Research And Software Design On Automatic Evaluation Of Train Diagram

A train diagram(train timetable)is a technical document used to represent the time of train operation in intervals and the time of arrival,departure or passing at a station.In the actual process of railway transportation,based on the change of train actual operation time and the demand of transportation,the adjustment of train operation diagram often occurs to adapt to the train operation scheduling.Currently,the train diagram is mainly adjusted by mankind in our country.The work intensity of the staff is large and the limitation is obvious.And the adjustment quality will be affected by the operator’s operational level and working status.To reduce the workload of the staff and improve the quality and efficiency of train diagram adjustment.In this paper,the specific requirements and basic principles of train diagram evaluation are analyzed.And the quality evaluation method of train diagram is studied and an automatic evaluation software is developed based on the data history of subway operation.The train operation diagram is evaluated to provide the adjustment basis for the operator,and further improve the adjustment quality and efficiency.It helps to improve the overall metro transportation efficiency and service quality.The main research contents of this paper are as follows.(1)This paper summarizes and analyzes the research status,advantages and disadvantages of train diagram evaluation system at home and abroad.(2)In this paper,the concept of railway operation and its relationship with operation diagram is introduced firstly.Then the relevant characteristics and analysis methods of train diagram evaluation of metro transit is introduced.(3)The basic static parameter,dynamic parameter,anti-interference stability parameter,passenger service parameter and operation parameter are analyzed,and the corresponding evaluation index system is constructed.(4)The fuzzy analytic hierarchy process is used to calculate the weights of each layer of the index system,which can avoid the disadvantages of complex calculation and consistency detection requirement of the traditional analytic hierarchy process.(5)This paper researches and develops "automatic evaluation software of train diagram" based on Py Charm platform.It is easy to use and the interface of the software is friendly for user.Users only need to input and select parameters according to the software tips to complete the evaluation work,which has good practical performance.Compared with the previous train operation diagram evaluation software,the evaluation index selection function,evaluation data storage,addition and query function evaluation data,as well as the evaluation result recording function are added.And the feasibility and superiority of the software function are verified through the train operation data of a certain actual line.
