Description

Technical Field

[0001] This application relates to the field of door lock technology, and in particular to an intelligent voice command door lock device and control method. Background Technology

[0002] In the field of smart homes, smart voice command door lock devices and control methods are an important technological innovation. As people's demand for home security and convenience continues to increase, traditional door lock systems can no longer meet people's needs.

[0003] Traditional door lock systems typically use physical keys to unlock, but this presents several problems. First, physical keys are easily lost or stolen, posing a potential risk to home security. Second, unlocking with a physical key requires manual operation, which is inconvenient. Furthermore, traditional door locks cannot achieve remote control and intelligent management, nor can they be linked with other smart home devices.

[0004] To address these issues, the invention of intelligent voice command door lock devices and control methods has emerged. This technology utilizes voice recognition technology and an intelligent control system to enable functions such as unlocking, locking, and remote control using voice commands. Users can easily control the door lock simply by using voice commands, improving home security and convenience.

[0005] In addition, smart voice door lock devices can also be linked with other smart home devices, such as smart speakers and smartphones, to achieve more intelligent functions. For example, users can remotely monitor the door lock status, set temporary passwords, and view unlocking records through their smartphones.

[0006] However, current smart voice door locks usually use fingerprint recognition or password unlocking. When using fingerprint recognition, it is easy to encounter situations where the fingerprint gets wet or there are air bubbles on the finger, resulting in unclear fingerprint recognition. Voice recognition is not yet mature. If there is an accent or if it is not the same person who wakes it up, it will not be able to wake up the device to work, and the unlocking is not smart enough.

[0049] Reference Appendix Figure 1-2 This is a flowchart of an intelligent voice command door lock device and control method according to an embodiment of this application;

[0050] Example 1

[0051] A smart voice command door lock device and control method, the device includes a front component, a rear component, a lock cylinder connector and a main board 7;

[0052] The front component is adapted to the rear component;

[0053] The front component and the rear component are connected in series via the lock cylinder connector;

[0055] The motherboard 7 has a speaker and a radio 8 for receiving user commands and voice feedback.

[0056] The front component includes a front handle 1, a front cover plate 2, and a front collection groove;

[0057] The front collection groove has a space inside, the front cover plate 2 is adapted to the front collection groove, and both the front cover plate 2 and the front collection groove are provided with through holes, and the front handle 1 is inserted into the through holes.

[0058] The rear component includes a rear handle 4, a rear cover plate 5, and a rear collection groove 3;

[0059] The rear collection groove 3 has a space inside, and the rear cover plate 5 is adapted to the rear collection groove 3 to form a space. Both the rear cover plate 5 and the rear collection groove 3 are provided with through holes, and the rear handle 4 is inserted into the through holes.

[0060] The lock cylinder connector includes a lock head 9 and a connecting shaft 10. One end of the lock head 9 is connected to the front handle 1, and the other end of the lock head 9 is connected to the connecting shaft 10. The other end of the connecting shaft 10 is connected to the rear handle 4. The lock head 9 and the connecting shaft 10 are interlocked through through holes.

[0061] Specifically, the door lock device is installed on the door, the main board 7 is set in the front slot, and a fingerprint reader 6 is located below the main board 7. Users can turn the handle to open the door, enter a password, or use fingerprint recognition, or use voice recognition. The door can be opened by receiving the user's voice information through a speaker and a microphone. The door can also be opened and closed via an APP.

[0062] In this embodiment, a battery 11 is also included, which is disposed on the rear collection slot 3, and the microphone 8 is disposed on the rear cover plate 5.

[0063] A smart voice command door lock control method, wherein the control method is as follows:

[0064] The voice storage module is used to store voice commands;

[0065] The voice recognition module is used to receive and recognize the user's voice commands;

[0066] The control module, connected to the door lock body and the voice recognition module, is used to control the locking or unlocking operation of the door lock body according to voice commands;

[0067] The communication module, connected to the control module, is used to communicate with other smart home devices.

[0068] In one embodiment,

[0069] Receive user voice commands;

[0070] Recognize the received voice commands;

[0071] Control the locking or unlocking operation of the door lock based on the recognition result;

[0072] Communicate with other smart home devices.

[0073] In this embodiment, during the step of recognizing the received voice commands,

[0074] Receive user voice commands;

[0075] Preprocess the received voice commands;

[0076] The preprocessed voice commands are compared with the pre-stored voice patterns.

[0077] The user's operational intent is determined based on the comparison results.

[0078] Specifically, it receives user voice commands: the smart voice door lock receives user voice commands via a microphone or other voice receiving device;

[0079] Preprocessing voice commands: The received voice commands are preprocessed, including noise removal and reduction of voice variability, to ensure the accuracy of subsequent voice recognition.

[0080] Pre-stored voice modes: In smart voice door lock devices, a series of known voice modes are pre-stored, such as complex voice commands like "open the door," "close the door," and "set a password," as well as voice commands with higher security levels.

[0081] Compare the preprocessed voice commands with the pre-stored voice patterns: The preprocessed voice commands are compared with the pre-stored voice patterns; this can be achieved by converting the voice commands into digitized voice feature vectors and comparing their similarity with the pre-stored voice pattern feature vectors.

[0082] Determine the user's intention: Based on the comparison results, determine the user's intention; if the preprocessed voice command highly matches a pre-stored voice pattern, then the user's intention can be determined to be the operation represented by that voice pattern.

[0083] Perform corresponding operations: Based on the determined user operation intention, the smart voice door lock device performs corresponding operations, such as opening the door, closing the door, setting a password, etc.

[0084] By comparing pre-processed voice commands with pre-stored voice patterns, smart voice door lock devices can accurately recognize users' voice commands, thereby achieving precise door lock control. This method can improve the reliability and user experience of smart voice door lock devices, allowing users to easily control the operation of the door lock through simple voice commands.

[0085] Most importantly, data collection is crucial. First, it is necessary to collect the voice data of each family member, including the child's accent characteristics. This can be done by asking each family member to say a series of specific instructions, such as "open the door" or "close the door," while recording their voice samples. These samples can include different accents, pronunciation habits, and speech rates.

[0086] Data preprocessing: The collected speech data is preprocessed, including noise removal, volume reduction, and feature extraction. The purpose of preprocessing is to convert the speech data into a machine-processable form for subsequent model training.

[0087] Feature extraction: Extracting useful features from preprocessed speech data; commonly used feature extraction methods include Mel frequency cepstral coefficients (MFCC), linear predictive coding (LPC), etc.; these features can capture the sonic characteristics of speech, such as frequency, intensity, and sound variations;

[0088] Model training: Use extracted features and corresponding labels (instructions) to train a personalized model; machine learning algorithms (such as support vector machines, random forests, etc.) or deep learning algorithms (such as convolutional neural networks, recurrent neural networks, etc.) can be used for model training; during the training process, the child's speech data and corresponding labels are input into the model so that it learns the association between the child's accent characteristics and the corresponding instructions;

[0089] Model optimization: Through iterative training and validation, the personalized model is optimized; the model parameters, network structure, and training strategies can be adjusted to improve the model's accuracy and robustness.

[0090] Model application: The trained personalized model is embedded into the smart voice door lock device; when the child says the voice command "open the door", the device will prioritize using the child's personalized model for matching, thereby improving recognition accuracy.

[0091] In this embodiment, a communication connection is established with other smart home devices;

[0092] Transmit door lock status information to other smart home devices;

[0093] It can receive instructions from other smart home devices and execute corresponding operations.

[0094] Specifically, when family members return to their home, they can say "open the door" using a voice command. The smart voice door lock device will receive and preprocess this voice command. Then, it will compare the command with a pre-stored voice pattern. If the match is successful, the door lock will automatically unlock, and family members can enter the house.

[0095] Guest visits: When guests arrive, they can ring the doorbell and say "I'm here to visit" via voice command; the smart voice door lock device will receive and preprocess this voice command and compare it with the pre-stored voice patterns; if the match is successful, the door lock will unlock and allow the guest to enter;

[0096] Setting a door lock password: Family members can say "set password" via voice command. The smart voice door lock device will receive and preprocess this voice command. Then, it will compare the command with the pre-stored voice pattern. If the match is successful, the door lock will enter the password setting mode, and family members can set a new door lock password via voice command.

[0097] Remote control: Family members can send voice commands, such as "open the door" or "close the door," via a mobile app or other remote control methods. The smart voice door lock device will receive and preprocess the voice command and compare it with a pre-stored voice pattern. If the match is successful, the door lock will perform the corresponding operation according to the command, such as remotely opening or closing the door.

[0098] By using smart voice door lock devices in the home environment, the method of comparing pre-processed voice commands with pre-stored voice patterns can provide a convenient door lock control method. Family members and visitors can use simple voice commands to open and close the door, set passwords, and perform other operations, enhancing the intelligence of the door lock and the user experience.
