1.Product introduction ofgeological disaster monitoring and early warning system

Geological disaster monitoring and early warning system, also known as natural disaster monitoring and early warning system, landslide monitoring and early warning system, geological disaster monitoring and early warning system can monitor the geological environment in real time, timely detect and provide early warning of various potential geological disaster risks, and provide you with reliable protection. .

The GNSS monitoring system is based on the satellite positioning system with known spatial position and adopts the basic principle of space resection to achieve the absolute positioning of ground user terminal equipment.The receiver terminal deployed on site remotely and wirelessly transmits the observation data to the monitoring center (usually cloud reception and storage) according to the established collection and transmission frequency. The monitoring center analyzes and processes the observation data in real time for use by relevant technical and management departments.

From the perspective of data flow and function division, the entire monitoring system can be divided into three parts: the space part, the ground reference station part, and the monitoring terminal.

5. Installation precautions

1. The air field of view is relatively wide, and there are no obstructions within the height angle of 15° within the field of view.

2. Stay away from high-power radio emission sources (such as TV stations, radio stations, microwave stations, etc.), the distance is not less than 200 meters, and stay away from high-voltage transmission wires and microwave radio signal transmission channels, the distance is not less than 50 meters

3. There should be no strong signal reflecting objects nearby (such as large buildings, large areas of water, etc.)

4. The transportation is relatively convenient, which is conducive to construction, testing and subsequent maintenance operations.

5. The benchmark point measurement and design should be carried out according to the design plan, and its foundation should be guaranteed to be stable.

6. Monitoring point measurement equipment should be implemented according to the design plan. If fine-tuning is necessary, it should be fully communicated with the design unit to determine
