Research on Wireless monitoring and Health Assessment System for High-speed Train Operation and Maintenance Status

本文主要是研究高速列车运维状态无线监测与健康评估系统。首先根据实时采集的列车状态信息和故障信息类型多元化的特性,实现多类型数据的优化融合,然后通过构建的(3G/4G/WLAN/北斗)多模式网络完成数据传输,并解决多模式通信网络协议的兼容性以及不同网络的无缝切换。最后采用“改进的Barthel指数评分机制”构建高速列车健康状态评估体系,为列车的维护和故障预警、诊断提供参考标准,从而保证高速列车的运营品质和运营速率。

This paper mainly studies the wireless monitoring and health assessment system for high-speed train operati on and maintenance status.First,accord in g to the diversified characteristics of the real-time collected train status information and fault information types,it realizes the optimal integration of multiple types of data,and then completes the data transmission through the(3G/4G/WLAN/Beidou)multi-mode network,and solves the compatibility of the multimode comm un icati on ne twork protocol and the seamless switching of different ne tworks.Fin ally,the"improved Barthel index scoring mechanismw" is used to build a high-speed train health assessment system,which provides referenee stan dards for train main tena new,fault early warning and diag no sis,so as to en sure the operati on quality and speed of high-speed trains.
