铁路平交道口的组件架构设计与分析

Railway Level-crossing Component Architecture Design and Analysis

铁路与道路平面交叉处的道口是事故的多发地点,如何处理好道口的交通和安全问题,已成为重要的研究内容。为了提高铁路道口系统的安全稳定性,必须对系统结构和运行状态进行设计、模拟和分析。文章采用组件技术对基于无线通讯的平面交叉道口进行了静态模型架构的设计和动态运行状态的分析,为铁路平交道口系统的安全分析和采取必要的安全措施奠定了基础。

Railway level crossings is a place of accidents of more occurring,it is particularly important to ensure vehicles and pedestrians passing through safely. In order to improve the dependability and safety of the system,it is necessary to design system structure,to analyze state of running systems. To this end,in this paper,static model architecture is designed based on component technology and dynamic analysis with state chart and sequence diagram,which is foundation and useful to Hazard analysis as well as taken some necessary safety measures.
