Embodiment

For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

The data communication that the adjacent air traffic control task interval in AIDC (ATS Inter-facility Data Communications, data communication between traffic control facility in civil aviation) to be International Civil Aviation Organization the be Asian-Pacific area is formulated and the standard agreement that control electronics is transferred.Establish the handling process between two air traffic control automation systems based on AIDC agreement, the adjacent air traffic control task interval in the Asian-Pacific area carries out control transfer according to this handling process.

Before setting forth the handling process between two air traffic control automation systems set up based on AIDC agreement, first introduce several noun.ATSU (Air Traffic Services Units, air traffic services unit), Controlling ATSU, hereinafter referred to as C-A, can be understood as air-traffic control mission transfer side; Receiving ATSU, hereinafter referred to as R-A, can be understood as air-traffic control mission reciever, namely C-A initiatively contacts R-A, for transferring air-traffic control mission to R-A.International Civil Aviation Organization (International Civil Aviation Organization, ICAO) normal process that AIDC control is transferred is defined, according to ICAO standard, in AIDC control hand-over, relate to 8 stages, 12 kinds of type of messages, C-A or R-A can only receive the message of corresponding kind in each stage, and other messages are considered as misrepresenting deliberately without exception.12 kinds of messages comprise: ABI (ADVANCE BOUNDARY INFORMATION) reports, MAC (COORDINATION CANCELLATION) reports, CPL (CURRENT FLIGHT PLAN) reports, ACP (ACCEPTANCE) reports, CDN (COORDINATION) reports, EST (COORDINATION ESTIMATE) reports, PAC (PREACTIVATION) reports, REJ (REJECTION) reports, TOC (TRANSFER OF CONTROL) reports, AOC (ASSUMPTION OF CONTROL) reports, LAM (LOGICAL ACKNOWLEDGEMENT MESSAGE) reports, LRM (LOGICAL REJECTION MESSAGE) reports.

The handling process transferred based on AIDC control between two air traffic control automation systems that AIDC agreement is set up is as follows:

C-A sends ABI report, and notice R-A has airborne vehicle (comprising the aircraft that aircraft, dirigible, balloon etc. fly in atmosphere) will enter its regulatory area, and C-A can receive the message of R-A feedback within a certain period of time.In the process of the message of C-A wait-receiving mode R-A feedback, C-A can send MAC and report cancellation notice.After sending ABI report, C-A has two kinds of selections, wherein a kind of selection sends CPL report to R-A to hold consultation, if R-A agrees to the content in CPL report, then send ACP form and show acceptance, as fruitless agreement then send CDN report modify, after this both sides can mutually send CDN report hold consultation, until wherein one side send ACP report then coordinate terminate.Alternatively send EST report or PAC report to R-A, now R-A can only reply the acceptance of ACP report, and other any message is invalid packet, after C-A receives ACP report, coordinates to terminate.C-A is when sending message, if airborne vehicle takes off, then it sends EST report, if airborne vehicle not yet takes off, sends PAC report.Send difference that CPL report report with EST and be that the other side can modify to the content during CPL reports and again consult, and EST is reported and can only be accepted.If now either party also will modify to handover condition, CDN report can be sent again and coordinate, until wherein a side sends the acceptance of ACP report or sends the refusal amendment of REJ report and terminate.As cancelled coordination, then C-A sends MAC report, and turning-over operation need start anew again.After coordination terminates, C-A sends TOC report, and R-A replys AOC report, then transfer successfully.If C-A does not receive the AOC report that R-A replys at the appointed time, then need C-A again to send TOC report and carry out turning-over operation.

Set up in AIDC control hand-over at C-A and R-A, enter the next stage after receiving the LAM report of the other side's response at the appointed time, proceed AIDC control and transfer.If can not receive LAM report or receive LRM report, be retracted on last stage; Can not receive corresponding message at the appointed time, also will be retracted on last stage.Such as, send EST report, have received LAM report, but confiscate ACP report at the appointed time, then return the stage sent before EST report.In hand-over, have received MAC report, then return the initial period.

In AIDC control hand-over, only receive in setting-up time, identify the AIDC message that method, system is sent, and reply corresponding AIDC report could carry out AIDC control transfer smoothly, because the understanding of different manufacturers to AIDC there are differences, cause when carrying out AIDC control and transferring, there is the AIDC message that two mutual nonrecognition of ATC system send method, system, and then corresponding reply can not be provided, cause AIDC control to transfer unsuccessfully.

The flow process of interconnected conversion method is transferred in Fig. 1 control shown between a kind of air traffic control automation system that the embodiment of the present invention provides.Consult Fig. 1, interconnected conversion method is transferred in the control between a kind of air traffic control automation system that the embodiment of the present invention provides, and interconnected conversion equipment is transferred in the control be applied between air traffic control automation system, and the method can comprise step:

Step S101: the message that interconnected conversion equipment reception sender ATC system sends is transferred in the control between air traffic control automation system, and unpacks the decomposition of laggard row format to the message received, and obtains the message information of this message.

Step S102: the AIDC message format obtaining recipient's ATC system according to the destination address in this message information, and be the AIDC message format of recipient's ATC system of this AIDC message by the format conversion of the message of this reception, obtain the AIDC message after format conversion.

Destination address can be recipient airport title, the ATC system that each airport adopts is known, the AIDC message format that each ATC system adopts is known, the AIDC message format that the ATC system that airport title and its can be adopted, this ATC system adopt is associated and shows, according to this contingency table, as long as of obtaining in contingency table can know associated with it other.That is to say, recipient's ATC system of this message can be obtained according to destination address, obtain the AIDC message format of recipient's ATC system.

AIDC message is made up of following 12 parts altogether on form: group, text first symbol, message text, the end of text character, telegram end when header, station serial number, time of receipt, destination address, telegram message precedence, time of transmission, address of transmitting messages, day.May difference be there is in different ATC system to the form of AIDC message.Such as:

(1) algorithm of CRC (Cyclic Redundancy Check, cyclic redundancy check (CRC)) check code and initial value arrange difference.CRC check code has hundreds of algorithm, and the CRC code that different algorithms calculates is certainly different; The initial value of CRC can be set to any one integer between 0-65535, and the CRC code that different initial values has obtained after having carried out shifting function also can be different.

(2) difference of header and telegram end: header can be set to ZCZC or 0x01; Telegram end can be set to NNNN or 0x03.And space between header and station serial number, can be had also can there is no space.

(3) text first symbol is different from the end of text character.With common AFTN (Aeronautical Fixed Telecommunication Network, AFTN) message that transmits is different, AIDC message can add text first symbol and the end of text character at the head and the tail of message text, owing to being option, so different ATC system is also different in configuration, both may have, also may both not have, also likely only have text first symbol or only have the end of text character.

(4) during day, group is lack of standardization.In the distinctive marshalling the inside of AIDC message, one has 2,3,4,5 these four marshallings, and wherein 2,4,5 marshallings are essential options, but the LAM of TELEPHONICS (one of air traffic control automation system) system report does not have the 2nd to organize into groups.Give the correct time at reply ACP, some ATC system can add that the 3rd organizes into groups, and some ATC system does not add, and causes stylistic disunity.

In the control hand-over of AIDC, the wherein side in two ATC system is after sending AIDC message, and only after the corresponding message receiving the other side's reply, AIDC control is transferred and just can be entered the next stage.Recipient's ATC system will reply corresponding AIDC message, first the AIDC message that can identify reception is then needed, according to the form of the AIDC message of this reception, the AIDC message of replying corresponding format just can the side's of being issued ATC system identify, and then triggering AIDC control transfer proceeds.

In the method that the embodiment of the present invention provides, the AIDC message that interconnected conversion equipment reception sender ATC system sends is transferred in control between air traffic control automation system, form decomposition is carried out to the AIDC message received, judges that header is ZCZC or 0x01, telegram end is NNNN or 0x03, whether with the addition of text first symbol, text before text after whether with the addition of the end of text character, the initial value that carries out CRC check is how many, day time group in the condition that whether has the 3rd to organize into groups etc.; Then obtain destination address, address of transmitting messages, the time of receipt, the information such as time of transmission; Last according to destination address information, obtain the AIDC message format of recipient's ATC system, according to the AIDC message format of recipient's ATC system, be the form of the AIDC message of recipient's ATC system by the format conversion of the message of reception, obtain the AIDC message after format conversion.

Step S103: be transmitted to recipient's ATC system by after the AIDC message package after format conversion.

Only have and the format conversion of the message of reception is identified by AIDC message format that recipient's ATC system can identify could be received square ATC system, and then provide and reply message accordingly.Also only have and detailed analysis has been carried out to the message received, the characteristic of this sender's ATC system on AIDC message format could be understood, the corresponding AIDC message that recipient's ATC system is replied could be converted to the AIDC message format that sender's ATC system can identify, and then just can the side's of being issued ATC system identify, to enter next AIDC control handoff procedure.

In the method that the embodiment of the present invention provides, control between air traffic control automation system transfers interconnected conversion equipment as intermediate conversion side, format analysis is carried out to the AIDC message received, according to the destination address in AIDC message information, the AIDC message format that the format conversion of the AIDC message this received can identify for recipient's ATC system, will carry out the AIDC message repeating after format conversion to recipient's ATC system.In the method that the embodiment of the present invention provides, transfer interconnected conversion equipment by the control between air traffic control automation system and format conversion is carried out to the AIDC message that AIDC control transfer both sides send or receive, make both sides can carry out control transfer smoothly, simplify handoff procedure, improve and transfer efficiency and fail safe.

Different ATC system except having except difference on AIDC message format, and the AIDC interface provided also may be different, and the host-host protocol of employing also may be different, although xenogenesis ATC system AIDC interface can be connected, the difficulty that is directly connected will be quite large.The flow process of interconnected conversion method is transferred in Fig. 2 control shown between another air traffic control automation system that the embodiment of the present invention provides.Consult Fig. 2, as another kind preferably execution mode, interconnected conversion method is transferred in the control between another air traffic control automation system that the embodiment of the present invention provides, and can comprise step:

Step S201: the message that interconnected conversion equipment reception sender ATC system sends is transferred in the control between air traffic control automation system, and the laggard row format decomposition of process is unpacked to the message received, obtain message information.

Step S205: obtain the AIDC message format that recipient ATC system adopts according to the destination address in message information, and be the AIDC message format of recipient's ATC system by the format conversion of the AIDC message of this reception.

Step S206: the host-host protocol obtaining the employing of recipient's ATC system according to the destination address in message information, carries out package again by carrying out the transformat of the AIDC message after format conversion according to the host-host protocol of recipient's ATC system.

Step S207: by the AIDC message repeating of package again to recipient's ATC system.

Control between air traffic control automation system is transferred interconnected conversion equipment and is provided multiple external interface, the AIDC message that all ATC system send can be received, the transformat of the host-host protocol of this AIDC message of transmission can be identified according to the interface receiving this AIDC message.

Destination address can be recipient airport title, the ATC system that each airport adopts is known, the AIDC message format that each ATC system adopts is known, the AIDC interface that each ATC system provides, the host-host protocol of employing are known, the host-host protocol that the AIDC message format that the ATC system that airport title and its can be adopted, this ATC system adopt, this ATC system adopt is associated and shows, according to this contingency table, as long as of obtaining in contingency table can know associated with it other.That is to say recipient's ATC system that can obtain this AIDC message according to destination address, obtain the AIDC message format of recipient's ATC system, obtain the transformat of the host-host protocol of recipient's ATC system.

AIDC message transmissions generally adopts following several agreement: HDLC, X.25, asynchronous serial port, ICP/IP protocol.

HDLC (High Level Data Link Control, high-level data link control procedure) agreement is one of most widely used agreement in the communications field, it is bit-oriented high-level data link control procedure, has the feature of powerful, the efficient and synchronous transmission of error detection occurs.In HDLC communication mode, all information is all the HDLC agreement regulation transmitted in the form of frames, and all information transmission must start with a banner word, and terminate with same banner word.The information unit that between opening flag word to end mark word, formation one is complete, is called a frame.Recipient can find out beginning and the end of frame by search end mark, set up frame synchronization with this.The unloaded phase between frames, can banner word be sent continuously fill.

IP to provide in Internet data unit transmission end to end by adopting connectionless service.Agreement is the most basic agreement of Internet, briefly, is made up of the IP agreement of bottom and Transmission Control Protocol.Network IP agreement provides the flexibility that can adapt to various network hardware, bottom-layer network hardware is almost had no requirement, as long as any one network can transmit binary data from the three unities to another place, IP agreement just can be used to add Internet.

When RS232 is individual equipment access computer, the normal a kind of access way adopted is asynchronous communications protocol, and its hardware implementing is simple, therefore has in traditional equipment and much have employed this communication mode.

X.25 the point-to-point interoperability between normalized definition DTE and DCE, DTE (i.e. user's X.25 DTE terminal) connects dce device (base band MODEM, switch etc.), usually, cisco router is DTE side, by V.35 or RS232 cable be connected with DCE (base band MODEM).X.25 the telephone network of data communication is defined.First a side calls out the opposing party by request interprocess communication before communicating, and called party accepts or refuses this calling.If call setup, two systems can start to carry out full-duplex data transmission, either party can at any time in connection breaking.X.25 agreement is a kind of agreement that CCITT (ITU) advises, its definition terminal and computer are to the connection of packet switching network.

Control between air traffic control automation system is transferred interconnected conversion equipment and is provided multiple external interface, adopts different hardware implementing to operate the transmission of different agreement, such as employing synchronous communication card transmission HDLC and X.25 agreement; RS232 asynchronous communication is realized with serial port board; TCP/IP communication is realized with 100M Ethernet card.When the startup of interconnected conversion equipment is transferred in control between air traffic control automation system, hardware and interface that configuration file carrys out the use of initialization needs can be read, set the transmission rate of each interface.After receiving AIDC message, the transformat of agreement according to the interface receiving this AIDC message carries out de-packaging operation, and then the transformat of the host-host protocol changed on demand re-starts package operation, realizes transport protocol conversion.

In the method that the embodiment of the present invention provides, control between air traffic control automation system transfers interconnected conversion equipment by carrying out transport protocol conversion, the AIDC message that sender's ATC system is sent can be adopted by another ATC system of differing transmission protocols receive, realize AIDC control between two different ATC system and transfer.

Control between air traffic control automation system transfers interconnected conversion equipment when forwarding AIDC message, and all messages to receiving may not be needed all to forward to recipient's ATC system.Such as, when using AFTN net transmission AIDC telegram, the inside may be mingled with common AFTN telegram, now can select all to carry out forwarding or only forward AIDC telegram wherein.For another example, if sender's ATC system send be format error AIDC report, then also can not need to be forwarded.As preferably execution mode, the control between the air traffic control automation system that the embodiment of the present invention provides is transferred in interconnected conversion method, also comprises before step S205:

Step S202: can message information be obtained after form decomposition is carried out to the message received, according to message information, the message received be resolved.Judge that whether the message of this reception is the correct AIDC message of form, if not then directly filtering, namely format conversion do not carried out to this message and forward.Continue to receive the message that sends of described sender's air traffic control automation system, and judge that whether the message of described reception is the correct AIDC message of form, until receive the correct AIDC message of form according to the message information of received message.

Now, according to the destination address comprised in described message information described in step S205, data communication AIDC message format between traffic control facility in the civil aviation of acquisition recipient air traffic control automation system, comprise: the destination address comprised in the message information according to the correct AIDC message of described form, to obtain in the civil aviation of recipient's air traffic control automation system data communication AIDC message format between traffic control facility.
