Abstract: The operation of transport security systems, e.g., intrusion and hold-up alarm systems (I&HAS), in a large railway area is exposed to the influence of electromagnetic interference. Electromagnetic disturbances are generated by intentional or unintentional, stationary or mobile sources of interference. The level of generated electromagnetic disturbances affects the safety process of operating systems, e.g., railway traffic control systems, transport security systems. The generated interference can cause an alarm state in a transport security system, which may result in stopping train traffic, calling security services, announcing an evacuation – that is, the occurrence of measurable financial losses. This paper presents an assessment of the operational safety of transport security systems affected by electromagnetic interference.1. INTRODUCTION
In the 20th century, as a result of human activity, artificial factors shaping the electroclimate were introduced. Due to the emergence of countless sources of radiation, serious changes have occurred in the Earth’s electromagnetic environment.
Widespread interest in the adverse effects of electromagnetic fields, from various frequency ranges, on the human body and the operation of electronic devices (…)
