  • Patent number: 12267036
    Abstract: A method for controlling fans arranged in different working areas comprises: presetting a plurality of fan operation frequencies, receiving a fan operation request and adjusting a frequency of a pulse width modulation (PWM) controller to a first objective frequency based on the fan operation request, and sending the first objective frequency to the fans arranged in different working areas, to drive a first fan arranged in a first objective working area to run. Each of the plurality of fan operation frequencies corresponds to different working areas, the first objective frequency is one of the plurality of fan operation frequencies, and the first objective working area is one of the plurality of working areas corresponding to the first objective frequency. A system for controlling fans and an electronic device are also disclosed.

  • Publication number: 20170010012
    Abstract: A ventilating system includes: an electric fan including a fan motor and a fan impeller; and a control unit including a storage module storing a lookup table, a power detection circuit and a control circuit. The power detection circuit detects a power signal received by the ventilating system so as to generate a power detection signal. The control circuit generates and outputs a motor control signal associated with a target rotational speed based on an airflow input signal associated with a desired airflow volume and on the power detection signal and with reference to the lookup table. The fan motor drives the fan impeller in response to the motor control signal, so that the electric fan produces the desired airflow volume.
