It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The return air temperature of the air conditioner in the sleep state is obtained, and the return air temperature is detected by the temperature sensor. When the user in the room where the air conditioner is in the sleep state, the infrared resistance device obtains the thermal resistance information of the mattress system in the room under the sleep state (the thermal resistance reference value is set, which is different in different seasons, for example, Rt in summer, In the winter, it is RT, etc., or different thermal resistance reference values are set according to different air conditioner operating modes). The sleep state may be after the user falls into sleep for 30 minutes or after 40 minutes, the user falls asleep to detect the light intensity in the room, and the light intensity value is less than the preset light intensity value (the room is dark, the light is not turned on, no other The brightness of the device is turned on, or the value set according to the user's needs. It can also be the time to record the sleep state of each user in the most recent period (5 days or 7 days, etc.), according to the recorded time to the user. The time required to enter sleep at a time to determine whether the user has entered sleep, or obtain the current body state information of the user, and calculate the time when the user enters sleep according to the body state information combined with the age of the user, for example, when in a cold state, enter Sleep is slower; when you are tired or tired, go to sleep faster. The mattress system is a bedding covering the user on the quilt. The thermal resistance information of the mattress system is related to the thickness of the covered article. The thicker the thermal resistance, the thinner the thermal resistance is.

Step S20, calculating a thermal sensation state according to the thermal resistance information and the user body surface temperature or the return air temperature of the air conditioner;

After obtaining the thermal resistance information of the mattress system in the room under the sleep state and the user body surface temperature or the return air temperature of the air conditioner, according to the thermal resistance information and the user body surface temperature or the return air of the air conditioner The temperature is calculated for the thermal sensation state. The thermal resistance and the user's body surface temperature and the return air temperature of the air conditioner correspond to a calculation coefficient corresponding to the thermal sensation, and the calculation coefficient of the thermal resistance and the user's body surface temperature is a set value or an experimental result, and the sleep is obtained. In the state, the thermal resistance information of the mattress system in the room and the temperature of the user's body surface are calculated according to the corresponding calculation coefficient. The specific calculation process is: determining the thermal resistance information and the user body surface temperature Corresponding calculation coefficient of the thermal sensation state; calculating the thermal sensation state according to the thermal resistance information and the user body surface temperature and the corresponding calculation coefficient. The first calculation method: first calculating a first result according to the thermal resistance information and the corresponding calculation coefficient, and then calculating a second result according to the user body surface temperature and the corresponding calculation coefficient, combining the first result with the second result The preset proportional coefficient is calculated to obtain the state of cold and heat, and the proportional coefficient is set value or experimentally obtained. Or, the second calculation method: first calculating a first result according to the thermal resistance information and the corresponding calculation coefficient, and then calculating a second result according to the user body surface temperature and the corresponding calculation coefficient, that is, respectively passing the thermal resistance The information and the user's body surface temperature are calculated to obtain two cold and hot state, and the two are superimposed to obtain the user's cold and hot state. In another embodiment of the present invention, a relationship table between the thermal resistance information and the thermal sensation state and a relationship table between the user's body surface temperature and the thermal sensation state may be established in advance, and the obtained thermal resistance information and the user body are obtained. The table temperature look-up table is in a state of cold and heat. After obtaining the thermal resistance information of the mattress system in the room and the return air temperature of the air conditioner in the sleep state, the thermal sensation state is calculated according to the thermal resistance information and the return air temperature of the air conditioner. Specifically, referring to FIG. 2, the calculating the thermal sensation state according to the thermal resistance information and the return air temperature of the air conditioner includes:

Step S21, determining a wind file of the indoor fan of the air conditioner and determining an area where the user is located;

Step S22, determining a thermal sensation temperature according to the windshield, the area, and the return air temperature of the air conditioner;

FIG. 3 is a schematic diagram of the positional parameter of the array type infrared sensor module for measuring the human body in the up and down direction. In the figure, 1 is an air conditioner, 2 is an array type infrared sensor module installed on the air conditioner, and 3 is a position of the human body. 4 is the wall around the room, 5 is the ground, the array type infrared sensor module can detect the angle between the connection between the up and down direction and the human body position and the wall surface fixed by the air conditioner in which the array type infrared sensor module is installed, that is, The angle θ between the line L of the array type infrared sensor module and the human body position and the line H parallel to the wall surface of the fixed air conditioner is also a fixed value because the installation height of the air conditioner is the H in the figure. For a fixed value, the value can be obtained by the user inputting the height of the air conditioner after installation into the control interface of the air conditioner, or can be roughly estimated, so that the value of the angle θ can be calculated by the trigonometric function formula. Get the size of W: W = H * tan θ, that is, the shortest distance W value of the position of the human body relative to the air conditioner in the ground direction is obtained.

Figure 4 is a schematic diagram showing the positional parameters of the human body in the left and right direction of the array type infrared sensor module. In the figure, 1 is an air conditioner, 2 is an array type infrared sensor module mounted on the air conditioner, 3 is a human body, 4 is The walls around the room, A1 and A2 are the different locations where the human body is located. The maximum viewing angle of the array type infrared sensor module that can scan and detect the surrounding environment and objects in the left and right direction is fixed, as shown by the L1 and L4 lines in the figure. The angle b3 is the maximum angle of view of the array type infrared sensor module in the left and right direction to detect the surrounding environment and objects. When people are in different positions in the room, as shown in the figure A1 and A2, they are at the maximum angle of view. The position of the range in the left-right direction can be detected by the array type infrared sensor module. Since L1 and L4 are fixed, the line between the human body and the array type infrared sensor module and the angle between the two sides can be detected. If the human body is located at the A1 point position, the size of the angle b1 between the connection line L2 and L1 determined by the human body and the array type infrared sensor module can be detected, and the human body position is the same. At the A2 point position, the size of the angle b2 between the line L3 and L1 determined by the human body and the array type infrared sensor module can be detected. In this way, the position of the human body in the left-right direction of the array type infrared sensor module can be determined by the angles of the angles b1 and b2. Of course, the angle is not necessarily fixed, and the line formed by the human body and the array type infrared sensor module is formed by the left line L1 of the maximum angle of view. The angle may also be the angle formed by the line defined by the human body and the array type infrared sensor module and the right line L2.

The above-mentioned array type infrared sensor module measures the positional parameter of the human body in the up and down direction and the positional parameter of the human body in the left and right direction to determine the position of the human body in the room. Since the scanning distance and the angle are fixed, it can be calculated. The specific location of the human body in the room. After determining the position of the human body in the room, and then determining the running wind speed value of the position of the human body according to the position of the human body in the room and the running speed of the air conditioner. According to the experiment, when the position of the human body is closer to the position where the air conditioner is located, the difference between the running wind speed of the position of the human body and the running wind speed of the air conditioner is smaller; when the position of the human body is farther away from the air conditioner When facing the position, the difference between the running wind speed of the position where the human body is located and the operating wind speed of the air conditioner is greater.

Specifically, determining the operating wind speed value of the location of the human body may include the following steps:

Dividing the air blowing area of the air conditioner into a plurality of sub-areas in advance;

As shown in FIG. 5, the area in the room can be divided into 5 sub-areas from A to E, wherein the C area is an area relatively close to the position of the air conditioner.

Obtaining the operating wind speed of the air conditioner;

The operating wind speed value of the air conditioner can be divided into several levels, that is, the wind speed level V2 value, and each wind speed level V2 has a corresponding running wind speed value. This level can be the operating windshield of the air conditioner, such as high, medium, low, and the like. According to the operating windshield of the air conditioner, the operating wind speed value of the air conditioner can be obtained.

Obtain the sub-area to which the human body is located;

Through the positional parameters measured by the infrared array sensor module and the pre-divided sub-areas, it can be obtained in which sub-area the human body is located, that is, the sub-area to which the human body is located. For example, if the human body is in the right position of the air conditioner, the human body is located in the C area.

According to the operating wind speed of the air conditioner and the sub-area to which the human body is located, the running wind speed value of the position of the human body is determined.

In this embodiment, according to the relationship between the running wind speed of the position of the human body and the running speed of the air conditioner, the running wind speed value V1 when the human body is located in different regions can be determined, for example:

According to the experiment, when the position of the human body is closer to the position where the air conditioner is located, the difference between the running wind speed of the position of the human body and the running wind speed of the air conditioner is smaller; when the position of the human body is farther away from the air conditioner When facing the position, the difference between the running wind speed of the position where the human body is located and the operating wind speed of the air conditioner is greater. As can be seen from the above table, the C area is the area closest to the position of the air conditioner, and the human body is located in the C area. The running wind speed value is the largest, and the A, B, D, and E areas are far away from the C area near the position where the air conditioner is facing, and the running wind speed value is relatively reduced when the human body is located in the two areas. Different wind speeds will affect the temperature of the heat and cold. For the body, refer to Table 1 below, which is the mapping table of the windshield, the area where the person is located and the temperature of the cold and the heat in the cooling mode. The T1 in the table is the return air temperature of the air conditioner, and T1a, T3a and T4a are the cold of the human body in different areas. The thermal temperature, Table 2 is the mapping table of the wind file, the area where the person is located and the temperature of the heat and cold in the heating mode. 1 corresponds to A, 2 corresponds to B, 3 corresponds to C, 4 corresponds to D, and 5 corresponds to E. In the embodiment, in the cooling or heating mode, the temperature of the cold and the heat is obtained by combining the windshield and the area where the person is located, the accuracy of the cold and hot state of the human body is improved, and the comfort of the air conditioner is improved. The area where the human body is located is different, the wind file is different, and the correction corresponding to the different T1 is correct. According to the correction value, the temperature T1 of the different regions of the human body can be obtained by correcting the T1.

The thermal resistance message and the thermal sensation temperature respectively have a calculation coefficient corresponding to the thermal sensation, and the calculation coefficient of the thermal resistance message and the thermal sensation temperature is a set value or an experimental result, and the bed in the room is obtained when the sleep state is obtained. The thermal resistance information of the system and the thermal sensitivity temperature are calculated according to the corresponding calculation coefficients. The first calculation method: firstly calculating a first result according to the thermal resistance information and the corresponding calculation coefficient, and then calculating a second result according to the thermal sensible temperature and the corresponding calculation coefficient, combining the first result with the second result The preset proportional coefficient is calculated to obtain the state of cold and heat, and the proportional coefficient is set value or experimentally obtained. Or, the second calculation method: first calculating a first result according to the thermal resistance information and the corresponding calculation coefficient, and then calculating a second result according to the thermal sensible temperature and the corresponding calculation coefficient, that is, respectively passing the thermal resistance The information and the thermal sensation temperature are calculated to obtain two thermal sensations, and the two are superimposed to obtain the user's thermal sensation state. In another embodiment of the present invention, it is also possible to establish a relationship table between the thermal resistance information and the thermal sensation state in advance, and a relationship table between the thermal sensation temperature and the thermal sensation state, and the calculated thermal resistance information and the hot and cold heat. The temperature-sensing table looks hot and cold.

Further, in order to ensure the accuracy of the calculated thermal sensation state, when the calculated value of the thermal sensation state is greater than the first preset value, the value of the thermal sensation state takes a first preset value; When the value of the sense state is less than the second preset value, the value of the cold heat sense state takes a second preset value, and the first preset value is greater than the second preset value. The first preset value may be 3 or 4, etc., and the second preset value may be -3 or -4 or the like.

The state of cold and heat of the human body in sleep state can be reflected by specific different values, as shown in the following table:

冷热感状态值Cold and heat state value	冷热感区间Cold and hot zone	热舒适感Thermal comfort
-3≤PMV<-2-3≤PMV<-2	区间8Interval 8	冷cold
-2<PMV≤-1-2<PMV≤-1	区间7Interval 7	有点冷a little cold

1<PMV≤21<PMV≤2	区间2Interval 2	有点热A little hot
2<PMV≤32<PMV≤3	区间1 Interval 1	热heat

In the above table, the size of the thermal and thermal state value M is divided into eight sections, which respectively represent different cold/hot comfort feelings of the human body.

Step S30, controlling the operation of the air conditioner according to the state of the thermal sensation.

According to the state of the cold and hot state of the human body, the operating parameters of the air conditioner are controlled to change the state of the cold and hot state of the human body to a comfortable interval, and the operating parameters of the air conditioner include one of a set temperature, a running wind speed, and a wind guiding strip state. Kind or more. For example, the current state of the human body's thermal sensation is 2.5. It is in the interval 1 and is in a hot feeling. The compressor frequency and the indoor fan windshield are adjusted by automatically reducing the set temperature of the air conditioner (reducing the compressor frequency and reducing the indoor fan windshield) The magnitude of the decrease corresponds to the value of the set temperature adjustment) so that the ambient temperature in the room is lowered, so that the value of the person's thermal sensation state is gradually decreased, and finally maintained in the interval 4, so that the state of the human body heat and cold is changed to Comfortable state.

According to the air conditioner control method of the present invention, the thermal resistance state is calculated by the thermal resistance information of the mattress system in the sleep state and the user body surface temperature or the return air temperature of the air conditioner, and further according to the heat and cold. The sense state controls the operation of the air conditioner. Effectively avoid the current air conditioner control process, can not provide accurate user hot and cold state, according to this accurate hot and cold state to control the operation of the air conditioner. Accurately provide the user's cold and hot state, thereby improving the accuracy of the air conditioner control and improving the comfort of the air conditioner.

Air conditioners include a variety of operating modes, such as cooling or heating. In winter, the weather is cold and will run in heating mode.
