摘要
对地铁综合监控自动化系统中一些关键技术的解决方案进行了探讨。在系统软件平台的设计中,采用了基于中间件组件技术的软件架构和实时分布式数据库技术;在通信控制站(输入/输出)设计中,强调内核和应用的相对独立性,并在此基础上实现接口编程模式的统一;数据订阅采用动态订阅-发布机制,提高骨干网数据传输的实时性和可靠性。基于以上关键技术的系统平台在北京地铁13号线得到了现场验证。
This paper introduces solutions to the critical technologies of the integrated supervisory and control system （ISIS） in metro. In the software platform design, the distributed processing and real-time database based on middleware are adopted. In the design of communication station, the retain of the relative independence and stability of the kernel is emphasized, so the uniform interface program mode can be realized. By using dynamic subscribing and issuing mechanism, the real-time performance and reliability of data transmit on main backbone network can be greatly enhanced. All these key technologies are proved successfully in Beijing Metro Line 13.
