Maritime emergency position indicating system

Abstract

The invention provides a maritime emergency position indicating system. In the invention, a beacon and a search engine perform wireless communication; when a person carrying the beacon falls into water, the power supply of the beacon can be automatically or manually switched on in the case of falling into water, and then the beacon transmits outwards a wireless distress signal; and when a rescue ship or aircraft equipped with the search engine leaves for an accident location for rescue, the ship or aircraft can search and receive the distress signal transmitted by the beacon in a sea area with the radius of more than 5km along the way, and the search engine can learn the position and approximate distance of the person falling into water and carrying the bean relative to the search engine by adopting a radio positioning technology so as to help search and rescue workers carry out fixed-point rescue. Therefore, the maritime emergency position indicating system provided by the invention has the beneficial effects of overcoming influence on maritime search and rescue in the case of severe weather, accelerating the search and rescue progress and improving the success probability of fixed-point rescue.

Description

technical field [0001] The invention relates to a communication and rescue equipment for maritime emergency search and rescue, in particular to a maritime emergency position indication system. Background technique [0002] According to the relevant regulations of the International Maritime Organization and my country's Maritime Safety Administration, most seagoing ships are equipped with communication and rescue equipment such as VHF radio stations, maritime wireless telephones, GPS positioning systems, and satellite ship stations. In the event of an accident, the ship can call for help from the search and rescue department through these devices. However, after the crew fell into the water, under the action of the current, they would drift away from the accident site. Since the drowning crew basically has no personal communication or position indicating equipment, when the rescuers arrive at the wreck site, they can quickly find the wrecked ship, but it is difficult to dete...

AI Technical Summary

Problems solved by technology

Since the drowning crew basically has no personal communication or position indicating equipment, when the rescuers arrive at the wreck site, they can quickly find the wrecked ship, but it is difficult to determine the exact location of the drowning crew

At present, the rescue methods of search and rescue personnel are backward. They can only infer the position where the person who fell into the water on the ship may have drifted by analyzing the water flow in the wrecked area; search the sea surface through the camera system, lighting system and infrared night vision system, and conduct a dragnet search

In areas with many coastal islands and reefs, the circulation of islands and reefs is complex and changeable, and it is difficult to guess the position of the person who fell into the water; under severe weather conditions, search and rescue are more difficult
