摘　　要：eXtremeDB内存式实时数据库是为实时系统及嵌入式系统而特别设计的数据库。为满足多用户实时监控火箭发射的状态变化,本文设计了基于eXtremeDB实时数据库和主动式B/S模式的遥测数据实时监控系统。它与一般的监控系统不同,实现了多用户通过Web对实时数据进行监控和查询的功能,其客户端采用ActiveX和WinInet技术实现对服务器数据的实时显示,并增加数字签名验证功能以保证其安全性,具有响应时间短、查询速度快、丢包率低、界面友好等特点。The eXtreme DB In-memory Database is specially designed for real-time system and embedded system, The telemetry data real-time monitor system is just based on the eXtremeDB database and it apply pro-active B/S mode technology to satisfy multi-user monitor the rocket status. This is different from other monitor systems in that it satisfies multi-user different monitor and query through the web. The client uses ActiveX and WinInet technology to display real-time data. Its digital signature certification is imple- mented to ensure security. Moreover, it has characteristics such as short response time, quick query speed, low rate of data package dropout , and friendly UI.
