Maritime emergency communication system

Abstract

The invention provides a maritime emergency communication system which is used for realizing communication in a maritime emergency state and meeting emergency communication requirements in a highly confronting environment in the emergency state. The maritime emergency communication system comprises a main communication system and a mobile access communication system. The main communication systemis composed of at least two buoys, carries a broadband reconfigurable radio frequency assembly, a communication gateway, an optical signal processor, an industrial WIFI subsystem, a short-wave communication subsystem, a Beidou navigation subsystem and a hybrid energy subsystem, and is in wireless communication with an overhead airplane and a ship platform. The mobile access communication system iscomposed of a plurality of water surface robots, carries a multi-system full duplex underwater acoustic communication machine, an underwater optical communication machine, a broadband software reconfigurable radio frequency module, a short wave communication subsystem, a Beidou navigation subsystem, an underwater acoustic communication subsystem and an underwater optical communication subsystem,communicates with an underwater battle platform through an underwater acoustic communication machine and an underwater optical communication machine, and communicates with an overhead aircraft and a ship platform in a wireless communication mode.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a marine emergency communication system. Background technique [0002] Emergency communication generally refers to the comprehensive use of various communication resources to ensure rescue, emergency assistance and necessary communication when there is a sudden natural or man-made emergency, including important holidays, important meetings and other communication needs. It is a special communication mechanism that is temporary and provided to deal with natural or man-made emergencies. For example, common emergencies in daily life include highway accidents, social assistance, counter-terrorism emergency response, medical rescue, leakage of dangerous goods, environmental hazards, and natural disasters such as typhoons, floods, and earthquakes. Existing emergency communication systems will use existing public communication networks such as fixed wired networks, cellul...

Problems solved by technology

[0003] All of the above are for emergency communications that only involve land networks in civilian scenarios. In some special scenarios, for example, for emergency communications networks at sea, a complete maritime emergency communications system has not yet been formed. Existing shore emergency communications such as rescue and anti-terrorism The function of the system is not perfect for the communication of the emergency state at sea, and it cannot meet the special needs of emergency communication in the high confrontation environment of the state of emergency
