Description

A kind of marine rescue beacon and rescue system

Technical field

The present invention relates to sea rescue field, particularly a kind of marine rescue beacon and rescue system.

Background technology

With developing rapidly for international and domestic shipping industry, casualty probability of happening is also being continuously increased.Sea Difficult matter therefore mostly accident, are influenceed by natural causes such as wind direction, ocean current, tides, and persons falling in water is usual Spread in disorder distribution and rapidly, can drift about per hour several nautical miles even more than ten nautical miles；Persons falling in water is in sea On, often only expose head, at most only expose body 1/3rd, even if meteorological condition is preferably, by naked eyes Observation can only also search 600-700m, and night visibility is poor, search increasingly difficult.At present, rescue sea falls The difficulty of water personnel is：On the one hand, after crewman is overboard, it will floatd under wind, stream, the synergy of wave From accident position；Another convenience, is limited by current technology of searching and rescuing, and rescue personnel cannot know drowning people's Specific orientation, can only search sea by artificial observation, infrared night vision lamp method, inefficient.Existing city Life vest on field etc. is cried for help equipment, is usually mounted with GPS device, its high cost, is difficult to popularize, and GPS The transmission of device wireless transmission signal is by Lidar Equation is larger, effective propagation path is limited.

The content of the invention

It is a primary object of the present invention to overcome drawbacks described above of the prior art, propose a kind of low cost, rescue Help long distance of signal transmission, improve the marine rescue beacon and rescue system of rescue success rate.

The present invention is adopted the following technical scheme that：

A kind of marine rescue beacon, it is characterised in that：Including the label with lanyard, also installed on the label There are emergency circuit and whistle；The emergency circuit includes the key device for sending or closing emergency order, uses In overboard overboard detection means is detected whether, for the timing automatic RF emergency letters sent with identification id Number RF emitters, the battery for providing power supply, and for according to the overboard signal that receives or emergency The microcontroller of the order control timing automatic transmission RF distress signals of RF emitters.

Preferably, water-tight device is additionally provided with the label, the emergency circuit is located in the water-tight device.

Preferably, the RF emitters send the RF distress signals of 433MHz-2.4GHz.

Preferably, the label has whistle device, can be used for drowning people and voluntarily reminds rescuer and passing ship Only note.

A kind of rescue at sea system, it is characterised in that：Including seashore base station, some boat-carrying base stations and it is some on Any the marine rescue beacon stated；The boat-carrying base station be provided with RF reception devices, big-dipper satellite positioner, Maritime affairs wireless signal dispensing device and process circuit；The process circuit and RF reception devices, maritime affairs wireless signal Dispensing device is connected with big-dipper satellite positioner, after receiving RF distress signals, obtains the identification id Affiliated ship and user, and calculate overboard distance, then start this ship rescue mechanism and to seashore base station Send related rescue information；The seashore base station is provided with RF reception devices, maritime affairs wireless signal receiver and master Controller；The master controller is connected with RF reception devices and maritime affairs wireless signal receiver, comes for receiving It is and further according to the related rescue information of different boat-carrying base stations from the related rescue information that boat-carrying base station sends Overboard position is positioned, then starts seashore rescue mechanism, or after reception RF distress signals, obtain the identification The affiliated ship of ID and user, and overboard position is positioned according to the related rescue information of different boat-carrying base stations, Then start seashore rescue mechanism.

Preferably, the related rescue information includes affiliated ship, user, overboard distance, drowning people position Confidence breath, this ship position information.

Preferably, described ship rescuing machine be made as notifying that this ship begins look for persons falling in water, is rescued.

Preferably, the seashore rescue mechanism includes notifying that nearby ship is rescued or notified sea for overboard position Prison, naval, air force start rescue.

From the above-mentioned description of this invention, compared with prior art, the present invention has the advantages that：

1st, rescue beacon of the invention, is worn on user, can send audio distress signal by whistle, Can also be triggered by key device or close automatic transmission RF distress signals, or self-timing sends RF when overboard Distress signal, low cost, be easy to popularization；

2nd, rescue beacon of the invention, its RF distress signal for sending includes identification id, belonging to recognizing Ship and user, its signal frequency are 433MHz-2.4GHz, and effective propagation path is remote, can improve and be rescued into Power；

3rd, rescue system of the invention, it passes through boat-carrying base station and receives RF distress signals, obtains identification id Affiliated ship and user, and overboard distance is calculated, general overboard positional information is estimated, then start this Ship rescues mechanism and sends related rescue information to seashore base station；Seashore base station combines the multiple boat-carryings for receiving The related rescue information of base station further determines that the positional information of drowning people, then starts seashore rescue mechanism, The rescue system can effectively position drowning people position, accelerate search and rescue process, greatly improve rescue success rate.
