Formation path planning method and system for maritime search and rescue

Abstract

The invention provides a formation path planning method and system for maritime search and rescue. The formation path planning method and system is realized through a drift position prediction module, a drift prediction area tracking module and a coverage search path planning module. The drift position prediction module predicts the drift position of a drowning person through a random particle simulation method, and generates a missing person distribution map and a drift prediction area through a step length statistical method; and the shift prediction area tracking module and the coverage search path planning module adopt a self-adaptive greedy search algorithm to track a drifting area of the drowning person and perform coverage search on the drifting area so as to obtain a search and rescue path. According to the formation path planning method disclosed by the invention, the determination of the search and rescue area is combined with the influence of the current marine environment on the drift of the drowning missing person, and the position probability of the drowning missing person and the change of the position probability are considered, so that the planning of the search and rescue path greatly reduces the maritime search and rescue operation time, and the probability that the drowning person is successfully searched and rescued is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of personnel search and rescue, and relates to a search and rescue path planning method and system. Background technique [0002] The sea temperature is low and the sea conditions are complex. People who fall into the water may die due to drowning or hypothermia. Fast and effective search and rescue operations are crucial to ensure the safety of victims [0003] Search and rescue is a systems mission that requires planning, coordination, control and command to respond to emergencies. Search and rescue services consist of two main processes: search is an operation, usually coordinated by a rescue coordination center or sub-centre, to locate persons in distress using dispatchable personnel and facilities; rescue is the removal of persons in distress, meeting their initial medical or other needs and transport them to a safe location. For most emergencies, finding people in distress is a critical part of searc...

Problems solved by technology

However, this search and rescue method still uses the traditional single-ship circular and square search. The planned search and rescue path can only be realized by unmanned boats, and the search and rescue area is covered indiscriminately during the search and rescue process. Rapid search and rescue of those who fell into the water
