AI Technical Summary
Existing false bottom monitoring systems rely on a single sensor or manual measurement, making it difficult to achieve high-precision, multi-parameter synchronous monitoring. This results in large data errors, affecting the accuracy of the experiment, and lacks intelligent anomaly detection and alarm mechanisms, posing safety hazards.
It adopts six subsystems: power, position, angle, safety, lighting and video monitoring, and integrates monitoring devices, including load sensors, underwater sonar altimeters, current sensors, underwater cameras, etc., to form a full-process, multi-dimensional monitoring system, realizing real-time data acquisition and anomaly early warning.
It enables comprehensive and high-precision monitoring of the rising and falling false bottom, reduces failure rate and maintenance costs, ensures the safety and reliability of the test, and reduces the need for manual inspection.
