| The railway infrastructure consists of three major components:roadbed,rail,and bridge.Among the existing railway networks in China,there are more than 4,000 bridges,of which a considerable number are middle-aged and old ones.There are more than 7,000 tunnels with the total mileage nearby 4000 kilometers,and most of these tunnels are not in good conditions.Besides,China has a vast territory and the terrain is extremely complex for the railway lines.With the rapid development of the railway industry and its constant informatization,the requirements of the railway bureau for the monitoring and management of railways are also increasing.Through the railway safety monitoring data monitoring platform,the collected data is extracted,cleaned,and stored,and finally displayed and maintained in a centralized manner.This enables the monitoring center to monitor and analyze the monitoring spots in real time and comprehensively grasp the current operating status of each railway segment.The information provides data on the operational status of the railway and surrounding environment for the head office,railway bureau,and public works section personnel,and lays a solid foundation for the future establishment of a big data platform.The railway security and data monitoring platform adopts the B/S structure for its overall design,which improves the stability of the system and simplifies the development,maintenance and using process.The server adopts J2EE language(mainly SpringMVC and Hibernate)for server-related development in the background,with Weblogic as middleware.The physical structure of the system isolates the internal network from the external network through the firewall,which ensures the security of the system.The platform uses Oracle database which is more stable and efficient,and it meets the demand for a large number of data searches.In terms of data conversion,ETL tools were used to extract,convert and clean railway monitoring data.Divided from the function,the railway safety monitoring data monitoring platform mainly includes data cleaning module,data display module,and basic management module.The main function of the data cleaning module is that the monitoring data is extracted,converted,cleaned,and finally stored in a unified database;the main function of the data display module is to display the corresponding monitoring data according to the query conditions for use by the staff;the main functions of the basic management module are Measure the type of point,sensor type,monitoring log,etc.Through the above three modules,it is possible to monitor and maintain the operational status of the railways and improve the overall management level of the railway bureau on railway.Till now,with the development work finished,this platform has passed relevant tests and been submitted to the railway bureau for trial operation.The feedback shows that this platform satisfies all the requirements put forward by the General Railways Bureau.This platform can effectively monitor the data of the railways,greatly improved the timeliness and comprehensiveness of monitoring,and improved the safety monitoring capabilities of the general administration of railways and various railway branches. |
