Wuhan Zhongdi Hengda -- GNSS Surface Displacement Monitoring System
System Introduction
The GNSS automatic monitoring system is a displacement monitoring method for the horizontal and vertical directions of the monitored object. It can effectively analyze the displacement and deformation trend of the monitored object, achieving the purpose of prevention and early warning.
The GNSS automatic monitoring system adopts high-precision deformation monitoring data processing algorithms, which can obtain millimeter-level real-time deformation monitoring accuracy, allowing users to grasp the instantaneous deformation of the monitored object in real time and meet their needs for real-time understanding of the instantaneous deformation of the monitored object.
The GNSS receiver uses GNSS technology to continuously, automatically and real-timely collect monitoring data of the monitored object, sends the data to the data processing center via a communication link for high-precision data processing and analysis, and then uploads the data results to the Web server, enabling users to understand the real-time deformation of the monitored object anytime and anywhere through terminals such as computers and mobile phones.
