Referring to fig. 2, an embodiment of the present application provides a method for controlling a sleep mode of an air conditioner, which is mainly applied to the server 200 in fig. 1 for illustration, and the method includes steps S210 to S240, specifically as follows:
s210, when the air conditioner is operated in the heating mode, the body surface temperature value of the target object is acquired.
The target object is a movable object in a space where an indoor unit of the air conditioner is located, for example, a user entering the space where the air conditioner is located, and the body surface temperature value is a surface temperature value of the target object; it will be appreciated that the body surface temperature value may be used to reflect a temperature value perceived by the target object, or a temperature value of the region in which the target object is located.
Specifically, a human body surface temperature sensor can be arranged in an indoor unit of the air conditioner, and the human body surface temperature value of a target object in a space where the indoor unit is positioned is detected in real time through the human body surface temperature sensor; peripheral equipment with a temperature sensor, such as an intelligent bracelet, remote control equipment, an intelligent pillow, an intelligent mattress and the like, which are in wireless connection with the air conditioner, can also be arranged, and the body surface temperature value of the target object is detected through the intelligent equipment.
After the air conditioner is started and runs for a period of time in a sleep mode, the air conditioner can acquire the body surface temperature value of the target object at the current moment through a human body surface temperature sensor or intelligent equipment with a temperature sensor connected with the air conditioner.
When the air conditioner works in a heating mode, air-conditioning air (hot air) generated by the air conditioner easily floats upwards, and in addition, in order to reduce influence of blowing sense on sleeping of a user, disturbance on indoor air flow is generally avoided as much as possible in the running process of the air conditioner in the sleeping mode, so that the temperature of a high place in an acting space of the air conditioner is higher after the air conditioner enters the sleeping mode for a long time, the temperature perceived by a user at a low place in the space is lower, and the user is possibly awakened by cold; thus, in one embodiment, obtaining the body surface temperature value of the target object may specifically include: acquiring preset temperature detection trigger time and the running time of the air conditioner entering a sleep mode; and if the running time length reaches the temperature detection trigger time, acquiring a body surface temperature value of the target object at the current moment.
The temperature detection trigger time may be set according to actual conditions, for example, may be set to 2 hours, 4 hours, 6 hours, or the like.
Specifically, the air conditioner is provided with a timer, and the timer is controlled to work after entering the sleep mode so as to acquire the running time of entering the sleep mode; when the operation time length reaches the temperature detection trigger time, the body surface temperature value of the target object at the current moment is obtained, so that the operation parameters of the air conditioner can be adjusted according to the body surface temperature value at the current moment, and the situation that the user is awakened due to the fact that the temperature perceived by the user is low after the user enters a sleep mode is avoided.
Further, considering that if the body surface temperature value of the user is frequently collected and the operation parameters of the air conditioner are adjusted according to the body surface temperature value during the whole sleeping time of the user, the sleeping of the user is disturbed due to the change of the operation sound, indoor air flow, indoor temperature and other environmental factors of the air conditioner in the process of adjusting the operation parameters of the air conditioner; thus, in one embodiment, obtaining a body surface temperature value of a target object includes: acquiring biological characteristic data of a target object; determining a sleep state of the target object according to the biological characteristic data; and if the sleeping state of the target object is a deep sleeping state, acquiring the body surface temperature value of the target object.
The biological characteristic data comprise but are not limited to body movement data, heartbeat data and the like of a target object, wherein the body movement data refer to dynamic data caused by actions such as breathing, turning and the like of a user, and the heartbeat data refer to heartbeat rate data of the user; among these, the entire sleep time period often includes the following various states: the biological characteristic data corresponding to different sleep states are different in the awake state, the light sleep state, the deep sleep state or the rapid eye movement state.
Specifically, a body sensing radar sensor can be arranged in an indoor unit of the air conditioner, and biological characteristic data of a target object in a space where the indoor unit is positioned is detected in real time through the body sensing radar sensor; an intelligent device connected with the air conditioner and provided with a biological characteristic sensor, such as an intelligent bracelet, a remote control device, an intelligent pillow, an intelligent mattress and the like, can be also arranged, and biological characteristic data of a target object can be detected through the intelligent device.
After the air conditioner acquires the biological characteristic data of the target object, the biological characteristic data can be sent to the cloud server, and the cloud server predicts the sleep state of the target object according to the biological characteristic data of the target object; the prediction model for determining the sleep state may be stored in advance, and after the biometric data of the target object is acquired, the biometric model may be input into the prediction model, and the sleep state of the target object may be acquired by the prediction model.
After the sleeping state of the target object is determined, if the sleeping state of the target object is a deep sleeping period state, acquiring a body surface temperature value of the target object, and subsequently adjusting the operation parameters of the air conditioner according to the body surface temperature value, so that the operation parameters of the air conditioner are adjusted in the deep sleeping state of the user, and interference of the operation sound of the air conditioner, the indoor air flow, the indoor temperature and other environmental factors on sleeping of the user in the process of adjusting the operation parameters of the air conditioner is avoided.
S220, calculating a temperature difference between the body surface temperature value and a preset temperature value.
Wherein the predetermined temperature value may be set according to actual conditions, for example, the predetermined temperature may be set to a temperature value (e.g., 24 degrees celsius) that is comfortable to the human body or a temperature value set by the user. The temperature difference between the body surface temperature value and the preset temperature value can be used for reflecting the difference between the temperature value perceived by the user and the preset temperature value.
S230, if the temperature difference is larger than a preset temperature threshold and the body surface temperature value is larger than a preset temperature value, controlling the air deflector to sweep air up and down between a reference air sweeping angle and a maximum air sweeping angle.
The preset temperature threshold may be set to 1 degree celsius, 2 degrees celsius, 3 degrees celsius, or the like, which is not limited herein. Specifically, the preset temperature threshold is used for measuring the deviation degree between the body surface temperature value and the preset temperature value, if the temperature difference is larger than the preset temperature threshold, the body surface temperature value is larger than the preset temperature value, namely, the fact that the difference between the temperature value perceived by a user and the preset temperature value is larger is judged, and the follow-up adjustment of the operation parameters of the air conditioner can be carried out to carry out temperature compensation, so that the temperature perceived by the user reaches or approaches to the preset temperature value, the situation that the body surface temperature value is too high or too low compared with the preset temperature value is avoided, and the use experience of the user is improved.
The maximum wind sweeping angle refers to the maximum rotation angle of the wind deflector in the vertical direction; the reference wind-sweeping angle refers to a wind-guiding angle between a maximum wind-sweeping angle and a minimum wind-guiding angle in the vertical direction, and specifically may be a wind-guiding angle set by a user, or may be an angle corresponding to an angular bisector between the maximum wind-sweeping angle and the minimum wind-sweeping angle, which is not limited herein. Referring to fig. 3, fig. 3 shows schematic diagrams corresponding to different wind sweeping angles, wherein the upper and lower wind deflectors do vertical rotation motion, and the vertical wind sweeping angle is alpha.
Further, in an embodiment, the reference wind sweeping angle may be preset to be an angle corresponding to an angular bisector between a maximum wind sweeping angle and a minimum wind sweeping angle, and after the object position information of the target object is obtained, the reference wind sweeping angle is adjusted according to the object position information, so that air conditioning wind generated by the air conditioner is prevented from blowing to the user.
Specifically, when the temperature difference is greater than a preset temperature threshold value and the body surface temperature value is greater than a preset temperature value, namely the temperature sensed by the target object is greater than the preset temperature, and the temperature sensed by the target object is higher than the preset temperature, the possibility that the target object is hot-awakened is greater, at the moment, the air deflector is controlled to sweep air up and down between a reference air sweeping angle and a maximum air sweeping angle, so that air conditioning air generated by the air conditioner is concentrated in an upper half air sweeping area, and hot air blown by the air conditioner is prevented from being directly blown to the target object.
Further, in order to further reduce the body surface temperature value corresponding to the target object, in an embodiment, after the step of controlling the air deflector to sweep air up and down between the reference wind sweeping angle and the maximum wind sweeping angle, the method further includes: reducing the rotating speed of the indoor fan; and/or reduce the operating frequency of the compressor.
The rotating speed of the indoor fan is reduced, so that the air output of air-conditioning air of the air conditioner can be reduced; the working frequency of the compressor is reduced, and the temperature of air-conditioning wind of the air conditioner can be reduced in a heating mode. Specifically, after the air deflector is controlled to sweep air up and down between the reference air sweeping angle and the maximum air sweeping angle, the rotating speed of the indoor fan can be only reduced; it is also possible to reduce only the operating frequency of the compressor; the fan rotating speed of the indoor fan can be reduced, and the working frequency of the compressor can be reduced.
The fan rotating speed of the indoor fan and/or the working frequency of the compressor are/is reduced, so that the air output of hot air of the air conditioner and/or the temperature value of the hot air are/is reduced, the body surface temperature value corresponding to the target object is further effectively reduced, and the temperature perceived by a user reaches or is close to a preset temperature value.
S240, if the temperature difference is larger than a preset temperature threshold and the body surface temperature value is smaller than a preset temperature value, controlling the air deflector to sweep air up and down between a reference air sweeping angle and a minimum air sweeping angle.
The minimum wind sweeping angle refers to the minimum rotation angle of the wind deflector in the vertical direction. When the temperature difference is larger than the preset temperature threshold value and the body surface temperature value is larger than the preset temperature value, the temperature perceived by the target object is larger than the preset temperature difference, the temperature perceived by the target object is lower than the preset temperature, the possibility that the target object is frozen and awakened is larger, at the moment, the air deflector is controlled to sweep air up and down between the reference air sweeping angle and the minimum air sweeping angle, so that air conditioning air generated by the air conditioner is concentrated in a lower half air sweeping area, namely, hot air blown by the air conditioner is blown to the target object.
Further, in order to enable the air conditioner wind to be accurately blown to the user, in one embodiment, the step of controlling the wind deflector to sweep wind up and down between the reference wind sweeping angle and the minimum wind sweeping angle includes: acquiring the opposite position information of the target object based on the body surface temperature value of the target object; and adjusting the reference wind sweeping angle of the wind deflector according to the object position information, and controlling the wind deflector to sweep wind up and down between the reference wind sweeping angle and the minimum wind sweeping angle.
Specifically, a body surface temperature value of the target object may be obtained by a body surface temperature sensor, and the body surface temperature value may include body surface temperature distribution data; after the body surface temperature value of the target object is obtained, the object position information of the target object (namely, a user) is determined by analyzing the human body surface temperature distribution data, and then the reference wind sweeping angle of the wind deflector is adjusted based on the object position information, so that the air conditioner wind energy blows to the target object when the wind deflector sweeps up and down between the reference wind sweeping angle and the minimum wind sweeping angle, and the body surface temperature of the target object is improved.
Further, in order to further improve the body surface temperature value corresponding to the target object, in an embodiment, after the step of controlling the air deflector to sweep air up and down between the reference wind sweeping angle and the minimum wind sweeping angle, the method further includes: the rotating speed of the indoor fan is improved; and/or to increase the operating frequency of the compressor.
The fan rotating speed of the indoor fan is increased, so that the hot air volume of a direct-blowing target object (namely a user) can be increased; the operating frequency of the compressor is increased, and the temperature of the air-conditioning air blown to the target object is increased in the heating mode.
