Intelligent auxiliary decision-making platform and decision-making method for emergency evacuation of large passenger ship

Abstract

The invention provides an intelligent auxiliary decision-making platform for emergency evacuation of a large passenger ship, and the platform comprises a data attribute collection module, a machine data interaction module, and an emergency plan virtual simulation platform which comprises a virtual mapping module, a fire/smoke dynamic simulation module, a man-machine interaction correction module,and an intelligent decision-making output module. The decision-making method comprises the following steps: realizing acquisition and transmission of attribute data through an Internet of Things technology and/or 5G communication; simulating the dynamic change trend of fire, smoke and toxic gas through CFD simulation software; manually confirming a simulation result through VR simulation; combining a GIS technology and a system engineering theory, and outputting a multi-objective optimized intelligent emergency evacuation scheme; according to the invention, artificial intelligence, virtual simulation, digital twinning, 5G communication and Internet of Things technologies are combined, so that the system has functions of remote identification, intelligent simulation, multiple control and intelligent decision making.

Description

Technical field[0001]The invention relates to the technical field of emergency management, in particular to an intelligent auxiliary decision-making platform and a decision-making method for emergency evacuation of large passenger ships.Background technique[0002]Passenger ship tourism is an emerging industry with huge development potential. Its market share is increasing year by year, and it has shown a much higher level of overall development than the international tourism industry. However, passenger ship accidents have occurred frequently in recent years, which has seriously hindered the development of the industry. Especially after the investigation of many water accidents in recent years, it is found that on-site order, personnel psychology and external guidance are the keys to emergency evacuation. Therefore, at this stage, can we provide passengers with correct evacuation guidance in the face of emergencies and prevent secondary accidents? The occurrence of emergency evacuati...

[0002] Passenger ship tourism is an emerging industry with great development potential. Its market share is increasing year by year, and it has shown a level of development far higher than that of the international tourism industry. However, passenger ship accidents have occurred frequently in recent years, which has seriously hindered the development of the industry. Especially after the investigation of many water accidents in recent years, it was found that on-site order, personnel psychology and external guidance are the key to emergency evacuation. Therefore, at this stage, can passengers be given correct evacuation guidance in the face of emergencies to prevent secondary accidents? to improve the efficiency of emergency evacuation has become an important research topic to improve the safety and emergency response capabilities of passenger ships

[0003] Invention patent 201910751569.4 provides a method for predicting atmospheric diffusion based on CFD simulation technology, but does not answer the emergency evacuation plan; invention patent 201911021687.6 provides an emergency evacuation method based on digital twin technology, but this method only passes CAD drawing and GIS technology are used to build 3D models, and video surveillance is used to detect the physical world, which cannot be recognized in real time in a smoky space, and does not take into account the impact of external factors on evacuation; the invention patent 201711392966.4 is based on the measured The behavior of the person in the VR space is collected to realize the formulation of the emergency evacuation plan, but the plan cannot deal with the evacuation in an environment that changes in real time.
