Research On Cognitive Modeling For Train Speed Tracking

The increase in the running speed of railway trains puts forward higher requirements for the speed control of train drivers during driving.In a complex train operating environment,how to achieve more accurate speed control to ensure driving safety and efficiency is the train driving interface Issues that must be considered in design.Train driving is a one-dimensional speed control.The efficiency of the human-machine interaction between the driver and the speed display interface will directly determine its performance on speed control.The speed interface design that does not meet the cognitive operating characteristics of people is likely to induce fatigue and cause human error.,affecting train running on time.This article takes the high-speed rail joint fund project "High Speed Train Autopilot Theory and Key Technology Research" as the background,starting from the impact of the train speed interface on human cognitive behavior,using the cognitive behavior modeling method,from the qualitative and quantitative aspects To study human perception,attention,memory,judgment,decision-making and operation performance in speed control,that is,speed tracking tasks,and to evaluate the ergonomics of the speed display interface based on this,the main work of the thesis is as follows:(1)The cognitive task analysis method is used to analyze the cognitive behavior process of the speed tracking task.The cognitive process of the speed tracking task is divided into three parts: visual perception attention,information processing and operation response.The information processing model of the speed tracking task of extraction ? judgment decision ? operation execution.(2)Aiming at the key factors influencing the speed visual perception attention in the cognitive process of speed tracking tasks,the effects of these factors and their different combinations on the performance of speed tracking tasks are studied through ergonomic experiment design.(3)Quantify the information of the train speedometer,establish the mapping relationship between the amount of information and visual perception attention in the speed tracking task,and build a cognitive computing model of "visual perception ?knowledge extraction ? judgment decision ? operation execution" on this basis,And verify the model through qualitative and quantitative methods.
