Drowning target search and rescue method and system with self-searching function

Abstract

The invention relates to a drowning target search and rescue method and system with a self-searching function. The method comprises the following steps: step S1, a search and rescue task demand is received, and the search and rescue task is started; step S2, a rapid search and rescue system is thrown into a to-be-searched area after arrival over the to-be-searched area; step S3, the rapid search and rescue system is deployed after landing on water, a USV (unmanned surface vessel) and a vessel-borne multi-sensor fusion search and positioning system are started, and a lifesaving floating platform follows up; step S4, the vessel-borne multi-sensor fusion search and positioning system detects and searches the position of a person overboard and outputs unified target position information to a USV control mechanism; step S5, the USV control mechanism formulates and executes a route plan according to the target position information in combination with own position, and the USV drags the lifesaving floating platform to arrive at the position of the person overboard; step S6, the person overboard climbs onto the lifesaving floating platform and waits for rescue, and the task is completed. The system is based on the method. The method and the system have the advantages of being easy to realize, good in timeliness, wide in rescue range and the like.

Description

technical field [0001] The invention mainly relates to the field of search and rescue methods, in particular to a search and rescue method and a search and rescue system for a falling target with a self-seeking function, and is especially suitable for rescue operations of COSCO SHIPPING. Background technique [0002] With the improvement of my country's economic level, the transformation of military strategy and the development of the marine economy, the comprehensive national strength has been significantly enhanced, and the fields covered by various industries are constantly expanding. Gradually increase. It has become the norm for our fishing operation scope to break through the first island chain. Various types of aircraft are increasingly operating at sea, and the probability of emergencies in complex environments (especially COSCO Sea) increases, and relevant personnel will face harsh living conditions. Therefore, the rapid rescue capability in COSCO SHIPPING environme...

AI Technical Summary

Problems solved by technology

[0006] 1. The search and rescue radius of helicopters is small, the range is short, and the speed is slow, so it is difficult to achieve fast search and rescue. The current sea surface search and rescue is mainly based on visual inspection, coupled with visual fatigue, bad sea conditions and other factors, the search and rescue effect is poor; my country's current sea surface rescue aircraft Less, slow speed, difficult to quickly reach the designated operating area, small range, limited operating radius

[0007] 2. Ship search and rescue is slow and time-sensitive, and cannot reach the search and rescue area quickly

[0008] 3. It is very easy to exceed the golden rescue time period, which will reduce the chance of rescue of people who fall into the water

[0009] 4. The ability to adapt to harsh sea conditions is weak. Taking helicopters as an example, in level 4 sea conditions, the risk of search and rescue operations increases, and the efficiency of search and rescue is poor.
