无人机的舵机数据采集方法研究

针对无人机半物理仿真中多路舵机传感器的电压采集，以VC＋＋可视化语言为开发工具，设计了一套基于PCL_812PG采集卡的数据采集软件。软件采用了WM_TIMER和多媒体定时器两种定时采集方式，实现了采集数据的实时显示、存储等功能；最后给出了两种方式下的采集数据对比。结果表明，在采样频率要求较高的情况下，WM_TIMER“丢秒”较严重，而多媒体定时器非常准确，精度达到ms级，很好地完成了数据采集的目的。

Research of data sampling method for rudders of UAV

In order to implement the signal sampling of multi-sensors of rudders during the UAV semi-physical simulation, sampling software was developed based on PCL_812PG by using VC++.Two types of timer,WM_TIMER and multimedia timer, were employed in the software,and functions such as data real-time display and storage were realized.The lab outcomes show that,under high sampling frequency, WM_TIMER leads to severe second loss, while multimedia timer achieves high level of precision, which accomplished the goal of d...
