基于Web的高速动车组跟踪监测数据可视化研究

Study of Tracking and Monitoring Data Visualization for High-Speed EMU based on Web

针对高速动车组结构监测数据种类多、实时和历史数据量大的特点,基于Web技术开发了高速动车组跟踪监测数据可视化系统.采用三层可视化层次结构,提出了特征值取值、基于时间戳的数据同步等方法,并使用Web地图和AJAX读取技术等,实现对动车组的运行位置、不同车辆各类监测数据的可视化处理和显示.最后,应用此数据可视化方法,通过对动应力等数据的处理和动态显示,做到对多项监测数据的整合,满足了动车组监测数据的可视化需求.

According to the characteristics of various structure monitoring data and large amount of real-time and historical data of high-speed EMU,a visualization system for tracking and monitoring data of high-speed EMU is developed based on Web technology. A three layer visualization hierarchy,an eigenvalue selection method and a timestamp data synchronization method are proposed. The visualization system is realized to display the position of EMU and visualize the monitoring data of different vehicles through Web map and AJAX technology. Finally,an application example in which the data visualization method was applied to long-term tracking and monitoring is given. Through processing and dynamic display of the dynamic stress and other data,the integration of the monitoring data is achieved,and EMU monitoring data visualization demands is satisfied.
