragment.

[0093] According to the above embodiment of the present application, the unlocking verification according to the lip movement information includes: generating a lip model according to the lip movement information; comparing the lip model with a pre-stored lip model, and comparing the lip movement data corresponding to the lip movement information with the unlocking instruction word, to verify the unlocking of the smart door lock.

[0094] In this embodiment, the lip micro-motion information when the user reads the instruction is obtained by a millimeter wave radar to generate a real-time lip model. The system compares this lip model with the pre-stored lip model, and matches the read lip movement data with the current instruction content to verify the user identity.

[0095] As shown in Figure 4 , the millimeter wave radar obtains the lip movement information when the personnel reads. The radar transmits a linear frequency modulated continuous wave and receives a return wave, which is processed by FFT to produce a personnel lip model. The personnel lip model is compared with the pre-stored personnel lip model in the database to confirm the target person. If the lip movement data matches the content of the word information, the verification is passed, completing two-thirds of the verification. Otherwise, the item is displayed as not passed, prompting a matching failure.

[0096] The lip micro-motion recognition function of the above-mentioned millimeter wave radar enhances the lip motion auxiliary verification in voiceprint recognition, and can accurately verify the identity by capturing the lip micro-motion information even in a low-light or completely dark environment, thereby expanding the use scenarios of the intelligent door lock and improving the user's convenience and safety in different environments.

[0097] Here, the lip motion information verification process of the millimeter wave radar is utilized. By synchronously verifying the lip model and the instructed lip motion data, the real-time and consistency of the user when reading the instructions are ensured, and the verification accuracy of the password execution is improved.

[0098] According to the above-mentioned embodiments of the present application, when the voice reading information verification fails and the lip motion information verification passes, the vocal cord vibration frequency when reading the unlocking instruction term is obtained, and the unlocking verification is assisted according to the vocal cord vibration frequency, including: determining the current state of the target object reading the unlocking instruction term according to the vocal cord vibration frequency; and assisting the unlocking verification according to the current state.

[0099] In this embodiment, when the intelligent door lock system determines that the voice reading information fails to pass the verification, but the lip motion information passes the verification, the system will detect the vocal cord vibration frequency of the user through the metabolism sensor to assist in judging whether the user is in a non-abnormal state, such as a non-drunk state. If the vocal cord vibration frequency shows that the user is in a normal state, the auxiliary unlocking verification passes; if it shows an abnormality, the user's state is re-acquired or a warning information is generated.

[0100] It should be noted that the metabolism sensor is a combination of a piezoelectric microphone and a laser Doppler. The 0.8mW laser Doppler detects the vibration of the vocal cord mucosa blood flow to detect blood sugar. For every 1mmol / L increase in blood sugar, the mucosa viscosity decreases, resulting in an increase of 0.7Hz in vibration frequency. The current state of the person is determined by detecting the vibration of the vocal cord mucosa blood flow through the laser Doppler, and the risk is effectively avoided.

[0101] The above-mentioned metabolism state detection of the vocal cord vibration frequency provides an non-invasive health monitoring function for the intelligent door lock system. It can effectively identify whether the user is in a drunk, coerced or sick state, not only enhancing the security protection of the door lock, but also increasing the attention to the user's health condition, embodying the humanized design of the intelligent device.

[0102] Here, through the detection of the vocal cord vibration frequency, the system can evaluate the current physiological state of the user, and thus decide whether to allow unlocking or take further warning measures.

[0103] According to the above-mentioned embodiments of the present application, the auxiliary unlocking verification according to the current state includes: when the current state indicates that the target object is in a non-abnormal state, determining that the auxiliary unlocking verification is passed; when the current state indicates that the target object is in a drunken state, re-acquiring the state information of the target object for auxiliary unlocking verification; when the current state indicates that the target object is in a coerced state, generating warning information; and when the current state indicates that the target object is in an ill state, acquiring the lip movement information of the target object and performing unlocking verification according to the lip movement information.

[0104] In this embodiment, in the auxiliary unlocking verification process, according to the user state reflected by the vocal cord vibration frequency, the intelligent door lock system will make corresponding responses. If the user is in a non-abnormal state, such as a sober state, the auxiliary verification is passed, and the door lock is unlocked; if the user is in a drunken state, the system will re-acquire the user state information to determine whether the auxiliary verification is passed; if the user is in a coerced state, the system will generate warning information, which may include sending an alarm to emergency contacts or security agencies; and if the user is in an ill state, the system will acquire the lip movement information of the user to determine whether the lip movement data can be relied on for unlocking verification.

[0105] For example, non-drunk / coerced / ill state. The detected person is in a non-abnormal state, and the verification is passed. Drunken state, judged by vocal cord vibration incoordination (fundamental frequency fluctuation > 15%) and blast tone ambiguity. Save the current image information, upload the data to the cloud, and the cloud will issue a notification to the emergency contact, which needs to pass a secondary confirmation to determine that the person is still sober. Coerced state, analyze the 6-8 Hz modulated signal generated by involuntary muscle tremor when speaking. Save the current image information, upload the data to the cloud, and the cloud will issue a notification to the emergency contact, which prohibits unlocking in any way. Ill state, the vibration frequency of the ill state is reduced, the amplitude is reduced, the vibration is irregular, and the closure is incomplete, so as to analyze and review the lip movement information to unlock.

[0106] Here, the intelligent evaluation of the user state enables the intelligent door lock system to respond more flexibly and safely to various unlocking requests. It not only prevents illegal unlocking when the user is in an abnormal physiological state, but also allows unlocking through additional verification means when the user is ill but conscious, which embodies the intelligence of the system and the sensitivity to user needs.

[0107] According to the above-mentioned embodiments of the present application, the intelligent door lock control method further includes: when it is determined that the unlocking verification result is unlocking verification failure, updating the unlocking instruction term to obtain a new unlocking instruction term; and re-performing unlocking verification using the new unlocking instruction term, and generating unlocking mode recommendation information when the number of re-verification reaches a predetermined number.

[0108] In this embodiment, when the system determines that the unlocking verification fails for multiple times (e.g., 5 times) in succession, the intelligent door lock system will stop the current biometric verification process and recommend to the user to use other unlocking methods, such as key unlocking, fingerprint unlocking, or password unlocking. If the user continues to attempt biometric unlocking and fails verification for multiple times (e.g., 3 times) in succession, the system will prompt the user to use the recommended unlocking method to ensure the safety of the door lock.

[0109] The processing mechanism of consecutive verification failure here enhances the usability and security of the intelligent door lock system. It can provide other unlocking methods in the case of user biometric changes or device malfunctions, ensuring that the user can safely and conveniently use the door lock in various situations, while also preventing potential illegal unlocking attempts and improving the overall protection capability of the system.

[0110] By recommending the use of other unlocking methods, the system can provide alternative solutions when the primary verification method fails, while avoiding potential security risks due to consecutive failures.

[0111] As shown in Figure 4 , the door lock broadcasts and displays dynamic unlocking instruction words, and the person reads out the words in a soft voice, and the system performs a series of operations:

[0112] S31: The microphone obtains the person's reading voiceprint information, the system extracts the user's voice segment for data analysis, randomly selects 3 50ms segment voiceprint slice positions, and compares them with the pre-recorded voiceprint information in the database. If the match is successful, one-third of the verification is completed, if the match fails, the item is not passed, and the personnel state information is obtained to assist in verification.

[0113] S32: The millimeter wave radar obtains the lip movement information when the person reads. The radar transmits a linear frequency modulation continuous wave and receives the echo, which is processed by FFT to produce a person's lip model. Compare it with the pre-stored person's lip model in the database to confirm the target person. If the lip movement data matches the content of the word information, the verification is passed and two-thirds of the verification is completed. Otherwise, the item is not passed and a match failure is prompted.

[0114] Then the door lock can be unlocked according to the matching state, which has the following four cases:

[0115] 1): S31 and S32 are all matched successfully, and the verification is passed.

[0116] 2): S31 is matched successfully, S32 is matched unsuccessfully, voiceprint analysis is passed, and lip movement recognition is not passed. It is determined that the user attempts to use audio to unlock. It is determined that the non-person is present, and the verification is not passed.

[0117] 3): S31 fails to match, S32 matches successfully, and S4 assists in verifying the state of the person.

[0118] 4):S31 and S32 all match failure, verification fails.

[0119] When the verification is successfully unlocked, the verification fails to prompt the failure item and update the instruction word item to re-read the judgment, and after the verification fails for 3 times, it is prompted to recommend to use other unlocking methods (key unlocking / fingerprint unlocking / password unlocking). After 5 times of verification failure, an alarm is broadcast, the current image is saved and the data is transmitted to the master mobile terminal to prompt a warning.

[0120] Through the technical scheme provided by the above embodiment of the application, when the user triggers the unlocking demand, the door lock generates a dynamic semantic sentence based on quantum dynamic voiceprint + lip radar imaging + metabolic state rapid detection, the user speaks the dynamic content, the door lock identifies the user's voiceprint. The millimeter wave radar transmits a linear frequency continuous wave and receives the echo for data processing to identify the lip micro-motion. The metabolic sensor identifies the state of the person by inversely deducing the blood glucose concentration from the vocal cord mucosa vibration, and finally effectively unlocks the door lock by combining the verification. Since it is not a single fixed sentence, the system can automatically adjust the device behavior according to the dynamic. The human biological living body recognition can confirm the current state according to the user dynamic. In addition, the voiceprint door lock system based on the fusion of metabolic characteristics and lip motion is realized by using the technical scheme, and the dynamic voiceprint technology driven by quantum random numbers is used to improve the security of voiceprint unlocking; the millimeter wave radar device is used to verify the lip micro-motion synchronously to strengthen the double verification of voiceprint unlocking; the non-invasive metabolic state detection unit based on vocal cord mucosa vibration is used to detect the state of the person unlocking; the present application can improve the accuracy of user voice collection in various conditions such as high noise, dark light, and small sound energy. At the same time, the intelligent level and user experience of the intelligent door lock system are significantly improved, and the intelligent and convenient use and safety of the intelligent door lock are also realized.
