Detailed Description
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same elements or elements having the same functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present invention and should not be construed as limiting the present invention, and all other embodiments that can be obtained by one skilled in the art based on the embodiments of the present invention without inventive efforts shall fall within the scope of protection of the present invention.
In order to solve the above technical problem, the present invention provides a method for controlling an intelligent fan, and referring to fig. 1, the method for controlling an intelligent fan includes the following steps:
step S10, receiving a first wind speed curve sent by a mobile terminal or a server and used for controlling the operation of the intelligent fan, wherein the first wind speed curve is set by a user in a self-defined manner; in this step, the smart fan is provided with a first communication module, preferably a wifi module, a zigbee module and a bluetooth module, and the mobile terminal and the smart fan can be connected with mobile terminals or servers such as mobile phones through the first communication module. The first wind speed curve is set by a user on the mobile terminal in a self-defining mode, and specifically is a wind speed-time curve. And displaying an initial wind speed curve on a setting interface of the mobile terminal, wherein the abscissa of the initial wind speed curve is a time coordinate, the ordinate of the initial wind speed curve is a wind speed coordinate, and the wind speed of the initial wind speed curve is a constant value. When the wind speed control device is set, a user can click any point on a wind speed curve or any time period to move up and down along the ordinate so as to adjust the wind speed at the corresponding moment or time period. In addition, the server acquires a night temperature change curve from the internet according to the geographical position of the mobile terminal of the user, and calculates a reference wind speed curve according to the night temperature change curve, wherein the first wind speed curve can be set by the user in a self-defining way according to the reference wind speed curve pushed by the server. Because the metabolism of the human body is slowed down when the human body sleeps, the body generates less heat, and the air temperature at the later night is also reduced, the air speed of the first air speed curve after the human body falls asleep should be reduced when the first air speed curve is set by a user.
Step S20, controlling the intelligent fan to operate according to the first wind speed curve; after the intelligent fan receives the first wind speed curve through the first communication module, the control MCU inside the intelligent fan controls the rotating speed of the fan through a built-in speed regulator of the intelligent fan according to the first wind speed curve to realize the control of the wind speed. Wherein the control MCU can select stm32 low-power consumption singlechip, the fan motor is respectively connected with the power supply 70 and the control MCU through the speed regulator, and the power supply 70 supplies power. Other functional modules in the smart fan are also powered by the power supply 70. When the ac power supply is used, the speed controller 30 can select a silicon controlled speed control mode, and when the dc power supply is used, the speed controller 30 can select a speed control mode such as a triode or an MOS transistor. According to the intelligent control system, the wind speed of the fan is intelligently adjusted through the first wind speed curve to adapt to the requirements of a human body, so that the output power of the motor is correspondingly reduced after a user falls asleep, and in practical application, the effects of energy saving and power saving can be achieved no matter the fan is driven by an alternating current power supply or a direct current power supply. The power supply 70 may be a rechargeable battery, and the present invention can also improve the endurance of the battery due to the above energy saving effect. According to the intelligent fan control method and device, the intelligent fan is controlled to operate by acquiring the first wind speed curve which is sent by the mobile terminal or the server and used for controlling the intelligent fan to operate, cold caused by large heat dissipation of the body surface of a user due to high wind speed is avoided, and the problems that in the prior art, the fan is single in operation mode and poor in adaptability are solved.
Referring to fig. 2, after step S20, the method for controlling a smart fan further includes:
step S30, obtaining environmental temperature information; in this step, a first temperature sensor for measuring ambient temperature information may be disposed on the fan, and may be disposed on the casing where the outlet channel of the bladeless fan is located or on the mesh enclosure of the conventional electric fan, so that the indoor temperature may be measured during the shaking process.
Step S40, a second wind speed curve is synthesized according to the environment temperature information and by combining the first wind speed curve; in this step, because the first wind speed curve set by the user in the sleep process is not completely suitable for the sleep state and the metabolic state of each stage of the user, the MCU is controlled to correct the first wind speed curve according to the environment temperature, so that the wind speed of the fan is suitable for the sleep state of the user. Specifically, the first wind speed curve is generally kept at a higher wind speed for a certain period of time before and after falling asleep, so as to create a better falling asleep environment temperature. When the metabolism of the user is reduced after the user falls asleep for a period of time, the heat productivity of the body is reduced, and meanwhile, due to weather reasons or heat loss of buildings at the front and back midnight, the change of the ambient temperature is large, and the MCU is controlled to correct the first wind speed curve according to the measured real-time ambient temperature. For example, when the ambient temperature is 36 ℃, the rotation speed of the smart fan is controlled to be 1000-1200 rpm, when the ambient temperature is reduced to 26 ℃, the wind speed (corresponding to the rotation speed of the smart fan) in the first wind speed curve is reduced by 60 rpm for every 1 ℃ reduction of the temperature during the period of reduction of the ambient temperature, and finally the rotation speed in the sleep stage is maintained to be 280-480 rpm, so that the ambient temperature is ensured to be friendly to users. When the ambient temperature is lower than 26 ℃, the intelligent fan stops running at the moment, the positive correlation between the wind speed and the ambient temperature (within the temperature range of 26-36 ℃) is ensured, and the condition that the sleep quality is influenced due to the fact that a user feels overheated or too cool is avoided.
And step S50, controlling the intelligent fan to operate according to the second wind speed curve. In this embodiment, the control MCU inside the smart fan controls the rotation speed of the fan according to the second wind speed curve to control the variation of the wind speed.
According to the intelligent fan control method and the intelligent fan control system, the intelligent fan is controlled to operate by acquiring the first wind speed curve which is sent by the mobile terminal or the server and used for controlling the intelligent fan to operate, meanwhile, the first wind speed curve is adjusted and synthesized into the second wind speed curve according to the ambient temperature, the intelligent fan is controlled to operate according to the second wind speed curve, and the problem that the heat on the body surface of a user is greatly dissipated due to the fact that the wind speed is high and the cold is caused is avoided.
Referring to fig. 3, after step S50, the method for controlling a smart fan further includes:
step S60, obtaining real-time vital sign parameters of the user; in this step, first communication module can be wifi module and bluetooth BLE wireless transceiver module etc. among the smart fan, from this can communicate with the intelligent bracelet that the user wore and acquire the real-time vital sign parameter of user that intelligent bracelet monitored. The vital sign parameters include respiration, body temperature, pulse, blood pressure, etc. Above-mentioned vital sign parameter's acquireing is not only limited to acquire through this mode of intelligent bracelet, also can set up and possess the intelligent detection instrument of wireless communication function with intelligent fan is supporting, and this intelligent detection instrument can realize the monitoring by wearing modes such as watchband, armband, waistband, clothes and the limbs contact of user.
And S70, generating a third wind speed curve for controlling the intelligent fan to operate according to the vital sign parameters and the second wind speed curve. A Two-Process theoretical Model (Two-Process Model) for sleep regulation was proposed by the scientist Alexander Borbely. The sleep of a person in the sleep model can be divided into slow wave sleep and fast wave sleep, the person starts to enter the slow wave sleep (the duration is 60-80 min) after falling asleep, then shifts to the fast wave sleep (the duration is 20-30 min), and then the two sleep modes are alternately carried out. A person typically experiences 4 to 6 sleep cycles during a prolonged period of rest. In slow wave sleep, the metabolism of a person is slowed down, the body temperature is slowly reduced, the sweating function is enhanced, and the wind speed is correspondingly reduced. During the fast wave sleep period, the metabolism of the human body is enhanced, and the heart rate and the blood pressure rise and the wind speed need to be enhanced. Under the non-interference state, the human body generally enters the sleep within 10-20 min. In the step, the intelligent fan judges which sleep stage the user is specifically in according to the acquired vital sign parameters, and correspondingly adjusts the real-time wind speed so as to ensure that the body surface area temperature of the user is kept at a normal level, avoid the user from feeling overheating or overcooling, and realize autonomous dynamic adjustment. The real-time wind speed magnitude may then be converted into a time-dependent third wind speed curve. Specifically, the wind speed in the third wind speed curve within 10-20 min before falling asleep also needs to be kept at a higher level, so as to reduce the ambient temperature around the user to create better falling asleep conditions. And combining the sleep model and the environment temperature information, in a plurality of next sleep cycles, the wind speed is reduced corresponding to the slow wave sleep period, and the wind speed is increased again corresponding to the fast wave sleep period. The wind speed can be accurately and autonomously adjusted through the real-time vital sign parameters of the user, so that the wind speed adjusting method is more friendly to the user and higher in applicability and intelligence degree.
Further, the method for controlling the smart fan after S70 further includes: and sending the second wind speed curve and the third wind speed curve to a mobile terminal and a server and storing the second wind speed curve and the third wind speed curve. In this embodiment, the second wind speed curve and the first wind speed curve may also be uploaded to the server and the mobile terminal as sleep record information of the user, and the user may view the history in real time and track sleep quality over a period of time.
The present invention also proposes a smart fan, referring to fig. 4, comprising a first communication module 20, a control MCU10 and a temperature monitoring module 50, wherein: the first communication module 20 is configured to receive a first wind speed curve sent by the mobile terminal 60 or the server and used for controlling the operation of the smart fan, where the first wind speed curve is set by a user in a self-defined manner; the control MCU10 is used for controlling the intelligent fan to operate according to the first wind speed curve; the temperature monitoring module 50 is used for acquiring environmental temperature information; the control MCU10 is also used for synthesizing a second wind speed curve according to the environmental temperature information and by combining the first wind speed curve; the control MCU10 is also used to control the smart fan to operate according to a second wind speed profile.
In this embodiment, the first communication module 20 is preferably a wifi module, a zigbee module or a bluetooth module, and the mobile terminal 60 and the smart fan can be connected to the mobile terminal 60 such as a mobile phone or a server through the first communication module 20. The first wind speed curve is set by the user on the mobile terminal 60 in a user-defined manner, specifically, a wind speed-time curve. The mobile terminal 60 comprises a mobile phone, a tablet computer, an intelligent bracelet and the like, and the intelligent fan can be controlled through APP (application program) and WeChat public numbers on the mobile terminal 60 or small programs. In addition, the user can control the intelligent fan through the PC side. Because metabolism can be slowed down when people sleep, and body heating is reduced, the wind speed of the first wind speed curve after falling asleep should be reduced when the first wind speed curve is set by users. After the intelligent fan receives the first wind speed curve through the first communication module 20, the control MCU10 in the intelligent fan controls the rotating speed of the fan through the speed regulator 30 built in the intelligent fan according to the first wind speed curve to realize the control of the wind speed. Wherein the control MCU10 can select the stm32 low-power consumption singlechip. The control MCU10 of the smart fan receives the first wind speed curve and then converts the first wind speed curve into a corresponding control command, which is a time-fan motor power command, i.e., controls the output power of the fan motor 40 according to a time axis. The speed regulator 30 connected with the control MCU10 can control the magnitude of the load current loaded on the fan motor 40 to control the rotation speed of the fan motor 40 in a corresponding time to achieve the function of controlling the wind speed of the smart fan, specifically, the fan motor 40 in the smart fan is connected with a power supply 70(AC power supply or DC power supply) through the speed regulator 30 and powered by the power supply 70. Other functional modules in the smart fan are also powered by the power supply 70. When the AC power supply is used, the speed controller 30 can select the speed control mode of the silicon controlled rectifier, and when the DC power supply is used, the speed controller 30 can select the speed control mode of a triode or an MOS tube and the like. According to the intelligent control system, the wind speed of the fan is intelligently adjusted through the first wind speed curve to adapt to the requirements of a human body, so that the output power of the motor is correspondingly reduced after a user falls asleep, and in practical application, the effects of energy saving and power saving can be achieved no matter the fan is driven by an alternating current power supply or a direct current power supply. The power supply 70 may be a rechargeable battery, and the present invention can also improve the endurance of the battery due to the above energy saving effect.
The temperature monitoring module 50 includes a first temperature sensor disposed on a housing where the air outlet channel of the bladeless fan is located or on a mesh enclosure of a conventional electric fan, so that the indoor temperature can be measured during the shaking process. Because the first wind speed curve set by a user in a self-defined mode is not completely suitable for the sleeping state and the metabolic state of each stage of the user when the user sleeps, the MCU10 is controlled to correct the first wind speed curve according to the environment temperature, and the wind speed of the fan is suitable for the sleeping state of the user.
Further, the first communication module 20 is further configured to obtain a vital sign parameter of the user; the control MCU10 is also used to generate a third wind speed profile for controlling the smart fan to operate based on the vital sign parameters and the second wind speed profile. In this embodiment, first communication module 20 can be wifi module and bluetooth BLE wireless transceiver module etc. among the smart fan, from this can communicate with the intelligent bracelet that the user wore and acquire the real-time vital sign parameter of user that the intelligent bracelet monitored. The vital sign parameters include respiration, body temperature, pulse, blood pressure, etc. Above-mentioned vital sign parameter's acquireing is not only limited to acquire through this mode of intelligent bracelet, also can set up and possess the intelligent detection instrument of wireless communication function with intelligent fan is supporting, and this intelligent detection instrument can realize the monitoring by wearing modes such as watchband, armband, waistband, clothes and the limbs contact of user.
The scientist Alexander Borbely proposed a Two-process theoretical model for sleep regulation (Two-Process model). The sleep of a person in the sleep model can be divided into slow wave sleep and fast wave sleep, the person starts to enter the slow wave sleep (the duration is 60-80 min) after falling asleep, then shifts to the fast wave sleep (the duration is 20-30 min), and then the two sleep modes are alternately carried out. A person typically experiences 4 to 6 sleep cycles during a prolonged period of rest. In slow wave sleep, the metabolism of a person is slowed down, the body temperature is slowly reduced, the sweating function is enhanced, and the wind speed is correspondingly reduced. During the fast wave sleep period, the metabolism of the human body is enhanced, and the heart rate and the blood pressure rise and the wind speed need to be enhanced. Under the non-interference state, the human body generally enters the sleep within 10-20 min.
Specifically, the control MCU10 determines which sleep stage the user is specifically in according to the obtained vital sign parameters, and adjusts the real-time wind speed accordingly to ensure that the body surface area temperature of the user is kept at a normal level, thereby avoiding the user from feeling overheating or overcooling, and realizing autonomous dynamic adjustment. The real-time wind speed magnitude may then be converted into a time-dependent third wind speed curve. Specifically, the wind speed in the third wind speed curve within 10-20 min before falling asleep also needs to be kept at a higher level, so as to reduce the ambient temperature around the user to create better falling asleep conditions.
