摘要

当前我国高速动车组网络控制系统主要有总线式和交换式2种通信方式，但某些特殊情况下，同速度等级2种通信模式的车型需要实现互联互通。由于2种网络控制系统技术特性和工作原理不同，实现互联互通存在困难，为此提出了一种高速列车总线式与交换式网络控制系统重联方案，包括列车网络拓扑方案、自适应重联策略、初运行过程实现和互联互通控制等，并在“复兴号”高速动车组上进行了验证。验证结果表明，该方案能够实现2种不同通信类型的列车的互联互通控制，对提高列车运营效率具有非常重要的现实意义。

Abstract

At present, there are mainly two communication modes in network control system of high-speed EMU in China: bus-type and switched-type. In some special cases, the two communication modes trains with the same speed grade need to realize connectivity. However, there are some differences between these two kinds of network control system, such as technical characteristics and working principle, the connectivity of this two systems is difficult. Therefore, a reconnection scheme of bus and switched high-speed train network control system was proposed, including train network topology scheme, adaptive reconnection strategy, initial operation process realization and connectivity control, etc., and verified on Fuxing EMU. The verification results show that the scheme can realize the connectivity control of different communication types of trains, which has a very important practical significance to improve the efficiency of train operation.
