Train Control & Management Systems (TCMS)
What the central nervous system does for humans, the TCMS does for rail vehicles and trains. This stands for Train Control & Management System - like a large control center, it monitors and connects the vehicle subsystems with each other and with the superordinate train control system.
In vehicle automation, everything depends on the control system
A simple scenario: The train arrives at a station, the driver releases the doors after the train has come to a standstill. Passengers press the buttons, doors open, sliding steps extend. Ideally, the door system notifies the air-conditioning system of the open entrances. The air-conditioning systems briefly reduce their output - so that they do not blow the cold or warm air out onto the platform. Once all passengers have disembarked and boarded, the doors close. The anti-trap system is ready. Not until all doors are securely closed will the TCMS release the braking system to allow the train driver to depart. Hundreds of individual control and monitoring processes are required for this simple scenario alone.
Perfectly matched Selectron systems
The mastermind that knows how to coordinate all these processes is called the Train Control & Monitoring System (TCMS). It establishes communication between the superordinate train control system and subsystems such as propulsion systems, brakes, doors, air conditioning systems, illumination or sanitary facilities and connects them to the superordinate vehicle control system.
As one of the world's leading TCMS developers, Selectron provides you with excellently harmonized system solutions for automating your rail vehicles. We are specialized in end-to-end, customer-friendly control, network and communications technology, including customized software. Selectron delivers the optimum system architecture that is so crucial for high vehicle availability of your vehicles in operation.
Quality products meeting all current standards
With a focus on safety and security, the TCMS portfolio includes freely programmable controllers (PLCs) as vehicle control units, flexible subsystem controllers such as the Smartio® Remote I/O System as well as Remote Input/Output Modules (RIOM). Functional modules, efficient and transparent software tools and driver's cab displays (HMI) complete the portfolio.
- Customized individual solutions: Thanks to the flexibility of its organization and the open structure of its end-to-end control system, Selectron creates a solution tailored precisely to your requirements.
- Clear edge: With the separation of safety-relevant and non-safety-relevant applications in one device, Selectron structures your TCMS architectures and simplifies vehicle homologation. Generic and freely programmable, as well as highly flexible SIL CPUs shorten the homologation process for new vehicles and modernization projects even further.
- Innovative architectures: Independent and mutually non-interacting SIL applications on a single control hardware reduce recurring equipment costs.
Individual requirements need individual solutions. This is why there is not one single Train Control & Management System (TCMS) for the control of trains and their subsystems. The requirement must rather be: The optimal TCMS is customized to meet the very specific requirements of the automated rail vehicle.
The advancing digitalization connects individual participants both within the vehicle (TCMS, passenger information systems, passengers), but above all, with the outside world (rail vehicles, smart data, Cloud systems). As a consequence, trains are no longer closed systems. More than that, the vehicles themselves become the central part of a much more comprehensive overall system. In turn, however, this results in security vulnerabilities with potentially serious consequences. Sophisticated solutions for cybersecurity are in demand - at Selectron, you can get them from a designated specialist.
Protecting rail vehicles and their numerous subsystems effectively against cyberattacks is a complex task. Selectron meets it with a no less complex defense-in-depth concept: It starts with primary defense measures, such as identity and access control, extends to security certificates and public key infrastructures (PKI), and continues with the rail-specific early warning system Threat Detection Solution (TDS). With its expertise in governance, risk management and compliance, Selectron acts as a global cybersecurity Center of Competence for all Knorr-Bremse AG rail companies.
Initially deployed mainly for passenger comfort functionalities, Ethernet technology also advanced to the standard in train control. This results in increased demands on communication performance – both in terms of bandwidths and the management of the communication itself. Extremely precise control of the networks is becoming indispensable. Selectron is meeting the demands with a new generation of Ethernet routers, Ethernet-managed switches, a new converter family, communication cards, and relays.
