Improved EPIRB (Emergency Position Indicating Radio-Beacon)

Abstract

The invention discloses an EPIRB (Emergency Position Indicating Radio-Beacon) device used in offshore vessel emergency rescue. The device is composed of an EPIRB floating body and an autoinflation communication balloon and internally consists of a power supply module, a main control module, a GPS (Global Positioning System) receiving module, a signal transmitting module, a signal receiving module and an autoinflation device, wherein the floating body transmits alarm information at a 406MHz satellite communication frequency band; the communication balloon is internally integrated with the signal transmitting module and the signal receiving module which are connected with the main control module; the receiving module is used for receiving UHF (Ultra High Frequency) band signals transmitted by portable sub beacons of adjacent shipmen, and determining the quantity and position information of the adjacent shipmen; and the signal transmitting module transmits distress signals at a VHF (Very High Frequency) band in a wireless manner. The EPIRB is mainly designed for middle and small vessels; when a vessel is in danger, the EPIRB is automatically released after falling into water, and then floats away from a vessel body; the communication balloon auto-inflates and floats in the air to transmit a distress signal, and is connected with the EPIRB floating body by virtue of a nylon rope; and the spherical body of the balloon is orange, so that search-and-rescue personnel can determine the positions of the adjacent shipmen conveniently. The device has the characteristics of improving the rescue speed, ensuring the rescue reliability and protecting the safety of rescued personnel to the greatest extent.

Description

technical field [0001] The invention relates to an electronic signal transmitter of maritime communication and navigation equipment, in particular to an improved emergency radio position indicating sign. Background technique [0002] According to the United Nations: In 1982, three people who were in danger on a Canadian plane were successfully rescued for the first time. From 1982 to 1997, 8,638 people were successfully rescued. In 1997, the system was activated 1,284 times, and 1,284 people were successfully rescued. According to statistics from our country: from 1982 to 1999, 3361 alarms were received worldwide, and 11227 people were rescued. [0003] Emergency Position Indication Radio Beacon (EPIRB for short) is a beacon that can emit radio signals. It uses the radio frequency signals emitted by itself to indicate its position and status, so that search and rescue units can accurately determine its position. It is an important ship-to-shore warning device in the Global ...
