On the other hand, the data flow between control system and flight process are single is single, promptly outputs to the print progress list from control system, sends control order by the flight controller according to analysis and judgement to the print progress list then.This streams data is not real-time, and it once transmits when flight process singles print, owing to time-delay and other reasons, same flight or batch the process single system can print many parts, this also gives identification and searches and bring bigger difficulty.
In order to alleviate controlling officer's work load, digging utilization flight process is singly carried out the potentiality of control operation and is improved flight controller's work efficiency, many researchs and discussion have singly been done to the flight process in recent ten years by many countries, attempt powerful by advanced person's electronic computer technology development function, to use easily the electronics process single fundamentally to improve the working method of flight process list, remedies the shortcoming of the existing papery flight process list of printing.The typical technical progress of this respect has United States Patent (USP) 5659475,5764508 and 6131065, though these technology attempt to solve the problem of the automation of air traffic control from different perspectives, but from actual effect, practicality is still not enough, and these technology are primarily aimed at external air traffic control rules, domestic can not directly the employing.In addition, domestic some research institute is also single in the flight process of research and development electronization, just singly is presented on the display printing the flight process but these electronic flight processes are single, and increases some as simple functions such as automatic orderings, function is limited, and operation is also inconvenient.
Except the flight process was single, the flight card also was one of important tool of using in China's air traffic control.The card that flies is the common name of using " transporter ferry flight registration card ", " redeployment of fighters flight registration card " and " interior a, card of flight registration outside the venue " in the present dayroom work of Control Centre at different levels.Control Centre at different levels mainly with the flight card grasp flight planning, the contact aircraft let and put down in writing air traffic bulletin fly away.Operation to this flight card also is important link in the control operation.But now the flight card that uses is all manually copied, and not only the card amount is big, to copy content many, takies a lot of activity durations, but also goes wrong easily.Be badly in need of realizing the electronization of flight card in the practice.
Now,, and used widely, but also this technology is not applied in the example in air traffic control field at present in fields such as computer peripheral equipment, mobile phones based on the hand-written script recognition technology of pattern-recognition comparative maturity.

Embodiment
As shown in Figure 1, air traffic control set of the present invention is made up of processor, display screen, touch-screen and electronic pen four parts on hardware is formed.Wherein processor 1 is the data storage and the processing enter of this air traffic control set, display screen is 15 inches LCDs, it is the display device of this air traffic control set, touch-screen is 15 inches capacitance touch screens, its effect is to write down the operation of controller on the single interface of flight process, carries out the foundation of business processing as processor.Display screen and touch-screen coincide, and become as a whole.Because they are used in combination and operate, appellation is convenient in order to use, and display screen and touch-screen are referred to as hand-written display screen 2.Electronic pen 3 is cooperated with touch-screen, and the pen tip position information of operating on the single interface of electronics process with the controller triggers touch-screen to form the operation person's handwriting.This air traffic control set carries out data interaction by network interface or serial port and radar monitoring seat data processor 4.
Processor is a computing machine with strong arithmetic capability.It is as the core specialized equipment of air traffic control set, and system provides powerful data processing function for the electronic flight process.On the one hand, processor need carry out such as data processing such as alarm, automatic orderings, and on the other hand, it carries out two-way data communication in real time with control system again.The hardware configuration of processor can be taken all factors into consideration each side factors such as processing power, memory capacity, communication capacity, reliability and select flexibly.
Display device in this air traffic control set adopts LCDs.It has constant light source, does not have the problem of flicker, does not also have electromagnetic radiation, and is long-term in the face of also being not easy fatigue; LCDs is complete plane, does not have the curved surface distortion of CRT display screen; It is not subjected to the interference of electromagnetic field.Simultaneously, LCDs is littler than unidimensional CRT display screen power, thermal value is low, average life is also long than CRT display screen.Therefore, it is to be fit to the display device that air traffic control set uses.
Different with existing similar products, the present invention adopts exclusive electronic pen input mode, does not use keyboard fully.This input mode had both been looked after the flight controller and had been used the custom of printing flight process list and flight card for many years, had improved the efficient and the quality of data inputs again greatly.
The advantage of traditional prints process list is the flexibility ratio height of writing on it, and what the flight controller in the above can be random writes, and write the restriction in zone hardly, but its shortcoming is data typing control system automatically.The electronic flight process that this equipment of use provides is single, and various control data also need the typing control system.Existing similar products adopt keyboard entry method mostly.This input mode is to using flight process Dan Eryan and inconvenient.On the flight process is single a lot of columns are arranged, the data layout of these columns is a lot: the combination of numeral, punctuation mark, letter, Chinese character, control symbol and these data layouts.Owing on the electronic flight process is single a lot of columns are arranged, require to carry out earlier the location of input focus during input; Because data layout is more, may need frequent carrying out to change between the various forms during input again.As seen, if use keyboard will inevitably make the excessive input operation of being absorbed in data of controller, make the control operation become complicated as input equipment.
This air traffic control set creatively adopts capacitive touch screen and electronic pen as input equipment, and the built-in handwriting input identification software that improves greatly through adaptive improvement, recognition efficiency, make the controller only need utilize electronic pen just can finish the total data input service quickly and easily.Controller's energy only need concentrate on the link of air traffic control, disperses energy on the data input element and not be used in, and is minimized with regard to the labour intensity that makes whole air traffic control work like this, and control efficient is improved.
The triggering mode of existing capacitive touch screen has two kinds: pressure activated and electronic impulse trigger.The capacitive touch screen that the present invention selects for use adopts the electronic impulse triggering mode.In this triggering mode, the induction point influence that is not stressed, the triggering of an induced electricity subpulse.Adopt can the emitting electrons pulse the electronic pen false triggering that thing just can be avoided pointing as triggering, the pressure of palm or other objects causes.These induction points of continuous sampling can obtain good handwriting, just can obtain high recognition with this person's handwriting as the input data of handwriting recognition module.In addition,, can fit together closely with display screen because this screen is a kind of extremely thin transparent membrane, the controller with electronic pen in the operation feeling on the touch-screen just as on the process of reality is single, the visual and ease for use height of operation.
On the basis of above-mentioned hardware combinations, want to realize the single and flight card of electronic flight process of the desired realization of the present invention, also will be through series of steps as shown in Figure 2.Now be described as follows:
(1) the electronic flight process of generation standard format is single on display screen.

Table 4 remarks section
In order to look after the existing use habit of controlling officer, this air traffic control set has adopted operation interface as shown in Figure 4, and set up two zones: candidate regions and electronic flight process are single to be distinguished, the candidate regions on the left side has been placed current all electronic flight processes list above corresponding to the single frame of the process on the control operator's console.The electronic flight process of this moment singly is in deflated state, the information such as location point, height and time that only comprised the aircraft sign and showed with current sorting operation.The electronic flight process of candidate regions singly is the result according to certain rule compositor.It is single that the candidate regions of single page can discharge 30 electronic flight processes, when the process list surpasses 30, can come its page turning by the page-turning button of candidate regions upper end, can realize the expansion of the single number of this district's process like this.
The zone of flight controller to the print progress single operation simulated in the single district of electronic flight process.The electronic flight process singly is in magnifying state in this district, has shown all the elements of electronic flight process list.The flight controller can singly carry out various operations to the electronic flight process.Under the situation of tiling fully, the electronic flight process singly can be placed five in this district.If to its drag and drop its part is overlapped, then can discharge 30.In this zone, the flight controller can also singly draw the electronic flight process, transmits messages, ordering and various control operation.The air traffic control personnel only need fill in data with electronic pen on capacitance touch screen, the single person's handwriting that just can automatically the air traffic control personnel be filled in of electronic flight process automatically converts corresponding electronic data to, imports and is presented on the electronic flight process list.Allow air traffic control personnel sensation just as to print the single sample of flight process ground free and relaxed filling in.
(2) utilize the hand-written script recognition technology that the person's handwriting of controller on hand-written display screen discerned.
Hand-written script recognition technology used in the present invention adopts step as shown in Figure 5, can discern the plurality of kinds of contents that comprises numeral, English alphabet, Chinese character, symbol etc., and can realize that a plurality of characters are once discerned, multirow is discerned, special stroke is discerned immediately.
Traditional hand-written script recognition methods mainly comprises: method of identification that tactic pattern method of identification, statistical pattern recognition method, statistics combine with structure and artificial neural network method of identification etc.Hand-written script identification software used in the present invention is except that adopting above-mentioned traditional method to do the pre-identification, also adopt multinomial new recognition strategy and method, particularly own distinctive feature is arranged at aspects such as leggy characteristics algorithm, Free Writing fractionation, the identification of numeral dislocation stroke, numerals even pen identification.These methods all have detailed explanation in the public technology document.This software utilizes above-mentioned new recognition strategy to provide quick secondary accurate recognition function, has solved the tradition lower problem of system recognition rate real-time to a great extent, especially vital digit recognition rate is improved greatly.
(3) data that identify are carried out the data adaptive processing.
In practice, the airport control center that has need concentrate in together type, wake flow and cruise speed, and the airport that has does not then need wake flow is listed in wherein; The airport control center that has needs very many information, and the Control Centre that has may only need low volume datas such as location point, national airport.For different Control Centre, the data layout of these data sets also is different, so can't in software is realized it be enumerated one by one.We are called the Adaptive Data collection with these data sets.It is the data set that conventional data and each airport control center are set up according to the business demand of oneself.This data set does not have unified format, does not almost have identical data.
For this situation, we have created a dictionary table in database, and this dictionary table carries out the adaptability definition for data set and the form thereof that the airport needs.The structural model that this description driving realizes provides strong support for the adaptivity of data set.The user interface of this program module as shown in Figure 6.In interface when operation,, it obtains all data sets by exchanges data agent controller and data storage and processing module from dictionary table description, and then find corresponding tables of data according to these descriptions is read the data of this table and is added in the form on right side.When upgrading database table, the identification form of handwriting recognition also depends in the dictionary table for the description of this data set, and it concerns as shown in Figure 7.
In the present invention, the interface display that provides of display screen has been divided into five parts: electronic flight process single operation interface, the single query statistic of electronic flight process interface, electronic card operation interface, electronic card query statistic interface and Adaptive Data storehouse maintenance interface.These interfaces provide powerful interactive function, and the operation that the flight controller can carry out on these interfaces is very many.On flight controller's the present interface of control operation table bigger randomness is arranged, if make the direct update system data of result data of these control operation inevitable or the robustness and the reliability of system damaged.For being very difficult for this to happen, interface module is not directly mutual with system data, carries out data access authority check and the check of data legitimacy but act on behalf of this middle layer controller by exchanges data, guarantees the safety of system data.In addition, this module not only provides the media of demonstration for system data, and it also as the agency of identification module, carries out suitable processing to identification form and recognition result, and it concerns as shown in Figure 8.
The basic structure of above-mentioned exchanges data agent controller as shown in Figure 9.It has following function:
1) data dispatch.Data processing is serial, and the operation of data is concurrent.The exchanges data controller is reasonably dispatched according to certain rule these concurrent data queues, reduces the congested of data processing, improves data processing efficiency.
2) data allocations.The flow direction of various data is different, how to make to keep the efficient and unobstructed of streams data and flow to correctly, is system high efficiency, carries out effective assurance of data processing reliably.The exchanges data controller is selected rational switching path according to data flow, carries out exchanges data at each intermodule of software.
3) data detection.The data of mistake can cause great injury to the reliability service of system.On the one hand, to carry out the mistake proofing inspection to invalid data in the designing process of programs, realize the terminal last prevention of doing.On the other hand, the exchanges data controller also filters misdata outside data processing, intercepts misdata from the source.
The exchanges data agent controller has been arranged, and is not random with free by above-mentioned user interface to the visit of system data.Because flight controller's operation is random relatively, mistake and redundant data also may appear in the service data.Therefore user interface will be subjected to the examination and the check of controller to the visit of system data.User interface is submitted the visit application according to the operating right of oneself to controller, and controller is according to the access rights of user interface each several part and the content of visit application, for it provides data access service.For read-only visit application, controller can extract data apace and in time these data be returned to user interface.For the visit application that requires the update system data, controller can at first be checked the access rights of mentioning application, checks the legitimacy of these data then.If legal data then are updated to it in system data timely, and the chain change of other data that will cause owing to the change of these data is also upgraded timely.
After the Data Update success, system data is finished all renewal operations with the timely notification controller of content that needs in all user interfaces to upgrade by the controller guided user interface.
This user interface has been isolated system data and its operation and demonstration to the visit of the system data mode by controller mandate and agency, the system data disorder of having avoided user's faulty operation to cause.
(4) system receives the data after adaptive processing, operates according to the instruction of data representative.
The system data processing module of this air traffic control set software systems is being undertaken various Processing tasks such as data preservation, alarming processing, ordering processing, for data presentation and database storing provide Data Source.In order to guarantee that the system data processing section moves reliable and stablely, except itself carrying out the check of necessary mistake proofing processing and robustness, software architecture also provides necessary protection for it and has hidden.Though system module provides Data Source for user interface and database storing, it is transparent for these two parts.All visits to system data all are to finish by this single interface of exchanges data controller, have guaranteed the consistance and the stability of data.
The front mentioned this air traffic control set have carry out automatically that flight collision is surveyed and auxiliary allotment, flying quality upgrade automatically in real time, any-mode sorts automatically, multiple instruction input and to sky commander record, fast automaticly transmit messages, historical record playback, the height demonstration of C pattern and prompting, statistic of classification inquiry, process are single multiple function such as freely drags.These functions all are that the system data processing section can be realized by software, this only with regard to above-mentioned carry out automatically that flight collision is surveyed and auxiliary allotment in real time, flying quality upgrades automatically and fast automaticly transmit messages, any-mode simple explanation of realization work of function such as ordering automatically, remaining function is similar with it, has not just described in detail one by one.
1) flying quality upgrades and fast automatic transmitting messages automatically
Exchange by the data in real time with the radar control seat, this air traffic control set is the real-time update data automatically, so that the air traffic control personnel obtain up-to-date flying quality timely, can be more accurate, and implement air traffic control more timely.
In printing flight process single job in the past, the air traffic control personnel can't from the process printed is single, obtain new variation timely flying quality, unless every variation one secondary data, again printed again one fen, perhaps by the radar data integrated display, perhaps exchange the acquisition flying quality with the pilot, the interchange of this flying quality be far from the electronic flight process single increase automatically and data updated is such comprehensively and quick.
This air traffic control set can upgrade the flying height of aircraft automatically, and more helping the air traffic control personnel, to grasp the flight of aircraft timely dynamic, more helps the air traffic control personnel and send control order accurately.It can upgrade the control order that the air traffic control personnel do aircraft automatically on the radar control seat, alleviate the burden that the air traffic control personnel do two parts of instruction inputs.Most importantly, it can also upgrade automatically by the air traffic control personnel and make the flying quality that changes behind the control order (as the landing runway, the location point increase and decrease).
● system is according to current location point time reckoning the place ahead flying quality, if conflict with original plan, system submits prompting automatically to.
● electronic flight process one hand is write the modification runway, causes the variation in air route, out-of-bounds focal point, perhaps directly revises the air route of out-of-bounds point, and system will calculate the place ahead flying quality automatically, and judge whether and conflict in the original plan, and the submission prompting that might conflict.
● directly revise certain location point, time, highly, system will calculate the place ahead flying quality automatically, judge whether and conflict in the original plan, and the submission prompting that might conflict.
Instructions such as input is maked a return voyage, is diversion, is flown nonstop to, wait, system calculates the place ahead flying quality automatically, judges whether and conflicts in the original plan, and the submission prompting that might conflict.
In view of most flight informations and electronic flight process single no matter similar and have interactive getting in touch between them at aspects such as content, forms, so our design and developed and utilized the single function that can partly send (comprising the electronic flight card) flight information of electronic flight process.Do not use on the flight information seat, just on this air traffic control set, use the pattern of electronic flight process list, can send a lot of flight informations, reduced the program of transmitting messages, improved the efficient of work on duty.
2) any-mode sorts automatically
Utilizing the print progress list to carry out in the process of control operation, if a plurality of processes are singly sorted, the flight controller can only be visual each process single, search for these processes and need the data item that sorts on single, it is comprehensively relatively drawn sorting data, move corresponding process then and singly obtain ranking results.This sortord is fully by manually finishing, the process on the single frame of process single more, sorting data is complicated or be subjected to the influence of subjective and objective factors such as asthenopia, causes misordering easily.
The automatic ranking function of this air traffic control set has successfully solved this problem.The sortord that it provides has course line ordering, height ordering, time-sequencing, state to sort and integrated ordered five kinds, as shown in figure 10.Wherein integrated ordered permission controller is designated state, altitude range and time period or its combination independently, to obtain specific ranking results.The layout of the electronic flight process list of candidate regions all is according to a kind of result of rule compositor wherein.When the number of process list has taken place to change or the single data that participate in ordering of certain process have taken place to change when needing rearrangement, system can automatically recomputate sorting data and according to this Refresh Data ranking results.
3) carry out flight collision automatically and survey and assist allotment in real time
When using the print progress list to carry out the control operation, the flight controller need singly compare each process, finds out possible conflict and also further judge according to the conflict decision rule from numerous and complicated process forms data.Because flight safety in the flight collision serious threat, the flight controller has to pay close attention in time any a pair of possible conflict.This situation might occur: the controller has spent and has gone to survey a pair of possible conflict for a long time, but in fact this conflict does not exist, and really the conflict of existence possibility is out in the cold or have little time inspection.Obviously, this artificial conflict method of discrimination all is difficult to satisfy actual needs on efficient still is accuracy.
In this air traffic control set, conflict detection mechanism can be calculated the data of each electronic flight process list according to the relevant regulations of " People's Republic of China's flight interval regulation ", the position of location conflict quickly and accurately, and the information such as time, position of conflict are presented to the flight controller in eye-catching, clear and definite mode, make the flight controller can handle flight collision more accurately and timely.
In the implementation procedure of above-mentioned functions, this air traffic control set will with whole radar control system swap data in real time.Flight controller's various control operations, the data of the operation of transmitting messages will send the radar control system in real time to, and the radar control system will send radar data, new process forms data to air traffic control set in real time.The transmission of these data and reception are all undertaken by communication module.
The difference of communication module among the present invention and common communication module is: the transmission of data and reception and flight controller's control operation is concurrent, sending and receiving to influence the ongoing control operation of flight controller, and ongoing control operation can not influence the transmission and the reception of data.Simultaneously, this module will be handled the data perturbation that influence of various factors such as communication line, the concurrent transmission of data may cause.The design of communication module must be considered above various factors.This module is mainly finished following function:
1) data send: flight controller's various control operations, the data of the operation of transmitting messages are sent to the radar control system.
2) Data Receiving: receive various data from the radar control system.Be at random the opportunity that the radar control system sends data, and the state of the necessary continual supervision communication apparatus of communication module can not missing data.
3) data check: be subjected to communication line and other influence of various factors, the data of transmission have error code and exist.Communication module joins in the transmission packet according to the content generation check code of the packet that will send and with this check code before sending data.After receiving the packet that the radar control system sends, generate new check code and compare according to packet content with check code that packet carries.If two check codes are identical, then illustrating does not have error code in the packet.Otherwise illustrating has error code to exist in transmission course, abandons this packet and notifies the radar control system to resend.Data check adopts the DES algorithm in this module, guarantees the uniqueness and the accuracy of data check.The workflow of Data Receiving and transmission as shown in figure 11.
Data communication has adopted dual mode: serial communication and network communication.The advantage of serial communication is to realize simplyr, sends and receive reliable.Its shortcoming is that communication distance is short, and recommending communication distance is 10 meters; The speed that transmits and receive data is lower.Because this air traffic control set is located in the control rack with the radar control system host, distance is about 1 meter only, be significantly smaller than the communication distance of recommendation, the communication baud rate of this moment can stably remain on more than 38400 bps, be that per second can transmit 4000-5000 byte, can satisfy the demand of data transmission in the control operation fully.The advantage of network communication mode is that the efficient of transmission is higher, and the data volume that each packet effectively sends is bigger.Its shortcoming is to realize comparatively complexity.Communication module provides this two kinds of communication modes.
The transmission of data and reception are two independently threads in this module.Owing to can't learn when the radar control system can send data, so receiving thread waits pending data always, and then carries out other processing.After communication module receives data, will inevitably disturb ongoing control operation if carry out the operation of data by force and show.So this thread is just put into pending data queue with the data that receive, and send the notice that data are sent to system, carry out data by the exchanges data proxy module then and unpack processing, judgment data flows to and carries out suitable scheduling, solves control operation and communication data and handles concurrent problem.Send thread and when not having data to send, be in dormant state, for more resources is saved in the operation of other threads.Read the outgoing data formation when receiving outgoing data this thread of when notice, carry out a series of other processing again.To detect data check wrong when the radar control system, and this thread starts retransmission mechanism, resends data.
Specific implementation to electronic flight process list is illustrated above.The implementation of following brief description electronic flight card.The card that flies is the common name of using " transporter ferry flight registration card ", " redeployment of fighters flight registration card " and " interior a, card of flight registration outside the venue " in the present work on duty of Control Centre at different levels.The effect of flight card and the total registration form of flight planning is basic identical, mainly is the registration flight planning, use for the air traffic control personnel, but the flight card also has following several effects except the registration flight planning:
● by record, can also part grasp flight dynamically to course line, training flight airspace and flight time;
● can be used as a kind of means that contact is let fly away;
● can put down in writing brief control order;
● can circulate a notice of the record of various flight situations.
The electronic flight card is to be carrier with the computing machine, shows output flight card by display.Form is fixed on the picture, and wherein with good grounds air traffic control need be by COMPUTER CALCULATION and the parameter that shows, and also having some is blank lattice, by controller's manually input as required.Some content of electronic card allows the manual amendment.Figure 12 is in the field, the synoptic diagram of the card of flight registration outside the venue.The form of other " transporter ferry flight registration card ", " redeployment of fighters flight registration card " is basic identical with it, only is that color is inconsistent.
The process that realizes the electronic flight card among the present invention and the process of realization flight process list are the difference that consistent, different place only is display format basically.Therefore, the technological means of realization electronic flight process list above-mentioned can be used to realize the electronic flight card fully, and the change of display format is very basic software engineering, has not just given unnecessary details at this.
In the process of above-mentioned realization electronic flight process list and electronic flight card, we have formulated the unified electronic flight process list and the interface of electronic flight card according to demand, and they have all used unified format.Because the electronic flight process of each type is single and the electronic flight card all has its specific purposes and content, being doomed various processes structure, content, display styles and the data layout single and card that flies all has bigger difference.If each electronic flight process is single and the electronic flight card is all realized by programming, the electronic flight process of a large amount of forms and kind singly and the electronic flight card will cause the extreme expansion of code and the unordered accumulation of the framework inclination that causes thus, structural relation confusion, code and robustness, reliability such as weaken at a series of problems.
For addressing this problem, the solution that we adopt is: electronic flight process form single and the electronic flight card is based on description, be we to the electronic flight process of certain type single and electronic flight card do special the qualification, and be that the information such as identification form, each hurdle destination locations of size to it, tone, each column are carried out suitable description.These information all are stored in electronic flight process list and the electronic flight type of card description list.
When this air traffic control set moved, it read the description of electronic flight process list or electronic flight card from this description list, and described according to this and dynamically to generate electronic flight process list or electronic flight card.Any supposition is not done to electronic flight process list or electronic flight card by system, and is only described.A source describing the data of electronic flight process list or electronic flight card is a dictionary table.Dictionary table must comprise the stable data core of system, for other data of description provide the word source.Such as " the identification form is a height layer ", we are with the member of noun " height layer " as dictionary table, because the definition of height layer is very clear and definite, immutable, its form must be the form of " SXXXX ", and meets the regulation of relevant criterion.Another source of data is electronic flight process list or the electronic flight card development platform-StripStudio that we provide in the description list.The user only need draw each column of an electronic flight process list that oneself needs or electronic flight card and or flight card single to process on this platform attribute is provided with, developing instrument just can write the data of description of the type electronic flight process list or electronic flight card in the description list, reads dynamically to generate electronic flight process list or electronic flight card for software systems.Single or the card that flies has consistent style, interface appearance and data layout with the process that shows in the electronic flight process list of this developing instrument exploitation or electronic flight card and the air traffic control set.This process as shown in figure 13.
The above-mentioned electronic flight process of mentioning single and the implementation method of electronic flight card and the occasion that equipment obviously is not limited to air traffic control.After carrying out certain adaptive change, it is Guaranteed that this technology also can be used in the robotization in a plurality of fields such as electric power, traffic, commercial production.Therefore, for a person skilled in the art, the various conspicuous change of under the situation that does not deviate from the spirit and scope of the present invention it being carried out is all within protection scope of the present invention.
