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:
s102, obtaining an indoor temperature gradient of the air conditioner internal unit body along the gravity direction, wherein the indoor temperature gradient is obtained 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.
The air conditioner indoor unit is an air conditioner indoor unit which is installed indoors and used for air outlet. Including but not limited to on-hook mounted on an indoor wall, a stand-type cabinet air conditioner, and a window machine. The indoor temperature gradient refers to a change value of temperature per unit length. The indoor temperature gradient of the air conditioner indoor unit body along the gravity direction refers to the temperature gradient of the air conditioner indoor unit in the vertical direction. Specifically, the temperature value can be calculated by arranging a plurality of first temperature sensors on the body of the air conditioner indoor unit along the direction of gravity and measuring the temperature value at the corresponding height. It can be understood that the number of the plurality of first temperature sensors is not limited, and the first temperature sensors can be arranged according to the volume of the air conditioner indoor unit and the actual requirement, and the more the number of the first temperature sensors, the more accurate the obtained result.
And S104, acquiring the temperature of the remote controller end measured by a second temperature sensor arranged on the air conditioner remote controller.
The temperature of the remote controller end is measured by a second temperature sensor arranged on the air conditioner remote controller. Usually, when a user uses the air conditioner remote controller, the air conditioner remote controller is placed at a position relatively close to a human body. Therefore, the remote controller end temperature measured on the air conditioner remote controller is the temperature of the indoor space at a position relatively close to the human body.
And S106, calculating the indoor temperature according to the indoor temperature gradient and the temperature of the remote controller end.
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. When the temperature of the remote controller end is obtained, the indoor temperature can be calculated according to the indoor temperature gradient and the temperature of the remote controller end. The indoor temperature can be calculated according to the indoor temperature gradient and the temperature of the remote controller end, and the calculation can be realized in various ways. For example, the temperature gradient in the room can be averaged, and then the average value is averaged with the temperature at the remote controller.
And S108, if the difference value between the indoor temperature and the preset temperature is out of the preset temperature difference range, adjusting the working power of the air conditioner towards the direction that the indoor temperature approaches the preset temperature.
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 preset temperature difference range can be selected according to the requirement, and can be, for example, plus or minus 1 degree, or plus or minus 0.5 degree. For example, if the difference between the indoor temperature and the preset temperature is 0.5 when the preset temperature difference is in the range of-1 to +1, the difference between the indoor temperature and the preset temperature is in the preset temperature difference range. If the difference between the indoor temperature and the preset temperature is 1.5, the difference between the indoor temperature and the preset temperature is outside the preset temperature difference range. The adjusting of the air conditioner operating power in the direction in which the indoor temperature approaches the preset temperature 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.
In this embodiment, when the temperature of the remote controller end measured by the second temperature sensor on the air conditioner remote controller is obtained, the indoor temperature is calculated according to the indoor temperature gradient of the internal unit body of the air conditioner along the gravity direction and the temperature of the remote controller end. The accuracy of indoor temperature calculation can be guaranteed. And then according to the relation between the difference value between the indoor temperature and the preset temperature difference, the working power of the air conditioner is adjusted towards the direction that the indoor temperature is close to the preset temperature, so that the air conditioner can automatically adjust the working power of the air conditioner according to the indoor temperature obtained by calculation and the preset temperature, and the control efficiency of the air conditioner is improved.
In one embodiment, after the step of acquiring the remote controller end temperature measured by the second temperature sensor provided on the remote controller of the air conditioner, the air conditioner control method in fig. 1 further includes the steps of: and if the temperature of the remote controller end fails to be obtained, carrying out weighted average according to the indoor temperature gradient to obtain the indoor temperature. According to the method, if the temperature of the remote controller end cannot be obtained, the indoor temperature gradient is used for carrying out weighted average according to the indoor temperature gradient to obtain the indoor temperature, so that 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 out of power or lost is solved.
Referring to fig. 2, in an embodiment, the step S106 of calculating the indoor temperature according to the indoor temperature gradient and the temperature of the remote controller end includes the following steps:
s202, acquiring the change rate of the indoor temperature gradient within preset time;
s204, when the change rate is within a preset near-zero range, calculating the average temperature according to the indoor temperature gradient;
s206, if the difference value between the average temperature and the temperature of the remote controller end is within a preset difference value range, taking any one of the temperature of the remote controller end and the average temperature as the indoor temperature;
and S208, if the difference value between the average temperature and the temperature of the remote controller end is out of a preset difference value range, taking the temperature of the remote controller end as the indoor temperature.
The preset time may be set as desired, such as 1 minute or 2 minutes. The preset near-zero range refers to a range including zero and close to zero, and can be set according to actual needs, such as-0.1 to +0.1, or-0.01 to + 0.01. The change rate of the indoor temperature gradient is zero, so that the temperature near the body of the indoor unit of the air conditioner is stable, and the stability degree of the temperature near the body of the indoor unit of the air conditioner can be judged according to the degree that the change rate of the indoor temperature gradient is close to zero in the preset time. And if the change rate of the temperature gradient in the room within the preset time is within a preset near-zero range, 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 temperature of the remote controller, and the accuracy of the calculation result is improved. The predetermined difference range is a predetermined range, such as-1 to +1, or may be set to 0. And if the difference value between the average temperature and the temperature at the remote controller end is within a preset difference value range, the average temperature is closer to the temperature at the remote controller end. If the difference value between the average temperature and the temperature of the remote controller end is out of the preset difference value range, the temperature near the air conditioner indoor unit is unstable, and the temperature of the remote controller end is directly used 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.
In one embodiment, after the step of obtaining the rate of change of the indoor temperature gradient within a preset time, the step of calculating the indoor temperature according to the indoor temperature gradient and the remote controller end temperature further includes: and when the change rate of the indoor temperature gradient is out of a preset near-zero range within a preset time, taking the temperature of the remote controller end as the indoor temperature. In this embodiment, if the change rate of the temperature gradient in the room within the preset time is outside the preset near-zero range, it indicates that the temperature near the body of the air conditioner internal unit is unstable. In this case, the temperature of the remote controller end can be used as the indoor temperature, so that the accuracy of the result is ensured.
Referring to fig. 3, in an embodiment, before the step of obtaining the indoor temperature gradient of the air conditioner internal unit body along the gravity direction, the air conditioner control method further includes a step of adjusting the direction of the air outlet of the air conditioner according to the noise information. The step of adjusting the direction of the air outlet of the air conditioner according to the noise information comprises the following steps:
and S302, acquiring noise information of the environment where the air conditioner indoor unit is located.
And S304, judging the position of the human body according to the noise information.
S306, adjusting the air outlet direction of the air conditioner indoor unit according to the human body position, so that the air outlet direction faces the human body position.
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 internal unit is installed in a living room of a home or a conference room of a company, the environment in which the air conditioner internal unit is located is the living room or the conference room. The environment in which the air conditioner indoor unit is located is the noise collection environment in step S302. 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. In this embodiment, the air conditioner control method realizes automatic judgment of the position of the human body, and then automatically adjusts the air outlet direction, so that the air outlet of the air conditioner automatically faces the human body, and the working efficiency of the air conditioner is further improved.
Referring to fig. 4, in an embodiment, the air conditioner control method further includes the steps of analyzing the noise information to obtain the activity of the human body and adjusting the operating power of the air conditioner. The steps of analyzing the noise information to obtain the human body activity and adjusting the working power of the air conditioner comprise the following steps:
s402, if the difference value between the indoor temperature and the preset temperature is within the preset temperature difference range, carrying out audio analysis on the noise information to obtain the audio characteristics of the human 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.
S404, 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.
S406, 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, if the difference value between the indoor temperature and the preset temperature is within the preset temperature difference range, the working power of the air conditioner is further adjusted according to the activity of the human body, so that the accuracy of air conditioner control is further improved. The method obtains the audio frequency characteristics of the human activity noise information in the noise information 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.
