The real-time display function of train operation status information in the centralized traffic control(CTC)system can help train dispatchers carry out train operation command efficiently.In the new-type train control system,trains operate in a moving block mode and the indication of trains' movement authority in the existing CTC system cannot accurately reflect trains' operation situation.To meet the requirements of train dispatch and command for the new-type train control system,it is necessary to study the display and update approach of train's movement authority in the CTC system.By acquiring precise position data of the trains,this article investigates the calculation methods for the display range of trains' movement authority for both inside and between stations.Based on the display range of trains' movement authority,the starting and ending points of all the strip indication lights are calculated,thereby achieving real-time display and update of the operating trains'position and movement authority range on the CTC terminal interface.This approach has been validated both on the CTC simulation testing platform and on testing operation lines,meeting the standard requirements for displaying train operation status in the centralized dispatch system with the new-type train control system.It can accurately and timely reflect the train operation status,which is conducive to improving the accuracy and efficiency of train dispatching and command.
