Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning control methods, and in particular to a control method for an air conditioner and an air conditioner. Background Art

[0002] With the rapid development of society, the problem of population aging has emerged, and the phenomenon of "empty nesters" is now more common. The health of the elderly has become a hot social issue, attracting widespread attention from all walks of life and urgently needs to be resolved.

[0003] With the rapid economic development, people's living standards are constantly improving. As the popularity of household air conditioners among the masses increases year by year, they play an increasingly important role in daily life. Elderly people are prone to misunderstandings when using air conditioners at home. Improper use will greatly increase the possibility of suffering from "air conditioning disease". The symptoms of air conditioning disease vary slightly due to different adaptability of each person, but usually nasal congestion, dizziness, sneezing, tinnitus, and memory loss are the main manifestations. Some patients may also experience digestive tract symptoms, such as abdominal pain, diarrhea, loss of appetite, etc., as well as fever, fatigue, joint pain and other systemic symptoms.

[0004] In addition, the elderly are more frugal and rarely use the air conditioner. They are not very good at using the air conditioner controller, or they are illiterate and cannot recognize the cooling and heating modes. Once they use the wrong mode, it is easy to cause adverse consequences. For example, it is too hot at night and the air conditioner is turned on by mistake, and the cooling mode is adjusted to heating, and the neck is covered with prickly heat overnight.

[0005] There was even a report that an elderly person living alone stopped breathing at home. Judging from the situation at the scene, the indoor air conditioner was not cooling but hot air. The elderly person may have died of heat stroke, which can be life-threatening if not discovered in time. In other words, the elderly person switched the air conditioner from cooling to heating mode, which caused serious consequences due to improper use.

[0006] Air conditioning achieves the effect of cooling and heating by exchanging energy between the compressor of the outdoor unit and the indoor unit. The air conditioning compressor compresses not air but refrigerant, which circulates in the closed air conditioning system, continuously absorbing the heat of the indoor air, transferring it to the outside and releasing it to the ambient air to achieve the purpose of cooling. Or the refrigerant circulates in reverse, absorbing heat from the outdoor air, bringing the heat indoors and transferring it to the indoor air to achieve the purpose of heating.

[0007] If you switch the air conditioner to heating mode in the summer, it will still blow out hot air, and the indoor temperature will already be hot, and the heat from the hot air will only add to the heat. Summary of the invention

[0072] Figure 2 is a flow chart of a method for controlling an air conditioner according to another exemplary embodiment. DETAILED DESCRIPTION

[0073] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0074] Embodiment 1

[0075] Figure 1 is a flow chart showing a method for controlling an air conditioner according to an exemplary embodiment. Figure 1 , the method comprising:

[0076] Step S11, obtaining a 3D model of the space where the air conditioner is located, and marking the real-time position of the user in the 3D model;

[0077] Step S12: In cooling mode / heating mode, the air outlet direction of the air conditioner is controlled according to the real-time position of the user.

[0078] It should be noted that, in actual practice, the technical solution provided in this embodiment is loaded into the controller of the air conditioner and runs.

[0079] It can be understood that the technical solution provided in this embodiment can accurately control the air conditioner to blow air towards the user by obtaining a 3D model of the space where the air conditioner is located and marking the user's real-time position in the 3D model, thereby improving the energy utilization efficiency of the air conditioner and solving the problem in the prior art that the air sweeping range of the air conditioner cannot be finely controlled.

[0080] In specific practice, before step S11 acquires the 3D model of the space where the air conditioner is located, it also includes:

[0081] A 3D model of the space where the air conditioner is located is established through photos taken by an ordinary camera and scanning information from a millimeter-wave radar, and the 3D model is pre-stored in a database.

[0082] It should be noted that the ordinary camera refers to a camera that does not have special functions such as infrared thermal imaging, but only has human body tracking and image acquisition functions.

[0083] In specific practice, the real-time position of the user is marked in the 3D model in step S11, specifically:

[0084] The user's real-time location is marked in the 3D model through photos taken by an ordinary camera and thermal imaging information from an infrared camera.

[0085] In specific practice, in step S12, the air outlet direction of the air conditioner is controlled according to the real-time position of the user, including:

[0086] In cooling mode, obtain the parts of the human body that are prohibited from being blown by cold air set by the user;

[0087] Control the air outlet direction of the air conditioner to avoid the human body parts that are prohibited from being blown by the cold air;

[0088] and / or,

[0089] In heating mode, obtain the part of the human body where the hot air is blown intensified as set by the user;

[0090] The air outlet direction of the air conditioner is controlled to be toward the part of the human body where the hot air is blown more strongly.

[0091] For example, if the user has a bad lumbar spine and cannot use cold air, the air conditioner's internal control system will automatically identify his position and avoid the air in cooling mode.

[0092] For another example, when the weather turns cooler, the air conditioner heating function is needed. If the user's leg joints are still relatively cold, you can set the hot air to blow more on the leg joints.

[0093] In specific practice, the step of obtaining the human body parts that are prohibited from being blown by cold wind set by the user includes:

[0094] Before setting the cooling mode, the user is reminded to input or select the body parts that are prohibited from being blown by cold air;

[0095] or,

[0096] After the user sets the cooling mode, the user is reminded to input or select the parts of the human body that are prohibited from being blown by cold air.

[0097] In specific practice, the method of obtaining the part of the human body set by the user for enhanced hot air blowing includes:

[0098] Before setting the heating mode, the user is reminded to input or select the body parts that are prohibited from being blown by cold air;

[0099] or,

[0100] After the user sets the heating mode, the user is reminded to input or select the parts of the human body that are prohibited from being blown by cold air.

[0101] It is understandable that the technical solution provided by this embodiment can not only sense the specific location of the user and realize accurate control of the air outlet direction, but also, according to the personalized needs of the user, in cooling mode, obtain the human body parts set by the user for cold air to be prohibited from blowing, and control the air outlet direction of the air conditioner to avoid the human body parts that are prohibited from being blown by cold air; in heating mode, obtain the human body parts set by the user for enhanced hot air blowing, and control the air outlet direction of the air conditioner to be toward the human body parts that are enhanced to be blown by hot air. Accurate air supply can not only reduce the energy loss of the air conditioner, but also deliver the air to the user's comfort zone, which can improve the user experience of the air conditioner and enhance the user's comfort. It solves the problem in the prior art that the air conditioner operation strategy cannot be accurately, timely and effectively adjusted according to the user's physical condition.

[0102] In specific practice, the control method further includes:

[0103] In cooling mode, the user's body surface temperature is detected every first preset time period;

[0104] Determine whether the user's body surface temperature is lower than a first temperature threshold, or exceeds a second temperature threshold, and if so, control the buzzer to sound an alarm until receiving feedback information sent by the user through the remote control to confirm that the user has known the reminder;

[0105] and / or,

[0106] In heating mode, the user's body surface temperature is detected every second preset time period;

[0107] Determine whether the user's body surface temperature is lower than a first temperature threshold, or exceeds a second temperature threshold. If so, control the buzzer to sound an alarm until receiving feedback information sent by the user through the remote control to confirm that the reminder has been known.

[0108] It should be noted that the first preset time length and the second preset time length are set according to user needs, or are set according to historical experience values ​​or experimental data.

[0109] The first preset duration and the second preset duration may be set equal; or,

[0110] The first preset time length and the second preset time length may be set to be unequal.

[0111] The first temperature threshold and the second temperature threshold are set according to user needs, or according to historical experience values ​​or experimental data. For example, the first temperature threshold is set to 35°, and the second temperature threshold is set to 38°.

[0112] It is understandable that elderly people at home may easily switch the heating mode to cooling mode or vice versa due to poor memory or eyesight. Therefore, whether it is cooling mode or heating mode, the user's body surface temperature must be detected every preset time to determine whether the user has heat stroke due to the wrong mode or staying in the air conditioning heating mode for too long; or to determine whether the user has hypothermia due to the wrong mode or staying in the air conditioning cooling mode for too long.

[0113] The technical solution provided in this embodiment detects the user's body surface temperature in real time when the air conditioner is running, monitors health data, and avoids burdening the body due to improper use of the air conditioner. The user can set the scanning time interval and temperature alarm range. If the user's body temperature regulation is unbalanced, the air conditioner buzzer will start the alarm, which solves the problem in the prior art that when the user's body has an emergency, it cannot effectively respond.

[0114] In specific practice, the control method further includes:

[0115] In the warning mode, obtain the warning area set by the user;

[0116] Every third preset time period, detecting the real-time location of the user;

[0117] If the user's real-time position is detected in the warning area and the user's current posture meets the abnormal posture alarm triggering condition, the buzzer is controlled to sound an alarm until feedback information is received from the user through the remote control confirming that the reminder has been known.

[0118] In specific practice, the control method further includes:

[0119] While acquiring the warning area set by the user, or before acquiring the warning area set by the user, or after acquiring the warning area set by the user, receiving an abnormal posture alarm trigger condition selected by the user;

[0120] The abnormal posture alarm triggering conditions include: lying flat, half lying or sitting for a long time.

[0121] It should be noted that the third preset duration is set according to user needs, or according to historical experience or experimental data. The third preset duration can be set equal to the first preset duration and the second preset duration, or the third preset duration can be set unequal to the first preset duration and the second preset duration.

[0122] It is understandable that for the elderly, bumps and collisions in daily life can cause great harm to the body. The warning areas can be places in the house where bumps and collisions are prone to occur and where pain may occur due to sitting for a long time, including: kitchen floor, bathroom door, room connection, dining table area, balcony, etc. The control algorithm will focus on the warning areas marked in advance by the user.

[0123] It can be understood that the technical solution provided in this embodiment can detect the user's posture in a specific warning area, so as to determine whether an emergency situation has occurred, and then take emergency rescue measures, thereby ensuring the comfort of the elderly in using air conditioning, while taking into account health care for the elderly group, and does not require complicated operations and has adaptive capabilities.

[0124] In specific practice, detecting the user's body surface temperature includes:

[0125] Detect the temperature values ​​of N preset core parts of the user's body surface, N ≥ 2;

[0126] The N temperature values ​​are weighted and summed, and the obtained result is used as the user's body surface temperature.

[0127] For example, the air conditioning algorithm selects the temperature of four core points on the body surface (the selected point area is set by the user), and obtains the final result after weighted calculation (Tem = a*tem1+b*tem2+c*tem3+d*tem4). Among them, a, b, c, d are weighted coefficients, and a, b, c, d>0.

[0128] Preferably, the control method further includes:

[0129] In cooling mode, if the user's real-time location is detected to be within a certain space within a threshold time, the air conditioner's sweeping mode is controlled to follow the user's sweeping mode;

[0130] and / or,

[0131] In the heating mode, if it is detected that the user's real-time location is within a threshold time and is always within a certain spatial area, the air-sweeping mode of the air conditioner is controlled to follow the user's air-sweeping mode.

[0132] It should be noted that the threshold duration is set according to user needs, or according to historical experience values ​​or experimental data, for example, set to 20 minutes.

[0133] It is understandable that if the user is confined to a certain area for a period of time, the air conditioner sweeping mode can be changed to follow the user sweeping mode. In this way, the cooling / heating of the air conditioner can be maximized and the energy utilization rate of the air conditioner can be improved.

[0134] In specific practice, the control method further includes:

[0135] In the follow-user air sweeping mode, the air conditioner is controlled to sweep air toward the parts of the user's body surface with uneven temperature.

[0136] It is understandable that after setting the follow-the-user air sweeping mode, the air conditioning control algorithm will sweep air to the parts of the user's body surface with uneven temperature, thereby improving the comfort of using the air conditioning.

[0137] Preferably, the control method further includes:

[0138] If, after the control buzzer sounds the alarm for the fourth preset time period, no feedback information is received from the user through the remote controller confirming that the user has known the reminder, an alarm message is sent to the emergency contact person reserved by the system.

[0139] It should be noted that the fourth preset duration is set according to user needs, or according to historical experience values ​​or experimental data, for example, set to 5 minutes.

[0140] Preferably, the control method further includes:

[0141] If no response is received from the emergency contact after the fifth preset time period after sending the alarm message to the emergency contact reserved by the system, the emergency number is dialed to send a voice alarm message.

[0142] It should be noted that the fifth preset duration is set according to user needs, or according to historical experience values ​​or experimental data, for example, set to 10 minutes.

[0143] It can be understood that the technical solution provided in this embodiment is that if the temperature imbalance of the user is not restored for a long time, the air conditioner buzzer will start the alarm. If the user does not confirm on the remote control that he has been aware of the reminder, the emergency contact will be contacted to notify the abnormal situation. If effective communication is still not obtained, the emergency number will be automatically called to inform the abnormal situation and wait for emergency rescue.

[0144] If it is detected that the user is lying at this location, an alarm will be issued. At this time, you need to press the confirmation button on the remote control to cancel the alarm. If no such operation is performed within a period of time, the system will call the emergency number and notify the emergency contact to prevent the user from not receiving timely rescue after falling.

[0145] The control method of this embodiment ensures the comfort of the elderly in using air conditioning, while taking into account health care for the elderly group. It does not require complicated operations and has a good user experience and high satisfaction.

[0150] Step S23, cooling air outlet control:

[0152] Control the air outlet direction of the air conditioner to avoid the human body parts that are prohibited from being blown by the cold air;

[0153] Detecting the user's body surface temperature at first preset time intervals;

[0164] Step S26: if the buzzer is controlled to sound the alarm for a fourth preset time period and no feedback information is received from the user through the remote controller confirming that the user has known the reminder, an alarm message is sent to the emergency contact person reserved by the system;

[0165] Step S27: If no response is received from the emergency contact after sending the alarm message to the emergency contact reserved by the system for the fifth preset time period, dial the emergency number and send a voice alarm message.

[0166] It should be noted that, in actual practice, the technical solution provided in this embodiment is loaded into the controller of the air conditioner and runs.

[0167] It can be understood that the technical solution provided in this embodiment can accurately control the air conditioner to blow air towards the user by obtaining a 3D model of the space where the air conditioner is located and marking the user's real-time position in the 3D model, thereby improving the energy utilization efficiency of the air conditioner and solving the problem in the prior art that the air sweeping range of the air conditioner cannot be finely controlled.

[0168] Furthermore, the technical solution provided by this embodiment can not only sense the specific location of the user and realize accurate control of the air outlet direction, but also, according to the personalized needs of the user, in cooling mode, obtain the human body parts set by the user for cold air to be prohibited from blowing, and control the air outlet direction of the air conditioner to avoid the human body parts that are prohibited from being blown by cold air; in heating mode, obtain the human body parts set by the user for enhanced hot air blowing, and control the air outlet direction of the air conditioner to be toward the human body parts that are enhanced to be blown by hot air. Accurate air supply can not only reduce the energy loss of the air conditioner, but also deliver the air to the user's comfort zone, which can improve the user experience of the air conditioner and enhance the user's comfort.
