[0058] Figure 1 It is one of the flow schematic diagrams of the control method of the fan provided by the embodiment of the present invention. Referring to Figure 1 , the control method of the fan provided by the embodiment of the present invention may include:

[0059] Step 110: Determine the target user position according to the ultra-wideband (UWB) positioning information of the target user;

[0060] Step 120: Determine the target rotation angle of the fan according to the target user position;

[0061] Step 130: Rotate the fan to the target air supply position based on the target rotation angle;

[0062] Among them, the target air supply position is determined based on the target user position.

[0063] The execution subject of the control method of the fan provided by the embodiment of the present invention can be an intelligent fan control device. The intelligent fan control device can be an electronic device, and can include: a fan provided with a UWB base station, a UWB mobile terminal provided with a UWB tag, etc. Among them, the UWB mobile terminal provided with a UWB tag, for example, includes: a fan remote control, a UWB device carried by a user, etc. The UWB device carried by the user can be a wearable device, for example, includes: an electronic bracelet or an electronic work permit, etc., and the present invention does not make specific limitations.

[0064] Taking the intelligent fan control device executing the goods allocation status determination method provided by the embodiment of the present invention as an example below, the technical solution of the present invention will be described in detail.

[0065] It should be noted that the Ultra Wide Band (UWB) technology is a wireless carrier communication technology. It does not use a sine carrier, but uses nanosecond-level non-sine wave narrow pulses to transmit data, so the occupied spectrum range is very wide. The UWB technology has the advantages of low system complexity, low transmitted signal power spectral density, insensitivity to channel fading, low interceptability, and high positioning accuracy, and is particularly suitable for high-speed wireless access in dense multipath places such as indoors.

[0066] Optionally, in step 110, the UWB base station in the fan communicates with the UWB tag in the UWB mobile terminal. When the UWB mobile terminal is a UWB device carried by a user, the UWB tag and the UWB base station can establish communication automatically at regular intervals, or the target user can trigger the UWB tag to establish communication with the UWB base station according to needs, or the UWB tag and the UWB base station can establish communication automatically when the distance between them meets the preset device parameters; when the UWB mobile terminal is a fan remote control, the UWB tag can be triggered to establish communication with the UWB base station according to the user's needs. The position of the UWB tag can be regarded as the position where the target user is currently located. Then, within the coverage range of the UWB base station, when the UWB tag and the UWB base station establish communication, the UWB tag sends UWB positioning information to the UWB base station. After receiving the UWB positioning information, the UWB base station can determine the target user position and the target rotation angle of the fan.

[0067] Optionally, in step 120, the target rotation angle of the fan is determined based on the target user position and the current swing angle of the fan. The target user position is determined according to the UWB positioning information, then the target air supply position of the fan is determined according to the target user position, and finally the target rotation angle is determined according to the current air supply position and the target air supply position. It can be assumed that the swing angle of the current air supply position of the fan is 0 degrees, and the angle at which the fan rotates to the target air supply position is the target rotation angle. The fan provided in the embodiment of the present invention can support the fan to turn or swing 360 degrees, and can realize arbitrarily adjusting the rotation angle of the fan without moving the fan, improving the flexibility of adjusting the rotation angle of the fan; it can also expand the air supply range of the fan to meet different requirements of the target user for the air supply range in different situations.

[0068] Optionally, in step 130, the fan can automatically adjust the swing direction according to the target rotation angle until it rotates to the target air supply position.

[0069] For example: when the UWB mobile terminal with the UWB tag is a wearable device, the embodiment of the present invention can be applied to the following scenarios:

[0070] The target user can wear a wearable device and move within the radiation range of the fan UWB base station. The UWB tag in the wearable device can automatically establish a communication connection with the UWB base station. For example, the UWB tag can send location information to the UWB base station, and then the UWB base station in the fan can track the location information of the target user in real time. According to the user's needs, the wearable device can turn on the fan. The fan UWB base station can determine the target rotation angle of the fan based on the current position of the fan and the position of the target user. At this time, the fan can automatically rotate to the target air supply position according to the target rotation angle, and can also adjust the target air supply position according to the position where the target user moves.

[0071] In the case where the UWB mobile terminal equipped with the UWB tag is used as a fan remote control, the embodiments of the present invention can also be applied to the following scenarios:

[0072] The target user turns on the fan through the fan remote control according to the needs. At this time, the UWB base station in the fan will automatically establish a communication connection with the UWB tag in the fan remote control. The UWB base station can determine the position of the target user according to the location information sent by the UWB tag, and further determine the target rotation angle of the fan. The target user can manually control the fan to rotate to the target air supply position through the fan remote control, and the fan can also automatically adjust to the target air supply position according to the target rotation angle.

[0073] Optionally, the application scenarios provided by the embodiments of the present invention are only used as examples and are not specifically limited herein.

[0074] The control method of the fan provided by the embodiments of the present invention can obtain the position of the target user by determining the UWB positioning information of the target user, and then can determine the target rotation angle, so as to realize automatically adjusting the air supply position according to the position of the target user, improving the practicability of the fan; and adjusting the fan to the target air supply position according to the target rotation angle, meeting the user's requirement for the comfort of the fan air supply, and improving the user's use experience.

[0075] In one embodiment, the determining the target rotation angle of the fan according to the position of the target user includes:

[0076] Determining the deviation angle between the current air supply position of the fan and the target air supply position according to the position of the target user;

[0077] Determining the deviation angle as the target rotation angle;

[0078] Wherein, the deviation angle is the included angle between the first angular bisector and the second angular bisector;

[0079] The first angular bisector is the angular bisector of the fan swing angle corresponding to the current air supply position;

[0080] The second angular bisector is the angular bisector of the fan swing angle corresponding to the target air supply position.

[0081] Optionally, as Figure 2 shown, set the initial angle of the first angular bisector of the fan swing angle corresponding to the current air supply position to 0 degrees, and then according to the included angle between the second angular bisector of the fan swing angle corresponding to the target air supply position and the 0-degree angular bisector, the deviation angle between the current air supply position and the target air supply position can be determined. Or consider the fan, the current air supply position, and the target air supply position as three points in the same plane, and set the initial angle of the line where the fan and the current air supply position are located to 0 degrees, then the deviation angle, that is, the target rotation angle, can be determined according to the included angle between the line where the fan and the target air supply position are located and the 0-degree line.

[0082] Optionally, the target rotation angle can be used to adjust the center point of the target air supply position. By adjusting the air supply position, the center point of the target air supply position can be made to correspond to the target user position.

[0083] The control method of the fan provided by the embodiment of the present invention can determine the target rotation angle by determining the deviation angle between the current air supply position and the target air supply position, so as to control the rotation angle of the fan in real time, improve the accuracy of the fan rotation, and also adjust the rotation angle of the fan according to the angular bisector of the air supply position, improving the comfort of the fan blowing.

[0084] In one embodiment, the control method of the fan further includes:

[0085] Determine the distance between the fan and the target user position according to the UWB positioning information;

[0086] When the distance does not exceed the preset distance threshold, control the fan to move following the target user;

[0087] When the distance exceeds the preset distance threshold, control the fan to move based on a preset movement trajectory.

[0088] Optionally, an electric wheel is installed on the fan base, such as a universal wheel or other parts that can realize the moving function. This electric wheel can be installed on the chassis of the fan and play the role of support and movement; at the same time, it also has an electronic braking function to ensure that the fan will not shake arbitrarily. The electric wheel can include a universal wheel and a driving device. The driving device can drive the universal wheel to rotate or turn, so that the fan can move or turn, etc. Since the electric wheel can directly drive the fan to rotate, after determining the target rotation angle, in addition to the fan swinging to the target air supply position by swinging its head, the fan can also be directly controlled to rotate to the target air supply position by the electric wheel.

[0089] Optionally, when the distance does not exceed a preset distance threshold, the intelligent fan control device may send a movement control instruction to the fan. After the driving device receives the control instruction, the driving device drives the electric wheel to rotate or turn, so that the fan moves following the movement of the target user. During the movement of the fan, the UWB base station in the fan and the UWB tag in the direction of the target user always maintain communication, so as to be able to determine the distance between the fan and the target user at any time.

[0090] Optionally, when the distance exceeds the preset distance threshold, that is, the communication between the UWB base station in the fan and the UWB tag in the direction of the target user is in a disconnected state. For example, the fan is in the living room and the target user is in the bedroom, and the UWB base station in the fan cannot establish a connection with the UWB tag in the direction of the target user. Then the fan may control the fan to move based on a preset movement trajectory to search for the signal of the UWB tag in the direction of the target user. During the process of the fan moving according to the preset movement trajectory, the fan may be temporarily turned off and then restarted after the signal of the UWB tag in the direction of the target user is searched. The preset movement trajectory may be preset according to the layout of the location where the fan is located. For example, it may be a movement trajectory determined according to the house type layout where the target user is located.

[0091] Among them, the preset distance threshold may be set according to the coverage range of the UWB base station. The premise for the fan to follow the target user's movement is that the UWB base station in the fan and the UWB tag in the direction of the target user can continuously maintain communication. In addition, a protection distance may also be set during the process of the fan following the target user to prevent the fan from being too close to the target user. For example, when the state of the fan following the target user is turned on, the fan will automatically adjust the distance from the user. Assuming the protection distance can be set to 30 - 40 cm, that is to say, the distance between the fan and the target user being followed can be automatically maintained within the range of 30 - 40 cm. Or during the movement of the fan, it is detected whether the distance between the fan and the target user exceeds the range of 30 - 40 cm or does not exceed the range of 30 - 40 cm, and the fan will automatically adjust the distance from the target user to 30 - 40 cm to ensure that the target user feels a stable air volume.

[0092] The control method of the fan provided by the embodiment of the present invention controls the fan to move following the trajectory of the target user according to the distance between the fan and the target user, realizes continuously following the movement of the target user, and continuously blows air to the target user, improving the user experience.

[0093] In one embodiment, the control method of the fan further includes:

[0094] Adjust the wind speed of the fan according to the distance.

[0095] Optionally, different fan speeds can be set according to the distance between the fan and the target user, so that the air volume felt by the target user at different distances is the same. A mapping table of distance intervals and wind speeds can be preset in advance. When it is detected that the distance between the target user and the fan is within a certain distance interval, the current wind speed of the fan is adjusted to the corresponding wind speed in the mapping table.

[0096] Optionally, the target user can also control the UWB mobile terminal according to needs to adjust the wind speed of the fan through the data communication ability of the UWB mobile terminal.

[0097] The fan control method provided by the embodiments of the present invention can adaptively adjust the air volume by adjusting the wind speed according to the distance, effectively improving the user experience.

[0098] In one embodiment, the target rotation angle includes at least one of the following: the rotation angle in the horizontal direction and the rotation angle in the vertical direction.

[0099] Optionally, since the current air supply position of the target user relative to the fan can be a deviation in the horizontal direction, a deviation in the vertical direction, or a deviation in both the horizontal and vertical directions. Therefore, the target rotation angle can be the rotation angle in the horizontal direction or the rotation angle in the vertical direction.

[0100] Optionally, the fan can determine the phase position with the target user according to the angle detection ability of the UWB base station, so as to determine whether to swing left and right or up and down, so as to adjust the swing angle in the horizontal direction and the pitch angle in the vertical direction of the fan.

[0101] Optionally, the target user can control the rotation of the fan in the horizontal or vertical direction through the UWB mobile terminal according to needs. For example: the user controls the rotation of the fan through the direction setting button on the fan remote control. The target user can also control the height information of the fan through the UWB mobile terminal according to needs, so that the fan can be automatically lifted and lowered. At this time, the fan only needs to adjust the rotation angle in the horizontal direction to rotate to the target air supply position.

[0102] The fan control method provided by the embodiments of the present invention determines the target rotation angles of the fan in the horizontal and vertical directions according to the relative position between the target user and the fan, and then the fan supplies air to the user according to the target rotation angles, which can realize the intelligent air supply function of the fan, so that the user can blow comfortably, greatly improving the user experience.
