近年来,随着我国高速铁路快速发展,联调联试工作伴随其同步快速发展,信号系统动态检测是联调联试的重要内容之一,是一种功能性验证,是对信号系统软件主要功能、各子系统间接口关系、数据准确性和一致性的检验.针对联调联试信号系统中发现的问题类型和数量进行统计分析并给出相关建议,为今后高速铁路设计、施工安装、软件编制、数据配置以及检测等方面的工作提供一定帮助和借鉴.此外,对信号系统大数据挖掘工作也能提供有力支持.
The preparation and management of train control system dynamic detection program proceed throughout the entire high-speed railway train control system dynamic testing, from the preparation of the pre-test plan, the test process plan modification, and to the test program statistics and query. The traditional program management approach to manage dynamic detection sequence tends to be scattering and not easy to inquire. This paper presents a high-speed railway train control system based on dynamic detection program management support tool Excel VBA with very powerful statistics and data processing capability to fulfill such functions as addition, delete, change, check, verification and output of the dynamic testing program. The validity and reliability of the program management support tool are proved by practices.
在区域联锁主控站,车务人员无法实时观察被控站道岔动作情况,这给行车带来安全隐患.为此设计了一套电流表远程监测系统以解决此问题,本文对系统的结构、系统功能及采用的关键技术进行了论述.
采用传统人工查找方法进行高速铁路联调联试动态检测序列的生成,需要的工作量大,且不稳定,容易冗余或者缺少进路序列.依据Excel具有的非常强大数据处理能力,提出了利用Excel VBA自动生成高速铁路列控系统动态检测序列,并通过实例应用,验证了Excel VBA编程的有效性与实时性.
在编组场设置停车器,可以提高调车作业效率,保证调车人员人身安全.此项研究是在计算机联锁系统的基础上开发停车器控制软件,包括软件需求分析和软件设计.在需求分析时,结合场景和图形对自动控制的需求进行分析;软件设计活动设计了基于面向对象的停车器模块,以及软件的总体架构.同时,通过对停车器模块进行建模,重点分析了停车器关联控制区段的算法,以及根据电源屏供电情况,停车器动作数量的算法.采用面向对象的设计方法不仅有助于软件模块化,同时减少对原有程序的影响,提高联锁软件的正确性和安全性.
According to the integrated navigation system which consists of inertial navigation system(INS) and odometer,the cross calibration of INS and odometer were achieved by estimating the biases of inertial sensors,scale factor of odometer,and attitude error between INS and odometer in real-time.The above tasks were resolved by a closed-loop Kalman filter,which can easily use the estimates to compensate INS and odometer.An integrated supervisory system was constructed to detect and isolate the bad data when a vehicle run in a complex environment.It helps to improve the accuracy of navigation system.
