Abstract

The invention discloses a fast deformation monitoring system based on star chain difference and Beidou navigation technology, which includes a user receiver, a ground mobile monitoring reference station and a data processing device. The present invention builds a movable displacement monitoring station, establishes a communication network transmission system, adopts a short message communication mode, and realizes two-way information transmission between the Beidou satellite positioning terminal and the Beidou satellite or the Beidou ground service station; and synthesizes the monitoring data Processing, the ground reference station network receives the original satellite observation data in real time, calculates error correction information, generates wide-area meter-level, decimeter-level, and centimeter-level differential data, and uses online monitoring and early warning terminals to dynamically monitor the deformation trend of slope monitoring points in real time , Generate daily and weekly reports in time to effectively avoid disasters.

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...

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
