Abstract: In order to grasp the real time running state of railway EMU WiFi operation service system, improvethe system operation and maintenance efficiency, shorten the response time after sale, reduce the consumption ofemergency resources, make the operation management and service intelligent, this paper proposed a Zabbix basedcomprehensive monitoring system. On the basis of Zabbix open source framework and data visualization, combinedwith the deployment environment and application scenario of railway EMU WiFi operation service system, thearticle studied the key technologies of Zabbix monitoring system around the actual requirements of system operation,maintenance and management. Using the excellent performance and expansibility of Zabbix, the data of on-boardWiFi equipment system parameters, train running information, platform operation and so on were highly centralizedand visualized. At the same time, the real-time, efficient push mechanism was established by using push media to buildmulti-level, three-dimensional integrated monitoring and management platform, implement a high degree sharingof resources and data of the railway EMU WiFi operation service system. Making full use of the existing technicalconditions can improve the level of efficient, unified and intelligent for the operation and maintenance of railway EMUWiFi operation service system.
