Method and device for measuring external electromagnetic radiation of train and electronic equipment

Abstract

The invention provides a method and device for measuring the external electromagnetic radiation of a train and electronic equipment. The method comprises the steps that at a first position of a train, near-field electromagnetic radiation data of a target line corresponding to the train are measured along with running of the train; and based on a preset conversion algorithm, the measured near-field electromagnetic radiation data, corresponding to the target line, of the train are converted into external-field electromagnetic radiation data, wherein the external-field electromagnetic radiation data are used for evaluating the electromagnetic radiation influence generated by the train on the external environment in the process in which the train travels on the target line, the conversion algorithm is determined based on a mathematical relationship between the near-field electromagnetic radiation data of the train measured at the first position and the external-field electromagnetic radiation data of the train measured at a second position of the target line at the same moment, and the second position is an external environment measurement position conforming to train electromagnetic radiation compliance detection and does not change along with train running.

Description

technical field [0001] This document relates to the technical field of data processing, in particular to a method, device and electronic equipment for measuring electromagnetic radiation outside a train. Background technique [0002] In recent years, high-speed railways have developed rapidly in my country, and more and more types of trains are operating across the country. The train adopts 25KV AC power traction power supply system, and the spark discharge caused by the traction motor and pantograph-catenary offline will generate electromagnetic interference. In order to control the impact of electromagnetic interference generated by train operation on surrounding sensitive electronic communication equipment, the country has clear requirements for electromagnetic radiation limits. For this reason, it is necessary to measure the electromagnetic radiation generated by the running of the new line to verify whether the external electromagnetic interference of the train running...

AI Technical Summary

Problems solved by technology

This method needs to set up a large number of detection positions for long sections of the line, so it consumes a lot of material and manpower

In addition, the effective time for a fast-moving train to pass the detection position is less than 0.1s, making it difficult to capture electromagnetic radiation data at all frequency points, resulting in high deviations and limitations in measurement results
