CONTROL SYSTEM AND METHOD FOR FANS

摘要

A control system comprises a power distribution unit (PDU), a number of fan modules, a processing module, and a storage module. The PDU comprises a number of power-output terminals. The storage module comprises a number of programs to be executed by the processing unit. The storage module obtains power information output by the power-output terminals, and obtains corresponding control information from a mapping unit according to the power information. The storage module further generates a pulse width modulation (PWM) signal corresponding to the control information, and outputs the PWM signal to a corresponding fan module.

1. A control system, comprising:
a plurality of servers; a plurality of fan modules each configured to dissipate heat generated by one or more servers; a power distribution unit (PDU) comprising a plurality of power-output terminals providing power for the one or more servers; and a main controller comprising:
a processing module; and a storage module coupled to the processing module, and comprising a plurality of programs to be executed by the processing module, wherein the storage module comprises:a transmitting unit obtaining detected power information of the plurality of power-output terminals;a mapping unit storing control information in association with the power information of each power-output terminal;a detecting unit obtaining corresponding control information from the mapping unit according to the power information, and generating a pulse width modulation (PWM) signal corresponding to the control information; andan outputting unit outputting the PWM signal generated by the power detecting unit to the corresponding fan module.
