Description

TECHNICAL FIELD

[0001] The application belongs to the field of smart home, and specifically relates to an air conditioner air outlet partition flow guide control system and method. BACKGROUND

[0002] In the existing air conditioning system, although basic temperature regulation and wind direction control have been realized, most systems still lack intelligent and personalized functions. Traditional air conditioning systems often only adjust the temperature and wind speed uniformly for the entire room, and cannot provide precise personalized air conditioning services according to the actual needs and positions of users.

[0003] With the continuous development of smart home technology, more and more families begin to pursue more intelligent and personalized air conditioning experiences. Most of the current household air conditioners are split air conditioners. A split air conditioner usually includes an air conditioner indoor unit, an air conditioner outdoor unit, and an air conditioner control system. Most existing air conditioner control systems lack effective user identification and location tracking technology, and cannot accurately adjust the air supply parameters of the air conditioner according to the identity information, position, and environmental preferences of the user. This results in users often being unable to obtain the best comfort and energy-saving effect when enjoying air conditioning services. Some high-end air conditioning systems are equipped with image recognition and voice recognition technology, but these technologies can only realize simple user identity recognition and voice control functions, and cannot intelligently adjust the air conditioning partition flow according to the actual needs and positions of users.

[0004] In summary, how to improve the partition flow level of split air conditioners has become a problem that needs to be solved by technical personnel in the field. Therefore, it is necessary to propose an air conditioner air outlet partition flow guide control system and method. SUMMARY

[0005] In order to solve the above problems, the purpose of the present application is to provide an air conditioner air outlet partition flow guide control system and method, which realizes accurate identification and tracking of user positions, identity information, and environmental preferences by integrating several air outlet, temperature regulation cavity, image sensor, pickup microphone, and control unit intelligent components.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An air conditioner vent zoned airflow control system includes an indoor air conditioner unit. The bottom of the indoor air conditioner unit's air outlet is connected to several independent air outlets and corresponding temperature-regulating chambers. Each air outlet's inner wall is rotatably connected to several vertical and horizontal swing plates. Each vertical and horizontal swing plate has a linkage rod on one side, and both the vertical and horizontal swing plates are rotatably connected to the linkage rod. The inner wall of the air outlet has vertical and horizontal swing grooves. Motors are fixedly connected to the inner walls of one end of the vertical and horizontal swing grooves. The output shafts of the motors are fixedly connected to lead screws, and nut bases are threaded onto the lead screws. The linkage rods are fixedly connected to the nut bases in the corresponding directions. A small fan is fixedly connected to the bottom of each temperature regulating chamber. A fresh air inlet is also provided in the temperature regulating chamber. The input end of the fresh air inlet extends to the outside and a filter screen is detachably connected to the inner wall of the input end. A guide plate is fixedly connected to the connection between the temperature regulating chamber and the air outlet. A temperature sensor and a wind speed sensor are fixedly connected to the inner wall of the guide plate.

[0007] The indoor unit of the air conditioner integrates an image sensor, a microphone, and a control unit. The motor, temperature sensor, and wind speed sensor are all connected to the control unit. The control unit is used to adjust the air volume and fresh air volume of the indoor unit near the air outlet based on the user's identity information, location information, user's preset environmental preferences, and whether the user is using a mobile terminal, and to mix the air evenly in the temperature control cavity to control the supply air temperature. It also controls the wind speed by adjusting the fan speed and controls the swing angle of the up and down swing plate and the left and right swing plate by the motor.

[0008] Furthermore, it also includes a data acquisition module, which is signal-connected to the data interaction device; the data acquisition module is used to obtain the connection status and data interaction volume between the user's mobile terminal and the data interaction device, and the data acquisition module is connected to the control unit;

[0009] If the amount of data interaction is lower than the preset threshold, including long periods without data transmission or interaction frequency lower than the preset threshold, it is determined that the user is in a low-activity state although in the area; if the amount of data interaction is higher than the preset threshold, including frequent data transmission or interaction frequency higher than the preset threshold, it is determined that the user is actively engaged in activities in the area.

[0010] Furthermore, the control unit includes a wireless communication module, an image acquisition module, a location acquisition module, and an air outlet control module. The acquisition methods are divided into image acquisition and non-image acquisition. In the image acquisition method, the wireless communication module is used to receive signals sent by the user's mobile terminal, and at the same time obtain the user's location information and identity information, and transmit the user's location information and identity information to the air outlet control module.

[0011] Further, the image acquisition module is configured to acquire images of the image sensor coverage area to obtain acquisition images, and identify a person object in the acquisition images based on a convolutional neural network to obtain identity information and a user state of the person object, and transmit the identity information and the user state to the position acquisition module.

[0012] Further, the position acquisition module is configured to identify the person and the position based on the acquisition image data provided by the image acquisition module and the convolutional neural network, to obtain position information of the user in the image sensor coverage area, and transmit the identity information, the user state and the position information to the air outlet control module.

[0013] Further, the air outlet control module is configured to automatically adjust the temperature and the wind speed near the air outlet, and the swing angle of the up-down swing plate and the left-right swing plate, according to the identity information, the user state and the position information transmitted by the wireless communication module, the image acquisition module and the position acquisition module, and the environmental preferences preset by the user, the environmental preferences including indoor air temperature, wind speed and low temperature tolerance under different working conditions, the air outlet control module being preset with a straight blowing mode and an inclined blowing mode, the straight blowing mode being a straight blowing mode, and the inclined blowing mode being a blowing mode with a deviation of 10°.

[0014] Further, when the wireless communication module extracts the connection between the user mobile terminal and the data interaction device by a non-image acquisition method, the user identity information and the user position are obtained, the data interaction amount between the user mobile terminal and the data interaction device is obtained, it is judged whether the user is using the mobile terminal normally, the user state is obtained, and the data information is sent to the air outlet control module.

[0015] Further, when the sound pickup microphone detects that the audio device is used, it is judged whether the user is normally using the corresponding audio device, the user state is obtained, the position is judged according to the preset audio device position map, and the data information is sent to the air outlet control module.

[0016] Further, when the sound pickup microphone detects the door opening and closing sound and judges that the user enters the room at this time, the control unit performs identity judgment, if the data interaction device detects an increase in the connection end, it is judged that the user carries a mobile terminal, then the identity information and the position information are obtained directly through the wireless communication module; if the data interaction device does not detect an increase in the connection end, it is judged that the user does not carry a mobile terminal, then the data amount change of the mobile terminal in the whole family range is detected through the routing device to assist in judging the identity information and the position information; if there is no data amount change of the mobile terminal, the user identity cannot be assisted to be judged, the control unit will activate the image sensor again to acquire and judge to confirm the user identity and the position information, and the data information is sent to the air outlet control module.

[0017] A control method for air outlet partition flow guiding of an air conditioner is as follows:

[0018] Step one, image acquisition: capture the image of the covered area through the image sensor, and identify the person and obtain the identity information through the convolutional neural network.

[0019] Step two, wireless analysis: when the person and identity information cannot be accurately identified through the image acquisition mode, the identity information, location information, and connection state and data interaction between the user's mobile terminal and the routing device are obtained through the wireless communication module and the routing device.

[0020] Step three, non-image acquisition: when the user's mobile terminal and the routing device are connected through the non-image acquisition method, the user's identity information and location are obtained, and the air temperature and wind speed of the air outlet and the swing angle of the swing plate are automatically adjusted.

[0021] Step four, audio acquisition: when the user enters the room and triggers the audio device, identity judgment is performed. If the user carries a mobile terminal, the identity information is directly obtained; if not, the change in mobile terminal data volume is detected through the routing device to assist in identity judgment.

[0022] Step five: integrity verification of acquisition: if the user's identity cannot be assisted in judgment through the non-image acquisition method, return to step one to activate the image sensor again for acquisition and judgment until the user's identity recognition is completed.

[0023] Step six, air outlet control: according to the user's location information, identity information, environmental preferences, and whether the user is using the mobile terminal or other devices normally, the air temperature and wind speed of the air outlet and the swing angle of the swing plate are automatically adjusted through the air outlet control module.

[0024] The above scheme realizes the following principles and beneficial effects:

[0025] Basic principle: based on integrated image sensor, pickup microphone and control unit, the control unit captures the image of the covered area through the image sensor, and uses the convolutional neural network to realize accurate identification and tracking of user identity information, location and environmental preferences. Based on image recognition, this scheme improves the reliability and accuracy of user identity information recognition by adding non-image acquisition, audio acquisition and acquisition integrity verification.

[0026] Meanwhile, the location information and identity information of the user, the connection state and data interaction amount between the user's mobile terminal and the routing device are acquired through the wireless communication module and the routing device. Based on these information and the design of the air outlets and the temperature adjusting cavity, the control unit can automatically adjust the temperature and air speed of each air outlet, as well as the up-down and left-right swing angles of the swing plate, so as to realize accurate flow guiding control on different areas. Moreover, the input end of the fresh air outlet extends to the outside (i.e. outdoor), so that fresh air from the outside can be introduced in the process of air mixing in the temperature adjusting cavity, thereby reducing the carbon dioxide concentration in the room and improving the air quality in the room.

[0027] Advantages:

[0028] 1. The system can automatically adjust the temperature and air speed of the air outlet near the user according to the accurate recognition of the user's identity and location information, so as to ensure that the air conditioning service in the area where the user is located is more in line with the actual needs of the user, thereby improving the comfort of the user.

[0029] 2. The system can intelligently adjust the air conditioning zoning and flow guiding according to the actual needs and location of the user, so as to realize on-demand cooling or heating, avoid unnecessary energy waste, improve the energy efficiency ratio of the air conditioner, and realize energy saving and consumption reduction.

[0030] 3. The system integrates various intelligent components, so as to realize real-time tracking and automatic adjustment of the identity information, user location and environmental preferences, realize intelligent management, and improve the intelligent control level of the air conditioning system.

[0031] 4. The control unit of the system is pre-set with the environmental preferences of the identity information of the person object, including temperature, air speed, low temperature tolerance, etc., so as to accurately adjust according to the personalized needs of the user and provide personalized air conditioning service.

[0032] 5. The system can be flexibly configured and adjusted according to the actual needs of the user, such as not using the image acquisition mode for privacy consideration, acquiring user information through a non-image acquisition mode, and judging the identity through audio acquisition, so as to improve the flexibility and adaptability of the system.

[0040] The following detailed description illustrates the specific implementation method:

[0041] Example 1

[0042] As attached Figures 1-6 As shown: A three-zone airflow control system for an air conditioner outlet includes an indoor unit 1. The bottom of the air outlet of the indoor unit 1 is connected to several air outlets 3 and corresponding temperature control chambers 10. Each air outlet 3 has several vertical swing plates 5 and horizontal swing plates 6 rotatably connected to its inner wall. Each vertical and horizontal swing plate 5 and horizontal swing plate 6 has a linkage rod 12 on one side. The vertical and horizontal swing plates 5 and 6 are rotatably connected to the linkage rod 12. The inner wall of the air outlet 3 has vertical and horizontal swing grooves 14. A motor 11 is fixedly connected to the inner wall of one end of each swing groove 14 by screws. The output shaft of each motor 11 is fixedly connected to a lead screw 15 (in actual use, the motor's output shaft is directly coaxially fixed to the input shaft of the reducer). The output shaft of the reducer is fixed to the lead screw (although many products now integrate the motor and reducer; this embodiment uses the integrated product). The lead screw 15 is threaded with a nut base 13, and the linkage rod 12 is fixedly connected to the nut base 13 in the corresponding direction by screws. A small fan 9 is fixedly connected to the bottom of each temperature regulating chamber 10 by bolts. A fresh air inlet is also provided in the temperature regulating chamber 10. The input end of the fresh air inlet extends to the outside (specifically, a duct is provided at the fresh air inlet, one end of which is connected to the fresh air inlet, and the other end is connected to the outside). A filter screen 8 is detachably connected to the inner wall of the input end. A guide plate 7 is fixedly connected to the connection between the temperature regulating chamber 10 and the air outlet 3 by screws. A temperature sensor and a wind speed sensor are embedded in the inner wall of the guide plate 7.

[0043] The air conditioner indoor unit 1 is integrated with an image sensor 2, a pickup microphone 4 and a control unit, and further comprises a data acquisition module connected with a data interaction device; the data acquisition module is used to acquire the connection state and data interaction amount between the user mobile terminal and the data interaction device; if the data interaction amount is lower than a preset threshold, including long-time no data transmission or interaction frequency lower than a preset threshold, it is judged that the user is in a low activity state (for example, sleep state) although in the area. If the data interaction amount is higher than the preset threshold, including frequent data transmission or interaction frequency higher than the preset threshold, it is judged that the user is in an active activity in the area (for example, awake state). The data acquisition module, the motor 11, the temperature sensor and the wind speed sensor are connected with the control unit.

[0044] The control unit comprises a wireless communication module, an image acquisition module, a position acquisition module and an air outlet control module (as shown in Figure 1 The control unit comprises a wireless communication module, an image acquisition module, a position acquisition module and an air outlet control module (as shown in

[0045] The air outlet control module is used to automatically adjust the temperature and wind speed near the air outlet 3 and the swing angle of the up-down swing plate 5 and the left-right swing plate 6 according to the identity information, user state, position information transmitted by the wireless communication module, image acquisition module and position acquisition module and the user's preset environmental preference, the environmental preference including temperature, wind speed, low temperature tolerance, the air outlet control module is preset with straight blowing mode and inclined blowing mode, the straight blowing mode is straight blowing of wind direction, and the inclined blowing mode is that the wind direction deviates by 10°.

[0046] The control unit is used to adjust the air outlet amount of the air conditioner indoor unit 1 near the air outlet 3 according to the user identity information, position information collected by the image sensor 2 and the pickup microphone 4, the user's preset environmental preference and whether the user is using the mobile terminal, and control the electric regulating valve on the new air outlet connected wind pipe of the temperature regulating cavity 10 to adjust the new air amount, so as to adjust the air supply temperature, control the wind speed by adjusting the rotating speed of the fan 9, and control the swing angle of the up-down swing plate 5 and the left-right swing plate 6 by the motor 11.

[0047] When the wireless communication module extracts the connection established by the user's mobile terminal and the data interaction device through a non-image collection method, the user's identity information and location are obtained, the data interaction amount between the user's mobile terminal and the data interaction device is obtained, it is judged whether the user is using the mobile terminal normally, the user state is obtained, and the data information is sent to the air outlet control module. The data interaction device is a router.

[0048] When the sound pickup microphone 4 detects that the audio equipment is used, it is judged whether the user is normally using the corresponding audio equipment, the user state is obtained, the control unit judges the position according to the preset audio equipment position map, and the data information is sent to the air outlet control module. When the sound pickup microphone 4 detects the door opening and closing sound and judges that the user is entering the room at this time, the control unit performs identity judgment. If the data interaction device detects an increase in the connection end, it is judged that the user carries a mobile terminal, and then the identity information and location information are obtained directly through the wireless communication module; if the data interaction device does not detect an increase in the connection end, it is judged that the user does not carry a mobile terminal, and then the data amount change of the mobile terminal in the entire family range is detected through the router device to assist in judging the identity information and location information; if there is no change in the data amount of the mobile terminal, the user's identity cannot be assisted to be judged, and the control unit will activate the image sensor 2 to collect and judge to confirm the user's identity and location information, and send the data information to the air outlet control module.

[0049] Specific implementation steps: first, the control unit is started, and each module is initialized, including the image sensor 2, the sound pickup microphone 4, and the wireless communication module.

[0050] User information and environmental preference configuration: Through the user's mobile terminal or the control unit, the user's identity information, environmental preferences, and air outlet 3 control mode are configured. The environmental preferences include temperature, wind speed, low temperature tolerance, etc., and the air outlet 3 mode includes direct blowing mode and inclined blowing mode.

[0051] If image recognition is enabled, the image sensor 2 starts to capture images of the room or other designated areas. The image collection module receives image data and performs person recognition based on a convolutional neural network to obtain user identity information, location information, and clothing.

[0052] When the non-image recognition method is used, the wireless communication module detects the connection state and data interaction amount of the user's mobile terminal and the router device to determine whether the user is present and active.

[0053] The sound pickup microphone 4 detects the sound of the user entering the room or the sound of the audio equipment being used to assist in determining the user's state.

[0054] If the user carries a mobile terminal, the identity information and location information are directly obtained through the wireless communication module. If the user does not carry a mobile terminal, the data volume change of the mobile terminal in the home range is detected through the routing device, and the image sensor 2 is combined to identify the person, to confirm the user identity and location.

[0055] The control unit reads the preset user environment preferences. According to the user identity, location information, dress, environment preferences, and active state, the air outlet control module automatically adjusts the temperature and air speed near the air outlet 3. The fan 9 at the bottom of the temperature adjustment cavity 10 starts to work. The input end of the fresh air outlet extends to the outside world, introducing fresh air from the outside world. In order to ensure the quality of the inhaled air, a filter screen 8 is detachably connected to the inner side wall of the input end. This filter screen 8 can effectively filter out dust, pollen and other impurities in the air, providing fresh and clean air for the room. When the fan 9 inhales air from the outside world, these air is introduced into the temperature adjustment cavity 10. In the temperature adjustment cavity 10, the mixing ratio of outdoor fresh air volume and air blown out after heat and humidity treatment of the air conditioner indoor unit 1 is adjusted, and the temperature sensor can ensure that the temperature of the gas in the temperature adjustment cavity 10 reaches the ideal set value.

[0056] Once the temperature of the air in the temperature adjustment cavity 10 is adjusted to the preset value, the gas is delivered to the corresponding air outlets 3 through the guide plates 7. The air outlet control module drives the screw rod 15 through the motor 11, drives the nut base 13 and the linkage rod 12, adjusts the swing angle of the up-down swing plate 5 and the left-right swing plate 6, realizes precise control of the air direction, and ensures that the air direction is appropriate.

[0057] The control unit continuously monitors the user state and environmental changes, such as user moving position, adjusting environment preferences, or device usage state, etc. According to the monitoring results, the control unit dynamically adjusts the air outlet 3 setting parameters, to ensure that the user is always in a comfortable air conditioning environment. The control unit regularly detects the working state of each module, such as the motor 11, temperature sensor, air speed sensor, etc. If a fault or anomaly is found, the control unit immediately alarms and prompts the user to maintain or repair.

[0058] Example 1: Image recognition of user in living room

[0059] The image sensor 2 integrated in the air conditioner indoor unit 1 starts working and captures the image of the living room area. The image acquisition module in the control unit receives the image data and identifies the person in the image based on the convolutional neural network. The identity information, clothing, and current state such as sitting and standing of the user are identified. The position acquisition module determines the specific position of the user in the living room based on the person recognition result in the image data. The control unit reads the preset user environmental preferences, including temperature, wind speed, and low-temperature tolerance. The air outlet control module automatically adjusts the temperature and wind speed of the air outlet 3 near the user's location based on the user's identity information and environmental preferences. At the same time, the swing angles of the up-down swing plate 5 and the left-right swing plate 6 are adjusted to provide the best wind direction and comfort. If the user prefers straight blowing mode, the wind direction is straight; if the user prefers oblique blowing mode, the wind direction is deviated by 10°.

[0060] Example 2: User does not use image recognition

[0061] The user's mobile terminal establishes a connection with the routing device, and the wireless communication module extracts the connection status and data interaction quantity. The control unit determines whether the user is using the mobile terminal based on the data interaction quantity. If the data interaction quantity is large, it is considered that the user is using the mobile terminal; if the data interaction quantity is small or zero, it is considered that the user may not be using or has left the room. If the user is using the mobile terminal and the location information is obtained through GPS positioning or network information positioning, the air outlet control module automatically adjusts the air outlet 3 setting parameters based on the preset environmental preferences and current environmental conditions. The control unit continuously monitors the user's state and environmental changes and dynamically adjusts as needed to ensure that the user is always in a comfortable air conditioning environment.

[0062] Example 3: When the pickup microphone 4 detects the sound of entering the door

[0063] The pickup microphone 4 can capture the sound signal of the user entering the door. After the control unit receives the sound signal, it performs identity judgment. If the user carries a mobile terminal and has established a connection with the routing device, the user's identity information and location information are directly obtained through the wireless communication module. If the user does not carry a mobile terminal, the data quantity change of the mobile terminal in the entire family range is detected through the routing device to assist in determining the user's identity and location information. If the user's identity and location information cannot be confirmed through the above-mentioned methods, the control unit activates the image sensor 2 for collection and judgment. The image sensor 2 captures the user's image and performs person recognition and position acquisition through the convolutional neural network. Based on the user's identity information and environmental preferences, the air outlet control module automatically adjusts the temperature and wind speed of the air outlet 3 near the entrance area. At the same time, the swing angles of the up-down swing plate 5 and the left-right swing plate 6 are adjusted to provide the appropriate wind direction and comfort. The control unit continuously monitors the user's state and environmental changes and dynamically adjusts as needed to ensure that the user can enjoy a comfortable air conditioning environment from entering the door to any position in the room.

[0064] Example 4: User enters the room and sits on the sofa using a mobile terminal

[0065] The pickup microphone 4 detects the sound of the user entering the room, and the control unit starts the identity judgment process. The user carries a mobile terminal, and the wireless communication module obtains the connection state and data interaction of the user's mobile terminal through the routing device, thereby obtaining the user's identity information and location information. Since the user is using the mobile terminal, the wireless communication module judges that the user is in an active state according to the data interaction. The control unit reads the preset user environmental preferences, including temperature, wind speed, cold tolerance, etc. According to the user's location information such as sitting on the sofa, as well as identity information and environmental preferences, the air outlet control module automatically adjusts the air supply temperature and speed of the air outlet 3 near the sofa. At the same time, adjust the swing angle of the up-down swing plate 5 and the left-right swing plate 6 to ensure that the wind direction is appropriate, such as the user prefers a diagonal blowing mode, then the wind direction deviates by 10°. The control unit continuously monitors the user's state and environmental changes, such as the user moving position or adjusting environmental preferences, and the control unit will automatically make corresponding adjustments.

[0066] Example 5: User enters the room without carrying a mobile terminal and uses an audio device

[0067] The pickup microphone 4 detects the sound of the user entering the room, and the control unit starts the identity judgment process. The user does not carry a mobile terminal, and the control unit detects the data volume change of the mobile terminal in the entire family range through the routing device, but no significant change is detected, so it cannot directly obtain the user's identity and location information. When the pickup microphone 4 detects the sound of the user using an audio device, such as a TV, the control unit judges that the user is in an active state. According to the preset audio device location map, the sofa orientation corresponding to the TV is obtained, and the location information is sent to the control unit. The control unit reads the location information environmental preferences, and automatically adjusts the air outlet 3 setting parameters according to the location information and state. The control unit continuously monitors the user's state and environmental changes to ensure that the user is always in a comfortable air conditioning environment.

[0068] Example 6: User enters the room with a mobile terminal but does not use any device

[0069] The pickup microphone 4 detects the sound of the user entering the room, and the control unit starts the identity judgment process. The user carries a mobile terminal, and the wireless communication module obtains the connection state and data interaction amount of the user's mobile terminal through the routing device, thereby obtaining the user's identity information and location information. Since the user does not use the mobile terminal or other devices, the wireless communication module determines that the user is in an inactive state according to the data interaction amount. The control unit reads the preset user environment preference and automatically adjusts the outlet 3 setting parameters to the preset comfortable state according to the user location information. Since the user is in an inactive state, the control unit may adopt a more conservative adjustment strategy, such as slightly adjusting the temperature and wind speed, to avoid disturbing the user. At the same time, the control unit continuously monitors the user state and environmental changes, and is ready to make rapid adjustments when the user needs it.

[0070] Embodiment 2

[0071] The method flow is shown in the accompanying Figure 2 The air conditioner outlet 3 partition flow control method includes the following steps:

[0072] Step one, image acquisition: capture the image of the covered area through the image sensor 2, and perform person recognition and identity information acquisition through the convolutional neural network.

[0073] Step two, wireless analysis: when the image acquisition mode cannot accurately identify the person and identity information, the location information, identity information of the user, and the connection state and data interaction amount between the user's mobile terminal and the routing device are obtained through the wireless communication module and the routing device.

[0074] Step three, non-image acquisition: when the wireless communication module extracts the connection established between the user's mobile terminal and the routing device through the non-image acquisition method, the user's identity information and user location are obtained, and the temperature and wind speed of the outlet 3 and the swing angle of the swing plate are automatically adjusted.

[0075] Step four, audio acquisition: when the user enters the room and triggers the audio device, identity judgment is performed. If the user carries a mobile terminal, the identity information is directly obtained; if not, the change of the mobile terminal data amount is detected through the routing device to assist in judging the identity.

[0076] Step five: collection integrity verification: if the user's identity cannot be determined through the non-image acquisition method, return to step one to activate the image sensor 2 for collection and judgment.

[0077] Step six, outlet regulation: according to the user's location information, identity information, environmental preference, and whether the user is normally using the mobile terminal or other devices, the air supply temperature and speed of the outlet 3 and the swing angle of the swing plate are automatically adjusted.

[0078] Specific implementation steps:

[0079] Step One: Image Acquisition and Person Recognition. The image sensor 2 integrated in the air conditioner indoor unit 1 captures images of the living room or other designated areas. Convolutional neural networks are used to identify people in the captured images, obtaining the user's identity information and current location.

[0080] Step Two: Wireless Analysis and User State Determination. Through the wireless communication module and routing equipment, the connection status and data interaction between the user's mobile terminal and the routing equipment are detected. According to the data interaction, it is determined whether the user is using the mobile terminal normally, thereby inferring the user's active state.

[0081] Step Three: Intelligent Control of Air Outlet. The user's temperature, wind speed, and low-temperature tolerance are read from the preset user environmental preferences. Based on the user's location information, identity information, clothing, environmental preferences, and active state, the air outlet 3's air supply temperature and speed, as well as the swing angles of the up-down swing plate 5 and left-right swing plate 6, are automatically adjusted to achieve personalized air conditioning experience.

[0082] Step Four: Control in Non-Image Acquisition Mode. When user information cannot be obtained through image acquisition, the connection information between the user's mobile terminal and the routing equipment is extracted through the wireless communication module. Based on the extracted connection information, the temperature and wind speed of the air outlet 3, as well as the swing angle of the swing plate, are automatically adjusted to maintain the comfort of the indoor environment.

[0083] Step Five: Audio Acquisition and Identity Determination. When the user enters the room and triggers the audio device, the sound signal is captured by the sound pickup microphone 4. If the user carries a mobile terminal and has established a connection with the routing equipment, the identity information is directly obtained; if not, the data volume change of the mobile terminal within the home range is detected by the routing equipment to assist in determining the user's identity.

[0084] Step Six: Acquisition Integrity Verification and Final Determination. If the user's identity and location information cannot be confirmed through the above methods, the image sensor 2 is activated for acquisition and judgment. Combining image recognition, wireless communication, and audio acquisition, the user's identity and location information are finally determined.

[0085] Suppose user A is watching TV in the living room while his phone is connected to the home's routing equipment. At this time, the air conditioner outlet 3 partitioned flow control method will follow the following steps.

[0086] Image Acquisition: The image sensor 2 captures images of the living room and identifies A's identity and location.

[0087] Wireless Analysis: The wireless communication module detects that the connection status and data interaction between A's phone and the routing equipment are large, indicating that A is using the phone.

[0088] Air outlet regulation: According to the position information, identity information of A and the preset environmental preferences, such as temperature setting of 25℃, air speed setting of medium wind, preference of oblique blowing mode, the control unit automatically adjusts the temperature and air speed of the air outlet 3 near A in the living room area, and adjusts the swing angle of the swing plate, so that the wind direction deviates from A by 10° in any direction, to avoid discomfort caused by direct blowing.

[0089] The control unit continuously monitors the state of A and environmental changes, such as A moving position or adjusting environmental preferences, and automatically adjusts accordingly to ensure that A is always in a comfortable air conditioning environment.

[0090] Example 3

[0091] Compared with Example 1, the difference is only that a carbon dioxide sensor is further included, which is located indoors for detecting the carbon dioxide concentration in the indoor air and feeding back to the control unit. The temperature regulating cavity is provided with a fresh air outlet and an indoor return air outlet, and the fan is fixed at the air outlet and located in the temperature regulating cavity. The fresh air outlet and the indoor return air outlet are both provided with electric regulating valves. The control unit is further used to adjust the outdoor fresh air volume according to the carbon dioxide concentration in the indoor air; then adjust the return air volume according to the comfort requirement of personnel, and mix the fresh air, return air and indoor air outlet air uniformly in the temperature regulating cavity to achieve the required supply air temperature.
