Abstract

The embodiment of the invention provides a system and method for testing the electromagnetic disturbance of a rail transit vehicle to an external environment. The system comprises a loop antenna which receives a magnetic field strength signal of the rail transit vehicle to the external environment and transmits the magnetic field strength signal to a receiver, a double cone antenna, a logarithmic antenna and the receiver. The double cone antenna and the logarithmic antenna receive an electric field strength signal of the rail transit vehicle to the external environment and transmit the electric field strength signal to the receiver. The receiver receives the magnetic field strength signal and the electric field strength signal in a quasi-peak detector mode, tests the electromagnetic disturbance of the rail transit vehicle under a static working condition to the external environment. In a spectrometer peak detector mode, the magnetic field strength signal and the electric field strength signal are received to test the electromagnetic disturbance of the rail transit vehicle under a dynamic working condition to the external environment. According to the invention, the static working condition test and the dynamic working condition test of the rail transit vehicle are realized through the receiver in the quasi-peak detector mode or the spectrometer peak detector mode.

Description

technical field [0001] The invention relates to the technical field of data testing, in particular to a system and method for testing the electromagnetic disturbance of rail transit vehicles to the external environment. Background technique [0002] Many components in rail transit vehicles such as EMUs and urban rail trains (for example, traditional traction systems and auxiliary power supply systems) will generate a large amount of electromagnetic radiation when they are working, and their electromagnetic disturbances to the external environment will affect adjacent rail transit equipment and Therefore, it is of great significance to test the electromagnetic disturbance of rail transit vehicles to the external environment. However, the existing electromagnetic disturbance test system of rail transit vehicles to the external environment cannot realize the static working condition test of rail transit vehicles. Contents of the invention [0003] The embodiment of the prese...
