IDENTIFICATION SYSTEM AND ELECTRONIC SYSTEM FOR IDENTIFYING A FAN TYPE OF A FAN |
摘要 |
A fan identification system identifies a fan type of a fan in an electronic system. The fan identification system includes a controller that includes: a setting module for setting a fan identification characteristic value corresponding to a pulse width modulation duty cycle with a substantial maximum difference between a fan speed of a first type of fan and a fan speed of a second type of fan; a reading module for reading a stable fan speed value after the fan receives the fan identification characteristic value and is initiated with the fan identification characteristic value; and an identification module for identifying the fan as the first type of fan or the second type of fan based on which fan has a predetermined fan speed that is the closest to the stable fan speed value when operating at the fan identification characteristic value. |
