Description
Technical field
The present invention relates to communication equipment for ship technical field, specially a kind of AIS relay equipment peculiar to vessel and increasing Cheng Fangfa.
Background technique
There are ship automatic identification system (AIS), existing AIS with the most similar prior art of technical solution of the present invention
Equipment at least has the following deficiencies:
1, the limitation of communication distance.By the curvature of the power of antenna, the height of antenna and the earth in existing AIS equipment
It influencing, the communication distance of existing AIS equipment is 15km, however, with the promotion of shipping demand waterborne in recent years, the quantity of ship
It sharply increases, deposits the case where actual range between vessels is more than the communication distance of existing AIS equipment, cause relatively far apart
Normal communication can not be carried out between ship.Therefore, it is impossible to meet the communication contexts of safety for existing AIS equipment；
2, the limitation of communication modes.Existing AIS equipment is by very high frequency(VHF), and referred to as " VHF ", channel is broadcasted to neighbouring ship
Shipping information, with the continuous promotion of data communication needs waterborne in recent years, AIS equipment is in VHF band communication demand
Increase cause AIS equipment can be used frequency range in become very crowded, especially some busy harbours and narrow water (such as
Inland river or the navigation channel Gang Qu) the problems such as having had already appeared information occlusion, the efficiency of AIS equipment communication has been seriously affected, has been caused often
There is the phenomenon that broadcast delays can not even be sent；
3, the applicability in water areas of harbor or narrow water is not high.Since the information sender formula of existing AIS equipment is
It is carried out by VHF channel, i.e., all ships in same waters can carry out this ship information to neighbouring ship in synchronization
Broadcast, can thus occur the ship in some water areas of harbor and narrow water (such as Yangtze River waterway, the inland river Zhe Bei network of rivers navigation channel)
In the case that oceangoing ship is intensive, there is thickly dotted " flocking together " phenomenon in the ship information shown in every AIS equipment, leads to this ship ship
Member can not accurately identify required neighbouring shipping information at all, it is even more impossible to judge current security situation, so that AIS equipment
Become " chicken ribs ", many ships then occur and turn off AIS equipment privately, to reduce the energy consumption of ship and cut operating costs；
4, since every AIS equipment needs to carry out communication broadcast by high-power VHF antenna, and need to guarantee its broadcast away from
From 15km is reached, therefore, China's regulation, ship should configure 12A or more regulated power supply (while also needing one emergency power supply of configuration)
To guarantee the normal work of AIS equipment, so, for some navigation in inland river or the spitkit of reservoir, due to certainly
The limitation (itself ship electricity is more short of) of figure part is equipped with AIS equipment with regard to relatively difficult, to limit AIS equipment small-sized
Application in ship navaid and supervision and management；Further, since the problem of power consumption, also increase the construction and operation of AIS base station
Cost, which also limits the further genralrlizations of AIS.
