AI Technical Summary

Technical Problem

In the complex disaster environment of ships, the existing technology fails to effectively consider the coupling influence of multiple factors such as hull tilt, fire visibility and personnel load fatigue, insufficient research on the changes in the walking speed of rescue personnel, resulting in difficulty in analyzing, evaluation and optimization of rescue processes.

Method used

A ship fire operation response time evaluation system is built under the multi-factor coupling effect, and by calculating the impact of factors such as ship sway, visibility, personnel fatigue and comprehensive quality on walking speed, a personnel walking speed model is established, and the route with the shortest rescue time is selected as the best rescue path.

Benefits of technology

It provides a scientific path choice for ship rescue, improves rescue efficiency, and ensures that firefighters quickly and safely reach the fire source point in complex environments.

Abstract

The invention relates to a ship fire-fighting operation response time evaluation system under a multi-factor coupling effect. Comprising the following steps: acquiring a personnel walking speed attenuation proportion under the influence of ship rolling, a personnel walking speed attenuation proportion under the influence of ship trim / heeling, a personnel walking speed attenuation proportion under the influence of visibility reduction and a fireman load fatigue walking speed attenuation proportion; based on the speed attenuation difference correction coefficient eta of the fire-fighting operation personnel compared with ordinary people calculated based on the comprehensive quality of the firefighters, the walking speed attenuation proportion under a specific path, and all rescue routes from a fire source point to a rescue starting point; according to the attribute of each branch path on each rescue route and the state attribute of the ship, calculating the walking speed of the firefighters on the branch paths; respectively calculating the rescue time of each rescue route; the rescue route with the shortest rescue time is selected as the optimal water ship fire rescue route; according to the invention, support can be provided for related research of ship rescue operation.
