Multi-parameter collaborative test method for electromagnetic radiation of rail vehicle

Abstract

The invention discloses a multi-parameter collaborative test method for electromagnetic radiation of a rail vehicle, and relates to the technical field of rail transit electromagnetic compatibility tests. According to the method, a straight rail section is selected for arrangement of a set of ground receiving control system, two sets of position sensing sensor systems are symmetrically arranged atpositions with a distance of L to two sides of a test antenna, a set of on-board measurement and display system is arranged in each of driver's cabs of heads at both ends of the rail vehicle; the on-board measurement and display systems obtain speed and acceleration of the rail vehicle in real time to achieve real-time communication between measured data and the ground receiving control system, and a display interface guides a driver to operate; the position sensing sensor systems provide position information of the rail vehicle, sense a position where the head arrives, and inform the on-board measurement and display systems of the position information through a wireless communication unit; the ground receiving control system realizes test flow setting and measurement and data storage anddisplay of the electromagnetic radiation of the vehicle. The method realizes dynamic tests of each compartment, and facilitates diagnosis of the problem of excessive electromagnetic radiation.

Description

Technical field [0001] The invention relates to the technical field of rail transit electromagnetic compatibility testing, in particular to a method for multi-parameter coordinated testing of rail vehicle electromagnetic radiation. Background technique [0002] Modern rail vehicles integrate huge and complex electrical, communication and signal systems. The electromagnetic radiation generated by the vehicles is an important test item for product type tests. According to the relevant standards for electromagnetic compatibility of rail vehicles, static and dynamic electromagnetic radiation tests on the vehicles are required in the electromagnetic radiation test to determine whether the maximum electromagnetic radiation generated by the train meets the standard requirements. The static electromagnetic radiation test is carried out under the condition that each carriage and the test antenna are stationary. The position is adjusted and the test is easier to carry out. The dynamic ope...
