Discuss the harm of electromagnetic interference and electromagnetic compatibility technology

       Over the years, the electromagnetic compatibility technology as a whole has shown a trend of rapid evolution, which involves a variety of corresponding methods and technologies. Generally speaking, it is necessary to flexibly choose electromagnetic compatibility technology for comprehensive prevention and control of harmful electromagnetic interference, which typically includes electromagnetic absorption, electromagnetic shielding, system grounding and filtering technology. On this basis, for different types of electromagnetic compatibility technologies, we must focus on a full range of flexible choices, so as to ensure that the electromagnetic compatibility technology can truly serve the comprehensive prevention and control of electromagnetic interference. The editor has compiled the following knowledge for everyone:


       One. Exploring the various hazards caused by electromagnetic interference

       Judging from the status quo, all areas of daily life cannot be separated from electronic equipment. However, it should not be overlooked that the electronic equipment itself will cause prominent electromagnetic interference, so as to harm the most fundamental human health. When the situation is serious, electromagnetic interference will also cause a variety of human diseases and reduce the inherent performance of electronic equipment. Specifically, electromagnetic interference is likely to manifest as the following significant hazards.


       1. Damage to human health

       Due to long-term electromagnetic radiation interference, once the maximum human endurance limit is exceeded, various health damages corresponding to it will be caused. At the same time, electromagnetic radiation can also cause serious health risks and health threats. This is mainly due to the fact that the radiant energy will directly act on specific human organs or human tissues, resulting in a prominent non-thermal effect or radiant heat effect. Under this premise, the comprehensive prevention and control of potential electromagnetic radiation is also protecting human health, which requires wider attention.


       2. The inherent performance of electronic equipment is impaired

       Certain conductive electromagnetic interference will reduce the inherent operating efficiency of electronic equipment, or bring prominent disaster consequences. For example, for a variety of special medical equipment such as high-frequency scalpels or microwave electrotherapy equipment, if such equipment exhibits high-frequency spatial radiation, it is likely to reduce the performance of other equipment nearby. In severe cases, if the electronic equipment is in the same loop, it will present some sudden disasters.


       Two. Characteristics and connotation of electromagnetic compatibility technology

       According to the relevant standards at this stage, electromagnetic compatibility technology should refer to the various sub-systems and various equipment in a specific electromagnetic environment that can maintain a stable coexistence state without detracting from their own executive functions. Specifically, in practice, electromagnetic compatibility technology should usually include sub-systems and certain electromagnetic equipment. The purpose of this type of technology is to ensure that the above-mentioned equipment will not suffer frequent or severe electromagnetic interference, thus degrading its original equipment performance. In addition, the electromagnetic compatibility technology also focuses on preventing and controlling the interference suffered by the surrounding environment to ensure that the above-mentioned electromagnetic interference is controlled within acceptable limits.


       It can be seen that the electromagnetic compatibility technology itself needs to be established under the premise of the three core elements of electromagnetic coupling, electromagnetic interference sources and sensitive equipment. After generalization, it can be seen that the focus of electromagnetic compatibility technology should be to fully clarify the relevant mechanisms of electromagnetic interference sources. , And then give the related prevention and control methods or prevention and control methods accordingly. While focusing on preventing and controlling electromagnetic interference in an all-round way, it is necessary to cut off the various transmission channels accordingly. At the same time, the above-mentioned electromagnetic compatibility technology also needs to deeply analyze the enhancement measures of anti-interference performance and the performance of sensitive equipment. Response methods and other relevant points.
