基于通信网络机车分布式系统实时控制的分析与研究

摘要

According to the affect on the locomotive control system and real-time requirements via communications network and transmission, and through the analysis of Train Communication Networks' character and application requirement of distributed vehicle control system, the network based disposal of real-time control has been concluded. Based on the analysis of all aspects of the delay causes and effects, focusing on real-time distributed control systems of rail-transport vehicle performance analysis and research, draw on the real-time communication network control system must consider the impact of the network, in particular, the transmission delay impact, while the optimized real-time control principle and method of network based distributed vehicle control system is proposed, at the same time the tested and verified.%针对基于通信网络的机车控制系统实时性要求及网络传输的可能影响,通过对列车通信网络(TCN)技术特点以及车载分布式控制应用要求的分析,总结了基于网络的实时控制的处理;在分析各个环节的延时成因及影响的基础上,重点对轨道车辆分布式控制系统实时性能进行了分析及研究,得出基于通信网络的实时控制系统必须考虑网络的影响,特别是传输延迟的影响,同时根据应用实践提出了改善基于通信网络的车载分布式控制系统实时性的原理及方法,并进行了测试及验证.
