The embodiment of the application provides a fan control method, a fan control system, a fan and a computer readable storage medium. The fan control method can be applied to a fan or a central control device, wherein the fan can be a table fan, a floor fan, a wall fan and the like. The air supply of the fan can be normal temperature air, warm air or cold air; the central control equipment can be electronic equipment such as a mobile phone, a tablet personal computer, a notebook computer, a desktop computer, a television and the like, and also can be intelligent equipment such as an intelligent refrigerator, an intelligent air conditioner, an intelligent washing machine and the like. The following explanation takes the fan control method applied to a fan as an example.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a fan control method according to an embodiment of the present disclosure.
As shown in fig. 2, the fan control method includes steps S101 to S104.
Step S101, whether the rotation of fan blades of the fan is abnormal or not is monitored.
After the fan is started, the fan blades on the fan start to rotate, the abnormality sensor positioned on the fan starts to work, and the abnormality sensor is used for monitoring whether the rotation of the fan blades is abnormal or not. When the abnormal rotation of the fan blades is monitored, the abnormal sensor sends an abnormal rotation prompt to a processor of the fan, so that the processor can perform subsequent processing based on the abnormal rotation prompt. The abnormality sensor includes, but is not limited to, a rotation speed sensor or a vibration sensor.
In one embodiment, the abnormality sensor on the fan sends the collected operation data of the fan blades to a processor of the fan in real time, and the processor analyzes the operation data to determine whether the rotation of the fan blades is abnormal. Or the rotation data of the fan blades collected by the abnormality sensor is sent to the central control device in real time through the communication interface of the fan, and the central control device judges whether the rotation of the fan blades of the fan is abnormal or not. The central control equipment can be an intelligent refrigerator or an intelligent television.
In one embodiment, a user controls the fan to be started through a button, a control, a remote controller or an operation page, and after the fan is started, the rotation information of the fan blades is collected, and whether the rotation information of the fan blades accords with the rotation information during normal rotation is determined, so that whether the rotation of the fan blades is abnormal is determined.
Specifically, monitoring whether the vibration frequency of the fan blade is abnormal during rotation, namely acquiring the vibration frequency of the fan blade of the fan and acquiring gear information of the fan; according to the gear information, searching a vibration frequency range corresponding to the gear information from a preset vibration frequency table; if the vibration frequency of the fan blade during rotation is not within the vibration frequency range, judging that the vibration frequency of the fan blade during rotation is abnormal. The preset vibration frequency table may be set according to a specific situation, which is not specifically limited in the present application.
Illustratively, the gear information of the fan includes a first gear, a second gear and a third gear, the larger the gear of the fan is, the larger the wind force blown by the fan is, the larger the fan blade rotation rate of the fan is, and accordingly, the higher the vibration frequency when the fan blade rotates is. When the gear of the fan is the third gear, a vibration frequency range corresponding to the third gear is pre-stored in the vibration frequency table, for example, the vibration frequency range is 100 to 120 hz, when the fan encounters external force or an external wind source, the vibration frequency when the fan blades rotate is correspondingly reduced to 90 hz, and at this time, the vibration frequency is not located in the vibration frequency range, and it is determined that the vibration frequency when the fan blades rotate is abnormal.
In one embodiment, the method for monitoring whether there is an abnormality in the rotation of the fan blades may be: and monitoring whether the rotating speed of the fan blades is abnormal or not. The method comprises the steps of acquiring the rotating speed variation of fan blades within preset time, and determining whether the rotating speed variation is greater than a preset rotating speed variation threshold value; if the rotating speed variation is larger than a preset rotating speed variation threshold, determining whether the gear of the fan is adjusted within preset time; if the gear of the fan is not adjusted within the preset time, the rotating speed of the fan blade is judged to be abnormal.
The rotating speed variation is an absolute value of a difference between a starting rotating speed and an ending rotating speed of the fan blade within a preset time, and it should be noted that the preset time can be set according to specific conditions, and this is not specifically limited in this application, and optionally, the preset time is 3 seconds. In addition, the preset rotation speed variation threshold may also be set according to specific situations, which is not specifically limited in this application. When the rotating speed variation is greater than a preset rotating speed variation threshold, determining whether the rotating speed variation is caused by gear variation of the fan, namely determining whether the gear of the fan is adjusted within the preset time, and if the gear of the fan is adjusted within the preset time, judging that the rotating speed of the fan blade during rotation is normal; if the gear of the fan is not adjusted within the preset time, the rotation speed change may be caused by an external force, that is, it is considered that the rotation speed of the fan blade is abnormal.
It should be noted that, the explanation is given to the determination of whether or not there is an abnormality in the rotation of the fan blades by taking the vibration frequency or the rotation speed of the fan blades during rotation monitoring as an example, but the determination of whether or not there is an abnormality in the rotation of the fan blades is not limited to these two methods.
Step S102, if the rotation of the fan blades is abnormal, obtaining a decibel value of noise emitted by the fan, and judging whether the decibel value is greater than a first preset decibel threshold value.
If the fan blade is judged to rotate abnormally, the decibel value of noise emitted by the fan is collected through a decibel detector positioned on the fan, and whether the decibel value is larger than a first preset decibel threshold value is judged through a processor of the fan, wherein the decibel detector can be a sound level meter, a frequency analyzer, a sound intensity analyzer and the like, the first preset decibel threshold value can be set according to specific conditions, the method is not specifically limited, and optionally the first preset decibel threshold value is 80 decibels.
In an embodiment, the first preset decibel threshold is obtained by: and acquiring a decibel value of the environmental noise when the rotation of the fan blade is not abnormal, and taking the decibel value of the environmental noise as a first preset decibel threshold value. Wherein, the decibel value of the environmental noise can be the average decibel value of the environmental noise when the rotation of the fan blade is not abnormal; for example, if it is determined that the time corresponding to the abnormal rotation of the fan blade is 20: 20, the decibel value of the environmental noise when the abnormal rotation of the fan blade is not present is obtained, and the decibel value of the environmental noise when the time is 20: 20 is taken as the first preset decibel threshold. It can be understood that, when the corresponding time is the night time, the decibel value of the ambient noise is smaller, and the obtained first preset decibel threshold is also smaller.
And S103, when the decibel value is larger than a first preset decibel threshold value, controlling the fan to rotate along the horizontal direction, and recording the decibel value of the noise of the fan at each yaw angle.
And when the decibel value of the noise emitted by the fan is greater than a first preset decibel threshold value, controlling the fan to rotate along the horizontal direction, and recording the decibel value of the noise of the fan at each yaw angle. The range of the yaw angle may be [30 °,150 ° ], and it should be noted that if the decibel value is greater than the first preset decibel threshold value, it is considered that noise generated by the fan affects a user, and the decibel value of the noise of the fan at each yaw angle is required so as to know that the decibel value of the noise generated when the fan is biased to any angle is small, so that air supply of the fan is correspondingly controlled, and the intelligence of the fan is improved.
In an embodiment, when the decibel value of the noise emitted by the fan is less than or equal to the first preset decibel threshold, it indicates that the decibel value of the noise emitted by the fan is not high, and the user is not affected, the fan is controlled to be kept in the original state without being rotated.
And S104, adjusting an air supply strategy of the fan according to the decibel value of the noise of the fan at each yaw angle, so that the decibel value of the noise emitted by the fan is smaller than or equal to a first preset decibel threshold value.
After the decibel value of the noise of each yaw angle of the fan is obtained, the air supply strategy of the fan is adjusted according to the decibel value of the noise of each yaw angle, so that the decibel value of the noise emitted by the fan is smaller than or equal to a first preset decibel threshold value. The air supply strategy comprises a working mode of the fan, an air supply gear and an air supply range, and the working mode comprises fixed-point air supply and sweeping air supply. The fan is controlled to supply air according to the decibel value of the noise of each yaw angle, so that the rotation efficiency of the fan can be effectively improved, and the noise emitted by the fan can be reduced.
In one embodiment, as shown in fig. 3, step S104 includes: substeps S1041 to substep S1043.
And a substep S1041 of determining a target rotation range of the fan according to the decibel value of the noise of the fan at each yaw angle.
Specifically, the decibel value of the noise of the fan at each yaw angle is respectively compared with a second preset decibel threshold value; and acquiring a yaw angle corresponding to the decibel value smaller than the second preset decibel threshold value, and determining the target rotation range of the fan. Here, the target rotation range is a range of an angle by which the fan rotates, and for example, the target rotation range is [30 °,50 ° ]. It should be noted that the second preset decibel threshold may be set according to specific situations, which is not specifically limited in this application, and optionally, the second preset decibel threshold is 70 decibels, and it can be understood that the second preset decibel threshold may also be greater than or equal to the first preset decibel threshold.
Illustratively, if the yaw angle of the fan is in the range of [30 °,150 ° ], the decibel value of the noise of the fan from 30 ° to 60 ° is smaller than the decibel value of the second preset decibel threshold, and the decibel value of the noise of the fan from 60 ° to 150 ° is greater than or equal to the decibel value of the second preset decibel threshold, the target rotation range of the fan can be determined to be [30 °,60 ° ].
The target rotational ranges of the fans may be two or more, and for example, the target rotational ranges of the fans may be [30 °,50 ° ] and [120 °,140 ° ].
And a substep S1042 of determining an air supply strategy of the fan according to the target rotation range.
After the target rotation range is determined, the air supply strategy of the fan can be determined according to the target rotation range. The air supply strategy of the fan comprises the working mode, the air supply range, the air supply gear and the like of the fan. Specifically, a working mode and an air supply gear before fan blades are abnormal are determined, and an air supply strategy of the fan is determined again according to the working mode, the air supply gear and a target rotation range.
In an embodiment, a specific method for determining an air supply strategy of a fan includes: acquiring position information of a user, and judging whether the position information is positioned in a target rotation range; if the position information is located in the target rotation range, determining an air supply strategy of the fan according to the position information and the target rotation range; and if the position information is not in the target rotation range, determining the air supply strategy of the fan as the fan closing. It should be noted that, the position information of the user may be obtained through a portable device or an indoor positioning device, and the position coordinates of the user may also be obtained through a camera mounted on the fan, which is not limited in this application.
Further, after the position information of the user is obtained, the blowing range of the fan is determined based on the target rotation range, and whether the position information is located in the blowing range of the fan is judged; if the position information is located in the blowing range of the fan, determining the air supply strategy of the fan according to the position information and the blowing range; and if the position information is not located in the blowing range of the fan, determining the air supply strategy of the fan as the fan turning off.
The blowing range of the fan is the range which can be covered by wind power when the fan blows in the target rotating range. It can be understood that the range covered by the blowing range of the fan comprises a target rotating range and reserved angles preset on two sides of the target rotating range, the reserved angles are angles outside the target rotating range and capable of blowing to the blowing range, and the reserved angles can be set according to actual conditions. And if the position information of the user is located in the blowing range of the fan, re-determining the blowing range of the fan, and determining the blowing strategy of the fan according to the working mode before the adjustment of the fan, the blowing gear and the re-determined target rotation range of the fan. By determining the blowing range of the fan and the position information of the user, the intelligence of the fan is improved, and the user experience is improved.
In an embodiment, a specific manner of determining whether the position information of the user is located in the blowing range of the fan is as follows: acquiring position information of a fan, and establishing a coordinate system by taking the position information of the fan as an origin; marking the blowing range of the fan in the coordinate system to obtain a target blowing area; and acquiring the position coordinates of the user in the coordinate system through the wearable device, and judging whether the position coordinates are located in the target blowing area. The coordinate system may be a two-dimensional coordinate system or a three-dimensional coordinate system, and the present application is not particularly limited. The position information of the fan may be obtained through wireless communication or base station positioning, or may be obtained by a positioning device (e.g. GPS) carried by the fan, and the present application is not limited specifically. And when the position coordinates of the user are positioned in a target blowing area, taking the target blowing area as a blowing range, and determining the blowing strategy of the fan according to the working mode before the fan is adjusted, the blowing gear and the blowing range.
And a substep S1043 of supplying air according to the air supply strategy, so that the decibel value of the noise emitted by the fan is smaller than or equal to a first preset decibel threshold value.
And air supply is carried out according to an air supply strategy, so that the decibel value of the noise emitted by the fan is smaller than or equal to a first preset decibel threshold value. It should be noted that, if the user is not located within the blowing range of the fan, which indicates that the fan is not beneficial to be started, the fan is controlled to be turned off; and if the user is positioned in the blowing range of the fan, controlling the fan to blow air according to the working mode, the air blowing gear and the blowing range in the air blowing strategy, so that the decibel value of the noise emitted by the fan is smaller than or equal to a second preset decibel threshold value. The second preset decibel threshold may be set according to specific situations, which is not specifically limited in the present application, and optionally, the second preset decibel threshold is 70 decibels.
The fan control method provided by the embodiment detects whether the fan suffers external interference by monitoring whether the rotation of the fan blades of the fan is abnormal, if the rotation of the fan blades is abnormal, the decibel value of the noise emitted by the fan is acquired, whether the decibel value is greater than a first preset decibel threshold value is judged, whether the noise emitted by the fan is large can be determined, when the decibel value is greater than the first preset decibel threshold value, the fan is controlled to rotate along the horizontal direction, the decibel value of the noise of the fan at each yaw angle is recorded, and then the air supply strategy of the fan is adjusted according to the decibel value of the noise of the fan at each yaw angle, so that the decibel value of the noise emitted by the fan is smaller than or equal to the first preset decibel threshold value.
