gnss deformation monitoring system and implementation method based on active-active data center

Abstract

The invention provides a GNSS deformation monitoring system based on an active-active data center. The system comprises a reference station, a post-treatment solving system and a deformation monitoring terminal. The post-processing solving system is connected with the reference station and the deformation monitoring terminal, and comprises a main post-processing solving system and an active-active post-processing solving system. The main post-processing solving system comprises a main reference station access module, a main system database and a main post processing solving module. The main reference access module is connected with the reference station. The main system database is connected with the main reference station access module and the main post processing solving module. The active-active post-processing solving system comprises an active-active reference station access module, an active-active system database and an active-active post processing solving module. The active-active reference station access module is connected with the reference station. The active-active system database is connected with the active-active reference station access module and the active-active post processing solving module. According to the invention, compared with a scheme based on a host backup data center, the accessed terminals are doubled and the system efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of satellite positioning and navigation, in particular to a GNSS deformation monitoring system based on an active-active data center and an implementation method. Background technique [0002] GNSS (Global Navigation Satellite System, Global Satellite Positioning System) has been widely used in various fields such as navigation and positioning since it was put into civilian use in the mid-1980s, and has played an epoch-making role in the control and measurement of the surveying field. Because of its advantages in relative positioning, such as high precision, high efficiency, all-weather, and no need for vision, people generally use it to replace conventional methods such as triangles, three sides, and corners, and have achieved great results in theory and practice. gratifying results. It has also been widely used in precision engineering deformation monitoring. [0003] Deformation monitoring (deformation ...
