Description

Technical Field

[0001] The present invention relates to the technical field of satellite positioning, and in particular to a Beidou maritime emergency position-indicating beacon and a Beidou emergency communication system. Background Art

[0002] An Emergency Position Indicating Radio Beacon (EPIRB) is a device used when a ship encounters an emergency. It can transmit a radio alarm signal to provide identification, location and other information for search and rescue. The EPIRB in the prior art has a built-in integrated GPS receiver, which can continuously update the positioning information to provide accurate positioning even when it is automatically started and floats in the sea. When a ship is in distress and the hull sinks to a certain depth, the hydrostatic pressure of the seawater is measured by the hydrostatic pressure releaser, the release mechanism is automatically started, the position beacon is separated from the bracket or storage box, floats to the surface, and starts to transmit an alarm signal. The EPIRB's distress signal is forwarded to the ground station through the Global Maritime Distress and Safety System (GMDSS), reporting the current position, platform information, etc. Rescue organizations can often arrive at the distressed sea area as soon as possible to carry out rescue work.

[0003] The GMDSS system is a comprehensive global communication search and rescue network designed to improve maritime distress and safety communications. However, despite its wide coverage, there is still a certain waiting time, and its efficiency is still limited by its execution strength, equipment modernization, and compatibility with other rescue systems, which affects the real-time reception and processing of distress signals, causing rescue delays.

[0004] The GPS module is mainly used for positioning and sending distress information. Its function is limited to one-way communication, that is, it can only send information from the GPS device to the outside, and cannot achieve two-way communication. This means that rescue instructions cannot be transmitted to the personnel or equipment in need of rescue in a timely manner through the GPS module, so that rescue instructions cannot be responded to in time, reducing the effectiveness and reliability of rescue.

[0005] The Beidou Navigation Satellite System (BDS) is a global satellite navigation system independently developed by China. It can provide high-precision, high-reliability positioning, navigation, and timing services to all types of users around the world around the clock, and has short message communication capabilities. The 106th meeting of the Maritime Safety Committee of the International Maritime Organization (IMO) (MSC.529) approved the Beidou Short Message Service System (BDMSS) to join the GMDSS system. The Beidou short message two-way communication service is a special service of the Beidou system, which can provide distress alarm positioning, information broadcasting and short message communication services that meet the requirements of the GMDSS. The addition of the Beidou short message service system to the GMDSS will help enrich the global maritime distress and safety communication methods and improve the efficiency of maritime life safety rescue.
