CONTROL SYSTEM AND METHOD FOR CONTROLLING SERVER

1 . A control system comprising:

a battery;

a power supply coupled to the battery and configured to provide power to a server system;

a temperature sensor configured to sense a temperature of the server system;

a baseboard management controller (BMC) coupled to the temperature sensor and configured for setting a preset temperature, the BMC configured to detect an operation state of the power supply, the BMC obtain the temperature of the system from the temperature sensor, and compare the temperature of the system transmitted by the temperature sensor with the preset temperature; and

a warning module coupled to the BMC;

wherein when the power supply leaves off power for the server system, the battery provides power to the BMC;

wherein when the temperature of the system obtained by the BMC is higher than the preset temperature, the BMC outputs a first warning signal to the warning module and when the temperature of the system obtained by the BMC is low than the preset temperature, the BMC outputs a second warning signal to the warning module; and

wherein the warning module is configured to output a first warning information and a second warning information corresponding to the first warning signal and the second signal transmitted by the BMC.

2 . The control system of claim 1 , wherein the control system comprises a pulse width modulation (PWM) and a fan, both the BMC and the fan are electrically coupled to the PWM, the BMC controls the operation states of the fan through the PWM.

3 . The control system of claim 2 , wherein when the power supply provides power to the server system and the temperature of the system obtained by the BMC is higher than the preset temperature, the BMC outputs a control signal to the PWM control module, the PWM control module obtains the control signal and adjusts the speed of the fan according to the control signal transmitted by the BMC.

4 . The control system of claim 3 , wherein the PWM control module adjusts the ratio of the duty cycle of a pulse signal to the fan to adjust the speed of the fan according to the control signal transmitted by the BMC.

5 . A control method comprising:

detecting a operation states of a power supply by a basic management controller (BMC), and supplying power to the BMC by a battery when the power supply leaves off power supply for a server system;

sensing the temperature in the server system by a temperature sensor, and transmitting the temperature of the server system to the BMC;

setting a preset temperature and obtaining the temperature from the temperature sensor by the BMC, and comparing the temperature transmitted by the temperature sensor with the preset temperature;

outputting a first warning signal by the BMC when the temperature transmitted by the temperature sensor is higher than the preset temperature;

outputting a second warning signal by the BMC when the temperature transmitted by the temperature sensor is lower than the preset temperature; and

obtaining the first warning signal and the second warning signal from the BMC by a warning module, and corresponding outputting a first warning information and a second warning information according the first warning signal and the second signal transmitted by the BMC.

6 . The control method of claim 5 , wherein when the power supply provides power to the server system and the temperature of the system obtained by the BMC is higher than the preset temperature, the BMC outputs a control signal to a PWM control module, the PWM control module obtains the control signal and adjusts the speed of a fan according to the control signal transmitted by the BMC.

7 . The control method of claim 6 , wherein the PWM control module adjusts the ratio of the duty cycle of a pulse signal to the fan to adjust the speed of the fan according to the control signal transmitted by the BMC.
