Abstract:
Systems and methods for fan typing and anomaly detection may provide a pulse width modulation (PWM) control signal with a predetermined threshold duty cycle to a fan, receive a tachometer signal from the fan while the PWM control signal has the threshold duty cycle, and compare the frequency of the tachometer signal (expressed in revolutions per minute) to an expected tachometer frequency for fans of a first fan type with the PWM control signal having the threshold duty cycle, according to an RPM vs. PWM curve specified for fans of the first fan type. The systems and methods may determine, based on the comparison, that the fan is of the first fan type and provide an indication that the fan is of the first fan type to a fan controller. Deviations from expected tachometer responses may indicate an anomaly, such as an actual fan failure or a predicted fan failure.

Claim (Index 10):
The method of  claim 1 , further comprising:\n calculating a first average frequency of the tachometer signal output by the first fan during a first time period in which the PWM control signal has the first PWM duty cycle; generating a first data structure representing a histogram comprising multiple bins, wherein each bin represents a respective range of tachometer frequency values for the tachometer signal output by the first fan during the first time period and each bin is associated with a respective count value indicating the number of occurrences of a tachometer frequency value for the tachometer signal falling within the respective range of tachometer frequency values represented by the bin during the first time period; determining a predetermined number of top bins associated with the highest respective count values in the first data structure; and saving reference data representing one or more of the calculated average frequency, identifiers of the top bins in the first data structure, and the respective count values associated with the top bins.
