Abstract
A fan control device for controlling a fan includes a communication-processing processor, a fan-controlling processor, and a detection processor. The communication-processing processor receives a fan-controlling instruction from an external system to generate a control signal, generates a detection signal according to a detection request of the external system, and provides state information for the external system. The fan-controlling processor controls the speed of the fan according to the control signal and transmits a control result to the communication-processing processor. The detection processor detects the ambient state and the fan state of the fan according to the detection signal, and generates the state information according to the ambient state and the fan state. The communication-processing processor, the fan-controlling processor, and the detection processor are physically separated from one another.
