Description

Synchronously copy the new airport information system parallel test method of AFTN message

Technical field

The present invention adopts one synchronously to copy AFTN message communication technology and realizes new airport information system and old airport concurrent testing operation method, and particularly the resettlement of Large Aeronautic Hub strange land adopts remote synchronization to copy AFTN message communication technology and old airport concurrent testing operation method to the infosystem updated in building.

Background technology

CAAC's aviation fixed form telegram net (AFTN) bears the domestic air traffic control with the world of Civil Aviation Administration of China, flight dynamically, the message exchange of meteorological and relevant department of the civil aviation authority business transaction of navigation etc.The main body communication network of AFTN Wang Shi China civil aviaton, it is support platform that the production run of Supervision Bureau of civil aviaton, airline, airport (and relevant unit in field) all relies on AFTN, and the general access way of the end of AFTN is as shown in " Figure 1A FTN telegraph network access way ".Transit telegram machine is generally placed on ATM Bureau, and use duplexing asynchronous RS232 interface, transfer rate can reach 300,600,1200,2400,4800,9600bps.Airport, airline need the communication interface of the RS232 of transit telegram machine, are linked into respective machine room by Modem or electric current loop mode.Before the eighties in last century, blank pipe, airport, airline are organizational structures integrally, and after initial stage three units separate, buildings is generally connected in same plot all mutually, use the electric current loop technology of 1.2KM communication distance can ensure relevant communicating requirement for this reason; Modem mode in practice because traffic rate is low and poor anti jamming capability, less use.

Every needs the unit accessing AFTN telegraph network, and need separately to ATM Bureau's application, meanwhile, often receive and dispatch a message, minimum 2 yuans, high will receive tens of unit.By the flow rate calculation of old airport, Kunming 1,700 ten thousand passenger people of 2009 times/year, the up to ten million Renminbi of message expense.Simultaneously, AFTN issues the message on airport, will with three character codes on airport for key word forwards, the code on an airport must be unique in principle, need, to the application of relevant international organization, if KMG is three character codes of Kunming airport, to relate to domestic and international all multisystems, for this reason, new code can not be used to copy the information such as flight, passenger, luggage of KMG.

Usually, in the resettlement of airport, strange land is built, normally manual simulation's Data Data, then push the information such as flight, passenger, luggage by robot program according to the time of design, the test of new airport information system is carried out with this.Like this, in test run, there will not be situation about occurring in a large amount of actual motion, as the flight density of flight peak period, the period, every day number of times etc., and the information such as abnormal conditions that may exist in running.The mistake of actual conditions information and disappearance, after actual transition, the defect of new system can fully come out, and then the airport that can have an impact produces the risk of operation.

The old and new airport, Kunming is at a distance of more than 20 kilometer, and the AFTN information on the old airport of use that new airport will be real-time carries out simulation test operation, faces two difficult problems: one is transmission range overlength, can not use existing communication mode; Two are, should not apply for new airport station code, directly access AFTN net with this.

Summary of the invention

Object of the present invention is exactly will the AFTN information real-time synchronization on old airport to new airport.The result of the result of new airport information system dry run and old airport actual motion is compared by every day, by processing real flight and passenger data, test is carried out to system perfect, improve with fault-tolerance, the robustness of the Flight Information integrated system dozens of professional system that is core.Meanwhile, degree of depth training and operation flow break-in are carried out to operating personnel, to find each side Problems existing and to find out solution in conjunction with the actual information such as flight, passenger, luggage.

The technical solution used in the present invention is, first, have employed the Phototube Coupling that RS-232 " a pair four Phototube Coupling line concentration devices " (as Suo Shi " Fig. 2 RS-232 a pair four Phototube Coupling line concentration device profiles ") realizes a RS-232 serial port and 1 ~ 4 RS-232 serial port to communicate to connect.The RS232 interface of upper interface access message repeating machine, use two the next RS232 interfaces to connect the RS232 interface on the original RS232 interface in old airport and new airport respectively, the RS232 interface on new airport is only received and is not sent out.If resource informations such as the information spinner seat in the plane that airport is externally provided by AFTN, value rack platform, landing gates, in the test system environment on new airport, these information definitely can not send, otherwise the confusion that flight can be caused to run and safety.Like this, it also avoid two the next RS232 and to transmit messages to upper RS232 the collision problem of literary composition, thus solve the problem that the old and new airport shares same AFTN network interface.

Meanwhile, rent the optical fiber and digital special line of telecommunications, the RS232 at two ends accesses the fibre-optic terminus machine of telecommunications, solves the telecommunication problem of RS232.As shown in " Fig. 3 rents the communication link topology of the optical fiber and digital link of telecommunications ".

Beneficial effect of the present invention, when using old airport AFTN real-time information, the dozens of special information system of Kunming New Airport has carried out the simulation test in (year May in March, 2011 to 2012) more than 1 year and has run.The potential defect of many systems comes out and is repaired in test run, and fault-tolerance, the robustness of whole infosystem are greatly improved.This process ensure that new and old airport, Kunming " night transition " once success, creates world's Large Aeronautic Hub the most successfully " night transition " case.

Meanwhile, the old and new airport is the transition upgrading in leap epoch, and the business model on the old and new airport, flow process there occurs earth-shaking change.For this reason, degree of depth training and operation flow break-in are carried out to business personnel, to find each side Problems existing in the business of new airport and to find out solution in conjunction with actual flight, passenger, luggage information.Be mainly reflected in:

the responsibility of each Field Activity user, comprises the item needing special concern between trial run period;

the responsibility of each system contract business;

flow process, personnel placement etc. that system is supported;

report after pinpointing the problems, gather flow process;

regular meeting: the issue-resolution of summing up Resolving probiems situation in early stage, the reason of new problem being discussed, arranging the later stage.

The old and new's integrated system, by the true operation data on the old airport of various interface, reacts the flight operation result on old airport in systems in which really.Parallel running stops after the transition of new airport is enabled.The result display of parallel running, the parallel running target of initial setting realizes completely, parallel running pattern is that the smooth enforcement realizing night transition between the old and new airport provides technology, business, and sufficient preparation has been done in the aspects such as personnel, for the success of transition lays a solid foundation.
