GNSS Automatic Monitoring Station: Millimeter-Level Real-Time Deformation Monitoring and Disaster Warning Solution

In the field of large-scale infrastructure safety monitoring and geological disaster prevention, traditional monitoring methods are difficult to meet the needs of all-weather, automated, and high-precision displacement tracking. Nexisense GNSS automatic monitoring station is based on Global Navigation Satellite System (GNSS) technology, continuously monitors the displacement of the monitored body in horizontal and vertical directions, and achieves millimeter-level real-time deformation perception through high-precision deformation data processing algorithms, providing reliable prevention and early warning data support for slopes, bridges, dams, tailings ponds and other projects. The system adopts an integrated design, combined with multi-communication methods and low-power supply solutions, to meet the requirements of long-term unattended operation in complex environments, and is widely used in water conservancy, transportation, mining and municipal B2B engineering projects.

Product Overview and Working Principle

GNSS automatic monitoring station is an automated monitoring method for the displacement of the monitored body in horizontal and vertical directions, which can effectively analyze deformation trends and achieve prevention and early warning in advance. The system uses a high-precision GNSS receiver to continuously, automatically and real-time collect satellite signal data, performs high-precision solution through advanced multi-system real-time deformation monitoring algorithms, and uploads the results to the data processing center or Web server via communication link. Users can grasp the instantaneous deformation of the monitored body at any time through computers, mobile phones and other terminals.

The core workflow includes: GNSS receiver receives multi-frequency satellite signals → high-precision RTK solution and deformation algorithm processing → remote data transmission → cloud platform or local system performs trend analysis and threshold alarm. This design effectively makes up for the limitations of traditional manual or single-sensor monitoring and provides millisecond-level response and millimeter-level accuracy.

Typical Application Scenarios

Nexisense GNSS automatic monitoring station is widely used in engineering and disaster prevention projects that require high-precision displacement monitoring.

In the field of geological disaster early warning, the system is deployed at key locations of potential landslide bodies or slopes, real-time captures millimeter-level creep trends, and achieves early warning through threshold alarms to assist disaster prevention and mitigation decision-making.

In water conservancy dam safety monitoring, monitoring stations are installed at key sections of the dam body, continuously track horizontal and vertical displacement, and comprehensively evaluate structural stability in combination with seepage pressure and other data.

In transportation infrastructure, it is suitable for health monitoring of bridges, tunnels, and high slopes, timely detecting minor deformations caused by vehicle loads, temperature changes or geological effects, and ensuring operational safety.

In addition, in tailings ponds, mine goafs, urban ground subsidence and large building structure health monitoring scenarios, the system supports distributed multi-point deployment, with data uniformly aggregated to the cloud platform to achieve visual trend analysis and intelligent early warning. In actual projects, similar GNSS monitoring stations have been successfully applied in southwest mountain highway slopes, Yangtze River basin dams and many geological disaster points, significantly improving monitoring coverage and response efficiency.

Selection Guide

To match specific project needs, purchasers can refer to the following selection points:

  1. Monitoring accuracy and frequency: Select millimeter-level solution accuracy and appropriate data update rate according to engineering risk level; higher sampling frequency is recommended for high-risk areas.

  2. Communication method: Prefer 4G in areas with good signal; extend LoRa or NB-IoT in remote or densely multi-point scenarios; combine with gateway for self-networking.

  3. Power supply scheme: Use solar panel + battery combination in areas with sufficient solar energy; switch to hybrid power supply when mains power is available to ensure long-term endurance.

  4. Installation environment: Evaluate on-site temperature, humidity, lightning protection needs and bracket height, and select IP67 protection and lightning protection configuration.

  5. Platform integration: Confirm docking requirements with existing monitoring automation platforms or SCADA systems, supporting remote parameter configuration and data format adaptation.

Provide project working conditions (monitoring object, environmental conditions, data transmission requirements, number of points, etc.), and the technical team can recommend optimized configuration solutions.

Integration Considerations

The GNSS automatic monitoring station design focuses on engineering integration convenience and supports rapid deployment and system docking.

  • Installation points: The integrated bracket is fixed on stable bedrock or structures to ensure open sky view and no obstruction; bracket height and angle are adjusted according to monitoring needs.

  • Communication integration: Supports TCP/IP, MQTT, Ntrip and other protocols, and can be directly connected to cloud platforms or local servers. When extending LoRa, a gateway is required to achieve multi-station networking.

  • Power management: Solar charging circuit and power controller automatically optimize energy consumption and remotely monitor power status; low-power mode supports ultra-long operation.

  • Data processing and alarm: Use built-in algorithms for real-time deformation solution and set multi-level thresholds to achieve automatic alarms. Support local caching during network abnormalities and retransmission after recovery.

  • Maintenance suggestions: IP67 protection reduces daily maintenance; regularly check solar panel cleanliness and battery status; remote parameter configuration function reduces on-site intervention frequency.

In complex projects, multi-source data fusion can be achieved by combining InSAR or other sensors to improve monitoring comprehensiveness.
