Abstract

A high-speed railway GSM-R network dynamic detection method and system mainly solve the dynamic real-time detection and real-time analysis of a high-speed railway GSM-R network state and can realize hidden danger analysis of the sudden anomaly of the GSM-R network. The system integrates a traditional independent instrument test system (instrument, test train) into multiple test circuit board detection modules that are installed separately on high-speed trains operating normally, achieve long-range dynamic testing by using a wireless network so that a maintainer can easily determine and analyzewhether base station parameters is reasonably designed and can timely find out the system problems in a network optimization phas to ensure the normal operation of a GSM-R system. The method and system can combine the detected GSM-R network environment information with train control information, and transmit data to the ground through the GPRS and GSM-R wireless transmission technologies, and realize the real-time dynamic monitoring of the GSM-R network where a running train is located.

Description

technical field [0001] The invention belongs to the application field of railway communication monitoring, and in particular relates to a dynamic detection method and system for a high-speed railway GSM-R network during the operation of an EMU. Background technique [0002] The Global System for Mobile Communications–Railway (GSM-R for short) is a digital wireless communication system based on the GSM platform specially developed for railway applications. As a wireless communication system, GSM-R's coverage affects its performance indicators and network operation quality. Unreasonable coverage will cause the indicators to fail to meet the system requirements, and even lead to normal communication failure in severe cases. As a special industry, the railway has high requirements on the safety and reliability of communication. The normal operation of the GSM-R system is of great significance to ensure the safety of trains. [0003] For high-speed railway GSM-R network testing...
