Research On The Runway Incursion Prevention System Based On Sensor Network

With sharp increase in current air transport activities, there is a big hidden danger of airportsurface safety, the airport surface traffic automation control is particularly urgent. This paper designeda runway intrusion prevention system based on Sensor Network in view of the existing defects ofmonitoring and control mode，and then the traffic situation reconstruction,the control strategy ofrunway incursion were studied.This paper established the target of runway incursion system based on sensor network firstly, andanalysised the functional requirements of the system, and then constructed the overall framework ofthe system from the structure. The system was divided into several module that were detailed analysisabout the corresponding function.Then in order to realize the system function, the third chapter made a detailed study of the trafficsituation reconstruction. This chapter established runway traffic running continuous model from theperspective of dynamics and kinematics firstly, and runway movement model based on Petri nets wasestablished according to runway operating rules and the layout of sensor network. This paperproposed hybrid model of aircraft running based on sensor data by synthesis of the continuous anddiscrete model. Through compared the predicted data of continuous model, the predicted data ofhybrid model and the actual data by case, the accuracy of hybrid model is verified about the trafficsituation reconstruction.In order to achieve the automatic defense of runway incursion, the fourth chapter studied thecontrol strategy of runway incursion. Then the marking control model is transformed into the stateprohibits problem to design controller, and the priority control strategy is put forward according todisable concurrency events. On this basis, the control command of stopping lights can be decidedbased on the state of transition, and the corresponding decision-making algorithm is put forward.Finally, a simulation example demonstrates the effectiveness of the runway incursion control strategy.This paper finally introduced the principle of runway intrusion defense system and the processestablishing. The simulation system based on VC platform and STM32control module established thesimulation interface and the backstage sand control system, realizing the double functions of thecontroller monitoring runway operation condition visually and the runway incursion of automaticdefense.
