Fig. 1 schematically shows a flow chart of a fan control method according to an embodiment of the present invention. Referring to fig. 1, the fan control method provided in the embodiment of the present invention specifically includes steps S11 to S13, as follows:
and S11, detecting the target facial features of the user in the preset wind sweeping area.
In the embodiment of the invention, a user previously networks a mobile device and a fan through WIFI, then enters human face characteristics through application software on the mobile device and sets the wind sweeping parameters matched with the human face characteristics according to the requirements of the user, and the fan receives and stores the human face characteristics of the user by using an internal storage medium. The left side and the right side of the fan are respectively provided with an image acquisition device and an image processing device which rotate together with the fan. The image acquisition device is used for acquiring image information in real time in the shaking process of the fan, and the image processing device is used for carrying out feature analysis on the image information acquired by the image acquisition device so as to identify facial features in the image information and analyze the shaking direction of the fan.
After the fan is turned on, a user can select whether to turn on the intelligent wind sweeping mode through key or gesture operation, the fan starts to work in the intelligent wind sweeping mode when the fan is turned on, the head shaking function is automatically turned on along with the fan, and the fan automatically exits the intelligent wind sweeping mode when the user turns off the head shaking function or turns off the fan.
In the embodiment of the invention, the area division is carried out on the wind sweeping range of the fan in advance, and when the fan starts to work in an intelligent wind sweeping mode, the target facial features of users in each preset wind sweeping area are detected through the image acquisition devices and the image processing devices which are arranged on the left side and the right side of the fan.
The target facial features are facial features of all users in the wind sweeping area, and may include a plurality of facial features or only one facial feature.
And S12, if the detected target facial features comprise the human face features in the preset human face authentication data, acquiring target wind sweeping parameters matched with the target facial features.
And S13, controlling the fan to sweep the wind area according to the obtained target wind sweeping parameters.
According to the fan control method provided by the embodiment of the invention, the corresponding wind sweeping parameters are matched for the users in the wind sweeping area through detecting the target facial features of the users in the wind sweeping area, and the wind sweeping area is swept according to the matched wind sweeping parameters, so that accurate air supply of different users is realized, the personalized air supply requirements of the users are met, and the user experience is effectively improved.
In the embodiment of the invention, if the target facial features of the user are not detected in the preset wind sweeping area or the detected target facial features do not contain the facial features in the human face authentication data, the fan is controlled to keep the current wind sweeping parameters to sweep the wind sweeping area so as to maintain the existing wind sweeping state.
In the embodiment of the present invention, as shown in fig. 2, the step S11 of detecting the target facial features of the user in the preset sweep area specifically includes steps S21 to S22, as follows:
s21, dividing a wind sweeping range of the fan into at least two continuous wind sweeping areas according to a preset identification angle along the oscillating direction of the fan;
and S22, sequentially detecting the target facial features of the users in each wind sweeping area in the wind sweeping process of the fan.
In this embodiment, in S21, the wind sweeping range of the fan is divided into at least two continuous wind sweeping areas according to the preset identification angle, and the specific implementation flow includes the following steps not shown in the drawings:
s31, taking the initial angle of the fan as the initial angle of the current wind sweeping area;
s32, calculating a rotation angle according to the rotation time of the fan and the corresponding rotation speed along the oscillating direction of the fan, and taking the rotation angle as the termination angle of the current wind sweeping area and the starting angle of the adjacent wind sweeping area when the rotation angle is equal to the identification angle;
and S33, detecting whether the oscillating direction of the fan changes, if the oscillating direction of the fan does not change, returning to the step S32, and if the oscillating direction of the fan changes, returning to the step S31.
Further, if it is detected that the oscillating direction of the fan has changed when the rotation angle is smaller than the recognition angle, the rotation angle is set as the end angle of the current wind sweeping area, and the process returns to step S31.
In this embodiment, after the intelligent sweeping mode is started, the step of setting the identification angle according to the actual use scene by the user is entered, and after the setting is completed, the fan starts to work in the intelligent sweeping mode and the shaking function is automatically started accordingly.
In one embodiment, when the fan works, the size of the wind sweeping area is determined according to the set identification angle, so that the wind sweeping range of the fan is divided into at least two continuous wind sweeping areas. In this example, the recognition angle is set to 60 °, and the oscillating fan in the 180 ° sweep range is described to divide the sweep region. The recognition angle is set to 60 °, and three windswept areas can be divided. Wherein 0-60 degrees is a first wind sweeping area; 60-120 degrees are second wind sweeping areas; and 120-180 degrees is a third wind sweeping area. The oscillating angle of the fan is calculated by a processor according to the formula: the rotation angle (°) is calculated as a rotation time(s) x rotation speed (°/s). The fan starting work processor synchronously calculates, the initial angle of the fan when the fan starts to work is the starting angle of the first wind sweeping area, when the fan works to the rotation time(s) x rotation speed (DEG/s) which is the identification angle, the position is the ending angle of the first wind sweeping area and the starting angle of the second wind sweeping area, and the rest of the subsequent areas are similar.
In this embodiment, whether the oscillating direction of the fan changes can be detected in the following manner, which specifically includes: acquiring first image information and/or second image information acquired in real time in the shaking process of the fan, wherein the first image information and the second image information are images respectively acquired by two image acquisition devices arranged at two sides of the fan; and performing characteristic analysis on the first image information and/or the second image information, and determining the shaking direction of the fan according to a characteristic analysis result.
Specifically, the fan collects facial features of users in each wind sweeping area through the assembled image collecting device, and meanwhile, the recognized facial features are sent to the controller to be compared with face authentication data stored in the fan. The two assembled image acquisition devices work in a switching mode according to the oscillating direction, when the fan oscillates from left to right, the image acquisition device on the right side works, and the image acquisition device on the left side is closed; when the fan shakes the head from right to left, the image acquisition device on the left side works, the image acquisition device on the right side is closed, so that the image information acquired in real time in the shaking process of the fan can be subjected to characteristic analysis to judge the shaking direction of the fan, when the shaking direction of the fan is changed, the rotation time of the fan is cleared, and each area is divided again according to the previous method.
In the embodiment of the present invention, the target facial features are facial features of all users in the sweep area, and may include a plurality of facial features or only one facial feature. Therefore, the acquiring the target wind sweeping parameter matched with the target facial feature specifically includes: when the target facial features comprise a plurality of faces, acquiring a wind sweeping parameter matched with each face feature, and optimizing each acquired wind sweeping parameter according to a preset parameter optimization rule to obtain the target wind sweeping parameter; and when the target facial features only comprise one face feature, acquiring a wind sweeping parameter matched with the face feature, and taking the acquired wind sweeping parameter as the target wind sweeping parameter.
In a specific embodiment, in the working process of the fan in the intelligent sweeping mode, when a plurality of facial features are recognized in a sweeping area and more than one facial feature can find the corresponding facial feature in the stored face authentication data, the sweeping parameters stored in the internal storage medium of each facial feature are called, the sweeping parameters are optimized by the controller according to a preset parameter optimization rule, and the target sweeping parameters are obtained through analysis and calculation; when only one facial feature is recognized in one wind sweeping area and the facial feature can find the corresponding facial feature in the stored face authentication data, the wind sweeping parameters stored in the internal storage medium of the facial feature are called and used as target wind sweeping parameters; when the facial features are not recognized in a wind sweeping area or the corresponding facial features are not found in the stored face authentication data, the existing wind sweeping state is continuously kept to sweep the wind for the area.
Further, the optimizing each acquired wind sweeping parameter according to a preset parameter optimization rule to obtain the target wind sweeping parameter specifically includes:
judging whether the wind sweeping parameters are the same or not;
if the wind sweeping parameters are the same as the target wind sweeping parameters, taking the wind sweeping parameters as the target wind sweeping parameters, otherwise, judging whether the wind sweeping parameters consistent with the lowest wind sweeping parameters in a preset wind sweeping parameter list exist in each wind sweeping parameter;
if the wind sweeping parameters consistent with the lowest wind sweeping parameters in a preset wind sweeping parameter list exist in the wind sweeping parameters, taking the lowest wind sweeping parameters as the target wind sweeping parameters, and otherwise, judging whether the wind sweeping parameters are all lower than preset standard wind sweeping parameters or all higher than the preset standard wind sweeping parameters;
if all the wind sweeping parameters are lower than or higher than the preset standard wind sweeping parameters, calculating a first mean value parameter of all the wind sweeping parameters, and taking the first mean value parameter as the target wind sweeping parameter, otherwise, calculating a second mean value parameter of all the wind sweeping parameters, and taking the wind sweeping parameters which are smaller than the second mean value parameter in the preset wind sweeping parameter list as the target wind sweeping parameters.
The taking the first mean value parameter as the target wind sweeping parameter specifically includes: judging whether the preset wind sweeping parameter list contains the first mean value parameter or not; if so, taking the first mean value parameter as the target wind sweeping parameter, otherwise, taking the wind sweeping parameter smaller than the first mean value parameter in the preset wind sweeping parameter list as the target wind sweeping parameter when each wind sweeping parameter is lower than a preset standard wind sweeping parameter, and taking the wind sweeping parameter larger than the first mean value parameter in the preset wind sweeping parameter list as the target wind sweeping parameter when each wind sweeping parameter is higher than the preset standard wind sweeping parameter.
In one embodiment, when a plurality of facial features are recognized in one wind sweeping area and more than one facial feature can find the corresponding facial feature in the stored face authentication data, the wind sweeping parameters stored in the internal storage medium of the user corresponding to each facial feature are called. The wind speed gears are used as wind sweeping parameters for explanation, the wind speed which can be selected from a preset wind sweeping parameter list is 10 gears, the wind speed which can be selected from a preset wind sweeping parameter list is 1 gear which is the lowest gear, and when a corresponding user selects the lowest gear in a certain area, the fan sweeps the wind in the area at the lowest gear rotating speed; when the gears of the fan selected by a user in a certain area are all less than or equal to a preset standard wind sweeping parameter, namely 5 gears, and no 1 gear exists, taking the average value of all the gears selected by the user in the area as a final rotating speed, and when the calculated average value does not correspond to an optional gear, taking the closest gear smaller than the average value as a working gear; when the fan gears selected by users in a certain area are all larger than or equal to 5 gears, taking the average value of all the user-selected gears in the area as the final rotating speed, and when the calculated average value does not correspond to the selectable gear, taking the closest gear larger than the average value as the working gear; when the gear of the fan selected by a user in a certain area is less than or greater than 5, taking the average value of all the user-selected gears in the area and subtracting one gear to be the final working gear, and when the calculated average value does not correspond to the selectable gear, taking the most similar gear less than the average value as the working gear; when the fan gear position selected by a user in a certain area is the same, the fan takes the gear position as the final working gear position.
According to the fan control method provided by the embodiment of the invention, the size of each wind sweeping area is determined in advance according to the identification angle set by a user, the wind sweeping area division is realized, then the user of each wind sweeping area is identified by using the image acquisition device and the image processing device, the relatively comfortable wind sweeping state of the user in the area is calculated according to the expected wind sweeping parameters preset by each user, the fan is controlled to accurately supply air to the area according to the calculated value, and the user experience is improved.
