It is support platform to rely AFTN, and the general access way in end of AFTN is as shown in " access way Figure 1A FTN telegraph networks ".
Transit telegram machine is generally placed upon ATM Bureau, using the asynchronous RS232 interface of duplex, transmission rate up to 300,600,1200,2400,
4800,9600bps.Airport, airline need the communication interface of the RS232 transit telegram machine, pass through Modem or electric current loop mode
It is linked into respective computer room.Before the eighties in last century, blank pipe, airport, airline are integrated organization, three lists of initial stage
After the separation of position, building is generally all mutually connected in same plot, uses the electric current loop technique of 1.2KM communication distances that can ensure thus
Relevant communicating requirement；Modem modes are in practice because traffic rate is low and poor anti jamming capability, less use.
Every unit for needing to access AFTN telegraph networks, needs individually to ATM Bureau's application, meanwhile, often receive and dispatch a report
Text, minimum 2 yuans, high will receive tens of members.By the flowmeter of the old airport in Kunming 17,000,000 passenger people times/year in 2009
It calculates, the up to ten million RMB of message expense.Meanwhile AFTN issues the message on airport, to be carried out by keyword of three character codes on airport
Forwarding, the code on an airport must be unique in principle, needs relevant international organization to apply, if KMG is Kunming airport
Three character codes are related to domestic and international all multisystems, for this purpose, flight, passenger, the luggage etc. that can not possibly replicate KMG using new code
Information.
In general, in the resettlement of strange land airport is built, typically manual simulation's Data Data, then by robot program according to
The time of design pushes the information such as flight, passenger, luggage, and the test of new airport information system is carried out with this.In this way, test run
In there will not be the case where occurring in a large amount of actual motions, such as the flight density of flight peak period, period, daily number,
And the information such as abnormal conditions that may be present in operation.The mistake and missing of actual conditions information, after practical transition, newly
The defect of system can fully be exposed, and then will produce the risk for influencing airport production operation.
At a distance of more than 20 kilometers, new airport will carry out simulation survey using the AFTN information on old airport in real time on Kunming the old and new airport
Trial operation faces two problems：First, transmission range overlength, cannot use existing communication mode；Second is that should not apply new
Airport station code is directly accessed AFTN nets with this.
Invention content
Present invention aim to the AFTN information real-time synchronization on old airport to new airport.Daily by new Airport information
The result of system dry run is compared with the result of old airport actual motion, by handling true flight and psgrs. No. of
According to system test perfect, improve using Flight Information integrated system as the fault-tolerance of the dozens of professional system of core, strong
Strong property.Meanwhile depth training and operation flow break-in are carried out to operating personnel in conjunction with information such as actual flight, passenger, luggage,
With find various aspects there are the problem of and find out solution.
The technical solution adopted by the present invention is first, to use RS-232 " a pair of four Phototube Coupling hubs " (such as " figure
Shown in four Phototube Coupling hub shapes of 2RS-232 a pair ") realize a RS-232 serial port and 1~4 RS-232 serial port
Phototube Coupling communication connection.The RS232 interface of upper interface access message repeater-transmitter uses two the next RS232 interfaces point
The original RS232 interface in old airport and the RS232 interface on new airport are not connected, and the RS232 interface on new airport, which is only received, not to be sent out.Airport
It is mainly the resource informations such as seat in the plane, check-in sales counter, landing gate, the test system on new airport by the information that AFTN is externally provided
In environment, these information cannot absolutely be sent, and otherwise can cause the confusion and safety of flight operation.In this way, also avoiding two
The next RS232 to upper RS232 transmit messages text collision problem, share asking for same AFTN network interfaces to solve the old and new airport
Topic.
Meanwhile the optical fiber and digital special line of telecommunications is rented, the fibre-optic terminus machine of the RS232 access telecommunications at both ends 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 effects of the present invention, in the case where old airport AFTN real time information can be used, Kunming New Airport it is tens of
A special information system has carried out the simulation test operation in (in March, 2011 in May, 2012) more than 1 year.Many systems are potential
Defect is exposed and is repaired in test run, and the fault-tolerance of entire information system, robustness are greatly improved.
This process ensures the new and old airport in Kunming " night transition " once success, and it is the most successful to create world's Large Aeronautic Hub
" night transition " case.
Meanwhile the old and new airport is across the transition upgrading in epoch, business model, the flow on the old and new airport, which have occurred to overturn the heavens, to be covered
The variation on ground.For this purpose, in conjunction with actual flight, passenger, luggage information carries out depth training to business personnel and operation flow is ground
