Electromagnetic Compatibility Of ECG And Testing Research

Along with the modern science technique development, quantity and category electronics equipments continuously increase, space electromagnetic wave the segment continuously expand, and make the electromagnetism environment increasingly complicated. In this kind of complicated electromagnetism environment, the electronics system may suffer the influence of the electromagnetism interference maybe deviate the normal work appearance, even appears to paralyze the appearance.We say that these equipments are electromagnetisms, when the electronics equipments noise or the electricity equipments has an effect other equipments and be free from other equipments interferences. Also is to say under the condition of the space, time and the frequency chart resources etc. of the limit, various electric equipments can coexist, don't cause the degradation of the function.Developed counties throw large quantity's manpower, material resources on the research of EMC. They issued some laws concerning EMC, with communication, calculator, and every kind of medical treatment equipments etc. The science technique that our country research EMC, compare with the other, behind schedule the abroad more serious. The Certification and Accreditation Administration of the People's Republic of china in the December of 2001 issued 《the rule of compulsively product of the certification the management》 and 《the first catalogue of that into practice certification of compulsively product》 .There is just we usually hear of 3 C certification. But compared with the electromagnetism domain in china over the country, the medical equipment technique foundation is very weak. Enhance the Electromagnetic Compatibility of medical treatment research, increase the equipment's anti- interference the ability, and decline the lowest degree the risk of latent electromagnetism interference, this aspects are just put a serious problem in front of us.Research scope of EMC is very extensive and the problem of EMC is very complicated. The EMC testing technology is one focus of the EMC research field. The EMC testing processing and result technology includes testing equipment, testing method and data evaluation.This thesis introduce the Electromagnetic Compatibility foundation theories in detail, and combined with the ECG actual application, analysis and study the Electrical fast transient/burst immunity, Electrostatic Discharge immunity, Surge immunity, conducted disturbances, induced by radio-frequency fields immunity. Introduced the homologous test and evaluate methods, the main work as follows:...
