Study Notes
Control System (SIBAS 32)
- The control system (SIBAS 32) comprises several units: Central Control Unit (CCU), Traction Control Unit (TCU), Brake Control Unit (BCU), Man-Machine Interface (MMI), Multi-Vehicle Bus (MVB), and SIBAS Klip Station (SKS).
- The control technology is designed redundantly with two CCUs per train, located in the driver's cab.
- CCUs control the entire train, including the display.
- Units and vehicle components connect via a Multi-Vehicle Bus (MVB). The MVB has redundant lines (A and B) for backup. If line A fails, system will automatically switch to backup line B, allowing degraded operation.
- A degraded operating mode (RDM) allows track clearing if the MVB fails.
- Auxiliary lamps activate in the RDM, and the display is deactivated.
- Switches and other consumers connect via input/output stations (KLIP stations).
- KLIP stations minimize the length of control lines to the CCU.
Traction Controls
- The vehicle is a three-phase vehicle controlled by a TCU.
- The TCU receives propulsion and braking instructions (electronic brake).
- Information from the TCU is transmitted to the current converter.
- A TCU failure prevents the unit from autonomous operation but isn't a safety concern if the vehicle is part of a train.
Brake Control
- All braking components directly affecting the brakes are connected to the MVB.
- Brake commands, initiated by joystick/brake lever, are calculated and transmitted to Brake Control Units (BCUs) and Traction Control Units (TCUs).
- A pneumatic Wheel Slip Protection (WSP) isn't available for this vehicle. Wheel slip prevention is limited to driven axles of motor cars.
- In case of brake malfunction, the driver can use emergency brake function, and the TCU can, if necessary, take over the functions of the faulty brake control unit (BCU).
Automatic Vigilance Device
- The automatic vigilance device activates automatically if the vigilance monitoring button is released while travelling.
- The device applies brakes and shuts off the power of the train.
- This function in disabled when speed is below 5 km/h.
- The brakes are automatically engaged even in degraded modes (like rescue drive mode) when speed is below 5 km/h.
Display Support
- A Man-Machine Interface (MMI) provides real-time display of important system functions (e.g. train number, date, time, screen designations, short/long messages, etc.)
- Colored icons represent the operational status of the train's components.
- Drivers can identify malfunctions by visually examining the display.
- Error messages provide guidance for remedial actions.
Different MMI Screens
- There are various MMI screens (Top level screen, Unit Screen), showing information such as the train number, date, time, main screen, message text, etc. These screens use colored icons to visually represent the status and signals.
