High-precision foundation pit displacement data processing method
The invention provides a high-precision foundation pit displacement data processing method, which comprises the following steps that: a measuring station is arranged at the edge of a foundation pit, and a base station is arranged in an open area which is far away from the foundation pit and is stable in rock soil; the measuring station and the reference station respectively receive satellite positioning signals of satellites, analyze the satellite positioning signals and transmit the analyzed satellite positioning signals to the cloud server; the cloud server resolves a differential positioning result between the measuring station and the reference station, and divides the differential positioning result in a preset monitoring time interval into n sub-periods according to a period T to obtain a differential positioning set K containing the differential positioning results of the n sub-periods; gaussian smoothing filtering processing is carried out on the set K to remove abnormal points with deviation, and a differential positioning set L is obtained; performing signal keeping filtering processing on the set L to remove noise to obtain a differential positioning set M; performing Kalman filtering processing on the set M to obtain a foundation pit displacement detection result N; according to the method, more effective real-time following is carried out on abrupt change signals, noise is effectively eliminated, and the result is more accurate.
本发明提供一种高精度基坑位移数据处理方法，包括：将测量站布设在基坑的坑边，基准站设在远离基坑、地势空旷且岩土稳定的区域；测量站和基准站分别接收卫星的卫星定位信号，并解析后传输给云端服务器；云端服务器解算测量站与基准站之间的差分定位结果，将预设监测时间区间内的差分定位结果按照周期T分割成n个子时段，得到含n个子时段差分定位结果的差分定位集合K；对集合K进行高斯平滑滤波处理，以去除存在偏差的异常点，得到差分定位集合L；对集合L进行信号保持滤波处理以去除噪声，得到差分定位集合M；对集合M进行卡尔曼滤波处理，得到基坑位移检测结果N；本发明针对突变信号更有效的实时跟随，有效消除噪声，结果更准确。
