Embodiment Construction
[0017] The present invention will be further described below in conjunction with accompanying drawing and embodiment: figure 1 It is a schematic diagram of the principle of the present invention.
[0018] like figure 1 As shown, the data correction method for improving measurement accuracy in this embodiment includes
[0019] Collect continuous indirect measurement data to be corrected, and establish segmental nonlinear correction model I and segmental nonlinear correction model II,
[0020] Set the hysteresis interval q-p, where the critical threshold q<p, when the measured continuous indirect data value is less than the critical threshold p, use the segmented nonlinear correction model I for correction, when the measured continuous indirect data value increases to greater than the critical threshold When p, the piecewise nonlinear correction model II is used for correction.
[0021] When the measured continuous indirect data value increases to be greater than the critical...
