Abstract

The paper presents issues associated with the impact of electromagnetic interference on track-side cabinets of a closed-circuit television system (CCTV) functioning in a railway transport environment. The measurements of an electromagnetic field emitted by a track-side CCTV cabinet were presented. Designs of this kind are operated in railway facilities; therefore, they should not disturb the functioning of other equipment, the rail traffic control systems, in particular (the so-called inner compatibility). An analysis of the obtained results facilitated developing a research model, and, further, improving its reliability and conducting an operational analysis, considering electromagnetic interference. This enabled us to determine a relationship allowing us to specify the probability of a track-side CCTV cabinet staying in a state of full ability. The presented discussions regarding a track-side CCTV cabinet, considering electromagnetic interference, allow us for the numerical assessment of different types of solutions (technical and organizational), which can be implemented in order to mitigate the impact of electromagnetic interference on the system functioning.
