Abstract

The invention belongs to the technical field of system noise reduction, and discloses a computer system noise reduction method and system based on an intelligent chip. The computer system noise reduction system based on the intelligent chip comprises a noise and sound information acquisition module, a sound information conversion module, a noise signal acquisition module, a central control module,a noise signal detection module, a signal analysis module, an analog-to-digital conversion module, a noise reduction processing module and a stable output module. The active noise reduction technology is adopted through the noise signal detection module, and the purpose of screening out low-frequency noise signals from the noise signals is achieved; through the analog-to-digital conversion module, high-precision analog-to-digital conversion can be guaranteed, and meanwhile, the size and the production cost of the analog-to-digital converter are greatly reduced; the noise reduction processingmodule suppresses noise signals with small amplitude in the image signals and eliminates alternating voltage in the pulse voltage, so that the pulse voltage becomes smooth direct voltage, harmonic interference of a circuit can be avoided, and the noise reduction effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of system noise reduction, and in particular relates to a computer system noise reduction method and system based on an intelligent chip. Background technique [0002] At present, the level of computer system noise is one of the important intrinsic qualities of a computer system. It is a dilemma in computer system design to satisfy the cooling requirements of the system and obtain a low-noise system. When actual users use the computer system, the load of the system is less than 50% in more than 90% of the time, and, in most usage environments, the temperature and humidity of the air do not reach the highest design index of the computer system. [0003] Existing technologies mostly use a combination of software and hardware to reduce system noise. Once the software senses that the system is under low load, it starts the hardware control device and reduces the fan speed. However, the biggest disadvantage of ...

Problems solved by technology

[0004] Through the above analysis, the problems and defects of the existing technology are: the existing method of reducing system noise based on the combination of software and hardware will occupy system resources for a long time, and once the software fails, such as virus infection or system crash Unable to monitor; at the same time, the combination of software and hardware temperature control technology still has disadvantages such as low accuracy, slow response speed and inflexible control strategy
