Tailings pond displacement monitoring station - an unforgettable dam safety monitoring station that cannot be omitted in 2024

WX-WY1- Through geological hazard monitoring, we can gain a deeper understanding of the impact of human activities on the geological environment, thereby adjusting our behavior and reducing environmental damage. At the same time, geological hazard monitoring also helps to raise public awareness and protection consciousness of the geological environment, and promote the formation of a good atmosphere for the whole society to participate in geological hazard prevention and control.

1、 Product Introduction

The GNSS monitoring system is based on a satellite positioning system with known spatial positions and adopts the basic principle of space rendezvous to achieve absolute positioning of ground user terminal devices. The receiver terminal deployed on site remotely and wirelessly transmits observation data to the monitoring center (usually cloud based receiving 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 functional division, the entire monitoring system can be divided into three main parts: spatial part, ground reference station part, and monitoring terminal part.
