基于多层网络体系的列车智能控制系统的研究

在对国内外列车智能系统发展的研究基础上，提出了基于多层网络体系的智能列车系统．该系统被划分为三个部分，现场级总线采用CAN总线，可提高底层系统的实时控制，控制级采用铁路专用网络，管理级采用以太网，在保证实时性的基础上减少了上层网络间的传输数据量．最后给出了系统在列车作业调度、通信实时性和列车定位等关键技术上的解决方法．

Research of Intelligence Control System of Train Based on Mult-layer Network System

Base on the research of the domestic and international railroad train intelligence system development, the paper puts forward the intelligence railroad train systems of the multi layer network system. The system is divided into three parts, the spot class adopts CAN bus that can increase the real time control of first floor system, the control class adopts the railroad private network, the manage class adopts ether net. Base on the real time, it reduces the data exchange between upper levels. At last, the paper gives a method of solution for system in train job schedule, real time of communication and location of train.
