Technical field

It is more particularly to a kind of to be filled based on event driven Data-Link uplink triggering the invention belongs to aerospace applications engineering technology Put, further relate to the triggering method based on event driven Data-Link uplink triggering device, be mainly used in AOC fields.

Background technology

Civil aviaton's Air-ground data link (calling in the following text " Data-Link ") is that one kind uses ATN (aeronautical telecommunication network) wireless network communication technique And application protocol, the system for realizing data information exchange between aviation aircraft and terrestrial information management system.It passes through VHF (very high frequency(VHF) communication), SATCOM (maritime affairs/iridium satellite satellite communication), HF (high frequency communications), SSR (secondary surveillance radar) S mode As Data-Link transmission medium, information is transmitted automatically between aircraft and ground system, by the personnel and blank pipe on aircraft and ground certainly The effective connection of dynamicization system together, can effectively reduce flight operating cost, improve flight operational efficiency, find flight event in advance Barrier, ensure flight safety.Especially, in China, with the fast development of aviation transport, civil aviaton's message volume increases Add, but at present, the Yun Kong departments of airline are still mainly realized between flight unit by the speech communication link of blank pipe Voice communication.Because the defects of voice communication channel is crowded, interference from human factor becomes increasingly conspicuous, and establish the behaviour of uplink communication Make complexity, often set up the bottleneck of vertical active voice communication with flying machine as Yun Kong departments, maintenance control department, directly affect Flight safety and flight are on schedule.In the last few years, air-ground data communication system was because its transmission rate is fast, strong antijamming capability, error code The features such as rate is low, reliability is high, workable is widely applied in civil aviaton's air-ground dialogue field.

ACARS (Aircraft Communication Addressing and Reporting System)-aircraft leads to Letter addressing and reporting system, it is the link of a ripe vacant lot real-time digital communication, data is undertaken by data-service providers Communicate infrastructure and paid data retransmission service.At present, the main application fields that ACARS systems have extended include AOC with ATC, the former be mainly directed towards airline can autonomous control application field, acquisition such as aircraft-position information, flight information letter The acquisition of breath and push, the automatic acquisition of biography, aircraft engine state and aeroplane performance parameter, the unit down of flight failure information Developable autonomous application of short message two-way communication and other airlines etc.；The latter is mainly directed towards air traffic control and public affairs Many service fields, digitlization of such as taking off is let pass (Departure Clearance), foreign border digitlization clearance (Oceanic Clearance), aviation terminal information service (ATIS), automatic dependent surveillance (ADS), controller and Driver data's chain control (CPDLC) etc..

ACARS systems are mainly made up of airborne equipment system, air-ground data communication network and ground application system.It is airborne to set Standby system with communication management component (CMU) (or identical functions component) for core component, including flight management system (FMS), in Entreat maintenance system (CMCS), Aircraft Condition Monitor System (ACMS), S mode answering machine, high frequency (HF)/very high frequency(VHF) (VHF)/satellite Communication system (SATCOM), airborne printer and unit display system (MCDU) etc.；In air-ground data communication network, ATN nets Network is formed with SITA, ARINC Liang great independent datas supplier (DSP), is amounted to more than 10 individual data operators as main body, is covered Cover the aeronautical telecommunication network including south poles region (using HF mechanicss of communication, dtr signal) or even global every nook and cranny； In the ground application system of AOC application fields, airline uses the data link gateway access device that DSP is provided and ATN networks Docking, the flying quality of this airline is obtained in real time, it is integrated interactive with aircraft bidirectional information by background application.

But ACARS and its communication technology mainly solve be flying quality and ground system real-time, interactive problem, and For AOC ground application systems, it does not provide the side of " actively sending uplink triggering instruction according to aircraft downlink information " Method, at present, ground staff can only be interim to carry out artificial data analysis according to the descending information of aircraft, reuse corresponding software Instrument sends up-on command to target aircraft, and such way has operational hysteresis quality, artificial mistake/error, omission Etc. drawback, the randomness, real-time and accuracy of job requirements can not be ensured.

In addition, in AOC aircraft maintenance application system, it is generally the case that ground system is also required to according under aircraft Row information actively sends uplink triggering instruction, to obtain more flight parameters, judges the instant system mode of aircraft with this, To be accurately positioned the failure of aircraft.

The content of the invention

First purpose of the present invention be to provide it is a kind of in real time, be accurately based on event driven Data-Link uplink triggering Device, uplink triggering instruction is actively sent according to the downlink information of aircraft, to obtain more flight parameters, judges to fly with this The instant system mode of machine, so as to be accurately positioned the failure of aircraft, to ensure that flight safety creates active condition.

First purpose of the present invention is realized by following technical measures：One kind is based on event driven Data-Link Row trigger device, it is embedded in decoder of the AOC ground application systems for decoding downlink message, and is entered in decoder master Cheng Zhong, it is characterised in that：It is described to be included based on event driven Data-Link uplink triggering device：

Effective number inspection module of aircraft, for checking effective aircraft number；

Constraint database module, for compiling constraint database；

Masterplate definition module, for predefining uplink triggering command template；

Up-on command generation module, refer to for target aircraft number to be implanted into uplink triggering command template generation uplink triggering Order, and cached into up message buffering pond, i.e., uplink triggering instruction is pushed into airline data chain gateway interface, Again uplink triggering instruction is sent from airline data chain gateway interface to target aircraft；

Effective number of the aircraft checks that module, the constraint database module and the up-on command generation module connect successively Connect, the masterplate definition module is connected with the up-on command generation module；Effective number of the aircraft checks that module receives target The decoded information of aircraft downlink message is as conditional parameter, if the conditional parameter is effective, the target aircraft is effective aircraft Number, and decoded information is exported to constraint database module, if the conditional parameter is invalid, the target aircraft flies to be invalid Machine number, and return to decoder host process；Constraint database module compiles constraint database, if constraint database is to decoded letter Unrestraint is ceased, then performs uplink triggering instruction, if constraint database has suppression to decoded information, does not perform uplink triggering Instruction, and return to decoder host process；The masterplate definition module predefines uplink triggering command template, the up-on command life Target aircraft number is implanted into the generation uplink triggering instruction of uplink triggering command template into module, otherwise (such as because IO, network are different Often, it is impossible to generate uplink triggering instruction), decoder host process is returned to, the uplink triggering instruction of generation is cached to uplink message In buffer pool, i.e., uplink triggering instruction is pushed into airline data chain gateway interface, then by airline data chain gateway Interface sends uplink triggering instruction to target aircraft.

It is of the invention artificial data analysis to be carried out temporarily, then make according to the descending information of aircraft with existing ground staff The way that up-on command is sent to target aircraft with corresponding Software tool is compared, and has randomness, the reality for ensureing job requirements The advantages of Shi Xingyu accuracys, it is up can to realize that AOC ground application systems can actively be sent according to the descending ACARS information of aircraft Triggering command, to obtain more flight parameters, the instant system mode of aircraft is judged with this, to be accurately positioned aircraft Failure；The present invention can also trigger the data needed for aircraft generation (transmission), or produce corresponding driving cabin warning, be met with this Ground surface works system obtains more aircraft real-time status parameter requirements under case of emergency, or alerts the potential emergency rating of unit Occur, to ensure that flight safety creates active condition.

Uplink triggering of the present invention instructs reports frequency, descending according to aircraft for dynamically changing aircraft-position information Failure code or failure keyword triggering ACMS (Aircraft Condition Monitor System) status information it is descending, according to aircraft it is descending therefore Barrier code or failure keyword triggering aircraft EICAS (engine indicates and unit warning system) safeguard page number information it is descending, Triggering airborne information system structure parameters are descending or according to the descending ACMS flight overloads of aircraft automatically in flight course Parameter up unit warning message automatically.

Each downlink message is encapsulated as object structure by decoder host process of the present invention turns into downlink message object, institute Stating downlink message object includes message ID, message time stamp, aircraft number, flight number and message content this 5 attribute.The condition Parameter is decoding table name (i.e. ACARS event names) and downlink message object.

Effective number of aircraft of the present invention checks that module is used as two conditions to decode table name with downlink message object first Parameter is checked, if one of conditional parameter is invalid, it is invalid to return, and returns to decoder host process；If two conditions Parameter is effective, to decode table name with the aircraft number attribute of downlink message object as two input parameters, is pointed to masterplate and determines EDUT configuration lists in adopted module are done using EDUT-ID as the one-to-one connection associated with effective aircraft number inventory, obtain one Result set, if the number of entries in the result set is more than 0, then it represents that a certain in the triggerable EDUT configuration lists of the target aircraft number The EDUT configurations of definition, then return effectively, i.e., the target aircraft is effective aircraft number；Otherwise, then it is invalid to return, i.e., the target flies Machine is invalid aircraft number.

EDUT configuration lists and two configuration lists that effective aircraft number inventory is backstage of the present invention, are that system manager makes With the two kinds of back-end datas generated after the man-machine interface configuration system shown in Fig. 8, Fig. 9.The generation of up-on command generation module is up Both back-end datas can be called during triggering command.

EDUT configuration lists：Trigger condition (the EDUT determined is mainly formed by masterplate, constraint database and effective aircraft number Configuration), the set of multiple trigger conditions forms EDUT configuration lists, and each trigger condition has unique number, i.e. EDUT-ID.

Effective aircraft number is for EDUT configuration lists, and each entry in inventory has one group of effective aircraft number (multi-aircraft), target aircraft number are the aircraft numbers that uplink triggering instruction finally determines, i.e. instruction will issue which airplane, target Aircraft number must be in effective aircraft number list.

Constraint database module of the present invention is to decode the message ID attributes and aircraft number category of table name, downlink message object Property input condition as its compilation process, the aircraft number attribute to decode table name and downlink message object is used as two inputs to join Number, does using EDUT-ID as the one-to-one connection associated with effective aircraft number inventory to EDUT configuration lists, obtains a result Collection, every record circulation in the result set is performed, if the constraint database that EDUT is configured in EDUT configuration lists is to current Downlink message object unrestraint, then allow to perform uplink triggering instruction, the constraint database module is by downlink message object Message ID attributes, timestamp attribute, aircraft number attribute, flight number attribute and decoding table name be sent into up-on command generation module； Conversely, not performing uplink triggering instruction then, decoder host process is returned.

Each downlink message is understood to a unique object, i.e. downlink message object.In high-level [computer In, it is a kind of conventional technical method that aleatory variable, which is encapsulated as " object ",.Each ACARS messages have many different category Property, these attributes encapsulations together, form the entirety that can be re-used, be exactly described downlink message object (if It is uplink message, can also equally does this objectification processing).The downlink message object is in decoder downlink message monitor process It is middle by disposable objectification, use is repeated as many times as required in host process.If not objectification, each host process accesses the descending report Text just needs an I/O operation, certainly will consume substantial amounts of I/O resource in a large amount of downlink message processing procedures, institute after objectification Some I/O operations are converted to internal memory operation, while IO expenses are greatly lowered, be greatly improved system processing speed with Efficiency.

Downlink message object is by " message ID " or RAW_ID determine that RAW_ID is the unique identification to downlink message.Solution Each downlink message is unique in code device, and decoder downlink message monitor process can distribute one only to each message automatically One identification number, i.e. RAW_ID, it is made up of a 9 bit length positive integers, i.e., maximum is 999999999.According to current statistics, The airline of 500 airplanes, about 200000 ACARS downlink messages, are calculated, RAW_ID reaches maximum with this daily Take around 13 years.That is " life cycle " of system is about 10 years, the beginning of next life cycle, RAW_ID will since 1, with This circulation.

The trigger event that masterplate definition module of the present invention includes being sequentially connected defines submodule, definition change type Module, masterplate editor submodule, masterplate inventory submodule and uplink triggering start and stop submodule, the trigger event define submodule For defining trigger event (as decoding table name, determine that masterplate is relevant with which kind of event), the trigger event is decoder Start the event that uplink triggering instruction is sent when receiving certain types of downlink message；The definition change type submodule is determined 4 kinds of change types of justice, the message ultimately produced for one one new message generated in real time by aircraft of triggering, triggering aircraft, One one current boat being stored on airborne non-volatile memory apparatus of message and triggering by unit/manually ultimately produce of triggering The bulletin of section；The masterplate editor submodule provide the basic coding form of uplink triggering instruction, embedded ATN networks command character with And uplink triggering instruction reserved word or macro substitution symbol；The masterplate inventory submodule is used for system manager and operates completion triggering thing The binding of part, change type and masterplate, and uplink triggering start and stop logic is set, while effective aircraft number is bound, set database Constraint；And the operable revision uplink triggering instruction of system manager, to realize that finer uplink triggering instructs configuration；It is described Uplink triggering start and stop submodule starts for event, i.e., up touch just is performed when decoder receives current flight nth event Send instructions transmission；When N is 0, this condition is bypassed；When decoder is to the maximum times of current flight transmission uplink triggering instruction When 0, this condition is bypassed.

All uplink triggering instructions must be predefined, and this is considered based on following two reasons：

(1) the generating process of uplink triggering instruction is complicated, is manually entered process and easily produces mistake, causes up failure；

(2) also possible input error instruction is manually entered, leads to not trigger required downlink information.

The masterplate of uplink triggering instruction is pre-defined on backstage by having qualified system manager, and front end applications pass through choosing Select suitable masterplate and send correct up-on command, avoid above-mentioned two from easily producing wrong link with this.

Masterplate definition module can work out different masterplates according to the response parameter specification of different type airborne equipment, will be airborne Equipment response parameter is embedded, or downlink message of the trigger packet containing different parameters is sent, or changes the existing ACARS messages of aircraft Logic is sent, or causes the driving chamber effect of different-effect (such as driving cabin clock rings warning, or driving cabin emergency warning lamp is bright, or is driving Sail and show text prompt information on cabin display (MCDU), or content of text is exported in cabin printers), to remind unit The generation of potential danger, so as to unit make it is preventative evade, for ensure flight safety create active condition.

Effective number of aircraft checks that module, constraint database module and up-on command generation module are sequentially connected, masterplate definition Outside module is independently of EDUT processes of the present invention, completed by administrator intervention, masterplate definition module and up-on command generation module It is connected；Effective number of aircraft checks that module receives the decoded information of target aircraft downlink message as conditional parameter, if the condition Parameter is effective, then the target aircraft is effective aircraft number, and decoded information is exported to constraint database module, if this Part invalid parameters, then the target aircraft is invalid aircraft number, and returns to decoder host process；Constraint database module compiles data Storehouse constrains, if constraint database performs uplink triggering instruction, if constraint database is to decoding to decoded information unrestraint Information afterwards has suppression, then does not perform uplink triggering instruction, and return to decoder host process；Masterplate definition module predefines up Target aircraft number is implanted into uplink triggering command template generation uplink triggering and referred to by triggering command masterplate, up-on command generation module Order, otherwise, decoder host process is returned to, the uplink triggering instruction of generation is cached in uplink message buffer pool, i.e., will be up Triggering command pushes to airline data chain gateway interface, then is sent from airline data chain gateway interface to target aircraft Uplink triggering instructs.

Uplink triggering instructs and reports frequency for dynamically changing aircraft-position information, according to the descending failure code of aircraft or Failure keyword triggering ACMS (Aircraft Condition Monitor System) status information it is descending, according to aircraft descending failure code or failure Keyword triggering aircraft EICAS (engine indicates and unit warning system) safeguard page number information it is descending, in flight course from Dynamic triggering airborne information system structure parameters are descending, or according to the descending ACMS flight overload parameters of aircraft, it is automatic on Row unit warning message.

Decoder host process scans the downlink message pond being pushed to by ACARS gateways on decoder server incessantly, Period, each downlink message is encapsulated as object structure by host process includes message as downlink message object, downlink message object ID, message time stamp, aircraft number, flight number and message content this 5 attribute.

The output decoding table name (i.e. ACARS event names) after ACARS packet parsing subprocess.Conditional parameter is decoding table name With downlink message object, decoding table name checks module with downlink message object as two effective number of conditional parameter input aircrafts, Enter EDUT subprocess.

As shown in Fig. 2 in EDUT subprocess, order is completed to check effective aircraft number, compiles constraint database, starts The tasks such as the main trigger process of EDUT, if one mission failure of any of which, EDUT subprocess auto-returned decoder host processes, Otherwise, into the main trigger process of EDUT.

As shown in figure 3, effective number of aircraft checks that module is used as two conditional parameters to decode table name with message object first Checked, if one of conditional parameter is invalid, it is invalid to return, and returns to decoder host process；If two conditional parameters Effectively, to decode table name with the aircraft number attribute of message object as two input parameters, it is pointed in masterplate definition module EDUT configuration lists done with effective aircraft number inventory using EDUT-ID as the one-to-one connection associated, obtain a result set, if Number of entries in the result set is more than 0, then it represents that a certain definition in the triggerable EDUT configuration lists of the target aircraft number EDUT is configured, then is returned effectively, i.e., the target aircraft is effective aircraft number；Otherwise, it is invalid to return, i.e., the target aircraft is invalid Aircraft number.

As shown in figure 4, constraint database module is to decode the message ID attributes and aircraft number category of table name, downlink message object Property input condition as its compilation process, the aircraft number attribute to decode table name and downlink message object is used as two inputs to join Number, does using EDUT-ID as the one-to-one connection associated with effective aircraft number inventory to EDUT configuration lists, obtains a result Collection, every record circulation in the result set is performed, if the constraint database that EDUT is configured in EDUT configuration lists is to current Downlink message object unrestraint, then allow to perform uplink triggering instruction, constraint database module is by the report of downlink message object Literary ID attributes, timestamp attribute, aircraft number attribute, flight number attribute and decoding table name are sent into up-on command generation module；Conversely, Do not perform uplink triggering instruction then, return to decoder host process.

Each EDUT configurations have been likely to constraint database, the contents of each ACARS messages be it is unique, therefore, Decoder (foreground) receives any one ACARS message must all carry out dynamic analysis to its constraint database, and parsing is tied Fruit is stored in database, and starts the main trigger process of EDUT as one of input condition.

Every record circulation in result set is performed：It is in order to adapt to the polymorphism of ACARS downlink messages, i.e., each ACARS downlink messages may all trigger multiple uplink triggering instructions, and introducing has unique constraint condition (RAW_ID, i.e. message ID Number) constraint database macro substitution operation.

(1) message ID macro substitutions are carried out to the EDU_DBPARMCONST_CPL fields of every record in result set, will { RAW_ID } replaces with message ID parameter value.

(2) the EDU_DBPARMCONST_CPL field contents after macro substitution are stored in database.

(3) the EDU_DBPARMCONST_CPL field contents after macro substitution are sent into database to perform.

(4) the result EDU_DBPARMCONST_VLU after execution is stored in database.

Finally, following constraint database example table is formed：

(table 1)

Wherein, EDU_DBPARMCONST_VLU>=1, represent that the EDUT configures the database in (being determined by EDU_ID) about Beam to the ACARS messages of current downlink (by " and message ID " or RAW_ID are determined) unrestraint, that is, allow to perform EDUT uplink triggerings； Otherwise, suppress, do not perform EDUT uplink triggerings.

As shown in Fig. 5~10, the trigger event that masterplate definition module includes being sequentially connected defines submodule, definition change class Type submodule, masterplate editor submodule, masterplate inventory submodule and uplink triggering start and stop submodule, trigger event define submodule For defining trigger event, trigger event is to start uplink triggering instruction hair when decoder receives certain types of downlink message The event sent；Definition change type submodule defines 4 kinds of change types, for one new report generated in real time by aircraft of triggering One message that one text, triggering aircraft ultimately produce, triggering one preservation of message and triggering by unit/manually ultimately produce The bulletin of current leg on airborne non-volatile memory apparatus；Masterplate editor submodule provides the basis volume of uplink triggering instruction Code form, embedded ATN networks command character and uplink triggering instruction reserved word or macro substitution symbol；Masterplate inventory submodule is used for The keeper that unites operates the binding for completing trigger event, change type and masterplate, and sets uplink triggering start and stop logic, binds simultaneously Effective aircraft number, sets constraint database, and the operable revision uplink triggering instruction of simultaneity factor keeper is finer to realize Uplink triggering instruction configuration；Uplink triggering start and stop submodule starts for event, i.e., when decoder receives current flight n-th thing Uplink triggering instruction is just performed during part to send；When N is 0, this condition is bypassed；When decoder sends uplink triggering to current flight When the maximum times of instruction are 0, this condition is bypassed.

As shown in figure 5, the specific work process that trigger event defines submodule is as follows：

Trigger event (EDUT Event) refers to that startup EDUT is up when decoder receives certain types of ACARS messages The event that triggering command is sent, such as：Sent when decoder receives descending airplane fault message uplink triggering instruction triggers certain ACMS messages it is descending；Receive aircraft it is descending take off message when trigger uplink triggering instruction obtain bleed air system EICAS safeguard Page message downlink；It is descending that uplink triggering instruction acquisition motor oil state message is sent when receiving aircraft downstream position message Deng.

Because the aircraft type that different airlines are in charge of is different, there is also difference, the species of ACARS messages for electronic equipment May be different from structure, therefore the decoding capability of its individual demand and decoder is also different.Therefore, the present invention is right EDUT Event definition is open, is not bound all downlink messages of aircraft and uplink triggering instruction, but A kind of general configuration interface is provided, independently completes to match somebody with somebody according to the demand of itself or the decoding capability of decoder by actual user Put.The sample that part EDUT Event are defined is provided below：

(table 2)

As shown in fig. 6, the specific work process of definition change type submodule is as follows：

The generation or change (Modify) of one ACARS message, generation in mobile system by a variety of conditional decisions, EDUT sends different instructions and obtains the message generated under different condition.Invention defines following 4 kinds of conditions, referred to as EDUT Modifier (change type).

(table 3)

As shown in FIG. 7 and 8, the specific work process of masterplate editor submodule and masterplate inventory submodule is as follows：

EDUT masterplates provide the basic coding form of uplink triggering instruction, embed ATN networks command character and other are necessary Up-on command reserved word or macro substitution symbol, including：

(table 4)

It is similar with EDUT Event (trigger event) definition, the present invention not by all downlink messages of aircraft with it is up Triggering command is bound, and there is provided a kind of general configuration interface, by demand of the actual user according to itself or decoding The decoding capability of device is independently completed to configure.

One given below complete EDUT masterplates sample and its explanation：

(table 5)

Defined part EDUT masterplates given below and its explanation：

(table 6)

The specific work process of uplink triggering start and stop submodule is as follows, as shown in Figure 8 a, in figure, Event Start Offset represents that decoder receives current flight EDUT Event nth events and just performs up-on command transmission；It is other when N is 0 Lead to this condition；Maximum Uplinks are represented when the maximum times that decoder sends uplink triggering instruction to current flight are 0 When, bypass this condition.

Illustrate：

During Event Start Offset=1, Maximum Uplink=1, when decoder receives first EDUT Start to send up-on command during Event, this flight is at most sent once.

As shown in figure 9, the effectively determination of aircraft number：It is not that each uplink triggering instruction configuration is suitable for all aircrafts, Therefore, each uplink triggering instruction has effective aircraft on probation.The present invention provides and is directed to each effective aircraft of up-on command Number separate configurations method.

As shown in Figure 10, the determination of constraint database：Each EDUT Event may have different parameter attributes, often The position report event of individual aircraft may have different flight number, different height, different speed, airborne Fuel Remained, pre- Up to the moment, constraint database be in order to distinguish same EDUT Event different parameters, it is upper during to send different scenes Row instruction.The present invention provides quadratic programming interface, and system manager can edit the SQL words and expressions of complexity herein, to identify EDUT Parameter Conditions in Event.

Such as：

SELECT DECODE(FLIGHTNO,NULL,0,DECODE(FLIGHTNO,'CZ0303',1,0))

FROM AOC_A83POS_B787WHERE RAW_ID={ RAW_ID }

I.e.：When B787 aircraft positions report the flight number in (AOC_A83POS_B787) event effective, and it is equal to CZ0303 When, perform the transmission of uplink triggering instruction.

Wherein：RAW_ID={ RAW_ID } words and expressions represents the current location report that position report receives for decoder.To be necessary Reserved word.If lacking this reserved word, system provides warning with error configurations.

The detailed process of uplink triggering instruction generation is as follows：

As shown in figure 11, the generation of EDUT up-on commands, backstage is present in the form of system service.The descending number of aircraft Relayed to airline data chain gateway by data, services business (DSP) according to by downlink, connected safely by corporate intranet The file push system connect is sent in the downlink message buffer pool in decoding server.Decoder master control in decoding server Servo programe (Decoder) interacts according to the attribute of downlink message with the setup parameter in database server, generates on EDUT Row instruction, is buffered in uplink message buffer pool, then pushed away by the file of corporate intranet secure connection in the form of uplink message Send system to be sent to airline data chain gateway, with ATN network interfaces, target aircraft is gone upward to by DSP.

As shown in figure 12, up-on command generation module includes effective number binding submodule of aircraft, the daily record dimension being sequentially connected Shield submodule and example state safeguard submodule, and effective number binding submodule of aircraft is used to be assigned every uplink triggering instruction Imitate aircraft number；Daily record safeguards that submodule is used for the implementing result for recording every uplink triggering instruction；Example state safeguards submodule For the trigger process for safeguarding the instruction of every uplink triggering and current triggering state.

Interface decoder drives the main trigger process of EDUT：The process is serially completed by two subprocess, (i) interface decoder Primary control program input parameter is generated to EDUT up-on commands, primary control program is completed to effective number of aircraft, constraint database condition Check, i.e., up validity check, the process is realized inside decoder by interface module.Validity check fails, then exits, Otherwise, into (ii) EDUT daily records maintenance process.

Descending ACARS messages are encapsulated as comprising message ID, message time stamp, aircraft number, boat by interface decoder program The object of the attributes such as class number, message content is together sent into EDUT up-on commands as downlink message object, while by decoding table name Generate primary control program.It is identical with event name to decode table name, a descending ACARS message generates (either automatic raw aboard Into or it is manually generated) by a certain particular flight event trigger；Decoder successfully parses to an ACARS message, after parsing Data be stored in database table, this means that the event establishment in systems for triggering the message.

EDUT daily records are the database tables with aircraft number and the entitled unique constraint condition of decoding table, and its record system is up to be touched The target aircraft number that sends instructions, flight number, start to trigger descending ACARS messages decoding table name, the message of the instruction of this uplink triggering The transmission times and currently trigger the descending ACARS messages ID that this uplink triggering instructs that ID, timestamp, uplink triggering instruct (its timestamp can be obtained by anti-decoding data storehouse of looking into).

In EDUT daily record maintenance processes, if the log recording of given aircraft number and decoding table name is not present, in daily record It is middle to create new log recording, and bind above-mentioned attribute；If in the presence of updating above-mentioned attribute, while mark current triggering shape State mark (being the EDUT events being repeatedly executed in the EDUT events or current flight performed first on current flight).Newly Trigger (1) log recording after the trigger (2) of establishment or renewal starts EDUT example states as input condition to be safeguarded Journey.

As shown in figure 13, EDUT example states maintenance process safeguards machine (calling Example maintenance machine in the following text) by EDUT example states Program is realized.Example maintenance machine records to every that meets this message condition in EDUT configuration lists, performs：According to current triggering Status indicator (mark provides whether EDUT configurations allow to be performed a plurality of times on same flight) judges, if holding first OK, then the transmission of uplink triggering instruction is directly performed；Otherwise, the up thresholding of systems inspection suppresses logic, if up be not suppressed, Then flip-flop number+1 after the transmission of execution uplink triggering instruction, does not otherwise perform the transmission of uplink triggering instruction.

Up thresholding suppresses：Up thresholding suppresses logic and considers to meet following condition：

(1) up start and stop logical check

The descending ACARS event counters (p_EVT_COUNT) of current flight have to be larger than the biasing equal to default Number+1 (i.e. i_EVENT_STARTOFFSET+1, as i_EVENT_STARTOFFSET=0, no biasing limitation), i.e., system is received It is only possible to send uplink triggering instruction after to i-th _ EVENT_STARTOFFSET ACARS message.

(2) upper limit number inspection is triggered

If the uplink triggering of executed has now reached the maximum triggering times (i_MAX_UPLINK) of default, it is System stops the triggering to current flight.

(3) constraint database inspection

Constraint database checking process return parameters ii_EDU_DBPARMCONST_VLU have to be larger than equal to 1, and system is Uplink triggering instruction may be sent.

When three above condition simultaneous is logical truth, system performs uplink triggering instruction and sent, i.e.,：

(table 7)

Otherwise, system returns to following error message to system manager：

(table 8)

Update EDUT Instances Pools：

EDUT Instances Pools form (EDU_INSTANCE tables and EDU_INSTANCE_HIS tables) by two systems table, wherein:

(1) EDU_INSTANCE tables preserve same in the EDUT configuration lists by the triggering of current ACARS downlink messages event Name event instance, the current ACARS downlink messages event that its mark goes out triggers the concrete condition of a certain bar EDUT configurations, wherein wrapping Include:

(1.1) descending ACARS event names (or decoding table name) (EVENT)；

(1.2) uplink triggering target aircraft number (ACNO), flight number (FLIGHTNO), timestamp (TIMESTAMP)；

(1.3) up start and stop thresholding；

(1.4) up-on command masterplate and its text；

(1.5) constraint database condition；

(1.6) and the every time result that is performed of the configuration.

Parameter in EDUT Instances Pools determines to perform the judged result that up-on command transmission is current triggering state mark.

(2) EDU_INSTANCE_HIS records EDU_INSTANCE historical data, each descending ACARS event updates During EDU_INSTANCE, the record in EDU_INSTANCE_HIS is safeguarded that system manager can be in EDU_INSTANCE_ automatically The state that each up-on command is performed is obtained in HIS.

Perform the transmission of uplink triggering instruction：As shown in Figure 14~17, up-on command generation module also includes being sequentially connected Masterplate reading submodule, masterplate analyzing sub-module and up-on command output sub-module, masterplate reading submodule be used for read Uplink triggering command template in EDUT exemplary configurations；Masterplate analyzing sub-module is used to parse uplink triggering command template, generates Complete uplink triggering instruction；Up-on command output sub-module instructs uplink triggering in write-in uplink message buffer pool, i.e., defeated Go out uplink triggering to instruct to airline data chain gateway interface.

Masterplate reading submodule reads the uplink triggering command template in EDUT configuration lists, masterplate analyzing sub-module first The parsing of uplink triggering command template is completed, generates complete uplink triggering instruction, and cached by up-on command output sub-module Into uplink message buffer pool, that is, be pushed to airline data chain gateway interface, from gateway interface complete uplink message to The transmission of target aircraft.

Wherein, the process of masterplate analyzing sub-module parsing up-on command masterplate is as follows：

As shown in figure 15, local ATN node address (Local ATN Address) is distributed：Local ATN node address be by The seven T-shaped mothers distributed when ATN data operator (DSP) is with airline data chain gateway interface device installation and deployment Address code, shaped like CANXMCZ, DDLXCXA etc..For each data link gateway interface arrangement, the address code is unique.This In invention, ATN node address is stored in system background as system configuration parameter, parses automatic by system during up-on command Read in.

As shown in figure 16, distributively-ground (TypeB) transmits priority code：

The transmission of ACARS messages is made up of two processes：Sky transmit to ground transmission (Air-Ground transmission) and ground to ground (- ground Transmission, it then follows TypeB (ATA/IATA standards) coding criterion), at present, according to ARINC620 basic agreements [ARINC620 3.2.1], TypeB identifies being transmitted with queue priority for message using two word code QU.In the present invention, QU is with backstage The form of configuration parameter preserves, and keeper can change, by automatically reading during system analysis up-on command.But at present, ARINC620TypeB message formats only support QU.

Distribute up target aircraft number：Up target aircraft number is passed to by client application, and system is by masterplate< TARGET_ACNO>Or { ACNO } reserved word replaces with incoming aircraft number.

Distribute upstream time stamp：According to ARINC620 consensus standards, uplink triggering instruction must carry timestamp information, In the present invention, timestamp uses UTC time corresponding to the server system time (time-division point during form DDHHMM-everyday).Time Stamp is embedded in uplink message head<MSG_TIMESTAMP>.

Obtain ATN routing node states：ATN routing nodes be one follow the renewal of aircraft descending ACARS messages dynamic and The table safeguarded automatically by system, wherein including four key messages relevant with ATN network insertions：Aircraft number (ACNO), flight Number (FLIGHTNO), DSP (DSP_ADDRESS) and downgoing time stamp (DL_TIMESTAMP), routing node state table, such as Under：

(table 9)

According to ARINC620 consensus standards, different DSP_ADDRESS represent last ACARS downlink message of aircraft by Which data supplier (DSP) is provided, and uplink message must also be undertaken by the DSP, and upstream time stamp (MSG_TIMESTAMP) (DL_TIMESTAMP) must not be stabbed earlier than last downgoing time, because system can not predict aircraft in possibility of next moment DSP_ADDRESS.Meanwhile if state for extended periods of the airplane in ATN routing node state tables does not update (such as：DL_ TIMESTAMP keeps constant for a long time), then it is for a long time or out of touch with ACARS networks to mean that aircraft has stopped field.In order to prevent Expired instruction it is up, this time slot is defined as silent time slot (being represented with variable i i_MSG_Delay) in the present invention, when silent Gap is a variable that can configure in management staff.

Different DSP are not necessarily identical to the value of silent time slot, in addition the DSP having to silent time slot without any constraint.This In invention, ii_MSG_Delay should be less than the minimum value min_MSG_Delay of the silent time slots of all DSP.But in actual motion, Min_MSG_Delay is often difficult to know, and is difficult to ensure that server time MSG_TIMESTAMP and UTC strict conformances, because This, ii_MSG_Delay can use a very big numerical value under normal circumstances.

As shown in figure 17, in this case, if MSG_TIMESTAMP-DL_TIMESTAMP is silent more than certain DSP Time slot, DSP will return to message too old information to uplink message sender automatically.

In the present invention, if conditions above is unsatisfactory for：

MSG_TIMESTAMP-DL_TIMESTAMP is more than ii_MSG_Delay or MSG_TIMESTAMP-DL_ TIMESTAMP is less than 0, the miscue information that system will provide, and refuses to send uplink triggering instruction：

Downlinked message is too old,message expired over then<ii_MSG_Delay) >min,System rejected to Create the EDU for<ACNO>

Where CurrentTimeSpam=<ii_CurrentTimeSpam>

UplinkTimeStamp=<MSG_TIMESTAMP>

TimeSpamDelay=<MSG_TIMESTAMP-DL_TIMESTAMP>min

Wherein：

(1) ii_CurrentTimeSpam represents the current timestamp (UTC time) of system between MSG_TIMESTAMP Time slot, by internal system be delayed produce；

(2) angle brackets "<>" in parameter be system-computed variable

Generate complete uplink triggering instruction：It is all in uplink triggering command template after conditions above all meets Macro substitution symbol will be replaced with argument, such as：
