调平的测量误差分析与倾角传感器精度的选择

为减小调平误差,正确选择合适的传感器及其精度,以平台调平的倾角测量为研究对象,通过分析和计算推导出平台水平倾斜度与测量的方向倾角之间的数学关系式,并运用数学理论及误差合成原理重点对测量误差进行分析处理;最后在分析倾角传感器具体误差内容的基础上,以平台水平度允差作为误差参考标准,得到了在实际应用中平台调平的判断准则及传感器精度参数选择的理论依据,为后续的实验验证奠定了基础.

Analysis of Measurement Errors on Leveling and the Selection of Tilt Sensor Accuracy

In order to reduce the error of leveling and choose sensor with appropriate accuracy,tilt angle measure-ment is taken as research object in this paper. Firstly,the relation formula between the angle of platform inclination and directional measurement angle is derived through analysis and calculation,then measurement error is emphasis-ly analyzed and processed with mathematical and error combination theory. Finally,based on the analysis of con-crete errors including system errors and random errors,the judgment standard of platform leveling and the parame-ter selection of sensor are put forward in practical application according to the permissible error of levelness ,and lay the foundation for continued testing.
