铁路区间信号系统测试评估平台是对铁路区间列车运行安全控制和防护系统进行可靠性、安全性测试及评估的平台.区间信号设备与列车运行仿真子系统是平台的一个子系统,它为平台提供了一个虚拟的现场环境.采用面向对象技术和离散事件仿真技术对仿真子系统进行了研究.详细地阐述了信号设备及列车的仿真模型、设计和仿真算法,并给出仿真实例,满足平台对仿真子系统地要求.

The testing and assessment platform for railway section signal system is designed to test and assess the reliability and safety of train control and protection system in railway sections. As one part of the platform, the subsystem of signal equipments and train-running simulation provides a virtual scene environment for the platform. With the application of object-oriented modeling (OOM) and discrete event simulation techniques, the simulation models of signal equipments and train-running are established, and simulation algorithm and design method are discussed in detail in this paper. The example given at the end of this paper shows that the simulation subsystem has met the demands of the platform.
