Research On Automatic Train Regulation In The Double-track Automatic Block Section Of The Conventional Railway

Train rescheduling is the main work of dispatchers of the conventional railway,which occupies most of the time and attention of the train dispatchers.In order to explore how the train dispatcher carries out the train rescheduling,this thesis makes a detailed investigation of the operation content and methods,summarizes the main factors affecting the train rescheduling and the train rescheduling measures taken by the train dispatchers in view of different interference scenes.It is found that although there are many factors involved in each train rescheduling,the rescheduling methodsof train rescheduling are highly repetitive and it has certain rules.Therefore,on this basis,the research on automatic train regulation can be carried out for the conventional railway.The main work of this thesis is as follows:(1)Combined with the actual work content of the train dispatchers,this thesis summarizes the specific work content of each shift of the train dispatchers,and analyzes their main repetitive work content.And this paper combs the relationship between the train dispatchers and relevant operators,and makes a statistical analysis on the work attention distribution of the train dispatcher of the conventional railway under four conditions.On this basis,it is necessary to study the automatic train regulation of the conventional railway.(2)Based on the summary of the rules and regulations that the train dispatcher should follow when rescheduling train,this thesis further puts forward the adjustment rules of train class,on the basis of existing trains class,by defining finer class,the train class of the same speed type is subdivided according to its importance,to achieve the purpose of the flexible train reschedulingand provide rescheduling rules for automatic train regulation.(3)The virtual concepts of "train number river" and "train storage pool" are proposed to visualize the adjustment and sequencing of train class and solve the problems of reception frequency at special stations such as marshalling yards,technical stations and key freight handling stations.Through the comparison and sorting of train class,the purpose of key train release is realized,and the order of train operation is guaranteed.The reasoning and judgment link of using the intervals of high-classtrain to move low-class train is set,so as to avoid the situation of low-class train hindering high-class train.(4)Through the classification and segmentalization description of train routes occupied in the station,as well as the calculation and comparison of the occupying time,the interval of train departure time in the station is calculated,which solves the difficulties of conflicting train routes occupied and unreasonable use of arrival and departure lines in the process of train rescheduling.(5)By analyzing the fault disposal process of train dispatchers,the pain points and difficulties in the process of train rescheduling are found,then it is concluded that reducing the workload of train dispatchers,improving the adjustment quality of train operation plan and eliminating inter station barriers can be achieved by realizing the automatic train regulation,and the achievable target functions of the automatic train regulation are summarized.At the same time,the train rescheduling methods adopted by train dispatchers in different scenarios are summarized and compared,and the dynamic rescheduling models of passenger train and freight train are proposed.Taking some stations of Jinshan Line as an example,the simulation experiment is carried out to verify the feasibility of the automatic train regulation of conventional railway.
