Description

System overview:

The system is based on railway microcomputer interlocking, CTC, high-speed rail microcomputer interlocking, CTC3, urban rail OCC and miniaturized lines. The teaching simulation training system is shown through the sand table. It can provide a simulation training environment for dispatcher of control center, station watch keeper, duty office head, watch keeper of vehicle depot operation, dispatcher of signal building and train driver. It can provide simulation training for train dispatching signal, command system and dispatching system. It can simulate and demonstrate signal failure, explain driving rules and the duty office head’s ability of train driving and dispatching and accident handling.

System composition:

The sand table is a star structure in internal LAN, and its communication medium is twisted pair. Centering the application server and basing on database server, a three-layer client/server distributed system structure is established. It is a hardware framework system of OCC training system which has the same functions as real metro and urban rail control systems.

OCC training system is equipped with 1 database, 1 communication server, 1 vehicle depot controller, 1 remote control terminal computer for locomotive (locomotive control system is installed to remotely manipulate the train) and 1dispatching monitoring computer (to manipulate the large screen display system). 1 central control computer is installed respectively for ATS subsystem, ATP/ATO subsystem and C_LOW system (to realize operation dispatching, operation chart preparation and adjustment, command issuing and failure setting). The dispatching monitoring system can completely display the operation throughout the whole line. It can display the video images for train arrival.
