Design And Realization Of The Comprehensive Maintenance Service System Of The Train Control Center Based On QT

The Train Control Center(TCC)is the core equipment of the passenger train line control system.It mainly accomplishes functions such as track circuit coding,storing and calling of LEU message,lighting control of interval signal,inter-station security information transmission(interval track circuit status,relay station temporary speed limit information,interval blocking and direction conditions,etc.)and so on.The Train Control Center Maintenance Terminal as a visualization unit of the Train Control Center,is a man-machine interface that monitors the normal operation of the TCC and timely understands the communication status,equipment failure,and other information.The traditional Train Control Center Maintenance Terminal is in the work mode of one station,one train,and each maintenance terminal is relatively independent.When a problem occurs,the Railway Administration and the Electricity Services Department are not convenient for centralized management.The Train Control Center Comprehensive Maintenance Service System mainly compensates for that.It can display the related information of the Station Control Center of the Road Administration Center and the Electricity Services Department on an integrated maintenance terminal interface,and be placed in the control center of the Road Administration and the Electricity Services Department.In this way,when an emergency situation occurs,Railway Administration,the Electricity Services Department and the work area will simultaneously grasp the situation on the site,coordinate the coordination and command,and deal with the on-site problems of the Train Control Center in a timely manner.The analysis and processing of failures is straightforward,efficient,fast and accurate.It belongs to a comprehensive and modern maintenance center maintenance system.This dissertation mainly studies the design and implementation of the client software of the Train Control Center Comprehensive Maintenance Service System,and uses QT as the development tool.According to the waterfall software development process,the system requirements are first proposed to explain the functions that the software needs to implement.Secondly,the software structure is designed,and the client software architecture is hierarchically divided into modules according to functions,and the functions and processing flow of each module are designed.Then the software structure is designed,and the client software architecture is hierarchically divided into modules according to functions,and the functions and processing flow of each module are designed.The last is the functional testing of the system,setting up the test environment and testing the main functions of the client software.The functions required by the Train Control Center Comprehensive Maintenance Service System were finally realized.
