FAN SPEED CONTROL SYSTEM AND FAN SPEED READING METHOD THEREOF
First Claim
1. A fan speed control system, having a rack and a plurality of servers disposed on the rack, wherein the fan speed control system further comprises:
- a management module coupled to the servers; and
a plurality of fan module disposed on the rack and coupled to the management module for dissipating heat from the servers, wherein each of the fan modules further comprises;
a plurality of fans;
a speed control module coupled to each of the fans; and
at least one main control module having a primary communication port, wherein, when any one of the main control modules enters an interrupt sequence, the main control module which enters the interrupt sequence receives a control signal sent from the management module through the primary communication port, and delivers the control signal to the speed control module for reading a rotation speed value of each of the fans.

Abstract
A fan speed control system includes a rack and a plurality of servers disposed on the rack. The fan speed control system further includes the management module and the fan module. The management module is coupled to the servers, and the fan module is coupled to the management module for dissipating the heat from the servers. The fan module contains the fan, the speed control module, and the main control module. The speed control module is coupled to the fans. The main control module has a primary communication port. The main module which enters the interrupt sequence receives the control signals sent from the management module through the primary communication port when any one of the main modules enters the interrupt sequence. The control signal is delivered to the speed control module for reading the fan speed.

7. A fan rotation speed reading method of a fan speed control system, for reading a fan rotation speed value, comprising:
-
initializing at least one speed control module; detecting whether a main control module enters an interrupt sequence when the initialization of the speed control module is completed; and receiving a control signal sent from the management module by the main control module which enters the interrupt sequence through a primary communication port when the main control module enters the interrupt sequence, and delivering the control signal to the speed control module for reading the fan rotation speed value. - View Dependent Claims (8, 9, 10)
