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。
The multi-vehicle simulation research based on the requirements of train control system is the basic part of building a complete train control simulation and function test environment. In this paper, according to the multi-node and distributed features of the train control system, a multi-train simulation scheme based on HLA-based train control system is designed. Two multi-vehicle simulation strategies are proposed. According to different simulation strategies, the logic model and high-level simulation model of multi-vehicle simulation federation based on HLA are constructed. The performance test of multi-car emulation federation with different simulation strategies is carried out. The experimental results show that the multi-car simulator as a federal member joining simulation federation is more suitable for multi-car emulation. The emulation strategy can meet the needs of multi- Simulation needs.
