The invention relates to a sensing measuring instrument online soft calibration method and a device achieving the same. The method comprises the steps of collecting original data, obtaining an original sample total average value and an original sample standard deviation average value, obtaining an average value control graph and a standard deviation control graph, collecting detection data, obtaining a detection sample average value and a detection sample standard deviation, performing detection data dot drawing, performing result determination and outputting. According to the method, a measuring instrument is monitored by means of the control graphs, a control graph generation stage and a control graph detection stage are included, the method can precisely detect the accuracy of the measuring instrument during working, and therefore continuous and stable operation of a production line is ensured. The device is simple in structure, convenient to realize and easy to operate. 本发明涉及种本发明的传感计量器具在线软校准方法和实现该方法的装置，方法
