避难线设置检算系统研究

Research on the Inspection System of Refuge Siding Setting

避难线是防止失控列车超速颠覆或与区间其他列车冲突而设置的保障列车安全运行的特殊线路。在铁路技术条件发生变化的基础上,传统的人工检算办法具有工作量大、精度低的特点,已不能满足现有铁路技术要求。本文旨在利用C#语言开发一套避难线设置检算系统,提供不同检算办法下的避难线设置检算。首先在长大下坡道受力分析、运行策略等牵引计算理论的基础上,建立检算系统的数学模型,确定系统的工作过程;再进行检算系统的功能分析与数据库设计;最后以宝成铁路宝鸡至秦岭段作为案例,检算该条长大坡道设置避难线的必要性。

Refuge siding is a special line that ensures the trains to operate safely, preventing subversion of runaway trains or conflict with other trains in a same section. On the basis of the change of railway technology conditions, the traditional manual inspection approach has the characteristics of heavy workload and low accuracy, and it cannot meet the requirements of existing railway technology. The paper aims to develop a computing system about refuge siding setting by using C＂ language. The system can inspect refuge siding setting by using different inspection approaches. First, on the basis of the train traction calculation theories, such as stress analysis of long slope, execution policy etc., a mathematical model of check calculation system was established, the working process of the system was determined. Secondly, the system was developed and the database was designed. Finally, takingBaoji to Qinling section as an example the necessity of setting refuge siding in this case was inspected.
