Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a fan control method according to an embodiment of the present disclosure. The fan control method may include steps S101 to S104, and the like, and specifically may be as follows:
s101, acquiring an image containing clothes.
The clothing may include clothing, socks, towels or other objects to be aired, images of the clothing may be acquired by an image acquisition device such as a camera or a camera preset in the clothing airing area, the clothing may include one or more pieces of clothing, the setting position, type, shooting angle, or the like of the image acquisition device may be flexibly set according to actual needs, specific content is not limited herein, for example, the image including the clothing may be as shown in fig. 2.
In some embodiments, acquiring an image containing clothing may include: detecting whether the clothes are dry or not after the clothes are aired for a preset time; and if the clothes are not dry, acquiring an image containing the clothes through the camera.
In order to achieve that the fan is started to assist the clothes to be dried as soon as possible under the condition that the clothes are not dried after the clothes are aired for the preset time, so as to improve convenience and flexibility of fan control, specifically, a timer can be started to start timing when the clothes are aired, and after the timer times the preset time, the clothes are aired for the preset time, and whether the clothes are dried or not can be detected. The preset time can be flexibly set according to actual needs, for example, the preset time can be set by a user or a default time.
In some embodiments, detecting whether the laundry is dry may include: acquiring the current weight of the clothes and the corresponding reference weight when the clothes are dried; if the current weight is greater than the reference weight, determining that the clothes are not dried; and if the current weight is less than or equal to the reference weight, determining that the laundry is dried.
In order to improve the accuracy of the laundry drying detection, whether the laundry is dried may be determined by the weight of the laundry. Specifically, when the laundry is in a dry state, the weight of the laundry may be detected in advance by an electronic scale or gravity sensing or the like, a reference weight may be obtained, and the reference weight may be stored. And acquiring the current weight of the clothes aired currently through a preset gravity sensor on the clothes airing rod or the clothes hanger, comparing the current weight with a pre-stored reference weight, and judging whether the current weight of the clothes is greater than the reference weight. If the current weight is greater than the reference weight, determining that the clothes are not dried; and if the current weight is less than or equal to the reference weight, determining that the laundry is dried.
It should be noted that when a plurality of pieces of clothes are included, the current weight of each piece of clothes may be compared with the corresponding reference weight, or the current weight of each piece of clothes is summed to obtain the total weight, and the reference weight of each piece of clothes is summed to obtain the total reference weight, and then the total weight is compared with the total reference weight, and if the total weight is greater than the total reference weight, it is determined that the clothes are not dried; if the total weight is less than or equal to the total reference weight, it is determined that the laundry is dried.
In some embodiments, detecting whether the laundry is dry may include: acquiring current images of all surfaces of clothes, and acquiring corresponding reference images when the clothes are dry; if the pixels of the current image and the reference image are not matched, determining that the clothes are not dried; and if the pixels of the current image and the reference image are matched, determining that the clothes are dry.
In order to improve the convenience of the clothes drying detection, whether the clothes are dried or not can be determined through pixel comparison of the image. Specifically, when the clothes are in a dry state, images including respective surfaces of the clothes may be captured in advance from different shooting angles by an image capturing apparatus such as a camera or a camera, a reference image may be obtained, and the reference image may be stored.
Then, images including the surfaces of the clothes can be acquired from different shooting angles through one or more image acquisition devices preset in the clothes drying area, so that a plurality of current images are obtained, and the current images at the corresponding shooting angles are compared with the reference image, for example, the current image of the front of the clothes a is compared with the reference image of the front of the clothes a. And judging whether the pixels of the current image and the reference image are matched, wherein the color of the clothes in a wet state is different from the color of the clothes in a dry state, if the pixels of the current image and the reference image are not matched, the clothes are determined not to be dry, and if the pixels of the current image and the reference image are matched, the clothes are determined to be dry. The pixel matching can be the pixel value of the clothes in the current image, the difference value between the pixel value of the clothes in the current image and the pixel value of the clothes in the reference image is smaller than a preset threshold value, and the preset threshold value can be flexibly set according to actual needs.
In some embodiments, acquiring an image containing clothing may include: when detecting that clothes exist in the clothes airing area, acquiring images containing the clothes through the camera.
In order to realize that when the clothes start to be dried, the fan is started to assist the clothes to be dried as soon as possible, so that the reliability of fan control is improved. Specifically, images in a clothes drying area can be acquired through image acquisition equipment such as a preset camera in the clothes drying area to obtain an initial image, whether clothes exist in the clothes drying area is detected based on the initial image, when the clothes exist in the clothes drying area is detected, images containing the clothes are acquired through the camera, and when the clothes do not exist in the clothes drying area, the images containing the clothes cannot be acquired.
S102, identifying a wetting area of the clothes according to the image to obtain a distribution map of the wetting area.
In some embodiments, identifying a wet area of the garment from the image, and obtaining a profile of the wet area may include: acquiring a corresponding reference image when the clothes are dry; comparing the pixel value of the image with that of the reference image to obtain pixel difference; and determining the moisture area of the clothes according to the pixel difference to obtain a distribution map of the moisture area.
In order to improve the accuracy of the identification of the moisture area of the laundry, the moisture area of the laundry may be determined based on a pixel difference of the laundry in the image. For example, a pre-stored reference image corresponding to the drying of the clothes may be acquired, and then the acquired image of the clothes is compared with the reference image by using the pixel value, that is, the pixel value of the area where the clothes are located in the image of the clothes is compared with the pixel value of the area where the clothes are located in the reference image, so as to obtain the pixel difference. Since the pixel value of the laundry in the wet state is different from the pixel value of the laundry in the dry state, the wetting area of the laundry can be determined according to the pixel difference of the laundry between the image of the laundry and the reference image, so that the distribution map of the wetting area can be obtained.
In some embodiments, identifying a wet area of the garment from the image, and obtaining a profile of the wet area may include: and identifying the moisture area of the clothes in the image through a preset identification model to obtain a distribution map of the moisture area.
In order to improve the accuracy of identifying the wet area of the clothes, the wet area of the clothes in the image can be identified through the identification model, for example, the wet area of the clothes in the image can be identified through a preset identification model, and a distribution map of the wet area is obtained. The type of the recognition model can be flexibly set according to actual needs, the recognition model can be a target detection model SSD or YOLOv3, and the recognition model can also be a convolutional neural network CNN or R-CNN. The recognition model can be trained through a plurality of sample images containing clothes of different damp types to obtain a trained recognition model, and the preset recognition model is the trained recognition model.
And S103, determining the air supply range of the fan according to the distribution map.
After the distribution map of the wet area of the laundry is obtained, in order to allow the fan to blow air in alignment with the wet area of the laundry, the blowing range of the fan may be determined based on the distribution map of the wet area.
In some embodiments, determining the blowing range of the fan according to the profile may include: determining discrete regions of the distribution of the wet regions from the profile; determining a circumscribed polygon of the discrete region; and determining the air supply edges of the fan in a plurality of different directions according to the circumscribed polygon to obtain an air supply range.
In order to improve the accuracy of determining the air supply range so that the fan can blow to all the wet areas of the clothes, as shown in fig. 3, firstly, discrete areas of the distribution of the wet areas can be determined according to a distribution diagram, the discrete areas can include one or more discrete areas, then, the rightmost edge wet point, the leftmost edge wet point, the uppermost edge wet point and the lowermost edge wet point in the discrete areas can be detected, and the circumscribed polygon of the discrete areas can be determined according to the points of the various edges, the number of the edges of the circumscribed polygon can be flexibly set according to actual needs, for example, the circumscribed polygon can be a sector or a quadrangle, and at the moment, the air supply edges of the fan in different directions such as up, down, left and right and the like can be determined according to the circumscribed polygon, so as to obtain the air supply range. The type of the fan can be flexibly set according to actual needs, for example, the fan can be a circulating fan or the like.
In some embodiments, determining the blowing range of the fan according to the profile may include: and displaying the distribution diagram, and receiving the air supply range input by the user based on the displayed distribution diagram.
In order to improve the flexibility of determining the air supply range, the fan can blow to the wet area of the clothes according to the requirements of the user, after the distribution diagram of the wet area of the clothes is obtained, the distribution diagram can be sent to a mobile terminal such as a mobile phone used by the user for displaying, or the distribution diagram can be displayed in a display screen preset by the fan for the user to check. Then, an air blowing range input by the user based on the displayed profile may be received, for example, a sliding operation performed by the user within the displayed profile may be received to form the air blowing range based on a sliding trajectory generated by the sliding operation. Or the click operation of a plurality of different positions executed by the user in the displayed distribution diagram can be received, so that a circumscribed polygon of the discrete region is determined according to each click position based on the plurality of click positions generated by the click operation, the number of sides of the circumscribed polygon can be flexibly set according to actual needs, for example, the circumscribed polygon can be a sector or a quadrangle, and at the moment, the air supply edges of the fan in a plurality of different directions such as up, down, left and right can be determined according to the circumscribed polygon, and the air supply range can be obtained. Alternatively, a plurality of candidate air blowing ranges may be displayed in the distribution map for selection by the user, and a selection instruction from the user may be received, one of the plurality of candidate air blowing ranges being selected based on the selection instruction.
And S104, controlling the fan to operate according to the air supply range.
After the air supply range of the fan is determined, the swing angle of the fan can be determined based on the air supply range, and the fan is controlled to supply air according to the swing angle, so that the fan can supply air into the air supply range. The number of the fans may be one or more, for example, as shown in fig. 4, and the number of the fans may be one, for example, as shown in fig. 5. In the running process of the fan, the time required by drying the clothes can be acquired in real time, the time is dynamically output in a voice broadcasting or display screen displaying mode, or the time is sent to a mobile phone or a terminal such as an intelligent sound box, so that the terminal dynamically outputs the time in a voice broadcasting or display screen displaying mode, and a user can check the time conveniently.
In some embodiments, controlling the fan operation according to the blowing range may include: acquiring the humidity grade of the clothes; determining the air volume and/or the air temperature of the fan according to the humidity level; and controlling the fan to operate according to the air supply range, the air quantity and/or the air temperature.
In order to enable the fan to flexibly and adaptively operate according to the proper operation parameters according to the actual condition that the clothes are wet, and improve the drying efficiency of the clothes, the moisture level of the clothes can be obtained, for example, because the pixel values of the clothes under different moisture levels are different, the pixel values of the clothes can be detected based on the image of the clothes, and the moisture level of the clothes can be determined according to the pixel values. For another example, since the weights of the laundry under different moisture levels are different, the weight of the laundry may be detected, and the moisture level of the laundry may be determined according to the weight of the laundry. Then, a mapping relation between different humidity levels and the air volume of the fan or the temperature of the air and the like may be obtained, and the air volume of the fan and/or the temperature of the air corresponding to the humidity level may be determined according to the mapping relation, for example, the more humid the laundry is, the larger the air volume of the fan, the higher the temperature of the air supplied by the fan (which may also be determined in combination with the type of the laundry) and the like, at which time the operation of the fan may be controlled according to the air supply range, the air volume and/or the temperature of the air.
It should be noted that the type of the clothes can also be obtained, the air volume and/or the air temperature of the fan can be determined according to the humidity level, the type of the clothes and the like, and the operation of the fan can be controlled according to the air supply range, the air volume and/or the air temperature.
In some embodiments, after controlling the operation of the fan according to the blowing range, the fan control method further includes: acquiring the time length required by air drying of clothes, and displaying the time length; receiving an adjusting instruction input by a user based on the displayed duration; and adjusting the operating parameters of the fan according to the adjusting instruction, and controlling the fan to operate according to the adjusted operating parameters.
In order to improve the efficiency of drying the laundry and to improve the flexibility of controlling the fan, the operating parameters of the fan may be dynamically adjusted. Specifically, the time length required for drying the clothes may be obtained, for example, the current air quantity of the fan, the current temperature of the fan, and other operation parameters may be obtained, the current humidity level of the clothes may be obtained, and weather information of the environment where the clothes are located, where the weather information may include the air quantity, the air temperature, the air humidity, and the like of natural air, and then the time length required for drying the clothes may be determined according to the current humidity level of the clothes, the current operation parameters of the fan, the weather information, and the like. After the required time length for drying the clothes is obtained, the time length can be displayed through a display screen preset by a fan, or the time length is sent to terminals such as a mobile phone for display, so that a user can check the time length conveniently.
At this time, an adjustment instruction input by the user may be received based on the displayed duration, where the adjustment instruction may be input by a physical button or a virtual button corresponding to an operation parameter, such as an air volume, a temperature, or a shaking direction (i.e., a shaking angle), preset by the user through the fan, or, as shown in fig. 6, the adjustment instruction may be generated and sent to the fan after the user sets the operation parameter of the fan through a setting interface of a terminal, such as a mobile phone, and finally, the operation parameter, such as the air volume, the temperature, or the shaking direction, of the fan may be adjusted according to the adjustment instruction, and the fan is controlled to operate according to the adjusted operation parameter.
In some embodiments, obtaining the length of time required for the laundry to dry may include: detecting the weight of the laundry during the operation of the fan; acquiring current environmental parameters of an environment where clothes are aired, and acquiring reference weight and clothes types when the clothes are dried; acquiring a difference between the weight of the laundry and a reference weight; and determining the time length required by the air drying of the clothes according to the difference, the current environmental parameters and the clothes category.
In order to improve the accuracy of determining the time length required for drying the clothes, the current weight of the clothes can be detected through a preset gravity sensor on the clothes hanger or the clothes rod, and the current environmental parameters of the environment where the clothes are dried can be obtained, wherein the current environmental parameters can include the air volume, the air temperature, the air humidity and the like of natural air, and the reference weight and the clothes type (namely the type of the clothes) when the clothes are dried can be obtained, and the clothes type can include the material, the style and the like of the clothes. The difference between the weight of the laundry and the reference weight, which represents the degree of wetness (i.e., the wetness level) of the laundry, may then be obtained, at which point the length of time required for the laundry to dry may be determined based on the difference, the current environmental parameters, and the laundry category.
In some embodiments, the fan control method further comprises: when the laundry has been dried, the fan is turned off.
In order to improve the intelligence and convenience of the fan control, whether the clothes are dry or not may be detected in real time or at preset time intervals during the operation of the fan, for example, whether the clothes are dry or not may be determined by comparing pixels of an image of the clothes, or whether the clothes are dry or not may be determined by the weight of the clothes, etc. When the clothes are not dried, the opening state of the fan is maintained; when the laundry has been dried, the fan is turned off.
In some embodiments, the fan control method further comprises: and detecting whether the fan supplies air against natural wind or not, and closing the fan when the fan supplies air against the natural wind.
For example, as shown in fig. 7, in order to avoid energy waste due to the failure of the fan to supply air to the clothes when the fan supplies air against the natural wind, it may be detected whether the fan supplies air against the natural wind in real time or at preset intervals during the operation of the fan, for example, whether the blades of the fan are subjected to the resistance of the natural wind, or the wind direction of the natural wind. When the fan is not blowing against the natural wind, the opening state of the fan is maintained; when the fan is blown against the natural wind, the fan is turned off.
In some embodiments, the fan control method further comprises: and detecting the air volume of the natural wind, and turning off the fan when the air volume of the natural wind is larger than a preset threshold value.
In order to avoid the problem that the fan cannot supply air to the clothes when large natural wind exists and waste energy, the air quantity of the natural wind in the environment where the clothes are located can be detected in real time or at preset time intervals in the operation process of the fan, for example, the air quantity of the natural wind can be detected through an air speed detector and the like. When the air volume of the natural wind is smaller than a preset threshold value, the opening state of the fan is maintained; when the air quantity of the natural wind is larger than a preset threshold value, the effect of the fan on accelerating the drying of the clothes is small, the fan is turned off, and the preset threshold value can be flexibly set according to actual needs.
According to the embodiment of the application, the image containing the clothes can be obtained, the wetting area of the clothes is identified according to the image, and the distribution map of the wetting area is obtained; the air supply range of the fan can be determined according to the distribution diagram, and the operation of the fan can be controlled according to the air supply range. The fan can accurately supply air to the wet area of the clothes, so that the clothes drying efficiency is improved, and the flexibility of fan control is improved.
