Abstract:

In order to assist the tower controllers in making decisions and improve the safety of aircraft operation, an airport terminal area monitoring system is proposed based on ADS-B data. Firstly, by analyzing the system architecture characteristics based on system requirements, taking advantage of OOPN's flexibility and easy modular design, the overall complex system was divided into modules and a subsystem model was established. According to the interaction between subsystems, a simplified model of the overall system was established, and the reliability of the model was analyzed. Secondly, the ADS-B real-time data transmission engine was designed to improve the efficiency of data use by wireless transmission, and realize effective data transmission between virtual system and external entity. Finally, based on the Unreal Engine 4 (UE4) platform, the system for virtual reality simulation was implemented to monitor aircraft in real-time within a certain range around the airport. The analysis and test show that the modularity and reliability of the system are improved by the modeling of the system. The analytical nature of the logical structure of the system is enhanced. The terminal area monitoring function of the constructed system can be implemented safely and reliably.
