动车组网络控制系统及技术分析

Analysis of EMU's Network Control System and Technology

摘要:

动车组的网络控制系统相当于人的大脑和神经,它在保证列车的行车安全、可靠性、舒适性方面具有至关重要的作用;为了给相关产品的网络控制系统设计提供借鉴,通过梳理中车已有典型动车组产品的网络控制系统,提取共性特征,总结归纳了动车组网络控制系统的组成、系统功能、拓扑功能、主要参数等内容;同时,乘客需求的提升以及轨道交通装备技术的不断升级,对动车组在速度、舒适性、智能化等方面提出了更高要求,为了明确动车组列车网络控制系统的发展方向,通过查询专利文献等途径,得出动车组网络控制系统新技术研究多集中在多网融合、列车冗余优化设计、列车自动驾驶、无线通信等方向,可以为轨道交通技术特别是网络控制系统技术的相关研究提供参考。

Abstract:

The working of EMU network control system corresponds to that of the human brain and nerves. Itplays a critical role in ensuring the EMU'ssafety, reliability, and comfort. In order to provide reference for the design of the related network control system, by analyzing CRRC's main EMU products and extracting their common features, the key elements of the EMU's network system have been described, such asits structure, the system function, the topological function and its main parameters.Meanwhile, the promotion of passenger demand and the continuous upgrading of rail transportation equipment technology, areputting forward higher requirements tothe EMU's speed, comfort and intelligence.In order to clarify the development directionof EMU's network control system, through querying the patents and literatures, the new technology research on EMU network control systemis also considered, which is focused on the multi-network convergence, the optimization designof train redundancy, train automatic driving, wireless communication and so on. This can provide reference for the design of the train's network systemtechnical research.
