PROBABILISTIC METHOD FOR RATIONING OF EMC OF RAILWAY AUTOMATICS
[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The scientific and technical problem of rationing of noise immunity level and rigidity of tests of railway automation and telemechanics is considered. The problem remains topical in connection with the widespread introduction of microprocessor and computer automation systems that ensure train traffic safety. The task is to find the norms of noise immunity on the basis of taking into account the probabilistic nature of the level of interference and the level of noise immunity of the hardware element base. The «load-stability» method was used to obtain equations for determining the normalized value of noise immunity. The norms calculated by the proposed method allow optimizing rigidity of tests and associated design solutions. Keywords: railway, automation and telemechanics systems, electromagnetic compatibility, rationing, probabilistic approach, test methods, probability of failure, train traffic safety.
