Description
technical field [0001] The invention relates to the technical field of deformation monitoring, in particular to a Beidou-based deformation monitoring system and method. Background technique [0002] In the existing slope deformation monitoring, GPS is generally used for deformation monitoring. The usual solution is to transmit the original monitoring data to the data center in real time for centralized data processing. However, signal transmission in mountainous areas with poor network is limited, and due to GPS The monitoring accuracy and stability are poor, so higher-precision post-processing results are generally used for monitoring and early warning, and real-time landslide early warning cannot be performed on site. It takes a long time from the data transmission to the server, to the server's calculation to obtain high-precision post-event results, and then to the manual sending of early warning notices, which is not conducive to the monitoring of sudden landslides. In...
