地铁应急演练与辅助决策系统架构设计

针对地铁应急演练、信号故障监控、辅助故障处理等应用具有系统实时性要求较高、
数据传输量较大等特点，利用Ajax模式和MVC架构相结合的方法设计并实现了一种采用
Ajax + Struts + Hibernate框架的地铁应急演练与辅助决策系统。该系统结合了Ajax技术快速异步响应和MVC架构成熟稳定等的特点。实验表明：采用该架构能有效地降低客户端与服务器的通讯量，显著提高系统性能。

Abstract: Metro emergency drilling, signal fault monitoring and decision-making support system has a higher real-time requirements and a greater volume of data transmission contrast with other system. This paper presents a method to solve all these problems based on the integration of Ajax and MVC model. The System combines the technology of Ajax, Struts and Hibernate. The experiment indicated that in the method proposed, communication between browser and server is reduced and the delay of pages refresh has become much lower than before. This framework improves system performance significantly.
