Assessment of the technical condition of the power supply of electronic airport security systems in the aspect of electromagnetic disturbances

Airports are classified as national critical infrastructure facilities mainly due to their strategic importance. Therefore, they require special protection for their functioning. These systems are not only influenced by factors related to the intensity of use but are also exposed to the influence of external and internal, natural and artificial electromagnetic disturbances. For the selected electronic security system (ESS) of the airport, a graph of relations in the system in terms of reliability and operation will be developed. Subsequently, it will enable mathematical analyses to obtain a system of equations describing the system. The obtained results of the reliability and operational analysis of the selected airport ESS, taking into account electromagnetic disturbances, made it possible to estimate the probabilities of the system being in the selected states. The introduction of the factor describing the level of the impact of electromagnetic disturbances on ESS allows for estimating the effectiveness of various solutions counteracting such interactions' effects. The presented reliability and operational analysis of the selected electronic security system used to protect the airport allowed us to estimate its most important reliability and operational parameters. The obtained dependencies make it possible to compare various electronic security systems solutions and select rational solutions for airport security.
