车载ATP系统是保证列车运行安全的系统,其中的关键技术之一是安全制动曲线计算模型.根据IEEE 1474.1TM标准的规定[1],车载ATP安全制动曲线由GEBR制动曲线和ATP紧急制动触发曲线组成.GEBR制动曲线是根据GEBR计算得出的,而ATP紧急制动触发曲线则是根据GEBR制动曲线计算出来的.针对该问题,本文分析了各种影响列车制动距离的因素和GEBR制动曲线与ATP紧急制动触发曲线的关系,建立了CBTC率载ATP安全制动曲线的计算模测.仿真证明,本文提出的计算模型满足IEEE 1474.1TM基于CBTC的车载ATP安全制动模型的要求.%The onboard ATP system is the system which protects train running safety. One of its key technologies is the computational model of the safe braking curve. According to IEEE 1474.1?, the on-board ATP safe braking curve is made up of the GEBR braking curve and the ATP emergency brake triggering curve. The GEBR braking curve is calculated by GEBR and the ATP emergency brake triggering curve is calculated by the GEBR braking curve. This paper analyzes various factors influencing the train braking distance and the relationship between the GEBR braking curve and the ATP emergency brake triggering curve, and establishes the computational model of safe braking curve of onboard ATP based on CBTC . Simulation proves that the model of this paper satisfies the IEEE 1474.1? Requirements for the safe braking model of onboard ATP based on CBTC.
