Data logger of tram's control signals
Martin Kysela · 2014
This work describes the implementation of control logical input data logger intended for use in trams transport companies as a control element of compliance with operating regulations. The device monitors up to 20 logical inputs in a variable sampling frequency. In the event of changes in at least one input, the state is written on the SD card. The system has its own real-time and USB interface for reading data and device configuration.
