Overwater fast life-saving device and system

Abstract

The invention discloses an overwater fast life-saving system. The system comprises an overwater fast life-saving device, multiple signal receivers, a controller and multiple automatic life-saving equipment releasing devices, wherein the overwater fast life-saving device is worn on the body of a person on a boat and used for transmitting wireless signals through a wireless signal transmitter in the device when the wearer falls into water; the multiple signal receivers are distributed around a boat body and used for receiving the wireless signals respectively, acquiring corresponding RSSI (received signal strength indication) values and transmitting the values to the controller; the controller is used for acquiring the value of the distance between the overwater fast life-saving device and each signal receiver according to the corresponding RSSI value so as to acquire the direction of the person falling into water, acquire the automatic life-saving equipment releasing device nearest to the person falling into water and transmits a control signal to the nearest automatic life-saving equipment releasing device; the multiple automatic life-saving equipment releasing devices are distributed around the boat body and used for releasing life-saving equipment in the automatic life-saving equipment releasing devices into water according to control signals. With the adoption of the system, the direction of the person falling into water can be acquired rapidly, and the life-saving equipment can be released rapidly, so that the person falling into water can be saved timely.

Description

technical field [0001] The invention relates to a lifesaving system, in particular to a water fast lifesaving device and a lifesaving system for quick rescue on water, especially at sea. Background technique [0002] When the ship is running on the water, due to various reasons, the phenomenon of people on board falling into the water will occur, such as accidentally falling into the water, falling into the water by slipping and so on. If the person who fell into the water cannot be rescued in time, the person who fell into the water may be in danger of drowning; even if he is not drowning, the human body is not suitable for soaking in water for a long time, especially in cold weather or when the night is colder, it will frostbite the body tissue, which is harmful to the body. Inevitable damage to the human body; and in extremely hot weather, those who are exposed to the water surface for a long time are also prone to heat stroke or exhaustion.

Problems solved by technology

But because personnel often forget to wear the lifesaving belt, cause accident hidden danger

Moreover, the crew on board cannot be notified of the situation of a person falling into the water in time, and the person who falls into the water cannot be rescued in time.
