Research On The Train Report System In ATS Based On CBTC

At present,with the rapid development and increasing size of our city,the urban rail transit play an active role to optimize the city structure and resolve the heavy traffic jam,becoming the development object of the public transport in the future.In china,the CBTC due to its significant that improve the operating efficiency and informative of the train has been widely adopted.Ats system as the top layer of the ATC system is mainly to control and supervision the position or status of trains.The train report is one of the core functions of the ATS system in recognition and tracking.It is responsible for the communication of VOBC with WLAN and the interactive information and defense the threats by RSSP-?,such as train position,train status and the control command.And generate the report data by logic report,ATO stable report,interlock occupied report and the safe door,accomplishing the updating of train state,issuing the late point,and drawing of the diagram.This paper is based on the project "The second phase of Beijing subway line 8 ATS system".The contents include:firstly,the research on the function and structure of ATS system that elaborate the hierarchical structure and defense technology of RSSP-II,analyzing the function demand of train report.Then,paper analyze and implement the communication agent,and the function about generating report,updating state of train,calculating the time of late.In order to verify the technology of train report,based on the simulation platform of ATS,paper have designed the structure of VOBC module and achieved the communication connect and data interchange.Research results show that the train report technology can process the communication based on the RSSP-?.and accomplish the updating train state,sophisticating the operation report,drawing of diagram,issuing the late point and the transmission of ATO command by means of report technology.The research result has a certain value in engineering.
