利用低精度测量元件进行高精度采集的方法探讨

Method of High Precision Collection by Measuring Element of Low Precision

提出了一种能校正系差的检测控制系统,当被测物理量能被定义为"低速变化物理量"时,利用误差理论对被测信号数据进行数据处理,可以达到用低精度采集系统进行高精度采集的目的。

The authors proposed a system which can be used to revise error or control. When the measured physical quantity can be defined as the low speed change physical quantity, using the error analysis theory to deal with the measured signal, the high precision collection by measuring element of low precision could be gained.
