Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning control, and specifically provides an air conditioning control method, system and air conditioner. Background Art

[0002] Air conditioners have become essential household appliances in many homes. During daily use, doors and windows are often kept closed to better and more quickly regulate the indoor temperature and for energy conservation. This often leads to a decrease in indoor air quality and oxygen content after prolonged use. Therefore, fresh air devices or air conditioners with fresh air functions have become increasingly popular in families, hoping to maintain a comfortable indoor temperature while also maintaining good indoor air quality.

[0003] However, traditional air conditioning controls often rely on continuous cooling / heating based on ambient temperature to achieve room temperature regulation. Fresh air devices are often manually turned on and off on a timed basis. As a result, existing temperature regulation and / or fresh air control functions sometimes fail to meet the needs of indoor occupants for ambient temperature and oxygen content. Therefore, how to control the ambient temperature regulation and / or fresh air function based on real-time human body data to simultaneously meet people's needs for indoor temperature and air quality, improve user experience, and achieve energy savings has become an urgent problem to be solved.

[0073] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0074] It should be understood by those skilled in the art that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art may make adjustments as needed to adapt to specific applications.

[0075] Read First Figure 1 , Figure 1 1 is a flow chart of the main steps of the air conditioning control method according to an embodiment of the present invention. The air conditioning control method according to an embodiment of the present invention includes:

[0076] Step S1: Obtain the user's blood oxygen saturation and body surface temperature;

[0077] Step S2: Based on the blood oxygen saturation and the body surface temperature difference, control the ambient temperature adjustment function and / or the fresh air function.

[0078] In step S1, in the embodiment of the present invention, the user's blood oxygen saturation is obtained through a smart bracelet. It should be noted that the user's blood oxygen saturation can also be obtained through other smart wearable devices, such as smart bracelets, smart rings, finger-clip oximeters, etc. Alternatively, the user's blood oxygen saturation can be obtained through other blood oxygen saturation detection devices, as long as the device has data communication capabilities and the blood oxygen saturation data can be obtained by other devices.

[0079] In an embodiment of the present invention, the user's body surface temperature is measured by an infrared body temperature detection device installed on the air conditioner or installed independently. The infrared body temperature detection device can also be used to detect whether there is a person in the air conditioning operating area, and the control method of step S2 can be triggered when a person is detected in the air conditioning operating area.

[0080] In the embodiments of the present invention, the air conditioner operating mode controlled by the method of the present invention is referred to as the intermittent autonomous temperature control mode. The user can configure the method for the air conditioner to enter the intermittent autonomous temperature control mode based on actual circumstances. For example, the method can be selected directly through the air conditioner remote control or triggered by a certain condition, such as the aforementioned method of triggering the infrared body temperature detection device.

[0081] Next, combine Figure 2 and Figure 3The detailed steps of step S2 are described. In an embodiment of the present invention, the air conditioner is preferably a fresh air air conditioner with a fresh air function; the air conditioner is also equipped with a built-in infrared body temperature detection device, and the air conditioner controller can detect whether the user is in the air conditioner working area and the user's body surface temperature through the infrared body temperature detection device; and the air conditioner can obtain the user's blood oxygen saturation data collected by the smart wearable device through Wi-Fi, Bluetooth or other wireless communication methods; the air conditioner control method of the present invention is implemented by the air conditioner controller.

[0082] Figure 2 The following is a detailed flow chart of step S2 when the air conditioner is operating in cooling mode.

[0083] In step S100, the air conditioner operates in cooling mode. The air conditioner is set to automatically enter the intermittent autonomous temperature control mode after detecting that a person enters the room. When the built-in infrared body temperature detection device of the air conditioner detects that a person enters, the air conditioner enters the intermittent autonomous temperature control mode.

[0084] In step S101, after the air conditioner enters the intermittent autonomous temperature control mode, it first determines whether the user's blood oxygen saturation is greater than or equal to a first blood oxygen saturation threshold.

[0085] It should be noted that blood oxygen saturation is the percentage of the volume of oxygenated hemoglobin bound to oxygen in the blood to the total volume of hemoglobin that can be bound, that is, the concentration of blood oxygen in the blood. It is an important physiological parameter of the respiratory circulation. Therefore, detecting arterial blood oxygen saturation can estimate the oxygenation of the lungs and the oxygen-carrying capacity of hemoglobin. When the blood oxygen saturation is lower than the normal value, it will directly affect the normal metabolism of cells and even threaten human life in severe cases. In an embodiment of the present invention, the blood oxygen saturation adopts the blood oxygen saturation of arterial blood. For most people, the normal value of the blood oxygen saturation of arterial blood is usually not less than 95%. Therefore, the first blood oxygen saturation threshold can be set to 95%.

[0086] If the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S102 is executed. In step S102, the user's blood oxygen saturation is at a normal level, so there is no need to enable the fresh air function. Only the cooling function is enabled to bring the actual indoor ambient temperature to the user's preset ambient temperature. After the current state continues for the first duration, step S104 is executed to continue determining the user's blood oxygen saturation.

[0087] If the blood oxygen saturation is less than the first blood oxygen saturation threshold, step S103 is executed. In step S103, the user's blood oxygen saturation is lower than normal. Therefore, the fresh air function can be activated to increase the oxygen content in the indoor air, thereby improving the user's blood oxygen saturation. At this time, the cooling function and the fresh air function are simultaneously activated to bring the actual indoor ambient temperature to the user's preset ambient temperature. After the current state continues for the second duration, step S104 is executed to continue determining the user's blood oxygen saturation.

[0088] In step S104, a body surface temperature sampling moment is set to collect the user's body surface temperature, and then it is determined whether the user's blood oxygen saturation is greater than or equal to a first blood oxygen saturation threshold.

[0089] When the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S105 is executed. In step S105, considering that the air conditioning refrigeration has been running for a period of time, the ambient temperature is usually near the room temperature set by the user. At this time, for energy saving considerations, the air conditioning compressor is turned off and the cooling is suspended, but the air conditioning continues to supply air, so that the previous cooling effect of the air conditioning can still be circulated throughout the house, so that while the air conditioning saves energy, the change in ambient temperature can also be reduced, thereby improving user comfort. In addition, the user's blood oxygen saturation is at a normal level, so the fresh air function is turned off. After the current state continues to run for a third duration, step S107 is executed to determine the change in body surface temperature.

[0090] If the blood oxygen saturation is less than the first blood oxygen saturation threshold, step S106 is executed. In step S106, for the same reason as step S105, the air conditioner compressor is turned off, cooling is suspended, and air conditioning is started. At this point, the user's blood oxygen saturation is lower than normal, and the fresh air function is activated. After the current state continues for a fourth duration, step S107 is executed to determine changes in body surface temperature.

[0091] In step S107, a surface temperature sampling time is also set, the current surface temperature is collected, and the difference between the current user surface temperature and the previous surface temperature is calculated to obtain the surface temperature difference. It is then determined whether the surface temperature difference is greater than the surface temperature difference threshold.

[0092] When the air conditioner is operating in cooling mode, the body surface temperature difference = current body surface temperature - previous body surface temperature, and when the result of the body surface temperature difference is a negative value, the body surface temperature difference is 0. As an example, the body surface temperature difference threshold is set to 0.5°C.

[0093] It's important to note that the reason we use body surface temperature difference as the basis for indoor temperature control in air conditioning is that it not only reflects the changing trends of the indoor ambient temperature, but also improves user comfort by controlling the temperature difference within a narrow range. This also eliminates control differences caused by differences in user basal body temperature, improving the applicability and accuracy of the control method.

[0094] When the body surface temperature difference is greater than the body surface temperature difference threshold, step S108 is executed to further determine the user's blood oxygen saturation.

[0095] If the surface temperature difference is greater than the surface temperature difference threshold, and the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, execute step S109. In step S109, it can be seen from the calculation method of the surface temperature difference that the surface temperature is on an upward trend at this time, the human body feels hotter, and the trend of the ambient temperature change is also getting hotter. At this time, the cooling function can be turned on to lower the ambient temperature, and the user's surface temperature will also drop accordingly, making the user feel comfortable. At this time, the user's blood oxygen saturation is at a normal level, so the fresh air function is turned off. After the current state continues to run for the fifth duration, it returns to execute step S104, and the cycle continues to control the cooling function and / or fresh air function according to the surface temperature difference and blood oxygen saturation.

[0096] If the skin temperature difference is greater than the skin temperature difference threshold and the blood oxygen saturation is less than the first blood oxygen saturation threshold, step S110 is executed. In step S110, the cooling function may be activated for the same reason as step S109. At the same time, because the user's blood oxygen saturation is below normal, the fresh air function is activated. After the current state continues for a sixth duration, the process returns to step S104, and the cycle continues to control the cooling function and / or the fresh air function based on the skin temperature difference and blood oxygen saturation.

[0097] When the body surface temperature difference is less than or equal to the body surface temperature difference threshold, step S111 is executed to further determine the user's blood oxygen saturation.

[0098] If the body surface temperature difference is less than or equal to the body surface temperature difference threshold, and the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S112 is executed. In step S112, at this time, since the body surface temperature difference has not changed much, or the user's body surface temperature is getting lower than the previous moment, it means that the air conditioning cooling capacity can meet or exceed the needs of ambient temperature control. For the same energy-saving reasons as step S105, the air conditioning compressor is turned off, cooling is suspended, and air conditioning is supplied. At the same time, the user's blood oxygen saturation is at a normal level, so the fresh air function is turned off. After the current state continues to run for the seventh duration, the process returns to step S107, and the cycle continues to control the cooling function and / or the fresh air function based on the body surface temperature difference and blood oxygen saturation.

[0099] If the skin temperature difference is less than or equal to the skin temperature difference threshold, and the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S113 is executed. In step S113, for the same energy-saving reasons as step S112, the air conditioning compressor is turned off, cooling is suspended, and air conditioning is switched on. At the same time, the user's blood oxygen saturation is lower than normal, so the fresh air function is enabled. After the current state continues for the eighth duration, the process returns to step S107, looping and continuing to control the cooling function and / or fresh air function based on the skin temperature difference and blood oxygen saturation.

[0100] It should be noted that the current moment in the sampling time for calculating the surface temperature difference is fixed as the moment in S107 when the surface temperature difference needs to be determined; the previous moment may also change due to the different steps executed by the air conditioner during the real-time detection of the individual's status. For example, the moment before the first surface temperature calculation upon entering intermittent autonomous temperature control mode is the moment when step S104 is executed, and the time interval at this time is the third duration or the fourth duration. In the continuous control process, after executing step S112 or S113, the process returns to step S107. At this time, the surface temperature used for calculating the surface temperature difference is the surface temperature data obtained during the two consecutive executions of S107.

[0101] Continue reading Figure 3 , Figure 3 The following is a detailed flow chart of step S2 when the air conditioner is operating in heating mode.

[0102] In step S200, the air conditioner operates in a heating mode, and is manually set by a user to enter an intermittent autonomous temperature control mode.

[0103] In step S201, after the air conditioner enters the intermittent autonomous temperature control mode, it first determines whether the user's blood oxygen saturation is greater than or equal to a first blood oxygen saturation threshold.

[0104] If the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S202 is executed. In step S202, the user's blood oxygen saturation is at a normal level, so there is no need to enable the fresh air function. Only the heating function is enabled to bring the actual indoor ambient temperature to the user's preset ambient temperature. After the current state continues for the first duration, step S204 is executed to continue determining the user's blood oxygen saturation.

[0105] If the blood oxygen saturation is less than the first blood oxygen saturation threshold, step S203 is executed. In step S203, the user's blood oxygen saturation is lower than normal. Therefore, the fresh air function can be activated to increase the oxygen content in the indoor air, thereby improving the user's blood oxygen saturation. At this time, the heating function and the fresh air function are simultaneously activated to bring the actual indoor ambient temperature to the user's preset ambient temperature. After the current state continues for the second duration, step S204 is executed to continue determining the user's blood oxygen saturation.

[0106] In step S204, a body surface temperature sampling moment is set to collect the user's body surface temperature, and then it is determined whether the user's blood oxygen saturation is greater than or equal to a first blood oxygen saturation threshold.

[0107] When the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S205 is executed. In step S205, considering that the air conditioning heating has been running for a period of time, the ambient temperature is usually near the room temperature set by the user. At this time, for energy saving considerations, the air conditioning compressor is turned off and the heating is suspended, but the air conditioning continues to supply air, so that the previous heating effect of the air conditioning can still be circulated throughout the house, and the change in ambient temperature can also be reduced to improve user comfort. In addition, the user's blood oxygen saturation is at a normal level, so the fresh air function is turned off. After the current state continues to run for the third duration, step S207 is executed to determine the change in body surface temperature.

[0108] If the blood oxygen saturation is less than the first blood oxygen saturation threshold, step S206 is executed. In step S206, for the same reason as step S205, the air conditioning compressor is turned off, heating is suspended, and air conditioning is activated. At this point, the user's blood oxygen saturation is lower than normal, and the fresh air function is activated. After the current state continues for the fourth duration, step S207 is executed to determine changes in body surface temperature.

[0109] In step S207, a skin temperature sampling time is also set, the skin temperature at the current time is collected, and the difference between the current skin temperature of the user and the skin temperature at the previous sampling time is calculated to obtain the skin temperature difference. It is then determined whether the skin temperature difference is greater than the skin temperature difference threshold.

[0110] When the air conditioner is operating in heating mode, the body surface temperature difference = the previous moment's body surface temperature - the current body surface temperature, and when the result of the body surface temperature difference is a negative value, the body surface temperature difference is 0. As an example, the body surface temperature difference threshold is set to 0.5°C.

[0111] When the body surface temperature difference is greater than the body surface temperature difference threshold, step S208 is executed to further determine the user's blood oxygen saturation.

[0112] If the surface temperature difference is greater than the surface temperature difference threshold, and the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, execute step S209. In step S209, it can be seen from the calculation method of the surface temperature difference that the surface temperature is decreasing at this time, the human body feels colder, and the trend of the ambient temperature change is also cooling. At this time, the heating function can be turned on. When the ambient temperature rises, the surface temperature will also rise, so that the user is in a comfortable environment. At the same time, the user's blood oxygen saturation is at a normal level, so the fresh air function is turned off. After the current state continues to run for the fifth duration, it returns to execute step S204, and the cycle continues to control the cooling function and / or fresh air function according to the surface temperature difference and blood oxygen saturation.

[0113] If the skin temperature difference is greater than the skin temperature difference threshold and the blood oxygen saturation is less than the first blood oxygen saturation threshold, step S210 is executed. In step S210, the cooling function may be enabled for the same reason as step S209. At the same time, because the user's blood oxygen saturation is below normal, the fresh air function is enabled. After the current state continues for the sixth duration, the process returns to step S204, and the cycle continues to control the cooling function and / or the fresh air function based on the skin temperature difference and blood oxygen saturation.

[0114] When the body surface temperature difference is less than or equal to the body surface temperature difference threshold, step S211 is executed to further determine the user's blood oxygen saturation.

[0115] If the body surface temperature difference is less than or equal to the body surface temperature difference threshold, and the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S212 is executed. In step S212, at this time, since the body surface temperature difference has not changed much, or the user's body surface temperature is increasing relative to the previous moment, it means that the air conditioning heating amount can meet or exceed the needs of ambient temperature control. For the same energy-saving reasons as step S205, the air conditioning compressor is turned off, heating is suspended, and air conditioning is supplied. At the same time, the user's blood oxygen saturation is at a normal level, so the fresh air function is turned off. After the current state continues to run for the seventh duration, the process returns to step S207 and the cycle continues to control the cooling function and / or fresh air function based on the body surface temperature difference and blood oxygen saturation.

[0116] If the skin temperature difference is less than or equal to the skin temperature difference threshold, and the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S213 is executed. In step S213, for the same energy-saving reasons as step S212, the air conditioning compressor is turned off, heating is suspended, and air conditioning is turned on. At the same time, the user's blood oxygen saturation is lower than normal, so the fresh air function is turned on. After the current state continues for the eighth duration, the process returns to step S207, and the cycle continues to control the cooling function and / or fresh air function based on the skin temperature difference and blood oxygen saturation.

[0117] It should be noted that the current moment in the sampling time for calculating the body surface temperature difference is fixed to the moment in S207 when the body surface temperature difference needs to be determined; the previous moment will vary depending on the step being executed in the air conditioning control. For example, the moment before the first calculation of the body surface temperature upon entering intermittent autonomous temperature control mode is the moment when step S204 is executed, and the time interval at this time is the third duration or the fourth duration. During continuous control, after executing step S212 or S213, the process returns to step S207. At this time, the body surface temperature used for calculating the body surface temperature difference is the body surface temperature data obtained during two consecutive executions of S207.

[0118] It should be noted that the settings for the first to eighth durations when the air conditioner is operating in cooling mode can be all the same, different, or partially the same; similarly, the settings for the first to eighth durations when the air conditioner is operating in heating mode can be all the same, different, or partially the same. Users can set these based on actual conditions such as air conditioner power, fresh air power, and room conditions. As an example, the first and second durations can be based on the maximum time required for the actual ambient temperature to reach the user-set ambient temperature in cooling mode after the air conditioner enters intermittent autonomous temperature control mode.

[0119] As an example, when the air conditioner operates in cooling mode, the first duration and the second duration can also be set to 60 minutes; the third duration and the fourth duration can also be set to 30 minutes; the fifth duration and the sixth duration can also be set to 25 minutes; and the seventh duration and the eighth duration can also be set to 25 minutes.

[0120] As an example, when the air conditioner works in heating mode, the 1st duration and the 2nd duration can also be set to 60 minutes; the 3rd duration and the 4th duration can also be set to 30 minutes; the 5th duration and the 6th duration can also be set to 25 minutes; and the 7th duration and the 8th duration can also be set to 25 minutes.

[0121] It should be noted that when blood oxygen saturation and surface temperature difference data are obtained for multiple users within the air-conditioning area, for blood oxygen saturation, the lowest blood oxygen saturation data among all users can be selected as the control basis of the present invention for health-first considerations, thereby ensuring that the blood oxygen saturation of all people in the room is at a normal level as much as possible, prioritizing health. For surface temperature difference, the average surface temperature difference of all people can be selected to meet the ambient temperature requirements of most people. Those skilled in the art may also adopt other solutions to determine the effective blood oxygen saturation and surface temperature difference data for multiple users according to actual circumstances.

[0122] After the fresh air function is turned on, the fresh air supply level can be controlled based on the user's blood oxygen saturation data. As the blood oxygen saturation decreases, the fresh air supply level is increased accordingly. For example, when the blood oxygen saturation is greater than 93%, the fresh air supply level is set to low; when the blood oxygen saturation is greater than 90% but less than or equal to 93%, the fresh air supply level is set to medium; when the blood oxygen saturation is less than 90%, the fresh air supply level is set to high.

[0123] Moreover, when the blood oxygen saturation is low for a long time, it indicates that the person may be in an unhealthy state. Therefore, it can be set that when the user's blood oxygen saturation is lower than the second blood oxygen saturation threshold for a duration greater than the blood oxygen alarm time threshold, an alarm prompt message is sent to the user's designated smart terminal to remind relevant personnel that the user's blood oxygen saturation in the air-conditioned room is continuously low, please check the cause in time. Since the second blood oxygen saturation threshold is the blood oxygen saturation value when the oxygen content in the user's blood is low, the second blood oxygen saturation threshold is lower than the first blood oxygen saturation threshold. As an example, the second blood oxygen saturation threshold can be set to 90%, and the blood oxygen alarm time threshold can be set to 2 hours. Those skilled in the art can also set other values according to actual conditions.

[0124] In another embodiment, the fresh air function is a fresh air function of an independent fresh air device. The fresh air device can interact with the air conditioning controller through communication methods such as Wi-Fi and Bluetooth. The air conditioning controller controls the operation of the fresh air device through data communication according to the method of the present invention.

[0125] In another embodiment, the room is equipped with both independent fresh air equipment and fresh air air conditioners. The fresh air equipment can exchange data with the controller of the fresh air air conditioner through communication methods such as Wi-Fi and Bluetooth. At this time, the controller of the fresh air air conditioner can simultaneously control the fresh air function of the fresh air air conditioner and the fresh air function of the fresh air equipment, and select one of them to work independently or simultaneously.

[0126] Furthermore, the present invention also provides an air conditioning system. Figure 4 As shown, the system includes a server 1, a fresh air air conditioner 2, a smart watch 3, an infrared skin temperature detection device 4, and a router 5. Through the router 5, the server 1, the fresh air air conditioner 2, the smart watch 3, and the infrared skin temperature detection device 4 in the air conditioning system can communicate with each other over the network.

[0127] The fresh air air conditioner 2 is an air conditioner with a built-in fresh air module; the smart watch 2 is used to detect the user's blood oxygen saturation data; the infrared body surface temperature detection device 4 is used to detect the user's body surface temperature; the server 1 obtains the user's blood oxygen saturation and body surface temperature through network communication.

[0128] Server 1 includes a processor and memory. The memory can be configured to store the air conditioning control method for executing the above-described method embodiment. The program can be loaded and executed by the processor to implement the above-described air conditioning control method. The control instructions generated by server 1 are sent to fresh air air conditioner 2, which then performs the corresponding operation according to the control instructions.

[0129] In another embodiment, the air conditioner and the fresh air device are two independent devices, and the air conditioner and the fresh air device can exchange data with the server through network communication.

[0130] It should be noted that the server 1 in the embodiment of the present invention can be a smart home server in a local network or a smart home server in the cloud. The network communication method is not limited to Wi-Fi network, but can also adopt a combination of one or more of wired network, other short-range wireless networks (such as ZigBee network, Lora network, etc.), and public data network (such as 4G, 5G network, etc.). The specific server location and data communication network form can be selected by those skilled in the art according to the actual situation.

[0131] Furthermore, the present invention also provides an air conditioner, which includes a processor and a memory. The memory can be configured to store an air conditioning control method for executing the above method embodiment, and the program can be loaded and run by the processor to implement the above air conditioning control method.

[0132] In one embodiment, the air conditioner is preferably a fresh air air conditioner with a built-in fresh air function. The fresh air air conditioner exchanges data with a smartwatch and an infrared skin temperature detection device via wireless communication such as Wi-Fi or Bluetooth to obtain the user's blood oxygen saturation and skin temperature.

[0133] In another embodiment, the air conditioner is a fresh air air conditioner with a built-in fresh air function, and the fresh air air conditioner is also equipped with a built-in infrared body surface temperature detection module.
