Description
Technical field
The utility model relates to AIS (Automatic Identification System) technology, particularly based on the navigation mark terminal of ship automatic identification system.
Background technology
Navigation mark is the important aids to navigation of boats and ships in the channel safe navigation.The major function of navigation mark is direction, boundary and the obstruction that indicates the navigation channel, discloses relevant navigation channel information, for safe, economic navigation channel is pointed out in ship's navigation.Traditional navigation mark, its fundamental mode are to provide various navaid information by aids to navigation and navigational lighting aid to passing ships, and the navaid information of transmission has nothing in common with each other between difference in functionality and different types of navigation mark.
The navigation mark sign transmits different navaid information with signs that can see, difformity, different colours, different legends by day.Navigation mark light then is with the light of different colours with different flash the navigation indication that rule (being called the characteristic of a navigation light) provides, as green (green light does not flash) calmly when darkness or light are dark, fixed red (red light, do not flash), Morse signal " A " flash of light (short is long), or the like.Traditional navigation light with the light and shade of photosensitive component detection daylight with the startup of decision light constantly.The navigation light that need flash disposes flashing control circuit, characteristic of a navigation light flash of light on request.For prolonging the life-span and the maintenance period of navigation light, dispose " changing the bubble machine " usually and more change the bulb, take turns to operate.Newer navigation light then uses light emitting diode, and the life-span is longer, and power consumption economizes.
In the project that is called " navigation mark remote control telemetering system " of beginning, people begin to transform traditional navigation mark with " navigation mark controller " before and after domestic 2000.Because navigation mark is implemented can save the manpower and financial resources cost that navigation mark is patrolled greatly behind the remote measuring and controlling, improves the Compensation Liability for Damage Caused by the Fault in the Administration of Aids to Navigation effect, thereby is subjected to the welcome of Compensation Liability for Damage Caused by the Fault in the Administration of Aids to Navigation department.
On the reforming mode, some navigation mark controllers still utilize the glittering of original flashing control circuit control bulb by interface (as the SPI serial line interface), and controller itself lays particular emphasis on the communication function that adds remote measuring and controlling.It is prerequisite that this kind reforming mode provides communication interface and communications protocol with former navigation mark control circuit.
Other navigation mark controller then replaces original control circuit, directly controls the startup of bulb and flashes.Because navigation light is of a great variety, the control mode of requirement also can be different, and the design of control hardware interface is difficult to accomplish extensive adaptation.The only interface mode of certain class navigation mark often needs to determine through Field Research.
The latest development trend is that navigation mark producer directly adds the remote measuring and controlling function in the design of navigation light, for the user provides incorporate remote-control romote-sensing type navigation mark.Like this, independently the application of navigation light controller will be only limited to the transformation at the old navigation mark of labour.
The communication task of realizing remote measuring and controlling has AIS system mode and GPRS/CDMA1X public network mode.The contrast of dual mode sees Table 1.

The workflow and the principle of this routine navigation mark terminal are as follows:
After the navigation mark starting up of terminal, mourned in silence earlier one minute, adopt FATDMA or RATDMA to insert the AIS network then, at first launch the navigation mark message No. 21.
Next just enter the utonomous working stage.In this stage, the navigation mark terminal that has networked should adopt the FATDMA/RATDMA access mode to distribute oneself transmission time slot and emission, up to shutdown.
When the navigation mark terminal was in accepting state, radio-frequency module 11 was changed to transmit-receive switch " reception " state, and the information on the VDL data chainning connects 10 by the VHF antenna and takes down, and sends into receiver.After received signal process front-end clipping, filtering, low noise amplification, the image frequency filtering, be mixed to an intermediate frequency down; After an intermediate-frequency section carries out filtering, processing and amplifying, mixing and enter two intermediate frequency demodulation parts once more; Two intermediate frequencies carried out filtering and amplification to the signal after the mixing before using the orthogonal coherent demodulation, be coupled out one road signal simultaneously and be used for RSSI (the intensity indication of received signal).After radio-frequency module 11 sends the signal that demodulates to baseband module 12, carry out NRZI (Non return to zero again, inverted) decoding and HDLC (High level DataLink Control) data unpack processing, parse message content, and determine mode of operation, report rate, message format to be launched and content, candidate transmitting time slot etc. according to these content of message.
The navigation mark terminal is before selected transmission time slot arrives, 12 pairs of armed message of baseband module are carried out HDLC packing and nrzi encoding, when transmission time slot arrives, export data to be launched to radio-frequency module 11 transmitters, simultaneously " PTT " (Push-to-Talk) signal be changed to effectively; Radio-frequency module 11 is changed to transmit-receive switch 13 " emission " state immediately, and transmitter is started working simultaneously; Radiating circuit carries out GMSK (Gaussian-filtered minimum shift keying) modulation to data, involve power amplification after filtration again after, go out by VHF antenna emission 10; It is invalid that baseband module 12 is changed to " PTT " signal at the end of transmission time slot, and to turn-off the radio-frequency module transmitter, radio-frequency module is changed to transmit-receive switch " reception " state simultaneously, makes it enter accepting state once more.
Energy supply control module 15 is controlled the charging of solar panels to accumulator automatically according to the running parameter that injects in advance, and gathers solar panels, accumulator, navigation light working current, magnitude of voltage and state, sends to baseband module 12 by data port; Behind 12 groups of bags of baseband module, by the base station of VDL link with the information transmission; When the equipment of detecting broke down, energy supply control module 15 sent to malfunction baseband module 12 immediately, and packing data modulation back is sent to the base station by wireless mode with warning information.
