[Abstract]:With the rapid development of railway in China, the content of wireless data transmission required by railway informatization is more and more. GSM-R is a special system specially designed to meet the demand of railway for mobile communication. The GPRS network based on GSM-R mainly provides railway operation and dispatch information, railway facility maintenance and management information, passenger service information and other non-secure wireless data transmission services. Because the GPRS critical network element equipment in GSM-R network lacks the real time and effective monitoring means in actual service running state, it is unable to effectively monitor whether the GPRS key network element equipment service is running normally or not. It is difficult to find fault or problem of equipment in the first time, and there is a great hidden trouble in safety. Once the business is interrupted, the failure to find and deal with it in time will directly affect the safety of driving. It is necessary to build a comprehensive GPRS network active monitoring system to ensure the safety of railway operation. This paper mainly introduces the background and significance of GPRS network active monitoring system, related technology, system requirement analysis, architecture design, design and implementation of main functional modules and system testing. The system is based on .NET platform, uses C / S architecture and distributed architecture. The system mainly includes real-time test data collection, real-time test data analysis, system internal monitoring, real-time visualization of data display, user management, equipment management. Exception and alarm information processing module. The whole system and the design and implementation of each module will be described in this paper. I am mainly responsible for real-time test data acquisition, real-time test data analysis, real-time data visualization module, participate in the system distributed architecture and system communication architecture design and implementation. The realization of the system can improve the current monitoring means of the railway GPRS network, monitor whether the key network element equipment of the GPRS network is online or not, and whether it can provide the normal service in real time. We can find out whether the important GPRS business function equipment is running normally or not, and give the warning prompt when the equipment is in trouble, so that the maintainers can deal with it quickly and compress the fault delay as much as possible. At the same time, the system will provide a streamlined, low-threshold monitoring client, and encapsulate railway related business and standards in the service side, so that users do not need to know the relevant business and railway data standards. The key equipment in railway GPRS network can be obtained intuitively.
