Figure 1 is a schematic flowchart of the wind speed control method of an indoor unit provided by this application. As shown in Figure 1, the wind speed control method of an indoor unit provided by the embodiment of the present application includes: Step 101: Determine the individual movement rate of each individual in the room based on the behavioral information fed back by the radar module.

It should be noted that the execution subject of the wind speed control method of the indoor unit provided by the embodiment of the present application is the wind speed control device of the indoor unit.

The application scenario of the wind speed control method of the indoor unit provided by the embodiment of the present application is that after the user activates the air conditioner, the individual's activity level is determined through the behavioral information fed back in real time by the radar module, so as to adjust the fan speed of the indoor unit to ensure that the exhaust gas is discharged. The air volume matches the amount of activity.

Among them, the radar module periodically collects relevant behavioral information of all individuals in the room at specified time intervals, and sends the behavioral information to the wind speed control device of the indoor unit. The embodiments of this application do not specifically limit the working cycle of the radar module.

Optionally, the radar module can perform collection operations in the default working cycle.

Optionally, the user can issue a cycle change command, so that the radar module receives and responds to the command and changes the working cycle to the cycle indicated by the command to perform the collection operation.

It should be noted that before step 101, the user needs to send an activation command through the transmission medium to activate the working mode of the air conditioner, so that the indoor unit of the air conditioner runs at the default wind speed of this mode, and the outdoor unit runs at the default frequency of this mode. .

Optionally, the user can transmit activation instructions through the control device and use wireless communication between the control device and the air-conditioning system to initialize the working mode of the air-conditioning system.

Optionally, the user can issue an activation instruction through voice interaction, and the air conditioning system receives the activation instruction, performs voice recognition, and initializes the working mode.

Specifically, in step 101, after the air conditioner starts the working mode, the wind speed control device of the indoor unit controls to receive the behavioral information collected by the radar module in real time for each individual in the room, and to facilitate The individual movement rate of each individual is calculated using the real-time behavioral information of each individual.

The embodiments of this application do not specifically limit the type and quantity of radar sensing devices in the radar module.

For example, the radar module may include a lidar, infrared sensor, etc.

Optionally, since the horizontal detection range of millimeter wave radar can reach ±75°, the vertical detection range is ±40°, the detection distance can reach 8 meters, the distance output accuracy can reach 0.1 meters, and the angle output accuracy can reach 1°, and It does not involve privacy issues, is not affected by light, and its response speed is also faster.

Therefore, the wind speed control device of the indoor unit uses the heart rate information collected in real time by the millimeter wave radar as the current heart rate of the individual user.

For example, the radar module may include a variety of sensing elements such as millimeter wave radar, lidar, and infrared sensors. The wind speed control device of the indoor unit integrates the behavioral information collected by each sensing element to comprehensively depict the Current individual movement rate.

For example, millimeter wave radar can be used to collect individual heart rate information, and the movement rate corresponding to the current heart rate information can be obtained based on the mapping relationship between heart rate information and movement rate fitted from a large amount of prior data.

Step 102: Obtain the first target wind speed gear corresponding to each first target sub-interval according to the first target sub-interval corresponding to each individual's movement rate.

Among them, the target sub-interval is obtained by dividing the corresponding rate interval when the individual displacement occurs.

It should be noted that the wind speed control device of the indoor unit pre-sets N ₁ points in the speed interval corresponding to when the individual displacement occurs, and divides it into N ₁ +1 sub-intervals.

Among them, N ₁ is a positive integer greater than or equal to 1. Each sub-interval is correspondingly set with a different first target wind speed gear. Moreover, the first target wind speed gear increases as the upper limit value of its corresponding sub-interval is closer to the maximum movement rate.

Specifically, in step 102, the wind speed control device of the indoor unit uses the sub-interval where the individual movement rate of each individual is located as the first target sub-interval, and obtains the first target wind speed gear corresponding to the sub-interval.

The embodiments of this application do not specifically limit the division of sub-intervals and the setting of corresponding wind speed gears. For example, taking N ₁ equal to 4 as an example, the corresponding rate interval (in meters per second) when the human body is displaced can be divided into five sub-intervals, namely [0,0.5), [0.5,1), [1,1.5), [1.5,2) and [2,+∞), where:

If the individual movement rate of an individual is [0,0.5), that is, the individual will be in a static state due to factors such as sleep or the inability to move on its own. Since the amount of activity in this state approaches 0, the corresponding The wind speed gear is set to the silent gear with the lowest wind speed, and the fan speed value corresponding to the silent gear can be 500 revolutions per minute (r/min).

If the individual movement rate of an individual is [0.5,1), that is, the individual is in a slow moving state. Since the amount of activity in this state is particularly small, the corresponding wind speed gear needs to be set to a low speed gear with a lower wind speed. , and the fan speed value corresponding to the low speed gear can be 660r/min.

If the individual movement rate of an individual is [1,1.5), that is, the individual is in a normal walking state, the corresponding wind speed gear needs to be set to a medium speed gear with a relatively normal wind speed, and the corresponding wind speed gear The fan speed value can be 740r/min.

If the individual movement rate of an individual is [1.5, 2), that is, the individual is in a fast walking state. Since the amount of activity in this state is large, the corresponding wind speed gear needs to be set to a higher wind speed. High speed gear, and the fan speed value corresponding to the high speed gear can be 850r/min.

If the individual movement rate of an individual is [2,+∞), that is, the individual is in a running state. Since the amount of activity in this state is particularly large, the corresponding wind speed gear needs to be set to the powerful gear with the highest wind speed. And the fan speed value corresponding to the strong gear can be 960r/min.

It can be understood that the N ₁ points in the corresponding rate interval when the individual undergoes displacement can also be set at unequal intervals to divide multiple unequal rate sub-intervals.

Step 103: Determine the target rotation speed based on the rotation speed value corresponding to each first target wind speed gear, so as to control the indoor unit to adjust the fan rotation speed to the target rotation speed.

Specifically, in step 103, the wind speed control device of the indoor unit calculates the target speed based on the number of individuals in the room and the rotation speed value corresponding to the first target wind speed gear obtained by each individual, and encapsulates the target rotation speed in the control In the command, it is sent to the indoor unit.

The indoor unit receives and responds to the control command and adjusts the fan speed of its internal fan to the target speed.

The embodiment of the present application does not specifically limit the calculation method of the target rotation speed.

Optionally, when the wind speed control device of the indoor unit determines that there is an individual in the room based on the group number of individual movement rates, it uses the sub-interval where the individual's individual movement rate is located to obtain the wind speed gear corresponding to the sub-interval, and The speed value of this gear is used as the target speed to make the indoor unit turn the fan The rotation speed is adjusted to the target rotation speed to provide targeted air supply to the individual.

Optionally, when the wind speed control device of the indoor unit determines that there are multiple individuals in the room based on the group number of individual movement rates, the sub-interval where the individual movement rate of each individual is located is used to obtain multiple wind speed gears corresponding to different sub-intervals. Bit. Based on the principle of taking care of vulnerable groups, the weakest wind speed gear is selected for air supply, and the speed value of this gear is used as the target speed, so that the indoor unit adjusts the fan speed to the target speed to provide universal air supply to the group. wind.

The embodiment of the present application monitors the individual's motion status in real time based on the radar module, obtains the individual's motion rate, determines the corresponding wind speed gear through the sub-interval where the individual's motion rate is located, and uses the rotation speed value corresponding to the wind speed gear to convert The target speed is output for the indoor unit to adjust the fan speed. It realizes activity analysis based on individual speed changes and adaptively adjusts the wind speed of the indoor unit. According to the user's own movement, it can obtain the air volume at a positive correlation with the fan speed, improving the control accuracy and intelligence of the wind speed. , optimize user experience.

Based on any of the above embodiments, after obtaining the first target wind speed gear corresponding to each first target sub-interval according to the first target sub-interval corresponding to each individual's movement rate, it also includes: Within a certain period of time, the new individual movement rate of each individual is determined based on the reacquired behavioral information.

It should be noted that the preset duration refers to the duration for which the movement status continues to be monitored after the first target sub-interval of the individual movement rate is initially determined. The preset time is used to delay the control of the indoor unit to adjust the fan speed after the target speed is initially determined.

The embodiment of the present application does not specifically limit the value of the preset duration. For example, the preset duration may be 2 minutes.

Specifically, after step 102, the wind speed control device of the indoor unit receives the behavioral information that the radar module continuously monitors for each individual within a preset time period, and uses the behavioral information reacquired by each individual to calculate the corresponding individual The new individual movement rate at the next moment.

When it is determined that any new individual movement rate is still in the first target sub-interval corresponding to the individual movement rate, the first target wind speed gear corresponding to each first target sub-interval is obtained.

Specifically, the wind speed control device of the indoor unit compares each individual's new individual movement rate with the original interval range determined by the individual in step 102 (ie, the first target sub-interval corresponding to the individual).

If the new individual's movement rate is still within the original range of the individual, that is, the individual's The movement rate has been within the predetermined first target sub-interval for a preset period of time. If it is determined that the individual's movement state is relatively stable, the first target wind speed gear that matches the individual's activity level is determined based on the sub-interval.

If the new individual's movement rate is not within the original range of the individual, that is, the individual's movement rate changes within the preset time period, and the movement state of the individual is determined to be relatively unstable, the individual's activity level cannot be determined and needs to continue. The movement of the individual is monitored until the movement rate of the individual within the preset time period is in the same sub-interval, and then the wind speed gear that matches the amount of activity can be determined based on the sub-interval.

Specifically, the wind speed control device of the indoor unit executes the above control logic for all individuals in the room, and after obtaining the first target wind speed gear corresponding to each individual in a stable moving state, the wind speed control device controls the wind speed according to the corresponding first target wind speed gear of each individual. The speed value is calculated, the target speed is encapsulated in the control command, and sent to the indoor unit.

The embodiment of this application continuously monitors the individual's movement status in real time based on the radar module within a preset period of time, obtains the individual movement rate, and determines the wind speed gear in the stable moving state through multiple groups of individual movement rates in the same sub-interval. And use the rotation speed value corresponding to the wind speed gear to convert the target rotation speed for the indoor unit to adjust the fan rotation speed. It realizes activity analysis based on the individual's speed changes. After it is determined that the individual's movement status is stable, the wind speed of the indoor unit is delayed and quantitatively adjusted. According to the user's own movement, the air volume at the fan speed can be obtained in a positive correlation. Prevent wind speed jumps, improve wind speed control accuracy and intelligence, and optimize user experience.

Based on any of the above embodiments, determining the target rotation speed based on the rotation speed values corresponding to each first target wind speed gear includes: performing a weighted average based on the rotation speed values corresponding to each first target wind speed gear to obtain the target rotation speed.

Specifically, in step 103, when the wind speed control device of the indoor unit determines that there are multiple individuals in the room based on the number of groups of individual movement rates, the first target sub-interval where the individual movement rate of each individual is located is used to obtain the first target sub-interval of the individual movement rate of each individual. Multiple first target wind speed gears corresponding to one target sub-interval. A weighted average of the rotational speed values of multiple first target wind speed gears is used to calculate the target rotational speed, so that the indoor The indoor unit adjusts the fan speed to the target speed so that when supplying air to a group, individuals with greater activity levels will not feel that the air volume is too small, nor will individuals with low activity levels feel that the air volume is too much.

The embodiment of the present application continuously monitors the movement status of individuals in real time based on the radar module, obtains the individual movement rates of multiple individuals, determines the corresponding different wind speed gears through the sub-intervals where the individual movement rates of different individuals are located, and The average value of the rotational speed values corresponding to different wind speed gears is used as the target rotational speed for the indoor unit to adjust the fan rotational speed. It realizes activity volume analysis based on individual speed changes, and adaptively adjusts the wind speed of the indoor unit. It can obtain a more universal air volume based on the movement conditions of multiple users, improving wind speed control accuracy and intelligence. degree to optimize user experience.

Based on any of the above embodiments, after determining the individual movement rate of each individual in the room, the method further includes: marking the individual as the first target individual when it is determined that the individual movement rate of at least one individual is in the first interval. Finally, obtain the individual movement rates of all first target individuals.

The first interval is the rate interval corresponding to when the first target individual is displaced.

It should be noted that the first target individual refers to an individual whose movement rate characteristics are consistent with the elderly.

The first interval refers to the rate interval corresponding to the displacement of elderly individuals determined based on a large amount of prior data. For example, the first interval may be [0,1.32).

Specifically, after step 101, the wind speed control device of the indoor unit performs threshold judgment on the individual movement rates of all individuals.

If it is determined that the individual movement rate of at least one individual among many individuals is in the first interval, it is determined that there is at least one elderly person in the current room. Based on the principle of caring for vulnerable groups, all individuals in the first interval will be regarded as the first target. Individual to obtain the individual movement rates of all elderly people in the room.

If it is determined that there is no individual among many individuals whose movement rate is in the first interval, it is determined that there are no elderly people in the room currently, and there is no need to take care of vulnerable groups. The wind speed is adjusted with reference to the movement rates of other types of individuals.

According to the second target sub-interval corresponding to the individual movement rate of each first target individual, the second target wind speed gear corresponding to each second target sub-interval is obtained.

Among them, the second target sub-interval is obtained by dividing the first interval.

It should be noted that the wind speed control device of the indoor unit pre-sets N ₂ points in the first interval for division, and obtains N ₂ +1 sub-intervals.

Among them, N ₂ is a positive integer greater than or equal to 1. Each sub-interval is correspondingly set with a different second target wind speed gear. Furthermore, the second target wind speed gear increases as the upper limit value of its corresponding sub-interval is closer to the upper limit value of the first interval.

Specifically, in step 102, the wind speed control device of the indoor unit takes the sub-interval where the individual movement rate of each first target individual is located in the first interval as the second target sub-interval, and obtains the sub-interval corresponding to the sub-interval. Second target wind speed gear.

The embodiments of this application do not specifically limit the division of sub-intervals and the setting of corresponding wind speed gears. Illustratively, taking N ₂ equal to 2 as an example, the first interval (in meters per second) can be divided into three sub-intervals, namely [0,0.5), [0.5,1) and [1,1.32), in:

If the individual movement rate of a certain individual is [0,0.5), that is, the first target individual (i.e. the elderly) will be in a static state due to factors such as sleep or being unable to move on his own. Since the amount of activity in this state approaches is less than 0, then the corresponding wind speed gear needs to be set to the silent gear with the lowest wind speed, and the fan speed value corresponding to the silent gear can be 500 revolutions per minute (r/min).

If the individual movement rate of a certain individual is [0.5,1), that is, the first target individual (i.e., the elderly) is in a slow moving state. Since the amount of activity in this state is particularly small, the corresponding wind speed gear needs to be set. It is a low-speed gear with lower wind speed, and the fan speed value corresponding to the low-speed gear can be 660r/min.

If the individual movement rate of an individual is [1,1.32), that is, the first target individual (i.e. the elderly) is in a normal walking state, and since the elderly are a vulnerable group and are not suitable for excessive blowing, the first target individual needs to be The highest wind speed gear corresponding to the target individual is set to the medium speed gear with relatively normal wind speed, and the fan speed value corresponding to the medium speed gear can be 740r/min.

The minimum rotation speed value is selected from all rotation speed values corresponding to the second target wind speed gear and used as the target rotation speed to control the indoor unit to adjust the fan rotation speed to the target rotation speed.

Specifically, in step 103, if the wind speed control device of the indoor unit determines that there are multiple first target individuals in the room, it will select the second target wind speed gear with the lowest wind power from the second target wind speed gears determined by all the first target individuals. The target wind speed gear is set, and the rotation speed value corresponding to the second target wind speed gear is used as the target rotation speed, and the target rotation speed is encapsulated in the control command and sent to the indoor unit.

If the wind speed control device of the indoor unit determines that there is only one first target individual in the room, it can decide whether to determine the target speed based on the principle of caring for the elderly or based on the average value based on the proportion of the first target individual in the total number of indoor individuals. Target speed.

The embodiment of this application monitors the motion status of different types of individuals in real time based on the radar module, obtains the individual motion rate of the first target individual, determines the corresponding wind speed gear through the sub-interval where the real-time motion rate of the old man is located, and selects the lowest The speed value corresponding to the wind speed gear is used as the target speed for the indoor unit to adjust the fan speed. It can identify the types of users included in the group and the corresponding activity status. When it is determined that there are elderly people in the group, based on the principle of giving priority to vulnerable groups, based on the speed changes of individual elderly people, the wind speed of the indoor unit can be adaptively adjusted to improve The control accuracy and intelligence of wind speed optimize the user experience.

Based on any of the above embodiments, after determining the individual movement rate of each individual in the room, the method further includes: marking the individual as the second target individual when it is determined that the individual movement rates of all individuals are in the second interval. Finally, obtain the individual movement rates of all second target individuals.

The second interval is the rate interval corresponding to when the second target individual is displaced. The upper limit value of the second interval is greater than the upper limit value of the first interval.

It should be noted that the second target individual refers to an individual whose movement rate characteristics are consistent with those of young and middle-aged people.

The second interval refers to the rate interval corresponding to the displacement of young and middle-aged individuals, determined based on a large amount of prior data. For example, the second interval may be [0,1.7).

If it is determined that the individual movement rates of all individuals are in the second interval, it is determined that the current room is full of young and middle-aged people, and all individuals in the second interval are regarded as the second target individuals to obtain the data of all young and middle-aged people in the room. individual movement rate.

If it is determined that there is no individual among many individuals whose movement rate is in the second interval, that is, it is determined that there are no young and middle-aged people in the room at present, then it is necessary to take care of vulnerable groups and adjust the wind speed with reference to the movement rate of the first target individual.

According to the third target sub-interval corresponding to the individual movement rate of each second target individual, the third target wind speed gear corresponding to each third target sub-interval is obtained.

Among them, the third target sub-interval is obtained by dividing the second interval.

It should be noted that the wind speed control device of the indoor unit has N ₂ points set in the first interval in advance. Divide and obtain N ₂ +1 sub-intervals.

Specifically, in step 102, the wind speed control device of the indoor unit uses the sub-interval in which the individual movement rates of all second target individuals are located in the second interval as the third target sub-interval, and obtains the third target sub-interval corresponding to the sub-interval. Three target wind speed levels.

The embodiments of this application do not specifically limit the division of sub-intervals and the setting of corresponding wind speed gears. Illustratively, taking N ₃ equal to 3 as an example, the second interval (in meters per second) can be divided into four sub-intervals, namely [0,0.5), [0.5,1), [1,1.5) and [1.5,1.7), where:

If the individual movement rate of an individual is [0,0.5), that is, the second target individual (i.e. young and middle-aged people) will be in a static state due to factors such as sleep or being unable to move on their own.
