摘要: 通过NIM语言实现数据的实时采集、传输,并通过对显卡的编程操作实现绘图,同时用C语言对NIM语言进行重新编译,实现了承德中心台7套"十五"仪器原始数据的实时采集、传输及绘图。将12 h内的第1个数据作为坐标原点,进行实时坐标转换,绘制12 h内的原始数据实时曲线,进而实现对"十五"仪器原始数据的实时监控,方便值班人员随时查看。Abstract: In this study, through the NIM language recompiled by the C language, using the programming operation of the graphics card, a data real-time monitoring system is established and put into use on the 7 sets of instrument built during the China's 15th Five-Year Plan at Chengde central seismic station. The system take the first data of 12 hours as a coordinate origin making real-time coordinate conversion, and rendering 12 hours of raw data real-time curve, and then realizes data real-time monitoring for attendant to view at any time.
