| Abstract: | The data acquisition and validation subsystem of testing and assessment platform for railway block signaling system (TAPRBSS) is designed to implement data acquisition, A/D transformation and FSM signal displaying. To process frequency-shift signal is to detect and validate frequencies and amplitudes of carriers and modulated signals, which are sent out and received by block systems under test. In this way, necessary data are prepared for TAPRBSS to test and assess the function, reliability and safety of block systems. |
