Example 1
According to an embodiment of the present invention, there is provided an embodiment of a method of controlling a fan, it being noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order different from that herein.
Fig. 1 is a flowchart of a control method of a fan according to an embodiment of the present invention, as shown in fig. 1, the method includes the steps of:
step S102, obtaining image information of an air supply area of the fan.
Specifically, the image acquisition device can be arranged at the head of the fan to acquire the image information of the air supply area of the fan, and the air supply area is continuously changed when the fan swings, so that the image information acquired by the image acquisition device can also be changed according to the change of the air supply area. The period for the image acquisition device to acquire the image can be preset, so that the image acquisition device acquires the image information of the current air supply area according to the period.
Step S104, determining whether the image information contains a target object or not based on a first model, and acquiring first attribute information of the target object in the image when the image information contains the target object, wherein the first model is obtained through machine learning training according to a plurality of first sample data, and the first sample data comprises: the image information and a label corresponding to the image information are used for indicating whether the image information contains a target object and first attribute information of the target object contained in the image information.
Specifically, the target object may be any user, or may be a target object specified by a user, for example: the first attribute information may be used to characterize the type of the target object, i.e. to determine whether the target object is a user or a target object.
In an alternative embodiment, a plurality of first sample data may be provided for machine learning as follows: image information of the target object and its tag, including the first attribute information, are not included. And (3) sending the sample data into an initial empty model for learning, so that the model has the capability of judging the first attribute information of the target object in the image information, then using test data to test the obtained model obtained through learning, and determining that the model obtained through training can be used for determining the first attribute information of the target object in the image information under the condition that the test is successful.
Step S106, if the air supply area of the fan reaches the area where the target object is located, the fan is controlled to adjust the operation parameters to the operation parameters corresponding to the first attribute information of the target object.
Specifically, the operation parameters of the fan may include: the wind swinging speed and/or the rotating speed of the fan blades, wherein the wind swinging speed is used for representing the rotating speed of the head of the fan in the wind swinging process, the rotating speed of the fan blades is used for controlling the air output of the fan, and the larger the rotating speed of the fan blades is, the larger the air output of the fan is.
In the above steps, the different first attribute information corresponds to different operation parameters of the fan, and the operation parameters corresponding to the first attribute information may be preset in a processor of the fan, or may be set manually.
As can be seen from the above, in the embodiments of the present application, the image information of the air supply area of the fan is obtained, whether the image information includes the target object is determined based on the first model, and if the image information includes the target object, the first attribute information of the target object in the image is obtained, and if the air supply area of the fan reaches the area where the target object is located, the fan is controlled to adjust the operation parameter to the operation parameter corresponding to the first attribute information of the target object. According to the technical scheme, the first attribute information of the target object is determined by identifying the image information of the air supply area of the fan, so that the operation parameters of the fan are adjusted according to the first attribute information of the target object, corresponding services can be accurately provided for various different target objects in the air supply area of the fan, and the technical problem that the intelligent degree of the fan in the prior art is low is solved.
Optionally, according to the above embodiment of the present application, after acquiring the image information of the air supply area of the fan, the method further includes: and under the condition that the image information does not comprise the target object, the wind swinging speed of the fan is increased.
Specifically, under the condition that the image information does not include the target object, it can be determined that the air supply area of the fan has no air supply requirement, so that in order to reduce the energy consumption of the fan, under the condition that the image information does not include the target object, the air supply speed of the fan is increased, so that the fan can perform air supply for the area with the air supply requirement.
Optionally, according to the above embodiment of the present application, the first attribute information of the target object includes a type of the target object, where the type includes a control main body and the target object, and when an air supply area of the fan reaches an area where the target object is located, the control fan adjusts an operation parameter to an operation parameter corresponding to the first attribute information of the target object, including:
in step S1061, in the case where the type of the target object is the control subject, second attribute information of the control subject is acquired, and the operation parameters of the fan are adjusted according to the second attribute information.
Specifically, the control body may be a user, and the second attribute information of the control body may include information of age, temperature, sex, distance from the fan, and the like of the control body.
In step S1063, if the type of the target object is the target object, the fan speed is increased and/or the fan blade speed is decreased.
Specifically, the target object may be an object selected by the control main body, for example, a user may select hot food, and when the air supply area reaches the hot food area, the air swing speed of the fan is increased so as to quickly leave the hot food area, or the rotation speed of the fan blade is reduced so as to reduce the air supply quantity of the fan to the hot food area.
Further, the fan may be preset with a model for identifying the dining state of the control body, so that the operation parameters of the fan are controlled according to the dining state of the control body.
Optionally, according to the above embodiment of the present application, obtaining second attribute information of the control main body, and adjusting an operation parameter of the fan according to the second attribute information includes:
step S10611, acquires the temperature of the control subject in the second attribute information.
In step S10613, when the temperature of the control main body is lower than the preset temperature threshold, and the air supply area of the fan reaches the area where the control main body is located, the fan is controlled to increase the air swing speed of the fan and/or reduce the fan blade rotation speed.
In an alternative embodiment, the temperature of the user may be detected by the temperature sensor, and because the temperature of each user may be different from each other due to the fact that the temperature of each user in the same environment is different from each other, the above scheme reduces the rotation speed of the fan or accelerates the wind swinging speed when the temperature of the user is lower than the preset temperature, so as to reduce the wind output of the user with lower temperature.
Optionally, according to the above embodiment of the present application, obtaining second attribute information of the control main body, and adjusting an operation parameter of the fan according to the second attribute information includes:
step S10615, obtaining the age of the control subject in the second attribute information based on a second model, where the second model is obtained by machine learning training according to a plurality of second sample data, and the second sample data includes: image information of a control subject and a tag for indicating an age of the control subject in the image information.
In the above step, age information of the control subject is determined based on the second model, and in an alternative embodiment, the second sample data may include: the image information of the control subject of each age group is contained, and the label used for indicating the age of the control subject is used for training the initial model by using the second sample data to obtain a second model, so that the accuracy of the second model for identifying the age of the control subject is higher than the preset accuracy.
In step S10617, in the case where the age of the target object is less than the preset age threshold, the distance from the control subject to the fan in the second attribute information is detected.
Specifically, in the above steps, the distance between the target object and the fan may be detected by means of infrared human body induction.
In step S10619, when the distance is smaller than the preset distance, the fan is controlled to be locked.
In an alternative embodiment, the preset age threshold is set to 10 years old, the preset distance is set to 0.3 meter, and in the case that the age of the target object is determined to be less than 10 years old and the distance from the fan is less than 0.3 meter through image information identification, in order to prevent danger caused by the child being too close to the fan, the fan is controlled to be locked to stop running.
Optionally, according to the above embodiment of the present application, obtaining second attribute information of the control main body, and adjusting an operation parameter of the fan according to the second attribute information includes:
step S10621, obtaining the gender of the control subject in the second attribute information based on a third model, where the third model is obtained by machine learning training according to a plurality of third sample data, and the third sample data includes: image information of a control subject and a tag for indicating the sex of the control subject in the image information;
in step S10623, when the sex of the control body is female, and the air supply area of the fan reaches the area where the control body is located, the fan is controlled to increase the air-swinging speed of the fan and/or reduce the rotation speed of the blades.
In the same temperature environment, women generally have lower air supply requirements than men, so when the control main body is identified as women, the air output to women is reduced by increasing the swing air speed and/or reducing the fan blade rotating speed, so that both men and women using the same fan can feel comfortable.
Optionally, according to the above embodiment of the present application, while controlling the fan to adjust an operation parameter to an operation parameter corresponding to the first attribute information of the target object, the method further includes:
step S108, detecting a control instruction of the control subject.
In the control process of the fan, the control instruction of the control main body is detected in real time, and as an alternative embodiment, the control instruction of the detection target object may include: detecting the received voice information, and determining whether the voice information comprises a control instruction or not by analyzing the voice information; or detecting a control instruction sent by an external communication device of the fan. For example, control instructions may be issued to the fan by a mobile terminal in communication with the fan.
In step S1010, when a control instruction of the control main body is detected, the fan is controlled according to the control instruction.
In the above step, when the control instruction of the control main body is detected, the fan is controlled according to the control instruction, so that the control instruction of the control main body has the highest control priority, and the fan is controlled by the user instruction under the condition that the intelligent control of the fan cannot meet the user demand, thereby further improving the comfort level of the user.
Further, under the condition that a control instruction is not detected, the fan is kept to be controlled to adjust the operation parameters to the operation parameters corresponding to the first attribute information of the target object.
In an alternative embodiment, the user a is a female, and when the fan swings to reach the area where the user a is located, the rotation speed of the fan blade is reduced or the swing wind speed is increased according to the identification result, but the requirement of the user a on the air output of the fan is greater, so that the user a can change the rotation speed of the fan blade or the swing wind speed of the fan by sending a control instruction to the fan, and the user a can feel more comfortable.
The intelligent control method for the fan is suitable for the situation that the intelligent control result of the fan is not matched with the air quantity required by the user, and the control method for the fan provided by the embodiment of the application can not only simultaneously meet the requirements of a plurality of users in the same environment, but also meet the independent requirements of the users, so that the users have higher comfort level.
Fig. 2 is a schematic diagram of an alternative method for controlling a fan according to an embodiment of the present application, and in conjunction with fig. 2, the fan performs air supply according to a gear selected by a user after starting operation, and at the same time, obtains image information of an air supply area of the fan, determines first attribute information of a target object, that is, a type of the target object, by using the identified image information, and controls the fan according to whether the first attribute information of the target object is the target object or a control body, so as to adjust an actual air output of the fan by changing a wind swinging speed and a fan blade rotation speed of the fan. When the target object is a target object, the operation parameters of the fan are adjusted according to the operation parameters corresponding to the preset object. When the first attribute information of the target object is the control main body, the age of the control main body is analyzed through image information analysis, the distance between the control main body with the age smaller than a preset value and the fan is determined through infrared human body induction, when the age of the control main body is smaller than the preset value, the control main body is determined to be a child, and when the detected distance between the child and the fan is smaller than the preset distance, the fan is turned off, so that the child is protected. Meanwhile, the gear of the fan can be wirelessly controlled according to terminal equipment communicated with the fan through a wireless network, so that the actual air supply quantity of the fan can be adjusted.
