Design And Implementation Of Digital Flight Strip In Air Traffic Control

Xi’an Xianyang International Airport is located in the Chinese inland center.It’s the largest air traffic hub in the northwest of China.In 2012,its flight volume rise rapidly along with the new airport tower and the double runway put into use.In the last summer transportation,the tower’s daily flight has reached its peak of recent years,which make the airport ranked eighth busiest airport in China.In addition,the rapid development of economy and technology has brought unprecedented pressure on air traffic control work in recent years.In order to adapt to the ensuing security problems,the digital flight strip came into being.It’s appearance reduce the human error greatly and prevent the situation of "wrong","forget" or "omission" effectively in air traffic control work.Then a great deal of flight information can be processed by scientific calculation and management.As a very important tool in air traffic control work,the digital flight strip Mainly used for: guide the aircraft taxiing to the runway from the parking position,and transfer the flight to the incoming control until the flight takes off;guide the landing aircraft taxiing to stop position.The controller can transfer flights,information,runway management and alarm processing between seats by using the digital flight strip.Based on the Operating environment of Xi’an Xianyang International Airport’s control tower,this thesis studies the digital flight strip in following aspects:The design principles and methods of digital flight strip are studied in this thesis from aspects of reliability,availability and maintainability.The thesis lists some technical difficulties in the system’s design process.Secondly,It proposes solutions to existing technical difficulties in the work of software design.The core components of the system are also designed and implemented.Because of all the system’s subsystems and function modules interconnect through the network.Each of them provides specified service and requires different data,and all this data are exchanged over the network.If the all the nodes of system interact data with each other without any supervision,the network storm will come.When one of the nodes has some problem,it may bring the paralysis to the whole system.In order to make the function module focus on the business function and make the system has high reliability and expansibility,the system uses message changer to separate underlying communication parts from functional modules.It has the function of isolation fault.When one node of a host logs off or has some fault,it only causes the loss of the information interaction between with the system.And it will not affect the other communication nodes,then ensuring the system’s normal function of communication and service.Lastly,it analysis the digital flight strip’s application of eath seat on the tower of Xianyang airport.Based on the status of flight data connection,the thesis summarizes some questions,and puts forward the operation mode of the integrated tower,which is the main developing direction of air tube systems.
