Research on the Electromagnetic Interference of the Balise System of High-Speed Train

In the actual railway environment, the working environment of the balise system is faced with all kinds of electromagnetic harassment, and the electromagnetic environment is very complicated. The electromagnetic interference simulation analysis model of the balise system is built, and the coupling mechanism of electromagnetic interference is studied. In this paper, the downlink and uplink antenna simulation models of the balise system are constructed. Then the simulation is verified by feeding the antenna port, the expected simulation effect is achieved. At last, the influence of the crosstalk current at the antenna port of the vehicle balise is analyzed and summarized for different cases by varying the angle of polarization, incidence, pitch and azimuth of the interfering signals at each angle.
