摘要:

2021年南水北调中线工程天津干线建立了包含102个国产北斗监测站点的沉降监测系统,每天新增约6.4 GB的原始观测数据和2 125个沉降监测结果。工程距离跨度大,人工巡检效率低,难以快速、及时地对监测站点的健康状况进行诊断。为解决此问题,提出了一种面向海量北斗变形监测数据的站点健康诊断自动化技术。利用多路径误差是否长期大于阈值、沉降序列是否发生突变,实现对北斗监测站点周围观测环境和稳定性的及时诊断,以较低的人力成本实现对北斗监测站点周围植被生长变化和土质沉陷异常变化的快速分析和诊断。

Abstract:

The Tianjin mainline of the South-to-North Water Diversion Project established a settlement monitoring system in 2021, which includes 102 domestically produced BDS (BeiDou Satellite) monitoring stations. Approximately 6.4 GB of raw observation data and 2 125 settlement monitoring results are added daily. Due to the large span of the project and the consequent low efficiency of manual inspections, it is difficult to quickly and promptly diagnose the health status of monitoring stations. To address this issue, we propose an automated health diagnosis technology for stations with massive BDS deformation monitoring data. By assessing whether the multi-path error exceeds a threshold for a long time and whether the subsidence patterns change abruptly, we can timely diagnose the observation environment and stability around BDS monitoring stations. This enables rapid analysis and diagnosis of vegetation growth changes and abnormal soil subsidence changes around BDS monitoring stations at a lower manpower cost.

Key words: massive data, BDS deformation monitoring, automation technology, station health diagnosis, middle route of South-to-North Water Diversion Project
