Seaborne wireless communication system and communication networking method based on Beidou positioning

Abstract

The invention relates to a seaborne wireless communication system based on Beidou positioning and a communication networking method. The system comprises satcom on the move hardware platforms and a shore mobile communication base station. The satcom on the move hardware platforms are arranged on ships and the ships are link nodes. Each satcom on the move hardware platform comprises a satcom terminal antenna, a wireless terminal module, a control module, a wireless relay module, a Beidou module and a wireless local coverage module. The satcom terminal antennas for receiving surrounding base station signals establish connection with the shore mobile communication base station in an automatic search mode. The satcom terminal antennas are connected with the wireless terminal modules. The wireless terminal modules are connected with the wireless relay modules, the Beidou modules and the wireless local coverage modules through the control modules. The wireless relay modules are independently connected with relay antennas. The Beidou modules are connected with Beidou antennas. According to the system and the method, through combination of the shore mobile communication base station, a seaborne worker can realize shore and sea communication in an ad-hoc network mode.

Description

technical field [0001] The invention belongs to the technical field of maritime communication, and in particular relates to a maritime wireless communication system and a communication networking method based on Beidou positioning. Background technique [0002] Maritime communication is related to the safety, communication and supervision of marine operators, and is also conducive to the healthy and sustainable development of the marine economy. [0003] At present, there are two ways for maritime communication at home and abroad: one is satellite communication system, and the other is digital walkie-talkie communication. Satellite communication occupies a dominant position in maritime communication due to its advantages of large coverage area, large communication capacity and flexible maneuvering, and is also the focus of current maritime communication applications. However, the high cost of satellite communication is the main difficulty in its promotion. Maritime telephon...

AI Technical Summary

Problems solved by technology

Digital walkie-talkies can only perform point-to-point or point-to-multipoint maritime voice communication, and cannot access the public network, and cannot realize free shore-sea communication

[0004] According to the 3GPP agreement, the furthest coverage distance of mobile communication is 110 kilometers. Beyond this distance, due to delay, the signaling channel and data channel will interfere. Even if the signal can be received, the data cannot be parsed for communication.
