Surface Displacement Monitoring System
The model SDMS surface displacement monitoring system is based on the technology of global navigation satellite system. The SDMS using highly integrated design, it is based on a high-precision multi-system board and can provide high-precision positioning. The integrated design improves the system's anti-interference and reliability. It is widely used in surface displacement monitoring in bridges, slopes, reservoirs, dams, earthquake disasters and other industries. The device has built-in GPRS\3G\4G communication module and data transmission unit. It integrates 30AH high-capacity lithium battery and solar power supply system. You just only need to connect external solar panels to the SDMS. The SDMS can be widely used for surface displacement monitoring and structural deformation monitoring, such as real-time monitoring of displacement and deformation of landslides, slope displacements, bridge deformations,reservoirs, dams, mines, geological disasters, etc.
Overview
Global Navigation Satellite System(GNSS), which generally refers to all satellite systems, including global and regional satellite navigation systems such as China's Beidou System (BDS), the United States GPS system, the Russian GLONASS system and the European Galileo system. The GNSS has the advantages of all-weather, full-time domain, high positioning accuracy, short measurement time, no need for visual communication between measuring stations, and the ability to simultaneously measure the three-dimensional coordinates of points. GNSS technology is a high-precision deformation monitoring technology that enables remote automated measurement.
● Adopt dual-system (GPS, BDS) high-precision board, which can be used for single-system positioning or multi-system combined positioning, or combined RTK positioning
● Highly flexible split design, suitable for deformation monitoring, network reference station, driving test system, mechanical control and other system sets
● Using AutoBase technology, the configuration of the reference station can be quickly realized when the machine is turned on
● Reserved Ethernet, GSM/GPRS, LORA communication
● Support PJK plane coordinate output, no need for third-party software to do projection conversion
● Support automatic differential, differential format support RTCM2.X, RTCM3.X
● Internal storage of 100M, can be set to automatically record the original data
● Building displacement settlement monitoring
● Slope displacement and settlement monitoring
● Bridge displacement settlement monitoring
● Displacement and settlement monitoring of water conservancy dam
