Simulation and Measurement of Multi-source Electromagnetic Environment of Urban Rail Transit Communication Room

The safety of the equipment in the communication room is the basis to ensure the reliable operation of the urban rail transit. Therefore, it is of great significance to investigate the complex electromagnetic field distribution and radiation level in the communication room. On the basis of investigation, the typical interference sources and their transmission routes are explored first. The influence of each interference source on the internal electromagnetic environment is simulated and analyzed, which shows good consistency with the measured.
