[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0048] figure 1 It is a flow chart of the first embodiment of a control method provided by the embodiment of the present invention. In this embodiment, the control method is applied to a terminal, and the terminal may be an electronic device such as a smart phone, a tablet computer, a computer, or an e-book, or may be a wearable device such as a smart bracelet or a smart watch, or may be a Air conditioners, fans, air purifiers and other air treatment equipment. The terminal is provided with a camera or an infrared sensor, which can be used to acquire surrounding image information or sensing information. Various sensors are also arranged on the terminal for detecting the concentration of air. Wherein, the air includes at least one gas, such as oxygen, carbon dioxide, or other toxic gases. The control method includes the following steps S101-S104.

[0049] In step S101, the information of persons in the target area is acquired.

[0050] Specifically, firstly, the personnel information in the target area is acquired. In this implementation manner, the target area is located indoors, for example, it may be in a certain room. When it is detected that the terminal is located in the area, the terminal acquires personnel information in the target area. Among them, the way of obtaining personnel information may be to obtain surrounding image information through a camera, and identify whether there is a person in the image information; it may also be to obtain surrounding sensing information through an infrared sensor, and determine whether there is a person. The purpose of acquiring personnel information is to determine whether there are personnel in the target area, and if so, proceed to step S102.

[0051] In step S102, if the person information in the target area is that there is at least one person, air information in the target area is detected. Wherein, the air information includes concentration information of at least one gas.

[0052] Specifically, if it is determined that there is at least one person in the target area, the sensor of the terminal is turned on at this time to detect air information in the target area. Wherein, the air information includes concentration information of at least one gas. The gas may be oxygen, carbon dioxide, etc., or toxic gases such as carbon monoxide. The concentration information of the gas is obtained through the sensor for subsequent judgment.

[0053] In step S103, if the concentration information of the at least one gas exceeds a preset first concentration range, a first control instruction is generated according to the concentration information.

[0054]Specifically, if the concentration information of at least one gas exceeds the preset first concentration range, it indicates that the air quality is poor at this time, and at this time the first control instruction is generated according to the concentration information. Wherein, the density information exceeding the preset first density range includes: the density information is higher than the maximum value of the preset first density range or the density information is lower than the preset minimum value of the first density range. For example, the concentration information of carbon dioxide may be higher than the maximum value of the preset concentration range, or the concentration information of oxygen may be lower than the minimum value of the preset concentration range. When the concentration information of the gas exceeds the preset first concentration range, corresponding processing needs to be performed on the air in the target area at this time to ensure a normal living environment of the human body. Therefore, a first control instruction is generated. Wherein, the first control instruction is used to control corresponding equipment to perform air treatment operations.

[0055] In step S104, the first control instruction is sent to the target device, so as to control the target device to perform air treatment.

[0056] Specifically, the first control instruction is sent to a target device, where the target device includes an air conditioner, a fan, and an air cleaner. After receiving the first control instruction, the target device performs air treatment according to the control instruction. For example, the air conditioner can turn on the ventilation mode; the fan can be turned on to promote air flow; the air purifier can turn on the air purification, etc. It can be understood that the target device may also be other air processing devices, which is not limited in this embodiment.

[0057] As can be seen from the above, the control method in the embodiment of the present invention detects whether there is a person in the target area, detects the air information in the target area when there is a person, and controls the target device to perform air treatment when the air information is poor. On the one hand, it can automatically start the air treatment equipment when the air quality is poor, without the need for users to actively start it, which is more intelligent and convenient; on the other hand, it can be started only when there are people, saving energy consumption and improving user experience.

[0058] figure 2 It is a flow chart of the second embodiment of a control method provided by the embodiment of the present invention. The control method includes the following steps S201-S207. It can be understood that steps S201-S202 in this embodiment can also be applied to figure 1 In step S101 in the first embodiment shown, this embodiment is not limited thereto.

[0059] In step S201, image information in the target area is acquired through a camera or sensing information in the target area is acquired through an infrared sensor.

[0060] Specifically, in order to determine whether there is a person in the target area, the information in the target area may be acquired through a camera or an infrared sensor. In this implementation manner, there may be multiple ways of acquiring information according to different terminals. For example, if the terminal is a smart phone, wearable device, etc., the video information around the terminal can be obtained through the camera set on the terminal. Among them, the terminal can be equipped with cameras in multiple directions, so as to facilitate all-round image acquisition. Information; if the terminal is an air conditioner, air purifier and other equipment, the sensor information in the target area can be obtained through the infrared sensor set on the terminal, and the image information can also be obtained through the camera. It can be understood that, in other implementation manners, the camera or infrared sensor may also be set at a certain position in the target area, and the camera or infrared sensor may establish a wireless connection with the terminal. For example, if the target area is a room, then the camera or infrared sensor can be set at a certain position in the room. After the camera or infrared sensor acquires the image information or sensing information of the room, it will send the information to the terminal through wireless transmission. , and the terminal makes subsequent judgments.

[0061] In step S202, the image information or sensory information is identified, and whether there are human features in the image information or sensory information is judged.

[0062] Specifically, after the image information or sensing information is acquired, the information is identified to determine whether there are human features in the information. For example, when the acquired information is image information, by identifying the image information, it is judged whether there is an image feature conforming to the shape of the human body; when the acquired information is infrared sensing information, by identifying the sensing information, it is judged Whether there are regions that match the temperature signature of a human body. If it exists, it means that there is a person in the current area, and subsequent processing can be performed, and it enters step S203. If it does not exist, it enters step S201 again. It can be understood that the camera or infrared sensor can be set to start at regular intervals To obtain information, so as to save power consumption.

[0063] In step S203, air information in the target area is detected. Wherein, the air information includes concentration information of at least one gas.

[0064] Specifically, since there are people in the target area at this time, the gas sensor of the terminal is turned on at this time to detect air information in the target area. Wherein, the air information includes concentration information of at least one gas. The gas may be oxygen, carbon dioxide, etc., or toxic gases such as carbon monoxide. The concentration information of the gas is obtained through the sensor for subsequent judgment. It can be understood that, in other implementation manners, the gas sensor can also be set on other devices, or on the wall of the room, and be connected to the terminal through wireless, and after detecting the air information, the The air information is transmitted to the terminal wirelessly for analysis by the terminal.

[0065] In step S204, if the concentration information of the at least one gas exceeds a preset first concentration range, a first control instruction is generated according to the concentration information.

[0066] Specifically, it is judged whether the concentration information of the gas exceeds a preset first concentration range. Wherein, the concentration information of the at least one gas exceeding the preset first concentration range includes higher than the maximum value of the preset first concentration range or the concentration information is lower than the preset minimum value of the first concentration range. For example, for a gas necessary for the human body, such as oxygen, it is judged whether its content is lower than the minimum value of the preset concentration; for a gas that is harmful to the human body in excess, such as carbon dioxide, it is judged whether its content is higher than the maximum value of the preset concentration . When the concentration of at least one gas exceeds the preset range, a first control instruction will be generated.

[0067] In step S205, sending the first control instruction to the target device, so as to control the target device to perform air treatment.

[0068] In step S206, if the concentration information exceeds the preset second concentration range or the time for which the concentration information exceeds the preset first concentration range exceeds the preset first time threshold, generate Reminder command.

[0069] Specifically, when the gas concentration information exceeds the first concentration range, the air can be processed by the air treatment equipment, but when the gas concentration information exceeds the first concentration range for a long time or exceeds the second concentration range, It indicates that the air quality at this time is very poor, and the user needs to be reminded to leave the target area. At this time, a reminder instruction is generated according to the concentration information. Wherein, the second concentration range is greater than the first concentration range. For example, when the gas is oxygen, the first concentration range can be 20%, that is, when the oxygen is lower than 20%, the first control instruction is generated; the second concentration range can be 15%, that is, when the oxygen is lower than 15%, , a reminder command is generated.

[0070] In step S207, a reminder is issued according to the reminder instruction, wherein the reminder includes: a sound reminder and a light reminder.

[0071] Specifically, the terminal or other device is controlled to issue a reminder according to the reminder instruction, and the reminder may be a sound reminder or a light reminder. Wherein, the sound reminder can be reminded through a speaker, and the speaker can be set on the terminal, or can be set on other equipment or a certain position in the room; the light-emitting reminder can be through the light-emitting device on the terminal, or directly through the room. Lamps or other light emitting devices. It should be noted that when the device that sends out the reminder is not on the terminal, the terminal sends a reminder instruction wirelessly to control the device to send out a reminder, which is not limited in this embodiment of the present invention.

[0072] As can be seen from the above, the control method in the embodiment of the present invention detects whether there is a person in the target area, detects the air information in the target area when there is a person, and controls the target device to perform air treatment when the air quality is poor. And remind the user to leave the target area when the air quality is poor. On the one hand, it can automatically start the air treatment equipment when the air quality is poor, without the need for the user to actively open it, which is more intelligent and convenient; on the other hand, it can only be started when there are people. It saves energy consumption, improves user experience, and reminds users to leave in time when the air quality deteriorates, ensuring the personal safety of users.

[0073] image 3 It is a flow chart of the third embodiment of a control method provided by the embodiment of the present invention. The control method includes the following steps S301-S309. Wherein, in this embodiment, the steps of S301-S307 are the same as figure 2 The steps of S201-S207 in the second embodiment shown are the same and will not be repeated here.

[0074] In step S301, image information in the target area is acquired through a camera or sensing information in the target area is acquired through an infrared sensor.

[0075] In step S302, the image information or sensory information is identified, and whether there are human features in the image information or sensory information is judged.

[0076] In step S303, air information in the target area is detected. Wherein, the air information includes concentration information of at least one gas.

[0077] In step S304, if the concentration information of the at least one gas exceeds a preset first concentration range, a first control instruction is generated according to the concentration information.

[0078] In step S305, the first control command is sent to the target device, so as to control the target device to perform air treatment.

[0079] In step S306, if the concentration information exceeds the preset second concentration range or the time for which the concentration information exceeds the preset first concentration range exceeds the preset first time threshold, generate Reminder command.

[0080] In step S307, a reminder is issued according to the reminder instruction, wherein the reminder includes: a sound reminder and a light reminder.

[0081] In step S308, if the concentration information exceeds the preset third concentration range or the time for which the concentration information exceeds the preset second concentration range exceeds the preset second time threshold, generate Second control command.

[0082] Specifically, when the gas concentration information exceeds the second concentration range, the user has been reminded to leave. If the gas concentration information exceeds the third concentration range or the time for exceeding the second concentration range exceeds the preset second The time threshold indicates that the air command in the target area is very poor at this time. At this time, it is necessary to open the doors and windows and activate the alarm bell to avoid accidents such as coma in the target area. At this time, the second control instruction is generated according to the concentration information. Wherein, the third concentration range is greater than the second concentration range. For example, when the gas is oxygen, the first concentration range can be 20%, that is, when the oxygen is lower than 20%, the first control instruction is generated; the second concentration range can be 15%, that is, when the oxygen is lower than 15%, , a reminder instruction is generated; the third concentration range may be 5%, that is, when the oxygen is lower than 5%, it indicates that the air quality in the target area is already very bad at this time, and a second control instruction is generated.

[0083] In step S309, start the alarm bell and open the doors and windows according to the second control instruction.

[0084]Specifically, the door and window are controlled to be opened according to the second control command and the alarm bell is activated. The purpose of opening the door and window is for ventilation, and the purpose of activating the alarm bell is to prevent accidents such as coma of the user in the target area.

[0085] As can be seen from the above, the control method in the embodiment of the present invention detects whether there is a person in the target area, detects the air information in the target area when there is a person, and controls the target device to perform air treatment when the air quality is poor. When the air quality is poor, the user is reminded to leave the target area, and when the air quality is particularly poor, the doors and windows are forced to open. On the one hand, the air treatment equipment can be automatically activated when the air quality is poor, and the user does not need to actively open it, which is more intelligent and convenient; It starts only when there are people, which saves energy consumption, improves user experience, and reminds users to leave in time when the air quality deteriorates, ensuring the personal safety of users.
