Research And Simulation On ATS System Of Fully Automatic Depot

With the development of FAO(Fully Automatic Operation)technology,fully automatic depot has emerged as the times require.It has the advantages of improving the ability of trains to enter and exit of the depot,reducing the work intensity of dispatchers,and improving the safety and reliability of the system.It configures the same signal system as the main line and overcomes the inefficiency of conventional depots due to manual dispatching and manual driving.In this thesis,fully automatic depot is researched,and ATS(Automatic Train Supervision)simulation system of fully automatic depot is built to realize the basic functions and operation scenes simulation.Firstly,the composition,overall layout,operation scenes and system configuration of fully automatic depot are introduced.The differences between fully automatic depot and conventional depot in the operation organization are analyzed.The structure and the main functions of ATS system of fully automatic depot are studied.Secondly,the overall design and detailed design of ATS simulation system of fully automatic depot is introduced.The overall design mainly designs the system structure,function and database,as well as the key technologys of the system application,including the analysis of the routing control process,the station-type data structure based on the doubly linked list,and the route search algorithm based on the heuristic search.The detailed design specifies the design and implementation process of each sub-function module of ATS system of fully automatic depot,including main interface of the depot ATS workstation,train tracking module,routing control module,timetable management module,train automatic entry and exit module and automatic shunting module.Among them,routing control and timetable management are two major functions in the system.Routing control module is based on the station-type data structure and is implemented by the heuristic search algorithm.Timetable management module applies an automatic generation strategy to automatically generate the timetable.Finally,ATS simulation system of fully automatic depot is tested to verify the basic functions of this system,and to simulate the main scenes such as the automatic entry and exit of the depot and the shunting operation.The system test results are favorable,to achieve the intended simulation purpose.
