Abstract
The present invention provides a kind of method reducing Overall Power Consumption and noise in desktop computer of soaring, belong to domestic processor technical field, the present invention uses the method using processor to be automatically switched off and open fan power supply according to system temperature situation in the products-hardware design that domestic Feiteng processor designs, fan can be stopped operating in the case of system temperature is the highest, just power to fan after system temperature reaches certain threshold value and control the heat radiation of its rotating speed, reducing the purpose of Overall Power Consumption and noise.
Description
Technical field
The present invention relates to domestic processor technology, particularly relate to a kind of desktop computer of soaring reduces Overall Power Consumption and noise
Method.
Background technology
Recently as the development of domestic Godson CPU, the product using domestic processor to design has begun to gradually promote,
Desktop computer also begins to progressively apply, but because domestic processor relatively X 86 processor in design technology and performance still has
A little gaps, in order to improve the competitiveness of domestic processor products, need in the design to use certain methods to improve complete machine energy
Loss-rate and reduction noise etc. obtain the accreditation of client.
Summary of the invention
In order to solve above technical problem, the present invention proposes the domestic four core Feiteng processor design desktop computers of a kind of employing
In how to realize the method that ensures to reduce Overall Power Consumption and noise under product stability premise, improve and use the design of domestic processor
The competitiveness of desktop computer product.
The present invention and the desktop computer product of four core processors of soaring to employing, in order to reduce Overall Power Consumption and noise, producing
Product hardware designs uses the method that processor was automatically switched off and opened fan power supply according to system temperature situation so that fan exists
Can stop operating in the case of system temperature is the highest, just power to fan after system temperature reaches certain threshold value and control it
Rotating speed dispels the heat, and reduces the purpose of Overall Power Consumption and noise.
In the desktop computer product using domestic four core processor designs of soaring, because power consumption of processing unit itself is relatively low, treating
As long as heat sink design is the best in the case of machine, fan does not start and will not crash yet, and during mainboard start, fan power supply is to close
, start system temperature inspection software after entrance system, obtain processor and cabinet inside ambient temperature constantly, when discovery processes
When device temperature is not reaching to need to start fan, close processor and complete machine fan power supply respectively all the time by 2 GPIO, when sending out
After existing temperature of processor is increased to uniform temperature, controls 2 GPIO and open fan power supply, and according to current detection temperature conditions control
Rotation speed of the fan processed dispels the heat to processor, after temperature is reduced to a certain degree, is again switched off fan power supply, so reaches energy-conservation fall
The purpose made an uproar, because fan noise is the main source of desktop computer product noise, so can reduce Overall Power Consumption and reduce system simultaneously
System noise.
Temperature sensor uses W83795 and critesistor with fan control chip, and fan power source control circuit uses MOS
Pipe.
The temperature of CPU is obtained less than the startup fan threshold arranged when processor reads W83795 depositor by I2C bus
During value, close fan power supply, when temperature is higher than the startup fan threshold value arranged, open fan power supply, and according to temperature conditions control
Pwm signal processed, obtains rotation speed of the fan by TACH feedback.
The invention has the beneficial effects as follows
Not powered to fan cpu temperature is low when by control fan power supply enable mode allows it not consume any power consumption not
Produce noise, power to fan after temperature exceedes certain threshold value and reach system radiating and complete machine according to temperature controller rotating speed
Power consumption and the conservative control of noise.
Accompanying drawing explanation
Fig. 1 is system flow chart；
Fig. 2 is that system implements block diagram.
Detailed description of the invention
Below present disclosure is carried out more detailed elaboration:
As it is shown in figure 1, fan power supply is to close during mainboard start, start system temperature inspection software after entrance system, constantly
Obtain processor and cabinet inside ambient temperature, when finding that temperature of processor is not reaching to need to start fan, all the time by 2
Individual GPIO closes processor and complete machine fan power supply respectively, after finding that temperature of processor is increased to uniform temperature, controls 2
GPIO opens fan power supply, and dispels the heat to processor, when temperature is reduced to according to current detection temperature conditions control rotation speed of the fan
After to a certain degree, it is again switched off fan power supply.
As in figure 2 it is shown, use the desktop computer of 1500A tetra-core processor exploitation of soaring, temperature sensor and fan control core
Sheet uses W83795 and critesistor, and fan power source control circuit uses metal-oxide-semiconductor, when processor is read by I2C bus
When the temperature of W83795 depositor acquisition CPU is less than the startup fan threshold value arranged, closing fan power supply, temperature is higher than setting
When starting fan threshold value, open fan power supply, and control pwm signal according to temperature conditions, obtain fan by TACH feedback and turn
Speed, it is achieved reduce Overall Power Consumption and noise.
