摘　　要：CBTC(基于通信的列车控制)轨旁ATP(列车自动防护)在处理列车相关信息时,面临着因信息来源多样、信息延时多变、报文异步等问题导致列车逻辑错位、列车状态转变的情况,不利于CBTC的互联互通。为此,提出了一种用于描述互联互通CBTC系统列车序列的方法,通过分析列车信息的数据来源特征,设计了一个抽象的中间描述层(多源信息中间件),向轨旁ATP系统的主要功能模块隐藏列车信息的来源细节。该方法降低了CBTC接口变化对核心功能模块的影响,可方便地适配不同的信号系统制式,大大增强了轨旁ATP核心功能的泛化能力。When trackside ATP(automatic train protection)CBTC(communication-based train control)system deals with train related information,it is faced with situations of train interlocking displacement and status switch brought by problems such as diversity of information data source,delay and uncertainty of messages,asynchronization of information sources.These problems go against the interoperation of CBTC systems.Therefore,a method for describing interoperable CBTC system train sequence is proposed.By analyzing features of train information data source,an abstract sub-layer(multi-source message-oriented middleware)is designed,hiding details of train information sources to the kernel functionality modules of trackside ATP system.This method reduces the influence of CBTC interface variation on kernel ATP modules,allowing convenient adaptation to different signaling system formats,and greatly improving the generalization ability of the kernel trackside ATP module.
