| 摘 要： | 基于UDP（用户数据报协议）组播数据传输方式,通过对接收到数据包中相关PDXP（包数据交换协议）字段的实时解析和挖掘分析,采用BackgroundWorker（后台工作者线程）模型简化多线程交互方式,以分级缓存为基础优化数据存储结构,通过直接调用GDI（图形设备接口）＋绘图接口设计开发高效的UI（用户接口）显示控件,并且利用Linq（语言级集成查询）数据访问技术,以可视化的形式对PDXP数据包的丢包和乱序等问题进行实时判读和基于源码的分析,提供了一种对中心之间交互的数据进行实时连续性监视分析的简捷、直观和有效的途径。

| Abstract: | Based on UDP multicast transportation method,the data monitoring software parses and analyzes PDXP（Packet Data Exchange Protocol） data in real-time.Using BackgroundWorker model and layered buffering mechanism,it simplifies multi-thread interaction and optimizes data structure.To further improve software performance,efficient user defined UI controls are developed by calling directly GDI＋ interface.Linq data query technology is used to identify loss of PDXP data packets and disorders in visualized form and to provide bytes-based analysis.As a result,the software provides an easy,instant and effective way to continuously monitor data transmission between centers. |
