Description

Technical Field

[0001] This application relates to the field of air conditioning control technology, and in particular to an automated intelligent control method and controller for an air conditioner, an air conditioner, and a medium. Background Technology

[0002] Currently, air conditioners are primarily based on human-computer interaction, relying solely on intuitive user control via remote control infrared signals, voice commands, and other manual methods. However, changes in indoor lighting intensity and outdoor temperature throughout the day cause indoor temperatures to fluctuate; therefore, people's comfort requirements vary at different times and in different environments. Furthermore, different human activity levels also influence comfort levels. When these comfort requirements are not met, current air conditioners require manual intervention. Each adjustment takes time to adjust and achieve the desired comfort level, potentially requiring multiple manual adjustments. This consumes significant user effort and is neither timely nor convenient. Therefore, current air conditioning products, relying on fixed settings such as temperature, fan speed, auxiliary heating, airflow direction, and fresh air intake, lack intelligence and fail to promptly meet user comfort needs, resulting in a poor user experience. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an automated intelligent control method for an air conditioner, along with a controller, an air conditioner, and a medium. This method enables fully automatic and adaptive control of the air conditioner's operation based on user activity status and indoor environmental parameters, thereby improving the air conditioner's intelligence and enhancing the user experience.

[0004] In a first aspect, embodiments of this application provide an automated intelligent control method for an air conditioner, applied to the controller of the air conditioner, the automated control method including:

[0005] Acquire indoor environmental parameters within the monitoring range and user action status values ​​determined based on radar signals;

[0006] Determine user activity status information based on user action status values ​​and indoor environmental parameters;

[0007] When the user activity status information indicates that there is a user within the monitoring range, the air conditioner is activated, and the air conditioner is automatically controlled to adjust the temperature within the monitoring range based on the user activity status information, the signal reception of the user action status value, and the indoor environmental parameters.

[0008] When the air conditioner is turned on, it adjusts the humidity according to the indoor environmental parameters to regulate the humidity within the monitoring range.

[0009] In a second aspect, embodiments of this application provide a controller, including at least one processor and a memory for communicatively connecting to the at least one processor; the memory stores instructions executable by the at least one processor, which are executed by the at least one processor to enable the at least one processor to perform an automated intelligent control method for an air conditioner as described in any of the embodiments of the first aspect.

[0010] Thirdly, embodiments of this application provide an air conditioner, including a controller as described in the second aspect embodiment.

[0011] Fourthly, this application provides a computer-readable storage medium storing computer-executable instructions for causing a computer to perform an automated intelligent control method for an air conditioner as described in any of the embodiments of the first aspect.

[0012] This application embodiment includes the following steps: During the operation of the air conditioner, the controller first acquires indoor environmental parameters within the monitoring range and user action status values ​​determined based on radar signals; then, it determines user activity status information based on the user action status values ​​and indoor environmental parameters; subsequently, when the user activity status information indicates the presence of a user within the monitoring range, the air conditioner is activated, and the controller automatically adjusts the temperature within the monitoring range based on the user activity status information, the signal reception of the user action status values, and the indoor environmental parameters; when the air conditioner is activated, it also adjusts the humidity within the monitoring range based on the indoor environmental parameters. Thus, by automatically and intelligently adjusting the air conditioner using user activity status information and indoor environmental parameters, the controller meets the user's comfort requirements for humidity and temperature in the space. In other words, this application embodiment can automatically and adaptively control the air conditioner's operation based on user activity status and indoor environmental parameters, improving the air conditioner's intelligence and enhancing the user experience.

[0019] It should be noted that although a logical order is shown in the flowcharts in this application, in some cases, the steps shown or described may be performed in a different order than that shown in the flowcharts. In the description of this application, "several" means one or more, and "more" means two or more.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0021] This application discloses an automated intelligent control method and controller for an air conditioner, as well as an air conditioner and a computer-readable storage medium, relating to the field of air conditioning control technology. The method includes: acquiring indoor environmental parameters within a monitoring range and user action status values ​​determined based on radar signals; determining user activity status information based on the user action status values ​​and indoor environmental parameters; when the user activity status information indicates the presence of a user within the monitoring range, starting the air conditioner and automatically controlling the air conditioner to adjust the temperature within the monitoring range based on the user activity status information, the signal reception of the user action status values, and the indoor environmental parameters; and when the air conditioner is started, controlling the air conditioner to adjust the humidity within the monitoring range based on the indoor environmental parameters. This method enables fully automatic and adaptive control of the air conditioner based on user activity status and indoor environmental parameters, improving the intelligence level of the air conditioner and enhancing the user experience.

[0022] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0023] Firstly, such as Figure 1 As shown, the controller applied to the air conditioner, the automated intelligent control method of the air conditioner may include, but is not limited to, steps S110 to S140.

[0024] Step S110: Obtain indoor environmental parameters within the monitoring range and user action status values ​​determined based on radar signals.

[0025] Step S120: Determine the user activity status information based on the user action status value and indoor environmental parameters.

[0026] Step S130: When the user activity status information indicates that there is a user within the monitoring range, start the air conditioner and automatically control the air conditioner to adjust the temperature within the monitoring range based on the user activity status information, the signal reception of the user action status value, and the indoor environmental parameters.

[0027] Step S140: When the air conditioner is turned on, control the air conditioner to perform humidity adjustment according to the indoor environmental parameters, so as to adjust the humidity within the monitoring range.

[0028] Further explanation of step S110: Indoor environmental parameters include: indoor ambient temperature, light intensity level, and ambient sound information.

[0029] It is understood that the embodiments of this application collect indoor environmental parameters through the data acquisition module included in the air conditioner. Specifically, in some embodiments, the data acquisition module includes a radar monitoring module, a photosensor, a sound acquisition module, and a temperature sensor, all of which are electrically connected to the controller. The sound acquisition module may be a microphone or other similar device.

[0030] Further explanation of step S110: Specifically, the controller also uses radar signals fed back from the radar monitoring module to determine whether there are people within the monitoring range and to acquire user action status values; it uses photosensitive signals fed back from the photosensitive sensor to determine the light intensity level within the monitoring range; it uses the sound acquisition module to acquire ambient sound information; and it uses the temperature sensor to acquire the indoor ambient temperature. Specifically, the radar monitoring module, photosensitive sensor, sound acquisition module, and temperature sensor upload the acquired signals to the controller every second, enabling the controller to perform statistical analysis and acquire user action status values, ambient sound information, light intensity level, and indoor ambient temperature.

[0031] Specifically, the user action status value is used to indicate the type of user action; the user action status value includes: a first status value (specifically 01), a second status value (specifically 02), a third status value (specifically 03), and a fourth status value (specifically 04); the first status value is used to indicate that there is no user within the monitoring range and there is no action; the second status value is used to indicate that there is a user and the user is stationary; the third status value is used to indicate that there is a user and the user is slightly moving; and the fourth status value is used to indicate that there is a user and the user is moving.

[0032] Specifically, the environmental sound information includes: sound state value, volume level, and sound scene flag value. A sound state value of 1 represents a quiet state, and a sound state value of 0 represents a noisy state. It should be noted that this application only distinguishes between the quiet and noisy states; the quiet state is not absolutely quiet, but relatively quiet. The volume level is quantified into five levels from 1 to 5; and the higher the volume level, the louder the volume, and the lower the volume level, the quieter the volume. Different sound scene flag values ​​represent different sound scenes; the sound scene flag values ​​include: a first scene flag value (specifically 01), a second scene flag value (specifically 02), a third scene flag value (specifically 03), and a fourth scene flag value (specifically 04). The first scene flag value is used to represent a silent scene; the second scene flag value is used to represent a snoring scene; the third scene flag value is used to represent a talking scene; and the fourth scene flag value is used to represent other sound scenes.

[0033] Specifically, the light intensity level is quantified into five levels, from level 1 to level 5; and the higher the light intensity level, the brighter the light within the monitoring range, and the lower the light intensity level, the dimmer the light within the monitoring range.

[0034] By collecting indoor environmental parameters and user action status values ​​in step S110, the foundation is laid for subsequent fully automated intelligent control of the air conditioner.

[0035] In one embodiment, the fault definition is as follows: Under any circumstances, the data acquisition module determines that acquisition has failed and sends a default error message (00). If the data acquisition module fails to communicate with the controller for 2 consecutive minutes, it indicates that the AI ​​has failed.

[0036] Further explanation of step S120. In some embodiments, whether a user is asleep can be determined by a combination of radar signals and light intensity levels. Specifically, when the radar signal determines that there is a user indoors, and the light sensor detects that the light intensity level is less than a preset threshold after the lights are turned off or the curtains are drawn, a timer is started, and the rapid heating and cooling function is forcibly turned off.

[0037] In one embodiment, the shutdown process is performed: when the user action status value is equal to the first status value, it indicates that there is no one in the monitoring range. If no user is detected indoors for 10 minutes, the system automatically enters the low energy consumption mode, reduces the compressor speed, and runs at the medium speed in the smart energy saving mode. If no user is detected indoors for 15 minutes, the system runs at the low speed in the smart energy saving mode. If no user is detected indoors for 25 minutes, the system shuts down.

[0038] Further explanation of step S120: Determine user activity status information based on user action status values ​​and indoor environmental parameters. Specifically, determine whether there is a user within the monitoring range based on the user action status value: if the user action status value equals the first status value (specifically 01) for 60 consecutive seconds, determine that there is no user within the monitoring range; if the user action status value is greater than the first status value (specifically 01) for 10 consecutive seconds, determine that there is a user within the monitoring range. Next, if there is a user within the monitoring range, determine whether the user is asleep based on the light intensity level: if the light intensity level is less than or equal to three, determine that the lights are off or the curtains are drawn within the monitoring range, indicating that the user is asleep; if the light intensity level is greater than three, determine that there is a user within the monitoring range who is not asleep; complete the determination to obtain user activity status information. Specifically, user activity status information includes: no user within the monitoring range, user within the monitoring range; the case of user within the monitoring range can be further subdivided into: user present and not asleep, user present and asleep.

[0039] This application, through steps S110 to S140, describes a process where, during the operation of the air conditioner, the controller first acquires indoor environmental parameters within the monitoring range and user action status values ​​determined based on radar signals. Next, it determines user activity status information based on the user action status values ​​and indoor environmental parameters. Then, when the user activity status information indicates the presence of a user within the monitoring range, the air conditioner is activated. Based on the user activity status information, the signal reception of the user action status values, and the indoor environmental parameters, the controller automatically adjusts the air conditioner's temperature to regulate the temperature within the monitoring range. When the air conditioner is activated, it also adjusts the humidity based on the indoor environmental parameters to regulate the humidity within the monitoring range. Thus, by automatically and intelligently adjusting the air conditioner using user activity status information and indoor environmental parameters, the controller meets the user's comfort requirements for humidity and temperature in their living space. In other words, this application embodiment can automatically and adaptively control the air conditioner's operation based on user activity status and indoor environmental parameters, improving the air conditioner's intelligence and enhancing the user experience.

[0040] According to some embodiments of this application, indoor environmental parameters include: indoor ambient temperature, light intensity level, and ambient sound information. Further explanation of step S130: Step S130 involves automatically controlling the air conditioner to adjust the temperature based on user activity status information, signal reception of user action status values, and indoor environmental parameters, including but not limited to steps S131 to S132.

[0041] Step S131: When the user activity status information indicates that there is a user and the user is not in a sleep state, the air conditioner is subjected to the first dynamic adjustment process based on the indoor ambient temperature, the first reception of the user's action status value, and the light intensity level.

[0042] Step S132: When the user activity status information indicates that there is a user and the user is in a sleep state, determine the current user sleep scenario based on the ambient sound information and light intensity level; and perform a second dynamic adjustment process on the air conditioner based on the current air conditioner operation mode, indoor ambient temperature, preset temperature threshold information, user sleep scenario and user action status value.

[0043] Specifically, current air conditioning operating modes include: cooling mode, heating mode, dehumidification mode, etc.

[0044] Step 132 implements the intelligent sleep control mechanism. Furthermore, through steps S131 and S132, based on user activity status information, different dynamic adjustments are made according to different parameters to adaptively regulate the indoor temperature and meet the user's comfort requirements for indoor temperature.

[0045] Specifically, in step S131, the indoor environmental parameter used is the light intensity level. Step S131 will be further explained below. The following example further illustrates the specific process of the first dynamic adjustment treatment performed on the air conditioner.

[0046] Example 1: When the primary function is refrigeration:

[0047] (a) When the indoor ambient temperature T ≥ 30℃:

[0048] If the number of times a user action status value ≥2 is received is greater than 30 within a duration of 1 minute, and the user exists, the unit will be turned on immediately, enter the air supply mode, and control the air conditioner to run at the low fan speed.

[0049] If, within a 3-minute period, the number of times a user action status value ≥2 is received is greater than 120, and the user exists, then the air supply mode is maintained, and the air conditioner is controlled to switch from low fan speed to medium fan speed; otherwise, the current state is maintained.

[0050] If, within a 5-minute period, the number of times a user action status value ≥2 is received is greater than 240, and the user is present, the system switches from air supply mode to cooling mode. If the photosensitivity level is ≥3, the air conditioner is controlled at high fan speed, and the target temperature is set to 16 degrees Celsius; otherwise, the air conditioner is controlled at low fan speed, and the target temperature is set to 26 degrees Celsius. If the number of received actions is less than 240, the current state is maintained.

[0051] If the user is present and the air conditioner is on within a 7-minute period, it will be forced to switch to cooling mode. If the photosensitivity level is ≥3, the air conditioner will be controlled at high fan speed with a target temperature of 16 degrees Celsius; otherwise, it will be controlled at low fan speed with a target temperature of 26 degrees Celsius. If it is already in cooling mode, no action will be taken. This ensures that the air conditioner must enter cooling mode within 7 minutes of the user being monitored.

[0052] If the signal user action status value is continuously recorded as 0 for 7 minutes and the number of receptions is greater than 120, the device will be powered off first. Once the cooling mode is entered, the power-off process described in the above embodiment will be executed.

[0053] (b) When the indoor ambient temperature T ≥ 28℃:

[0054] If, within a 2-minute period, the number of times a user action status value ≥2 is received is greater than 60, and the user exists, the unit will be turned on immediately, entering the air supply mode and controlling the air conditioner to operate at the low fan speed.

[0055] If, within a duration of 4 minutes, the number of times a user action status value ≥2 is received is greater than 180, and the user exists, then the air supply mode is maintained, and the air conditioner is controlled to switch from low fan speed to medium fan speed; otherwise, the current state is maintained.

[0056] If, within a 6-minute period, the number of times a user action status value ≥2 is received is greater than 300, and the user is present, the system switches from air supply mode to cooling mode. If the photosensitivity level is ≥3, the air conditioner is controlled at high fan speed, and the target temperature is set to 16 degrees Celsius; otherwise, the air conditioner is controlled at low fan speed, and the target temperature is set to 26 degrees Celsius. If the number of received actions is less than 300, the current state is maintained.

[0057] If the user is present and the air conditioner is on for 8 minutes, it will be forced to switch to cooling mode. If the photosensitivity level is ≥3, the air conditioner will be controlled at high fan speed with a target temperature of 16 degrees Celsius; otherwise, it will be controlled at low fan speed with a target temperature of 26 degrees Celsius. If it is already in cooling mode, no action will be taken. This ensures that the air conditioner must enter cooling mode within 8 minutes of the user being monitored.

[0058] If the signal user action status value is continuously recorded as 0 for 8 minutes and the number of receptions is greater than 120, the device will be powered off first. Once the cooling mode is entered, the power-off process described in the embodiment will be executed.

[0059] (c) When the indoor ambient temperature T ≥ 26℃:

[0060] If, within a 3-minute period, the number of times a user action status value ≥2 is received is greater than 90, and the user exists, the unit will be turned on immediately, entering the air supply mode and controlling the air conditioner to operate at the low fan speed.

[0061] If, within a 5-minute period, the number of times a user action status value ≥2 is received is greater than 240, and the user exists, then the air supply mode is maintained, and the air conditioner is controlled to switch from low fan speed to medium fan speed; otherwise, the current state is maintained.

[0062] If, within a 7-minute period, the number of times a user action status value ≥2 is received is greater than 420, and the user is present, the system switches from air supply mode to cooling mode. If the photosensitivity level is ≥3, the air conditioner is controlled at high fan speed, and the target temperature is set to 16 degrees Celsius; otherwise, the air conditioner is controlled at low fan speed, and the target temperature is set to 26 degrees Celsius. If the number of received actions is less than 420, the current state is maintained.

[0063] If the user is present and the air conditioner is on within a 9-minute period, it will be forced to switch to cooling mode. If the photosensitivity level is ≥3, the air conditioner will be controlled at high fan speed with a target temperature of 16 degrees Celsius; otherwise, it will be controlled at low fan speed with a target temperature of 26 degrees Celsius. If it is already in cooling mode, no action will be taken. This ensures that the air conditioner must enter cooling mode within 7 minutes of the user being within the monitoring range.

[0064] If the signal user action status value is continuously recorded as 0 for 9 minutes and the number of receptions is greater than 120, the device will be powered off first. Once the cooling mode is entered, the power-off process described in the above embodiment will be executed.

[0065] Example 2:

[0066] Specifically, step 131 includes: if it is determined from the first received information regarding the indoor ambient temperature and the user's action status that it is necessary to switch to heating mode, then switch to heating mode; after switching to heating mode, perform heating control processing on the air conditioner; the heating control processing includes: if the photosensitivity level is ≥3, then control the air conditioner to high fan speed and set the target temperature to 31 degrees Celsius; otherwise, control the air conditioner to low fan speed and set the target temperature to 26 degrees Celsius. Then, perform the shutdown process mentioned in the above embodiment.

[0067] (a) When the indoor ambient temperature T≤10℃, if the number of times the user action status value ≥2 is received is greater than 240 times within a duration of 5 minutes, and the user exists, then switch to heating mode; after switching to heating mode, the above heating control process is executed.

[0068] (b) When the indoor ambient temperature T≤15℃, if the number of times the user action status value ≥2 is received is greater than 300 times within a duration of 6 minutes, and the user exists, then switch to heating mode; after switching to heating mode, the above heating control process is executed.

[0069] (c) When the indoor ambient temperature T≤24℃, if the number of times the user action status value ≥2 is received is greater than 360 times within a duration of 7 minutes, and the user exists, then switch to heating mode; after switching to heating mode, the above heating control process is executed.

[0070] It should be emphasized that the timing in Example 1 and Example 2 continues, and the relevant judgment conditions are covered step by step in accordance with (a)-(b)-(c) as time goes by.

[0071] Specifically, in step S132, determining the current user sleep scenario based on ambient sound information and light intensity level includes:

[0072] The system obtains sound status value, volume level, and sound scene flag value from ambient sound information; and determines the current user's sleep scene as a deep sleep scene when the light intensity level is less than or equal to the first light intensity level, the sound status value is equal to 1, and the volume level and sound scene flag value are less than or equal to the first discrimination threshold.

[0073] If the light intensity level is less than or equal to the second light intensity level, the sound status value is equal to 1, and the volume level and sound scene flag value are less than or equal to the second discrimination threshold, the current user's sleep scene is determined to be a moderate sleep scene; wherein, the second light intensity level is greater than the first light intensity level, and the second discrimination threshold is greater than the first discrimination threshold.

[0074] If the light intensity level is less than or equal to the third light intensity level, the sound status value is equal to 1, and the volume level and sound scene flag value are less than or equal to the third discrimination threshold, the current user's sleep scene is determined to be a light sleep scene; wherein, the third light intensity level is greater than the second light intensity level, and the third discrimination threshold is greater than the second discrimination threshold.

[0075] Specifically, the first light intensity level is 2, the second light intensity level is 3, and the third light intensity level is 4; the first discrimination threshold is 2, the second discrimination threshold is 3, and the third discrimination threshold is 4.

[0076] The following example illustrates how to determine the type of a user's sleep scenario.

[0077] Example 1: When the light intensity level is ≤2, the sound status is 1, the sound volume is ≤2, and the sound scene is ≤2, the user's sleep scene is determined to be a moderate sleep scene.

[0078] Example 2: When the light intensity level is ≤3, the sound status is 1, the sound volume is ≤3, and the sound scene is ≤3, the user's sleep scene is determined to be a moderate sleep scene.

[0079] Example 3: When the light intensity level is ≤4, the sound status is 1, the sound volume is ≤4, and the sound scene is ≤4, the user's sleep scene is determined to be a light sleep scene.

[0080] According to some embodiments of this application, the air conditioner includes: an indoor unit and an outdoor unit, the indoor unit including an indoor fan; preset temperature threshold information includes a first temperature threshold and a second temperature threshold; the second temperature threshold is less than the first temperature threshold; further describing step S132, wherein, based on the current air conditioner operating mode, indoor ambient temperature, preset temperature threshold information, user sleep scenario and user action state value, the air conditioner is subjected to a second dynamic adjustment process, including but not limited to steps S210 to S220.

[0081] Step S210: When the current air conditioner is in cooling mode, and the indoor ambient temperature is not lower than the first temperature threshold, or when the current air conditioner is in heating mode, and the indoor ambient temperature is not higher than the second temperature threshold, the indoor fan is controlled to run according to the preset fan speed, and the compressor frequency of the outdoor unit is controlled according to the frequency fuzzy control algorithm.

[0082] Step S220: When the current air conditioner is in cooling mode, if the indoor ambient temperature is less than the first temperature threshold, or when the current air conditioner is in heating mode, if the indoor ambient temperature is greater than the second temperature threshold, the cycle period is determined based on the user's sleep scenario and the indoor ambient temperature. Based on the current indoor ambient temperature and the second received information on the user's action status value within the cycle period, the indoor fan speed is adjusted to determine the target fan speed, so that the air conditioner operates at the target fan speed.

[0083] Through steps S210 to S220, the operating status of the air conditioner can be dynamically and intelligently adjusted by combining the current air conditioner operating mode, user sleep scenario, indoor ambient temperature and user action status value, thereby improving the level of intelligent control of the air conditioner and improving the user's sleep experience.

[0084] According to some embodiments of this application, step S210 is further described, wherein the compressor frequency of the outdoor unit is controlled according to the frequency fuzzy control algorithm, including but not limited to steps S211 to S214.

[0085] Step S211: Obtain the current air conditioning operating mode, actual fan speed, preset compressor coefficient, and temperature difference between indoor ambient temperature and preset temperature value.

[0086] Step S212: Determine the mode coefficient based on the air conditioner operation mode, determine the fan constant coefficient based on the actual fan speed, and determine the temperature range coefficient based on the current air conditioner operation mode and temperature difference information.

[0087] Step S213: Based on the frequency fuzzy control algorithm, perform fuzzy calculation processing according to the mode coefficient, fan constant coefficient, temperature range coefficient and preset compressor coefficient to obtain the compressor speed change.

[0088] Step S214: Add the compressor speed change to the current actual speed to determine the target compressor speed; control the compressor frequency of the outdoor unit according to the target compressor speed to enable the compressor to operate in variable frequency mode.

[0089] Specifically, the same fuzzy inference system is used regardless of whether the current air conditioner is in cooling or heating mode.

[0090] Specifically, step S212 includes: when the current air conditioning operating mode is heating mode, determining the mode coefficient as the preset heating coefficient CHEAT; when the current air conditioning operating mode is cooling mode, determining the mode coefficient as the preset cooling coefficient CCOOL. The corresponding fan constant coefficient is looked up in the second preset mapping table based on the actual fan speed. A target temperature zone diagram is determined according to the current air conditioning operating mode: if it is cooling mode, then... Figure 2 The diagram shows the first temperature zone; if it is in heating mode, then select as shown below. Figure 3 The diagram shows the second temperature zone. Based on the temperature difference between the indoor ambient temperature and the preset temperature value, the target temperature zone is determined in the target temperature zone diagram. The corresponding temperature interval coefficient ΔD value is then determined by consulting the first preset mapping table based on the target temperature zone.

[0091] Specifically, step S213: Input the mode coefficient, ΔD value, fan constant coefficient, and preset compressor coefficient into the fuzzy inference system, and obtain the compressor speed change through the fuzzy operation processing of the fuzzy inference system.

[0092] Steps S211 to S214 establish a mechanism for controlling the compressor frequency based on a frequency fuzzy control algorithm. This intelligently controls the air conditioner compressor frequency based on the indoor ambient temperature, ensuring the inverter air conditioner effectively regulates the indoor temperature and meets the comfort requirements of indoor users.

[0093] Step S220: When the current air conditioner is in cooling mode, if the indoor ambient temperature is less than the first temperature threshold, or when the current air conditioner is in heating mode, if the indoor ambient temperature is greater than the second temperature threshold, the cycle period is determined based on the user's sleep scenario and the indoor ambient temperature. Based on the current indoor ambient temperature and the second received information on the user's action status value within the cycle period, the indoor fan speed is adjusted to determine the target fan speed, so that the air conditioner operates at the target fan speed.

[0094] Specifically, the first temperature threshold is 30 degrees Celsius; the second temperature threshold is 10 degrees Celsius.

[0095] Specifically, the target fan speed is determined through an internal fan speed adjustment process. This process includes: determining if the receiving conditions meet the startup criteria; if so, performing a first speed adjustment; this first adjustment involves controlling the fan speed according to the AI ​​automatic wind control mode to determine the target fan speed; if not, performing a second speed adjustment; this second adjustment involves subtracting one speed from the current fan speed to obtain the target fan speed. If the target fan speed is the lowest speed or lower than the current lowest speed, the current fan speed is set as the target fan speed and remains unchanged. This internal fan speed adjustment process is repeated after each cycle.

[0096] It should be noted that this application quantifies the fan speed settings in the air conditioner into 10 levels, with the motor controlling uniform speed adjustment. The system is designed to automatically and uniformly control the fan speed within a maximum acceleration / deceleration range of 600 rpm / min, achieving smooth control. The fan speed settings are denoted as FI0 to FI9; different fan speed settings indicate different fan rotation speeds; a higher fan speed setting indicates a higher fan rotation speed, and a lower fan speed setting indicates a lower fan rotation speed.

[0097] The AI ​​automatic fan control mode of this application embodiment is further described below. The AI ​​automatic fan control mode is only activated when automatic fan is set or when entering intelligent sleep mode. Specifically, the automatic fan can only be selected during cooling and heating modes; it cannot be selected during dehumidification and ventilation modes.

[0098] Specifically, in cooling mode, based on the temperature range of the indoor ambient temperature, the system automatically locates and determines the target fan speed from the first preset fan speed reference table, and automatically controls the fan to operate at the speed indicated by the target fan speed, thus achieving automatic fan operation during cooling. The first preset fan speed reference table is shown in Table 1 below.

[0101] Specifically, in heating mode, based on the temperature range of the indoor ambient temperature, the system automatically locates and determines the target fan speed from the second preset fan speed reference table, and automatically controls the fan to operate at the speed indicated by the target fan speed, thus achieving automatic fan operation during heating. The second preset fan speed reference table is shown in Table 2 below.

[0104]

[0105] It should be noted that, in principle, the target fan speed corresponding to the target fan speed setting is used as the fan indicated speed. However, due to the limitation of the anti-cold air protection control, if the upper limit of the anti-cold air protection is lower than the target fan speed, the upper limit of the anti-cold air protection will be used as the fan indicated speed.

[0106] When the air conditioner is currently operating in cooling mode, there may be scenarios where the temperature within the monitoring range decreases or increases. Specifically, for example... Figure 2 As shown, a "zone diagram" illustrates the controller's start / stop rules under different first temperature differences (the first temperature difference being the difference between room temperature and the target set temperature). From... Figure 2 The text indicates that the air conditioner will shut down (OFF) when the first temperature difference is -1.5℃, and provides a division of operating states under different first temperature differences. The shutdown point temperature (OFF temperature) refers to the critical temperature threshold at which the air conditioner automatically stops operating after reaching the set temperature; it is a key parameter in the air conditioning control system used to determine when to shut down the compressor or the entire unit. Specifically, Figure 2 In the diagram, the forward-direction region represents the temperature decrease during refrigeration; the reverse-direction region represents the temperature increase during refrigeration; and the thermostat recovery region represents the conditions under which the controller recovers from the OFF state. When the first temperature difference is on the dividing line, it is included in the previous temperature region.

[0107] When the air conditioner is currently operating in heating mode, there may be scenarios where the temperature within the monitoring range decreases or increases. Specifically, for example... Figure 3 As shown, a "zone diagram" illustrates the controller's start / stop rules under different second temperature differences (the second temperature difference being the target set temperature minus the room temperature). From... Figure 3 The text indicates that the air conditioner will shut down (OFF) when the second temperature difference is -1.5℃, and provides a division of operating states under different second temperature differences. The shutdown point temperature (OFF temperature) refers to the critical temperature threshold at which the air conditioner automatically stops operating after reaching the set temperature; it is a key parameter in the air conditioning control system used to determine when to shut down the compressor or the entire unit. Specifically, Figure 3 In the diagram, the forward-facing region represents the temperature rise during heating; the reverse-facing region represents the temperature drop during heating; and the thermostat recovery region represents the conditions under which the controller recovers from the OFF state. When the second temperature difference is on the dividing line, it is included in the previous temperature region.

[0111] It is determined that the range of wind speed gear is: FI3 to FI6; that is, FI3 is the minimum wind speed gear and FI6 is the maximum wind speed gear, and the cycle period is 20min. The duration of radar signals is obtained by timing, and judgment is made according to the reception condition of user action state values within the cycle period: when within the cycle period, the number of received user action state values ≥ 3 is greater than 120 times, it is judged that the start condition is satisfied, and the first gear adjustment process is performed to determine the target wind speed gear; otherwise, when the start condition is not satisfied, the above-mentioned second gear adjustment process is performed. Thus, the target wind speed gear is determined, so that the air conditioner operates at the target wind speed gear. In this way, in a light sleep scenario where the indoor ambient temperature is relatively high or relatively low, gear reduction will not occur easily, thereby ensuring temperature comfort.

[0112] (2) For the scenario of temperature drop during cooling, when the indoor ambient temperature satisfies 28℃ > T ≥ 26℃, or for the scenario of temperature rise during heating, when the indoor ambient temperature satisfies 15℃ < T ≤ 23℃, the following processing is performed:

Thus, the target wind speed gear is determined, so that the air conditioner operates at the target wind speed gear. In a light sleep scenario where the indoor ambient temperature is relatively high, gear reduction will not occur easily, thereby ensuring temperature comfort.

[0114] (3) For the scenario of temperature drop during cooling, when the indoor ambient temperature satisfies 26℃ > T ≥ 24℃, or for the scenario of temperature rise during heating, when the indoor ambient temperature satisfies 23℃ < T ≤ 26℃, the following processing is performed:

Thus, the target wind speed gear is determined, so that the air conditioner operates at the target wind speed gear.

[0125] (4) For the scenario of temperature drop during cooling, when indoor ambient temperature T < 24°C, it is considered that the set temperature may be relatively low and the required temperature is relatively low, after continuous operation in this temperature interval for 5 min, determine that the range of wind speed gears is from FI1 to FI3, and the circulation period is 9 min; or for the scenario of temperature rise during heating, when indoor ambient temperature T > 26°C, it is considered that the set temperature may be relatively high and the required temperature is relatively high, after continuous operation in this temperature interval for 5 min, determine that the range of wind speed gears is from FI1 to FI3, and the circulation period is 14 min, then the following processing is performed:

[0163] Through step S220, under the condition that the current air conditioner operation mode is heating mode or cooling mode, the intelligent control of the sleep mode of the air conditioner is implemented according to a preset control algorithm in combination with the sleep scenario, the monitored indoor ambient temperature and the user action status value in the sleep state, so as to automatically adjust the temperature, help reduce energy consumption, and create a high-quality and comfortable sleep environment.

[0164] According to some embodiments of the present application, step S140 is further described, step S140: controlling the air conditioner to perform humidity adjustment processing according to indoor environmental parameters to adjust the humidity within the monitoring range, including but not limited to steps 141 to 143.

[0165] Step 141: acquiring indoor ambient humidity, a first humidity threshold, and a second humidity threshold greater than the first humidity threshold from the indoor environmental parameters.

[0166] Step 142: When the indoor humidity is less than the first humidity threshold, control the air conditioner to adjust the humidity according to the first humidity working mode in order to adjust the humidity within the monitoring range.

[0167] Step 143: When the indoor humidity is greater than the second humidity threshold, control the air conditioner to adjust the humidity according to the second humidity working mode in order to adjust the humidity within the monitoring range.

[0168] Specifically, the first humidity threshold is 40%, and the second humidity threshold is 60%. Indoor ambient humidity refers to air humidity.

[0169] It should be noted that when the air conditioner is dehumidifying, there may be scenarios where the temperature within the monitoring range decreases or increases. Specifically, for example... Figure 4 As shown, a "zone diagram" illustrates the controller's start / stop rules under different third temperature differences (the third temperature difference being the difference between room temperature and the target set temperature). From... Figure 4 The text indicates that the air conditioner will shut down (OFF) when the third temperature difference is -1.5℃, and provides a breakdown of operating states under different third temperature differences. The shutdown point temperature (OFF temperature) refers to the critical temperature threshold at which the air conditioner automatically stops operating after reaching the set temperature. Specifically, Figure 3 In the diagram, the forward-direction zone represents the temperature decrease during dehumidification; the reverse-direction zone represents the temperature increase during dehumidification; and the thermostat recovery zone represents the conditions under which the controller recovers from the OFF state. When the third temperature difference is on the dividing line, it is included in the previous temperature zone.

[0170] Specifically, the air conditioner includes a UVC module. UVC (Ultraviolet C) refers to UVC deep ultraviolet light sterilization technology, which uses short-wave ultraviolet light with wavelengths between 200-280 nanometers (nm) (mainly 253.7-265nm) to kill bacteria, viruses and fungi in the air.

[0171] Specifically, when the indoor humidity is less than 40%, step 142, controlling the air conditioner to adjust humidity according to the first humidity operating mode, includes: turning on the UVC module each time the unit is turned on and the indoor fan is running continuously at a speed greater than 300 RPM; turning off the UVC module after a cumulative 2 hours of operation; turning off the UVC module at the same time as the unit is turned off; if the UVC module is detected to be turned off and then on again during the UVC module's operation, the UVC operation time is reset to zero and restarted. Additionally, as long as the unit is on, the cooling and heating operation is within the direction of operation (e.g., ...). Figure 2 , Figure 3As shown, the fresh air fan operates for 8 minutes every hour in automatic fan speed adjustment mode; when not in the cooling / heating operating direction range, the fresh air fan operates for 4 minutes every hour. Simultaneously, when the user is asleep, the temperature is automatically controlled by the intelligent sleep control mechanism in step 132.

[0172] Specifically, when the indoor humidity is greater than 60%, step 143, controlling the air conditioner to adjust humidity according to the second humidity operating mode, includes: turning on the UVC module each time the unit is turned on and the indoor fan is running continuously at a speed greater than 300 RPM; turning off the UVC module after a cumulative 2 hours of operation; turning off the UVC module simultaneously with the unit. If the UVC module is detected turning off and then on again during its operation, the UVC operation time is reset to zero. Additionally, as long as the unit is on, the cooling / heating operation is within the direction of operation (e.g., ...). Figure 2 , Figure 3 As shown, the fresh air fan operates for 8 minutes every hour in automatic fan speed adjustment mode; when not in the forward direction of cooling or heating operation, the fresh air fan operates for 4 minutes every hour. Simultaneously, when the user is asleep, the temperature is automatically controlled via the intelligent sleep control mechanism in step 132. Furthermore, if in cooling mode the indoor humidity is ≥70% and remains within the forward direction range for 30 minutes, the compressor switches to dehumidification control. After switching to dehumidification, if the humidity remains within the reverse direction range for 10 minutes, cooling control resumes. This switching is performed only once per startup.

[0173] Through steps S141 to S143, the air conditioner can be intelligently adjusted based on the indoor ambient humidity to meet the comfort requirements of users within the monitoring range.

[0174] According to some embodiments of this application, the automated intelligent control method for air conditioners also includes, but is not limited to, steps S310 to S340.

[0175] Step S310: When the air conditioner is in cooling mode, during the process of determining the target fan speed by adjusting the indoor fan speed, the heat exchanger temperature information is obtained.

[0176] Step S320: Determine the condensation state and freezing state based on the heat exchanger temperature information.

[0177] Step S330: Determine the upper limit speed of the first compressor based on the condensation state, perform indoor anti-drip control treatment on the air conditioner, and control the operation of the air conditioner based on the upper limit speed of the first compressor.

[0178] Step S340: Determine the upper limit speed of the second compressor based on the frozen state, perform indoor anti-freeze control on the air conditioner, and control the operation of the air conditioner according to the upper limit speed of the second compressor.

[0179] Specifically, in step S310, the heat exchanger temperature information includes: the temperature of the first heat exchanger and the temperature of the second heat exchanger.

[0180] Specifically, the condensation state includes four states: recovery, increased ability, maintenance, and decreased ability. The frozen state includes four states: recovery, increased ability, maintenance, decreased ability, and stop.

[0181] Specifically, step S320 includes: determining the condensation state based on the temperature of the first heat exchanger of the indoor unit; and determining the freezing state based on the temperature of the second heat exchanger of the indoor unit.

[0182] Specifically, determining the condensation state based on the temperature of the first heat exchanger of the indoor unit includes: First, calculating the first judgment threshold: DCTUYU = ATUYU + BTUYU * TR; where TR is the current indoor ambient temperature value; ATUYU is a preset first constant coefficient, and BTUYU is a preset second constant coefficient. Next, determining the second judgment threshold as: DCTUYU + TUYUDC1; TUYUDC1 is a positive temperature difference, and the second judgment threshold is greater than the first judgment threshold. Then, determining the third judgment threshold as: DCTUYU + TUYUDC2; TUYUDC2 is a positive temperature difference, and the third judgment threshold is greater than the second judgment threshold. Then, when the temperature of the first heat exchanger is less than the first judgment threshold, the condensation state is determined to be: reduced capacity; when the temperature of the first heat exchanger is greater than or equal to the first judgment threshold and less than the second judgment threshold, the condensation state is determined to be: maintained; when the temperature of the first heat exchanger is greater than or equal to the second judgment threshold and less than the third judgment threshold, the condensation state is determined to be: increased capacity; when the temperature of the first heat exchanger is greater than or equal to the third judgment threshold, the condensation state is determined to be: restored.

[0183] Specifically, determining the freezing state based on the temperature of the second heat exchanger of the indoor unit includes: acquiring a fourth judgment threshold DT00, a fifth judgment threshold DT01, a sixth judgment threshold DT02, and a seventh judgment threshold DT03; when the temperature of the second heat exchanger is less than the fourth judgment threshold DT00, the freezing state is determined to be recovery; when the temperature of the second heat exchanger is greater than or equal to the fourth judgment threshold DT00 and less than the fifth judgment threshold DT01, the freezing state is determined to be enhanced capability; when the temperature of the second heat exchanger is greater than or equal to the fifth judgment threshold DT01 and less than the sixth judgment threshold DT02, the freezing state is determined to be maintenance; when the temperature of the second heat exchanger is greater than or equal to the sixth judgment threshold DT02 and less than the seventh judgment threshold DT03, the freezing state is determined to be enhanced capability; and when the temperature of the second heat exchanger is greater than or equal to the seventh judgment threshold DT03, the freezing state is determined to be recovery.

[0184] Specifically, in step S330, the process of determining the upper limit speed of the first compressor includes: looking up the upper limit speed of the first compressor in a first preset speed table based on the condensation state. The first preset speed table is shown in Table 3.

[0185] In Table 3, HZITUYU is the preset compressor speed change when increasing / decreasing the indoor anti-drip control capacity. It should be noted that when the condensation state is reduced capacity, the speed = current actual speed - HZITUYU, but this speed is not less than the compressor's lower limit control speed HZMIN.

[0186] Table 3

[0187] recover 120r / s Increase capabilities Current actual revolutions + HZITUYU Keep Current actual revolutions Reduce capabilities Current actual revolutions - HZITUYU

[0188] Step S330 prevents condensation and dripping of water from the indoor heat exchanger during cooling or dehumidification operations, thus achieving drip prevention.

[0189] Specifically, in step S340, the process of determining the upper limit speed of the second compressor includes: looking up the second preset speed table according to the freeze state to determine the upper limit speed of the second compressor. The second preset speed table is shown in Table 4. In Table 4, HZIFRO is the change in compressor speed when increasing or decreasing capacity in the indoor freeze protection control. It should be noted that when the freeze state is a capacity reduction, the speed = the current actual speed - HZIFRO, but this speed is not less than the lower limit control speed of the compressor HZMIN.

[0190] In Table 4, when the freeze state is "stopped," the speed is determined according to the preset operation. The preset operation is as follows: when the indoor fan speed is FI1, the temperature of the heat exchanger continues to be monitored; the compressor stops working, the counter CFRSTOP+1 is incremented, and the upper limit speed of the second compressor remains unchanged from the upper limit speed before the compressor stopped. After the compressor restart control is completed, when the indoor freeze state is any other than "stopped," the compressor restarts, and the upper limit speed of the second compressor is determined with reference to Table 4 to control the compressor.

[0191] Table 4

[0192]

[0193] During cooling or dehumidification, when the temperature of the indoor heat exchanger drops to the freezing temperature of the condensate, the condensate will freeze on the heat exchanger. To prevent freezing, this embodiment reduces the capacity supply in step S340 to prevent the condensate in the air circuit from freezing during cooling or dehumidification.

[0194] According to some embodiments of this application, the air conditioner also includes a fresh air guide damper and a fresh air motor, and the automated intelligent control method of the air conditioner also includes, but is not limited to, steps S410 to S430.

[0195] Step S410: In response to the fresh air start signal, open the fresh air guide damper to the initial position.

[0196] Step S420: Obtain the continuously operating internal fan speed and the carbon dioxide concentration within the monitoring range. When the internal fan speed is greater than the speed threshold, start the fresh air motor.

[0197] Step S430: When the fresh air motor is in automatic wind speed adjustment mode, the wind speed of the fresh air motor is switched according to the carbon dioxide concentration.

[0198] Specifically, the speed threshold is 300 RPM.

[0199] Specifically, the fresh air function has four fan speed modes: low, medium, high, and automatic fan speed adjustment. The low fan speed is a fixed 1000 rpm, the medium fan speed is a fixed 1300 rpm, and the high fan speed is a fixed 1600 rpm. The automatic fan speed adjustment mode automatically adjusts the fan speed according to the carbon dioxide concentration, switching between low, medium, and high fan speeds, and must ensure a minimum running time of 3 minutes and 30 seconds.

[0200] In one embodiment, when a fresh air function shutdown signal is received, the fresh air motor is first shut off, and then the fresh air duct is closed.

[0201] The fresh air function is implemented through steps S410 to S430, further improving the user experience.

[0202] In one embodiment, during deep sleep or moderate sleep, the fresh air motor is turned on at a low speed (1000 rpm) for 5 minutes every 2 hours.

[0203] In one embodiment, after entering a sleep mode, the wind deflector is opened to a gentle breeze to prevent direct airflow in cooling mode, and to a carpet breeze position in heating mode.

[0204] In summary, the controller in this embodiment shuts down when no one is present, and activates a managed service when someone is present, performing AI-based dynamic temperature adjustment based on the person's activity status and indoor environmental parameters, thereby achieving fully automatic intelligent managed control of the air conditioner.
