城市轨道交通安全智能融合监控体系的构建

从轨道交通所具有的开放的复杂巨系统特性出发,探讨实现轨道交通安全智能监控目标的一条途径———智能融合理论和方法体系。采用系统工程全方位思维模式,将知识工程、信息智能处理等理论和方法,与传统的数学、信号处理方法相互渗透和融合,来完成轨道交通安全监控中的各项工作。将智能融合监控分为数据级融合、分析级融合、诊断级融合和评价级融合等4级体系结构,叙述了各级融合的基本原理和典型实现方法。该融合监控体系能够对轨道交通系统安全状况及安全级别做出综合分析和评价,从而实现全过程的轨道交通系统安全分析和评价。

Intelligent Fusion of Theories and Monitoring Methods for Urban Trail Transit Safety

At present,incidents occur frequently due to the construction peak of urban rail transit in China.An opened complex giant system that implements the fusion of theories and methods is presented in this paper,its structure is composed of four fusion levels: data,analysis,diagnosis and evaluation.Positive-thinking pattern is a systemic mode of system engineering,which integrates the theories of knowledge engineering and information processing with traditional mathematics and mechanics.The basic principles and representative methods on intelligent fusion are introduced,which could provide a comprehensive analysis and assessment on the present condition of urban trail transit safety,classify the hazard level of urban trail transit system and realize the whole process evaluation of rail transit safety.
