Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0045] It should be understood that the terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present invention, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0046] The terms “include” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0047] Figure 1 FIG. 1 is a flow chart of the wind speed control method of the indoor unit provided by the present invention. Figure 1 As shown, the wind speed control method of the indoor unit provided by the 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.

[0048] It should be noted that the execution body of the wind speed control method of the indoor unit provided by the embodiment of the present invention is the wind speed control device of the indoor unit.

[0049] The application scenario of the wind speed control method of the indoor unit provided by the embodiment of the present invention is that when 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 so that the exhaust air volume is adapted to the activity level.

[0050] The radar module periodically collects relevant 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 embodiment of the present invention does not specifically limit the working cycle of the radar module.

[0051] Optionally, the radar module can perform data collection operations in a default working cycle.

[0052] Optionally, the user can issue a cycle change instruction so that the radar module receives and responds to the instruction and changes the working cycle to the cycle indicated by the instruction to perform acquisition operations.

[0053] It should be noted that before step 101, the user needs to send an activation instruction 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 the mode, and the outdoor unit runs at the default frequency of the mode.

[0054] Optionally, the user may transmit an activation instruction through the control device by wireless communication between the control device and the air-conditioning system, so that the air-conditioning system initializes the working mode.

[0055] Optionally, the user may issue an activation instruction through voice interaction, and the air-conditioning system receives the activation instruction, performs voice recognition, and initializes the working mode.

[0056] Specifically, in step 101, after the air conditioner starts the working mode, the wind speed control device of the indoor unit controls the behavior information collected by the receiving radar module on each individual in the room in real time, and uses the real-time behavior information of each individual to convert the individual movement rate of the individual.

[0057] The embodiment of the present invention does not specifically limit the type and quantity of radar sensing devices in the radar module.

[0058] For example, the radar module may include a laser radar, an infrared sensor, etc.

[0059] Optionally, since the horizontal detection range of the millimeter-wave radar can reach ±75°, the vertical detection range can reach ±40°, the maximum detection distance can reach 8 meters, the distance output accuracy can reach 0.1 meters, 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 fast.

[0060] 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.

[0061] For example, the radar module may include multiple sensor elements such as millimeter wave radar, lidar, infrared sensor, etc. The wind speed control device of the indoor unit integrates the behavioral information collected by each sensor element to comprehensively depict the current individual movement rate.

[0062] For example, millimeter-wave radar can be used to collect an individual's 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.

[0063] Step 102: Obtain a first target wind speed level corresponding to each first target sub-interval according to the first target sub-interval corresponding to each individual movement rate.

[0064] The target sub-interval is obtained by dividing the rate interval corresponding to the displacement of the individual.

[0065] It should be noted that the wind speed control device of the indoor unit pre-sets N1 points in the speed interval corresponding to the displacement of the individual to divide the interval into N1+1 sub-intervals.

[0066] Wherein, N1 is a positive integer greater than or equal to 1. Each sub-interval corresponds to a different first target wind speed level. Moreover, the first target wind speed level increases as the upper limit value of the corresponding sub-interval approaches the maximum movement rate.

[0067] Specifically, in step 102, the wind speed control device of the indoor unit takes the sub-interval in which the individual movement rate of each individual is located as the first target sub-interval, and obtains the first target wind speed level corresponding to the sub-interval.

[0068] The embodiment of the present invention does not specifically limit the division of sub-intervals and the setting of corresponding wind speed gears. For example, taking N1 equal to 4 as an example, the speed interval corresponding to the displacement of the human body (in meters per second) can be divided into five sub-intervals, namely [0, 0.5), [0.5, 1), [1, 1.5), [1.5, 2), and [2, +∞), where:

[0069] If the individual movement rate of an individual is in [0,0.5), that is, the individual will be in a static state due to factors such as sleep or inability to move on their own. Since the activity level in this state is close to 0, 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).

[0070] If the individual movement rate of an individual is in [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 lower wind speed, and the fan speed value corresponding to the low speed gear can be 660r / min.

[0071] If the individual movement rate of an individual is in [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 fan speed value corresponding to the medium speed gear can be 740r / min.

[0072] If the individual movement rate of an individual is in [1.5,2), that is, the individual is in a faster walking state, due to the large amount of activity in this state, the corresponding wind speed gear needs to be set to a high speed gear with a higher wind speed, and the fan speed value corresponding to the high speed gear can be 850r / min.

[0073] If the individual movement rate of an individual is in [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 strong gear with the highest wind speed, and the fan speed value corresponding to the strong gear can be 960r / min.

[0074] It is understandable that the N1 points within the velocity interval corresponding to the displacement of the individual may also be arranged at unequal intervals to divide the intervals into a plurality of unequal velocity sub-intervals.

[0075] Step 103: Determine a target speed based on the speed values ​​corresponding to the first target wind speed levels, so as to control the indoor unit to adjust the fan speed to the target speed.

[0076] 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 speed value corresponding to the first target wind speed level obtained by each individual, and encapsulates the target speed in a control instruction and sends it to the indoor unit.

[0077] The indoor unit receives and responds to the control command, adjusting the fan speed of its internal fan to the target speed.

[0078] The embodiment of the present invention does not specifically limit the method for calculating the target rotational speed.

[0079] Optionally, when the wind speed control device of the indoor unit determines that there is an individual in the room based on the number of groups of individual movement rates, it uses the sub-interval of the individual movement rate of the individual to obtain the wind speed gear corresponding to the sub-interval, and uses the speed value of the gear as the target speed, so that the indoor unit adjusts the fan speed to the target speed to provide targeted air supply to the individual.

[0080] Optionally, when the indoor unit's wind speed control device determines the presence of multiple individuals in the room based on the number of individual motion rate groups, it utilizes the subranges within which each individual's individual motion rate falls to obtain multiple wind speed levels corresponding to different subranges. To provide for vulnerable groups, the weakest wind speed level is selected for air delivery, and the speed value of this speed level is used as the target speed. The indoor unit adjusts the fan speed to the target speed, thereby providing universal air delivery to the group.

[0081] This embodiment of the present invention uses a radar module to monitor an individual's motion state in real time, obtaining their motion rate. The system then determines the corresponding wind speed level based on the sub-interval of their motion rate. The speed value corresponding to that wind speed level is then converted into a target speed for the indoor unit to adjust the fan speed. This system analyzes activity levels based on individual velocity changes and adjusts the indoor unit's wind speed accordingly. This system can determine the air volume at a positively correlated fan speed based on the user's motion, improving wind speed control accuracy and intelligence, and optimizing the user experience.

[0082] On the basis of any of the above embodiments, after obtaining the first target wind speed level corresponding to each first target sub-interval according to the first target sub-interval corresponding to each individual's movement rate, it also includes: determining the new individual movement rate of each individual based on the re-acquired behavior information within a preset time period.

[0083] It should be noted that the preset duration refers to the duration of continued motion monitoring after the individual's motion rate is initially determined to be in the first target sub-interval. The preset duration is used to delay the indoor unit's fan speed adjustment after the target speed is initially determined.

[0084] The embodiment of the present invention does not specifically limit the value of the preset duration. Exemplarily, the preset duration may be 2 minutes.

[0085] Specifically, after step 102, the wind speed control device of the indoor unit receives the behavior information of each individual continuously monitored by the radar module within a preset time period, and uses the behavior information regained by each individual to calculate the new individual movement rate of the corresponding individual at the next moment.

[0086] When it is determined that any new individual movement rate is still within the first target sub-interval corresponding to the individual movement rate, the first target wind speed level corresponding to each first target sub-interval is obtained.

[0087] 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 for the individual in step 102 (ie, the first target sub-interval corresponding to the individual).

[0088] If the new individual movement rate is still within the original range of the individual, that is, the individual's movement rate has been in the established first target sub-range within the preset time, and the individual's movement state is determined to be relatively stable, the first target wind speed level that matches the individual's activity level is determined based on the sub-range.

[0089] If the new individual movement rate is not within the original range of the individual, that is, the individual's movement rate changes within the preset time, and the individual's movement state is determined to be relatively unstable, the individual's activity level cannot be determined. It is necessary to continue monitoring the individual's movement until the individual movement rate within the preset time is in the same sub-range, and then the wind speed level that matches its activity level can be determined based on the sub-range.

[0090] Based on the rotation speed values ​​corresponding to the first target wind speed gears, a target rotation speed is determined to control the indoor unit to adjust the fan rotation speed to the target rotation speed.

[0091] Specifically, the wind speed control device of the indoor unit executes the above control logic for all individuals in the room. After obtaining the first target wind speed level corresponding to each individual in a stable moving state, the target speed is calculated based on the speed value corresponding to each first target wind speed level, and the target speed is encapsulated in a control instruction and sent to the indoor unit.

[0092] The indoor unit receives and responds to the control command, adjusting the fan speed of its internal fan to the target speed.

[0093] The embodiment of the present invention uses a radar module to continuously monitor an individual's motion state in real time over a preset duration, obtaining the individual's motion rate. By locating multiple groups of individual motion rates within the same sub-interval, the system determines the wind speed level under stable motion conditions. The system then uses the speed value corresponding to that wind speed level to calculate the target speed for the indoor unit to adjust the fan speed. This system analyzes activity levels based on individual velocity changes, delaying and quantitatively adjusting the indoor unit's wind speed after determining that the individual's motion state is stable. This system can determine the air volume at a positively correlated fan speed based on the user's motion conditions, preventing wind speed jumps, improving wind speed control accuracy and intelligence, and optimizing the user experience.

[0094] Based on any of the above embodiments, determining the target speed based on the speed values ​​corresponding to each first target wind speed gear includes: performing weighted averaging on the speed values ​​corresponding to each first target wind speed gear to obtain the target speed.

[0095] Specifically, in step 103, the indoor unit's wind speed control device determines, based on the number of groups of individual movement rates, that there are multiple individuals in the room. The device then uses the first target sub-interval within which each individual's individual movement rate falls to obtain multiple first target wind speed levels corresponding to different first target sub-intervals. The speed values ​​of the multiple first target wind speed levels are weighted averaged to calculate a target speed, causing the indoor unit to adjust the fan speed to the target speed. This ensures that when air is supplied to the group, individuals with high activity levels experience neither excessive airflow nor excessive airflow for individuals with low activity levels.

[0096] The embodiment of the present invention uses a radar module to continuously monitor the movement status of individuals in real time, obtain the individual movement rates of multiple individuals, determine the corresponding different wind speed levels based on the sub-intervals of the individual movement rates, and use the average of the rotational speed values ​​corresponding to the different wind speed levels as the target speed for the indoor unit to adjust the fan speed. This enables activity analysis based on individual speed changes and adaptive adjustment of the indoor unit's wind speed. This allows for a highly universal air volume based on the movement patterns of multiple users, improving the precision and intelligence of wind speed control, and optimizing the user experience.

[0097] Based on any of the above embodiments, after determining the individual motion rate of each individual in the room, it also includes: when determining that the individual motion rate of at least one individual is in the first range, marking the individual as a first target individual, and obtaining the individual motion rates of all first target individuals.

[0098] The first interval is the velocity interval corresponding to the displacement of the first target individual.

[0099] It should be noted that the first target individual refers to an individual whose movement speed characteristics are consistent with those of an elderly person.

[0100] The first interval refers to a velocity interval corresponding to the displacement of an elderly individual, determined based on a large amount of prior data. For example, the first interval may be [0, 1.32).

[0101] Specifically, after step 101, the wind speed control device of the indoor unit performs threshold judgment on the individual motion rates of all individuals.

[0102] 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 room. Based on the principle of caring for vulnerable groups, all individuals in the first interval are taken as the first target individuals to obtain the individual movement rates of all elderly people in the room.

[0103] If it is determined that there is no individual whose individual movement rate is in the first interval among the many individuals, that is, it is determined that there are no elderly people in the room, there is no need to take care of the vulnerable groups, and the wind speed is adjusted with reference to the movement rates of other types of individuals.

[0104] According to the second target sub-interval corresponding to the individual movement speed of each first target individual, the second target wind speed level corresponding to each second target sub-interval is obtained.

[0105] The second target sub-interval is obtained by dividing the first interval.

[0106] It should be noted that the wind speed control device of the indoor unit pre-sets N2 points in the first interval for division to obtain N2+1 sub-intervals.

[0107] Wherein, N2 is a positive integer greater than or equal to 1. Each sub-interval corresponds to a different second target wind speed level. Moreover, the second target wind speed level increases as the upper limit of the corresponding sub-interval approaches the upper limit of the first interval.

[0108] Specifically, in step 102, the wind speed control device of the indoor unit takes the sub-interval in which the individual movement rate of each first target individual in the first interval is located as the second target sub-interval, and obtains the second target wind speed level corresponding to the sub-interval.

[0109] The embodiment of the present invention does not specifically limit the division of sub-intervals and the setting of corresponding wind speed levels. For example, taking N2 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), where:

[0110] If the individual movement rate of an individual is in [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 inability to move on their own. Since the activity level in this state is close to 0, 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).

[0111] If the individual movement rate of a certain individual is in [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 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.

[0112] If the individual movement rate of a certain individual is in [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 wind blowing, the maximum wind speed gear corresponding to the first target individual needs to be set to a medium speed gear with a relatively normal wind speed, and the fan speed value corresponding to the medium speed gear can be 740r / min.

[0113] The minimum speed value is selected from the speed values ​​corresponding to all the second target wind speed gears as the target speed, so as to control the indoor unit to adjust the fan speed to the target speed.

[0114] Specifically, in step 103, if the wind speed control device of the indoor unit determines that there are multiple first target individuals indoors, it will screen out the second target wind speed level with the lowest wind force from the second target wind speed levels determined by all the first target individuals, and use the speed value corresponding to the second target wind speed level as the target speed, and encapsulate the target speed in a control instruction and send it to the indoor unit.

[0115] 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 group or by taking the average value based on the proportion of the first target individual to the total number of individuals in the room.

[0116] The indoor unit receives and responds to the control command, adjusting the fan speed of its internal fan to the target speed.

[0117] The embodiment of the present invention uses a radar module to monitor the motion status of different types of individuals in real time, obtains the individual motion rate of a first target individual, determines the corresponding wind speed level based on the sub-interval of the elderly person's real-time motion rate, and selects the speed value corresponding to the lowest wind speed level as the target speed for the indoor unit to adjust the fan speed. It can identify the user types included in a group and their corresponding activity levels. When it is determined that there are elderly people in the group, the principle of prioritizing vulnerable groups is adopted. Based on the individual elderly person's speed changes, the indoor unit's wind speed is adaptively adjusted, improving the control accuracy and intelligence of wind speed and optimizing the user experience.

[0118] Based on any of the above embodiments, after determining the individual motion rate of each individual in the room, it also includes: when it is determined that the individual motion rates of all individuals are in the second interval, the individual is marked as a second target individual, and the individual motion rates of all second target individuals are obtained.

[0119] The second interval is a velocity interval corresponding to the displacement of the second target individual, and the upper limit of the second interval is greater than the upper limit of the first interval.

[0120] It should be noted that the second target individual refers to an individual whose movement speed characteristics are consistent with those of young and middle-aged people.

[0121] The second interval refers to the velocity 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).

[0122] Specifically, after step 101, the wind speed control device of the indoor unit performs threshold judgment on the individual motion rates of all individuals.

[0123] If it is determined that the individual motion rates of all individuals are in the second interval, it is determined that all the people in the room are young and middle-aged people, and all individuals in the second interval are taken as second target individuals to obtain the individual motion rates of all young and middle-aged people in the room.

[0124] If it is determined that there is no individual whose individual movement rate is in the second range among the many individuals, that is, it is determined that there are no young or middle-aged people in the room, then it is necessary to take care of the vulnerable groups and adjust the wind speed with reference to the movement rate of the first target individual.

[0125] The third target wind speed level corresponding to each third target sub-interval is obtained according to the third target sub-interval corresponding to the individual movement rate of each second target individual.

[0126] The third target sub-interval is obtained by dividing the second interval.

[0127] It should be noted that the wind speed control device of the indoor unit pre-sets N2 points in the first interval for division to obtain N2+1 sub-intervals.

[0128] Wherein, N2 is a positive integer greater than or equal to 1. Each sub-interval corresponds to a different second target wind speed level. Moreover, the second target wind speed level increases as the upper limit of the corresponding sub-interval approaches the upper limit of the first interval.

[0129] Specifically, in step 102, the wind speed control device of the indoor unit takes the sub-interval where 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 wind speed level corresponding to the sub-interval.

[0130] The embodiment of the present invention does not specifically limit the division of sub-intervals and the setting of corresponding wind speed levels. For example, taking N3 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:

[0131] If the individual movement rate of an individual is in [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 inability to move on their own. Since the activity level in this state approaches 0, 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).

[0132] If the individual movement rate of a certain individual is in [0.5,1), that is, the second target individual (i.e., young and middle-aged people) 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.

[0133] If the individual movement rate of an individual is in [1,1.5), that is, the second target individual (i.e., young and middle-aged people) is in a normal walking state. Since the amount of activity in this state is at a normal level, the wind speed gear needs to be set to a medium speed gear with a relatively normal wind speed, and the fan speed value corresponding to the medium speed gear can be 740r / min.

[0134] If the individual movement rate of an individual is in [1.5,1.7), that is, the individual is in a faster walking state, due to the large amount of activity in this state, the corresponding wind speed gear needs to be set to a high-speed gear with a higher wind speed, and the fan speed value corresponding to the high-speed gear can be 850r / min.

[0135] Based on the rotation speed values ​​corresponding to all third target wind speed levels, a target rotation speed is determined to control the indoor unit to adjust the fan rotation speed to the target rotation speed.

[0136] Specifically, in step 103, if the wind speed control device of the indoor unit determines that all individuals in the room are second target individuals, it calculates the target speed based on the speed values ​​corresponding to the third target wind speed level determined by all second target individuals, encapsulates the target speed in a control instruction, and sends it to the indoor unit.

[0137] If the wind speed control device of the indoor unit determines that not all individuals in the room are second target individuals, it can decide whether to determine the target speed based on the principle of caring for the elderly group or by taking the average value based on the proportion of second target individuals in the total number of individuals in the room.

[0138] The indoor unit receives and responds to the control command, adjusting the fan speed of its internal fan to the target speed.

[0139] This embodiment of the present invention uses a radar module to monitor the motion status of different types of individuals in real time, obtain the individual motion rate of a second target individual, determine the corresponding wind speed level based on the sub-interval of the real-time motion rate of young and middle-aged individuals, and calculate the target speed for the indoor unit to adjust the fan speed. It can identify the user types and corresponding activity levels within a group. If the group is determined to be entirely young and middle-aged, the indoor unit's wind speed can be adaptively adjusted based on the individual speed changes of young and middle-aged individuals, improving the precision and intelligence of wind speed control and optimizing the user experience.

[0140] On the basis of any of the above embodiments, the individual movement rate of each individual in the room is determined based on the behavior information fed back by the radar module, including: extracting the individual displacement data and the acquisition time of the displacement data from the behavior information.

[0141] Specifically, in step 101, the wind speed control device of the indoor unit extracts the displacement data of each individual obtained at different acquisition times from the behavior information fed back by the radar module.

[0142] Based on the displacement data and the time at which the displacement data was collected, an individual movement rate of the individual is determined.

[0143] Specifically, for any individual, the wind speed control device of the indoor unit can use the displacement data collected at any two or more collection times, substitute them into the motion model for calculation, and convert the individual motion rate of the individual.

[0144] This embodiment of the present invention uses the displacement data of different individuals collected by a radar module at different acquisition times to calculate the individual's motion rate at corresponding time intervals. It then determines the speed value of the corresponding wind speed level based on the sub-interval of the individual's real-time motion rate, and converts it into a target speed for the indoor unit to adjust the fan speed. This allows for activity analysis based on the individual's motion rate as it changes over time, and for adaptive adjustment of the indoor unit's wind speed. This allows for the determination of air volume at a positively correlated fan speed based on the user's physical activity, improving the precision and intelligence of wind speed control and optimizing the user experience.
