It is compared with preset duty ratio PWM and corresponding rotational speed criteria value, the step of whether fan usability testing passes through is judged
Specifically include the following steps:
In step s 201, traversal reads the current duty ratio PWM of each fan in place, and by read it is current
The current duty ratio PWM of position fan is compared with pre-set one of duty ratio PWM.
In step S202, when the current fan in place read current duty ratio PWM and it is pre-set wherein
When one duty ratio PWM matches, traversal reads the current tachometer value of each fan, and turns what is read when forefan
Fast value is compared with the rotational speed criteria value under pre-set current duty cycle PWM, and judge to read turns when forefan
Whether speed value is consistent with the rotational speed criteria value under pre-set current duty cycle PWM.
In step S203, when reading when under the tachometer value and pre-set current duty cycle PWM of forefan
When rotational speed criteria value is consistent, then controls and return to the circulation execution one of duty ratio for sending preset value to each fan
The step of PWM.
