Digital Command Control

Digital Command Control is a way of controlling model railway. Standard was established by NMRA. Latest versions include controlling trains and accessories and feedback from trains to the control stations.

Many devices are available from different manufacturers, however cost is high.

I will try to implement own DCC control using microcontrollers and available parts.

To control the layout I will need power supply, booster, command station, loco decoders, accessories decoders, busy detectors and a communication module for PC.

• Loco Decoder - speed, direction and acceleration management with functions of adjusting lights, playing sounds and controlling couplers
• Booster - for converting commands from command station into electrical signals
• Command station - for generating proper commands for locos and accessories, receiving feedback from busy detectors and managing layout against crashes
• PC communication module - to connect command station with PC and program layout management and locos using software interface
• Busy detector - to receive feedback from locos and organize automatic blocking system to prevent crashes
• Accessory decoder - for signals, railway crossings, construction and street lightning, figure movements and etc.
• Function decoder - for other rolling stock, to control lights and coupling

• None
