CTCS-3级列控系统ATP超速防护曲线的仿真

Simulation of ATP Overspeed Protection Curve Based on CTCS-3 Train Control System

CTCS-3级列控系统的核心——ATP自动防护系统,它生成的目标距离模式曲线实现了由对地面固定信号显示的控制到面向列车移动体直接控制的转变,为高速铁路时代的列车提供安全保障。本文以ATP仿真系统为研究对象,提出用硬件与软件相结合的方法模拟仿真CTCS-3级列控ATP控车曲线,对制动曲线进行建模,分析及计算,完成ATP仿真系统模型的建立、数据的采集以及模型参数的分析。

The core of the CTCS-3 is ATP automatic protection system. In order to assure operation safety of high-speed railway,the distance-to-go model curve of ATP realizes the changes of the trackside fixed signal turning to the direct control of moving train. This paper takes the ATP simulation system as the research object,the paper put a method that by combining the hardware and software to simulate the generation of the ATP CTCS-3 train’s control curves and divides the simulate system in function and modular.Combining theory and research methods,it also carries out the ATP simulation system for modelbuilding,data collection and analysis of model parameters.
