摘　　要：针对地面塌陷所导致的高压输电塔塔架的形变过程测量与监测问题,研究了基于北斗载波相位差分定位的沉降位移测量方法。传统的现场观测测量存在步骤繁杂、无法实时监测的问题,提出了构建监测网监测卫星定位系统回传数据,通过位移转换算法实现输电塔架的实时监测。建立了塔杆变形模型,利用欧拉转角与欧拉转动矢量来描述监测面的形变。采用概率平均分布形变数据算法,分4次构建监测面取平均值,解决了欧拉转角描述不够准确的问题。通过实验与仿真分析可知,该方法能够实现对输电塔塔架的实时形变监测,相较于其他算法,该方法有效提高了数据处理速率以及形变监测的实时性。Aiming at the problem of measuring and monitoring the deformation process of the highvoltage transmission tower caused by ground collapse,a settlement displacement measurement method based on the BDS carrier phase realtime difference is studied.Traditional onsite observation and measurement has complicated steps and cannot be monitored in real time.It is proposed to construct a monitoring network to monitor carrier positioning system to return data,and realize real time monitoring of transmission towers through displacement conversion algorithms.The tower pole deformation model is established,and the Euler rotation angle and Euler rotation vector are used to describe the deformation of the monitoring surface.Using the probability average distribution deformation data algorithm,the monitoring surface is constructed in four times to take the average value,which solves the problem of insufficient accuracy of the Euler angle description.Through experiments and simulation analysis,this method can realize real time deformation monitoring of transmission towers.Compared with other algorithms,this method effectively improves the data processing rate and realtime deformation monitoring.
