Protocol conversion submodule is designed with corresponding geocoding, is equipped with for the data after parsing in each protocol conversion submodule
Information performs syntax conversion unit, semantic conversion unit and the sequential of syntax conversion, semantic conversion and timing conversion respectively
Converting unit；
In step 2：Central controller parses the communication protocol type of data message to be forwarded and sender and recipient
Between protocol conversion relation after, according to the protocol conversion relation between sender and the communication protocol type of recipient, to treat
One-to-one addressing is encoded therewith for the data message generation of forwarding；The addressing coding represents same protocol conversion for matching
The geocoding of relation；
In step 3：Communication Protocol Conversion submodule is encoded according to addressing coding come match address, so as to be the data letter after parsing
Breath match protocol transform subblock；Syntax conversion unit, semantic conversion unit and timing conversion in protocol conversion submodule
Unit carries out syntax conversion, semantic conversion and timing conversion to the data message after parsing respectively.
9. the data forwarding method of the multi-function communication device for analogue system under water according to claim 8, it is special
Levy and be：The interrupt module includes interrupting allows deposit unit and interrupt priority level deposit unit；The interruption allows deposit
Unit is used to be turned on and off the permission to interrupt requests, and the temporary data message for being allowed for including interrupt requests；Institute
State interrupt priority level deposit unit for read interrupt permission deposit unit in the data message for including interrupt requests and sentence
Disconnected its priority, and it is ranked up and kept in from high priority to low priority；
Interruption feedback module, Read-write Catrol module and data compressing module, the read-write are additionally provided with the central controller
Control module is used for the number that is sent in controller of primary data information that will include interrupt requests according to the order of priority
According to parsing module, or the final state data message of interrupt requests will be included it is sent to data compressing module；The Read-write Catrol
Module is used to be sent to interruption feedback module the completion instruction for representing that read-write is completed；The interruption feedback module is used to complete to refer to
Order feeds back to interrupt priority level deposit unit；
In step 1：First deposit unit is allowed to open the permission to interrupt requests by interruption, then receiving interface data transmit-receive module
The primary data information for including interrupt requests for sending, and the temporary initial number for being allowed for including interrupt requests it is believed that
Breath；Read by interrupt priority level deposit unit again and interrupt the primary data information for including interrupt requests allowed in deposit unit
And judge its priority, and it is ranked up and kept in from high priority to low priority, it is then high according to priority
Low order is sequentially transmitted to Read-write Catrol module, then parses mould to the data in central controller by Read-write Catrol module forwards
Block；Read-write Catrol module often completes once to forward just complete to interrupt priority level deposit unit transmission one by interrupting feedback module
Into instruction, interrupt priority level deposit unit receives the primary data information deletion for completing that forwarding will have just been completed after instructing, and makes
Next primary data information to be forwarded becomes limit priority；
In step 3：Interrupt allow deposit unit receive and keep in communication Protocol Conversion submodule send include interrupt requests
Final state data message；Afterwards, then by interrupt priority level deposit unit reading interruption permission deposit unit interruption is included
The primary data information and final state data message of request simultaneously judge its priority, and it is entered from high priority to low priority
Row sequence is simultaneously kept in, and is then sequentially transmitted to Read-write Catrol module according to priority sequence, then by Read-write Catrol mould
Block is transmitted to data compressing module or data resolution module in central controller；Read-write Catrol module often completes once to forward
A completion instruction just is sent to interrupt priority level deposit unit by interrupting feedback module, interrupt priority level deposit unit is received
To primary data information or final state the data message deletion for completing will just to have completed after instruction forwarding, make next to be forwarded initial
Data message or final state data message become limit priority；
In step 4：Final state data message is compressed into after packet data compressing module the communication protocol being sent to recipient
Corresponding interface data transceiver module, then corresponding communication interface is sent to by interface data transceiver module is forwarded.
