铁路车辆运行安全监控系统(5T系统)优化方案研究

Study on Optimization of Running Safety Monitoring System of Railway Rolling Stock

在阐述铁路车辆运行安全监控系统?(5T?系统)?既有功能和架构的基础上,分析系统性能和功能上存在的问题。为了解决性能问题,研究一种基于数据库日志分析的数据同步方法,基于此方法,提出数据同步与数据库读写分离的优化方案。针对功能上的问题,利用数理统计、信息整合等技术,提出?TPDS?和?TADS?报警联网监控与?THDS?热轴综合报警的解决方案。通过对?5T?系统进行优化,解决系统服务器资源紧张带来的各种问题,提高报警信息的利用率和准确率。

This paper analyzes functions and problems of existing running safety monitoring system of railway rolling stock（i.e. 5T for THDS、TADS、TPDS、TFDS and TCDS）, and in order to solve performance problem, a data synchronization method based on database log analysis was studied, based on which an optimization program of separating data synchronization with database read/write was put forward. As to functional problems, a solution combining TPDS and TADS alarm networking monitoring with THDS hotbox alarm was proposed based on technologies like mathematical statistics and information integration Through optimizing 5T systems, all kinds of problems caused by tense resource of system server were solved and the utilization rate and accuracy of alarm information were promoted.
