Edge AI-Based Gas Leak Detection and Remote Control System

Shipyard Gas Safety System with Edge AI Pipeline Monitoring for Automatic Valve Shutoff During Leaks

This technology is a gas leak detection and remote control system that installs flow and pressure meters on underground shipyard gas pipelines. It connects receiving devices that collect sensor data, edge AI-based processing devices, and a control server via communication links to remotely detect gas leaks and immediately shut off valves.

Shipyards supply gases such as oxygen, CO2, argon, and LPG for welding through underground pipelines. Previously, this relied on manual checks of analog gauges, leaving no way to quickly identify leak locations or gas flow. Existing monitoring devices only recorded valve operation counts for periodic inspection, making accurate leak diagnosis difficult and creating a risk of explosion due to delayed emergency responses.

In this system, the processing device's leak detection unit identifies leaks based on flow and pressure data, triggering the valve control unit to close the pipeline valve. The control server then issues alarms, enables camera-linked monitoring, and establishes accident response strategies. The receiving device is slide-fixed with a spring-loaded plate inside a symmetrical coupling structure that fits around the pipe, while a hinged extension plate and elastic straps absorb external shocks. Applicable to shipyard welding gas supply networks, petrochemical and power plant pipelines, and industrial complex gas infrastructure, this system eliminates the need for manual gauge checks, automatically cutting off gas during a leak and allowing immediate on-site verification from the control room.

Key Features:

• A receiving device that collects sensor data from flow meters detecting gas flow and pressure gauges measuring internal pipeline pressure
• A processing device that determines gas leaks based on the received data and controls the closure of pipeline valves upon detection
• A control server that receives leak detection results to trigger visual and audible alarms, enable camera-linked monitoring, and establish accident response strategies
• A symmetrical coupling structure that allows pipe passage, secures the receiving device via a spring-loaded slide, and mitigates external impact
