基于NI-DAQ的高采样实时数据绘制方法与实现

飞行试验实时监控中,对高采样数据通常采用曲线绘制进行分析与故障判断,这对数据绘制的实时性、精确性以及曲线长度等都提出了较高的要求。本文对基于NI-DAQ的曲线绘制方法进行了研究和软件设计,实现了客户端的高采样数据实时绘制与打印输出。结果证明,采用该方法绘制的参数曲线可以满足实时监控要求。

Curve Plotting Method of High Sampling Real-time Data Based on NI-DAQ

In real-time monitoring of flight test, the high sampling data is generally analyzed and judged by means of curve plotting, which must have the characteristic of real-time, high precision and enough length. In this paper, the curve plotting method of high sampling data based on NI-DAQ is researched and implemented. The results show that, the curves plotted by this method meet the requirement in real-time monitoring.
