The Research Of The Mobile Quadrotor Training Platform Design Based On Situation Cognitive

In recent years,with civil uav products sell like hot cakes,related technology advances,more uav rotorcraft technology rapid development,quadrotor has become one of the people's favorite smart products.As the propeller rotor speed of the quadrotor is fast,the flight safety becomes more important.Most of model aircraft enthusiasts and training organizations choose to use quadrotor training platform for flight training.First of all,this paper carries out a study,from the perspective of the situation cognitive theory,of the main factors affecting the user's situation cognitive in the quadrotor training platform based on Analytic hierarchy process(ahp),and puts forward a solution about the quadrotor training platform design based on a better situation cognitive.Through the prophase design research work,we collected and organized the demand of the target user groups,behavior habit and typical cognitive activities.It was explicit through the user's cognitive model,which was used to guide the design process.Furthermore,in the design phase,the method of prototype testing was used to identify the problems and conduct the iterative design process.Adding situation cognitive theory to quadrotor quadrotor virtual training platform design,we used Unity 3d engine to develop the quadrotor training platform called Flight Training based on situation cognitive theory.We solved some typical problems during the training platform development,such as slow loading virtual flight scene,model switching flickers and so on.Finally,we carried on the contrast experiment on the training platform,analyzed the experimental data,and summarized the experimental conclusions.The experimental results show that,the learning effect of the virtual flight training platform based on the situation cognitive theory is obvious.Pressure reducing,distribution of attention,and cognitive biases all have different degrees of improvement.The more difficult task of virtual training system become,the more obviously the operation effect increase.The innovations of this paper include the followings:1)By exploring the situation cognitive behavior of the quadrotor users,we built the situation cognitive model of quadrotor users,in the view of the difference between general users and professional users.2)Using analytic hierarchy process,we analyzed the main factors influencing the users'situation cognitive,and put forward the principles of virtual quadrotor training platform design based on the theory of situation cognitive.
