Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the invention and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the invention.
An embodiment of the invention provides a kitchen noise reduction method, a refrigerator and a computer readable storage medium, which actively reduce noise of electrical equipment in a kitchen through the refrigerator, improve the operating environment of the kitchen, improve the use experience of a user and enable the kitchen to be more intelligent.
Fig. 1 is a method of kitchen noise reduction according to an embodiment of the present application, and although the present application provides the method operation steps described in the following embodiments or flowcharts, the method is based on conventional or non-creative labor, and there is no logically necessary causal relationship in the steps, and the execution sequence of the steps is not limited to the execution sequence provided in the embodiments of the present application.
Specifically, the method comprises the following steps:
step 101: acquiring a noise combination of noise equipment in a kitchen in an operating state;
here, it is assumed that there are a plurality of devices in the kitchen, where n devices have large noise in the operating state, noise generated by the n devices needs to be reduced, and the devices that have large noise and need to be reduced are noise devices, i.e., n noise devices in total; obtaining noise equipment in a kitchen in an operating state, and assuming that m noise equipment in the operating state are provided, knowing that m epsilon (0, n), namely that the noise equipment in the operating state is less than or equal to all the noise equipment.
The working state refers to the operating state of the device after the device is electrified and operated, such as the state after the range hood starts to exhaust air, the state when the microwave oven and the oven are heating food, the state when the dish washer washes dishes, and the like.
And because the different devices are distinct, each device in the noise combination is a deterministic device, and the noise combination formed by the noise devices in operation is a deterministic device combination, and any device in the noise combination is no longer a deterministic device if replaced by another device.
Step 102: acquiring noise reduction information corresponding to the noise combination, particularly as discussed below;
step 103: and sending out corresponding noise reduction sound waves according to the noise reduction information.
Setting n noise devices in a kitchen, enabling a user to reduce noise of m noise devices in a working state, acquiring noise reduction information corresponding to noise combinations formed by the m noise devices, enabling the noise reduction information to correspond to the noise emitted by the m devices in the working state, and enabling the noise emitted by the electrical equipment to be smaller for the person by playing noise reduction sound waves when the combination of the m devices is in the working state, namely indicating that the noise corresponding to the combined noise information is emitted at the moment.
The present disclosure is different from the prior art, in which noise reduction information is corresponding to a preset noise combination, and when the noise reduction information is met, noise reduction sound waves corresponding to the noise reduction information are played again, and the playing of the noise reduction sound waves is not collected in real time but directly called. The noise-reducing sound wave is emitted without being continuously regulated according to the noise sound wave, no time delay exists between the noise sound wave and the noise-reducing sound wave, the existing active noise reduction needs to be converted into noise-reducing information after the noise sound wave is detected, the sound wave at the next moment is detected, and the noise is reduced, so that the noise reduction effect is influenced due to the fact that delay exists in the middle of the sound wave at the next moment. The noise reduction process of the embodiment is stable, delay is less, and action response is rapid.
On the other hand, because the noise of the electrical equipment is generally relatively stable, the formed frequency spectrum information of the sound is also stable, the noise of the electrical equipment is relatively easy to reduce by an active noise reduction mode unlike the sound information of the human speaking which changes at any time, noise reduction sound waves of the noise reduction information corresponding to the noise combination are played when the noise is in line with the condition, the experiment detection can obviously reduce the noise of the environment, meanwhile, the embodiment does not reduce the noise of the human voice, the television voice of the object and other sounds, the operation of the people working in the kitchen under the environment which is not disturbed by the noise of the electrical equipment in the kitchen is ensured, and the sound requirement of normal life is not influenced. The embodiment has the characteristics of easy operation and good use experience, so that the home environment is more comfortable and intelligent.
The step of acquiring the noise reduction information corresponding to the noise combination may be performed in a variety of ways, and the following steps are performed sequentially.
Specifically, the method comprises the following steps:
acquiring combined noise information corresponding to the noise combination;
and calculating noise reduction information corresponding to the noise combination according to the combined noise information.
After the combined noise information corresponding to the noise combination is obtained, the combined noise information is calculated, and noise reduction information is obtained.
Further, the step of "calculating noise reduction information corresponding to the noise combination according to the combined noise information" includes:
the phase information of the combined noise information is converted into the opposite phase information which is 180 degrees different, the opposite phase information is set as the noise reduction information, and the noise reduction information is different from the combined noise information in that the amplitudes of sound waves at the same time point are equal and the phases are opposite, and the combined noise information and the noise reduction information are mutually offset after being overlapped.
Further, the acquisition of the combined noise information corresponding to the noise combination may be performed in a plurality of modes as described below.
Example 1
The method comprises the following steps:
recording combined noise information for each noise combination in the kitchen;
according to the combined noise information, noise reduction information corresponding to each noise combination is calculated;
and inquiring the noise reduction information corresponding to each noise combination.
N noise devices in kitchen, when at least one device is in working state, the total number of arrangement combinations which can be formed isNamely 2 composed of any one device in n devices, any two devices … …, any n-1 devices and all devices n -1 kind of combination, obtaining the combined noise information of each combination, and processing the corresponding 2 according to the combined noise information n -1 noise reduction information, when noise reduction is required, at 2 n -querying corresponding noise reduction information from the 1 noise reduction information.
By acquiring the running states of n devices, it can be determined which combination mode is currently in, for example, the noise combination formed by the noise devices in the working states corresponding to the m devices in the working states is achieved by playing the noise reduction information of the combination, so that noise reduction is achieved.
The process can directly convert external sound signals into digital signals through the microphone, a user can finish the operation by himself, noise is emitted through running noise equipment, the microphone is used for monitoring, and the steps are repeated to obtain multiple groups of combined noise information.
Example 2
The method comprises the following steps:
recording unit noise information of each noise device in the kitchen in an independent working state;
according to the unit noise information, calculating combined noise information corresponding to the noise combination of each noise device in the kitchen;
and calculating noise reduction information corresponding to each noise combination according to the combined noise information.
When there are too many devices in the kitchen, and it is inconvenient for the user to record all the combined noise information of all the devices in advance, this embodiment introduces a simplified processing scheme, by acquiring the unit noise information of each noise device, and by acquiring the combined noise information of any number of devices in a calculation manner. For example, the unit noise information may be displayed in the form of a spectrum, and different unit noise information may be phase-superimposed at the same time, so that the spectrum of the combined sound may be plotted.
Still further, the step of "calculating combined noise information corresponding to the noise combination of each noise device in the kitchen based on the unit noise information" further includes:
recording background noise information of all noise equipment in a shutdown state;
and calculating combined noise information corresponding to the noise combination of each noise device in the kitchen according to the unit noise information and the background noise information.
Since each device contains approximately the same background noise when individually acquiring the unit noise information, in order to make the information processing from the noise of a single device to the combined noise of a plurality of devices more accurate, the step of acquiring the background noise information is further included, so that the same background noise part is prevented from being repeatedly calculated, thereby further improving the accuracy of the calculated noise reduction information.
Example 3
The method also comprises the steps of:
acquiring equipment information of each noise equipment;
acquiring equipment noise information of each noise equipment from a server according to the equipment information;
acquiring background noise information of all noise equipment in a shutdown state;
and calculating combined noise information corresponding to the noise combination of each noise device in the kitchen according to the device noise information and the background noise information.
Generally, the noise generated by the appliances of the same model during normal operation is approximately the same, and in order to simplify the step of inputting the noise sampling by a user, the corresponding equipment is selected in the record only by acquiring the information of the equipment of the appliances from the server side or storing the equipment noise information corresponding to some equipment in advance. The difference between the device noise information and the unit noise information is that the unit noise information is recorded in the environment of the kitchen, the unit noise information comprises the background noise of the environment, the device noise information is the inherent noise corresponding to the current device and does not contain the background noise information of the kitchen of the user, so that the background noise information of the local kitchen is fused again in the process of processing the device noise information into the local combined noise information, and the calculated combined noise information is more consistent with the use environment of the local kitchen.
Further, the step of "acquiring the noise combination of the noise device in the kitchen in the operating state" includes:
detecting the state of a switch of noise equipment in a kitchen;
a noise combination of a noise device with a switch in an on state is obtained.
The socket panel can be used for detecting the state of the switch or detecting the change of the current or judging the change of the current, or the electrical equipment is provided with a networking module, and when the electrical equipment is opened and operated, the state information of the switch is uploaded, and the switch is opened, namely the corresponding equipment is in the working state.
Further, the method further comprises the steps of:
when at least one noise device is changed from the stop state to the working state and/or at least one noise device is changed from the working state to the stop state, the noise reduction sound wave is turned off;
acquiring a new noise combination of the noise equipment in the working state again;
acquiring new noise reduction information corresponding to the new noise combination;
and sending out corresponding noise reduction sound waves according to the new noise reduction information.
When the original noise equipment in operation stops working or starts working by new noise equipment, the noise reduction information corresponding to the original noise combination is inapplicable, the noise combination information is updated at the moment, the combination of the noise equipment in the new working state is marked as a new noise combination, and the noise reduction method is used for noise reduction of the new noise combination.
In addition, the noise equipment comprises one or more of a range hood, a microwave oven, an oven, a dish washer, an electromagnetic oven, a juicer, an electric kettle, an electric cooker, a garbage disposer and an air fryer, and a user can set more noise equipment according to the requirements.
Generally, the kitchen has the largest noise and the longest working time, and the range hood can distinguish the noise sent by different working gears, for example, the noise is large when the suction force is large, and conversely, the noise is small when the wind speed is small, and part of the range hood can change the wind speed in real time even according to the condition of the oil smoke. The embodiment also comprises a noise reduction method for the range hood at various wind speeds, and specifically comprises the following steps:
if the noise equipment in the working state comprises a range hood, acquiring a wind speed interval of the range hood;
and marking the noise combination as noise equipment except the range hood in the wind speed range.
According to the embodiment, the noise emitted by the range hood is distinguished according to the wind speed range of the range hood, the noise is regarded as the same noise in the same range, the noise corresponding to each range is summarized with other equipment, a new noise combination aiming at the wind speed of the range hood and the other equipment is obtained, and noise reduction is carried out on the noise combination according to the above.
In addition, q wind speed intervals of the range hood and other n-1 devices except the range hood can form 2 n+q-1 Seed arrangement combinations, obtain 2 n+q-1 And the noise information of each combination in the noise combinations is acquired, so that when the wind speed interval in which the wind speed is located is determined, noise reduction sound waves corresponding to the wind speed interval and the noise reduction information of m-1 devices are emitted by combining other noise devices in working states, and noise reduction is realized.
