摘　　要：国内大部分铁路客车使用TCDS系统传输安全监测数据,对列车进行远程监控,轴温报警数据是其中的主要内容。在应用中发现依据轴温报警器所采集的数据用来形成编组还不够准确,同时异常数据也影响了对超温报警的诊断。本文讨论了利用改进编组算法,避免发生多车或少车现象,利用剔除数据纹波和全列环境温度综合评判的方法,消除由异常数据引起的错误报警,旨在提高TCDS系统的易用性和准确性。Most of the railway passenger trains in China use TCDS to transmit safety monitoring data which majors on the remote monitoring and alarming data for axle temperature.During the application,data collected from the alarming device for the axle temperature to define the formation is not exactly and at the same time,abnormal data also affects the diagnosis on the alarming for exceeding the temperature.The artical discusses the calculation for improving the formation to avoid inappropriate quantity of cars and eliminate the false alarming caused by abnormal data by excluding the data ripple and evaluating the environment temperature of the complete train in order to promote the availability and accuracy of TCDS.
