Abstract

The present invention relates to a fan speed regulation method of a display controller, a device and a machine-readable storage medium, wherein the fan speed regulation method of a display controller includes: obtaining the temperature of the working environment and the temperature of the working chip; The fan speed value FanA is determined by the ambient temperature conversion curve; the fan speed value FanB is determined by the working chip temperature conversion curve; the fan speed is determined by comparing the difference between the fan speed value FanA and the fan speed value FanB with the fan adjustment gear value Fanmax / 10 value; adjust and store the fan speed value. The controller for the display screen is divided into areas, and the data of the working environment temperature and the working chip temperature are collected and calculated respectively, and the speed is controlled to improve the efficiency of the fan, improve the heat dissipation effect, improve the service life of various equipment in the controller, save energy, Reduce fan noise and dust.

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
