Document Type and Number:
WIPO Patent Application WO/2015/172597
Kind Code:
A1
Abstract:
A method and system for controlling multiple blowers. The method comprises: generating more than two pulse width modulation signals that have different duty cycles; according to a rotation speed required by each blower, selecting from the more than two pulse width modulation signals a corresponding pulse width modulation signal for each blower, and outputting a rotation speed control signal of each blower according to the selected pulse width modulation signal; and outputting the rotation speed control signals of all the blowers to the corresponding blowers. The technical scheme of the present invention can implement centralized control of multiple blowers, reduce the complexity of a circuit for implementing the multiple blowers, and facilitate unified management of devices.
