Problems solved by technology
[0007] 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

The invention discloses a fast deformation monitoring system combined with a Starlink differential system and a Beidou ground-based augmentation system. The system includes a data acquisition subsystem, a data analysis subsystem, a data processing center subsystem and a user subsystem. In the present invention, a mobile reference station is established near a point with a large slope shape variable, and a data acquisition subsystem with star-link differential technology is placed on a tripod that can be quickly disassembled, and the level bubble is used for adjustment, and the short-message The communication method transmits the Beidou data to the data processing system, and finally to the Beidou positioning terminal monitoring system, and monitors the deformation trend of the slope monitoring point through the monitoring system, and timely warns. It has the advantages of simple structure, low cost, detachable, and installation time. Short and other advantages, it can quickly transfer the mobile reference station, and can improve the positioning accuracy of Beidou navigation.
Description
technical field [0001] The invention belongs to the technical field of deformation monitoring, and in particular relates to a fast deformation monitoring system combined with a Starlink differential and a Beidou ground-based augmentation system. 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...
