Problems solved by technology

[0008] Traditional slope monitoring methods mainly rely on manual or semi-manual methods. By arranging certain sensors or instruments on site, and then manually processing data and analyzing the monitoring results, the entire monitoring process requires a lot of manpower and material resources, and it is difficult to To achieve real-time data processing, there is often a large delay in monitoring results, so there are problems such as slow time efficiency, low accuracy, and high cost. Installed on a stone pier, if a large-scale disaster occurs, it will take a long time to dismantle the mobile base station and cannot be transferred in time

Abstract

The invention discloses a rapid deformation monitoring system based on star chain difference and Beidou navigation technology. The system comprises a user receiver, a ground mobile monitoring base station and a data processing device. According to the invention, by constructing a movable displacement monitoring station, establishing a communication network transmission system and adopting a shortmessage communication mode, bidirectional information transmission between a Beidou satellite positioning terminal and a Beidou satellite or a Beidou ground service station is realized; the monitoringdata is comprehensively processed; a ground reference station network receives satellite original observation data in real time, error correction information is calculated, wide-area meter-level, decimeter-level and centimeter-level differential data is generated, an online monitoring and early warning terminal is used for dynamically monitoring the deformation trend of a slope monitoring point in real time, daily reports and weekly reports are generated in time, and disasters are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of deformation monitoring, and in particular relates to a fast deformation monitoring system based on starlink difference and Beidou navigation technology. Background technique [0002] The development and application of Global Positioning System (GPS) technology has promoted a major historical change in surveying and mapping technology, and fundamental changes have taken place in surveying and mapping from theory to means. Especially in the past 10 years, GPS surveying and mapping technology has developed rapidly, and has completed the transformation from static positioning technology to dynamic positioning technology, from RTK technology to global differential positioning technology. [0003] Global differential positioning technology uses differential GPS technology. The system will obtain the latest error correction information from geosynchronous orbit communication satellites, and inject the correction...
