Design And Implementation Of Integrated Supervisory Control Platform With Traffic Dispatch

Integrated Supervisory Control System of urban rail transit information sharingplatform has been the development tendency of rail transport automationtechnology,which supports functions of information sharing and monitoring inprofessional systems. Currently, in considerations of system security and real-timecharacteristics, traffic dispatch function is usually provided by separate Automatic TrainControl (ATC) systems, which leads to poor linkage problem between informationsharing platform and traffic control systems. So that this paper designs and implementsthe Integrated Supervisory Control System with traffic dispatch function, and builds aIntegrated Supervisory Control Information Sharing Platform with deeply integratedtraffic dispatch, so that the professional resources and information of railway traffic inall lines can be shared and exchanged in maximum extent,which achieves the functionsof collaboration among different professional systems. The details are as follows:(1) After systematical research on system type and architecture of SCADA railtraffic Integrated Supervisory Control System, this paper describes the requirements ofthe structure, function and performance of ATS sub systems in ATC systems. Based onthis, we make a deep analysis on the feasibility and advantages and disadvantages onthe traffic dispatch function integration in SCADA Integrated Supervisory ControlSystem of rail transportation.(2) Combined with the current SCADA universal design architecture of IntegratedSupervisory Control platform, we give a feasible realizable traffic dispatch functiondesign proposal. Based on the real-time database which is the core part of IntegratedSupervisory Control System, we builds ATS professional library in IntegratedSupervisory Control platform, designs and implements the core functions of TrainMonitor and Tracking, Auto Route Setting and Auto Train Regulation. And thesimulation to the realization of traffic dispatch Integrated Supervisory Control Systemshows the feasibility of Integrated Supervisory Control Information Sharing Platformwith Traffic Dispatch.(3) On the design and implementation process of Integrated Supervisory ControlSystem with Traffic Dispatch, this paper does improvement to the general train trackalgorithm, which enhances the real-time characteristics of train tracks, and letIntegrated Supervisory Control System with Traffic Dispatch has stronger real-timeand fault-tolerant characteristics and faster failure recovery capabilities. The research achievements of this paper can be used to build the integration ofinformation sharing platform for city rail industries in order to realize automation of railtransportation industry information.
