摘　　要：传统的光纤测距方法采用特征阻抗检测技术,受到回波信号的峰脊陡变效应的影响,测距精度不准确。提出一种引入数据冲突监测和碰撞思维的光纤优化测距算法。提取测距信息的数据冲突信息特征,对高稳定性低压差线性测距测量系统发出的主频进行分析,考虑不同坐标中心的偏差与测量误差,通过数据整合获得横波坐标位置定位。当入射两固体介质面或粘滞弹性界面时,分析反射和折射的横波碰撞过程,设计自适应滤波器,求得峰脊陡变信息分量回波相对于发射信号的时延,通过传感器测量位移和速度参数,实现光纤测距。实验和仿真结果表明,采用该算法能有效抑制峰脊陡变效应的影响,提高测距精度,在传感器设计与应用中具有较高价值。The traditional optical ranging method uses the characteristic impedance detection technology, and the ranging accuracy is not accurate under the influence of peak ridge abrupt change effect of echo signal. An optical fiber optimization ranging algorithm based on data collision detection and collision concept is put forward. Data conflict ranging information feature is extracted, the main frequency of the linear range measurement system with high stability and low dropout is analyzed, considering center deviation and error of measurement of different coordinates, shear wave coordinate position location is obtained through data integration. When incident to the two solid medium surface or viscoelastic interfaces, reflection and refraction of the transverse wave collision process is analyzed, an adaptive filter is designed, and time delay of the peak ridge abrupt change information component echo relative to the transmitting is obtained. The sensor can realize optical fiber distance measurement by measuring the displacement and speed parameters. The experimental and simulation results show that the proposed algorithm can effectively restrain the effect of the abrupt change of peak ridge, improve the ranging accuracy, and has high value in the sensor design and application.
