| Beijing Capital Airport is one of the busy airports in the world.In recent years,the number of flights has increased year by year and it reached 606,000 flights in 2017.The increase in the number of flights has led to more and more frequent surface activities such as aircraft and vehicles,busy surface operations,and complicated surface activities and management.As a result,runway incursions and surface conflicts occasionally occur,putting tremendous pressure on air traffic control work.Therefore,monitoring the operation of aircraft and vehicles efficiently,preventing runway incursions,improving safe operation efficiency,and ensuring the on-time rate of flights are receiving more and more attention.The Advanced Surface Movement Guidance and Control System(A-SMGCS)is widely applied.Based on the surface operation of Beijing International Airport,the following research on the advanced surface movement and control system are carried out in this paper:1.The technical basis and theory of the A-SMGCS system are studied and analyzed,the development history is outlined,and the relevant requirements of ICAO are discussed.In addition,the several common surface surveillance techniques are analyzed,including surface movement radar,multi-point positioning,ADS-B,etc.The surface surveillance signals are the data source of the A-SMGCS system and are processed and displayed to the air traffic controller to achieve the purpose of monitoring aircraft and vehicles.2.According to the characteristics and design requirements of Beijing Capital Airport,the design level of the A-SMGCS system is determined.On this basis,the design principles of the system are discussed.The overall hardware architecture of the system is built and the specific composition of the system is analyzed;The main functions of the application software are designed,including monitoring,control,routes planning and guiding;Due to multiple integrated data sources of the system and more interaction with other systems,the information integration is studied and the type of system input information and output information are determined.Finally,according to the actual operational requirements,the technical indicators of the system are established.3.According to the functional requirements that the system should meet,the overall functional composition of the A-SMGCS system software is planned,and the software is divided into 20 functional modules for installation and maintenance.The software design of the system involves a lot of content,but the routes planning is highlighted in this paper.In order to solve the route efficiency problem,the airport network layout is studied,the airport network model is established,and the concepts of taxiing path,taxiing route,path segment and path key point are defined.The routes planning is divided into automatic routes planning and manual routes planning,and the automatic routes planning is divided into inbound,departure,deicing,and the optimization processing method is discussed for these situations.4.The future direction of the system is discussed,including two aspects: First,based on the actual operation,the intelligentization and rationalization of the route accumulate certain experience routes and establish an experience routing library,which makes routes planning more reasonable.Second,the warnings are more efficient.Combined with cloud platform established by the air traffic control system,the speech recognition for regulatory orders is developed.Early warning detection is carried out by identifying regulatory orders and combining system processing.For example,the command to cross the runway is recognized,but at the same time,another aircraft lands and the system generates an alert. |
