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 the activity range based on the location information of the indoor individual.

Wherein, the location information of the indoor individual is 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 activity range of the indoor individual is determined through the location information fed back in real time by the radar module, so that the area where the person is located is regarded as the effective area, and The indoor unit controls the air flow only within the effective area.

Among them, the radar module periodically collects the location information of all individuals in the room at specified time intervals and sends the location information to the 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 working mode for a period of time, the control device of the indoor unit receives the location information periodically collected by the radar module for each individual in the room, and combines the location information of multiple groups of individuals. Store it in a collection corresponding to the current moment to form the activity range of 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: When it is determined that the similarity between the activity range and the preset activity range is less than the preset threshold, set a first execution angle and a second execution angle based on the activity range.

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

It should be noted that the preset activity range refers to a set based on the location 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 included in the user's current activity range with the displacement points in the preset activity range. The higher the coincidence rate of the displacement points in the two sets, the greater the activity. The greater the similarity between the range and the preset activity range.

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 is determined respectively with both ends of the current range. The corresponding first execution angle and second execution angle.

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.

The embodiments of the present application do not specifically limit the value ranges of the first execution angle and the second execution angle.

For example, in the horizontal plane where the radar module is located, taking the position of the radar module as the origin, the angle formed by the endpoint on the left half of the horizontal line and the horizontal plane is recorded as 0°, and the angle formed by the endpoint on the right half of the horizontal line is 0°. The angle formed by the endpoint and the horizontal plane is recorded as 180°.

If the air conditioner is at the far left end of the room and the radar module is installed at the far left end of the air conditioner housing, the first execution angle can only be 90°, that is, perpendicular to the radar module, and the air cannot continue to swing to the left. In other layout situations, the first execution angle may be an acute angle or a right angle, so that the sweeping area completely includes the left side of the room.

If the air conditioner is located at the far right end of the room and the radar module is installed at the far right end of the air conditioner housing, the second execution angle can only be 90°, that is, perpendicular to the radar module and cannot continue to swing the air to the right. In other layout situations, the second execution angle may be an obtuse angle or a right angle, so that the sweeping area completely includes the right side of the room.

Step 103: Control the vertical swing blade assembly to swing left and right between the first execution angle and the second execution angle.

Specifically, in step 103, the control device of the indoor unit encapsulates the first execution angle and the second execution angle obtained in step 102 into control instructions, and sends them to the indoor unit.

The indoor unit receives and responds to the control command, and combines the first execution angle and the second execution angle to generate an execution angle range. During this working cycle, the vertical swing blade assembly is controlled to swing left and right within the execution angle range, that is, Air is supplied only to effective areas in the room where there are individual users.

The embodiment of this application monitors the individual's activity range in real time based on the radar module, sets the execution angle through the activity range decision-making, and realizes the optimal control of the swing range of the guide plate according to the occupied area, so that the first execution angle and the second execution angle can be optimally controlled. The sweep area formed by the angle is related to the area where the person is located. Regional correspondence improves the control accuracy and efficiency of indoor units and optimizes user experience.

Based on any of the above embodiments, before determining the real-time activity range based on the real-time location information of the indoor individual, it also includes:

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 location information collected by the radar module for each individual in the room during this period, and based on multiple Multiple sets of location information at historical moments are used to fit the user's individual activity range after a period of time that is slightly stable, and this range is used as the initial default activity range.

The preset activity range refers to the activity range in which the relative motion trajectories of indoor users are relatively fixed within the preset time period after the working mode is started. The preset activity range is used to provide a comparison basis for subsequent activity ranges to characterize and quantify the individual user's movement status.

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.

The embodiment of this application is based on the radar module monitoring the initial movement of indoor individuals within the preset time period after starting the working mode, and obtaining the preset activity range, and then when the activity range does not coincide with the preset activity range, The decision is made to use the current range of activities to set the execution angle, thereby optimally controlling the swing range of the guide plate according to the relatively stable occupied area, so that the sweep area composed of the first execution angle and the second execution angle is consistent with the area where people are located. Correspondence, improve the control accuracy and stability of indoor units, and optimize user experience.

Based on any of the above embodiments, after the vertical swing blade assembly is controlled to swing left and right between the first execution angle and the second execution angle, the method further includes: dynamically maintaining all the parameters based on the activity range. Describe the default activity scope.

Specifically, after step 103, for the execution angle adjustment strategy executed in this round, the corresponding activity range, first execution angle and second execution angle of this round are updated and stored in memory by replacing the default activity range. The scope of activity in this round serves as the historical scope of activity in the next round of adjustment, providing a reference for the adjustment strategy at the next moment.

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

After each adjustment, the embodiment of the present application uses the activity range to update and store the historical activity range, and then provides the theoretical basis for the adjustment strategy of the first execution angle and the second execution angle next time, achieving quantitative analysis of the indoor activity range based on the activity range. Based on individual abnormal movements, we can quickly determine the update of the occupied area and adaptively adjust the swing range of the guide plate so that the update frequency of the sweep area composed of the first execution angle and the second execution angle matches the frequency of human displacement. Improve the control accuracy and currentness of indoor units and optimize user experience.

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

Specifically, in step 101, the control device of the indoor unit calculates the distance between any two displacement points from the set of displacement points corresponding to the activity range, and uses the two displacement points with the largest distance as the first position information and Second location information.

Among them, the first position information and the second position information are respectively the farthest displacement points on the left and right sides separated by the air conditioner, and the distance calculation method between any two displacement points includes but is not limited to Euclidean 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 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 X-axis value is 0 for boundary division. In the displacement point set corresponding to the activity range, the displacement points with the X-axis value less than 0 are divided into the left area sub-set, and the displacement points with the X-axis value less than 0 are divided into the right area sub-set. gather. And the displacement point with the largest absolute value of the X-axis value is extracted from the two subsets respectively as the first position information and the second position information.

Based on the first position information and the second position information, calculation is performed with the position information of the radar module respectively to determine the first execution angle and the second execution angle.

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 position information and the position information of the radar module to calculate the position in the coordinate system. For the first execution angle in the third quadrant, the second execution angle in the fourth quadrant of the coordinate system is calculated using the second position information and the position information of the radar module.

The embodiment of the present application is based on the first position information and the second position information located farthest in the left and right areas within the activity range, combined with the position information of the radar module, to calculate the first execution angle and the second execution angle relative to the radar module. The execution angle realizes the determination of the occupied area based on the displacement points of multiple bodies, and optimally controls the swing range of the guide plate, so that the sweeping area composed of the first execution angle and the second execution angle corresponds to the area where the people are, improving the performance of the indoor unit. Control accuracy and efficiency to optimize user experience.

Based on any of the above embodiments, the vertical swing leaf assembly includes an upper vertical swing leaf assembly and a lower vertical swing leaf assembly.

The upper vertical swing blade assembly is controlled to start swinging back and forth from the first execution angle to the second execution angle.

Specifically, the vertical swing leaf assembly can be divided into upper and lower sections, and is provided with an upper vertical swing leaf assembly and a lower vertical swing leaf assembly. In the process of controlling the swing of the vertical swing leaf assembly, the first execution angle and the second execution angle can be used as the initial positions of the upper vertical swing blade assembly and the lower vertical swing blade assembly respectively, and the upper vertical swing blade assembly is controlled by the first While the execution angle swings back and forth toward the second execution angle, the lower vertical swing blade assembly is also controlled to swing back and forth from the second execution angle to the first execution angle.

The embodiment of the present application is based on controlling the upper vertical swing blade assembly and the lower vertical swing blade assembly. Within the sweep range formed by the first execution angle and the second execution angle, the wind is guided in the opposite swing direction, and the wind can be guided at any time. When the upper vertical swing leaf assembly and the lower vertical swing leaf assembly are in the same position, there will be air volume output in both left and right areas, 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 activity range based on the indoor individual's position information, it further includes: determining the individual's height position information based on the indoor individual's shape information fed back by the radar module.

It should be noted that in the coordinate system with the radar module position as the origin, the vertical line where the radar module is located is used as the Z axis to establish a complete three-dimensional coordinate system.

Specifically, after step 101, the control device of the indoor unit can also receive feedback from the radar module. Based on the fed-in indoor individual shape information, the longitudinal height corresponding to the Z-axis of each individual silhouette is extracted and calculated as the height position information of the corresponding individual.

It can be understood that all current height position information is weighted and averaged according to the number of individuals in the room, and the average value obtained can represent the overall height level of the indoor individuals.

Based on the height position information and the position information of the radar module, a critical angle is determined.

If it is determined that the air conditioner is in the heating mode, the oscillating blade assembly is controlled to guide the air downward at an inclined angle at a third execution angle.

If it is determined that the air conditioner is in the cooling mode, the oscillating blade assembly is controlled to tilt downward at a fourth execution angle.

Wherein, the third execution angle is smaller than the critical angle relative to the horizontal plane where the radar module is located. The fourth execution angle is greater than the critical angle relative to the horizontal plane where the radar module is located.

Specifically, the control device of the indoor unit calculates the angle between the straight line connecting the individual head and the radar module and the XY plane in the coordinate system based on the height position information of the indoor individual and the position information of the radar module. , take this value as the critical angle.

If the control device of the indoor unit determines based on the operating information fed back by each component of the air conditioner that the started working mode is the heating mode, the value greater than the critical angle will be used as the third execution angle, and the oscillating blade assembly will be controlled to move to the third execution angle. Angle, under the action of a larger angle, the air is directed downwards, so that the hot air with a smaller density is transported to the bottom space of the room.

If the control device of the indoor unit determines based on the operating information fed back by each component of the air conditioner that the started working mode is the cooling mode, the value smaller than the critical angle will be used as the fourth execution angle, and the oscillating blade assembly will be controlled to move to the fourth execution angle. , under the action of a larger angle, the air is guided upward but does not blow directly on the head.

The embodiment of the present application is based on the real-time monitoring of the body shape information of indoor individuals based on the radar module to determine the height position information of the individual in the room. The height position information is used to decide and control the execution angle of the oscillating blade assembly in different working modes, which can be used in refrigeration. Avoid cold wind blowing directly on the head when heating, and avoid the "hot head and cold feet" situation caused by the accumulation of hot air above the room during heating, improve the control accuracy of the indoor unit, and optimize the user experience.
