Method for shielding electromagnetic interference of computer and related assembly

Abstract

The invention discloses a method for shielding electromagnetic interference of a computer and related components, after the computer is started up, the computer is controlled to operate in a first optimal SSC mode selected when the computer is started up last time, whether the output frequency bandwidth of a CPU of the computer in the current electromagnetic interference environment is 0 is judged, if yes, it is indicated that the computer is not subjected to electromagnetic interference at the moment, and if not, adjusting the SSC parameter until the adjusted parameter is the SSC parameter which enables the output frequency bandwidth of the CPU to be minimum in the current electromagnetic interference environment, indicating that the electromagnetic interference suffered by the computer at the moment is minimum, and setting the SSC parameter at the moment as a second optimal SSC mode so as to control the computer to operate in the second optimal SSC mode. According to the method, hardware does not need to be added, electromagnetic interference shielding of the computer can be achieved only by adjusting the SSC parameters, cost is reduced, and the method is high in portability and suitable for various electromagnetic interference environments.

Description

technical field [0001] The invention relates to the computer field, in particular to a method for shielding a computer from electromagnetic interference and related components. Background technique [0002] In recent years, due to the changing international situation, there is an urgent need for the rapid development of the localization process of the manufacturing industry. The localized PC (Personal Computer, personal computer) has also been developed rapidly. With the rapid development of PC, various test performances have been improved. It is also an important part of its development. At present, the mainstream PC market may still be based on the foreign intelX86 CPU architecture. Although domestic PCs are limited by the design of domestic hardware and the manufacturing technology of domestic components, there may be some slight gaps with the mainstream PC market. However, domestic Zhaoxin PC stands out from the dividends of recent development. In terms of performance, ...

At present, the mainstream PC market may still be based on the foreign intelX86 CPU architecture. Although domestic PCs are limited by the design of domestic hardware and the manufacturing technology of domestic components, there may be some slight gaps with the mainstream PC market. However, domestic Zhaoxin PC stands out from the dividends of recent development. In terms of performance, it can match or even exceed the mainstream foreign advanced PCs, but there may be slight differences in test performance.

[0003] For example, when the PC is tested under the stress test program to test the stability of the PC, since the PC is in the RE low-frequency radiation test environment, the test failure phenomenon will occur during the stress test, that is, the test process will be caused by electromagnetic interference. Failed. In the prior art, in order to avoid the impact of electromagnetic interference on the test results, the design of adding hardware circuits is usually adopted, but the design of adding hardware circuits is expensive, and the main board of the PC itself is already covered with electronic components. Interfering hardware needs to redesign the motherboard, and the redesigned motherboard is not suitable for PCs under different electromagnetic interference environments, that is, the adaptability and portability are poor, and it is not easy to put into use
