基于船舶火灾蔓延态势的路径规划算法研究

船舶作为海上一个独立的建筑实体,非常容易发生火灾。本文以63500DWT油船船舱作为研究对象,通过对火灾蔓延模拟仿真实验数据进行图表分析,得出了在不同工作条件下在固定检测点位置的温度,CO浓度和烟气浓度变化规律。对基于火灾实时态势的导航网格动态生成方法以及对应的逃生路径规划方法进行研究,得出动态更新导航网格的具体算法,并对传统A*算法路径节点选择问题进行改进,得出适应船舱火灾蔓延信息的最短逃生路径规划算法,通过实验验证,该算法寻路效率更优。

Research on Path Planning Algorithm Based on Ship Fire Spreading Situation

The ship is an independent construction entity at sea and is very prone to fire. This article takes the cabin of the 63500DWT oil tanker as the research object, through graphical analysis of the fire spread simulation experiment data, the law of temperature, CO concentration and smoke concentration change at a fixed detection point under different working conditions is obtained. Research on the navigation grid dynamic generation method based on the real-time fire situation and the corresponding escape route planning method, get the specific algorithm for dynamically updating the navigation grid, the traditional A* algorithm path node selection problem is improved, and the shortest escape path planning algorithm that adapts to the cabin fire spread information is obtained. Through experimental verification, the algorithm obtained has better path finding efficiency.
