摘要
为适应城市轨道交通的发展,列车自动监控(ATS)软件需要具有在同一线路上设置多种运营线的能力,需要适应不同厂商和规格的硬件,需要适应多种拓扑结构的线路形式和线路网络化管理要求,需要集成实时客流信息。为此,结合客流信息、线路模型等问题,在模块设计中采用以数据为核心的分层方法,在元数据设计中增强系统模型的描述能力,从数据结构到监控画面深度集成实时客流数据,在数据操作方法中应用主动、实时和关系数据库技术。通过这些举措使ATS达到了设计要求。
To meet the requirements of urban rail transit, the automatic train supervision （ATS） software should be able to set up multiple operating lines on the same rail line based on the passenger volume. It should also adapt to the rail transit network management and the diversified line topological structure, and to the hardware requirements of different manufacturers, so as to integrate the passenger volume in real-time. In AST, a layered design method oriented to the data is adopted, which can enhance model description ability from metadata, apply real-time, active and relational database technology, highlight real-time passenger flow on the monitoring screen, making the ATS meet these requirements.
