All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. And can be modified as needed by those skilled in the art to suit particular applications.
Referring to fig. 1, fig. 1 is a flowchart illustrating main steps of an air conditioner control method according to an embodiment of the present invention. The air conditioner control method of the embodiment of the invention comprises the following steps:
step S1: acquiring the blood oxygen saturation and the body surface temperature of a user;
step S2: and controlling an environment temperature adjusting function and/or a fresh air function based on the blood oxygen saturation and the body surface temperature difference.
In step S1, in the embodiment of the present invention, the blood oxygen saturation of the user is acquired through the smart band. It should be noted that the blood oxygen saturation level of the user can also be obtained through other intelligent wearable devices, such as an intelligent bracelet, an intelligent ring, a finger clip oximeter, and the like. Or the blood oxygen saturation level of the user is acquired by other blood oxygen saturation level detection devices as long as the device has a data communication function and the blood oxygen saturation level data can be acquired by other devices.
In the embodiment of the invention, the body surface temperature of the user is measured by the infrared body temperature detection device which is arranged on the air conditioner or independently arranged. Meanwhile, the infrared body temperature detection device can also be used for detecting whether a person exists in the air-conditioning action area, and the control method of the step S2 can be triggered to enable the air-conditioning action area when the fact that the person exists in the air-conditioning action area is detected.
In the embodiment of the invention, the air conditioner working mode controlled according to the method of the invention is called an intermittent autonomous temperature control mode. The user can set a method for the air conditioner to enter the intermittent automatic temperature control mode according to actual conditions, for example, the selection can be directly performed through an air conditioner remote controller, or the selection can be triggered through a certain condition, such as the aforementioned triggering mode through the infrared body temperature detection device.
Next, a detailed step flow of step S2 will be described with reference to fig. 2 and 3. In the embodiment of the present invention, preferably, the air conditioner is a fresh air conditioner having a fresh air function; meanwhile, an infrared body temperature detection device is arranged in the air conditioner, and the air conditioner controller can detect whether a user is in the working area of the air conditioner and the body surface temperature of the user through the infrared body temperature detection device; in addition, the air conditioner can acquire the blood oxygen saturation data of the user acquired by the intelligent wearable device in a Wi-Fi (wireless fidelity), bluetooth or other wireless communication modes; the air conditioner control method is realized by an air conditioner controller.
Fig. 2 is a detailed process flow of step S2 when the air conditioner is in the cooling mode.
In step S100, the air conditioner operates in the cooling mode, the air conditioner is set to automatically enter the intermittent autonomous temperature control mode after detecting that the person enters the room, and the air conditioner enters the intermittent autonomous temperature control mode after detecting that the person enters the room by the infrared body temperature detection device built in the air conditioner.
In step S101, after the air conditioner enters the intermittent autonomous temperature control mode, it is first determined whether the blood oxygen saturation level of the user is greater than or equal to a first blood oxygen saturation level threshold.
It should be noted that the blood oxygen saturation is the percentage of the volume of oxygenated hemoglobin bound by oxygen in the blood to the total available hemoglobin volume, i.e. the concentration of blood oxygen in the blood, which is an important physiological parameter of the respiratory cycle. Thus, detecting arterial oxygen saturation allows an estimate of the oxygenation of the lungs and the hemoglobin oxygen carrying capacity. When the blood oxygen saturation is low and normal, the normal metabolism of cells can be directly influenced, and the human life can be seriously threatened. In the embodiment of the present invention, the blood oxygen saturation is taken as the blood oxygen saturation of arterial blood, and the normal value of the blood oxygen saturation of arterial blood is usually not less than 95% for most people. Thus, the first blood oxygen saturation threshold may be set at 95%.
When the blood oxygen saturation level is greater than or equal to the first blood oxygen saturation level threshold, step S102 is executed. In step S102, the blood oxygen saturation level of the user is at a normal level, and therefore, the fresh air function is not required to be started, and only the refrigeration function is started, so that the indoor actual ambient temperature reaches the ambient temperature preset by the user. After the current state continues to run for the first duration, step S104 is executed to continue to determine the blood oxygen saturation level of the user.
When the blood oxygen saturation level is less than the first blood oxygen saturation level threshold, step S103 is executed. In step S103, the blood oxygen saturation level of the user is lower than the normal level, so that the oxygen content in the indoor air can be increased by turning on the fresh air function, thereby improving the blood oxygen saturation level of the body of the user. After the current state continues to run for the second duration, step S104 is executed to continue to determine the blood oxygen saturation level of the user.
In step S104, a body surface temperature sampling timing is set, the body surface temperature of the user is acquired, and it is continuously determined whether the blood oxygen saturation level of the user is greater than or equal to the first blood oxygen saturation level threshold.
When the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S105 is performed. In step S105, considering that the air-conditioning cooling has been operated for a period of time, the ambient temperature is usually near the room temperature set by the user, and at this time, in consideration of energy saving, the air-conditioning compressor is turned off, cooling is suspended, but the air-conditioning continues to supply air, so that the cooling effect before the air-conditioning can still be circulated throughout the room, and thus, while the air-conditioning saves energy, the change of the ambient temperature can be reduced, and the comfort level of the user can be improved. And, the user's blood oxygen saturation is at normal level, therefore closes the new trend function. After the current state continues to operate for the third duration, step S107 is performed to determine the change of the body surface temperature.
When the blood oxygen saturation level is less than the first blood oxygen saturation level threshold, step S106 is performed. In step S106, the air conditioner compressor is turned off, cooling is suspended, and air conditioning is performed for the same reason as in step S105; at the moment, the blood oxygen saturation of the user is lower than the normal level, and the fresh air function is started. After the current state continues to operate for the fourth duration, step S107 is performed to determine the change in the body surface temperature.
In step S107, a body surface temperature sampling time is also set, the body surface temperature at the current time is collected, and the difference between the body surface temperature of the user at the current time and the body surface temperature at the previous sampling time is calculated to obtain the body surface temperature difference. And judging whether the body surface temperature difference is greater than a body surface temperature difference threshold value.
When the air conditioner works in a refrigeration mode, the body surface temperature difference = the current body surface temperature-the body surface temperature at the previous moment, 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 at 0.5 ℃.
It should be noted that, the body surface temperature difference is adopted as the basis for controlling the indoor temperature of the air conditioner, because the body surface temperature difference can reflect the variation trend of the indoor environment temperature, and the body surface temperature difference is controlled to change in a smaller range, the comfort level of the user can be improved. Meanwhile, the control difference caused by the difference of the basal body temperature of the user can be eliminated, and the applicability and the accuracy of the control method are improved.
When the body surface temperature difference is larger than the body surface temperature difference threshold value, step S108 is executed to further determine the blood oxygen saturation level of the user.
If the body surface temperature difference is greater than the body surface temperature difference threshold value and the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold value, step S109 is performed. In step S109, it can be known from the calculation method of the body surface temperature difference that the body surface temperature is in an increasing trend, the human body feels hot, the trend of the ambient temperature change is also hot, the refrigeration function can be turned on at this time, the ambient temperature is reduced, and the body surface temperature of the user is also reduced, so that the user is in an environment with comfortable body feeling. At this time, the blood oxygen saturation of the user is at a normal level, and thus the fresh air function is turned off. And after the current state continuously runs for the fifth duration, returning to execute the step S104, and circularly and continuously controlling the refrigeration function and/or the fresh air function according to the body surface temperature difference and the blood oxygen saturation.
If the body surface temperature difference is larger than the body surface temperature difference threshold value and the blood oxygen saturation level is smaller than the first blood oxygen saturation level threshold value, step S110 is executed. In step S110, the cooling function may be turned on for the same reason as in step S109. Meanwhile, the blood oxygen saturation of the user is lower than the normal level, so that the fresh air function is started. And after the current state continuously runs for the sixth duration, returning to execute the step S104, and circularly and continuously controlling the refrigeration function and/or the fresh air function according to the body surface temperature difference and the blood oxygen saturation.
When the body surface temperature difference is less than or equal to the body surface temperature difference threshold, step S111 is executed to continue further determining the blood oxygen saturation level of the user.
If the body surface temperature difference is less than or equal to the body surface temperature difference threshold value and the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold value, step S112 is executed. In step S112, at this time, since the body surface temperature difference is not changed greatly, or the body surface temperature of the user is lower than the previous time, it indicates that the cooling capacity of the air conditioner can meet or exceed the requirement of the ambient temperature control, and for the same energy-saving reason as that in step S105, the air conditioner compressor is turned off, the cooling is suspended, and the air conditioner supplies air; meanwhile, the blood oxygen saturation of the user is at a normal level, so the fresh air function is turned off. And after the current state continuously runs for the seventh duration, returning to execute the step S107, and circularly and continuously controlling the refrigeration function and/or the fresh air function according to the body surface temperature difference and the blood oxygen saturation.
If the body surface temperature difference is less than or equal to the body surface temperature difference threshold value and the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold value, step S113 is performed. In step S113, for the same energy saving reason as in step S112, the air conditioner compressor is turned off, cooling is suspended, and air conditioning blowing is performed; meanwhile, the blood oxygen saturation of the user is lower than a normal level, so that the fresh air function is started. And after the current state continuously runs for the eighth duration, returning to execute the step S107, and circularly and continuously controlling the refrigeration function and/or the fresh air function according to the body surface temperature difference and the blood oxygen saturation.
The current time of the sampling time of the body surface temperature for calculating the body surface temperature difference is fixed to be the time of S107 at which the body surface temperature difference needs to be judged; at the previous moment, the steps executed by the air conditioner are different due to different real-time detected personnel states, so that the previous moment is also changed. For example, the time immediately before the first calculation of the body surface temperature in the intermittent autonomous temperature control mode is the execution of step S104, and the time interval at this time is the third duration or the fourth duration. In the continuous control process, after the step S112 or S113 is executed, the process returns to the step S107, and the body surface temperature of the body surface temperature difference is calculated as the body surface temperature data obtained when the step S107 is executed twice.
Continuing to read fig. 3, fig. 3 is a detailed step flow of step S2 when the air conditioner is in the heating mode.
In step S200, the air conditioner operates in the heating mode, and the air conditioner is manually set by the user to enter the discontinuous autonomous temperature control mode.
In step S201, after the air conditioner enters the intermittent autonomous temperature control mode, it is first determined whether the blood oxygen saturation level of the user is greater than or equal to a first blood oxygen saturation level threshold.
When the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S202 is performed. In step S202, the blood oxygen saturation level of the user is at a normal level, and therefore, the heating function is only turned on without turning on the fresh air function, so that the indoor actual ambient temperature reaches the ambient temperature preset by the user. After the current state continues to run for the 1 st duration, step S204 is executed to continue to determine the blood oxygen saturation level of the user.
When the blood oxygen saturation level is less than the first blood oxygen saturation level threshold, step S203 is executed. In step S203, the blood oxygen saturation level of the user is lower than the normal level, so that the oxygen content in the indoor air can be increased by turning on the fresh air function, thereby improving the blood oxygen saturation level of the body of the user. After the current state continues to run for the 2 nd duration, step S204 is executed to continue to determine the blood oxygen saturation level of the user.
In step S204, a body surface temperature sampling timing is set, the body surface temperature of the user is acquired, and it is continuously determined whether the blood oxygen saturation level of the user is greater than or equal to the first blood oxygen saturation level threshold.
When the blood oxygen saturation is greater than or equal to the first blood oxygen saturation threshold, step S205 is performed. In step S205, considering that the air conditioner has been operated for a period of time, the ambient temperature is usually near the room temperature set by the user, and at this time, the air conditioner compressor is turned off to suspend heating in view of energy saving, but the air conditioner continues to supply air, so that the heating effect before the air conditioner can still be circulated throughout the room, and the change of the ambient temperature can also be reduced, thereby improving the comfort of the user. And, the user's blood oxygen saturation is at normal level, therefore closes the new trend function. After the current state continues to run for the 3 rd duration, step S207 is executed to determine the change of the body surface temperature.
When the blood oxygen saturation level is less than the first blood oxygen saturation level threshold, step S206 is performed. In step S206, the air-conditioning compressor is turned off, heating is suspended, and air-conditioning blowing is performed for the same reason as in step S205; at the moment, the blood oxygen saturation of the user is lower than the normal level, and the fresh air function is started. After the current state continues to run for the 4 th duration, step S207 is executed to determine the change of the body surface temperature.
In step S207, a body surface temperature sampling time is also set, the body surface temperature at the current time is collected, and the difference between the body surface temperature of the user at the current time and the body surface temperature at the previous sampling time is calculated to obtain the body surface temperature difference. And judging whether the body surface temperature difference is greater than a body surface temperature difference threshold value.
When the air conditioner works in a heating mode, the body surface temperature difference = the body surface temperature at the previous moment-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 ℃.
When the body surface temperature difference is larger than the body surface temperature difference threshold value, step S208 is executed to further determine the blood oxygen saturation level of the user.
If the body surface temperature difference is greater than the body surface temperature difference threshold value and the blood oxygen saturation level is greater than or equal to the first blood oxygen saturation level threshold value, step S209 is performed. In step S209, the calculation method of the body surface temperature difference indicates that the body surface temperature is in a downward trend, the human body feels cold, the trend of the environmental temperature change is also in a cold trend, the heating function can be turned on, and when the environmental temperature is increased, the body surface temperature is also increased, so that the user is in an environment with comfortable body feeling. Meanwhile, the blood oxygen saturation of the user is at a normal level, so that the fresh air function is closed. And after the current state continuously runs for the 5 th duration, returning to execute the step S204, and circularly and continuously controlling the refrigeration function and/or the fresh air function according to the body surface temperature difference and the blood oxygen saturation.
If the body surface temperature difference is larger than the body surface temperature difference threshold value and the blood oxygen saturation is smaller than the first blood oxygen saturation threshold value, step S210 is executed. In step S210, the cooling function may be turned on for the same reason as in step S209. Meanwhile, the blood oxygen saturation of the user is lower than the normal level, so that the fresh air function is started. And after the current state continuously runs for the 6 th duration, returning to execute the step S204, and circularly and continuously controlling the refrigeration function and/or the fresh air function according to the body surface temperature difference and the blood oxygen saturation.
When the body surface temperature difference is less than or equal to the body surface temperature difference threshold, step S211 is executed, and the blood oxygen saturation level of the user is further determined as well.
If the body surface temperature difference is less than or equal to the body surface temperature difference threshold value and the blood oxygen saturation level is greater than or equal to the first blood oxygen saturation level threshold value, step S212 is executed. In step S212, at this time, since the body surface temperature difference is not changed greatly or the body surface temperature of the user is higher than the previous time, it is described that the heating capacity of the air conditioner can meet or exceed the requirement of the environmental temperature control, and for the same energy-saving reason as that in step S205, the compressor of the air conditioner is turned off, heating is suspended, and air supply of the air conditioner is performed; meanwhile, the blood oxygen saturation of the user is at a normal level, so the fresh air function is turned off. And after the current state continuously runs for the 7 th duration, returning to execute the step S207, and circularly and continuously controlling the refrigeration function and/or the fresh air function according to the body surface temperature difference and the blood oxygen saturation.
If the body surface temperature difference is less than or equal to the body surface temperature difference threshold value and the blood oxygen saturation level is greater than or equal to the first blood oxygen saturation level threshold value, step S213 is performed. In step S213, for the same energy saving reason as in step S212, the air conditioner compressor is turned off, heating is suspended, and air conditioning is performed; meanwhile, the blood oxygen saturation of the user is lower than the normal level, so that the fresh air function is started. And after the current state continuously runs for the 8 th duration, returning to execute the step S207, and circularly and continuously controlling the refrigeration function and/or the fresh air function according to the body surface temperature difference and the blood oxygen saturation.
It should be noted that the current time in the sampling time of the body surface temperature for calculating the body surface temperature difference is fixed to the time of S207 at which the body surface temperature difference needs to be determined; and the previous time is different according to different steps executed by the air conditioner control. For example, the time immediately before the first calculation of the body surface temperature in the intermittent autonomous temperature control mode is the time when step S204 is executed, and the time interval at this time is the third duration or the fourth duration. In the continuous control process, after the step S212 or S213 is executed, the process returns to the step S207, and the body surface temperature of the body surface temperature difference is calculated as the body surface temperature data obtained when the step S207 is executed twice.
It should be noted that the settings of the first duration to the eighth duration when the air conditioner operates in the cooling mode may all be the same, may be different from each other, or may be partially the same; similarly, the settings of the 1 st duration to the 8 th duration when the air conditioner operates in the heating mode may be all the same, may be different from each other, or may be partially the same. The user can set according to actual conditions such as air conditioner power, new trend power, room condition. As an example, the first duration and the second duration may be determined according to a maximum time required for the actual ambient temperature to reach the ambient temperature preset by the user in the cooling mode after the air conditioner enters the intermittent autonomous temperature control mode.
As an example, when the air conditioner operates in the cooling mode, the first duration and the second duration may be set to 60 minutes as well; the third duration and the fourth duration may be set to 30 minutes as well; the fifth duration and the sixth duration may likewise be set to 25 minutes; the seventh duration and the eighth duration may likewise be set to 25 minutes.
As an example, when the air conditioner operates in the heating mode, the 1 st duration and the 2 nd duration may be equally set to 60 minutes; the 3 rd and 4 th durations may be set to 30 minutes as well; the 5 th and 6 th durations may be set to 25 minutes as well; the 7 th and 8 th durations may be set to 25 minutes as well.
It should be noted that, when acquiring the blood oxygen saturation and the body surface temperature difference data of a plurality of users in the air conditioner action area, for the blood oxygen saturation, in consideration of health priority, the data with the lowest blood oxygen saturation in all the users can be selected as the control basis of the invention, so as to ensure that the blood oxygen saturation of all the indoor people is at the normal level and the health is priority as much as possible; for the body surface temperature difference, the average value of the body surface temperature difference of all the people can be selected, and the requirement of most people on the environment temperature can be met. The effective blood oxygen saturation and body surface temperature difference data of multiple users can be determined by other schemes according to actual conditions by persons skilled in the art.
After the fresh air function is started, the gear of the fresh air supply can be controlled according to the data of the oxyhemoglobin saturation of the user, and when the oxyhemoglobin saturation is reduced, the gear of the fresh air supply is correspondingly improved. As an example, when the blood oxygen saturation is greater than 93%, the fresh air supply gear is set to a low gear; when the blood oxygen saturation is greater than 90% but less than or equal to 93%, the fresh air supply gear is set as a middle gear; when the blood oxygen saturation is less than 90%, the fresh air supply gear is set to be a high gear.
And when the blood oxygen saturation is low for a long time, the body of the person is possibly in an unhealthy state, so that when the duration that the blood oxygen saturation of the user is lower than the second blood oxygen saturation threshold is longer than the blood oxygen alarm time threshold, alarm prompt information can be sent to an intelligent terminal designated by the user to remind the related person that the blood oxygen saturation of the user in the air-conditioning room is low continuously, and the person can check the reason timely. Since the second blood oxygen saturation threshold is the blood oxygen saturation value when the oxygen content in the blood of the user is low, the second blood oxygen saturation threshold is smaller than the first blood oxygen saturation threshold. As an example, the second blood oxygen saturation threshold may be set to 90% and the blood oxygen alarm time threshold may be set to 2 hours. Other values can be set by those skilled in the art according to the actual situation.
