摘要

为了减轻非线性因素和环境温度的变化对倾角仪测量的影响

在充分研究倾角仪测量特性的基础上

采用多项式拟合方法研究了倾角仪非线性误差和温度漂移误差的软件补偿技术。建立了测量误差与非线性输出的多项式模型

拟合求出了多项式模型的各个系数与环境温度的关系函数

得到了倾角仪在一定倾角范围和温度范围内的测量误差的计算公式。实验证明了方法的可行性和有效性。

Abstract

To reduce the impacts of nonlinearity and variation of environment temperature on the measurement of the inclinator

a software compensation technology for the inclinator’s nonlinear error and temperature drift error is studied using the method of polynomial fitting

on the basis of fully research on the measurement characteristic.The polynomial model between the measurement error and the nonlinear output is built.The relational function between each coefficient of the polynomial model and the environmental temperature is obtained by fitting.A calculation formula of the inclinator’s measurement error in a range of inclination and temperature is acquired.The experiment demonstrates the feasibility and validity of the proposed method.
