[0027] See also Figure 1-3 , which provides a flow chart of the intelligent control method of the exhaust device 10, a structural schematic diagram of the exhaust system 99, and an application environment schematic diagram for an embodiment of the present invention. The intelligent control method of the exhaust device 10 can be applied to, but is not limited to, indoor areas such as offices and residences to control the swing and wind speed of the exhaust device 10. The exhaust device 10 can be a vertical air conditioner or a supply fan integrated with a bathroom heater. The exhaust system 99 includes a radar sensor 20 and an exhaust device 10. For example, the exhaust device 10 includes a main controller 11 and a guide vane that can rotate back and forth and is used to supply air. There can be multiple radar sensors 20, and multiple radar sensors 20 are arranged on the ceiling of the living room and are wirelessly connected to the exhaust device 10 so that the detection area covers all areas in the living room. Multiple radar sensors 20 can also be arranged in the exhaust device 10 and are connected to the exhaust device 10 by wired or wireless means. For example, they are arranged around the exhaust device 10 so that the detection area covers all areas in the living room, which is not limited here. The radar sensor 20 is used to monitor the number and movement trajectory of users around the exhaust device 10. Figure 3 Taking the application scenario shown as an example, when the application area is a living room, the living room is a circular area and includes 20 sector areas with a central angle of 15°, and the exhaust device 10 is placed in the center of the living room. The intelligent control method of the exhaust device 10 includes the following steps.

[0028] Step S10: Detect the user using the radar sensor 20. Specifically, the main controller 11 connected to the radar sensor 20 is used to control the radar sensor 20 to detect whether there is a user in the detection area. In this embodiment, the detection area covers all areas in the living room. The radar sensor 20 sends a pulse signal to the detection area and receives the reflected pulse echo signal. The radar sensor 20 determines whether there is a human micro-motion signal in the pulse echo signal based on the pulse echo signal and the pulse signal. The specific detection steps of the human micro-motion signal are described in detail below. If there is, it proves that there is a user in the detection area. If not, it proves that there is no user in the detection area.

[0029] Step S20: When a user is detected, a radar signal related to the user is obtained from the radar sensor 20. Specifically, when the radar sensor 20 detects a micro-motion signal of the user, the main controller 11 obtains a radar signal related to the user from the radar sensor 20. In this embodiment, the radar signal is used to indicate the location where the target appears. The radar signal can be two-dimensional coordinate information of a human body micro-motion signal. For example, a coordinate system is established with the exhaust device 10 as a coordinate point. When the user moves, the two-dimensional coordinate information is multiple. When the user is stationary, the two-dimensional coordinate information is one.

[0030] Step S30: Calculate the activity area of ​​the user based on the user's related radar signals. Specifically, the radar sensor 20 calculates the user's activity area based on the user's related pulse signals and pulse echo signals. The activity area is the range of the area where the user may be active. In other words, the activity area is the area along the rotation path of the exhaust device 10 toward the current position of the user. For example, the user can be stationary, then the activity area is a location point, that is, the two-dimensional coordinate information can be one. The user can also be mobile, then the activity area is an area, for example, the two-dimensional coordinate information is multiple, see Figure 3 The A2 sector area is within the range of 0-15° counterclockwise along the right side L, and the central angle corresponding to the A2 sector area is 30°.

[0031] Step S40: Plan an air supply area according to the user's activity position, and the air supply area faces the user's activity area. Specifically, the main controller 11 plans an air supply area according to the user's activity position, and the air supply area only needs to face the user's activity area. The central angle of the air supply area can be adjusted according to actual conditions and is not limited here. In this embodiment, the air supply area can be an area of ​​0-15° counterclockwise to the right. For details, please refer to Figure 3 Middle C1 area.

[0032] Step S50: When the air supply direction of the exhaust device 10 is not toward the air supply area, the air supply direction of the exhaust device 10 is adjusted according to the air supply area so that the exhaust device 10 supplies air toward the air supply area.

[0033] In this embodiment, the exhaust device 10 is a vertical air conditioner. The main controller 11 calculates the current air supply direction of the exhaust device 10 according to the angle of the air guide blade 12, and determines whether the air supply direction of the exhaust device 10 is located in the air supply area. If it is not located in the air supply area, the rotation path of the air guide blade 12 is planned according to the air supply area and the current air supply direction, so that the exhaust device 10 supplies air toward the air supply area. For example, the air guide blade 12 includes a horizontal air guide blade arranged in the horizontal direction and a vertical air guide blade arranged in the vertical direction. The vertical air conditioner is adjusted by the horizontal air guide blade to supply air to the upper, middle and lower areas directly in front. The vertical air conditioner is adjusted by the vertical air guide blade to supply air to the left, middle and right areas.

[0034] In some other embodiments, the exhaust device 10 may be an exhaust component 12, such as a fan. The fan changes the air supply direction by shaking its head. Adjusting the air supply direction of the exhaust device 10 according to the air supply area includes planning a rotation path according to the air supply area, and controlling the movement of the exhaust component 12 according to the rotation path so that the exhaust component supplies air toward the air supply area. The rotation path may be a clockwise rotation path or a counterclockwise rotation path. For example, see Figure 3 , the current orientation position of the exhaust assembly 12 is rightward L, the air supply area is the area 0-15° counterclockwise from the rightward, the current orientation position of the exhaust assembly 12 is not located in the air supply area, the main controller 11 plans the rotation path of the exhaust assembly 12 according to the current orientation position L and the area 0-15° counterclockwise from the rightward of the air supply area to swing from the orientation position L to the C1 area in a clockwise or counterclockwise direction, so that the exhaust assembly 12 is directed toward the air supply area. Step S50 includes steps S501-S503.

[0035] Please see Figure 4 and 5 , which is a flow chart and schematic diagram of planning the rotation path of the exhaust component 12 provided by an embodiment of the present invention. Step S501 specifically includes the following steps.

[0036] Step S51: acquiring the first clockwise rotation path M1 and the second counterclockwise rotation path M2 of the exhaust assembly 12 according to the air supply area. Specifically, the main controller 11 acquires the first clockwise rotation path M1 and the second counterclockwise rotation path M2 of the exhaust assembly 12 according to the air supply area.

[0037] Step S52: Control the exhaust assembly 12 to rotate along the first path or the second path to the air supply area. Specifically, the main controller 11 controls the exhaust assembly 12 to rotate along the first path M1 or the second path M2 to the air supply area.

[0038] Planning the rotation path of the exhaust assembly 12 according to the air supply area also includes the following steps.

[0039] Step S511: using the radar sensor 20 to detect whether there is an obstacle on the first path or the second path. Specifically, the main controller 11 uses the radar sensor 20 to detect whether there is an obstacle on the first path M1 or the second path M2.

[0040] Step S513: When the exhaust assembly 12 rotates along the first path and the radar sensor 20 detects that there is an obstacle on the first path, the distance of the obstacle relative to the exhaust assembly 12 is detected. Specifically, the main controller 11 controls the exhaust assembly 12 to rotate along the first path M1, and when the radar sensor 20 detects that there is an obstacle Z1 on the first path, the distance of the obstacle Z1 relative to the exhaust assembly 12 is detected.

[0041] Step S515: When the distance is less than a preset value, the exhaust assembly 12 is controlled to rotate along a second rotation path. Specifically, when the distance between the obstacle Z1 and the exhaust assembly 12 is less than a preset value, wherein the preset value can be set according to actual conditions and is not limited here; for example, the preset value is 10 cm. The exhaust assembly 12 is controlled to rotate along the second rotation path.

[0042] Step S517: When the exhaust assembly 12 rotates along the second path and the radar sensor 20 detects that there is an obstacle on the second path, detect the distance of the obstacle relative to the exhaust assembly 12. Specifically, when the main controller 11 controls the exhaust assembly 12 to rotate along the second path, upon receiving a signal that the radar sensor 20 detects that there is an obstacle Z2 on the second path, the radar sensor 20 is used to detect the distance of the obstacle Z2 relative to the exhaust assembly 12.

[0043] Step S519: When the distance is less than the preset value, the exhaust assembly 12 is controlled to rotate along the first rotation path; or when there are obstacles in both the first path and the second path and the distance between the obstacle and the exhaust assembly 12 is less than the preset value, the exhaust assembly 12 is controlled to stop rotating and reduce the wind speed. Specifically, when the main controller 11 receives the information that the distance of the obstacle Z2 detected by the radar sensor 20 relative to the exhaust assembly 12 is less than the preset value, wherein the preset value can be set according to the actual situation and is not limited here; the exhaust assembly 12 is controlled to rotate along the first rotation path to the air supply area; or when there are obstacles Z1 and Z2 in both the first path and the second path, respectively, and the distance between the obstacle Z1 and the obstacle Z2 and the exhaust assembly 12 is less than the preset value, the main controller 11 controls the exhaust assembly 12 to stop rotating and reduce the wind speed.

[0044] Step S503: Control the exhaust assembly 12 to rotate along the rotation path to supply air to the air supply area. Specifically, the main controller 11 controls the exhaust assembly 12 to rotate along the rotation path so that the exhaust assembly 12 supplies air toward the air supply area. In this embodiment, the main controller 11 controls the exhaust assembly 12 to swing in a clockwise direction from the direction position L (see FIG. Figure 5 The exhaust assembly 12 is controlled to rotate along the rotation path to supply air to the air supply area, specifically including the following steps.

[0045] Step S5031: When the exhaust device 10 faces the air supply area, the exhaust assembly 12 is controlled to stop rotating. Specifically, when the main controller 11 controls the exhaust assembly 12 to swing clockwise from the direction position L (see Figure 5 M1 path) or swing counterclockwise (see Figure 5 The exhaust assembly 12 is directed toward the air supply area, and the main controller 11 controls the exhaust assembly 12 to stop rotating so that the exhaust assembly 12 can blow air toward the air supply area.

[0046] Step S5033: When the exhaust device 10 is not facing the air supply area, the exhaust assembly 12 is controlled to reciprocate clockwise and counterclockwise relative to the air supply area. Specifically, when the main controller 11 detects that the exhaust device 10 is not facing the air supply area, the exhaust assembly 12 is controlled to reciprocate clockwise and counterclockwise relative to the air supply area so that the exhaust assembly 12 moves toward the air supply area. Thereby, the air supply to the air supply area is realized by rotation.

[0047] In the above embodiment, an air supply area facing the user is planned, and when the exhaust component 12 is not facing the air supply area, the exhaust component 12 is controlled to move to the air supply area, thereby ensuring that the exhaust component 12 moves to the air supply area and supplies air towards the user's position in the air supply area.

[0048] In some feasible embodiments, the intelligent control method of the exhaust device 10 further includes the following steps.

[0049] Step S701: When the exhaust device supplies air toward the air supply area, the real-time gesture of the user is collected.

[0050] Step S703: When the user's real-time gesture is identified as a preset reverse blowing gesture, the exhaust device is controlled to blow air in a direction away from the air supply area. For example, the preset direction blowing gesture is that the forearm is kept parallel to the ground, the palm is naturally downward, and the palm moves back and forth around the forearm in two directions, forward and backward.

[0051] In the above embodiment, the air can be blown in a direction away from the user through a specific gesture, thereby preventing the user from catching a cold due to excessive blowing.

[0052] In some other feasible embodiments, the swing mode of the exhaust device 10 can also be a reverse blowing mode. The reverse blowing mode is when the user's current position is outside the blowing area. The method further includes the following steps.

[0053] Step S201: In response to user operation, start the forward blowing mode or the reverse blowing mode.

[0054] Please see Figure 6-8 , which are respectively a flow chart after the exhaust device 10 enters the tracking mode and a schematic diagram of the air supply area when the user is in the first position and the second position. In some other feasible embodiments, the method also includes the following steps.

[0055] Step S301: When only one user is detected and a tracking instruction from the user is received, the current position of the user is obtained in real time. Specifically, when the main controller 11 receives a tracking instruction from the user, it controls the radar sensor 20 to obtain the current position of the user in real time. The tracking instruction may be a physical button set on the main controller 11, generated by pressing the physical button, or a mapping table of gestures and operation instructions pre-set in the radar sensor 20, where the radar sensor 20 recognizes the gesture to generate a corresponding tracking instruction and sends it to the main controller 11, or a touch screen connected to the main controller 11 displays a virtual tracking button, which is generated by touching the virtual tracking button, which is not limited here. The radar sensor 20 obtains the current position of the user and sends the position to the main controller 11. For example, the radar sensor 20 obtains that the current position of the user is in the first position A1, and sends the first position A1 to the main controller 11; wherein the first position A1 is in the direction of 22° counterclockwise along the right side L. The radar sensor 20 acquires the user's current position at the second position A4 in the next cycle, and sends the second position A4 to the main controller 11; wherein the second position A4 is in the direction of 6° counterclockwise along the right side L.

[0056] Step S303: Plan the air supply area in real time according to the current position of the user. Specifically, the main controller 11 plans the blowing area in real time according to the current position of the user. In this embodiment, the current position of the user can change, and the blowing area also changes with the change of the current position of the user. For example, when the main controller 11 receives the user position obtained by the radar sensor 20 and is in the current first position A1, the planned blowing area is A3. When the main controller 11 receives the user position obtained by the radar sensor 20 and is in the current second position A4, the planned blowing area is A5. In some other embodiments, the current position of the user can be fixed, and the blowing area is also fixed. For example, the main controller 11 receives the user position obtained by the radar sensor 20 and is always in the first position A1, and the main controller 11 plans the blowing area to be A3.

[0057] Step S305: planning an air supply path of the exhaust device according to the air supply area so that the air supply direction of the exhaust device is toward the blowing area. Specifically, step S305 includes steps S3051 and S3052.

[0058] Step S3051: Plan the rotation path of the exhaust assembly 12 according to the air supply area. Specifically, the main controller 11 plans the rotation path of the exhaust assembly 12 according to the air supply area. In this embodiment, when the user's current position is A1 and the air supply area is A3, the rotation path of the exhaust assembly 12 can be clockwise from A1 to A3 or counterclockwise from A1 to A3, and the rotation path of clockwise from A1 to A3 with a shorter rotation distance can be selected.

[0059] Step S3052: Control the exhaust assembly 12 to rotate along the rotation path to supply air to the air supply area. Specifically, the main controller 11 controls the exhaust assembly 12 to rotate along the rotation path from A1 to A3 clockwise to make the exhaust assembly 12 supply air to the air supply area A3.

[0060] In the above embodiment, the tracking mode is entered by receiving the user's tracking command, the user's position is acquired in real time using the radar sensor 20 and the air supply area is planned according to the user's position, and the exhaust component 12 is controlled to move to the air supply area for air supply, so that during the user's movement, the exhaust component 12 can always avoid the user's activity area for air supply and ensure indoor air circulation.

[0061] In some feasible embodiments, the intelligent control method of the exhaust device 10 further includes the following steps.

[0062] Step S401: When the exhaust device 10 is in the forward blowing mode, the micro-motion signal of the human body is detected. Specifically, when the exhaust device 10 is in the forward blowing mode, the radar sensor 20 is used to detect whether there is a micro-motion signal of the human body in its detection area. In this embodiment, the radar sensor 20 transmits a pulse signal toward its detection area, and receives the reflected pulse echo signal, and judges whether the pulse echo signal contains only the micro-motion signal or only the interference signal according to the pulse echo signal and the pulse signal, and then judges whether there is a micro-motion signal of the human body. Among them, the micro-motion signal of the human body is the heart rate signal of the human body, and the interference signal can be generated by the clothes swinging with the wind when the exhaust component 12 blows towards the clothes of the human body, or it can be generated by the wind blowing the clothes or curtains of the human body when the doors and windows of the living room are opened, or it can be generated by the swinging objects placed in the living room. The radar sensor 20 distinguishes the micro-motion signal and the interference signal according to the difference in amplitude or duration between any two cycles in the pulse echo signal, thereby improving the accuracy of whether there is a micro-motion signal of the human body. For example, the difference between the pulse echo signal and the pulse signal is calculated to obtain a vibration signal. When the difference in duration between any two cycles in the vibration signal is greater than a preset value, the vibration signal is determined to be a human body micro-motion signal.

[0063] Step S403: When a human body micro-motion signal is detected, the wind speed of the exhaust component 12 is reduced or the exhaust device 10 is controlled to enter a reverse blowing mode. Specifically, when the radar sensor 20 detects a human body micro-motion signal, the main controller 11 controls the exhaust component 12 to reduce the wind speed or controls the exhaust component 12 to enter a reverse blowing mode.

[0064] In the above embodiment, the forward blowing mode is initially set. When a micro-motion signal of a human body is detected in the air supply area, the air supply speed is reduced or the air supply mode is changed to a reverse blowing mode, thereby avoiding the exhaust device 10 from blowing air toward the human body at a higher wind speed as much as possible, making the human body feel more comfortable.

[0065] In some feasible embodiments, the intelligent control method of the exhaust device 10 further includes the following steps.

[0066] Step S501: When the exhaust device 10 is in the forward blowing mode, the radar sensor 20 is used to obtain the user's age characteristics. Specifically, when the exhaust device 10 is in the forward blowing mode, the main controller 11 uses the radar sensor 20 to obtain the user's age characteristics. The age characteristics are characteristics related to age, for example, the age characteristics can be height, waist circumference or arm length. The radar sensor 20 can detect the length, width and outline of the human body and objects, and then identify the height, waist circumference or arm length.

[0067] Step S503: Identify the user's age according to the user's age characteristics. Specifically, the main controller 11 identifies the user's age according to the user's age characteristics. In this embodiment, a mapping table of height and age may be pre-stored, and the mapping table may be set according to actual conditions. The main controller 11 receives the height of the user identified by the radar sensor 20, and identifies the user's age according to the height.

[0068] Step S505: When the user's age is younger than the preset age, the reverse blowing mode is adjusted to control the exhaust component 12 to sweep air or directional air to avoid the user's position. Specifically, the main controller 11 determines the user's age and the preset age for calculation. When the user's age is younger than the preset age, the main controller 11 controls the exhaust component 12 to adjust to the reverse blowing mode, and the exhaust component 12 supplies air to avoid the user. The air supply method can be sweeping air to avoid the user or directional air to avoid the user.

[0069] In the above embodiment, the age characteristics of the user are obtained by the radar sensor 20, and the main controller 11 identifies the age of the user based on the age characteristics, and adjusts to the reverse blowing mode when the age of the user is younger than the preset age. Therefore, when the radar sensor 20 identifies a user whose age is younger than the preset value, the exhaust component 12 is prevented from blowing air toward the user, thereby preventing younger users from catching a cold due to continuous blowing.

[0070] In some feasible embodiments, the intelligent control method of the exhaust device 10 further includes the following steps.

[0071] Step S601: When the radar sensor detects multiple users, the current gesture of each user is collected.

[0072] Step S603: When a real-time gesture of one of the multiple users is identified as a preset gesture, the direction pointed by the real-time gesture of the user is extracted and the pointed area is determined according to the pointed direction. In this embodiment, the preset gesture refers to a gesture of the user pointing to a certain area in the horizontal direction. For example, the palm and forearm may be kept horizontal and only the index finger is extended toward a certain area in the room. When the radar sensor detects a preset gesture, the area pointed by the user is calculated according to the extension direction of the finger.

[0073] Step S605: When the air supply area of ​​the exhaust device is not facing the area pointed by the real-time gesture of the user, the exhaust device is controlled to supply air to the area pointed by the real-time gesture of the user, so that any one of the multiple users can achieve the effect of supplying air to the area pointed by the real-time gesture.

[0074] In some feasible embodiments, the intelligent control method of the exhaust device 10 further includes the following steps.

[0075] Step S701: When the radar sensor detects a user, the volume of the room where the user is located is obtained and the motion state of the user in the room is detected. The radar sensor obtains the length, width and height of the user's room and can determine the volume of the user's room. The motion state of the user in the room includes a moving state and a stationary state, which can be obtained based on the user's displacement per unit time.

[0076] Step S703: adjusting the power of the exhaust device according to the volume and the motion state. When the volume is relatively large and the user is in motion, the power of the exhaust device is increased.

[0077] In the above embodiment, when the volume of the user's room is relatively large and the user is in motion, increasing the power of the exhaust device can make the user feel the coolness more quickly.

[0078] Please refer to Fig. 9, which is a schematic diagram of the structure of the exhaust device 10 provided in an embodiment of the present application. The exhaust device 10 includes a main controller 11 and an exhaust component 12, and the main controller 11 includes a processor 801 and a memory 802. The memory 802 is used to store the intelligent control program instructions of the exhaust device 10, and the processor 801 is used to execute the intelligent control program instructions of the exhaust device 10 to implement the intelligent control method of the exhaust device 10.
