摘要
提出了一种以多媒体工业控制机进行信息实时采集及处理的方法,并以三相交流异步电动机变频调速拖动系统为例,利用多媒体工业控制机速度快、存储量大、易于开发等优点,对电机的相电压、线电流、转速等信号进行实时采集、存储并对其进行信息处理,同时利用多媒体功能,可以随时对现场声音信号进行记录和对视频图象进行捕获,并与采集的电压、电流、转速等信号数据形成一个综合数据文件,然后由信息处理软件处理.经过实测比较表明,该信息采集系统在精度上优于HP54501A型存储示波器。
A method of sampling and processing of real-time information using multimedia industrial computer is presented. Such information as analogous signal, digital signal, sound signal and video image are sampled in real-time and stored as a comprehensive data file, so it can be processed in later. After doing experiments, the results prove that this system has excellent characteristics of real-time and accuracy.
