| 摘 要： | 利用后台多线程与事件触发技术,实现对地震前兆仪器实时数据的动态展示;通过对实时数据进行长短窗比值与4倍均方差、时均值、日均值等计算,实现实时数据的异常报警功能,并将该功能模块封装成独立控件供用户使用。该控件可实现对全国所有支持实时采集的前兆仪器进行实时数据采集与动态曲线绘制,可实现对各仪器测项实时曲线的浏览观测,具有自动连接、断网重连、网络状态显示、数据异常报警等功能,同时起到仪器监控的目的。

| Abstract: | In the text, how to dynamically display the real-time data gathered from earthquake pre- cursor instruments based on background multi-thread and event-trigged technology is presen- ted. And how to realize the data abnormity alarm by the ratio of long and short windows, 4 times mean square deviation, daily mean and time-averaged is also described. All functions were packaged into a control to use for people. The control can gather the real-time data from the earthquake precursor instruments all over the country and display dynamically different items data curves. The control has many functions, for example, automatic connection, recalling the connection after net disconnected, net state display, abnormity data alarm, monitoring instruments and so on. |
