In the mapping relationship between the characteristic parameters and wind speed, each characteristic parameter corresponds to one or more numerical ranges, such as a certain range The frequency and duration correspond to a wind speed level; or set the maximum wind speed V of the air conditioner, set the mapping relationship between the characteristic parameters and wind speed, and determine the percentage of the wind speed Vi corresponding to each characteristic parameter to the maximum wind speed V.

Step S30, the control terminal generates a wind speed adjustment command according to the determined wind speed, and sends the wind speed adjustment command to the air conditioner, so that the air conditioner operates according to the determined wind speed.

In this embodiment, the control terminal can determine the control code corresponding to the wind speed according to the mapping relationship between the wind speed and the control code, encode the control code to generate a wind speed control command, and send the wind speed control command to air conditioner; or the control terminal directly encodes the obtained wind speed to generate a wind speed control command. corresponding control code, and respond to the determined control code.

In the method for controlling the wind speed of an air conditioner proposed in this embodiment, the user blows air to the control terminal to generate a corresponding audio signal, and the control terminal extracts a preset first type of audio signal from the audio signal; the control terminal obtains the The characteristic parameters of the first type of audio signal and according to the preset mapping relationship between the characteristic parameters and the wind speed, determine the wind speed corresponding to the acquired characteristic parameters, and generate a wind speed adjustment instruction according to the determined wind speed, and adjust the wind speed An instruction is sent to the air conditioner so that the air conditioner operates according to the determined wind speed. By directly controlling the wind speed of the air conditioner based on the audio signal parameters generated by the user blowing air, the control of the air conditioner is more accurate.

Further, in order to improve the accuracy of wind speed control, the step S20 specifically includes: when the first type of audio signal meets a preset condition, the control terminal obtains the characteristic parameters of the first type of audio signal , and according to the preset mapping relationship between the characteristic parameters and the wind speed, determine the wind speed corresponding to the obtained characteristic parameters.

Since the user may generate sound waves during speaking or other activities, it is determined whether the first type of audio signal satisfies a preset condition when the first type of audio signal is extracted, and the preset condition may be is the duration and/or amplitude of the audio signal, and when the preset condition is the duration, the preset condition is met: the duration of the first type of audio signal is greater than or equal to the preset duration; When the condition is the amplitude, the preset condition is satisfied that the amplitude of the first type of audio signal is less than or equal to the preset amplitude. When the first type of audio signal meets the preset condition, the control terminal obtains the characteristic parameters of the first type of audio signal; when the first type of audio signal does not meet the preset condition, the control terminal may not respond to the first type audio signal, or can generate a prompt message to prompt the user that the wind speed control fails, and the prompt message can be a light signal or a sound signal.

Further, in order to improve the accuracy of wind speed control, step S30 includes:

Step S31, the control terminal determines the time interval between the currently received audio signal and the previously received audio signal;

Step S32, when the determined time interval is greater than the preset threshold value, the control terminal generates a wind speed adjustment instruction according to the determined wind speed, and sends the wind speed adjustment instruction to the air conditioner for the air conditioner to follow the determined wind speed operation.

Since there is a situation where a person changes air midway during the blowing process, after determining the wind speed corresponding to the acquired characteristic parameter according to the preset mapping relationship between the characteristic parameter and the wind speed, the control terminal determines that the currently received The time interval between the audio signal and the previously received audio signal. When the determined time interval is greater than the preset threshold value, it means that the user re-controls the wind speed of the air conditioner instead of ventilation. At this time, the control terminal directly obtains the The received wind speed generates a wind speed adjustment instruction, and sends the wind speed adjustment instruction to the air conditioner, so that the air conditioner operates according to the determined wind speed.

Further, after step S31 includes:

When the determined time interval is less than or equal to the preset threshold value, the control terminal generates a wind speed increase command according to the acquired wind speed, and sends the wind speed increase command to the air conditioner for the air conditioner to use according to the acquired wind speed. The fan speed adjustment air conditioner increases the current running fan speed.

After determining the wind speed corresponding to the acquired characteristic parameter according to the preset mapping relationship between the characteristic parameter and the wind speed, the control terminal determines that the time interval between the currently received audio signal and the previously received audio signal is less than or equal to When the preset threshold value is set, it means that the user is only exchanging air. At this time, the control terminal generates a wind speed increase command according to the acquired wind speed, and sends the wind speed increase command to the air conditioner for the air conditioner to follow. The obtained wind speed adjusts the air conditioner to increase the current running wind speed.

In this embodiment, when the air conditioner adjusts the wind speed, it can directly increase the obtained wind speed on the basis of the current operating wind speed, for example, the current operating wind speed of the air conditioner is 20% V, where V is the maximum wind speed of the air conditioner, and In the wind speed increase command received, if the wind speed is 10%V, the air conditioner adjusts the current operating wind speed to 30%V.

Those skilled in the art can understand that, in order to improve the accuracy of voice control, when an audio signal is detected, the control terminal extracts the preset audio signal of the first type from the audio signal, and acquires the first audio signal. The characteristic parameters of the type of audio signal, the control terminal determines the time interval between the detected audio signal and the last detected audio signal, and when the determined time interval is less than or equal to the preset threshold value, the control terminal will The characteristic parameters of the audio signal obtained last time are combined with the characteristic parameters of the currently detected audio signal to generate new characteristic parameters, and according to the mapping relationship between the preset characteristic parameters and wind speed, the generated characteristic parameters are determined. Corresponding to the wind speed, the control terminal generates a wind speed adjustment command according to the determined wind speed, and sends the wind speed adjustment command to the air conditioner, so that the air conditioner operates according to the determined wind speed.

Further, in order to enrich the functions of the air conditioner, after step S10, further steps are included:

When extracting a preset first-type audio signal from the audio signal fails, the control terminal extracts a preset second-type audio signal from the audio signal;

The control terminal sends the audio signal of the second type to the air conditioner, so that the air conditioner can respond to the received audio signal.

In this embodiment, the audio signal received by the air conditioner may be a voice control command, or may be an audio signal generated by the user blowing on the voice pickup device, so the preset first audio signal is extracted from the audio signal at the control terminal. When the type of audio signal fails, it means that the detected voice signal may be a voice control instruction. At this time, a preset second type of audio signal is extracted from the audio signal, and the second type of audio signal can be a preset an audio signal in a second frequency range, the second frequency range may be a human voice frequency.

The preset first type audio signal may be an audio signal within a preset first frequency range or an audio signal within a preset first frequency range and a preset first amplitude range. When the preset audio signal of the first type is an audio signal in the first frequency range, the control terminal can obtain the audio signal in the preset first frequency range through a band-pass filter; or the control terminal can obtain the audio signal in the preset first frequency range through a low-pass filter filter and high-pass filter to obtain the audio signal within the preset first frequency range, that is, the audio signal with higher frequency is filtered out by the low-pass filter, and then the audio signal with lower frequency is filtered out by the high-pass filter to obtain the preset An audio signal within a first frequency range is assumed. In this embodiment, the preset first frequency range can be set by the user, and the preferred solution is the human blowing frequency range, which can be obtained through multiple experiments.
