摘　　要：大型汽轮发电机组运行中的振动对设备的危害极大,可导致停机甚至断轴事件的发生,离线定期监测不能保证监测的持续性,在线监测分析以预防事故发生为主,在设备出现问题之初就将其解决。提出并实现了振动在线实时监测分析系统,基于Applet+JavaEE(MVC)+MySQL技术,重点研究了网页中的多窗口图形显示、数据交互与消息机制。整合了电厂网络和Internet资源,终端用户只需要一个网页浏览器就可以进行设备状态的监测,并能做到远程实时监测。系统实现了多个图谱,具有与历史数据比较分析的能力,并提供数据上报功能,以满足电厂和集团等不同级别用户的需求。Vibration is very harmful to large turbine-generator sets. It may cause the turbine to shut down, or even the shaft to break. Offline periodic monitoring cannot realize continuous monitoring. By contrast online monitoring and analyzing mainly focus on accident prevention and can discover fauhs early. An online real-time vibration monitoring and analyzing system based on Applet＋JavaEE （MVC）＋ MySQL technology is developed, capable of displaying muhi-window graphics on one webpage, and exchanging and messaging data as well. By integrating the power plant＇ s network with the Internet resources, end users can perform state monitoring and remote real-time monitoring in one Web browser. The system has more than one map and has the functions of making comparisons with historical data and data uploading, to meet the needs of users at different levels, such as power plants and groups.
