Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The present invention provides a method for controlling an air conditioner, and referring to fig. 1, in an embodiment, the method for controlling an air conditioner includes:
step S10, when the air conditioner runs, obtaining indoor sound information and indoor light intensity value;
specifically, after the air conditioner is started, indoor sound information and an indoor light intensity value are automatically acquired. It should be noted that the obtaining of the indoor sound information and the indoor light intensity value may be triggered by the starting of the air conditioner, or may be triggered by a specific instruction, for example, may be triggered by a key instruction of a remote controller; or may be triggered when the current time reaches a particular clock time.
In a preferred embodiment of the present invention, when the air conditioner is operated, the indoor sound information and the indoor light intensity value are automatically acquired at regular intervals of a preset time period. The preset time interval can be preset time length preset by a user according to the use condition of the user, or the preset time length calculated by the air conditioner according to the use habit of the user can be prestored in the air conditioner system. In a preferred embodiment of the present invention, the predetermined time interval is 20 minutes; that is, when the air conditioner starts to operate, the indoor sound information is automatically acquired every 20 minutes.
Step S20, comparing the obtained indoor light intensity value with an indoor standard light intensity value;
in particular, the indoor light intensity value may be obtained in various ways. For example, an indoor light intensity signal may be obtained by using a light intensity sensor, the light intensity sensor includes a light intensity sensing module, a signal conversion circuit, and a signal comparison module, the light intensity sensing module is configured to obtain indoor light intensity and output the obtained indoor light intensity to the signal conversion circuit, the signal conversion circuit converts indoor light intensity into a corresponding indoor light intensity value voltage signal and outputs the indoor light intensity value voltage signal to the signal comparison module, and the signal comparison module is configured to provide an indoor standard light intensity value voltage signal and compare the indoor light intensity value voltage signal output by the signal conversion circuit to determine whether the indoor light intensity value is less than or equal to the indoor standard light intensity value.
It should be noted that, in a preferred embodiment of this embodiment, the indoor standard light intensity value is 10lx, and when the indoor light intensity value is less than or equal to 10lx, it indicates that the indoor light is dark, which is suitable for a person to sleep or enter sleep, for example, when the light is not turned on at night or when the light is not turned on during the day.
Step S30, when the indoor light intensity value is less than or equal to the indoor standard light intensity value, judging whether the indoor is in a quiet state according to the acquired indoor sound information;
in the present embodiment, the following two embodiments will be described. For example, in one embodiment of the present invention, the acquired indoor sound information may be compared and identified. It can be understood that when the user is indoors, there is necessarily a respiratory sound or a snoring sound or a speaking sound; when the air conditioner is started, the air conditioner can also make sound of equipment operation, so that the obtained indoor sound information needs to be identified and judged; that is, it is necessary to determine which of the acquired audio information is human audio information and which is audio information for operating the apparatus. When the acquired voice information is judged to have the voice information of the person, whether the acquired voice information of the person is snore or slight breath sound needs to be further judged, and if the acquired voice information of the person is not the snore or the slight breath sound of the person, the indoor environment is not in a quiet state at the moment.
In another embodiment of the present invention, the sound level of the acquired room sound information may be determined. For example, a sound level threshold may be preset, and when the acquired indoor sound information is less than or equal to the preset threshold, it indicates that the room is in a quiet state.
And step S40, controlling the air conditioner to operate in the sleep mode when the indoor is in the quiet state.
It will be appreciated that the sleep mode may be an operation in which the air conditioner may cool or heat relatively quietly, and generally, the cooling or heating may be quieter in the sleep mode than in the normal cooling or heating mode of the air conditioner. For example, it can be realized by appropriately reducing the operating frequency of the air conditioner, reducing the air output, reducing the air blowing angle, and the like.
In the technical scheme of the invention, when the air conditioner runs, indoor sound information and an indoor light intensity value are obtained; comparing the obtained indoor light intensity value with an indoor standard light intensity value; when the indoor light intensity value is smaller than or equal to the indoor standard light intensity value, judging whether the room is in a quiet state or not according to the acquired indoor sound information; and when the indoor is in a quiet state, controlling the air conditioner to operate in a sleep mode. Whether the indoor sound information meets the condition of sleeping of the person or not is further judged by judging under the condition that the indoor light intensity value meets the condition of sleeping of the person, and when the indoor light intensity value and the indoor sound information meet the requirement at the same time, the air conditioner is automatically controlled to run in a sleeping mode, so that a user is not required to manually set the indoor sound information to enter the sleeping mode, the convenience and the intellectualization of air conditioner control are improved, and the user experience is improved.
Further, referring to fig. 2, based on the foregoing embodiment, in this embodiment, the step S30 further includes:
step S311, when the indoor light intensity value is less than or equal to the indoor standard light intensity value, comparing and identifying the acquired indoor sound information with prestored sound information, and judging whether the sound information of a person exists in the indoor sound information;
in step S312, when it is determined that the voice information of the person does not exist in the indoor voice information, it is determined that the room is in a quiet state.
The air conditioner may collect sound information of the room in advance, for example, sound information of a person, sound information of an operation of the equipment, sound information of music or video playing, and the like, and may memorize and store different sound information.
Specifically, when it is determined that the indoor light intensity value is less than or equal to the indoor standard light intensity value, the acquired indoor sound information is compared with pre-stored sound information for identification, that is, the acquired indoor sound information is compared with a plurality of pre-stored sound information of different types, and whether the acquired indoor sound information contains human sound information is identified through a certain operation method. When the voice information of the person does not exist in the acquired indoor voice information, the user is judged to be in a quiet state at the current moment when the user enters the sleep.
In the embodiment, an implementation step of judging whether the room is in a quiet state according to the sound information of people in the room is further provided; that is, the obtained indoor sound information is compared with the pre-stored sound information for identification, and when the sound information of a person does not exist in the indoor sound information, the indoor sound information is judged to be in a quiet state; the air conditioner can automatically judge whether the indoor space is in a quiet state or not by the mode, and the intellectualization of the air conditioner is improved.
Further, referring to fig. 3, based on the foregoing embodiment, in this embodiment, the step S30 further includes:
step S321, when the indoor light intensity value is less than or equal to the indoor standard light intensity value, converting the obtained indoor sound information into an indoor noise value or an indoor noise energy value;
in step S322, when the indoor noise value is less than or equal to the indoor standard noise value, or the indoor noise energy value is less than or equal to the indoor standard noise energy value, it is determined that the room is in a quiet state.
Specifically, in this embodiment, the indoor sound information is obtained through the microphone, and the microphone is provided with a radio system, a conversion circuit and a microprocessor, and the radio system collects the indoor sound information and transmits the indoor sound information to the conversion circuit.
It can be understood that, the microphone presets and stores an indoor standard noise value or an indoor standard noise energy value, and then compares the indoor noise value converted from the obtained indoor sound information with the indoor standard noise value, or compares the converted indoor noise energy value with the indoor standard noise energy value; and when the indoor noise value is smaller than or equal to the indoor standard noise value or the indoor noise energy value is smaller than or equal to the indoor standard noise energy value, judging that the current indoor is in a quiet state.
It should be noted that, in this embodiment, the indoor standard noise value is 40dB, and the indoor standard noise energy value is 10-8W; that is, when the indoor noise energy value is less than or equal to 40dB or the indoor noise energy value is less than or equal to 10- 8And W, judging that the current indoor is in a quiet state.
In this embodiment, on the premise that the indoor light intensity value is less than or equal to the indoor standard light intensity value, a specific implementation step of obtaining indoor sound information by setting a microphone is further provided, the obtained indoor sound information is converted into an indoor noise value or an indoor noise energy value, and the indoor noise value or the indoor noise energy value is compared with the indoor standard noise value or the indoor standard noise energy value to determine whether the indoor environment is quiet, so that the control method of the air conditioner is more convenient and intelligent.
Further, referring to fig. 4, based on the above embodiment, in this embodiment, the method for controlling an air conditioner includes:
step S10, when the air conditioner runs, obtaining indoor sound information and indoor light intensity value;
step S20, comparing the obtained indoor light intensity value with the indoor standard light intensity value, and determining whether the indoor light intensity value is less than or equal to the indoor standard light intensity value; if yes, go to step S30;

step S40, when the room is in quiet state, controlling the air conditioner to operate in sleep mode;
in step S50, when the indoor light intensity value is judged to be greater than the indoor standard light intensity value, the indoor sound information and the indoor light intensity value are obtained again.
It can be understood that when the indoor light intensity value is greater than the indoor standard light intensity value, it indicates that the indoor light condition is not suitable for sleeping at that time, for example, in the daytime or in the case of turning on the light indoors, it can be automatically determined that the current environment does not conform to the sleeping environment of the person, and then the indoor sound information and the indoor light intensity value are obtained again. And then sequentially judging whether the indoor light intensity value and the indoor sound information which are acquired again meet the condition for controlling the air conditioner to operate in the sleep mode or not, and controlling the air conditioner to operate in the sleep mode when the indoor light intensity value is smaller than or equal to the indoor standard light intensity value and the indoor is in the quiet state.
In this embodiment, implementation steps of the control method of the air conditioner are further provided when the indoor light intensity value is greater than the indoor standard light intensity value, so that the control method of the air conditioner is perfected.
Further, referring to fig. 5, based on the above embodiment, in this embodiment, the method for controlling an air conditioner includes:
step S10, when the air conditioner runs, obtaining indoor sound information and indoor light intensity value;
step S20, comparing the obtained indoor light intensity value with the indoor standard light intensity value, and determining whether the indoor light intensity value is less than or equal to the indoor standard light intensity value; if yes, go to step S30;
step S30, judging whether the room is in a quiet state according to the acquired indoor sound information; if yes, go to step S40;

step S50, when the indoor light intensity value is judged to be larger than the indoor standard light intensity value, the indoor sound information and the indoor light intensity value are obtained again;
and step S60, when the indoor is judged not to be in a quiet state according to the acquired indoor sound information, the indoor sound information and the indoor light intensity value are acquired again.
Specifically, in one embodiment, when it is determined that human voice information is present in the indoor voice information, that is, when the condition for the air conditioner to operate in the sleep mode is not satisfied, the indoor voice information and the indoor light intensity value are newly acquired.
In another embodiment, when the indoor noise value is greater than the indoor standard noise value, or when the indoor noise energy value is greater than the indoor standard noise energy value, it can be considered that the current indoor environment state does not conform to the sleep environment of the person, and then the indoor sound information and the indoor light intensity value are acquired again. And then sequentially judging whether the indoor light intensity value and the indoor sound information which are acquired again meet the condition for controlling the air conditioner to operate in the sleep mode or not, and controlling the air conditioner to operate in the sleep mode when the indoor light intensity value is smaller than or equal to the indoor standard light intensity value and the indoor is in the quiet state.
In this embodiment, a specific implementation step of reacquiring the indoor sound information and the indoor light intensity value when it is determined that the room is not in a quiet state is further provided; that is to say, when the indoor sound information does not satisfy the condition that the air conditioner operates in the sleep mode, the control method of the air conditioner can obtain the indoor sound information and the indoor light intensity value until the condition that the air conditioner operates in the sleep mode is satisfied, the control method of the air conditioner is perfected, the user does not need to manually set the indoor sound information and enter the sleep mode, and the user experience is improved.
