Presentation

The system is intended to equip double-decker passenger cars (both floors of class II) type 26-16, modernized by SC ELECTROPUTERE VFU SA Paşcani.
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 UIC 556).
The control part ensures the control of the doors, lighting, the 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, etc.), as well as the control of the passenger information system (information for interior and exterior displays).
The diagnostic part provides data about the controlled systems and collects diagnostic data from various subsystems (for example: the air conditioning and access door control unit) and transmits it to the first class wagon for centralization.

The system is integrated by redesigning the electrical installation and the electrical panel, which is also carried out by SC TEHMIN-BRAŞOV SRL.
