Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning technology, and more specifically, to a fuzzy control method for intelligent air supply and an air conditioner. Background Technology
[0002] Currently, some air conditioners on the market have intelligent air delivery (airflow follows people or avoids people) functions. This function often uses radar detection, which identifies the current location of people through a radar module. The radar module transmits the location to the air conditioner controller, which then controls the angle of the air sweeping blades to achieve intelligent air delivery (airflow follows people or avoids people).
[0003] However, in actual use, the user experience deteriorates when there are multiple users. The main reason is that when there are other easily swaying objects around the air conditioner (such as curtains, plants, or leaves), the air conditioner may sway during airflow, causing the radar to misidentify them as users. This disrupts the intelligent airflow, affecting the user experience. Currently, solutions often involve adding infrared human detection to filter people / objects, or using high-precision radar modules that can identify object shapes to ensure a high recognition rate for people. However, both methods significantly increase costs. Summary of the Invention
[0004] Therefore, embodiments of the present invention provide a fuzzy control method and an air conditioner for intelligent air supply, which improves intelligent perception and user experience.
[0005] To address the aforementioned problems, this invention provides a fuzzy control method for intelligent air supply, comprising: when the air conditioner receives an intelligent air supply command sent by a control module, acquiring the first operating state of the current air conditioner; acquiring the location information of the target object through a radar module; and controlling the operating state of the air conditioner according to the intelligent air supply command, the location information, and the first operating state; wherein, the intelligent air supply command includes wind avoidance and wind following.
[0006] Compared with existing technologies, the technical effects achieved by adopting this solution are as follows: By setting the initial operating state of the air conditioner upon receiving a smart air supply command, the current state of the air conditioner can be combined with subsequent commands, making the execution of commands more closely aligned with the current state of the air conditioner. Simultaneously, a radar module is set up to acquire the location information of the target object, enabling rapid determination of the target object's location. This provides a better and more accurate basis for judging the smart air supply command, allowing it to better serve the user, thereby improving intelligent perception and enhancing the user experience.
[0007] In one embodiment of the present invention, after obtaining the current operating status of the air conditioner, the process includes: controlling the air conditioner's air guide vanes to move to a first position and controlling the air supply level to be adjusted to a low level; wherein, the first position is the maximum sweeping angle of the left and right air guide vanes of the air conditioner.
[0008] Compared with existing technologies, the technical effect achieved by adopting this technical solution is as follows: By setting the air conditioner's air guide blades to the maximum sweep angle and adjusting the air supply level to a low setting, it prevents easily swaying objects around the air conditioner from swaying due to the air conditioner's airflow, which could affect the subsequent radar module's detection, cause misjudgments, and negatively impact the user experience, thus failing to demonstrate the effect of intelligent air supply.
[0009] In one embodiment of the present invention, obtaining the location information of the target object through the radar module includes: detecting whether the target object is a moving object; if the target object is not a moving object, controlling the air conditioner to operate in a first operating state; if the target object is a moving object, detecting the number of currently moving objects; when the number is 1, controlling the air conditioner to execute a first operating mode; when the number is greater than 1, controlling the air conditioner to execute a second operating mode.
[0010] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting up a radar module to detect whether the target object is a moving object, and by controlling the air conditioner differently based on the number of moving objects, the air conditioner can perform different actions under different numbers of moving objects, making the air conditioner more intelligent in its recognition, that is, more comprehensive in its intelligent perception, and thus providing a better user experience under the command of intelligent air delivery.
[0011] In one embodiment of the present invention, the first operating state includes the air conditioner's air supply level being set to the first wind speed. When the quantity is 1, controlling the air conditioner to execute the first operating mode further includes: when the intelligent air supply command is "wind follows people", controlling the air conditioner's air supply level to be adjusted to the first wind speed; obtaining the first angle information of the current target object, and controlling the air conditioner's guide vane angle to be kept within a first range, and the first range includes the first angle information; wherein, the first angle information is the angle value between the line connecting the target object and the air conditioner and the plane of the air conditioner.
[0012] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: when the number of moving objects is one and the intelligent air supply command is "wind follows the person", the radar obtains the first angle information of the current target object, and at the same time, the angle of the air guide blades is set to be kept within a first range, and the first range includes the first angle information. In this way, the air sweeping range of the air conditioner can be controlled to be controlled close to the target object, that is, to ensure that the air supply can follow the target object and achieve the purpose of "wind follows the person".
[0013] In one embodiment of the present invention, the first operating state includes the air conditioner's air supply level being set to the first fan speed. When the quantity is 1, controlling the air conditioner to execute the first operating mode further includes: when the intelligent air supply command is "wind avoids people," controlling the air conditioner's air supply level to be adjusted to the first fan speed; and recording the maximum angle of movement of the air conditioner's air guide vanes as θ. 止 The minimum angle is denoted as θ. 起 ; Obtain the second angle information of the target object, and compare the second angle information with θ 止 The absolute value of the difference is denoted as |△θ|, and a fixed angular error value of △D is defined, where △D is greater than 0. If |△θ| ≥ △D, then the angle of the air guide vanes of the air conditioner is controlled as θ. 止 If |△θ| < △D, then the angle of the air guide vanes controlling the air conditioner is θ. 起 .
[0014] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting the movement quantity to one and the command to avoid people, the second angle information of the target object is obtained and compared with the maximum sweep angle of the guide vanes to obtain the difference. This difference is then compared with the angle error to obtain the comparison result. If the difference is greater than or equal to the angle error, it means that the current target object is not at the maximum sweep angle, and air can be delivered at this point to achieve the effect of avoiding people. Otherwise, air is delivered at the minimum angle. By obtaining the angle information of the target object and controlling the angle of the guide vanes, the effect of intelligent air delivery is achieved. This not only simplifies the control method and eliminates the need for high-precision infrared radar to achieve the current effect, thus reducing costs, but also achieves a good intelligent perception effect, resulting in a better user experience.
[0015] In one embodiment of the present invention, when the quantity is greater than 1, the air conditioner is controlled to execute a second operating mode, including: denoting the maximum angle of movement of the air conditioner's air guide vanes as θ. 止 Define a fixed angular error value as ΔD, where ΔD is greater than 0; record the third angle information of all current target objects sequentially, denoted as Dn, where n is a natural number greater than 0; compare θ respectively. 止 The difference between the value of ΔDn and the value of ΔD is obtained. The absolute value of the difference is recorded as |ΔDn|. The values of |ΔDn| and ΔD are compared. If |ΔDn| is greater than ΔD, the air conditioner is controlled to perform the first action. If |ΔDn| is less than or equal to ΔD, the air conditioner is controlled to perform the calibration action.
[0016] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting the angle information of all target objects to be acquired when the number of moving objects is greater than 1, and comparing it with the maximum angle value of the air conditioner's air guide vanes, the difference is obtained. By comparing the absolute value of the difference with the angle error, it is determined whether there is a swaying object at the current maximum angle. When the difference is less than or equal to the angle error, it indicates that there may be a misjudgment at the current maximum angle, and further judgment is required. This makes the air conditioner's judgment of swaying objects more accurate. By acquiring the angle and controlling the angle of the air guide vanes, it is easier to identify and judge target objects, improving the level of intelligent perception and thus ensuring the user experience.
[0017] In one embodiment of the present invention, if |△Dn|≤△D, then the air conditioner is controlled to perform a calibration action, including: defining θ 中轴 The maximum angle θ for the movement of the air conditioner's air guide vanes 止 and minimum angle θ 起 The angle between these values forms an intermediate value; the angle of the air conditioner's guide vanes is controlled by θ. 止 Change to θ 中轴 Detect the fourth angle information of all current target objects, denoted as Dn~, where n is a natural number greater than 0; compare θ respectively. 止 The difference between ΔDn and ΔD is calculated, and the absolute value of the difference is denoted as |ΔDn~|. The magnitudes of |ΔDn~| and ΔD are then compared. If |ΔDn~| is greater than ΔD, the target object is determined to be a non-user, and the fourth angle information is θ. 止 The target object ±△D does not record its location information. After clearing the location information of the current target object, the air conditioner is controlled to perform the first action. If there exists |△Dn~|≤△D, then the target object is determined to be the user. After clearing the location information of the current target object, the air conditioner is controlled to perform the first action.
[0018] Compared with existing technologies, the technical effects achieved by adopting this technical solution are: by setting θ 中轴 The current angle information of all target objects is compared again to obtain the corresponding difference value, which is then compared with the angle error value. If both are greater than the angle error, it means that the current object will not sway when not blown by the wind, indicating that the current object is a swaying object. Otherwise, it is a user. By changing the angle of the air guide blades and measuring again, misjudgment caused by the swaying of swaying objects due to wind is avoided. There is no need to use infrared radar to identify whether it is a user, which not only reduces costs but also makes the judgment simpler, improves the intelligent perception of the air conditioner, and thus makes the user experience better when using intelligent air supply commands.
[0019] In one embodiment of the present invention, the first operating state includes setting the air conditioner's fan speed to the first fan speed, and controlling the air conditioner to perform a first action, including: when the intelligent fan speed command is "follow the person," controlling the air conditioner's fan speed to adjust to the first fan speed; acquiring the fifth angle information of all current target objects, denoted as Gn, where n is a natural number greater than 0; and comparing Gn with θ respectively. 中轴 The size; if Gn is less than or equal to θ 中轴 The angle of the air guide vanes of the air conditioner is controlled by θ. 中轴 -θ 起 -θ 中轴 Loop; if Gn is greater than θ 中轴 The angle of the air guide vanes of the air conditioner is controlled by θ. 中轴 -θ 止 -θ 中轴 In the cycle, otherwise, the angle of the air conditioner's guide vanes is controlled to change by θ. 起 -θ 中轴 -θ 止 -θ 中轴 -θ 起 cycle.
[0020] Compared with existing technologies, the technical effects achieved by this solution are as follows: by setting up multiple moving objects and using the command "wind follows person", the angle information of all target objects can be obtained and compared with θ. 中轴 By comparing the angle values, it is possible to quickly determine whether the current target object is nearby, and then quickly determine the cycle mode of the current air guide vane sweeping angle. By comparing the air guide angle and the angle value of the target object, the location of the target object and the intelligent air supply sweeping mode as needed are realized more quickly. It is no longer necessary to rely on high-precision infrared radar, which reduces costs, improves the intelligent perception of the air conditioner, and thus ensures the user experience when using intelligent air supply commands.
[0021] In one embodiment of the present invention, the first operating state includes setting the air conditioner to the first fan speed and controlling the air conditioner to perform a first action, and also includes: when the intelligent air supply command is "wind avoids people", acquiring the sixth angle information of all current target objects, denoted as Gn~, and comparing Gn~ with θ 止 Calculate the difference, and take the absolute value of the difference, denoted as |△θn|. If |△θn| is greater than △D, then adjust the air conditioner's fan speed to the first setting, and maintain the air conditioner's guide vane angle at θ. 止 Otherwise, adjust the air conditioner to keep the fan speed low.
[0022] Compared with existing technologies, the technical effects achieved by this solution are as follows: When the air conditioner needs to execute a wind avoidance command, it controls and acquires the angle information of all target objects, and calculates the difference between this information and the maximum sweep angle value of the air conditioner's guide vanes. The difference is then compared with the angle error value to quickly determine whether the current position of all target objects will be blown by the wind. If both values are greater than the angle error, it means that none of the target objects are in the direction of the maximum sweep angle, and the airflow in this direction can be maintained to achieve the wind avoidance effect. Conversely, if the difference is less than the angle error, it means that the distribution of moving objects is relatively wide and cannot be avoided, so a low fan speed is activated to ensure the user's wind avoidance experience.
[0023] The present invention also provides an air conditioner, comprising: an acquisition module, which is used to acquire the first operating state of the air conditioner when the air conditioner receives an intelligent air supply command sent by the control module, and to acquire the location information of the target object through a radar module; and a control module, which is used to control the operating state of the air conditioner according to the intelligent air supply command, the location information and the first operating state.
[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by acquiring the current first operating state of the air conditioner, the intelligent air supply command, and the location information of the target object through the acquisition module, the subsequent control module can quickly determine the specific control method of the current air conditioner's intelligent air supply command based on the data obtained by the acquisition module, thereby improving the intelligent perception level of the air conditioner.
[0025] By adopting the technical solution of the present invention, the following technical effects can be achieved:
[0026] (1) By setting up a radar module to detect whether the target object is a moving object, different controls are executed on the air conditioner based on the number of moving objects, so that the air conditioner has different execution modes under different numbers of moving objects, making the air conditioner more intelligent in its identification, that is, more comprehensive in its intelligent perception, and thus making the user experience better under the intelligent air supply command.
[0027] (2) By setting the angle information of all target objects when the number of moving objects is greater than 1, and comparing it with the maximum angle value of the air conditioner guide vane, the difference is obtained. By comparing the absolute value of the difference with the angle error, it is determined whether there is an easily swaying object at the current maximum angle. When the difference is less than or equal to the angle error, it indicates that there may be a misjudgment at the current maximum angle, and further judgment is required. This makes the current air conditioner's judgment of easily swaying objects more accurate. By obtaining the angle and controlling the angle of the guide vane, it is easier to identify and judge the target object, which improves the degree of intelligent perception and thus ensures the user experience.

[0033] To make the above-mentioned objectives, features, and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] [First Embodiment]
[0035] See Figure 1 This invention provides a fuzzy control method for intelligent air supply, comprising:
[0036] Step S100: When the air conditioner receives the intelligent air supply command sent by the control module, it obtains the current first operating status of the air conditioner;
[0037] Step S200: Obtain the location information of the target object through the radar module;
[0038] Step S300: Control the operating status of the air conditioner according to the intelligent air supply command, location information and the first operating status;
[0039] Among them, the intelligent air delivery command includes wind avoidance and wind following.
[0040] Specifically, such as Figure 2 As shown by the yellow line, the left and right air guiding angle range of the air conditioner's air guide vanes is defined as θ. 起 ~θ 止 , where θ 起 >0, θ 止 >θ 起 θ 起θ is the starting position angle for the sweeping of the left and right air guide vanes of the air conditioner. 止 This allows the left and right guide vanes to move to their maximum angle during sweeping. For example... Figure 2 As shown by the purple line, the angular range for the radar module to identify moving objects is defined as D. 起 ~D 止 D 起 <θ 起 D 止 >θ 止 The air guide angle is controlled by the main controller, which determines the position and angle of the left and right air sweeping blades of the air conditioner. The air conditioner controls the air delivery angle by controlling the position of the left and right air guide blades.
[0041] Specifically, after the air conditioning system is powered on, it receives an intelligent air supply command from the control module, which can be a remote control or a touchscreen. For example, it operates according to the remote control command. After detecting and receiving a command to allow the air to follow or avoid people, it records the current first operating state of the air conditioner. For example, if the air supply level is A, the swing state is recorded as B. It then controls the left and right guide vanes to move to θ. 止 The position is maintained, and the air conditioning system controls the air supply speed to the low setting.
[0042] Furthermore, the radar module is activated to detect target objects, which can be users or other moving or stationary objects. The radar module detects whether there are moving objects in the current airflow direction of the air conditioner. If no moving objects are found, the air conditioning system continues to operate at fan speed A and swing mode B.
[0043] Preferably, by setting the system to acquire the first operating state of the air conditioner upon receiving a smart air supply command, the current state of the air conditioner can be combined with subsequent commands, making the execution of commands more closely aligned with the current state of the air conditioner. At the same time, a radar module is set to acquire the location information of the target object, enabling the system to quickly determine the current location of the target object. This provides a better and more accurate basis for judging the smart air supply command, allowing the smart air supply command to better serve the user, thereby improving intelligent perception and enhancing the user experience.
[0044] Specifically, after obtaining the current operating status of the air conditioner, the process includes: controlling the air conditioner's air guide vanes to move to the first position and controlling the air supply level to be adjusted to the low setting; wherein, the first position is the maximum sweeping angle of the left and right air guide vanes of the air conditioner.
[0045] Preferably, by setting the air conditioner's air guide vanes to the maximum sweep angle and adjusting the air supply level to a low setting, it prevents easily swaying objects around the air conditioner from swaying due to the air conditioner's airflow during subsequent detection, thus affecting the subsequent radar module's detection, causing misjudgments, impacting the user experience, and ultimately failing to demonstrate the effect of intelligent air supply.
[0046] Specifically, obtaining the location information of the target object through the radar module includes: detecting whether the target object is a moving object; if the target object is not a moving object, controlling the air conditioner to operate in the first operating state; if the target object is a moving object, detecting the number of moving objects; when the number is 1, controlling the air conditioner to execute the first operating mode; when the number is greater than 1, controlling the air conditioner to execute the second operating mode.
[0047] Preferably, a radar module is used to detect whether the target object is a moving object. Different controls are applied to the air conditioner based on the number of moving objects, so that the air conditioner has different execution methods for different numbers of moving objects. This makes the air conditioner more intelligent in its recognition, that is, more comprehensive in its intelligent perception, and thus provides a better user experience under the command of intelligent air delivery.
[0048] Specifically, the first operating state includes the air conditioner's air supply level being the first wind speed. When the quantity is 1, controlling the air conditioner to execute the first operating mode also includes: when the intelligent air supply command is "wind follows people", controlling the air conditioner's air supply level to be adjusted to the first wind speed; obtaining the first angle information of the current target object, and controlling the air conditioner's guide vane angle to remain within a first range, and the first range includes the first angle information; wherein, the first angle information is the angle value between the line connecting the target object and the air conditioner and the plane of the air conditioner.
[0049] Specifically, the first range can be understood as the first angle information ± a threshold, such that the values within the first range are close to or equal to the value of the first angle information.
[0050] Preferably, when the number of moving objects is one and the intelligent air supply command is "wind follows the person", the radar obtains the first angle information of the current target object, and at the same time sets the angle of the air guide blades to be kept within a first range, and the first range includes the first angle information. In this way, the air sweeping range of the air conditioner can be controlled to be controlled close to the target object, that is, to ensure that the air supply can follow the target object and achieve the purpose of "wind follows the person".
[0051] Specifically, the first operating state includes setting the air conditioner's fan speed to the first fan speed. When the quantity is 1, controlling the air conditioner to execute the first operating mode also includes: when the intelligent air supply command is "avoid people," controlling the air conditioner's fan speed to be adjusted to the first fan speed; and recording the maximum angle of movement of the air conditioner's air guide vanes as θ. 止 The minimum angle is denoted as θ.起 ; Obtain the second angle information of the target object, and compare the second angle information with θ 止 The absolute value of the difference is denoted as |△θ|, and a fixed angular error value of △D is defined, where △D is greater than 0. If |△θ| ≥ △D, then the angle of the air guide vanes of the air conditioner is controlled as θ. 止 If |△θ| < △D, then the angle of the air guide vanes controlling the air conditioner is θ. 起 .
[0052] Specifically, the angle error value △D is a manually set value, based on experimental values obtained from actual user experience tests. It can be adjusted according to the actual situation, for example, it can be 10°.
[0053] Preferably, when the number of movements is one and the instruction is "wind avoids people", the second angle information of the target object is obtained and compared with the maximum sweep angle of the guide vane to obtain the difference. This difference is then compared with the angle error to obtain the comparison result. If the difference is greater than or equal to the angle error, it means that the current target object is not at the maximum sweep angle, and air can be delivered at this location to achieve the effect of "wind avoids people". Otherwise, air is delivered at the minimum angle. By obtaining the angle information of the target object and controlling the angle of the guide vane, the effect of intelligent air delivery is achieved. This method is not only simple to control and does not require high-precision infrared radar to achieve the current effect, thus reducing costs, but it still achieves a good intelligent perception effect, making the user experience better.
[0054] Specifically, when the quantity is greater than 1, the air conditioner is controlled to execute the second operating mode, which includes: denoted as θ, the maximum angle of movement of the air conditioner's air guide vanes. 止 Define a fixed angular error value as ΔD, where ΔD is greater than 0; record the third angle information of all current target objects sequentially, denoted as Dn, where n is a natural number greater than 0; compare θ respectively. 止 The difference between the value of ΔDn and the value of ΔD is obtained. The absolute value of the difference is recorded as |ΔDn|. The values of |ΔDn| and ΔD are compared. If |ΔDn| is greater than ΔD, the air conditioner is controlled to perform the first action. If |ΔDn| is less than or equal to ΔD, the air conditioner is controlled to perform the calibration action.
[0055] Specifically, based on the third-angle information of all target objects, records are saved from largest to smallest as D1, D2, D3, and so on, and then compared with θ. 止 Compare and subtract, the difference |△Dn|=|θ 止 -Dn|.
[0056] Preferably, when the number of moving objects is greater than 1, the angle information of all target objects is acquired and compared with the maximum angle value of the air conditioner's air guide vane movement to obtain the difference. By comparing the absolute value of the difference with the angle error, it is determined whether there is a swaying object at the current maximum angle. When the difference is less than or equal to the angle error, it indicates that there may be a misjudgment at the current maximum angle, and further judgment is required. This makes the air conditioner's judgment of swaying objects more accurate. By acquiring the angle and controlling the angle of the air guide vane, it is easier to identify and judge the target object, improving the level of intelligent perception and thus ensuring the user experience.
[0057] Specifically, if |△Dn|≤△D exists, then the air conditioner is controlled to perform a calibration action, including: defining θ 中轴 The maximum angle θ for the movement of the air conditioner's air guide vanes 止 and minimum angle θ 起 The angle between these values forms an intermediate value; the angle of the air conditioner's guide vanes is controlled by θ. 止 Change to θ 中轴 Detect the fourth angle information of all current target objects, denoted as Dn~, where n is a natural number greater than 0; compare θ respectively. 止 The difference between ΔDn and ΔD is calculated, and the absolute value of the difference is denoted as |ΔDn~|. The magnitudes of |ΔDn~| and ΔD are then compared. If |ΔDn~| is greater than ΔD, the target object is determined to be a non-user, and the fourth angle information is θ. 止 The target object ±△D does not record its location information. After clearing the location information of the current target object, the air conditioner is controlled to perform the first action. If there exists |△Dn~|≤△D, then the target object is determined to be the user. After clearing the location information of the current target object, the air conditioner is controlled to perform the first action.
[0058] Specifically, detect the fourth angle information of all current target objects, denoted as Dn~, and record and save it in ascending order of fourth angle information as D1~, D2~, D3~, and so on, and then compare it with θ. 止 The differences are calculated as |△D1|~, |△D2|~, |△D3|~, and so on. The difference |△Dn~| = |θ 止 -Dn~|.
[0059] Specifically, if |△Dn~| are all greater than △D, then the target object is determined to be a non-user, and the fourth angle information is θ. 止 The target object of ±△D does not record the position information. The air conditioner filters out moving objects at that position. That is, when the wind follows the person, it does not need to follow the position to deliver air. When the wind avoids the person, it does not need to avoid the position.
[0060] Preferably, by setting θ中轴 The current angle information of all target objects is compared again to obtain the corresponding difference value, which is then compared with the angle error value. If both are greater than the angle error, it means that the current object will not sway when not blown by the wind, indicating that the current object is a swaying object. Otherwise, it is a user. By changing the angle of the air guide blades and measuring again, misjudgment caused by the swaying of swaying objects due to wind is avoided. There is no need to use infrared radar to identify whether it is a user, which not only reduces costs but also makes the judgment simpler, improves the intelligent perception of the air conditioner, and thus makes the user experience better when using intelligent air supply commands.
[0061] Specifically, the first operating state includes setting the air conditioner's fan speed to the first setting, and controlling the air conditioner to perform the first action, including: when the intelligent fan speed command is "follow the person," adjusting the air conditioner's fan speed to the first setting; acquiring the fifth angle information of all current target objects, denoted as Gn, where n is a natural number greater than 0; and comparing Gn with θ respectively. 中轴 The size; if Gn is less than or equal to θ 中轴 The angle of the air guide vanes of the air conditioner is controlled by θ. 中轴 -θ 起 -θ 中轴 Loop; if Gn is greater than θ 中轴 The angle of the air guide vanes of the air conditioner is controlled by θ. 中轴 -θ 止 -θ 中轴 In the cycle, otherwise, the angle of the air conditioner's guide vanes is controlled to change by θ. 起 -θ 中轴 -θ 止 -θ 中轴 -θ 起 cycle.
[0062] Specifically, the fifth-angle information is recorded from smallest to largest as G1, G2, G3, and so on, and then assigned to θ respectively. 中 Compare.
[0063] Preferably, by setting multiple moving objects and the command is "wind follows person", the angle information of all target objects is obtained and compared with θ. 中轴 By comparing the angle values, it is possible to quickly determine whether the current target object is nearby, and then quickly determine the cycle mode of the current air guide vane sweeping angle. By comparing the air guide angle and the angle value of the target object, the location of the target object and the intelligent air supply sweeping mode as needed are realized more quickly. It is no longer necessary to rely on high-precision infrared radar, which reduces costs, improves the intelligent perception of the air conditioner, and thus ensures the user experience when using intelligent air supply commands.
[0064] Specifically, the first operating state includes setting the air conditioner to the first fan speed and controlling the air conditioner to perform the first action. It also includes: when the intelligent air supply command is "wind avoids people," acquiring the sixth angle information of all current target objects, denoted as Gn~, and comparing Gn~ with θ... 止 Calculate the difference, and take the absolute value of the difference, denoted as |△θn|. If |△θn| is greater than △D, then adjust the air conditioner's fan speed to the first setting, and maintain the air conditioner's guide vane angle at θ. 止 Otherwise, adjust the air conditioner to keep the fan speed low.
[0065] Specifically, record all the information of the sixth angle from smallest to largest, as G1~, G2~, G3~, and so on, and assign them to θ respectively. 止 To perform the difference.
[0066] Preferably, when the air conditioner needs to execute a wind avoidance command, it controls the acquisition of the angle information of all target objects and calculates the difference with the maximum sweeping angle value of the air conditioner's guide vanes. The difference is then compared with the angle error value to quickly determine whether the current position of all target objects will be blown by the wind. If both are greater than the angle error, it means that none of the current target objects are in the air outlet direction of the maximum sweeping angle, and the air outlet in this direction can be maintained to achieve the wind avoidance effect. Conversely, if the difference is less than the angle error, it means that the moving objects are widely distributed and cannot be avoided, so the low fan speed is activated to ensure the user's wind avoidance experience.
[0067] See Figure 2 The present invention also provides an air conditioner 100, which includes: an acquisition module 110, which is used to acquire the first operating state of the air conditioner when the air conditioner receives an intelligent air supply command sent by the control module, and acquire the location information of the target object through a radar module; and a control module 120, which is used to control the operating state of the air conditioner according to the intelligent air supply command, the location information and the first operating state.
[0068] Preferably, the acquisition module 110 acquires the current first operating state of the air conditioner, the intelligent air supply command, and the location information of the target object, so that the subsequent control module 120 can quickly determine the specific control method of the current air conditioner's intelligent air supply command based on the data obtained by the acquisition module 110, thereby improving the intelligent perception level of the air conditioner.
