列控数据完备性建模方法研究

Research on modeling method for data completeness of train control

列控数据作为列车运行控制的基础,是列控系统的中枢神经,其完备性直接关系到列车运行安全。列控数据完备性能够保证列车安全控制数据的完整性、正确性、有序性、实时性、有序性和兼容性。本文以CTCS-3级列控系统和CTCS-2级列控系统之间的等级转换以及典型的设备故障导致降级场景为例,利用随机Petri网建立列控数据完备性模型,重点研究了列控数据完备性的完整性、实时性和兼容性方面的问题,最后提出了用模型完成的成功率以及系统平均延时时间分析列控数据完备性的方法。

Control data was the basis for the control of the train operation and was the central nervous of Train Control System,its completeness directly related to train operation safety.The completeness of control data referred to the integrity,correctness,orderliness and real-time,timeliness and compatibility,which could ensure train operation safety.This article took level transform between CTCS-3 and CTCS-2 as well as the degraded situations caused by typical equipment faults as an example and focused on the completeness of train control data integrity,timeliness and compatibility issues.This paper used the stochastic Petri Net to establish the completeness of control data model and proposed analysis method of data completeness by the successful probability.
