摘要

分布式对象中间件在CBTC(基于通信的列车控制)接口仿真系统的应用是实现接口数据传输有效性、通用性、实时性的重要实现方式之一.针对CBTC仿真系统中各子系统间信息的交互和融合问题,通过研究当前分布对象中间件架构和运行机制,提出适合CBTC仿真系统信息交互的接口中间件,构建引入接口中间件工作模式的CBTC通信体系.详细阐述了该通信体系的体系结构及其接口的封装与设计,并将其应用到列车运行控制仿真系统中.此应用根本改变了轨道交通运行控制的运作模式,提高了系统的效率.%For effective and real-time interaction and integration of information between various sub-systems of CBTC (communications-based train control) system, the DOM (distributed object middleware) is introduced in the simulation system of CBTC interfaces, renamed as interface middleware, the current framework of DOM and its operational mechanism are studied. Besides, the packaging and design of the communication system are elaborated in detail, a communication system of CBTC based on interface middleware is set up, which will be applied in train operation control simulation to enhance the efficiency of the whole system.
