Data is transmitted by using non-sine wave narrow pulses of nanosecond to microsecond level.
At present, the turning directions of most fans and the wind speeds of the fans need to be manually adjusted by users during working, so that the fans cannot change working states along with the movement of people after the users move, and not only is the user experience influenced, but also resources are wasted.
In view of the foregoing problems, embodiments of the present application provide a fan control method and a related product, and the following describes embodiments of the present application in detail with reference to the accompanying drawings.

Referring to fig. 2a, fig. 2a is a schematic flowchart of a fan control method according to an embodiment of the present application, applied to a fan provided with an ultra wideband UWB transceiver.
And S201, receiving UWB signals sent by UWB equipment of a user through the UWB transceiver.

As for the method of determining whether the transmitting device and the UWB transceiver are matched, a number may be set in advance for the UWB device matched with the UWB transceiver and stored in the database, the number of the transmitting device may be inquired when the UWB device determines the transmitting device transmitting the UWB signal, and if the number of the transmitting device is not inquired or the inquired number of the transmitting device is not stored in the database, it may be determined that the transmitting device and the UWB transceiver are not matched.
S202, determining position information of the UWB device according to the UWB signal, wherein the position information comprises an angle of the UWB device relative to the fan and a distance of the UWB device relative to the fan.
After the fan receives the UWB signal through the UWB transceiver, the fan can calculate the UWB signal according to a calculating unit in the fan, and the angle and the distance of the UWB equipment relative to the UWB transceiver are obtained. The angle and distance of the UWB device relative to the UWB transceiver may be set to the angle and distance of the UWB device relative to the fan. The distance and the angle between the UWB transceiver and the fan center of the fan can be determined firstly, and then the angle and the distance between the UWB device and the fan can be determined by combining the angle and the distance between the UWB device and the UWB transceiver. Since the UWB device is carried around by the user, the location information of the UWB device may correspond to the location information of the user. Of course, after receiving the UWB signal through the UWB transceiver, the fan may also generate the UWB signal to other computing devices, and the other computing devices calculate the position information of the UWB device according to the position signal of the fan and then transmit the position information to the fan.
S203, adjusting the rotation direction of the fan according to the angle, and adjusting the wind speed of the fan according to the distance.

The wind speed of the fan can be properly adjusted according to the distance between the user and the fan, for example, when the distance between the user and the fan is far away, the wind speed of the fan can be adjusted to be large, so that the user can blow wind with proper wind volume at the position, and the proper wind volume can be set according to the requirements of the user or can be automatically adjusted according to the current physical condition and the ambient temperature of the user. The direction of the fan can be independently adjusted or the wind speed of the fan can be independently adjusted, so that the user can blow the wind with the proper wind quantity at the current position, and the direction of the fan and the wind speed of the fan can be adjusted in a combined manner, so that the user can blow the wind with the proper wind quantity at the current position.
In a specific implementation, when the UWB device includes a plurality of UWB devices, that is, when the UWB transceiver receives UWB signals sent by a plurality of different UWB devices, the adjusting the steering of the fan according to the angle and the adjusting the wind speed of the fan according to the distance may include: acquiring position information of each UWB device in a plurality of UWB devices; determining a first UWB device with a largest angle relative to the fan and a second UWB device with a smallest angle relative to the fan according to the position information of each UWB device; determining whether the maximum coverage of the fan can include both the first UWB device and the second UWB device; if yes, adjusting the steering of the fan according to the angles of the first UWB device and the second UWB device relative to the fan respectively; if not, determining a third UWB device according to the position information of each UWB device and the maximum coverage area, and adjusting the steering of the fan according to the angle of the third UWB device relative to the fan, wherein the third UWB device is at least one of the UWB devices. And/or, obtaining location information of each UWB device in the plurality of UWB devices; determining a fourth UWB device closest to the fan and a fifth UWB device farthest from the fan according to the position information of each UWB device; determining a wind intensity at the position of the fourth UWB device when the wind intensity at the position of the fifth UWB device is a first preset value; if the wind intensity at the position of the fourth UWB device is not larger than a second preset value, adjusting the wind speed of the fan according to the distance between the fourth UWB device and the fifth UWB device relative to the fan; if the wind intensity at the position of the fourth UWB device is greater than the second preset value, determining a sixth UWB device according to the position information of each UWB device, and adjusting the wind speed of the fan according to the distance between the sixth UWB device and the fan, wherein the sixth UWB device is at least one of the UWB devices.
It can be seen that, in the embodiment of the present application, firstly, the UWB transceiver receives the UWB signal sent by the UWB device of the user, then, the position information of the UWB device is determined according to the UWB signal, the position information includes the angle of the UWB device relative to the fan and the distance of the UWB device relative to the fan, finally, the direction of the fan is adjusted according to the angle, and the wind speed of the fan is adjusted according to the distance. Therefore, the fan control method can change the steering direction and the current wind speed of the fan along with the movement of a user holding the UWB equipment, not only can the user requirements be met, the user use experience is improved, but also resources can be saved.
In one possible example, the UWB transceiver includes a first antenna and a second antenna, and the UWB transceiver is disposed on a first component of the fan, the first component being a component of the fan other than a component that rotates following a rotation mechanism of the fan, the determining the position information of the UWB device from the UWB signal includes: determining a first phase of said UWB device with said first antenna from said UWB signal received by said first antenna; determining a second phase of the UWB device with the second antenna from the UWB signal received by the second antenna; determining an angle of the UWB device relative to the fan and a distance of the UWB device relative to the fan from the first phase and the second phase.
Wherein the first component does not rotate with the fan's rotating mechanism means that when the fan is swinging left and right or the fan blades of the fan are rotating, the UWB device remains stationary, that is, the UWB device is not located where the fan is rotatable. Because the UWB device comprises at least two antennas, after the UWB device sends a UWB signal, the first antenna and the second antenna can both receive the UWB signal sent by the UWB device, the first antenna can determine a first phase of the UWB device and the first antenna according to the received UWB signal, similarly, the second antenna can determine a second phase of the UWB device and the second antenna according to the received UWB signal, and finally, the difference between the first phase and the second phase is determined, and the angle and the distance of the UWB device relative to the UWB transceiver are calculated. As shown in fig. 2b, fig. 2b is a schematic diagram of a position information calculating method provided in the embodiment of the present application, and values of y and x may be calculated according to the following formulas:
Figure BDA0002671764720000071
in the figure, α is a first phase, β is a second phase, d is a distance between the first antenna and the second antenna, x is a transverse distance between the first antenna and the UWB device, y is a longitudinal distance between the UWB device and the first antenna and the second antenna, r is a distance calculated from a time from transmission of the UWB signal to reception by the first antenna, and p is a distance value converted from a phase difference calculated from the first phase α and the second phase β.
Therefore, in the embodiment, the angle and the distance of the UWB relative to the UWB equipment are calculated according to the phases of the first antenna, the second antenna and the UWB equipment, so that the calculation is fast, the error of the calculation result is small, and the user requirements can be met.
In one possible example, the UWB device includes a third antenna, and the UWB device is disposed in a second part of the fan, the second part being configured to rotate with a rotation mechanism of the fan, the determining the position information of the UWB device according to the UWB signal includes: determining a third phase of said UWB device with said third antenna from said UWB signal received by said third antenna at a first time; determining a fourth phase of said UWB device and said third antenna from said UWB signal received by said third antenna at a second time, wherein said first time is separated from said second time by a predetermined time period; determining an angle of the UWB device relative to the fan and a distance of the UWB device relative to the fan from the third phase and the fourth phase.
The rotation of the second component along with the mechanism of the fan may be that the UWB device is located on the fan surface of the fan and rotates left and right along with the fan surface portion of the fan, or that the second component is located on the fan blade of the fan and rotates along with the fan blade of the fan. And receiving the UWB signals once every other preset time period, calculating a third phase and a fourth phase according to the UWB signals received twice every two adjacent times, and calculating the angle and the distance of the UWB equipment relative to the fan according to the third phase and the fourth phase.
Therefore, in the embodiment, the angle and the distance of the UWB equipment relative to the fan are calculated according to the UWB signals received by the same antenna at different times, so that the calculation is fast, the error of the calculation result is small, and the user requirements can be met.
In one possible example, before receiving, by the UWB transceiver, a UWB signal transmitted by a UWB device of a user, the method further comprises: determining a mobile frequency of the UWB device; determining a time period according to the moving frequency; and sending request information to the UWB equipment according to the time period.
Wherein determining the mobile frequency of the UWB device comprises: the method comprises the steps of obtaining position information of the UWB equipment in a preset time period, determining a first moving frequency of the UWB equipment in the time period according to the position information, and estimating the moving frequency of the UWB equipment according to the first moving frequency. Or after receiving UWB signals of preset times, determining a second moving frequency of the UWB equipment within the preset times according to the position information of the UWB equipment every time in the preset times, and estimating the moving frequency of the UWB equipment according to the second moving frequency. The time period may be a time interval for receiving the UWB signal when the moving frequency of the UWB device is low, for example, the time interval is longer when the moving frequency of the UWB device is low. The time period may also be a time period including a plurality of times, and after receiving the signal according to the last time is performed, the UWB signal is received from the first time. Before the UWB receiver receives the UWB signal, the UWB transceiver may transmit a request signal, and the UWB device may transmit the UWB signal after receiving the request signal.
Therefore, in this example, the time for sending the request information is determined according to the mobile frequency of the UWB device, so that the power and the internal resources of the UWB transceiver can be saved on the basis of meeting the user requirements.
In one possible example, the determining the time period for sending the request information according to the mobile frequency includes: dividing the time in one time period into a plurality of moments, wherein each moment corresponds to a moving frequency, and the lower the moving frequency is, the later the moment is; and when the moving frequency is M, determining the cut-off time of the time period as the time corresponding to M.
The time period includes a plurality of time instants, and the time interval between each two adjacent time instants is different and is longer the later. The lower the frequency of movement, the later the moment. And when the time within one period is over, the request signal is sent from the first time again, and the ending time of each period is determined according to the currently determined moving frequency, that is, the ending time of each period is different because the moving frequency is changing. For example, if the current moving frequency is 3, the ending time of the current period is the time corresponding to 3, and the period ends until the time is reached and the request signal is sent. The request signal will be re-transmitted from the first time thereafter, and the subsequent time period will end at a time corresponding to 3 unless the moving frequency changes.
Therefore, in this example, the time interval for the UWB device to send the request signal is determined according to the mobile frequency, so that the power and the internal resources of the UWB transceiver can be saved on the basis of meeting the user requirement.
In one possible example, the fan is communicatively connected to a control terminal, and the determining the location information of the UWB device according to the UWB signal includes: transmitting the UWB signal to the control terminal; and acquiring the position information of the UWB equipment returned by the control terminal.
The control terminal can be a computer, a mobile phone, a router and other devices which can be used for calculation. Referring to fig. 2c, fig. 2c is a schematic diagram of a data processing system according to an embodiment of the present application. As shown, data processing system 200 includes a fan 210 and a control terminal 230, with fan 210 and control terminal 230 being coupled. The fan 210 further includes a UWB transceiver 220, the UWB transceiver 220 may directly send the UWB signal to the control terminal 230 or send the UWB signal to the control terminal 230 through the fan 210 after receiving the UWB signal, and the control terminal 230 calculates an angle and a distance of the UWB device relative to the fan according to the UWB signal after receiving the UWB signal, and sends the calculated angle and distance to the fan 210, so that the fan 210 can adjust a turning direction and a wind speed of the fan according to the angle and the distance.
It can be seen that in the present example, the angle and distance of the UWB device relative to the fan are determined by the control terminal, which can reduce the amount of calculation of the fan and make the sensitivity of the fan higher.
In one possible example, the UWB signal contains vital sign data of a user, and the adjusting of the fan's direction of rotation according to the angle and the fan's speed according to the distance comprises: determining a first area according to the sign data, wherein the first area is a partial area of a body of a user; acquiring relative position information of the UWB device and the first area, wherein the relative position information comprises a relative angle and a relative distance of the UWB device and the first area; determining the steering range of the fan according to the angle and the relative angle; determining the wind speed range of the fan according to the distance and the relative distance; determining the final steering direction of the fan and the final wind speed of the fan according to the steering range and the wind speed range; and adjusting the rotation direction of the fan according to the final rotation direction and adjusting the wind speed of the fan according to the final wind speed.
The physical sign data comprises body temperature of each part of the body surface of the user, current physical conditions of the user and the like, wherein the physical conditions comprise diseased or injured conditions. The first region is a portion of a region on the user's body, such as the user's head region or right foot region. Because user's body surface data can be along with ambient temperature change to by the user perception, and the body surface temperature of the different regions of health is different, so user's perception experience is also different, for example when ambient temperature is 23 ℃, the skin temperature of forehead is 33 ~ 34 ℃, the trunk is 32 ℃, the hand is 30 ℃, the perception experience of user can be better when being sufficient 27 ℃. Therefore, the body of the user can be divided into a plurality of areas, an appropriate temperature for each area is set, when the temperature of one or a plurality of areas of the user displayed by the physical sign data is higher than the appropriate temperature of the area, the turning direction and the wind speed of the fan are adjusted, so that the fan can mainly face the area, and the temperature of the area can quickly return to the appropriate temperature after the user blows the wind blown by the fan. Or when the sign data indicates that the user is currently in a cold phase, the fan may turn down the wind speed and turn the fan to a position further away from the user's head.
In the specific implementation, after physical sign data of a user are received, the fan calculates the wind strength which can be accepted by each part of the body of the user, the area with the wind strength smaller than the preset value is determined as the area which can not blow air, the steering range and the wind speed range of the fan are determined according to the wind strength which can be accepted by each part, and finally the final steering and final wind speed of the fan are calculated. The method for calculating the wind strength acceptable for each part of the user identity comprises the following steps: determining body surface temperature values of all parts of the body of the user according to the physical sign data; obtaining body surface proper temperature values aiming at all parts of the body of the user, wherein the body surface proper temperature values can be set by the user, and can also be the body constitution of the user and the body constitution of other users with normal body constitutions shown by combining the physical sign data of the userThe suitable temperature mean value is calculated, for example, if the physical sign data of the user indicates that the physique of the user is a cold physique, the suitable temperature values of the user at the left foot and the right foot are higher than the suitable temperature mean values of other users with normal physiques. After the appropriate temperature value is obtained, the body part with the body surface temperature value lower than the preset threshold value can be determined as the area which can not be blown. For example, when the fan has a turning range [ X ]1～Xn]The wind speed range of the fan is [ Y ]1～Yn]When the wind strength at the first area is S1The wind strength at the second region is S2Then, the final turning direction X of the fan and the final wind speed Y of the fan can be obtained by the following formula:
S1＝aX·bY，S2＝aX·bY
wherein aX is S1Or S2The wind area of (b) is S1Or S2A and b are constant. Therefore, the turning direction of the fan and the wind speed of the fan can be adjusted simultaneously, and the current perception experience of a user is good.
