Real Time Simulator
The Real Time Simulator, RTS 1.4 is a speciality test system designed to test Bombardier Transportation’s MITRAC Series Digital Control Units. This system is used to control the dSPACE signal generation hardware which generates several analog and digital events, and helps to carry out real time simulation tests. The RTS interface is designed to allow quick changeover between different project models by making use of swappable pre-wired modules. The Drive Control Unit – DCU-II – receives the signals from RTS 1.4 in an amplified or conditioned form, and perceives them as inputs from transducers, etc. The program in DCU-II takes decisions on the prevailing real time condition and generates responses accordingly. The integrity of stimulus and response helps to establish that the system is performing as expected. The system mainly consists of dSPACE as a simulation hardware, dSPACE wire wrap board, CREST Interface, DCU-II wire wrap board, and DCU-II as a Device-Under-Test.
