The Beidou high precision geological disaster monitoring system based on RTK edge calculation and its application analysis

  • 摘要: 为提供全天候、全自动化、高精度变形监测服务,并最大限度降低空间环境因素对实时高精度定位的影响,基于数字调频广播(CDRadio)RTK(载波相位差分技术)边缘计算技术融合GNSS(全球卫星导航系统)核心解析算法,开发了具有自主知识产权、结构开放的“基于广播RTK边缘计算的北斗高精度地质灾害监测系统”,该系统能长时间稳定运行,并能满足功能性需求和非功能性需求在内的所有用户需要。以广西梧州市长洲区宝石园8号地块不稳定斜坡为例,通过分析2020年5—11月的监测数据表明:整个坡体处于蠕变阶段,坡顶前缘有向外侧蠕动且下沉的趋势,整个坡体有向东南方向倾斜发育的趋势。系统通过建立良好的系统信息交互平台,将系统形成的统计分析信息高速便捷地传递给用户,提高用户系统管理、决策、应用能力;充分挖掘系统数据资源,提供实时预报服务,提高信息采集、传输、处理、分析、预报的准确性、可靠性,全面提高地质灾害监测预警预报管理能力,更好地为各级管理部门的决策和指挥抢险救灾提供科学依据。
