Description

Technical Field

[0001] This utility model relates to the field of structural deformation monitoring technology, and in particular to an integrated multi-parameter GNSS receiver. Background Technology

[0002] Current GNSS measurements used for geological disaster and structural monitoring are single-parameter measurements, capable only of measuring deformation and unable to perform multiple monitoring functions. However, current industry demands require monitoring multiple parameters, such as cracks, rainfall, and environmental measurements. To meet actual field requirements, the traditional approach is to integrate separate monitoring equipment, involving on-site wiring integration, which is costly and complex in construction and maintenance.

[0003] Furthermore, traditional GNSS receivers cannot directly provide on-site early warnings or link with audible and visual alarms; they only monitor data and cannot provide early warning prompts, resulting in incomplete functionality. To achieve alarm functionality, a remote control terminal can be added, with the platform triggering the linkage, but this will affect timeliness.

[0004] Furthermore, traditional GNSS receivers typically use discrete photovoltaic power supply systems, which are complex to maintain. Utility Model Content
