Research And Design On Metro ATS-Mimic Communication And Control Software

With the development of metro traffic,the needs of surveillance controlling and monitoring in integrated operations are growing.The Mimic screen is the analogue screen for orbital traffic integrated monitoring center.It brings a clear,accurate display of the important information of the train signal control system,ATS and orbit.And it's one of the essential devices in the integrated surveillance system.However,for security reasons,the ATS system and the Mimic control system all have separate communication protocols and control protocols.There is a lack of communication interfaces and protocols convert software.In this background,this thesis has started research and design on the communication and control software based on SOAP and has studied the real-time data collection of the ATS system and the real-time control of the Mimic screen.This thesis does some works,including:1.On the background of integrated monitoring for metro networks,this article analyzed the needs for trains and orbits to data display.By analyzing ATS's communication interface and Mimic screen control interface,this thesis designed the structure and function of the system.2.Through analysis of SOAP,this thesis analyzed ATS's system interface,the GENA protocol,the parsing and the data and modeled the data objects to collect the real-time ATS data.3.Through analysis of Mimic control protocol,this thesis designed the TCP/ IP communication interface to realize the response to control commands and control states.4.Through software testing and running,this thesis analyzed the real-time and reliability of data processing and solved the problem of the ATS system's GENA protocol and the Mimic control protocol.Through the actual operation of Shanghai Metro,the system realized the real-time communication between ATS and Mimic.The processing capacity of per ATS message reaches an average of 81.3 millisecond.
