摘要:

光纤陀螺全站仪可以通过感应地球自转测定地理北方向。但在实际应用中发现温度变化是影响光纤陀螺寻北精度与稳定性的重要因素。在对光纤陀螺输出数据与温度进行相关性分析的基础上,设计了一种应用于光纤陀螺寻北的BP神经网络建模温度补偿方法。设计了温度补偿试验对模型的可行性和有效性进行验证,相较于常用多项式模型,该模型补偿后陀螺输出的零偏稳定性有一定程度的提高;并在某煤矿寻北定向测量中进行了应用,与导线测量结果对比分析,取得了一定的定向效果,可为类似工作提供参考。

Abstract:

Fiber optic gyroscope total station can determine the geographic north direction by sensing earth rotation. However, it is found that the temperature change is an important factor affecting the accuracy and stability of the fiber optic gyroscope. Based on the correlation analysis between the output data of fiber optic gyroscope and the temperature, a BP neural network modeling temperature compensation method for fiber optic gyroscope is designed. The temperature compensation experiment is designed to verify the feasibility and validity of the model. Compared with the common polynomial model, the zero-bias stability of the compensated gyro output is improved to some extent. The method has been applied to a coal mine's north-seeking orientation measurement and obtained certain orientation effect by comparing with the result of traverse measurement.

Key words: fiber optic gyroscope, temperature compensation, BP neural network, Allan variance
