铁路客运专线运营调度系统体系结构

客运专线运营调度系统由运输计划、列车调度、动车调度、供电调度、旅客服务调度、综合维修调度及防灾安全监控7个子系统组成。基于逻辑层次化、组件化、面向服务和事件驱动等设计理念,设计系统的体系结构由运行环境、技术平台、业务处理平台、安全保障体系和运营维护体系5层构成。运行环境提供系统正常运行的软件和硬件环境。技术平台包括管理运行平台、控制运行平台、消息中间件和对外信息接口。业务处理平台包括应用处理、系统管理和决策支持模块,直接提供用户人机界面。安全保障体系从8个方面综合考虑系统安全保障策略。运营维护体系包括日常运行维护服务、运营技术支持及运行维护规章制度。该系统的软件架构以B/S与C/S模式相结合,但以B/S模式为主。基于该体系结构,实现了包含运营调度系统核心处理功能在内的仿真实验系统的开发。

System Architecture of Railway Passenger Dedicated Line Operation and Dispatching System

The operation and dispatching system of railway passenger dedicated line consists of seven subsystems including traffic planning,train dispatching,EMU dispatching,power supply dispatching,passenger service dispatching,comprehensive maintenance dispatching and disaster prevention and safety monitoring.With the design vision based on logic hierarchilization,groupwarelization,service oriented and event driven,the architecture of the design system is built in five layers including operating environment,technical platform,operation processing platform,safety guarantee system and operating maintenance system.Operating environment provides software and hardware environment running in a right condition.Technical platform consists of management operating platform,control operating platform,message middleware and information interface to external.Operation processing platform consists of application processing,system management and decision support,provides customer with man machine interface directly.Safety guarantee system takes into account safety guarantee policy in eight aspects.Operating maintenance system consists of daily operating maintenance service,operating technical support and operating maintenance regulations and rules.The system architecture is a combination of B/S and C/S,but mainly B/S model.Based on this system architecture,we developed a simulation system comprising operation and dispatching system core processing functions.
