Study On Dynamic Organization Method Of Head Up Display Information On High Speed Train

In the process of high-speed train driving,the driver should always pay attention to various display instruments in the cab and complete a variety of driving operation.At the same time,they also need to observe road condition.When the driver lowers his head to observe the information on the display instruments,it is easy to ignore the road condition and vice versa.With the increase of the speed of high-speed train,the above security problem is becoming more and more serious.In order to solve the safety problem,it is possible to introduce a head up display system into the cab of high-speed train which has been widely used in the field of aviation and automobile.Head up display can reduce the frequency of drivers' bow and gaze shift.There are many display equipments and information in the cab.If the driving information is presented on the head up display system,it is necessary to conform to the driving characteristics of the high speed train.It is necessary to study the information organization method of the head up display system in high speed train.This thesis study a dynamic organization method of head up display information on high speed train,and the main work is as follows:(1)This thesis uses eye movement analysis,video analysis method,completed the task analysis of CEMU drivers of Shenda line.The actual process of driving was divided into departure task,high-speed driving,passing the neutral section,stop parking by consulting EMU driver operating manual and other documents.(2)On the basis of the above,this thesis proposes a of dynamic organization method of head up display information based on high speed train driving task.According to the different driving tasks,the method can dynamically organize and present the HUD interface.This thesis also completes the color and shape coding of the head up display information.(3)In order to verify the validity of the proposed dynamic information organization method,an experiment was designed and implemented.The experiment platform was designed and a dynamic information display interface program based on driving task was completed.A simulation platform based on high speed train driving simulator was built.By using this platform,the validity of the dynamic information organization method was verified by combining the reaction time,driving performance,eye gaze behavior and subjective load value.The results show that the proposed dynamic information organization method based on driving task is superior to static information organization in driving performance,visual search,and psychological load.The research results can provide theoretical basis for the application of head up display system on high speed train.
