Background

In recent years, the marine transportation industry has become more important with the rapid development of human socioeconomic. In ships sailing on the sea, the ships include both passenger ships and cargo ships, and accompanying the ships are various fire-fighting potential safety hazards. When a fire disaster happens on a ship, the traditional escape mode needs crews to guide passengers to sit on the life raft in sequence according to escape routes, and the escape routes are crowded and blocked due to the fact that most of people are in a panic state and the number of people is large, so that the escape efficiency is low, and the escape effect is poor. And part of passengers in the fire zone can not open the door to go to the escape route due to objective factors such as dense smoke, strong fire and the like, and can only wait for the arrival of rescue personnel in the passenger cabin, but can die due to the fact that timely rescue cannot be obtained.

It can be seen that the escape mode under the condition of a fire of the traditional ship is too single and cannot meet the requirement of safe and effective escape of the masses from a fire scene, and the professional rescue cannot be timely caught from the land because the ship sails on the sea.
