摘要:
为克服传统的变形监测手段与使用单一卫星定位技术在监测精度方向的不足,融合GNSS与加速计变形监测技术,设计出具备高精度、智能化的地涵变形监测系统;通过克服GNSS与加速度计空间基准的统一以及GNSS与加速度计时间同步问题,提出多星座融合的GNSS模糊度解算处理算法、面向GNSS与加速度计融合的数据解算算法,提高了地涵变形监测的精准度。灌河地涵变形监测实际应用表明:该地涵变形监测系统在授时稳定性、时间同步性、定位精度等均满足设计要求,能够准确监测地涵的变形信息,具有应用潜力。
Abstract:
To overcome the shortcomings of traditional deformation monitoring methods and the use of single satellite positioning technology in the direction of monitoring accuracy, a high-precision and intelligent ground culvert deformation monitoring system is designed by integrating GNSS and accelerometer deformation monitoring technology. By overcoming the unification of GNSS and accelerometer spatial benchmarks and the problem of time synchronization between GNSS and accelerometers, a multi constellation fusion GNSS ambiguity resolution algorithm and a data resolution algorithm for GNSS and accelerometer fusion are proposed to improve the accuracy of ground cover deformation monitoring. In the practical application of deformation monitoring of Guanhe culvert, it has been shown that the designed ground culvert deformation monitoring system, which meets the design requirements in terms of timing stability, time synchronization, and positioning accuracy. It can accurately monitor the deformation information of the culvert and has application potential.
