Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following will explain the air conditioner control method and apparatus in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In one embodiment, as shown in fig. 1, there is provided an air conditioner control method including the steps of:
and S102, acquiring noise information of the environment where the air conditioner indoor unit is located.
The environment in which the air conditioner indoor unit is located refers to the noise collection environment in step S102. The air conditioner indoor unit is installed indoors, and can be in each room of a household or in a public environment. For example, when the air conditioner indoor unit is installed in a living room of a home or a conference room of a company, the environment where the air conditioner indoor unit is located is the living room or the conference room. The noise information refers to an electric signal that is an environmental noise collected by the noise collecting means and converts the noise into. The environmental noise includes all noises in the environment where the air conditioner indoor unit is located, such as the voice of human speaking, the noise generated by human activity, etc. The noise generated by human body activity refers to the sound emitted by a human in the environment of the air conditioner internal unit, such as the sound of stomping a foot, the sound of rubbing a hand, the sound of rubbing an object and the sound emitted by the human subconscious. Conventional noise collection devices may be used in embodiments of the present invention.
And S104, carrying out audio analysis on the noise information to obtain the audio characteristics of the human body activity noise information in the noise information.
And audio analysis can be performed by using an audio analyzer. The method comprises the steps of filtering noise information and filtering non-human body activity noise information. After audio analysis, the audio characteristics of the human activity noise information in the noise information are obtained.
And S106, determining the human body activity according to the audio features.
The human activity refers to the activity of people in the environment space where the indoor unit of the air conditioner is located. The human activity can reflect the comfort level of the human feeling the temperature in the environment. The human voice frequency is generally concentrated on medium-high frequency, and the noise generated during human activity is generally in low frequency range, so that the human activity can be judged. The sound generated by human body activity and moving objects is mostly low-frequency noise (20HZ-390HZ), for example, when the audio characteristic noise suddenly increases or oscillates in a low frequency band, the human body activity can be judged to be high. If the audio frequency characteristics are stable in the low frequency band, the human body activity can be judged to be low.
And S108, adjusting the working power of the air conditioner according to the activity of the human body.
The adjustment of the working power of the air conditioner can be realized by adjusting the blowing speed of the air conditioner or adjusting the working power of the compressor of the air conditioner. The method for adjusting the working power of the air conditioner can be various, for example, the working power of the air conditioner can be properly increased or decreased when the activity of the human body is high. When the activity of human body is low, the working power of air conditioner is kept.
According to the air conditioner control method provided by the embodiment of the invention, the audio frequency characteristics of the human activity noise information in the noise information are obtained by analyzing the noise information of the environment where the air conditioner indoor unit is located. The human body activity noise is not instruction information sent by the user, but noise sent by the user in an unnatural or subconscious environment. For example, the user may make a sound by the action of a hand fan when feeling that the room is overheated. The method also determines the human body activity according to the audio frequency characteristics, and then adjusts the working power of the air conditioner according to the human body activity. The human activity reflects the comfort level of the human body. Therefore, the user does not need to send an instruction to drive the adjustment of the working power of the air conditioner, the air conditioner actively feels the comfort level of the user, and then the working power of the air conditioner is automatically adjusted. The automatic control of the air conditioner temperature regulation is realized, and the air conditioner control efficiency is improved.
In one embodiment, the human activity noise information is noise information of a low frequency band in the noise information; the audio characteristics include human activity noise intensity and/or frequency. In the human activity noise, the voice of a human speaking is a high frequency voice, and the voice of a human activity or a moving object is a low frequency voice. In this embodiment, the human activity noise information is noise information of a low frequency band in the noise information. The automatic control of the air conditioner can be realized by selecting the sound of human activities or moving objects, the user does not need to send instructions, and the air conditioner can actively adjust the indoor temperature, so that the intelligent air conditioner is more intelligent.
Referring to fig. 2, in an embodiment, before the step of adjusting the operating power of the air conditioner according to the human activity, the air conditioner control method further includes a step of determining whether the human activity matches a preset human activity. The step of judging whether the human body activity is matched with the preset human body activity specifically comprises the following steps:
s202, comparing the human body activity with a preset human body activity.
The preset human body activity corresponds to a preset environmental noise message. The preset ambient noise information may be noise information of the noise information when the noise information does not include human activity noise information. That is, in the environment where the air conditioner indoor unit is located, there is no human body movement noise, but only noise that exists naturally. There may be no sound emitted by a human body in the environment, or there may be no human being present in the environment. The preset environmental noise information can be used as a reference value of noise, and the comparison of the human body activity and the preset human body activity can be realized by comparing the audio frequency characteristics of the human body activity noise information with the audio frequency characteristics of the preset environmental noise information.
And S204, when the human body activity is matched with the preset human body activity, returning to the step of acquiring the noise information of the environment where the air conditioner indoor unit is located.
If the audio frequency characteristics of the preset environmental noise information are consistent with the audio frequency characteristics of the human activity noise information, the matching of the human activity and the preset human activity can be judged. Therefore, the working power of the air conditioner does not need to be adjusted in the current environment of the air conditioner indoor unit, and the step of obtaining the noise information of the environment of the air conditioner indoor unit is returned to be executed.
S206, when the human body activity is not matched with the preset human body activity, executing the step of adjusting the working power of the air conditioner according to the human body activity.
If the audio frequency characteristics of the preset environmental noise information are inconsistent with the audio frequency characteristics of the human activity noise information, the human activity degree can be judged to be not matched with the preset human activity degree. At this time, the air conditioner operation power is adjusted.
In this embodiment, the step of adjusting the working power of the air conditioner according to the human activity is controlled and executed by judging whether the human activity matches the preset human activity. And returning to the step of acquiring the noise information of the environment where the air conditioner indoor unit is located when the human body activity is matched with the preset human body activity. The air conditioner control method can be continuously carried out, the noise in the environment is continuously monitored, when the audio characteristics of the preset environment noise information are inconsistent with the audio characteristics of the human activity noise information, the working power of the air conditioner is adjusted, the continuous real-time monitoring on the environment comfort level is realized, and the air conditioner control method is more intelligent.
In one embodiment, step S108 further comprises the steps of: judging the working state of the air conditioner; if the working state of the air conditioner is refrigeration, the working power of the air conditioner is improved; and if the working state of the air conditioner is heating, reducing the working power of the air conditioner.
In this embodiment, the working state of the air conditioner is cooling or heating. When in a refrigerating state, the discomfort of a human body is caused by high ambient temperature, the air conditioner is adjusted towards the direction of reducing the indoor temperature, the wind power can be increased or the working power of the compressor can be enhanced, and therefore, the adjustment direction is to improve the working power of the air conditioner. In the heating state, the discomfort of human body is generated when the environment temperature is high, so the air conditioner is adjusted to the direction of reducing the indoor temperature, the wind power can be reduced or the working power of the compressor can be reduced, and the adjustment direction is to reduce the working power of the air conditioner. Through the specific adjustment mode of setting the working power of the air conditioner, the working efficiency is further improved.
In one embodiment, before performing the audio analysis on the noise information, the air conditioning control method further includes the steps of: judging the position of the human body according to the noise information; the air outlet direction of the air conditioner indoor unit is adjusted according to the position of the human body, so that the air outlet direction faces the position of the human body. In this embodiment, realized automatic judgement human position, then automatic adjustment air-out direction for the air conditioner air-out is automatic towards the human body, has further improved the work efficiency of air conditioner.
Referring to fig. 3, in an embodiment, before performing the audio analysis on the noise information, the air conditioning control method further includes a step of comparing the indoor temperature with a preset temperature, wherein the step of comparing the indoor temperature with the preset temperature includes the steps of:
s302, acquiring indoor temperature;
s304, if the difference value between the indoor temperature and the preset temperature is less than or equal to the preset temperature difference, performing audio analysis on the noise information;
and S306, if the difference value between the indoor temperature and the preset temperature is larger than the preset temperature difference, adjusting the working power of the air conditioner towards the direction that the difference value is close to the preset temperature difference.
The indoor temperature refers to the temperature of the environment where the air conditioner indoor unit is located. The indoor temperature can be obtained in various ways, for example, directly by a temperature sensor disposed in the environment. The preset temperature is a preset temperature of the air conditioner, which is preset by a user before the air conditioner is turned on. It is understood that the range of the preset temperature difference can be selected according to the requirement, and for example, the range can be plus or minus 1 degree, or plus or minus 0.5 degree. The difference value between the indoor temperature and the preset temperature is smaller than or equal to the preset temperature difference, which means that the difference value is within the range of the preset temperature difference. The difference between the indoor temperature and the preset temperature being greater than the preset temperature difference means that the difference is outside the range of the preset temperature difference. The adjusting of the air conditioner operating power in the direction in which the difference value approaches the preset temperature difference means that the difference value is made to approach the preset temperature difference by adjusting the air conditioner operating power. For example, when the indoor temperature is higher than the preset temperature and the air conditioning power needs to be adjusted. If the air conditioner is in a refrigerating state, the power of the air conditioner needs to be increased to enhance refrigeration; if the heating state is in the heating state, the air conditioner power needs to be reduced, and the heating is weakened. The scheme provided by the embodiment adjusts the working power of the air conditioner according to the indoor temperature and the preset temperature. And under the condition that the indoor temperature is close to the preset temperature, carrying out audio analysis on the noise information, and judging whether the air conditioner power needs to be further adjusted or not, so that the accuracy of air conditioner control is further improved.
Referring to fig. 4, in one embodiment, S302 includes the following steps:
s402, acquiring an indoor temperature gradient of an air conditioner internal unit body along the gravity direction, wherein the indoor temperature gradient is acquired by a plurality of first temperature sensors which are arranged on the air conditioner internal unit body and are sequentially arranged along the gravity direction;
s404, judging whether a first indoor temperature measured by a second temperature sensor arranged on the air conditioner remote controller is obtained;
s406, if yes, calculating the indoor temperature according to the indoor temperature gradient and the first indoor temperature;
and S408, if not, carrying out weighted average according to the indoor temperature gradient to obtain the indoor temperature.
The calculation of the indoor temperature from the indoor temperature gradient and the first indoor temperature may be performed in various ways. For example, one may average through the room temperature gradient and then average the first room temperature by the average. In this embodiment, the indoor temperature gradient along the direction of gravity of the internal unit body of the air conditioner and the first indoor temperature measured by the second temperature sensor on the remote controller of the air conditioner are used. Under the condition that the first indoor temperature cannot be obtained, the indoor temperature gradient can be directly weighted and averaged to obtain the indoor temperature, and the problem that the air conditioner control method cannot be executed due to the fact that the indoor temperature cannot be obtained when the air conditioner remote controller is powered off or lost is avoided.
Referring to fig. 5, in an embodiment, the step S406 specifically includes the following steps:
s502, judging whether the change rate of the temperature gradient in the chamber is zero within the preset time;
s504, if the change rate is not zero, obtaining the indoor temperature according to the first indoor temperature;
s506, if the change rate is zero, calculating the average temperature according to the indoor temperature gradient;
s508, judging whether the temperature difference value between the average temperature and the first indoor temperature is smaller than a preset temperature difference value or not;
s512, if the temperature difference value is smaller than or equal to the preset temperature difference value, taking any one of the first indoor temperature and the average temperature as the indoor temperature;
and S514, if the temperature difference value is larger than the preset temperature difference value, taking the first indoor temperature as the indoor temperature.
The preset time can be set as required. And if the change rate of the temperature gradient in the room within the preset time is zero, the temperature near the body of the indoor unit of the air conditioner is stable. Therefore, the indoor temperature can be calculated through the average temperature and the first indoor temperature, and the accuracy of the calculation result is improved. And if the change rate of the temperature gradient in the room within the preset time is not zero, the temperature near the body of the indoor unit of the air conditioner is unstable. At this time, the accuracy of the result can be ensured by taking the first indoor temperature as the indoor temperature. According to the technical scheme, the accuracy of the indoor temperature is further improved, and therefore the accuracy of the adjustment of the working power of the air conditioner according to the indoor temperature is improved.

a human activity confirmation module 606, configured to determine human activity according to the audio features;
and the power adjusting module 608 is used for adjusting the working power of the air conditioner according to the activity of the human body.
