The Design And Realization Of ATS Train Tracking

Automatic Train Control (ATC) system of Urban Rail Transit includes Automatic Train Protection (ATP) system, Automatic Train Operation (ATO) system and Automatic Train Supervision (ATS) system.As an important subsystem of CBTC system, ATS subsystem reflect the exact location of the train, update the status of the online train and is responsible for supervision and control of all operating trains.The station graph with ATS as the core is the main interface of the ATS system,it contains the information of the train and a lot of dynamic information of the device status.By means of deploying the icons of station device, offline device data and designing of online status code of device-control,the station graph will provide a complete device basic data and scheme of online display of the ATS system.Based on the train simulation platform of the ATS system,this thesis will elaborate the data structure of the offline device and the program of online display of the station graph,deploy complete offline device icon and device data of the station graph,desigh online update module based on code of station graph device status,analyse data flow of online station graph,process train data in the simulation and achieve the online update of the status of the station graph. This thesis is based on the object-oriented programming ideology,the station graph desighed has a preferably platform compatibility,and manage the device data and device icon through two modular parts. After the online verification of ATS simulation platform,the device data and device control code is correct and effective,the online status of station graph also runs in a preferably condition.This thesis uses actrul line data as the input data,as a result to has a preferably reference value.
