面向微服务架构的列车调度管理系统设计

Design of Train Dispatching Management System Oriented to Microservice Architecture

为更好地适应现代有轨电车统一集中平台的列车调度管理系统建设,降低运维成本,提高运维效率,采用面向微服务架构的软件组建及开发方式,应用高性能通信协议、冗余消息队列和嵌入式集成框架等技术,设计了具有系统进路模式、轨旁监控、车载监控和时刻表/运行图等功能的模块。同时搭配基于“点-线”模型的线路拓扑数据库,打造出能与其他弱电系统更灵活集成的综合自动化平台。已在北京冬奥会崇礼有轨电车项目得到良好应用,后续将扩展面向全生命周期的应用。

In order to better adapt to the construction of the train dispatching management system of the unified and centralized platform for modern trams,reduce the operation and maintenance cost,and improve the operation and maintenance efficiency,the software construction and development method using the microservice-oriented architecture was designed,and the technologies such as high-performance communication protocol,redundant message queue and embedded integration framework were applied to make it have functional modules such as system route mode,trackside monitoring,on-board monitoring,timetable/train diagram,combined with the line topology database based on the"point-line"model,creating a comprehensive automation platform that can be more flexibly integrated with other weak current systems.This technology has been well used in the Chongli tram project of Beijing Winter Olympics,and will be extended to full-life-cycle applications in the future.
