Presentation

The system is intended to equip type 2190 compartmentalized wagons, class II, modernized by Astra Vagoane Călători Arad.

The system implements an automation network in the wagon, composed of the vehicle bus (CAN1, CAN2, RS485 CAN protocol network) and the train bus (WTB network, according to UIC556).
The control part ensures the control of access doors and intercom, the reception and processing of various digital and analog signals (battery voltage measurement, consumer charging/discharging current measurement), as well as the control of the passenger information system (information for interior and exterior displays).
The passenger information system, the UD-GW + MMI assembly, acts as the central control and configuration unit for the PIS. This system controls the display of train route data on the exterior LED displays.

Two 10.4-inch interior monitors are mounted on wagon 2190, which make up the Ethernet network.
Configuring a train's routes is done using a desktop or laptop software application, creating a database that is downloaded to one of the train's cars, which then controls the entire train via WTB.
The diagnostic part provides data about the controlled systems and collects diagnostic data from various subsystems (e.g. anti-skid, static source, access doors, intercom doors, lighting, air conditioning, PIS, WC.) of the wagon as well as diagnostic data from other wagons (up to 20 in the set) and transmits them to the train bus node which further displays them on a 6.5 inch display, located on the electrical panel door.

It signals the operating and fault states of the electrical installations on the wagon, various faults that are visually signaled on the electrical panel door using signal lamps and displayed on the 6.5-inch display, located on the electrical panel door.

The system is integrated through the design of the electrical installation and electrical panel which is also carried out by Tehmin-Brașov.
