A kind of airborne land dummy instruction management system and management method thereof
Technical field
This technology relates to autoflight system category, is specifically related to utilize voice recognition technology, realizes robotization land dummy instruction discrimination capabilities, realizes robotization application of instruction management function, reduces the method and apparatus of cockpit crew's labour intensity and operating mistake.
Background technology
The present age, the automatic flight function of aircraft was realized by the synergy of flight management system, flight control system and autothrottle system.Wherein, by keyboard or knob, the initial work of aerial mission is carried out to flight management system by cockpit crew, flight management system is according to the input of aircrew, such as weather, course line, highly, the data such as speed and fuel oil, calculate and optimize aerial mission, generating the Flight Plan Through Intermediate Stops from takeoff and anding, and the dependent instruction of this flight planning is supplied to flight control system operating aircraft, there is provided individual to autothrottle system steering maneuver device, realize robotization flight thus.
Cockpit crew has the instruction of three major types aerial mission usually.One is the aerial mission of airline schedules center dispatch; Two is traffic administration instructions that air traffic control personnel assign in flight course; Three is that the operation that cockpit crew makes according to actual conditions such as weather determines.
The approach that cockpit crew obtains instruction has three kinds.One be air traffic control department reply flight planning and written instructions; Two is the e-command and the character instruction that utilize plane radio to set up the air-ground data communication chain reception and registration between the sky of land; Three is the Speech Communication by plane radio, i.e. voice commands.
Under prior art level and appointed condition, Speech Communication is ground and cockpit crew's means of communication the most easily, is secondly the character information of air-ground data communication chain.Therefore, the division of labor of existing communication mode is, Speech Communication transmit flight safety directly related at once, the important or instruction that needs the other side directly to respond; Other modes such as papery or air-ground data communication chain communication mode, for transmitting the directly related information of non-flight safety, such as flight planning, navigational intelligence and airline's operation demand.
Due to the defect of wireless communication technology self, such as easily disturbed by other equipment, even Changes in weather, call personnel accent, ability to express are uneven, especially L proficiency, in addition the air traffic pressure that contemporary airport is more and more busier, the misinterpretation that Speech Communication causes is the key factor causing aviation accident always.
On March 27th, 1977, two frame Boeing-747 aircrafts bump against in Spain, cause two machines totally 583 passengers and crew be murdered, be airplane crash event maximum in the world up to now, immediate cause is exactly the instruction that cockpit crew has misread air traffic control personnel.
In past more than 30 year, various technology is able to general advance, but the situation that the aloft aphasis of air transportation causes airplane crash or dangerous situation to occur, does not change so far.
On July 6th, 2013, the accident before the OZ214 flight performing South Korea Seoul-san francisco, usa lands of Han Ya mono-frame Boeing 777 airplane, cause three Chinese Human-Female students to be murdered, dozens injured, aircraft is damaged.In this accident, because the instrument landing system (ILS) on airport, San Francisco is in service mode, there is no the guide of instrument glide path, namely can not automatic Landing, the manual operation of flight unit declines, and requires that land is linked up timely and effectively.The recording of cockpit voice recording instrument shows, at crucial moment, Korea S pilot cannot carry out effective English communication with San Francisco air traffic control personnel.For this reason, US Federal Aviation Administration promptly announces, foreign airline is necessary instrumentation approach procedure in San Francisco, reduces communication demand.

On September 3rd, 2013, Korean Air public relation department sends written material and claims, and the left runway 05L of control zone Xi'an, Xi'an control order was interpreted as right runway 05R by great Han crew by mistake at that time, really occurred unsafe incidents.Korean Air is admitted, censuring L and R due to left and right runway in English has certain similarity, and both sides link up and go wrong.
The operation of aircraft in landing process is the busiest and complicated, needs Speech Communication, links up and response so that quick.Simultaneously, actual traffic situation is understood for making other flight units, any cockpit crew can listen to the call of other aircrafts and air traffic control personnel by dedicated channel, check whether and the aerial mission conflict of oneself or relevant, this work is referred to as " keep and listen ".In addition, cockpit crew also needs to continue to listen to front aerodrome and air route information.These aerodrome and sail information, by the on-site public frequency broadcast in airport, are referred to as " lead to and broadcast ".
Nowadays, the air traffic of large airport, especially hub is increasing, simple and clear in the urgent need to land sky call, fast and accurately, avoids cross-question and correction, saves radio channel resources, so that the empty caller in other lands uses; Meanwhile, as the important step ensureing flight safety and flight benefit, cockpit crew must conscientiously " keep and listen " and the moment checks " lead to and broadcast " information.But the investigation statistics digital proof of international industry, only have 20% relevant to the aerial mission of the machine by keeping the flight message of listening acquisition, this is the key factor causing cockpit crew's labour intensity too high.
International Civil Aviation Organization the flying fatigue of cockpit crew and aircraft when near airports runs with other flying activities conflict that to confirm as be the hazards that contemporary air transportation is flown." keep and listen " work of aircrew and be the work load of cockpit crew and air traffic control personnel in the voice activity communication of strang country, especially when running into the conditions such as bad weather, liaison task is increased sharply.In addition, under existing traffic control system, aircraft is from ground to aerial take-off process, and from aerial to the landing mission on ground, be made up of ground control, airdrome control and air traffic control three special voice frequencys respectively, call volume is concentrated especially, and channel switch is frequent, easily causes the error of operation and language understanding.

Accompanying drawing explanation
Fig. 1: the structural representation being the present invention airborne land dummy instruction management system
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, the computer instruction form database of " the English radio land sky dialogue term manual of standards " database having International Civil Aviation Organization's regulation in standard instruction database 7 and the air traffic services that has International Civil Aviation Organization to specify, instruction logging modle 1 is for gathering the Speech Communication information coming from aeronautical radio station 2, navigational intelligence leads to the speech information broadcasting 3 and the character instruction data message coming from air-ground data communication chain 4, instruction identification module 5 passes through voice recognition technology, based on " English radio land sky dialogue term manual of standards " database, the speech of the empty personnel in land is carried out to the automatic identification of director data, such as, when speech is input as " B-2301, MU5403 flight, to climb ten thousand metres, terminate " time, identification software can identify " aircraft number of registration B-2301 ", " flight MU5403, Shanghai-Chengdu ", " ten thousand metres of climbing " these four information, be presented on flight displays, confirmed by cockpit crew.Meanwhile, according to the digitized processing after identification, also automatically this information is sent back to terrestrial air traffic administration personnel by air-ground data communication chain and confirm.
Instruction identification module 5, by character instruction recognition function, by the data acquisition of air-ground data communication chain and comparative analysis, identifies command information wherein in time.
If cockpit crew, or the instruction that terrestrial air traffic administration personnel are unconfirmed identified, these instructions process as " without confirmation ".The mark of " without confirming " realizes by color or font difference.These unidentified information only supply cockpit crew's reference.
Whether the instruction no matter automatically identified is through confirming, the command information after identification all puts into instruction storage library 6 record automatically, so that cockpit crew recalls reference at any time.
Dependent instruction identification and confirm after, the flight planning correlation parameter that flight management system is performing by land dummy instruction management system automatically associates.Such as, identify " aircraft number of registration B-2301 ", " flight MU5403; Shanghai-Chengdu ", after " ten thousand metres of climbing " these four information, instruction configuration module 8 automatically contrasts the flight planning module 9 in flight management system reason immediately, by " aircraft number of registration B-2301 ", " flight MU5403 " these two instructions, are confirmed to be the aerial mission that the machine performs; By " ten thousand metres of climbing " this instruction, instruction configuration module 10 is automatically configured in the flight planning of flight management system, namely according to the automatic input of the digitalized commands of these " ten thousand metres ", flight management system completes amendment flight planning automatically, submit to cockpit crew to check and confirm, farthest reduce the workload that cockpit crew manually inputs, reduce human error's chance thus.
Instruction comparison module 10 will realize following functions:
Auditory function is kept in robotization: by the dialog context of the empty personnel in automatically-monitored all lands, utilizes based on the relevant information with this scheduled mission, refines the dependent instruction with this schedule flight.The information that this aerial mission is correlated with refers to the sail information in the flight planning performed in flight management system, such as predetermined use course line, way point, flying speed, flying height, turning point, predetermined use spatial domain, air corridor, runway and the information such as shelter bridge of ascending the throne.
Robotization is kept auditory function and will automatically the sky call instruction of all lands be compared with these relevant informations.Once find relevant, then automatically show and be prompted to cockpit crew and note.
When cockpit crew confirms, these command informations are associated with the predetermined information of this schedule flight automatically.If cockpit crew confirms amendment, then automatically modify, operated by input through keyboard without the need to cockpit crew, raise the efficiency, greatly reduce the error of manual operation input.
Robotization error-disable function: the comparing function utilizing robotization, carries out the mistake proofing inspection of four levels.
Ground floor mistake proofing is, if cockpit crew is by keyboard or knob modify instruction, the height value of the manual amendment of such as cockpit crew is 23,800 feet; But the digitalized commands of the empty conversational speech identification in land is 32,800 feet.Namely applied by this function, identify that the instruction of flight unit people amendment and the instruction of air traffic control personnel may exist contradiction.Propose to warn for this difference, ask cockpit crew to carry out being confirmed whether input error occurs, or misinterpretation.
In the KAL9831 flight example of Korean Air on August 19 in 2013, when Korea S's unit because misread, and when taking to land to Xian Xianyang International Airport 05R runway, this device lands because speech recognition is 05L, therefore this directionality mistake will be found at once, point out at once, the surface instruction that this device identifies is 05L.
Second layer mistake proofing is, if cockpit crew makes aircraft fly to 238,000 feet by practical operation, but the instruction of the empty conversational speech identification in land is 328,000 feet, and application of instruction management devices is once to detect actual deviation excessive, propose warning information, submit to cockpit crew to check confirmation.In the KAL9831 flight example of Korean Air on August 19 in 2013, when Korea S's unit because misread, and when taking to land to Xian Xianyang International Airport 05R runway, this device such as, because can pass through the data in air-ground dialogue Data-Link, the data of ADS-B, and the aircraft flying before identifying in time to land is all land on 05L runway, therefore this directionality mistake will be found at once, pointing out at once, aircraft before this device identifies, is not all that 05R runway lands at 05L runway.
Similarly, on July 6th, 2013, in the Boeing 777 of the Han Ya OZ214 flight example when san francisco, usa lands, in default of the guide of instrument glide path, lack the protection to decline section, must manual operation decline.If there is this device, this device such as, because can pass through the data in air-ground dialogue Data-Link, the data of ADS-B, the actual decline section of the aircraft landed is flown before timely identification, can be found by contrast, the decline section of this aircraft is higher before this, then seriously on the low side.So Han Ya fly unit just have can actual can reference decline section guide, the generation of this accident can be avoided.
Third layer mistake proofing is that originally cockpit crew correctly performs instruction, but revises because of various reasons afterwards, such as, carries out provisional height change to evade front thunderstorm, then forgets the height recovering command request.According to the setting of system, after deviation reaches certain hour, application of instruction management devices reminds cockpit crew check and be confirmed whether perform original instruction.
4th layer of mistake proofing is that cockpit crew employs certain function mistakenly, causes a certain instruction to fail to be performed.At this moment, can this missing term of Timeliness coverage, reminded immediately and warned.On July 6th, 2013, the Boeing 777 of Han Ya OZ214 flight is when san francisco, usa lands, it is minimum approach speed that cockpit crew sets 137 joints, but be provided with the function of auto-throttle mistakenly, and think that auto-throttle can keep 137 joint speed, be negligent of monitoring, cause air speed too low and smash.If apply this device, this device contrasts the deviation that aircraft present speed and preset value 137 save automatically, once find that deviation transfinites, such as, in present event, auto-throttle fails response because flight unit arranges mistake, then can alarm, saves aircraft.
Subsidiary function is coordinated in robotization: when performing robotization instruction configuration application function, flight planning module can utilize the flight planning modify feature in flight management system, or self load corresponding flight planning amendment application program, budget and preview are carried out to the effect of modify instruction, cockpit crew thus can the Scientific evaluation ground traffic control management personnel requirement amendment feasibility of Current Flight Plan, rationality and security, carry out fully in time coordinating and consulting.
Such as, when above-mentioned requirements climb ten thousand metres instruction input after, this device is by the correlation function of flight management system, preview its climbing performance at once, and the characterization result that will climb is shown to cockpit crew's assessment, is conducive to coordinating feasibility and the rationality of the instruction of these ten thousand metres of climbing with terrestrial air traffic administration personnel at once.On July 6th, 2013, the Boeing 777 of Han Ya OZ214 flight is when san francisco, usa lands, because it is comparatively harsh that what San Francisco terrestrial air traffic administration personnel provided enter nearly permissive condition, cause cockpit crew's operating aircraft from higher fast on the low side partially slow, finally smash.If utilize the preview function of this device, cockpit crew identifies this risk in advance, and terrestrial air traffic administration personnel coordinate more reasonable and safer descent clearance again with San Francisco.
