Description
Technical Field
The invention relates to the field of controllers, in particular to a fan speed regulation method and device of a display screen controller and a machine readable storage medium.
Background
At present, a fan cooling system of a mainstream controller for a display screen generally obtains a collection point temperature by using an ambient temperature collection module. In the prior art, the collection point temperature used for calculation is the ambient temperature in which a single-use device is located, or the temperatures of a plurality of processors in the device are collected and the average temperature of the processors is calculated. The fan rotating speed of the controller for the display screen is controlled through a training curve of the acquisition point temperature corresponding to the fan rotating speed or a conversion table of the acquisition point temperature corresponding to the fan rotating speed according to an empirical value, so that the aim of adjusting heat dissipation is fulfilled.
The environment temperature acquisition module only acquires the environment temperature of the controller for the display screen, and adjusts the rotating speed of the fan according to the temperature, so that all fans of the whole equipment are kept at the same rotating speed of the fan. For display controllers, especially large LED displays, there are typically multiple processor units, corresponding to multiple zone fans. In the prior art, a conversion table from the temperature of the collection point to the rotating speed of the fan can be preset completely according to empirical values, or the ambient temperature of single or multiple pieces of using equipment is used as the temperature of the collection point, the rotating speed of the fan is obtained through simple average calculation, and the rotating speed of the fan of the controller for the LED display screen is controlled. The prior art can not accurately divide the areas of each processor, can not independently control the rotating speed of fans in each area, and can not solve the problem of heat concentration caused by high local load. If all fans operate simultaneously, cause the waste of electric power resource, cause unnecessary raise dust and noise simultaneously, it is very unfavorable to dustproof and noise reduction, also shortened the life and the maintenance cycle of fan and relevant equipment, promoted the use risk, increased the maintenance cost. Under the condition that a certain ambient temperature acquisition module fails, the heat dissipation system is completely paralyzed, and unnecessary loss is brought to a user. The failure state caused by the abnormity of a single temperature acquisition point can be avoided by controlling the average temperature of the multiple processors in the controller based on the display screen, but for large-scale equipment, the rotating speed of the fan corresponding to each regional processor is increased due to the temperature rise of one acquisition point. The areas with low local loads still obtain higher fan speeds relative to their required fan speeds, resulting in excessive heat dissipation, which is detrimental to energy conservation, noise reduction and dust protection.
