Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and in particular to a voice control method, device, fan, and medium for intelligent home appliances. Background Technology

[0002] With the development of smart homes, smart home appliances with functions such as voice recognition and remote control are gradually becoming more common. However, air conditioners, as home appliances with a long service life, have a much slower replacement cycle than consumer electronics, and most households are still using traditional air conditioners without smart features. Although smart air conditioners are available on the market, their high price and replacement costs limit their adoption rate.

[0003] Existing voice remote controls are independent "remote control" devices that control smart home appliances by receiving voice commands and emitting infrared signals. These devices are typically small, have limited functionality, and require manual placement by the user near the target smart appliance (such as an air conditioner) to ensure stable infrared signal transmission. However, this "remote control" method suffers from limited infrared signal coverage and susceptibility to obstruction, resulting in lower control accuracy. Furthermore, the need for additional purchase increases costs. Summary of the Invention

[0004] This invention provides a voice control method, device, fan, and medium for smart home appliances, aiming to solve the problem of low accuracy in existing voice control of smart home appliances.

[0018] Please see Figure 1 , Figure 1 This is a flowchart illustrating a voice control method for a smart home appliance according to an embodiment of the present invention. The voice control method for the smart home appliance will be described in detail below. Figure 1 As shown, the method includes the following steps S110-S130.

[0019] S110. Obtain the user's voice command and identify the device type identifier and control command in the voice command.

[0020] In this embodiment of the invention, the fan includes a control module, which includes a voice recognition module. After the user issues a voice command, the voice recognition module acquires the voice command, recognizes the voice command to obtain the device type identifier and control command. It should be noted that, in this embodiment, in addition to controlling the fan motor drive and displaying button interaction, the control module also includes an infrared emitting module 11, an infrared receiving module 12, a microphone, a speaker, and a power management module. The infrared emitting module 11 converts the electrical signal into an infrared light signal with a specific carrier frequency (e.g., 38kHz) through an infrared emitting diode 111 and emits it. The infrared receiving module 12 has a built-in photodiode and demodulation circuit, which is responsible for receiving the infrared signal and converting it into a TTL level signal that the control module can recognize. The power management module supplies power to the infrared emitting module 11, the infrared receiving module 12, the control module, the speaker, the microphone, and the voice recognition module. Its design is flexible, and it can be powered by an AC adapter or a battery solution for portable use. It should also be noted that in this embodiment, the fan further includes a fan body, whose basic components include a motor, fan blades, and a housing. The motor, as a power source, converts electrical energy into mechanical energy, driving the fan blades to rotate at high speed. The fan blades are typically made of plastic or metal, and their specific shape design (such as an arc) is crucial for cutting through the air and generating the desired wind direction and volume. The housing not only supports and integrates all components, forming a stable overall structure, but also protects the internal modules, such as the motor, from external damage. The aforementioned motor, fan blades, and housing work together to achieve the basic air delivery function of a traditional fan.

[0021] In one embodiment, such as this embodiment, the fan includes a fan head and a body; the infrared emitting module 11 includes at least four infrared emitting diodes 111, such as... Figure 2 and 3 As shown, the infrared emitting diodes 111 are distributed in a surrounding pattern on multiple sides of the fan head or around the body. It should be noted that in this embodiment, when the fan enters the working state, its rotatable fan head or body drives the domestic and international emitting modules to rotate synchronously, constructing a dynamically sweepable 360-degree omnidirectional infrared signal transmission network. By optimizing the installation angle, emission tilt angle, and power of each diode, the infrared signal transmission network can achieve uniform spatial signal coverage and three-dimensional enhancement during fan operation, thereby automatically forming a wide-area, dead-angle-free control signal coverage field, fundamentally eliminating signal blind spots and obstruction failures caused by fixed installation or single-point transmission. It should also be noted that in this embodiment, the infrared receiving module 12 is mounted on the body.

[0022] In this embodiment, such as Figure 4 As shown, step S110 specifically includes steps S111-S112: S111. Perform speech recognition processing on the voice command and extract speech features; S112. Match the voice features with a preset voice command library to determine the device type and the control command.

[0023] In this embodiment of the invention, the acquired voice commands are first preprocessed, including pre-emphasis to enhance high-frequency components and frame-by-frame windowing (typically using a frame length of 25 milliseconds and a frame shift of 10 milliseconds) to reduce spectral leakage. Next, a feature extraction algorithm (such as Mel-frequency cepstral coefficients, MFCC) is used to convert the preprocessed voice commands into feature parameters that better characterize the voice content. This process simulates human hearing characteristics and is achieved through steps such as calculating the power spectrum, passing through a Mel-filter bank, taking the logarithm, and performing a discrete cosine transform. Then, the extracted voice features are matched against a pre-defined voice command library. Specifically, by calculating the similarity between features, the target device type identifier corresponding to the voice command and the specific control command (such as "power on" or "temperature adjustment") are parsed out.

[0024] S120. Determine the target control device based on the device type identifier, and generate a control signal based on the target control device and the control command.

[0025] In embodiments of the present invention, such as Figure 5As shown, step S120 specifically includes steps S121-S125: S121, if the device type identifier is a first control device type identifier, then the first control device is determined as the target control device; S122, if the device type identifier is a second control device type identifier, then the second control device is determined as the target control device; S123, if the target control device is the first control device, then a coding protocol matching the first control device is determined from a pre-stored first device control protocol library; S124, if the target control device is the second control device, then a coding protocol matching the second control device is determined from a pre-stored second device control protocol library; S125, the control signal is generated according to the coding protocol and the control instruction. Specifically, when the device type identifier is parsed as a first control device type identifier (for example, the instruction keywords explicitly contain identifiers strongly related to air conditioning devices such as "air conditioner" or "cooling"), the decision logic is directed to the first control device, and it is determined as the target control device for this instruction, that is, the execution process for infrared-controlled air conditioning is initiated. Accordingly, if the parsed device type identifier is a second control device type identifier (for example, the instruction contains words such as "fan" or "electric fan"), the target control device is identified as the second control device, and the control process for the fan is initiated. This classification clearly distinguishes the control intent and prevents instruction confusion. After the target control device is identified, the protocol matching and instruction generation stage begins. For cases identified as the first control device (air conditioner), the system further retrieves and determines the uniquely matching encoding protocol from a pre-stored first device control protocol library (such as an air conditioner infrared encoding protocol library) based on the air conditioner's brand, model, and other information. The first device control protocol library contains encoding rules for mainstream air conditioner brands and can be expanded through self-learning. If the target control device is the second control device (fan), the system queries the pre-stored second device control protocol library. This library stores encoding protocols used to directly control internal components such as fan motors, oscillation mechanisms, and lights. Finally, specific control signals are generated based on the determined encoding protocol and control instruction content. For air conditioners, control signals are generated by encoding control commands (such as "set to 26 degrees") into corresponding infrared carrier pulse sequences according to a matching encoding protocol. For fans, the commands are converted into electrical signals that adjust the motor's PWM duty cycle, relay switches, and other functions.

[0026] S130. The control signal is sent to the target control device through the infrared emitting module.

[0027] In this embodiment of the invention, the control signal is modulated by the main control unit and drives the infrared emitting module to convert the electrical signal into an infrared light signal with a specific carrier frequency (such as 38kHz). The signal is then radiated into the space of the target control device (such as an air conditioner) through a group of infrared emitting diodes distributed on the fan, so as to realize remote non-contact control.

[0028] In one embodiment, such as this embodiment, the voice control method for smart home appliances further includes: if the encoding protocol of the first control device is not found in the pre-stored first device control protocol library, then a remote control learning mode is activated; an infrared signal sent by a remote control matching the first control device is received through the infrared receiving module; if the infrared signal meets preset analysis and verification conditions, an encoding protocol corresponding to the infrared signal is generated, and the encoding protocol is saved to the first device control protocol library. Specifically, when the target control device is determined to be the first control device (such as an air conditioner), if no encoding protocol matching the brand or model of the first control device is found in the pre-stored first device control protocol library, then a remote control learning mode is activated. After entering the remote control learning mode, the user will be guided to operate through voice or screen prompts, such as: "Please point the air conditioner remote control at this device and press and hold the 'on / off' button." At this point, the infrared receiving module starts working to capture the infrared light signal emitted by the air conditioner remote control. After converting the infrared light signal into an electrical signal, it sends it to the main control module. The main control module uses a high-precision timer to measure the duration of each high-level and low-level pulse in the electrical signal (usually accurate to the microsecond level), thereby recording the complete infrared coded waveform timing information. The captured timing information is then analyzed to verify whether it meets preset analysis and verification conditions. These conditions include: determining if the electrical signal contains a reasonable start code (usually a relatively long low-level lead pulse), checking the integrity of the data frame structure, verifying that the encoding format conforms to common infrared protocol specifications, and confirming that its carrier frequency is within a typical range (e.g., 36kHz to 40kHz). Only after the timing information verification passes will a unique digital fingerprint be generated based on the electrical signal. This digital fingerprint is then associated with the air conditioner's brand and model to form an encoding protocol, which is saved to the first device control protocol library for future updates. Understandably, when the user issues a command to control the first control device again, the corresponding encoding protocol can be quickly invoked by matching the digital fingerprint, enabling reliable control of the target device.

[0029] In one embodiment, such as this embodiment, the voice control method for smart home appliances further includes: if the target control device is the first control device and the control signal is to turn on the first control device, then a preset function of the second control device is simultaneously activated to achieve linkage control between the first control device and the second control device. Specifically, when a user command to turn on the first control device (such as an air conditioner) is detected, the control module, while sending a control signal to the air conditioner, will automatically send a start command to the second control device (such as a fan) based on preset collaborative logic. For example, after the user issues a voice command to "turn on the air conditioner," not only will the air conditioner be turned on via the infrared transmitter module, but the fan's airflow function will also be activated immediately, achieving a linkage effect of "air conditioner cooling and fan simultaneously promoting air circulation." This deep collaborative control relies on the scenario-based judgment logic integrated within the control module to ensure that under specific conditions (such as the "turn on" command), multiple devices can work together organically, thereby improving overall comfort and reducing the tediousness of step-by-step operation for users, truly realizing an intelligent and scenario-based home control experience.

[0030] In one embodiment, such as this embodiment, the voice control method for smart home appliances further includes: acquiring indoor ambient temperature and humidity data, and automatically adjusting the first control device and the second control device based on the temperature and humidity data. Specifically, an integrated temperature and humidity sensor module collects indoor ambient temperature and humidity data in real time, wherein the temperature and humidity data includes indoor temperature and indoor humidity. The temperature and humidity data are compared with a user-preset temperature and humidity threshold (e.g., the temperature threshold is set to 26°C) to obtain a comparison result. Based on the comparison result, an autonomous decision is made: when the indoor temperature is detected to be higher than the temperature threshold, an instruction is automatically sent to the first control device (such as an air conditioner) to switch it to cooling mode; simultaneously, when the indoor temperature is detected to have fallen back to a comfortable range, the air conditioner is automatically turned off, and the second control device (fan) is started for energy-saving ventilation. This closed-loop control logic based on environmental perception can go beyond simply responding to instructions and achieve proactive and adaptive environmental adjustment without user intervention.

[0031] In one embodiment, such as this one, the voice control method for smart home appliances further includes: if a remote control command is received, controlling the first control device or the second control device according to the remote control command; or updating the first device control protocol library. It should be noted that in this embodiment, the fan integrates a Wi-Fi communication module, enabling it to access the internet. Users can send remote control commands to the fan via a dedicated application (APP) on their mobile phones, through a home wireless network or mobile data network. These commands are transmitted via TCP / IP protocol, received and decoded by the fan's Wi-Fi communication module, and then sent to the control module, thereby enabling remote control of the fan itself (e.g., on / off, fan speed adjustment) or external devices such as air conditioners connected via infrared signals. Furthermore, the Wi-Fi module also maintains a communication connection with the cloud server, enabling online downloading and updating of the built-in first device control protocol library (air conditioner remote control coding rule protocol library). This function ensures continuous learning and compatibility with newly launched air conditioner brands and models, greatly improving the product's adaptability and long-term availability.

[0032] To facilitate understanding, the implementation process of voice control methods for smart home appliances is illustrated with an example below: When a user issues a voice command, the fan's built-in microphone array collects the voice signal. After preprocessing, the voice recognition module analyzes the signal to obtain the device type identifier and control command. The control module then determines the target control device based on the device type identifier and control command, generates a control signal, and sends the control signal to the target control device via an infrared transmitter module to control the device. Upon first use, users need to enter the wake-up process using a specific wake-up word and the command "match air conditioner". After being woken up, a voice prompt will say, "Please say the name of your air conditioner brand". After the user says the brand name, the voice recognition module sends the result to the control module. The control module searches its built-in device control protocol library. If the corresponding brand is found, it establishes an association and confirms the successful match via voice, completing the initial binding.

[0033] Once the brand is successfully matched, the user can enter the normal control mode. The device is activated by uttering a voice command containing control instructions (such as "turn on the air conditioner" or "set to 26 degrees"). After the voice recognition module recognizes the control command, the control module retrieves the complete encoding protocol of the matched brand from the device control protocol library, generates the corresponding control signal, and sends it via the infrared transmitter module to control the target air conditioner.

[0034] For air conditioner brands not covered in the device control protocol library, intelligent learning can be implemented. After the user enters the learning mode via voice, the system will guide them step-by-step to point the original air conditioner remote control at the device and press the buttons to be learned in sequence (such as power on, power off, mode, temperature, etc.). The infrared receiving module will capture the original infrared signal from the remote control and analyze and verify it by analyzing key parameters such as carrier frequency, pulse sequence, and data frame structure to confirm the integrity and validity of the signal. To ensure the reliability of the learning, each button signal is usually sampled and compared at least twice, and is only considered valid if the two results match. After successful verification, the control module will generate a unique digital fingerprint, associate this digital fingerprint with the air conditioner's brand and model to form an encoding protocol, and save the encoding protocol to the first device control protocol library to expand the library. During the learning process, the system will also provide real-time voice feedback on the current progress and results.
