基于陀螺儀與傾角儀組合的TBM姿態(tài)角測量研究
[Abstract]:Because the tunnel construction environment of TBM is mostly mountain rock structure, it is easy to be subjected to severe vibration shock in the process of tunneling, which will lead to the measurement misalignment or even failure of the inclination sensor in the attitude angle measurement system. The gyroscope sensor has the characteristics of strong anti-vibration and can be used as the sensor for measuring the attitude angle of TBM in strong vibration environment. In order to improve the accuracy and stability of TBM attitude angle measurement system in vibration environment, a TBM attitude angle measurement method based on biaxial tiltmeter and triaxial gyroscope is presented in this paper. The measurement performance of tiltmeter and gyroscope at different vibration frequencies is analyzed, and the resonant frequency section where the measuring failure of tiltmeter is found. When the tiltmeter is resonant and the measurement fails, the measurement performance of the gyroscope is not greatly affected. The results of frequency sweep vibration test show that the gyroscope can be used to measure the attitude angle of TBM when the tiltmeter fails. However, it is necessary to estimate and compensate the random drift error of the gyroscope in order to ensure the long-term stability measurement of the gyroscope in the vibration environment. The main random drift error term of MEMS triaxial gyroscope is analyzed by Allan variance method, and the random drift error model of the gyroscope is established according to the analysis results. The accuracy of the error model is verified by the simulation experiment. Based on the error model of gyroscope, the multi-sensor fusion estimation model of extended Kalman filtering algorithm is established. Using the high precision angle information output when the tiltmeter does not fail, the zero deviation of the gyroscope output angular velocity is estimated by extended Kalman filter in real time. When the tiltmeter fails in the strong vibration environment, it can be used to estimate the zero deviation of the gyroscope output angular velocity in real time. The TBM attitude angle can be obtained by integrating the angular velocity of gyro after zero offset compensation. Finally, through the simulation experiment and the test of the experimental platform, the proposed fusion system attitude measurement algorithm can effectively measure the attitude angle of TBM in strong vibration environment, and has high reliability. It can meet the precision requirement of attitude angle measurement in the construction of TBM tunnel, and has the practical application value.
