| 摘 要： | 介绍了地震数据采集器监控软件的设计思路，特别是在实时波形显示上，采用“环形”的显示缓存和“滑动显示窗口”技术，大数据量时也能以左移的方式连续显示实时曲线的动态变化；实时波形的纵坐标范围也是动态变化的，在任何时刻都恰好能在显示区域内完整显示。文章还介绍了如何在显示中消除明显的屏幕闪烁现象，以及对数据从传输到存储、显示的分层设计思想和多线程技术的应用。

| Abstract: | In the paper, it is introduced that the design concept of the monitor software of earthquake acquisition system, especially using the technology of ＂circle display memory＂ and ＂slide display window＂ on the display method of the real time waveform. With these techniques, the real time waveform can be continuously displayed in left-shift mode, even though the data are mass. The real-time waveform can exactly coincide with the display area while the range of the y-axis scale is varying. In the paper, it is also introduced how to avoid the phenomena of the screen flash and the application of the technology of the multilayer design concept and the multithread. |
