Abstract

The invention relates to a display screen controller fan speed regulation method and device and a machine readable storage medium. The display screen controller fan speed regulation method comprises the following steps that a working environment temperature and a working chip temperature are acquired, a fan speed value FanA is determined by using a working environment temperature conversion curve,a fan speed value FanB is determined by using a working chip temperature conversion curve, the fan speed value is determined through comparison of the difference between the fan speed value FanA andthe fan speed value Fanb with a fan adjusting gear value Fandmax / 10, and the speed is regulated and the fan speed value is stored. A display screen controller is subjected to zoning, and is used for acquiring and calculating data of the working environment temperature and the working chip temperature, the speed regulation is controlled, the use efficiency of a fan is improved, the heat dissipationeffect is improved, the service life of various equipment in the controller is prolonged, the energy is saved, and the noise and raised dust of the fan are reduced.

Description

technical field [0001] The present invention relates to the field of controllers, in particular to a fan speed regulation method, device and machine-readable storage medium of a display screen controller. Background technique [0002] At present, the fan cooling system of the mainstream display screen controller usually uses the ambient temperature acquisition module to obtain the temperature of the acquisition point. In the prior art, the temperature of the collection point used for calculation is the ambient temperature of a single-use device, or the temperature of multiple processors in the device is collected and the average temperature of the processors is obtained through calculation. Through the training curve corresponding to the temperature of the collection point to the fan speed, or setting the conversion table of the temperature of the collection point corresponding to the fan speed according to the experience value, the fan speed of the controller for the displa...

AI Technical Summary

Problems solved by technology

The existing technology can only pre-set the conversion table from the temperature of the collection point to the fan speed based on the empirical value, or use the ambient temperature of a single or multiple devices as the temperature of the collection point, and after simple average calculation, the fan speed can be obtained, and Control the fan speed of the controller for the LED display

The existing technology cannot accurately divide the areas of each processor, nor can it individually control the speed of fans in each area, resulting in the inability to solve the problem of heat concentration caused by high local loads

If all the fans operate at the same time, it will cause waste of power resources and unnecessary dust and noise at the same time, which is very unfavorable for dust prevention and noise reduction. It also shortens the service life and maintenance cycle of fans and related equipment, and increases the risk of use. increased maintenance costs

In the case of failure of individual ambient temperature acquisition modules, the cooling system will be completely paralyzed, causing unnecessary losses to users

Based on the control of the average temperature of the multi-processors in the controller based on the display screen, the failure state caused by the abnormality of a single temperature collection point can be avoided. However, for large-scale equipment, the temperature rise of one collection point will cause the corresponding The speed of the fan is pulled up

However, areas with low local loads will still get higher fan speeds than they require, resulting in excess heat dissipation, which is detrimental to energy saving, noise reduction and dust prevention
