AI Technical Summary

Technical Problem

Existing bank collapse monitoring technologies suffer from poor communication in complex underwater environments, resulting in low monitoring efficiency and poor real-time performance, which fails to meet the needs of dike safety.

Method used

A sensor system combining IMU and GNSS, along with a Kalman filter algorithm, is used to transmit data in the underwater environment via an underwater transducer and then switch to 5G communication on the surface, forming a multi-media fusion monitoring system.

Benefits of technology

It has enabled stable and real-time monitoring of bank and embankment displacement in both above-water and underwater environments, improving the accuracy and reliability of monitoring, providing real-time early warning capabilities, and offering important data support for flood control and embankment safety.

Abstract

Aiming at the complex situations of low water seasons, high water seasons and daily water line change, double-scene adaptation can be realized, the displacement condition of the embankment can be monitored in real time, the overall attitude information of the system can be sensed, the longitude and latitude position change can be detected, and the underwater displacement measurement data can be acquired. The system is provided with two sets of independent communication units which are respectively suitable for underwater and overwater scenes, the underwater transducer can efficiently transmit data acquired underwater to the water surface, the 5G communication unit realizes real-time interaction with a shore workstation, and the adaptability and reliability of the system in different environments are ensured. The system can analyze and process sensing signals in real time, early warning information can be sent out in time before displacement abnormity or bank collapse risks occur on the embankment, sufficient response time is provided for related departments, and the disaster prevention capacity is remarkably improved.
