AI Technical Summary

Technical Problem

The seabed observation platform of the submarine scientific observation network is easily dragged, displaced, or lost due to fishing activities, and the existing technology lacks effective alarm and location indication means, resulting in low search efficiency.

Method used

A control system, attitude sensors, water outlet positioning beacons, and release devices are installed on the bottom observation platform. The attitude sensors detect abnormalities and release the water outlet positioning beacons after a delay following cable disconnection, providing position indication.

Benefits of technology

It enables timely alarms when damage occurs, improving the time and success rate of locating dragged and bottomed observation platforms, and enhancing search efficiency and success rate.

Abstract

The application provides a mobile alarm and position indicating device for a bottom-lying observation platform, comprising a control system, a posture sensor, a water release positioning beacon and a release device, the control system and the posture sensor are arranged on the bottom-lying observation platform and connected to an observation network, the release device is connected to the control system, the release device releases the water release positioning beacon under the control of the control system, when the underwater bottom-lying observation platform is dragged by external force, the posture sensor detects the abnormality and sends an alarm through the observation network, when the external force continues to drag and destroys the cable connecting the bottom-lying observation platform to the observation network, the control system starts to release the water release positioning beacon after the cable is disconnected, and the position of the bottom-lying observation platform is indicated. The application can alarm when the bottom-lying observation platform is dragged and moved by external force, and can provide position indication when the bottom-lying observation platform is searched after being dragged, so that the efficiency and success rate of searching the bottom-lying observation platform are improved.
