The present invention relates to a smart fan using a sensor having an infrared sensor, an ultrasonic sensor and an illuminance sensor, and relates to controlling the direction and wind speed of the fan by the operation of a control unit according to signals of an infrared sensor, an ultrasonic sensor and an illuminance sensor.

More particularly, the present invention relates to a fan control device for controlling a fan speed of an electric fan, a direction controller for controlling a direction of the fan blades, an infrared sensor for recognizing the position of a person, an ultrasonic sensor for measuring a distance to a fan, And a light intensity sensor for measuring light intensity.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, a configuration of a smart fan according to the present invention will be described.

1, a smart fan according to the present invention is equipped with a head of an electric fan 100 and an ultrasonic sensor 200 below the ultrasonic sensor 200, and an infrared sensor 300 is attached under the ultrasonic sensor 200 And the illuminance sensor 400 is attached to the base of the fan.

The infrared sensor 300 senses the ambient temperature and inputs a measurement signal to the control unit to control the power of the fan according to the input value.

Referring to FIG. 5, the infrared sensor 200 recognizes a person and inputs a signal to the controller, and controls the direction controller 700 according to the received signal value. The control unit 500 controls the direction adjusting unit to direct the head 100 of the fan toward the position of the person, thereby preventing unnecessary power waste such as operating in the air.

In addition, the smart fan using the sensor controls the wind speed according to the temperature measured by the infrared sensor. In this case, the wind speed is controlled according to the arbitrary temperature interval.

The temperature interval is divided into a first temperature interval, a second temperature interval, and a third temperature interval, which are arbitrarily divided according to convenience. A first temperature is the lowest temperature range, a temperature higher than the first temperature range is referred to as a second temperature range, and a temperature range higher than the second temperature range is referred to as a third temperature range.

 The control unit receiving the measured temperature value from the infrared sensor stops operation of the fan if the measured temperature value is less than the first temperature range and has the wind speed of the weak wind when the temperature is within the first temperature range and less than the second temperature range, The temperature of the parasitic wind is less than the second temperature range and the temperature of the third temperature range is higher than the second temperature range.

Referring to FIG. 2, when a person is detected within a predetermined distance from the fan through the ultrasonic sensor 200, the controller 500 receives the value and controls the wind speed of the fan according to the input value.

Referring to FIGS. 3 and 4, the controller 500 converts a voltage value received from the ultrasonic sensor 200 into a distance. At this time, the voltage increases as the distance between the person and the fan increases, and decreases as the distance between the person and the fan increases.

When the voltage exceeds a certain level, that is, when the person and the fan are in close proximity to each other, the control unit 500 sends an output to the fan driving unit 600 to control the fan to stop.

In this case, it is possible to divide the distance section according to the distance value converted from the voltage magnitude. When the fan and the person are in close proximity to each other, the first distance section, the second distance section, Distance section, and fourth section section.

The infrared sensor recognizes that the distance between the person and the fan is in the first distance zone, and inputs the value to the controller 500. The control unit 500 controls the fan driving unit 600 to be driven by the weak wind.

In the second distance section, the control unit 500 controls the fan driving unit 600 to be driven by the parasitic wind. In the third distance interval, the controller receives the strong wind and the fourth distance interval or longer. So that it is convenient.

Meanwhile, in the present invention, the control unit controls the wind speed of the fan driving unit according to the sensing values of the infrared sensor 300 and the ultrasonic sensor 200. In order to minimize the malfunction due to the sensing value recognized at one time, The sensing value is weighted and prioritized to control the motion.

Even if the infrared sensor 300 recognizes the existence of a person in the infrared sensor 300 due to a safety problem in the first distance section, that is, in the 0th distance section when the infrared sensor 300 and the ultrasonic sensor 200 operate, The control unit 600 and the direction adjusting unit 700 are not operated, so that the operation of the fan is temporarily stopped.

In the first distance section, the control unit places a weight on the ultrasonic sensor 200. Therefore, the operation of the fan driving unit does not occur according to the change in the sensing value of the infrared sensor 300, so that the wind speed is not increased even if the temperature of the peripheral portion 300 is measured through the infrared sensor in the first distance section.

In the second distance section, when the temperature of the peripheral portion is constant, the controller receives the sensing value of the ultrasonic sensor 200 preferentially and measures the distance between the fan and the person to adjust the wind speed of the fan.

On the other hand, when the distance is constant, the controller preferentially receives the sensing value of the infrared sensor 300 and adjusts the wind speed of the fan driving unit according to the temperature of the peripheral part.

At the third distance, the control unit 500 places a weight on the infrared sensor 300. Since the control unit 500 receives and controls the sensing value of the infrared sensor 300 prior to the sensed value of the ultrasonic sensor 200, if the temperature of the peripheral portion is measured to be low in the third distance interval, .

The ultrasonic sensor 200 is weighted in the fourth distance section or longer. In the fourth distance section, the ultrasonic sensor detects that the person is out of a certain range from the fan, so that the fan is stopped.

Meanwhile, when the illuminance sensor 400 is operated, the controller can adjust the wind speed by adjusting the fan driving unit according to the measured illuminance value. The illuminance when the illuminance at night is measured and the illuminance when the illuminance is less than 6 [Lx] is called the night illuminance. When the illuminance at night is illuminated, the controller 500 receiving the signal performs an OFF operation after a predetermined time When you forget to turn off the power at night, you can control the fan so that the fan keeps running to prevent colds or death.

In the case of night illumination, the illuminance value changes for a certain time due to the change in illuminance due to watching a TV, etc., and the difference between the minimum value and the minimum value of the measured value for one minute is 20 to 50 Lx, The illuminance measured when doing so is called TV illuminance.

When the illuminance sensor 400 measures a predetermined illuminance value in the night illumination, that is, the TV illuminance and inputs the measurement value to the control unit 500, the control unit 500 controls the operation of the fan driving unit 600 to control the wind speed of the weak wind . This is because when the TV is watched before going to bed, the nighttime is also measured by turning off the fan so that the fan is not turned off but operated as a weak wind to increase the convenience of use.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope of the present invention. The scope of the invention should therefore be construed in light of the claims set forth to cover many of such variations.
