Problems solved by technology

This method increases labor costs
2) Setting the fan control strategy according to the high-altitude configuration will make the fan provide excessive cooling air volume in low-altitude areas. The disadvantage of this method is that for electronic equipment located in low-altitude areas, high-power fans will not only Increased energy consumption and high noise

Abstract

The invention provides a method and a system for controlling the rotating speed of a fan. The system comprises a monitoring unit for monitoring the work environment of electronic equipment and further comprises a temperature monitoring module and a power monitoring module, wherein the temperature monitoring module is positioned at an air inlet and an air outlet of the electronic equipment and is used for respectively monitoring and outputting the temperatures at the air inlet and the air outlet; and the power monitoring module is used for monitoring and outputting the power of the electronic equipment; and a control unit is connected with the monitoring unit and the fan and is used for calculating the temperature difference between the air inlet and the air outlet after the temperatures outputted by the temperature monitoring module at the air inlet and the air outlet are received as well as the power of the electronic equipment outputted by the power monitoring module, obtaining the air density in the environment where the electronic equipment is positioned based on the temperature difference, the power and the rotating speed of the fan, and controlling the rotating speed of the fan based on the air density. Therefore, the rotating speed of the fan can be intelligently changed.

Description

technical field [0001] The present invention relates to a control method, in particular to a method and system for controlling fan speed. Background technique [0002] Fan-based air cooling technology is the most common way to cool electronic equipment. Specifically, the greater the air volume output by the fan per unit time, the better the heat dissipation effect, but at the same time, the air volume is proportional to the power. For low-altitude areas and high-altitude areas, the fan with the same power provides Thermal performance varies widely. This is mainly due to the difference in air density at different altitudes, and the amount of air per unit volume output by a fan with the same power at different altitudes varies greatly. However, the current fan control strategy only relies on the air inlet and outlet of the electronic device or the temperature of the electronic device to adjust the fan speed, without considering the influence of air density on the fan. For t...
