[Abstract]:With the rapid development of high-speed railway in China, the design and manufacture of railway equipment has been ranked among the top of the world, and the train operation control system is the basis to ensure the safe operation of high-speed trains. So it is very important to study the new generation train operation control system. This paper designs and implements the database subsystem based on the virtual simulation project of national railway communication and control of Beijing Jiaotong University, "CTCS-3 Train Operation Control Simulation platform". The platform is built in an indoor environment. The operating principle of CTCS-3 class train operation control system is demonstrated by simulating the operation scene of Beijing-Shanghai high-speed railway line. Aiming at the database server and query terminal in the database subsystem of the simulation platform, the functions of the simulation system are analyzed. And the database and query terminal are designed. (1) according to the data communication protocol used in the simulation platform, the data table is designed to facilitate the database management, and the database for user data and operational diagram data in the simulation platform is realized. Scheduling command data processing, with the database subsystem other terminals to complete the data exchange function. (2) the use of multi-thread technology, TCP/IP network communication technology so that the query terminal to establish a reliable network connection; The user login function, account management function and dispatching command query function of the query terminal are designed and implemented by using MySQL database technology. (3) by extracting the train running line data from the database, the coordinate is located on the interface. Drawing the train diagram and realizing the query function of the train diagram; By designing the control of station track, switch, semaphore and other equipment, drawing the simulation platform yard diagram, and processing the interlock feedback information for real-time display, the query function of the station yard representation information is completed. (4) at the end of this paper, The practicability of the designed database subsystem is verified by software test. The interface of each function module of database and query terminal is displayed and the operation flow of the software is explained to ensure the design quality of the system. According to the test results, the database subsystem designed in this paper meets the expected functional requirements and has sufficient simulation demonstration and system application value, which lays a good foundation for the further improvement of CTCS-3 train operation control simulation platform. It can be used for reference in the test, research and design of train operation control system in the future.
