Fan abnormal state protection method and system

Abstract

The invention discloses a fan abnormal state protection method and system. The fan abnormal state protection method is suitable for an electronic device, and the electronic device comprises a fan, a temperature sensor and a processor. The fan abnormal state protection method comprises the steps that when it is judged that the rotating speed of a fan is greater than or equal to a preset rotating speed upper limit and judging that the temperature measured by the temperature sensor is greater than or equal to a preset temperature upper limit, the efficiency of the processor is limited; when it is judged that the rotating speed is less than the preset rotating speed upper limit, whether the rotating speed is less than or equal to a first reduction rotating speed is judged; and limiting of the performance of the processor is stopped when the rotating speed is smaller than or equal to the first reduction rotating speed. The electronic device can be protected when the fan is in an abnormal state, so that the temperature of the electronic device can be effectively prevented from continuously rising.

Description

[Technical field] [0001] The present invention relates to a method of protecting a protective method applied to an electronic device, in particular a fan abnormal state, and a system. 【Background technique】 [0002] The current electronics generates high heat due to its internal electronic components themselves, so that all heat dissipation elements are needed to stabilize the system. In terms of the system positioning, its heat dissipation design is mainly divided into four categories of fan design (with fan design), and two types of heat dissipation design have its own advantages. [0003] For systems that are currently more than a high cooling wattage demand, there is a fan design for most heat dissipation design. However,,,,,,,,,,,,,,,,,,,,,,,,,,,,, " Inside components, the surface temperature of the system can cause the user's skin burns, which is more attached to the label, tablet, etc. [Summary] [0004] SUMMARY OF THE INVENTION An object of the present invention provides...

AI Technical Summary

Problems solved by technology

However, for example, when the system is improperly used and the air inlet and outlet of the fan are blocked, or when the fan fails or is blocked by a foreign object and the operation is not smooth, the cooling effect of the system will be poor, which will affect the performance of the system or damage the system. In addition, the high surface temperature of the system may cause burns to the user's skin. These problems are also paid more attention to handheld products such as notebook computers and tablet computers.
