The Railway Train Safety Early Warning System Based On Information Fusion Technology Research

As an important transportation system,railways play an important role in the development of transportation economy.With the continuous development of new technology,motor vehicles,high-speed rail and other advanced train gradually put into operation,to the train safety technology has put forward higher requirements.Therefore,it is of great significance to build a modern railway safety early warning system to improve the safety of railway transportation.The role of railway early warning system is to discover the hidden safety problems of railway train in time.It mainly has the following functions: accident description,accident interpretation,accident evaluation,accident prediction,analysis and decision.The construction of modern railway safety early-warning system can use the information fusion technology(data fusion technology),the information fusion technology can be applied to railway safety early warning system can effectively improve the railway safety early warning system accuracy and intelligence,to promote the railway early warning system The process of modernization has great significance.Information fusion technology is a new information processing method,which is based on the integration of information processing.Based on the traditional disciplines,information fusion technology is more important for the development of modern society.Meaning and broad prospects.Information fusion is the use of computer technology,information integration for processing and analysis.Including not only simple information processing,but also related to other areas,is to integrate all the relevant knowledge analysis.The basic principle of information fusion is to integrate the information collected by sensors scattered in various places,combine them with artificial observation data,observe them on space and time axis,extract the main information,mosaic the logically associated data,And then according to a certain algorithm and rules,the data optimization and integration analysis,resulting in analysis of results,to help make decisions while improving the level of intelligence.Based on the existing railway safety early-warning system and the development of the existing information fusion technology,this paper applies the information fusion to the railway safety early-warning system according to the characteristics of the two.Thefeasibility of constructing the railway early warning system based on information fusion is analyzed and analyzed from the aspects of the overall design framework of the system,the information sharing scheme of the system and the mathematical model of railway safety early warning system based on information fusion.This paper focuses on the research of the integrated technology of infrared axis based on information fusion,the technology of 5T guided repairing and repairing,the treading surface damage detection and forecasting technology of passenger train,and the data analysis of relevant examples,and expounds the safety of railway train based on information fusion technology from new angle.alarm system.
