Operation of integrated electronic security systems in a distorted railway electromagnetic environment – selected security aspects

This research paper reviews issues associated with identifying the impact of electromagnetic interference (EI) sources within an environment where integrated electronic security systems (IESS) are operated. IESS are operated under diverse environmental conditions. They are exposed to internal and external EIs both natural and artificial. The authors conducted experiments within a natural environment. They enabled identifying these interference sources. The outcome of field environmental tests, followed by the modelling of an IESS reliability and operation process was a conclusion that there are methods to minimise encountered EIs. The application of technical solutions within internal IESS structures increases the probability of a system remaining in a state of full fitness. The considerations in this article allowed to develop a method to assess the impacts of EIs on IESS. This method can be successfully employed to examine the operation process in other electronic systems and devices.
