The research on electromagnetic compatibility and the methods, technologies, theories, instruments and equipment, management systems, and test environment developed therefrom has always been a hot spot of people’s attention. From the initial development to today, electromagnetic compatibility has become a comprehensive new discipline. Compatibility issues have penetrated into various fields of human science and technology, production, military, and life along with the wide application of electromagnetic energy. It should be said that the various benefits that human beings currently enjoy brought to people by high technology are inseparable from the efforts made by human beings in electromagnetic compatibility research for decades. At present, many electromagnetic interference problems are still plaguing and restricting people's production and life. The electromagnetic compatibility problem will become more and more serious and more complicated, and it will be paid more and more attention and research by people. In the future development, the main There are several important development trends as follows.
1. Equipment or system data collection automation. Data mainly refers to the data obtained in the aspects of testing, appraisal, and measuring equipment. In the past, it was used to characterize a single electromagnetic interference parameter. In the future, it will develop towards integrated parameters, that is, collecting, sorting and processing these data with a variety of sensing and measuring methods. The use and measurement system will be further automated in the process of continuous improvement and modification, so that the system can quickly determine and process multiple parameters.
2. Development of equipment and system evaluation technology. Since the electromagnetic compatibility technology is multi-dimensional consideration, diverse analysis, multi-directional settings, multi-parameter processing, and multi-machine or system joint design, it is impossible to evaluate electromagnetic compatibility based on the quality of a certain parameter and the quality of a certain performance index alone. . Of course, parameters such as sensitivity and vulnerability have the connotation of comprehensive performance.
3. Design proceduralization and automation. The electromagnetic compatibility design of the system is a complicated process, and its design must be attached to the functional tasks of the electronic equipment or the system itself. When the research on the electromagnetic environment, electromagnetic interference, and interference control system reaches a considerable level, the programming and automation of the design can be gradually realized. Test instruments such as Electrostatic Discharge Generator, Lightning Surge Generator, Pulse Group Simulator, etc.
4. Electromagnetic compatibility and electronic countermeasures promote and develop each other. Broadly speaking, electromagnetic compatibility is the reflection of technical research from the psychology of avoiding electromagnetic interference, and electronic countermeasures are the technical reflection of the mind to combat electromagnetic interference and intercept electromagnetic signals. Both technically and theoretically have the possibility to learn from each other, thus promoting the deepening of the understanding of the electromagnetic environment.
5. Continuous strengthening of electromagnetic compatibility education. Electromagnetic compatibility is a fringe science involving multiple disciplines, and has now developed into an independent discipline. However, electromagnetic compatibility education has not kept up with the demand. Countries in the world, including industrially developed countries, generally feel that there is a shortage of electromagnetic compatibility professionals.
6. The development of other new technologies will certainly promote the development of electromagnetic compatibility. With the continuous development of science and technology, the development and application of various new technologies will pose new challenges to electromagnetic compatibility. For example, advanced materials, especially synthetic materials and polymer materials, are widely used in household appliances and electronic equipment due to their importance, lightness and ease of assembly. However, it is difficult to maintain good electrical connections at the gaps and interfaces, which reduces the shielding effectiveness. The use of synthetic material instead of aluminum for the aircraft shell is severely damaged when it is struck by lightning due to its poor electrical conductivity. Advanced semiconductor devices on the one hand increase the density of components, on the other hand speed up the operation, and implement low-energy drive, which may bring new electromagnetic compatibility problems.
The development of production technology, medical equipment and diagnostics may enable people to obtain a better explanation of the mechanism of electromagnetic fields affecting the human body. Once the relationship between the frequency and power of electromagnetic fields and ecological effects is understood, electromagnetic fields can be used more safely and effectively. energy.
