The Impact

The article presents the results of research electric and magnetic fields in the field of higher frequencies, which are produced by electronic security systems in large logistics areas. The paper also presents the background of the electromagnetic environment. Distorted electromagnetic environment can interfere with the operation of electrical and electronic equipment that are used in the railway area. Particular attention has been paid to the impact of electromagnetic interference on selected electronic security systems.

Abstract The objective of this work is to evaluate the safety of the electromagnetic environment in the carriage of high-speed trains exposed to power cables when the train is full of passengers. The electromagnetic model of a real carriage, two sets of power cables and the 84 passengers were set up by using COMSOL Multiphysics software based on CRH5. The distributions of induced electric and magnetic fields in the carriage, inside and on the surface of passengers were investigated. The results show that the induced electric and magnetic fields on the windows are greater than on the passengers and the max value of induced magnetic field is 2627.10 µT, and the max value of induced electric field is 2.0 × 105 mV m−1. The maximum values of the induced electric and magnetic fields in 84 passengers’ brain tissues were obtained, and it was found that the maximum values occurred in the third row passengers. The distribution of induced electric and magnetic fields at the cross-section of passengers’ heads in the third row was also obtained, and we found that the passengers at the window side were greater than those of aisle passengers. In the third row, the maximum values of the induced electric and magnetic fields in the head of two passengers near the window were 94.6 mV m−1, 90.9 µT, 96.3 mV m−1, and 90.4 µT, respectively. We also found the all data were below the ICNIRP Reference Levels, which indicates the electromagnetic exposure caused by power cables when the train is full of passengers will not threat passengers’ health.
