Space-based maritime search and rescue information fusion processing device and processing method

Abstract

The invention discloses a space-based maritime search and rescue information fusion processing device and a processing method. The device is arranged on a satellite-borne platform and comprises a processor, a search and rescue signal receiver, an AIS receiver and a memory. The processor is respectively connected with the search and rescue signal receiver, the AIS receiver and the memory. The search and rescue signal receiver is used for receiving and analyzing a search and rescue position indicating signal sent by the maritime search and rescue object and sending an analysis result of the search and rescue position indicating signal to the processor. The AIS receiver is used for receiving an AIS message of the offshore ship and sending the AIS message to the processor. A ship database containing marine ship information is stored in the memory, and the processor is used for carrying out fusion processing on the analysis result, the AIS message and the ship database so as to identify theoffshore ship meeting the set condition. According to the processing device and the processing method, the offshore ship meeting the search and rescue requirements can be directly extracted on a satellite in real time, the search and rescue scheme and the determination and scheduling time of the search and rescue strength are effectively shortened, and timely rescue is guaranteed.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a space-based maritime search and rescue information fusion processing device and processing method. Background technique [0002] Due to the complex and changeable marine environment, the occurrence of marine accidents is sudden and catastrophic; at the same time, due to the vast sea area and inaccessible people, there is no reference or reliable environment. It will change at any time with the ocean current, which will lead to a sharp increase in the difficulty of maritime search and rescue. [0003] Due to the wide coverage of satellite sending and receiving signals and not subject to geographical restrictions, the satellite search and rescue system (Search and Rescue, SAR) is usually used to carry out maritime search and rescue. The object directly establishes a connection to achieve the purpose of quickly determining the location of the search and rescue obj...

AI Technical Summary

Problems solved by technology

[0006] When carrying out maritime search and rescue work, all kinds of effective information obtained by satellites need to be transmitted to the ground search and rescue command center through the satellite-ground link, and then unified and integrated after being collected to the ground search and rescue command center. There are many transmission link nodes in this process. The link is long and takes a long time, which will reduce the timeliness of rescue and may lead to untimely rescue
