FIG. 6 is a flowchart illustrating an operation of a fan control method according to an embodiment of the present invention. Order also.

As shown in FIG. 1, an electric fan capable of controlling the wind direction of each zone according to the present invention includes a plurality of human body sensing units 100 for measuring the presence of a person in a zone and the distance between the fan and a person, And may include a temperature sensing unit 110 for measuring a temperature and a direction and a direction controller 140 for controlling the fan unit 130 according to the control of the controller 120. Here, the fan driving unit 130 is a fan driving motor for rotating the fan of the fan, and the direction adjusting unit 140 is a rotating motor for rotating the fan.

First, the human body sensing unit 100 and the temperature sensing unit 110 detect a person located in the vicinity of the fan, measure the temperature, and transmit the result to the controller 120. For example, an infrared sensor, an ultrasonic sensor, a distance sensor, or the like may be used as the human body sensing unit 100. In the following description, an infrared sensor is used as the infrared sensor. In the infrared sensor, It detects the presence of a person with a signal. First, the infrared sensor of each zone judges the presence or absence of a person on the basis of a signal inputted in each zone. Referring to FIG. 5, the distance determiner 104 measures the distance between a person and a fan based on a time difference between a source signal and a received signal, and outputs the distance as a voltage magnitude. At this time, the control unit 120 outputs a signal to the fan driving unit 130 of the fan based on the detection result from the human body sensing unit 100 and the temperature sensing unit 110, .

If the detection result of the human body detection unit 100 is that the direction of the fan is not the same as the direction of the person located at the periphery, the controller 120 controls the direction adjusting unit 140 based on the detection result of the human body detecting unit 100 To adjust the direction of the fan.

In addition, the controller 120 controls the wind speed and the on / off state of the human body detecting unit 100 according to the distance between the fan and the user when the user is detected within a predetermined range from the fan.

Referring to FIGS. 3 and 5, the controller 120 converts a voltage value received from the human body sensing unit 100 into a distance. As the distance between the person and the fan is closer, the voltage increases because the received signal is larger. As the distance between the person and the fan increases, the voltage decreases because the received signal is smaller.

When the voltage exceeds a predetermined standard, that is, when the distance between the person and the fan is shorter than the distance set in the first section, the controller 120 controls the fan to stop the fan by sending an output to the fan driving unit 130 , And the first section may be referred to as a safety accident prevention distance. That is, the controller 120 may control the fan driving unit 130 to rapidly start the fan driving unit 130 in order to prevent a safety accident when the user approaches the first zone.

When the distance between the fan and the person is less than the first interval and the third interval, that is, the second interval, the control unit 120 controls the fan drive unit 130 to drive the fan . In addition, the control unit 120 controls the wind speed on the basis of a predetermined distance set by the controller 120 in the distance between the person and the fan. If the distance between the person and the fan is shorter than the set distance, the control unit 120 outputs an output to the fan driving unit 130 so that the motor rotates slowly to weakly control the wind speed. When the distance between the person and the fan If the distance is longer than the set distance, the control unit 120 sends an output to the fan driving unit 130 to rotate the motor rapidly, thereby strongly controlling the wind speed.

When the distance between the person and the fan exceeds the second interval, that is, the third interval, the controller 120 controls the fan drive unit 130 to stop the fan. When the third section is set so that a large number of persons are spaced apart from the fan in a moving space, unnecessary power wastage can be prevented by on / off control of the fan.

4 to 5, the controller 120 controls the fan 120 to rotate only in the area where the person is located based on the detected output signal of each zone in the human body sensing unit 100. As an example, the controller 120 Receives the encoder value attached to the rotation motor of the direction adjusting unit 140 and calculates the angle of the motor of the direction adjusting unit 140 to be rotated based on the received encoder value. In order to control the motor of the direction adjusting unit 140 to rotate according to the angle calculated by the controller 120, the controller 120 sets the value to the direction adjusting unit 140 send.

4 (a), when the human body sensing unit 100 receives the second zone input signal and outputs the second zone output signal to the control unit 120, the controller 120 controls the human body And controls the wind direction by sending an output to the direction adjusting unit 140 so as to adjust the wind direction in the second zone. That is, after the fan is rotated in the direction adjusting unit 140 so that the wind direction is adjusted only in the second zone, the direction of the fan is fixed.

(b), the control unit 120 outputs the second zone output signal and the third zone output signal from the human body detecting unit 100, and the fan is rotated in the second and third zones where the person is located based on the output signal An output is sent to the direction adjusting unit 140 so that the wind direction is controlled by controlling the wind direction.

Also, the temperature sensing unit 110 measures the temperature around the fan. The controller 120 receives the measured value from the temperature detector 110 and compares the measured value with the set temperature to perform on / off control of the pen driver 130. By controlling the fan on / off based on the ambient temperature, the fan can be automatically stopped at dawn when the temperature drops during the sleep to help people sleep and maintain health. In addition, the control unit 120 can control the wind speed to be one step higher if the ambient temperature is higher and lower the wind speed if the ambient temperature is lower.

Referring to FIG. 6, in the fan according to the present invention, the distance between the fan and the human being is positioned by the human body sensing unit 100 in the second section (S10), and the temperature sensing unit 110 If the distance between the fan and the person is within the first or third interval (S10) or the ambient temperature is lower than the predetermined temperature (S20), the fan is operated (S20) The fan is stopped (S25).

After the pen of the fan is driven, the human body detection unit 100 determines the position of a person and compares the detected position with the direction of the wind direction of the fan (S40).

If the position and direction of the person coincide with each other (S40), the wind direction zone of the fan is maintained, and if the position and the wind direction do not match (S40), the wind direction zone is controlled in the direction in which the person is located (S50) . When a person is located in multiple zones, the fan controls the turning radius to control the wind direction zone. If the distance between the fan and the person is not less than the reference distance (S60), the wind speed is controlled to be strong (S70). If the distance between the fan and the person is less than the reference distance (S60) do.

In addition, when the fan driving time is a predetermined time, for example, 2 hours or more (S80), the timer has a timer function for stopping the fan. This makes it possible to prevent a fan failure or a fire accident due to the prevention of motor overheating. On the other hand, if the fan driving time is within 2 hours (S80), the fan is operated.

Meanwhile, when the ambient temperature measured by the temperature sensing unit 110 drops below the set temperature S90 during the operation of the fan, the fan is stopped (S100). If the ambient temperature is equal to or higher than the preset temperature (S90) Is operated under the above-mentioned condition.

The above-described steps S10 to S100 are repeatedly performed until the operation of the fan is completely terminated.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken as a limitation of the scope of the present invention. Or modify it. The scope of the invention should, therefore, be construed in light of the claims set forth to cover many of such variations.
