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, indoor sound information is acquired according to a preset time interval;
specifically, after the air conditioner is started, indoor sound information is automatically acquired at regular intervals of preset duration. 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.
The route of acquiring the room audio information is not limited to one method. For example, in a preferred embodiment of the present invention, the air conditioner acquires the indoor sound information through a microphone provided. The microphone is provided with a sound receiving system, so that sound information in a preset range can be effectively acquired, converted into circuit signals and transmitted to a control system of the air conditioner.
Step S20, judging whether the room 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 S30, controlling the air conditioner to operate in a sleep mode when the indoor is judged to be in a quiet state and the current time reaches a preset time threshold.
Specifically, judging that the current indoor environment is in a quiet state according to the acquired indoor sound information, judging whether the current clock time reaches a preset time threshold value, and controlling the air conditioner to operate in a sleep mode if the current clock time reaches the preset time threshold value.
It should be noted that the preset time threshold may be a time threshold preset by a user, or may be a time threshold calculated by the air conditioner according to daily setting parameters and sleeping habits of the user. In a preferred embodiment of the present invention, the time threshold is later than 23 o ' clock and earlier than 7 o ' clock, that is, when it is judged that the room is in a quiet state according to the acquired room sound information and the current time is 23 o ' clock or 23 o ' clock and is not more than 7 o ' clock in the morning, the air conditioner is controlled to operate the sleep mode.
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 is acquired according to a preset time interval; judging whether the room is in a quiet state or not according to the acquired indoor sound information; and controlling the air conditioner to operate in a sleep mode when the indoor is in a quiet state and the current time reaches a preset time threshold. The air conditioner is automatically controlled to operate in the sleep mode by judging the condition of meeting the requirement of entering the sleep mode, the user is not required to manually set the sleep mode, the convenience and the intelligence of air conditioner control are improved, and the user experience is improved.

step S211, comparing and identifying the acquired indoor sound information with prestored sound information, and judging whether human sound information exists in the indoor sound information;
in step S212, when it is determined that the voice information of the person is not present in the indoor voice information, it is determined that the room is in a quiet state.
The air conditioner may collect sound information of a room in advance, and memorize and store the collected sound information of different types, for example, may collect sound information of a person, sound information of equipment operation, sound information of music or video playback, and the like in advance, and memorize and store different sound information.
Specifically, when the air conditioner is started to operate, indoor sound information is acquired according to a preset time interval, the acquired indoor sound information is compared with prestored sound information for identification, that is, the acquired indoor sound information is compared with prestored sound information of a plurality of different categories, and whether human sound information exists in the acquired indoor 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 S20 further includes:
step S221, converting the obtained indoor sound information into an indoor noise value or an indoor noise energy value;
in step S222, 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 level is less than 40dB, or the indoor noise energy level is less than 10-8And W, judging that the current indoor is in a quiet state.
In this embodiment, a specific implementation step of acquiring indoor sound information by setting a microphone is further provided, and the acquired indoor sound information is converted into an indoor noise value or an indoor noise energy value, and compared with an indoor standard noise value or an 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, indoor sound information is acquired according to a preset time interval;
step S20, judging whether the room is in a quiet state according to the acquired indoor sound information;
step S40, when the indoor is judged to be in the quiet state, judging whether the continuous time of the indoor in the quiet state is more than the preset time;
and step S50, controlling the air conditioner to operate in the sleep mode when the continuous time of the indoor quiet state is judged to be greater than the preset time and the current time reaches the preset time threshold.
It should be noted that, for the specific implementation of the steps S10 and S20, reference may be made to the above embodiments, which are not repeated herein.
It is to be understood that, when the quiet state of the room is determined, it is further determined whether the time of the quiet state of the room is greater than a preset time. In this embodiment, the preset time is 10 minutes. For example, comparing and identifying the acquired indoor sound information with prestored sound information, judging that the sound information of people does not exist in the indoor sound information, and controlling the air conditioner to operate in a sleep mode when the continuous time of the sound information of people which does not exist in the room is longer than 10 minutes and the current time also reaches a preset time threshold; or when the continuous time that the indoor noise value is smaller than or equal to the indoor standard noise value is longer than 10 minutes, or the continuous time that the indoor noise energy value is smaller than or equal to the indoor standard noise energy value is longer than 10 minutes, and the current time reaches a preset time threshold value, controlling the air conditioner to operate in a sleep mode.
In the technical solution provided in this embodiment, it is further defined whether the indoor continuous time in the quiet state is greater than the preset time, and the current time reaches the preset time threshold, and when both of the above two conditions are satisfied, the air conditioner is controlled to operate in the sleep mode. The condition whether the air conditioner is controlled to operate in the sleep mode is further refined, so that the control method of the air conditioner is more accurate and humanized.
