Abstract

The invention provides an electromagnetic radiation emission real-time measurement system for a high-speed train and relates to the technical field of the wireless electric signal and electromagnetic radiation emission measurement and the interference source positioning. The system comprises a vehicle-mounted measurement subsystem, a ground measurement subsystem, a vehicle-mounted vehicle positioning subsystem and a vehicle ground wireless transmission subsystem, wherein the vehicle-mounted measurement subsystem is used for carrying out real-time statistical parameter measurement on the electromagnetic interference inside a high-speed train vehicle by a multi-channel measurement receiver, extracting and classifying the electromagnetic interference with different characteristics and positioning source equipment emitting the electromagnetic interference inside the vehicle by the mode identification; the ground measurement subsystem is used for measuring real-time electromagnetic radiation emission signals by the multi-channel measurement receiver and filtering interference signals in the real-time electromagnetic radiation emission signals, which are from the outside of the high-speed train by utilizing blind signals; the vehicle-mounted vehicle positioning subsystem is used for acquiring real-time position and speed information of the high-speed train vehicle by utilizing a GPS (Global Positioning System) cooperative positioning technology; and the vehicle ground wireless transmission subsystem is used for implementing the time and space synchronization between the vehicle-mounted measurement subsystem and the ground measurement subsystem.

Description

technical field [0001] The invention relates to the technical fields of radio signal, electromagnetic radiation emission measurement and interference source location, in particular to a real-time measurement system for electromagnetic radiation emission of high-speed EMUs. Background technique [0002] With the development of high-speed railway, the electromagnetic compatibility of high-speed EMU equipment has become one of the key factors that directly affect its operation safety. Many major accidents in recent years have shown that if the electromagnetic compatibility performance of high-speed EMUs is poorly designed or fails to meet the required standards, key equipment in the system may fail due to electromagnetic interference, causing catastrophic consequences. [0003] Electromagnetic radiation emission measurement of electrical and electronic equipment is one of the main technical means to study the interference and anti-interference and electromagnetic compatibility ...
