Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to a fan, a fan control method, a device, and a computer device. Background Technology

[0002] Existing fan products cannot meet the real-time customized air supply requirements of users. In the same scenario, when there are multiple users with different air supply needs, such as some people being afraid of heat and others being afraid of being cold by the wind, ordinary fans can only deliver air evenly within a certain range by oscillating at a set speed or setting. The air speed is constant and cannot meet the air supply needs of all people at the same time. Summary of the Invention

[0003] In view of this, the present invention provides a fan, a fan control method, a device, and a computer equipment to solve the problem that when there are multiple users with different air supply needs in the same scene, the fan cannot simultaneously meet the air supply needs of all people.

[0004] In a first aspect, the present invention provides a fan control method, comprising the following steps: during the fan oscillation process, acquiring the fan's operating speed and first image information captured by a camera on the fan; acquiring second image information captured by the camera when the fan runs at its maximum oscillation angle for at least one revolution; determining, based on the second image information, whether there are multiple target users within the fan's airflow range; when there are multiple target users within the fan's airflow range, determining, based on the first image information, the current target user that the fan needs to blow over; determining, based on the second image information, the next target user that the fan needs to blow over, and determining the distance between the current target user and the next target user; acquiring the correspondence between target users and airflow requirements, and determining the airflow requirements of the current target user based on the current target user and the correspondence; adjusting the rotational speed of the fan blade motor, the oscillation speed of the up-and-down oscillation motor, and / or the oscillation speed of the left-and-right oscillation motor based on the airflow requirements of the current target user and the distance between the current target user and the next target user.

[0005] The fan control method provided by this invention determines whether there are multiple target users within the fan's airflow range based on second image information captured by a camera when the fan has run at its maximum oscillation angle for at least one revolution. If so, it determines the current target user that the fan needs to blow over based on first image information, and the next target user that the fan needs to blow over based on second image information. Furthermore, it determines the airflow requirements of the current target user based on the current target user and the corresponding relationship, and adjusts the rotation speed of the fan blade motor, the oscillation speed of the up-down oscillation motor, and / or the oscillation speed of the left-right oscillation motor based on the airflow requirements of the current target user and the distance between the current target user and the next target user. This solves the problem that the fan cannot simultaneously meet the airflow needs of all people.

[0006] In one optional implementation, adjusting the speed of the fan motor and / or the up-and-down oscillating motor based on the current target user's airflow requirement and the distance between the current target user and the next target user includes: determining whether the distance between the current target user and the next target user is greater than a preset first threshold; when the distance between the current target user and the next target user is greater than the first threshold, determining whether the current target user's airflow requirement is lower than a first preset requirement; when the current target user's airflow requirement is lower than the first preset requirement, reducing the speed of the fan motor to a first speed, reducing the oscillation speed of the up-and-down oscillating motor to a first oscillation speed, and / or reducing the oscillation speed of the left-and-right oscillating motor. The speed is reduced to the second oscillation speed; wherein the first rotation speed, the first oscillation speed, and / or the second oscillation speed are determined according to the fan's operating gear; when the current target user's airflow requirement is higher than the first preset requirement, the fan motor speed is increased to the second rotation speed, the up-and-down oscillation motor speed is increased to the third oscillation speed, and / or the left-and-right oscillation motor speed is increased to the fourth oscillation speed, wherein the second rotation speed, the third oscillation speed, and / or the fourth oscillation speed are determined according to the fan's operating gear; when the current target user's airflow requirement is equal to the first preset requirement, the fan motor speed, the up-and-down oscillation motor speed, and / or the left-and-right oscillation motor speed remain unchanged.

[0007] In other words, when the distance between the target user and the next target user is greater than a preset first threshold, when the fan oscillates past a user who is not hot (i.e., the current target user's airflow requirement is lower than the first preset requirement), the fan control board will control the fan blade motor to automatically adjust the current airflow speed to decrease, and at the same time, the oscillation speed of the corresponding up-down and left-right oscillation motors will also be appropriately increased, so that the air blown by the fan passes over the user as little as possible; when the fan oscillates past a user who is hot (i.e., the current target user's airflow requirement is higher than the first preset requirement), the fan control board will control the fan blade motor to automatically adjust the current airflow speed to increase, and at the same time, the oscillation speed of the corresponding up-down and left-right oscillation motors will also be appropriately decreased, so that the air blown by the fan passes over the user as little as possible; when the fan oscillates past a user who is cooling (i.e., the current target user's airflow requirement is equal to the first preset requirement), the fan will maintain the preset setting and operate normally at the default oscillation speed.

[0008] In one optional implementation, the fan control method further includes: when the distance between the current target user and the next target user is less than or equal to a first threshold, determining whether the current target user's airflow requirement is lower than a second preset requirement; when the current target user's airflow requirement is lower than the second preset requirement, controlling the up-and-down oscillating motor to be in an up-and-down state or a down-and-up state; when the current target user's airflow requirement is equal to or higher than the second preset requirement, maintaining the rotational speed of the fan blade motor, the oscillation speed of the up-and-down oscillating motor, and / or the oscillation speed of the left-and-right oscillating motor unchanged.

[0009] In other words, when the distance between the current target user and the next target user is less than or equal to the first threshold, the two targets are relatively close. The up-and-down oscillating motor is controlled so that the fan head is oscillating in an up-and-down state, so that it is not blowing directly on the person who does not need the airflow.

[0010] In one optional implementation, the fan control method further includes: determining a target user within the fan's blowing range based on the second image information, and displaying the target user on a display interface according to a preset display rule; obtaining the blowing requirements of the target user input on the display interface, and establishing a correspondence between the target user and the blowing requirements.

[0011] This makes it easy to establish a correspondence between target users and their air-blowing requirements.

[0012] In one optional implementation, the fan control method further includes: when there is only one target user within the fan's blowing range, obtaining the distance between the fan and the target user; when the distance between the fan and the target user is less than or equal to a preset third threshold, keeping the fan motor speed constant; and when the distance between the fan and the target user is greater than the third threshold, increasing the fan motor speed.

[0013] In other words, when the target user moves around, the fan can automatically adjust the speed of the fan blade motor to improve the target user's experience.

[0014] In one optional implementation, when the distance between the fan and the target user is greater than a third threshold, increasing the speed of the fan motor includes: determining the amount of increase in the speed of the fan motor based on the distance between the fan and the target user, wherein the amount of increase is determined based on the distance between the fan and the target user; and increasing the speed of the fan motor based on the amount of increase.

[0015] In other words, the fan can adjust the speed of the fan blade motor according to the distance between the fan and the target user, so that the target user can achieve the best airflow experience no matter where they move.

[0016] Secondly, the present invention also provides a fan control device, the device comprising a first acquisition module, a second acquisition module, a judgment module, a current target user determination module, a distance calculation module, a blowing requirement determination module, and a first adjustment module; the first acquisition module is used to acquire the fan's operating speed and first image information captured by the fan's camera during the fan's oscillation process; the second acquisition module is used to acquire second image information captured by the camera when the fan runs at its maximum oscillation angle for at least one revolution; the judgment module is used to determine whether there are multiple target users within the fan's blowing range based on the second image information; the current target user determination module is used to determine the current target user when the fan's blowing... When multiple target users exist within the range, the current target user that the fan needs to blow over is determined based on the first image information; the distance calculation module is used to determine the next target user that the fan needs to blow over based on the second image information, and to determine the distance between the current target user and the next target user; the blowing requirement determination module is used to obtain the correspondence between target users and blowing requirements, and to determine the blowing requirements of the current target user based on the current target user and the correspondence; the first adjustment module is used to adjust the rotation speed of the fan motor, the oscillation speed of the up-and-down oscillation motor, and / or the oscillation speed of the left-and-right oscillation motor based on the blowing requirements of the current target user and the distance between the current target user and the next target user.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0032] According to an embodiment of the present invention, a fan control method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0033] This embodiment provides a fan control method that can be used in computer equipment. Figure 1 This is a flowchart of a fan control method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0034] Step S101: During the fan oscillation process, acquire the fan's operating speed and the first image information captured by the fan's camera.

[0035] Step S102: Obtain the second image information captured by the camera when the fan runs at its maximum oscillation angle for at least one revolution.

[0036] Step S103: Determine whether there are multiple target users within the fan's airflow range based on the second image information.

[0037] Step S104: When there are multiple target users within the fan's blowing range, determine the current target user that the fan needs to blow over based on the first image information.

[0038] Step S105: Determine the next target user that the fan needs to blow over based on the second image information, and determine the distance between the current target user and the next target user.

[0039] Step S106: Obtain the correspondence between target users and air blowing requirements, and determine the air blowing requirements of the current target user based on the current target user and the correspondence.

[0040] Step S107: Adjust the speed of the fan motor, the oscillation speed of the up-and-down oscillation motor, and / or the oscillation speed of the left-and-right oscillation motor according to the blowing requirements of the current target user and the distance between the current target user and the next target user.

[0041] The fan control method provided in this embodiment determines whether there are multiple target users within the fan's airflow range based on the second image information captured by the camera when the fan runs at its maximum oscillation angle for at least one revolution. If so, it determines the current target user that the fan needs to blow over based on the first image information and the next target user that the fan needs to blow over based on the second image information. Furthermore, it determines the airflow requirements of the current target user based on the current target user and the corresponding relationship, and adjusts the speed of the fan blade motor, the oscillation speed of the up-down oscillation motor, and / or the oscillation speed of the left-right oscillation motor based on the airflow requirements of the current target user and the distance between the current target user and the next target user. This solves the problem that the fan cannot simultaneously meet the airflow needs of all people.

[0042] This embodiment provides a fan control method that can be used in computer equipment. Figure 2 This is a flowchart of another fan control method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0043] Step S201: During the fan oscillation process, acquire the fan's operating speed and the first image information captured by the fan's camera.

[0044] Step S202: Obtain the second image information captured by the camera when the fan runs at its maximum oscillation angle for at least one revolution.

[0045] Step S203: Determine whether there are multiple target users within the fan's airflow range based on the second image information.

[0046] Step S204: When there are multiple target users within the fan's blowing range, determine the current target user that the fan needs to blow over based on the first image information.

[0047] Step S205: Determine the next target user that the fan needs to blow over based on the second image information, and determine the distance between the current target user and the next target user.

[0048] Step S206: Obtain the correspondence between target users and air blowing requirements, and determine the air blowing requirements of the current target user based on the current target user and the correspondence.

[0049] In one optional implementation, the correspondence between the target user and the air blowing request can be obtained by the following method: determining the target user existing within the air blowing range of the fan based on the second image information, and displaying the target user on the display interface according to the preset display rules; obtaining the air blowing request of the target user entered on the display interface, and establishing the correspondence between the target user and the air blowing request.

[0050] Step S207: Adjust the speed of the fan motor, the oscillation speed of the up-and-down oscillation motor, and / or the oscillation speed of the left-and-right oscillation motor according to the blowing requirements of the current target user and the distance between the current target user and the next target user.

[0051] In one optional implementation, adjusting the rotational speed of the fan motor, the oscillation speed of the up-and-down oscillation motor, and / or the oscillation speed of the left-and-right oscillation motor based on the current target user's airflow requirements and the distance between the current target user and the next target user includes the following:

[0052] Step S2071: Determine whether the distance between the current target user and the next target user is greater than a preset first threshold; if the distance between the current target user and the next target user is greater than the first threshold, proceed to step S2072; otherwise, proceed to step S2076.

[0053] Step S2072: Determine whether the current target user's air blowing requirements are lower than the first preset requirements.

[0054] Step S2073: When the current target user's air blowing requirement is lower than the first preset requirement, reduce the speed of the fan motor to the first speed, reduce the oscillation speed of the up-down oscillation motor to the first oscillation speed, and / or reduce the oscillation speed of the left-right oscillation motor to the second oscillation speed; wherein the first speed, the first oscillation speed and / or the second oscillation speed are determined according to the fan's operating speed.

[0055] Step S2074: When the current target user's air blowing requirement is higher than the first preset requirement, increase the speed of the fan motor to the second speed, increase the oscillation speed of the up-down oscillation motor to the third oscillation speed, and / or increase the oscillation speed of the left-right oscillation motor to the fourth oscillation speed; wherein the second speed, the third oscillation speed and / or the fourth oscillation speed are determined according to the fan's operating speed.

[0056] Step S2075: When the current target user's blowing requirement is equal to the first preset requirement, keep the fan motor speed, the up-and-down oscillation motor speed and / or the left-and-right oscillation motor speed unchanged.

[0057] Steps S2071 to S2075 above can be understood as follows: When the distance between the target user and the next target user is greater than a preset first threshold, when the fan oscillates past a user who is not hot (i.e., the current target user's airflow requirement is lower than the first preset requirement), the fan main control board will control the fan blade motor to automatically adjust the current wind speed to decrease, and at the same time, the oscillation speed of the corresponding up-down and left-right oscillation motors will also be appropriately increased, so that the air blown by the fan passes over the user as little as possible; when the fan oscillates past a user who is hot (i.e., the current target user's airflow requirement is higher than the first preset requirement), the fan main control board will control the fan blade motor to automatically adjust the current wind speed to increase, and at the same time, the oscillation speed of the corresponding up-down and left-right oscillation motors will also be appropriately decreased, so that the air blown by the fan passes over the user as little as possible; when the fan oscillates past a user who is cooling (i.e., the current target user's airflow requirement is equal to the first preset requirement), the fan will maintain the preset setting and operate normally at the default oscillation speed.

[0058] Step S2076: Determine whether the current target user's air blowing requirement is lower than the second preset requirement; if the current target user's air blowing requirement is lower than the second preset requirement, proceed to step S2077; otherwise, proceed to step S2078.

[0059] Step S2077: Control the up-and-down oscillation motor to be in the head-up or head-down state;

[0060] Step S2078: Keep the rotation speed of the fan motor, the oscillation speed of the up-down oscillation motor and / or the oscillation speed of the left-right oscillation motor constant.

[0061] Steps S2071, S2076 to S2078 above can be understood as follows: when the distance between the current target user and the next target user is less than or equal to the first threshold, the two targets are relatively close. The up and down oscillating motor is controlled so that the fan head is oscillating to an up or down state, so that it is not blowing directly on the person who does not need the airflow.

[0062] This embodiment provides a fan control method that can be used in computer equipment. Figure 3 This is a flowchart of another fan control method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps:

[0063] Step S301: During the fan oscillation process, acquire the fan's operating speed and the first image information captured by the fan's camera.

[0064] Step S302: Obtain the second image information captured by the camera when the fan runs at its maximum oscillation angle for at least one revolution.

[0065] Step S303: Determine whether there are multiple target users within the fan's airflow range based on the second image information; if there are multiple target users within the fan's airflow range, proceed to step S304; otherwise, proceed to step S308.

[0066] Step S304: When there are multiple target users within the fan's blowing range, determine the current target user that the fan needs to blow over based on the first image information.

[0067] Step S305: Determine the next target user that the fan needs to blow over based on the second image information, and determine the distance between the current target user and the next target user.

[0068] Step S306: Obtain the correspondence between target users and air blowing requirements, and determine the air blowing requirements of the current target user based on the current target user and the correspondence.

[0069] Step S307: Adjust the speed of the fan motor, the oscillation speed of the up-and-down oscillation motor, and / or the oscillation speed of the left-and-right oscillation motor according to the blowing requirements of the current target user and the distance between the current target user and the next target user.

[0070] Step S308: When there is only one target user within the fan's airflow range, obtain the distance between the fan and the target user.

[0071] Step S309: When the distance between the fan and the target user is less than or equal to the preset third threshold, keep the fan motor speed constant;

[0072] Step S310: When the distance between the fan and the target user is greater than the third threshold, increase the speed of the fan motor.

[0073] In one optional implementation, when the distance between the fan and the target user is greater than a third threshold, increasing the speed of the fan motor includes: determining the amount of increase in the speed of the fan motor based on the distance between the fan and the target user, wherein the amount of increase is determined based on the distance between the fan and the target user; and increasing the speed of the fan motor based on the amount of increase.

[0074] To explain the methods of steps S306 to S310 more clearly, a specific example is given. Figure 4 This is a front view of the fan; Figure 5 This is a side view of the fan. (For example...) Figure 4 and Figure 5As shown, the fan is equipped with a camera 1, a radar module 2, a left-right oscillation motor 3, a right-up-down oscillation motor 4, fan blades 5, a fan blade motor 6, a display screen 7, and a WIFI module. Users can use a mobile app to connect to the fan's main control board via the fan's WIFI module. The app can display the location of people identified by the image recognition module, and users can individually set their desired airflow settings (e.g., not hot, hot, cooling) by clicking on the app. Users can preset an initial setting.

[0075] Figure 6 This is a flowchart of an example of fan control method one, such as... Figure 6 As shown, the camera identifies the outline details of the person being tracked, and the radar module determines the distance between the user and the fan in real time. When the camera detects movement, the fan's main control board coordinates the up-down and left-right oscillation motors to ensure the fan head is aligned with the person's position in real time, oscillating within the body's range so that the person can feel the breeze at all times.

[0076] Furthermore, when a person moves around, the radar module quickly makes a judgment and response. When a person approaches the fan at a distance of ≤1m, the fan control board will control the fan motor to maintain the user's preset airflow speed; when a person moves away from the fan at a distance >1m but ≤2m, the fan control board will control the fan motor to appropriately increase its speed, increasing the output airflow speed by 0.5m / s based on the set speed; when a person moves away from the fan at a distance >2m, the fan control board will control the fan motor to further increase its speed, increasing the output airflow speed by 1m / s based on the set speed. This ensures that the user achieves the best airflow experience regardless of their location or distance.

[0077] It should be noted that the above control method assumes the user has preset the airflow level. The displayed level remains unchanged, making minor adjustments within the preset speed range. For example, if the user currently sets it to level 3, which corresponds to a wind speed of 5 m / s, the fan will maintain a speed of 5 m / s when the user is ≤1m away. When the user moves further away (>2m / s), the wind speed will increase to 6 m / s, but the fan will always display level 3 throughout this process, without any sudden jumps in level or large fluctuations in wind speed. This control method allows for minor adjustments to the preset wind speed within the range of 0-1 m / s, avoiding excessive changes that could lead to increased noise or sudden changes in fan speed, resulting in a poor user experience.

[0078] In this embodiment, when multiple target users are within the fan's airflow range, the fan can adjust the speed of the fan blade motor, the oscillation speed of the vertical oscillation motor, and / or the oscillation speed of the horizontal oscillation motor based on the current target user's airflow requirements and the distance between the current target user and the next target user. This solves the problem that the fan cannot simultaneously meet the airflow needs of all people. Furthermore, when only one target user is within the fan's airflow range and the target user is moving, the fan can automatically adjust the speed of the fan blade motor to improve the target user's experience. Specifically, the fan blade motor speed can be adjusted based on the distance between the fan and the target user, ensuring that the target user experiences optimal airflow regardless of their location.

[0079] This embodiment also provides a fan control device for implementing the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0090] In some optional embodiments, the fan control device further includes a correspondence establishment module.
