SACDT ADK Wagon Class I, II
The system implements an automation network in the wagon, composed of the vehicle bus (CAN network, CANopen protocol) and the train bus (WTB network, according to UIC556).
The control part ensures the control of the doors, lighting, minimum voltage relay (protection against battery discharge when the static source no longer works), the reception and processing of various analog signals (battery voltage, charging current, three-phase system voltage values), as well as the control of the passenger information system (GPS, information for interior and exterior displays, as well as the generation of audio messages).
The diagnostic part provides data about the controlled systems and collects diagnostic data from various subsystems (for example: climate control unit).
The system is integrated through the design of the electrical installation and the electrical panel which is also carried out by Tehmin-Brasov.
