The JCZD monitoring terminal is an industrial-grade high-precision GNSS monitoring device developed based on static GNSS differential technology. It achieves ±2.5 mm horizontal and ±5 mm vertical accuracy, making it ideal for real-time monitoring of micro-displacement and settlement in harsh outdoor conditions.
It is widely deployed in:
-
Landslides & geological hazards
-
Mining slopes & open-pit deformation
-
Oil tank settlement
-
Dam & reservoir embankment settlement
-
Roadbed displacement monitoring
-
High-precision structural monitoring
With its aluminum alloy housing, IP67 protection, GNSS fusion algorithm, and stable 4G/RJ45 communication, the device supports long-term 24/7 unattended operation.
System Architecture Overview
1. GNSS Data Acquisition
Each JCZD terminal continuously receives multi-constellation GNSS satellite signals (GPS, Beidou optional, GLONASS).
2. Differential Positioning
Using static GNSS differential technology, the system corrects GNSS errors through:
-
Internal fusion algorithms
-
Optional reference base station
-
Multi-system satellite correction data
3. Communication Layer
Data can be transmitted through:
-
4G Full Netcom (built-in SIM)
-
RJ45 Ethernet
Ensuring real-time communication between terminals and cloud servers.
4. Cloud Monitoring Platform
The backend server performs:
-
Fusion positioning
-
Multi-point settlement analysis
-
Trend prediction
-
Data visualization
-
Early-warning alarms
5. Monitoring Deployment Modes
The system supports:
-
Single-point vertical settlement
-
Multi-point cross-section displacement
-
Multi-terminal networked monitoring
-
Solar-powered remote deployments
