数据采集和控制系统多种多样，但其基本工作过程相似：汇集被测控对象各种被测模拟量，把它们转换为数字信号，经过加工处理后，再转换成相应的模拟量，实现所需的控制。上述过程由数据采集控制器统一管理和调度。-Data acquisition and control systems are diverse, but similar to the basic work process: collection of various objects being tested analog measurement and control, convert them to digital signals, after processing, the converted to the corresponding analog, to achieve the required of control. The process from data acquisition controller unified management and scheduling.
