Description
Technical field
The present invention relates to a kind of AIS Shipborne terminal system, particularly a kind of AIS Shipborne terminal system based on Beidou satellite navigation.
Background technology
The birth of AIS (ship automatic identification system) has remedied the deficiency of radar to ship tracking; The effect that it is brought into play aspect ensureing navigation safety and protecting the marine environment receives the approval of navigation circle; This system has been another advanced person's since marine radar is used a navigating equipment; As communication between a kind of ship and ship, ship and bank and safe collision prevention means, support to have developed radar and vessel traffic service (VTS), promoted the marine security of the lives and property and navigation safety.At present; The AIS system is the marine a kind of collision avoidance system that the VHF wave band adopts TDMA exchange of skills data that moves; This system is a receiving and transmitting signal on the marine VHF87B/88B channel at two frequencies of 161.975MHz and 162.025MHz; And data such as synthetic global position system GPS, gyro compass and autopilot, radar, electronic chart, and on display, show accommodation, dynamic dispatching information on demand.
The satellite positioning tech of AIS use the earliest mainly is a GPS of USA; GPS of USA only provides hi-Fix for U.S.'s (especially US military); To the other countries user positioning service of hanging down precision only is provided, and the U.S. can close this service (particularly in wartime) at any time.Meanwhile, Beidou satellite navigation system reaches its maturity, and can high-quality location, navigation and time service service be provided to global user.Open service is to provide free the location, test the speed and the time service service to the whole world, 10 meters of bearing accuracies, rate accuracy 0.2 meter per second, 10 nanoseconds of time service precision.Dipper system has obtained the industry widespread use in fields such as China's fishery safety, forest fire protection, water conservancy flood control, communications and transportation, securities at present.The GPS of America of comparing, there are six big advantages in the big-dipper satellite system: 1) Big Dipper positioning system and AIS on the circuit with all be compatible on the agreement; 2) it possesses location and communication function simultaneously, do not need other communication system supports, and GPS can only locate; 3) dipper system has covered China and neighboring countries and regions, and coverage is big, does not have communication blind zone, not only can be China, also can be surrounding countries services; 4) being particularly suitable for management of group user large-range monitoring and data acquisition user data transmission uses; 5) merge Big Dipper navigation positioning system and satellite enhanced system two large resources, therefore GPS also capable of using makes it to use abundanter; 6) autonomous system, safety, reliable, stable, strong security is fit to key sector and uses.At present; The positioning system of AIS ship-borne equipment adopts the GPS navigation system more; The big-dipper satellite that how to make the AIS ship-borne equipment adopt China to launch is voluntarily accurately located, and accomplish with other ships and and terrestrial base station between communication become the present problem that needs solution.
Summary of the invention
The present invention can accurately locate also a kind of AIS Shipborne terminal system based on Beidou satellite navigation of ability communication data transmission for the technical matters that exists in the solution known technology provides a kind of.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is: a kind of AIS Shipborne terminal system based on Beidou satellite navigation comprises Beidou satellite navigation system terminal receiving unit, communication receiving element, communication transmitter unit, control/protocol stack/interface unit, display terminal unit and power supply unit of voltage regulation; Wherein,
Said Beidou satellite navigation system terminal receiving unit comprises the Big Dipper antenna, Beidou satellite navigation system terminal receiver and the amplification filtering circuit that connect successively;
Said communication receiving element comprises receiver front end circuit, two TDMA receivers and a DSC receiver, and said receiver front end circuit receives the signal from antenna, transfers to said TDMA receiver and said DSC receiver after the Filtering Processing;
Said control/protocol stack/interface unit receives the signal from said amplification filtering circuit, said TDMA receiver and said DSC receiver, is sent to display terminal unit and communication transmitter unit after the processing;
Said communication transmitter unit comprises a TDMA transmitter, will transmit from the signal Processing of said control/protocol stack/interface unit and through antenna;
Said display terminal unit receives signal and demonstration from said control/protocol stack/interface unit;
Said power supply unit of voltage regulation is supplied with each cell operation voltage.
The present invention can also adopt following technical scheme:
Said communication receiving element and said communication transmitter unit common antenna switch through transmit-receive switch.
The transmit frequency band of said TDMA transmitter is a very high frequency(VHF), and frequency range is: 156.025MHz～162.025MHz.
Advantage and good effect that the present invention has are: adopt the ship automatic identification system technology, embedded big-dipper satellite receiver module is on the AIS standard base; The big-dipper satellite receiver module is substituted AIS prior GPS location as locating source; Each terminal device with oneself positional information through the Beidou satellite navigation system reception, is that 156.025MHz～162.025MHz outwards broadcasts with very high frequency(VHF) such as scope again, transmitting-receiving each other between the equipment; Let the interior terminal device of frequency point ranges know the positional information of launch terminal; And can handle, analyze and provide prompting to boats and ships message sent around receiving, can show near the boats and ships that AIS equipment is housed that go this ship intuitively, the boats and ships that possibly occur colliding are on every side carried out intelligent voice prompt through integrated navigation system; Reach the effect of safe early warning; The continuous again simultaneously dynamic and static information with this ship sends to boats and ships on every side, increases the security of ship running, satisfies international standard IEC-62287 requirement.
