Transmission instruction is closed, by Beidou satellite communication unit, all ships are sent with the request of positioning and time service, ship gets request
Afterwards, it returns and works as prelocalization, the time of Beidou satellite communication unit record return information, the time required to calculating transmission, then will " when
The instruction of preceding time+transmission one-way time " is gone over, boat-carrying gateway acquisition instruction, and is updated to the time.
The existing satellite communication of integrated utilization of the present invention, short wave communication and mobile communication, realize multi-channel parallel broadcaster
Under formula, the high fault-tolerant networks of warning information single-shot, group hair and the whole network mass-sending are supported.
When carrying out information exchange with bank base, Intelligent routing selection is carried out to bank base information and transmission, data packet can be by each
The transmission rate of channel is weighted and averaged calculating, obtains the transmission ratio of each channel in the unit time, by all data packets
Proportionally conveyed toward corresponding each channel.
As shown in Fig. 2, being applied to boat-carrying gateway communication of the present invention the present invention also provides boat-carrying gateway communication method
System, including boat-carrying gateway and communication unit, communication unit includes Beidou satellite communication unit, four signal communication unit of wind and cloud, short
Wave communication unit, telecommunication satellite communication unit, mobile comm unit, short-range wireless communication unit, terminal device on ship, it is described
Beidou satellite communication unit, four signal communication unit of wind and cloud, short wave communication unit, telecommunication satellite communication unit, mobile comm unit,
Terminal device is connect with boat-carrying gateway in short-range wireless communication unit, ship.
Boat-carrying gateway communication method of the invention includes the following steps:
S1: monitoring all communication channels, to be received and stored by communication unit to information；Information is for example
For warning information, ID coding is then the ID of warning information, each warning information carries a unique ID coding, compares ID
Coding helps to judge whether boat-carrying gateway is successfully received all data packets of warning information, if finished receiving,
Then abandon the data packet of the identical ID coding received below.
S2: the information received is decoded and is calculated corresponding information fragment；
S3: judging information fragment identical with currently decoding, the information fragment calculated whether has been stored in memory, if
Have, then abandon the information fragment being currently received, otherwise, the current information fragment for decoding, calculating is stored；
Each warning information can be divided into several information fragments.After boat-carrying gateway receives data packet, by decoding and calculating
After obtaining each information fragment.The information fragment is obtained if having passed through decoding in storage and having calculated, abandons the fragment.And lead to simultaneously
Cross the quantity of monitoring information fragment, if it is consistent with original fragment sum, to judge whether block sort collects completely.
S4: ID identical in the memory information fragment encoded is recombinated with preset order；
S5: the information after recombination is sent in terminal and is shown.
In S1 step, whether the information fragment received also according to ID coding judgement is stored in memory, if so,
The information fragment is then abandoned, otherwise, stores the information fragment.
Between S3 step and S4 step further include: judge that the same ID in memory encodes the sum of corresponding information fragment
Whether amount is consistent with raw information fragment quantity, if so, executing S5 step, otherwise, returns to S1 step.
In S2, the information fragment has fragment serial number；In reconstitution steps, by the information point of ID identical in memory coding
Piece is recombinated with putting in order for fragment serial number.
With reference to Fig. 3, before information transmission, the information for needing to transmit can first be divided into several isometric information point
Piece is labeled with serial number for each piece, and the fragment serial number of the serial number i.e. information fragment can be denoted as the first ordered series of numbers { an }.So
Two neighboring block sort is subjected to differential encoding afterwards, each by former and later two block sorts is done the operation of inclusive OR, obtained
Fragment to after other column coding, and label is denoted as the second ordered series of numbers { bn }.Purpose is that two neighboring information fragment is allowed to generate pass
The information fragment of loss still can be restored back to by system if being lost one of information fragment by calculating.Encapsulation
When, three coded slices are selected from { bn } at random, point of the position " 3k+1 " is in addition randomly selected from prime information fragment { an }
Piece is incidentally upper to be used as redundancy.The position of selection 3k+1 is just can be also to meet three coded slices above, in addition in quantity
Position is separated by not far, can substantially reduce the probability of failure.Two neighboring information fragment { an }, can pass through the calculus of differences of inclusive OR
Afterwards, another set information fragment { bn }, fragment data i.e. information fragment in figure are obtained.With reference to Fig. 4, such as it is lost
A group information fragment in { bn } still can be restored all information fragments { an } by other two direction.Number in figure
According to fragment i.e. information fragment.
Gateway of the invention receives broadcast data, is handled, screened and is distributed.Intelligent routing is carried out to bank base information
Selection and transmission provide the wire/radio network communication service based on TCPIP to information in ship.When boat-carrying gateway receive it is all
After fragment, can by all information fragments by USB interface on ship or short-term apart from cordless communication network, information fragment
It is all distributed in terminal, information is restored in order by terminal.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection scope of the claims in the present invention
Within.
