Abstract:

Considering the non-intuitive description of information of the traditional aircraft 2D real-time surveillance system in the airport terminal area and the poor man-machine interaction function, a simulation scheme of the aircraft 3D real-time surveillance system in the terminal area is proposed based on Automatic Dependent Surveillance-Broadcast (ADS-B) data. The real-time data stream transmission mechanism is constructed based on Socket and multi-thread technology to carry out data interaction between virtual and real systems in the way of wireless transmission, which overcomes the limitation of data transmission range of traditional ADS-B receiver and improves the flexibility of ADS-B data usage. Virtual simulation of the monitoring system is realized through the virtual reality technology. On account of the track breakpoints and corner points in the simulation process, an interpolation method that combines the course-time information in the data with the Bezier curve is proposed. On the premise of system real-time performance, track interpolation is carried out at the breakpoint and corner point to realize smooth display of the track. The results show that the proposed method can improve the smoothness of the aircraft trajectory in the system while ensuring real-time performance of the system.

Key words: system simulation, automatic dependent surveillance-broadcast (ADS-B), virtual reality, trajectory interpolation, smooth trajectory
