Train Control and Monitoring System(TCMS)

Due to the multiplicity of train equipment as well as the need to establish communication between them and the exchange of information between units, the train control and management system (TCMS) is formed. The core of the TCMS is called the Vehicle Control Unit (VCU), which includes train control algorithms. TCMS is also responsible for communicating between wagons and various equipment and also monitoring them.

In general, the roles and responsibilities of TCMS are: The main and central controller of the train, and Communication and supervision of all train units.

Vehicle Control Unit is the main control system that controls all intelligent units in the vehicle. It is responsible for control, measuring, sequencing, protection, supervision and communication.

Some of the basic tasks of VCU are: Control of train propulsion and braking, Control of auxiliary converters and battery chargers, Monitoring and driver-assistance systems, Maintenance diagnosis and assistance system, Communication with control system via MVB, ETB, CAN and other communication buses, and Integration of signaling systems which are required for train operations and communication components in order to provide a comprehensive train control system
