轨道交通监控系统集中式和分布式结构研究

On the Centralization and Distribution of Monitoring and Control System for Rail Transit

分析了轨道交通监控系统集中式结构和分布式结构的软件模型和硬件配置,从可靠性和成本、实用性和可扩展性、可维护性和单一的应用等方面,对两种结构进行比较。结合轨道交通实际运营需求,提出了不同运营管理模式下的系统构成方案。同时,根据"单一的应用"的概念,对系统构成方案进行了优化,在保证系统可靠性的前提下,提高系统可维护性,达到降本增效的目的。

After analyzing the software model and system configuration, then combined with the actual demand for rail transit operation, a proposal for constituting a system plan is forward based on different management modes. According to the conception of ＂single application＂, the system structure is optimized to ensure a higher reliability, This solution is expected to improve the maintenance of the system, achieve the goal of reducing cost and enhancing efficiency.
