Design and Experiment Verification of Gas Leak Monitoring System for Underwater Structure

Based on the principle of accurate prediction and prevention, a gas leakage monitoring system for underwater structures based on underwater acoustic detection and identification technology is designed. The system detects and acquires abnormal sounds of gas leakage from underwater structures, extracts the characteristics of underwater acoustic signals, and automatically identifies and estimates the orientation and leakage. The system realizes online, real-time monitoring and alarming of gas leakage faults in underwater structures. The monitoring radius is not less than 200m, and the leakage location error is not more than 5%.
