Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The traditional fan mainly controls the switch, the rotating speed and whether the fan shakes head manually through a surface key or a knob, remote control or automatic control is difficult to realize, and the situation that people forget to adjust wind power or forget to close the fan after going out easily occurs, so that electric energy is wasted. In addition, the fan rotation speed corresponding to each gear button of the traditional fan is fixed, and cannot be adapted to the actual use requirements of users.
With the development of power electronics technology, intelligent fans are currently emerging. However, the existing intelligent fan mainly detects indoor temperature through a built-in temperature detector and a microcontroller, controls a switch and wind power according to detection results, and achieves an intelligent temperature control function based on ambient temperature. Part of products are provided with man-machine interaction module settings, and how the controller controls the fan at different temperatures can be adjusted. In addition, some products are also provided with wireless communication modules such as Bluetooth modules and the like, and can be in wireless communication with the mobile control terminal to realize indoor wireless control. Part of the intelligent fans also comprise various safety protection functions, intelligent lighting functions and the like.
The new generation intelligent fan still possess the function of communicating with wearable equipment, like an intelligent fan can obtain user's sleep state through wearing equipment such as bracelet, according to user's sleep state automatic adjustment blowout lets the wind of user's comfortable sleep, realizes the automatic control based on human state. In addition, the intelligent fan can recognize the gesture of a user through the sensor on the surface of the fan, and control and adjustment are carried out according to the gesture of the user, so that wireless control in a short distance is realized. As can be seen, researches on indoor environmental thermal comfort and human thermal comfort equations are increasingly and maturely developed, which makes it possible to implement intelligent speed control technology meeting the requirements of human thermal comfort.
Currently, fans generally perform rotational speed control by the following modes: (1) The fan rotating speed gear is controlled according to the time segment control mode, and different rotating speed gears can be freely selected according to different time segments; (2) The rotational speed gear of the fan is controlled according to the indoor temperature control mode, and the rotational speed of the fan is changed according to the detected indoor temperature change. However, the existing rotational speed control schemes still have some defects, such as that in the time-division control mode, the fan speed in the same time period is still constant, and the more diversified requirements cannot be met; in the indoor temperature control mode, the indoor temperature and the human body perceived temperature are different, so that the fan speed is kept unchanged within a certain period of time, the flexibility is not high, and the matching degree of the fan rotating speed and the human body requirement is not high.
Based on this, the embodiment of the application provides a rotational speed control method, which may include: obtaining a heart rate value of a user; calculating the heart rate value based on a preset formula and adjustable parameters to obtain a target fan rotating speed corresponding to the heart rate value; controlling the fan to perform rotation speed adjustment based on the obtained target rotation speed of the fan; thus, the fan is controlled according to the heartbeat speed of a human body, and the change can be carried out on smaller time granularity, so that the problem of fixed gear of the traditional fan is solved, and the problem of constant rotation speed in the same time period in a time segment control mode is solved; meanwhile, the heart rate of the human body can reflect the perception state of the human body to the environment in real time, so that the problem of the difference between the indoor temperature and the human body perception temperature in the indoor temperature control mode can be avoided, and the human body requirements can be better matched; in addition, the user can adjust the corresponding relation between the fan rotating speed and the heartbeat speed through the adjustable parameters, so as to provide differentiated control for the user and meet the requirements of different users.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
In an embodiment of the present application, referring to fig. 1, a flow chart of a rotational speed control method provided in an embodiment of the present application is shown, as shown in fig. 1, the method may include:
s101: obtaining a heart rate value of a user;
the heart rate refers to the number of beats per minute in a normal person in a calm state, which is also called a calm heart rate, and is generally 60 to 100 beats per minute, and may vary from one person to another depending on age, sex, or other physiological factors. Generally, the older the age, the faster the heart rate, the slower the elderly heart rate than the young, and the faster the female heart rate than the same age men, all of which are normal physiological phenomena. In a resting state, the normal heart rate of an adult is 60 to 100 times/min, and the ideal heart rate is 55 to 70 times/min (the heart rate of an athlete is slower than that of a common adult, and is generally about 50 times/min). Generally, when the temperature of the human body is too high, the heart rate of the human body is high, and when the temperature of the human body is too low, the heart rate of the human body is low, namely the heart rate value of the human body represents the state of the human body. In this embodiment of the present application, the fan is controlled based on the heart rate of the human body, so that the heart rate value of the user needs to be obtained in the first step.
It should be further noted that, the heart rate value of the user is obtained by the heart rate monitoring device, the heart rate monitoring device is independent of the fan body, the specific implementation forms are various, and most commonly, the wearable device such as a bracelet or the like is used, but the fan is not required to be independently provided with the heart rate monitoring device, and the fan can be directly connected with the existing heart rate monitoring device in a wireless manner, such as bluetooth, wireless local area network (Wireless Fidelity, wiFi) connection or the like, so that the heart rate value of the user is obtained by using the existing heart rate monitoring device. In this case, the fan may be connected to the heart rate monitor device and acquire the heart rate value of the user acquired by the heart rate monitor device.
It should be noted that, three methods for obtaining heart rate values are mainly used: firstly, extracting from electrocardiosignals; secondly, calculating a heart rate value from fluctuation detected by a pressure sensor when measuring blood pressure; thirdly, a photoelectric volumetric method. The former two methods can limit the activity of the detected object, and if the method is used for a long time, the physiological or psychological discomfort can be increased, and the photoelectric volumetric method measurement method is used for detecting, so that the wearing is convenient and the reliability is high. The basic principle of the photoelectric volumetric method is to utilize the difference of light transmittance caused by human tissue when blood vessels beat to measure heart beat, and the sensor used by the method consists of a light source and a photoelectric transducer, and is fixed on fingers or earlobes through binding bands, clamps and other methods. The light source generally adopts a certain wavelength selective to oxygen and hemoglobin in arterial blood Is provided. When the light speed passes through the blood vessel outside the human body, the light transmittance of the light beam is changed due to the change of the arterial pulse congestion volume, and the light reflected by the human tissue is received by the photoelectric converter, converted into an electric signal and converted into an electric signalAmplifying and outputting. Since the heart beat is a signal periodically varying with the pulsation of the heart, the arterial blood vessel volume also periodically varies, and thus the period of the electrical signal variation of the photoelectric transducer is the heart beat rate. Of course, it is within the scope of the present application if the heart beat rate is measured by other methods.
Step S101 may be performed periodically, so in some embodiments, step S101 may specifically include:
based on a preset time interval, the heart rate value of the user is obtained through heart rate monitoring equipment.
It should be noted that, for the human body, the temperature is changed gradually, that is, the comfortable wind speed of the human body in a tiny time period is not changed too much, if the real-time heart rate value of the user is used for controlling the rotation speed of the fan every minute or even every second, too much processing amount is wasted, and the service life of the machine is reduced. Based on this, the process of acquiring the heart rate value of the user may be performed at regular intervals, such as every 5 minutes or every 10 minutes, i.e. at regular intervals. In addition, the preset time interval can be adjusted according to the user requirement, so that differentiated services are provided.
Further, in some embodiments, before step S101, the method may further include:
receiving a first user instruction, and presenting a mode selection interface based on the first user instruction; the mode selection interface comprises a general mode option and an advanced mode option, wherein the general mode is used for indicating to determine the corresponding standard fan rotating speed according to different gears, and the advanced mode is used for indicating to determine the target fan rotating speed according to the heart rate value of a user;
receiving a second user instruction, and judging whether a user selects an advanced mode option or not based on the second user instruction;
when the judgment result is that the user selects the advanced mode option, step S101 is performed.
It should be noted that, for convenience of use, the conventional speed control mode may still be reserved, that is, the speed control method in the embodiment of the present application may be used as an advanced mode for the user, and when the user selects a general mode, the speed control service of the fan may be provided to the user through conventional gear control, timing control or other control methods.
Further, when the determination results in the user selecting the advanced mode option, in some embodiments, the method further comprises:
Presenting an advanced mode interface comprising an adjustable parameter input box;
receiving a third user instruction, acquiring numbers input by a user in the adjustable parameter input box based on the third user instruction, and determining the acquired numbers as the adjustable parameters.
It should be noted that, since the adjustable parameter is changed according to the user's requirement, the advanced mode interface includes an input box for adjusting the adjustable parameter, in which the user can change the value of the adjustable parameter. The specific modification mode can directly input the target value, increase or decrease on the original basis, provide a plurality of fixed options for the user to select, and the like.
Further, the advanced mode interface further includes a preset time interval input box, and in some embodiments, the method may further include:
and receiving a fourth user instruction, acquiring numbers input by a user in the preset time interval input box based on the fourth user instruction, and determining the acquired numbers as the preset time interval.
It should be noted that, the preset time interval may also be set in an adjustable manner, so that the user can flexibly set the preset time interval, and the modification manner of the preset time interval may also include multiple manners.
S102: calculating the heart rate value based on a preset formula and adjustable parameters to obtain a target fan rotating speed corresponding to the heart rate value;
it should be noted that, after the heart rate value of the user is obtained, a preset formula may be used to calculate the heart rate value, so as to obtain the corresponding target fan rotation speed through conversion. The heartbeat speed can reflect the state of the user in real time, so that the target fan rotating speed can also correspond to the real-time requirement of the user, the user can accurately regulate and control the rotating speed of the fan, and the use experience of the user is improved.
It should be noted that the rest value of the heartbeat is different for different people. For example, the heart rate of a male is generally lower than that of a female, and the heart rate of an old is generally lower than that of a young, so that the adjustable parameters in the preset formula can be adjusted by a user, and the corresponding relation between the target fan rotating speed and the heart rate value can be flexibly changed to meet the demands of different users.
It should be further noted that the adjustable parameters can be adjusted according to the user's needs through an option mode and a custom mode, where the option mode is a value that a plurality of adjustable parameters are pre-stored in the system, and the value is provided for the user to select; the user-defined mode is a mode in which the user inputs a value as an adjustable parameter, and in the user-defined mode, a limit value prompt can be designed for the user to avoid danger caused by overhigh target fan rotation speed.
Further, in some embodiments, the preset formula at least includes: v2=a×v1; wherein a is an adjustable parameter, V1 is a heart beat speed, and V2 is a target fan speed.
It should be noted that, one expression of the preset formula may be as follows,
V2＝a*V1………………………………………(1)
in the formula (1), a is an adjustable parameter, the unit is m/times, V1 is heart beat speed, the unit is times/min, V2 is target fan rotating speed, the unit is m/min, and m represents distance unit'm'. The user can adjust the value of the adjustable parameter a according to the own requirement, so that the corresponding relation between the target fan rotating speed and the heartbeat speed can be flexibly changed to meet the requirements of different users. In some fault situations, the calculated target fan speed may be too high, which may create a hazard in the use of the fan, so in some embodiments, after step S102, the method may further include:
judging whether the target fan speed exceeds a maximum fan speed;
when the judging result shows that the target fan rotating speed does not exceed the maximum fan rotating speed, executing the step of controlling the fan to adjust the rotating speed based on the obtained target fan rotating speed;
And when the judging result shows that the target fan rotating speed exceeds the maximum fan rotating speed, controlling the fan to adjust the rotating speed based on the maximum fan rotating speed.
It should be noted that in some extreme cases, the calculated target fan speed may be too high, for example, the user may define the adjustable parameter too far extreme, or the heart rate monitoring device may fail, where if the fan speed is still adjusted to be too high, it may be dangerous, so it is necessary to determine whether the target fan speed is greater than the maximum fan speed. Wherein, the maximum fan rotation speed is preset and not easy to change. And if the target fan rotating speed exceeds the maximum fan rotating speed, controlling the fan rotating speed of the fan to be the maximum fan rotating speed so as to prevent danger.
S103: and controlling the fan to perform rotation speed adjustment based on the obtained target rotation speed of the fan.
The rotation speed adjustment may be performed by a variety of techniques, one of which is a continuously variable transmission technique. Continuously variable transmission is one of automatic transmission type gearboxes, and refers to a transmission system capable of continuously obtaining any gear ratio in a transmission range. The optimal matching of the drive train and the engine working condition can be obtained through stepless speed change. Common continuously variable transmissions are hydromechanical continuously variable transmissions and metal belt continuously variable transmissions, and variable bevel continuously variable transmissions.
Therefore, the corresponding target fan rotating speed is obtained through calculation of the heart rate value of the user, so that the rotating speed of the fan can be changed in real time according to the human body demand, the user does not need to manually adjust the rotating speed of the fan, and the use convenience is improved; meanwhile, the rotating speed of the fan depends on the heart rate value of a user, so that the speed of the fan can be changed in a smaller time period, the problem of long-time gear fixation of the fan is solved, and the fan can be better matched with the needs of people; meanwhile, the adjustable parameters in the preset formula also enable the control method of the fan to have flexibility, can provide differentiated control for users, and fully meets the requirements of different people.
In the current solution, the fan has the following two control modes: (1) According to the time-division control of the fan gear, the gear in different modes can be freely controlled in different time periods, and the problem of constant time and constant gear is solved; (2) The fan gear is controlled according to the indoor temperature, and the speed of the fan can be changed according to the detected change of the indoor temperature. However, in the mode according to the time-division control, the fan speed is still constant in the same period, and the more diversified demands cannot be satisfied; in the mode according to the indoor temperature control, there is a gap between the indoor temperature and the human body perceived temperature, and the speed is constant over a certain period of time, and the flexibility is not high.
The embodiment of the application provides a rotating speed control method, which can include: obtaining a heart rate value of a user; calculating the heart rate value based on a preset formula and adjustable parameters to obtain a target fan rotating speed corresponding to the heart rate value; controlling the fan to perform rotation speed adjustment based on the obtained target rotation speed of the fan; therefore, the speed of the fan can be controlled to correspond to the heartbeat speed of a human body through the rotating speed control method, and the change can be carried out on smaller time granularity, so that the problem of fixed gear of the fan is solved, and the requirement of the human body is better matched; meanwhile, differentiated control can be provided for users, and the users can adjust the corresponding relation between the rotating speed of the fan and the heart beat speed through adjustable parameters so as to meet the requirements of different users.
In another embodiment of the present application, referring to fig. 2, a flow chart of another method for controlling a rotational speed according to an embodiment of the present application is shown, as shown in fig. 2, where the method includes:

These terminal forms are within the scope of the present application.

It should be noted that, when the user selects the normal mode, the fan may be controlled by the conventional gear mode, that is, each gear corresponds to a fixed standard fan rotation speed, and when the user selects a certain gear, the fan is adjusted based on the standard fan rotation speed corresponding to the gear. In the gear mode, each gear option corresponds to a standard fan speed, which is preset, that is, the user can only adjust the fan speed to the standard fan speeds, but cannot adjust the fan speed to other values. And determining the corresponding standard fan rotating speed according to the option selected by the user, and then adjusting the fan rotating speed of the fan to the corresponding standard fan rotating speed so that the fan provides service for the user.

In addition, when the user selects the advanced mode, the rotation speed control can be performed by default directly according to the parameter set last time, and when the user needs to modify, the user enters the modification flow again, which is also within the protection scope of the embodiment of the application.
