Computational Model for the Safe Distance of On-board ATP

安全防护距离的计算模型是车载ATP(列车自动保护)的关键技术之一。影响车载ATP安全防护距离的因素包括列车位置不确定因素、ATP设备反应时间、列车制动性能等。分析了这些因素与安全防护距离之间的关系,建立了移动闭塞系统和准移动闭塞系统的ATP安全防护距离的计算模型。仿真结果表明,计算模型与实际工程数据存在较小的误差,模型具有一定的实际应用价值。

Computational model for the safe distance of onboard ATP is one of the vital technologies, while factors influencing the safe distance include uncertainly train position, reaction-time of ATP equipment and train braking capability,etc. This paper analyzes the nexus of safe distance and the effective factors,establishes a computational model of safe distance for moving block system and quasi-moving block system. The simulation has proved that the computational result and the data of practical project have a smaller margin of error, therefore this model has some practical applications value.
