Figure 1 is a schematic flowchart of an indoor unit control method provided by this application. As shown in Figure 1, the control method of an indoor unit provided by the embodiment of the present application includes: Step 101: Determine a height range based on the first position information and the second position information of the indoor individual.

Wherein, the first position information and the second position information are collected by a radar module.

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

The application scenario of the indoor unit control method provided by the embodiment of the present application is that after the user activates the air conditioner, the head position and foot position of the indoor individual are actually monitored through the radar module to detect the movement of the human body from the head in the vertical direction. The human body coverage area determined by the head and footsteps is regarded as the effective area, and the non-human body coverage area in the vertical direction of the room is regarded as the invalid area, and the indoor unit is controlled to perform slow swing in the effective area and fast swing in the invalid area. .

Among them, the radar module periodically collects the first position information and the second position information of all individuals in the room at specified time intervals, and combines the first position information belonging to the same individual. and the second position information are stored in the same information storage unit and sent to the control device of the indoor unit.

The first position information refers to the head position information of an individual in the room.

The second position information refers to the foot position information of an individual in the room.

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 a period of time after the air conditioner starts working mode, the control device of the indoor unit receives the first position information and the second position information periodically collected by the radar module for each individual in the room, and The first position information and the second position information of the multiple groups of individuals are stored in a set corresponding to the current time to form the height range of the indoor individuals in the current period.

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 control device of the indoor unit uses the movement angle, displacement point and other information collected in real time by the millimeter wave radar as the user's individual location information. It can also collect acceleration, speed and other information to calculate the user's individual location information.

For example, the radar module can include a variety of sensing elements such as millimeter wave radar, lidar, and infrared sensors. The control device of the indoor unit integrates the behavioral information collected by each sensing element to comprehensively characterize the individual. Current location information and behavior information.

For example, millimeter-wave radar can be used to collect individual heart rate information. According to a large amount of prior data, it is proved that in the case of non-emergency diseases, heart rate and human body exercise are often positively correlated. Based on the above correspondence, if the room is within the effective area, If the overall heart rate of an individual user is high, the wind speed can be appropriately increased in the cooling mode to increase the cooling capacity.

Step 102: If it is determined that the similarity between the height range and the preset height range is less than the preset threshold, set a first execution position and a second execution position based on the height range.

Wherein, the first execution position is in the upper area of the air outlet, and the angle formed by the first execution position with respect to the horizontal plane where the radar module is located is greater than 0; the second execution position is in the The lower side area of the air outlet, and the angle formed by the second execution position relative to the horizontal plane where the radar module is located is less than 0.

It should be noted that the preset altitude range refers to a set composed of the first position information and the second position information collected by the radar module in the historical period before the current time.

Specifically, in step 102, the control device of the indoor unit compares the displacement points contained in the current height range of the user individual with the angular displacement points in the preset height range. The higher the coincidence rate of the displacement points in the two sets, then The greater the similarity between the height range and the preset height range.

If the similarity between the height range and the preset height range is less than the preset threshold, it means that the head and foot positions monitored by the radar module will change simultaneously because the indoor individual is close to or away from the air conditioner. The mapping relationship between the height range and the execution angle determines the first execution position and the second execution position respectively corresponding to the two ends of the height range.

If the similarity between the height range and the preset coverage range is greater than or equal to the preset threshold, it means that the indoor individual has not undergone lateral displacement relative to the air conditioner, causing the head and feet monitored by the radar module to If the position does not change at the same time, the first execution position and the second execution position respectively corresponding to both ends of the current range are determined based on the preset height range or height range and the mapping relationship between the height range and the execution angle.

The first execution position corresponds to the first end of the height range and is located in the upper half of the air outlet. The second execution position corresponds to the second end of the height range and is located in the lower half of the air outlet.

The embodiment of the present application does not specifically limit the value ranges of the first execution position and the second execution position.

For example, in the horizontal plane where the radar module is located, the position of the radar module is the origin, and the vertical line perpendicular to the origin is the Z-axis. Taking the direction pointing to the roof as the positive Z-axis direction, The direction toward the ground is the negative Z-axis direction.

The angle between the first execution position above the XY horizontal plane and the horizontal plane is recorded as a positive value, and the value of the angle ranges from 0° to 90°.

The angle between the second execution position below the XY horizontal plane and the horizontal plane is recorded as a negative value, and the value range of the included angle is -90° to 0°.

Step 103: Based on the first execution position and the second execution position, adjust the swing speed of the sway blade assembly in the rated swing wind area.

Specifically, in step 103, the control device of the indoor unit uses the angular area defined by the first execution position and the second execution position obtained in step 102 as the enhanced wind swing area, and divides the rated wind swing area into the first The area of the angular area defined by the execution position and the second execution position serves as the weakened sway wind area. The first execution position and the second execution position are packaged into control instructions and sent to the indoor unit.

The indoor unit receives and responds to the control command, and when controlling the sway blade assembly to swing back and forth in the rated sway area, it lowers the up and down of the assembly in the enhanced sway area based on the analyzed first execution position and second execution position. Swing speed, and increase the up and down swing speed of the component in the weakened swing wind area.

The embodiment of the present application monitors the height range of an individual in real time based on the radar module, and sets the first execution position and the second execution position through height range decision-making to slow down the swing between the first execution position and the second execution position. speed, and accelerates the swing speed in the remaining areas, realizing that when the vertical coverage area of the human body changes due to movement, the swing speed of the horizontal guide plate in the corresponding range is optimally controlled, so that the vertical area corresponding to the human body is slowly swept. , quickly sweep the air in non-human body areas, improve the control accuracy and efficiency of the indoor unit, and optimize the user experience.

Based on any of the above embodiments, based on the first execution position and the second execution position, adjusting the swing speed of the sway blade assembly in the rated swing wind area includes: in the third execution position and the fourth execution position. During the reciprocating swing process between positions, the current position of the swing blade assembly is obtained.

Wherein, the third execution position and the fourth execution position are respectively the starting positions of the rated swing wind area.

It should be noted that the range formed between the third execution position and the fourth execution position is the rated air swing area initially set for the corresponding model of air conditioner, where the third execution position is located The limit swing position of the upper zone, and the fourth execution position is the limit swing position of the lower zone.

Specifically, during the process of controlling the reciprocating swing of the oscillating blade assembly between the third execution position and the fourth execution position, the control device of the indoor unit acquires the current position of the oscillating blade assembly in real time.

If it is determined that the current position of the yaw blade assembly is in the first target area, control the yaw blade assembly to swing in the first target area at a first speed;

If it is determined that the current position of the yaw blade assembly is in the second target area, control the yaw blade assembly to swing in the second target area at a second speed;

If it is determined that the current position of the yaw blade assembly is in the third target area, control the yaw blade assembly to swing in the third target area at the first speed;

Wherein, the first target area, the second target area and the third target area are determined based on the first execution position and the second execution position. The first speed is greater than the second speed.

It should be noted that according to the first execution position and the second execution position, the rated swing wind area is divided into a first target area, a second target area and a third target area that are adjacent up and down.

Among them, the first target area is an invalid area other than the human body, and its starting position is the third execution position and the first execution position.

The second target area is the effective area covered vertically by the human body, and its starting position is the first execution position and the second execution position.

The third target area is an invalid area other than the human body, and its starting position is the second execution position and the fourth execution position.

Specifically, the control device of the indoor unit sets the swing speed of the oscillating blade assembly in the first target area and the third target area to a faster first speed, and sets the swing speed of the oscillating blade assembly in the second target area. The speed is set to a slower second speed, and the reciprocating wind swing process between the third execution position and the fourth execution position can iteratively perform the following steps:

During the process of the third execution position swinging up and down to the fourth execution position, the yaw blade assembly is controlled to move from the third execution position to the first execution position at the first speed, and then switches to the second speed to move from the first execution position to the first execution position. the second execution position, and finally returns to the first speed and moves from the second execution position to the fourth execution position.

During the process of the fourth execution position swinging up and down to the third execution position, the yaw blade assembly is controlled to move from the fourth execution position to the second execution position at the first speed, and then switches to the second speed to move from the fourth execution position to the second execution position. The second execution position moves to the first execution position, and finally returns to the first speed and moves from the first execution position to the third execution position.

The embodiment of the present application divides the rated swing wind area based on the first execution position and the second execution position, so that the swing speed of the area composed of the first execution position and the second execution position is set to the second speed, and the swing speed of the remaining areas is The speed is set to first speed. It realizes optimal control of the swing speed of the horizontal guide plate within the corresponding range according to the longitudinal coverage area of the human body, so that the vertical area corresponding to the human body is swept slowly, and the non-human body area is swept quickly, improving the control accuracy and control of the indoor unit. efficiency and optimize user experience.

Based on any of the above embodiments, before determining the height range based on the first position information and the second position information of the indoor individual, it also includes: within a preset time period after the air conditioner is started, based on the radar module feedback The first location information and the second location information of the indoor individual are used to determine the preset height range.

Specifically, before step 101, within a preset time period after the air conditioner starts the working mode, the control device of the indoor unit receives the first position information and the third position information collected by the radar module for each individual in the room during this period. The second position information is based on multiple sets of position information pairs at multiple historical moments, and the height range of the individual user after being slightly stable within a certain period of time is fitted, and this range is used as the initial preset height range.

The preset height range refers to the height range in which the relative movement trajectories of indoor users within the preset time period are relatively fixed after starting the working mode. The preset height range is used to provide a comparison basis for subsequent height ranges, so as to characterize and quantify the movement status of the individual user from the side based on the relative position change of the vertical height of the individual user in the room caused by the lateral distance between the individual user and the air conditioner.

The embodiment of this application does not specifically limit the value of the preset duration.

Optionally, the preset time period needs to be much larger than the working cycle of the radar module, for example, 10 minutes.

It can be understood that after step 103, for the execution position adjustment strategy executed in this round, the height range, the first execution position and the second execution position corresponding to this round are updated and stored in memory by replacing the preset height range, The height range of this round is used as the historical height range of the next round of adjustment, providing a reference object for the adjustment strategy at the next moment.

Optionally, a fixed-length sequence can also be dynamically maintained to sequentially store the height ranges at different historical moments. When the length of the sequence reaches the fixed length value, the earliest stored historical height range is marginalized and the newly stored historical height range is added.

In the embodiment of the present application, after each adjustment, the height range is used to update and store the historical height range, and then provide the theoretical basis for the adjustment strategy of the first execution position and the second execution position next time, achieving quantitative analysis of the indoor height range based on the height range. Individual abnormal movements, and quickly determine the update of the human body area, and accordingly adjust the swing speed of the guide plate within the swing range corresponding to the human body area, so as to slow down the sweep area composed of the first execution position and the second execution position updated in real time. Swing speed, accelerate the swing speed in other areas, improve the control accuracy and currentness of the indoor unit, and optimize the user experience.

Based on any of the above embodiments, setting the first execution position and the second execution position based on the height range includes: extracting the first target position information and the second target position information from the height range.

Wherein, the first target location information is the maximum value among the first location information of all individuals, and the second target location information is the minimum value among the second location information of all individuals.

Specifically, in step 101, the control device of the indoor unit calculates the distance between any two angular displacement points from the set of angular displacement points corresponding to the height range, and uses the two angular displacement points with the largest longitudinal distance as the third first target position information and second target position information.

Among them, the first target position information and the second target position information are respectively the angular displacement points with the largest absolute angle values in the upper and lower sides separated by the air conditioner, and the distance calculation method between any two angular displacement points includes but is not limited to European Distance, Manhattan distance, Chebyshev distance, Min distance, standardized Euclidean distance, cosine similarity, Mahalanobis distance, Hamming distance or Bach distance, etc.

Optionally, the process can also be judged based on the distance from each angular displacement point in the set to the origin of the coordinate system.

For example, taking the indoor layout position of the sensing module as the origin of the coordinate system, taking the horizontal line where the sensing module is located as the X-axis, and the vertical line perpendicular to the X-axis in the horizontal plane as the Y-axis, according to The value of the The displacement points of 0) are divided into lower zone subsets. The angle displacement point with the largest angle value is extracted from the upper area subset as the first target position information, and the angle displacement point with the smallest angle value is extracted from the lower area subset as the second target position information.

Based on the first target position information and the second target position information, calculations are performed with the position information of the radar module respectively to determine the first execution position and the second execution position.

Specifically, in the coordinate system with the indoor layout position of the sensing module as the origin, the control device of the indoor unit uses the first target position information and the position information of the radar module to calculate the first execution position, and uses the second target position The second execution position is calculated from the position information and the position information of the radar module.

The embodiment of this application is based on the first target position information and the second target position information located farthest in the upper and lower zones within the height range, combined with the position information of the radar module, to calculate the first execution position relative to the radar module and the The second execution position determines the human body area based on the longitudinal coverage of the human body of multiple individuals, optimally controls the swing range of the transverse guide plate, and slows down the swing speed of the sweeping area composed of the first execution position and the second execution position. Accelerate the swing speed in other areas, improve the control accuracy and efficiency of the indoor unit, and optimize the user experience.

Based on any of the above embodiments, the yaw blade assembly includes a left yaw blade assembly and a right yaw blade assembly.

Based on the first execution position and the second execution position, adjusting the swing speed of the sway blade assembly in the rated swing wind area specifically includes:

The left yaw blade assembly is controlled to start reciprocating from the third execution position, through the first execution position and the second execution position to the fourth execution position.

The right yaw blade assembly is controlled to start reciprocating from the fourth execution position, through the second execution position and the first execution position to a third execution position.

Specifically, the yaw blade assembly can be divided into left and right sections, and a left yaw blade assembly and a right yaw blade assembly are provided. Then the third execution position and the fourth execution position can be used as the initial positions of the left yaw blade assembly and the right yaw blade assembly respectively. After controlling the left yaw blade assembly to quickly move from the third execution position to the first execution position, The swing speed is slowed down in the interval formed by the first execution position and the second execution position, and the rapid swing wind is restored during the swing to the fourth execution position. At the same time, the right lateral swing blade assembly is also controlled to move rapidly from the fourth execution position to the fourth execution position. After the second execution position, the swing speed slows down in the interval formed by the second execution position and the first execution position, and the rapid swing wind resumes during the swing to the third execution position.

The embodiment of the present application is based on controlling the left oscillating blade assembly and the right oscillating blade assembly to guide the wind in the opposite swing direction within the rated oscillating wind area, so that at any time, the left lateral oscillating blade assembly and the right lateral oscillating blade assembly can be controlled. When the components are in the same position, there is air volume output in both the upper and lower zones, improving the control accuracy and sweeping efficiency of the indoor unit and optimizing the user experience.

Based on any of the above embodiments, after determining the altitude range based on the first location information and the second location information of the indoor individual, the method further includes: based on the second location information and the location of the radar module. information and determine the scope of activities.

Specifically, after step 101, the control device of the indoor unit also periodically performs a trigonometric conversion between the second position information collected by each individual in the room and the position information of the radar module based on the radar module to obtain the corresponding The position information of the individual in the horizontal space (i.e., the X-axis) is stored in a set corresponding to the current moment to form the activity range of the indoor individual in the current period.

Based on the range of motion, a first execution angle and a second execution angle are determined.

Wherein, the first execution angle is in the left area of the air outlet, and is less than or equal to 90° relative to the horizontal plane where the radar module is located; the second execution angle is in the right area of the air outlet, And it is greater than or equal to 90° relative to the horizontal plane where the radar module is located.

Specifically, the control device of the indoor unit compares the displacement points contained in the user's current activity range with the displacement points of the preset activity range. The higher the coincidence rate of the displacement points in the two sets, the greater the displacement points between the activity range and the preset activity range. The higher the similarity between ranges.

If the similarity between the activity range and the preset activity range is less than the preset threshold, it means that the indoor individual has obvious displacement changes. According to the mapping relationship between the activity range and the execution angle, determine the distance between the two ends of the activity range. The corresponding first execution angle and second execution angle.

If the similarity between the activity range and the preset activity range is greater than or equal to the preset threshold, it means that there is no obvious displacement change of the indoor individual, then based on the preset activity range or activity range, combined with the relationship between the activity range and the execution angle The mapping relationship determines the first execution angle and the second execution angle respectively corresponding to the two ends of the current range.

The first execution angle corresponds to the first end of the movable range and is located in the left half area of the air outlet. The second execution angle corresponds to the second end of the movable range and is located in the right half area of the air outlet.

The first execution angle is the angle between the line formed by the endpoint of the indoor left area and the point where the radar module is located, taking the air conditioner layout position as the indoor dividing point, and the horizontal plane where the radar module is located. The second execution angle is the angle between the line formed by the endpoint of the right half of the indoor area and the point where the radar module is located, and the horizontal plane where the radar module is located.
