Definitions

  • the subject matter herein generally relates to a rotation speed control system and control method of a fan.
  • a fan can be used for cooling.
  • FIG. 1 is a block diagram of a fan rotation speed control system.
  • FIG. 2 is a flowchart of a fan rotation speed control method.
  • FIG. 1 illustrates a rotation speed control system of a fan 10 includes a blade group 12 , a motor 14 , a storage unit 16 , a switch unit 18 , a temperature sensing unit 20 and a controlling unit 22 .
  • the rotation speed control system of the fan 10 is configured to automatically adjust a rotation speed of the blade group 12 according to a temperature of a local environment of the fan 10 .
  • the storage unit 16 is configured to store a relationship between a temperature and a motor speed.
  • the temperature in the relationship is from 28 to 36.
  • the motor speed in the relationship is from 500 revolutions per minute to 1500 revolutions per minute. High temperature is corresponding to high motor speed.
  • the switch unit 18 is configured to control the fan 10 to turn on and turn off.
  • the temperature sensing unit 20 is configured to sense the temperature of the local environment when the fan 10 is turned on.
  • the temperature sensing unit 20 may be a circuit including a thermistor. A resistance of the thermistor is increased with a rise of the temperature. When the resistance is changed, an output voltage of the circuit is changed.
  • the temperature sensing unit 20 obtains the temperature of the environment according to the output voltage. In the embodiment, the temperature sensing unit 20 periodically senses the temperature of the environment according to a preset period, for example, two hours. In another embodiment, the temperature sensing unit 20 senses the temperature of the environment in real time.
  • the controlling unit 22 is configured to control the motor 14 to rotate in a speed corresponding to the sensed temperature according to the sensed temperature and the relationship.
  • the motor 14 is configured to drive the blade group 12 to rotate.
  • the temperature in the relationship includes a preset critical temperature, for example, 25.
  • the controlling unit 22 is further configured to control the switch unit 18 to turn the fan 10 off when the temperature of the environment is below the preset critical temperature. Therefore, the fan 10 turns off when the temperature of the environment is below the preset critical temperature.
  • the control system of rotation speed of a fan 10 further includes a display unit 24 .
  • the display unit 24 is configured to display the current temperature of the environment.
  • FIG. 2 a flowchart is presented in accordance with an example embodiment.
  • the example method is provided by way of example, as there are a variety of ways to carry out the method. The method described below can be carried out using the configurations illustrated in FIG. 1 , for example, and various elements of these figures are referenced in explaining example method.
  • Each block shown in FIG. 2 represents one or more processes, methods or subroutines, carried out in the example method.
  • the illustrated order of blocks is illustrative only and the order of the blocks can change according to the present disclosure. Additional blocks can be added or fewer blocks may be utilized, without departing from this disclosure.
  • the example method can begin at block 102 .
  • the temperature sensing unit 20 senses the temperature of the environment where the fan 10 is located when the fan 10 is activated. In the embodiment, the temperature sensing unit 20 periodically senses the temperature of the environment according to a preset period, for example, two hours. In another embodiment, the temperature sensing unit 20 senses the temperature of the environment in real time.
  • the controlling unit 22 controls the motor 14 of the fan 10 to rotate at a speed according to the sensed temperature of the local environment and a relationship between a temperature and a motor speed.
  • the temperature in the relationship is from 28 to 36.
  • the motor speed in the relationship is from 500 revolutions per minute (RPM) to 1500 RPM. High temperature is corresponding to high motor speed.
  • the motor 14 drives the blade group 12 to rotate.
  • the flowchart of a control method of a rotation speed of a fan 10 further includes block 108 and block 110 .
  • the display unit 24 displays the sensed temperature of the environment.
  • the controlling unit 22 turns off the fan 10 when the temperature of the environment is below a preset critical temperature, for example, 25.
