Improved emergency position indication radio beacon

Abstract

The invention discloses an improved emergency position indication radio beacon, which is used for emergency rescue of ship at sea. The whole improved emergency position indication radio beacon comprises a communication module, a global positioning system (GPS) module and a Beidou satellite positioning module, which are connected with a central processing unit (CPU) master control module, and a power supply module. When a ship distress device breaks away from the ship, the emergency position indication radio beacon can automatically acquire precise position information through the GPS module and the Beidou satellite positioning module, and the CPU master control module controls the communication module to transmit a distress signal. The communication module sends an alarm message in a 406MHz satellite communication frequency band and sends the distress signal. The Beidou satellite positioning module can send an alarm signal through a short message communication alarm function of a Beidou system. Due to the arrangement of the GPS module and the Beidou satellite positioning module, the positioning precision is improved. As the improved emergency position indication radio beacon integrates multiple alarming methods, rescue ships or airplanes can find the ship in distress rapidly, and the rescue speed is improved.

Description

technical field [0001] The invention relates to an electronic signal transmitter of maritime wireless communication and navigation equipment, in particular to an improved emergency radio position indicator. 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 Glob...

Problems solved by technology

[0009] In view of the above problems, the present invention provides an improved emergency radio position indicating sign, which uses the 406MHz satellite communication frequency band to transmit alarm information, and uses the GPS satellite positioning system and the Beidou satellite positioning system to obtain the position information, and the two work together to obtain the position information. At present, the ship-borne emergency radio position-indicating beacon has a large positioning error problem, and the alarm can be sent through the short message communication function of the Beidou satellite positioning system
