The CTCS3 Simulation And Test Platform

Ministry of Railways brings forward Chinese Train Control System which suits to the situation of our country based on demand on development of China railways at present and future. Computer simulation technology will play an important role in CTCS system requirements specification constitution and development of new train control system.The establishment of the CTCS3 simulation and test platform is based on system structure of CTCS3 and SRS, FRS of ETCS2. On-board equipment simulation subsystem is one of important subsystems in the CTCS3 simulation and test platform. It puts forward to system compartmentalization , significant functions and design of external interfaces of on-board equipment simulation subsystem by analyzing and research on system structure, functions interfaces of CTCS3 based on SRS of ETCS2. It realized software development of on-board equipment simulation subsystem and significant functions by using C++ Builder 6.0. It realized the function of computing most restrictive speed profiles and dynamic speed profiles, computing on-board odometers, ceiling speed supervision, MA speed supervision, speed comparison intervention, transmitting position report, computing end-point of MA, receiving data by balise etc. The function of on-board equipment simulation subsystem is validated and perfected by debugging together with other subsytems.
