Study And Design On Comprehensive Monitoring Platform Of Wi-Fi Complex Equipment On High-speed Railway

Study and Design on Comprehensive Monitoring Platform of Wi-Fi Complex Equipment on High-speed Railway is the urgent requirement of the high-speed rail Wi-Fi transportation management department and the focus of the railway intelligent operation and maintenance.Especially with the large-scale "Revival" directional train operation,the scale of the high-speed rail Wi-Fi service system is expanding,how to control and manage the operation status of the high-speed rail Wi-Fi system in real time,standardize the system operation management,and strengthen the platform operation and construction.Monitoring system emergencies to dynamically adjust operational strategies and save on emergency implementation costs has become an important issue facing the high-speed rail Wi-Fi operation and maintenance department.Based on the high-speed rail Wi-Fi operation service system architecture and application scenarios,this paper takes the network integrated monitoring ideas and methods as the starting point,and deeply analyzes the CPE(Customer Premise Equipment)WAN management protocol(TR069)and Zabbix open source framework,and integrates multi-dimensional monitoring indicators to build The integrated monitoring platform for high-speed rail Wi-Fi complex equipment realizes the functions of soft firmware management,status performance statistics,automatic configuration management,fault monitoring and diagnosis for the high-speed rail Wi-Fi operation service system terminal equipment.The main research work of the thesis is as follows:(1)In-depth analysis of the domestic and international status of research on integrated monitoring platform,according to the special application scenarios of high-speed rail Wi-Fi system,put forward the idea of building a comprehensive monitoring platform for high-speed rail Wi-Fi complex equipment.Based on the high-speed rail Wi-Fi system architecture and network structure deployment characteristics,the overall architecture and functional structure of the integrated monitoring platform for high-speed rail Wi-Fi complex equipment are proposed.(2)Through the in-depth study of key technologies such as cloud AC(wireless access controller),Zabbix open source monitoring framework and data storage based on TR069 standard protocol,according to the characteristics of TR069 south-to-north protocol deployment,design cloud AC and vehicle AC Level communication transmission,and Zabbix's excellent monitoring performance,Zabbix as the monitoring data transmission channel,design TCP/HTTP bridge to ensure the smooth communication between the monitoring agent and the monitoring server data,and solve the problem of monitoring data transmission across the network..The parameter monitoring,configuration management and statistical analysis of the high-speed rail Wi-Fi operation service system terminal CPE equipment are realized.(3)Based on the security design principles of the integrated monitoring platform,based on the 802.11b/g/n and 802.11ac protocols,a detection and protection scheme for unauthorized APs is proposed.Through the unique identification of the on-board AP of the high-speed rail Wi-Fi system,the embedded monitor chip is embedded to detect and block the illegal AP.At the same time,the ELK(Elasticsearch+Logstash+Kibana)log analysis technology is used to collect and transmit logs to the platform for storage,establish log index and provide retrieval service,and realize full link tracking of system application logs.(4)Focusing on the functional requirements of the integrated monitoring platform,in-depth analysis of the scalability of the monitoring platform,the integration plan for multi-system distributed data,the realization of equipment operating parameter information,the high sharing and visualization of train operation information and system operation information Show.
