Fig. 1 is a flow chart illustrating a method for controlling an air speed of an indoor unit according to an embodiment of the present invention. As shown in fig. 1, a method for controlling a wind speed of an indoor unit according to an embodiment of the present invention includes: step 101, determining the individual movement rate of each individual in the room based on the behavior information fed back by the radar module.
The main execution unit of the method for controlling the air speed of the indoor unit according to the embodiment of the present invention is an air speed control device of the indoor unit.
The application scenario of the air speed control method of the indoor unit provided by the embodiment of the invention is that after a user activates the air conditioner, the activity of an individual is determined through behavior information fed back by the radar module in real time so as to adjust the rotating speed of a fan of the indoor unit, and the discharged air volume is matched with the activity.
The radar module periodically collects the related behavior information of all individuals in the room at a specified time interval, and sends the behavior information to the wind speed control device of the indoor unit. The working period of the radar module is not particularly limited in the embodiments of the present invention.
Optionally, the radar module may perform the acquisition operation in a default duty cycle.
Optionally, the user may send a period change instruction, so that the radar module receives and responds to the instruction, and changes the working period to the period indicated by the instruction to perform the collection operation.
Before step 101, the user needs to send an activation command through the transmission medium to activate the operation mode of the air conditioner, so that the indoor unit of the air conditioner operates at the default wind speed of the mode, and the outdoor unit operates at the default frequency of the mode.
Optionally, the user may transmit the activation instruction through the control device in a wireless communication manner between the control device and the air conditioning system, so that the air conditioning system initializes the operating mode.
Optionally, the user may send an activation instruction in a voice interaction manner, and the air conditioning system receives the activation instruction and initializes the working mode after performing voice recognition.
Specifically, in step 101, after the air conditioner starts the working mode, the wind speed control device of the indoor unit controls and receives the behavior information acquired by the radar module in real time for each individual in the room, and converts the individual movement rate of the individual by using the real-time behavior information of each individual.
The embodiment of the invention does not specifically limit the types and the number of the radar sensing devices in the radar module.
Illustratively, the radar module may include a laser radar, an infrared sensor, and the like.
Optionally, the horizontal detection range of the millimeter wave radar can reach +/-75 degrees, the vertical detection range can reach +/-40 degrees, the farthest detection range can reach 8 meters, the distance output precision can reach 0.1 meter, the angle output precision can reach 1 degree, the privacy problem is not involved, the influence of light rays is avoided, and the response speed is high.
Therefore, the air speed control device of the indoor unit takes the heart rate information acquired by the millimeter wave radar in real time as the current heart rate of the individual user.
Exemplarily, the radar module can comprise multiple sensing elements such as a millimeter wave radar, a laser radar and an infrared sensor, and the wind speed control device of the indoor unit integrates behavior information collected by the sensing elements so as to comprehensively depict the current individual movement rate.
For example, the millimeter wave radar can be used for collecting heart rate information of an individual, and the movement rate corresponding to the current heart rate information can be obtained according to a mapping relation between the heart rate information and the movement rate, which is fit by a large amount of prior data.
And 102, acquiring a first target wind speed gear corresponding to each first target subinterval according to the first target subinterval corresponding to each individual movement rate.
The target subinterval is obtained by interval division of a rate interval corresponding to the displacement of the individual.
In addition, the air speed control device of the indoor unit sets N in advance in the speed range corresponding to the individual displacement 1 Dividing points to obtain N 1 +1 subintervals.
Wherein, N 1 Is a positive integer greater than or equal to 1. And each subinterval is correspondingly provided with a different first target wind speed gear. And, the first target wind speed step increases as the degree of closeness of the upper limit value of its corresponding sub-section to the maximum movement rate increases.
Specifically, in step 102, the wind speed control device of the indoor unit takes a sub-interval in which the individual movement rate of each individual is located as a first target sub-interval, and acquires a first target wind speed gear corresponding to the sub-interval.
The division of the subintervals and the setting of the corresponding wind speed gear in the embodiment of the invention are not particularly limited. Exemplarily, in 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 subintervals, 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 is in a static state under the influence of factors such as sleep or being unable to move by itself, since the activity amount in the state approaches to 0, the corresponding wind speed gear needs to be set to the mute gear with the lowest wind speed, and the fan speed value corresponding to the mute gear may be 500 revolutions per minute (r/min).
If the individual movement speed of an individual is in [0.5,1 ], that is, the individual is in a slow moving state, because the activity amount in the state is very small, the corresponding wind speed gear needs to be set to a low gear with a low wind speed, and the rotating speed value of the fan corresponding to the low 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 movement state, the corresponding wind speed gear needs to be set to a medium gear with a normal wind speed, and the fan rotation speed value corresponding to the medium gear may be 740r/min.
If the individual movement rate of an individual is [1.5,2 ], that is, the individual is in a fast walking movement state, because the activity amount in the state is large, the corresponding wind speed gear needs to be set to a high gear with a high wind speed, and the fan speed value corresponding to the high gear may be 850r/min.
If the individual movement rate of an individual is [2, + ∞ ]), that is, the individual is in the running movement state, since the activity amount in the 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 powerful gear can be 960r/min.
It can be understood that N in the rate interval corresponding to the displacement of the individual 1 The points may also be arranged at unequal intervals to divide a plurality of unequal rate sub-intervals.
And 103, determining a target rotating speed based on the rotating speed value corresponding to each first target wind speed gear so as to control the indoor unit to adjust the rotating speed of the fan to the target rotating speed.
Specifically, in step 103, the wind speed control device of the indoor unit calculates a target rotation speed according to the number of indoor individuals and a rotation speed value corresponding to the first target wind speed gear acquired by each individual, packages the target rotation speed in a control command, and sends the control command to the indoor unit.
The indoor unit receives and responds to the control instruction, and the fan rotating speed of the fan inside the indoor unit is adjusted to be the target rotating speed.
The embodiment of the present invention does not specifically limit the calculation manner of the target rotation speed.
Optionally, when the wind speed control device of the indoor unit determines that an individual exists in the room according to the group number of the individual movement rates, a sub-interval where the individual movement rate of the individual is located is used to obtain a wind speed gear corresponding to the sub-interval, and the rotation speed value of the gear is used as a target rotation speed, so that the indoor unit adjusts the rotation speed of the fan to the target rotation speed to perform targeted air supply on the individual.
Optionally, when the wind speed control device of the indoor unit determines that a plurality of individuals exist in the room according to the group number of the individual movement rates, the wind speed control device acquires a plurality of wind speed gears corresponding to different subintervals by using the subintervals where the individual movement rates of each individual are located. And selecting the weakest wind speed gear for air supply on the basis of taking the weak group as a principle, and taking the rotating speed value of the gear as a target rotating speed to enable the indoor unit to adjust the rotating speed of the fan to the target rotating speed so as to perform universal air supply on the group.
The embodiment of the invention monitors the motion state of an individual in real time based on a radar module to obtain the individual motion speed, determines a corresponding wind speed gear according to a subinterval where the individual motion speed is positioned, and converts a target rotating speed by using a rotating speed value corresponding to the wind speed gear so as to adjust the rotating speed of a fan by an indoor unit. The activity analysis is carried out according to the individual speed change condition, the air speed of the indoor unit is adaptively adjusted, the air quantity under the positive correlation fan rotating speed can be obtained according to the motion condition of a user, the control precision and the intelligent degree of the air speed are improved, and the user experience is optimized.
On the basis of any of the above embodiments, after obtaining the first target wind speed gear corresponding to each first target subinterval according to the first target subinterval corresponding to each individual movement rate, the method further includes: and determining a new individual movement rate of each individual based on the re-acquired behavior information within a preset time length.
It should be noted that the preset duration refers to a duration for continuing monitoring the motion condition after preliminarily determining the first target sub-interval in which the individual motion rate is located. And the preset time is used for delaying to control the indoor unit to adjust the rotating speed of the fan after preliminarily determining the target rotating speed.
The value of the preset time period is not specifically limited, and the preset time period may be 2 minutes as an example.
Specifically, after step 102, the wind speed control device of the indoor unit receives the behavior information that the radar module continuously monitors each individual within the preset time period, and calculates a new individual movement rate of the corresponding individual at the next time by using the behavior information that each individual reacquires.
And under the condition that any new individual movement rate is still in the first target subinterval corresponding to the individual movement rate, acquiring a first target wind speed gear corresponding to each first target subinterval.
Specifically, the wind speed control device of the indoor unit compares the new individual movement rate of each individual with the original interval range determined by the individual in step 102 (i.e., the first target subinterval corresponding to the individual).
And if the new individual movement rate is still in the original interval range of the individual, namely the individual movement rate is always in a set first target subinterval within a preset time length, and the individual movement state is determined to be relatively stable, determining a first target wind speed gear matched with the individual movement amount according to the subinterval.
If the new individual movement rate is not in the original interval range of the individual, namely the individual movement rate is changed in the preset time length, and the individual movement state is determined to be relatively unstable, the individual movement amount cannot be determined, the individual movement condition needs to be continuously monitored until the individual movement rates in the preset time length are in the same sub-interval, and the wind speed gear matched with the individual movement amount can be determined according to the sub-interval.
And determining a target rotating speed based on the rotating speed value corresponding to each first target wind speed gear so as to control the indoor unit to adjust the rotating speed of the fan to the target rotating speed.
Specifically, the air speed control device of the indoor unit executes the control logic for all indoor units, obtains a first target air speed gear corresponding to each unit in a stable moving state, calculates a target rotating speed according to a rotating speed value corresponding to each first target air speed gear, packages the target rotating speed in a control instruction, and sends the control instruction to the indoor unit.
The indoor unit receives and responds to the control instruction, and the rotating speed of the fan in the indoor unit is adjusted to be the target rotating speed.
The method and the device for adjusting the fan speed of the air conditioner in the embodiment of the invention continuously monitor the individual motion state in real time based on the radar module within the preset time length to obtain the individual motion speed, determine the air speed gear in the stable moving state by the fact that a plurality of groups of individual motion speeds are in the same subinterval, and convert the target rotating speed by using the rotating speed value corresponding to the air speed gear so as to adjust the rotating speed of the fan by the indoor unit. The air quantity under the positive correlation fan rotating speed can be obtained according to the motion condition of a user, the air speed jumping is prevented, the control precision and the intelligent degree of the air speed are improved, and the user experience is optimized.
On the basis of any one of the above embodiments, determining the target rotation speed based on the rotation speed value corresponding to each first target wind speed gear includes: and carrying out weighted average on the rotating speed values corresponding to the first target wind speed gears to obtain the target rotating speed.
Specifically, in step 103, when the wind speed control device of the indoor unit determines that a plurality of individuals exist in the room according to the group number of the individual movement rates, a plurality of first target wind speed gears corresponding to different first target subintervals are acquired by using the first target subintervals where the individual movement rates of each individual are located. And carrying out weighted average on the rotating speed values of various first target wind speed gears, calculating a target rotating speed, and adjusting the rotating speed of the fan to the target rotating speed by the indoor unit, so that when a group is supplied with wind, individuals with large activity can not feel too little wind quantity, and individuals with small activity can not feel too much wind quantity.
The embodiment of the invention continuously monitors the motion state of the individuals in real time based on the radar module, obtains the individual motion rates of a plurality of individuals, determines corresponding different wind speed gears according to subintervals where the individual motion rates of different individuals are positioned, and takes the average value of the rotating speed values corresponding to the different wind speed gears as the target rotating speed so as to adjust the rotating speed of the fan by the indoor unit.

Specifically, after step 101, the wind speed control device of the indoor unit performs threshold determination on the individual movement rates of all the individuals.
If the situation that the individual movement rate of at least one individual in the plurality of individuals is in the first interval is determined, the current indoor presence of at least one old man is determined, all the individuals in the first interval are taken as first target individuals on the basis of the principle of caring the vulnerable group, and the individual movement rates of all the old men in the room are obtained.
If the situation that the individual movement rate of the individual is not in the first interval in a plurality of individuals is determined, namely the current indoor old people is determined to be absent, the vulnerable group does not need to be taken care of, and the wind speed is adjusted by referring to the movement rates of other types of individuals.

If the individual movement rate of a certain individual is [0.5,1 ], that is, the first target individual (i.e., the old person) is in a slow moving state, because the activity amount in the state is very small, the corresponding wind speed gear needs to be set to a low gear with a low wind speed, and the fan rotation speed value corresponding to the low gear may be 660r/min.
If the individual movement rate of one individual is [1,1.32 ], that is, the first target individual (i.e., the old man) is in a normal walking movement state, and the old man group is a weak group and is not suitable for excessive blowing, the highest wind speed gear corresponding to the first target individual needs to be set as a middle gear with a normal wind speed, and the fan rotating speed value corresponding to the middle gear can be 740r/min.

If the air speed control device of the indoor unit determines that only one first target individual exists indoors, the target rotating speed can be determined on the basis of the principle of taking care of the elderly population or on the basis of the average value according to the proportion of the first target individual in the total number of the indoor individuals.
The indoor unit receives and responds to the control instruction, and the rotating speed of the fan in the indoor unit is adjusted to be the target rotating speed.
The method and the device have the advantages that the motion states of different types of individuals are monitored in real time based on Lei Damo groups, the individual motion speed of a first target individual is obtained, a corresponding wind speed gear is determined according to a subinterval where the real-time motion speed of the old is located, and a rotating speed value corresponding to the lowest wind speed gear is selected as a target rotating speed so that an indoor unit can adjust the rotating speed of a fan. The method can identify the user types and the corresponding activity states contained in the group, when the old people in the group are determined, the wind speed of the indoor unit is adaptively adjusted according to the speed change condition of the individual old people by taking the preference of the weak group as the principle, so that the control precision and the intelligent degree of the wind speed are improved, and the user experience is optimized.

And the second interval is a rate interval corresponding to the displacement of the second target individual. The upper limit value of the second interval is greater than that of the first interval.
The second target individual is an individual having a characteristic of a moving rate suitable for young and middle-aged people.
The second interval is a rate interval corresponding to the displacement of the middle-aged and young people determined according to a large amount of prior data. Illustratively, the second interval may be [0,1.7).
Specifically, after step 101, the wind speed control device of the indoor unit performs threshold determination on the individual movement rates of all the individuals.

If the situation that the individual movement rate of the plurality of individuals is not in the second interval is determined, namely, no middle-aged or young people are determined to be in the current room, the vulnerable group needs to be taken care of, and the wind speed is adjusted by referring to the movement rate of the first target individual.
And acquiring a third target wind speed gear corresponding to each third target subinterval according to the third target subinterval corresponding to the individual movement rate of each second target individual.
And the third target subinterval is obtained by performing interval division on the second interval.
The air speed control device of the indoor unit is previously set to the first air speed control deviceWithin a section, N is set 2 Dividing points to obtain N 2 +1 subintervals.

And, the second target wind speed step increases as the degree of closeness of the upper limit value of its corresponding sub-section to the upper limit value of the first section increases.
