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。
To provide service of all-weather,full automation and high precision deformation monitoring and to furthest reduce the effects of space environment factors on the high precision real-time positioning,on the digital CDRadio edge of RTK GNSS core analytic computing technology fusion algorithm is used,and“the Beidou high-precision geological disaster monitoring system with edge calculation based on broadcasting RTK”is developed,which is characterized by the independent intellectual property rights and structure open.The system can run stably for a long time,and can satisfy the functional requirements and non-functional requirements of all users.Taking the unstable slope of block 8 in the Gemstone Garden in Changzhou District of Wuzhou as an example,the monitoring results from May to November 2020 are analyzed.The monitoring data show that the whole slope body is in the stage of slow development,and the front edge of the slope top has a tendency of peristatically moving and sinking.The whole slope body tends to develop towards the southeast direction.Through the establishment of a good system information interaction platform,the statistical analysis information formed by the system is transmitted to users in a high speed and convenient way,which effectively improves the users'system management,decision-making and application ability.It can fully mine the data resources of the system,provide real-time forecasting services,effectively improve the accuracy and reliability of information collection,transmission,processing,analysis and forecast,comprehensively improve the ability of geological disaster monitoring,early warning and forecast management,and better provide scientific basis for the decision-making and command of management departments at all levels in emergency rescue and disaster relief.
