基于列控系统需求进行的多车仿真研究,是构建完备的列控仿真与功能测试环境的基础环节。本文针对列控系统多节点、分布式的特点,设计基于HLA的列控系统多车仿真方案,提出两种多车仿真策略。根据不同的仿真策略构建基于HLA的多车仿真联邦的逻辑模型和高层仿真模型。对采用不同仿真策略实现的多车仿真联邦进行性能测试,实验结果表明多辆仿真车整体作为一个联邦成员加入仿真联邦的策略更适用于多车仿真,该仿真策略能够满足列控系统中多车仿真的需求。
Research of multi-train simulation based on requirements of the train control system is the groundw- ork to establish a complete platform for simulation and functional verification of the train control system. In the light of features of the train control system being multi-node and distributed,the method of HLA-based multi- train simulation of the train control system was proposed and two simulation strategies were elaborated in this paper. According to the different simulation strategies, both the logical model and high level simulation model of HLA-based multi-train simulation federation were built up. The performance of multi-train simulation federations was tested corresponding to different simulation strategies. The experiment results show that the strategy, in which multiple simulated trains are treated as one whole federate, is more suitable for multi-train simulation and it meets the demand of multi-train simulation of the train control system.
