FVB TCMS

FVB TCMS for diesel locomotive applications

Train control and management system
This System consists of 4 parts that are described below

PLC

Electronic governor with load regulator

Throttle control

MMI Display (Man Machine Interface)

Due to the complexity of reverse engineering to be able to make analogic system interface it is considered a better option to make the total change of the TCMS. A new fully digital TCMS (Train Control and Management System) will handle all communications in digital format in Modbus Ethernet. This system will control all train operations and the safety loop (Interlocks) such as acceleration, braking and safety protocols. The system will have the advantage of being current technology, fully digital and modular, so this will eliminate a lot of wiring and electromechanical equipment which require a lot of maintenance, this system will handle the speed, direction, dynamic braking controls, excitation, compressor control, wheel slip, etc.

Functions

• Input and output of data from analog, digital and frequency I/O sources directly to the train computer (TCMS processor) and can lead to reduced cabling and therefore cost savings.
• Locomotive system Diagnostic
• Intercommunication with MMI in both ways
• Dynamic Brake and traction control (wheelslip)
• Security applications (Dead man control, emergency stop, staring protocols, etc.)
• Fleet maintenance management (The TCMS know the current operating hours of each major component and can issue a report that can be linked to the stock MRP to request the spares required for its next maintenance and prepare the maintenance program.

• Air conditioning management
• Management of the CCTV system in MMI
• Battery charge monitoring in MMI
• Position of the throttle lever and acceleration or braking ratio applied in the MMI
• Monitoring local and remote alarms on the MMI
• Torque and engine flow control.
• Interface with vehicle control.
• Drive monitoring, protection and diagnostics.
• Supervision of motors, brake resistors, protection and diagnostics.
• Management of train communication and infrastructure (Additional hardware and software required)

On the hardware side the TCMS is modular and build by standard PLC parts that can be bought worldwide in the industrial PLC market, so spares are available worldwide with immediate delivery or very short led times, we own the intellectual property and engineering, that means we develop software not hardware. This means that you we can develop custom systems that fit your needs perfectly by simply selecting the modules and interfaces you need; you ensure that the system meets all your demands and is cost-effective. Systems can be easily upgraded with additional modules as needs arise.

In general, the FVB Control Systems will be providing the following benefits

• Improved locomotive performance
• Reduction/elimination of high maintenance components
• Improvement in tractive effort under all weather conditions
• Advanced integrated diagnostics with real-time and historical analysis
• Superior wheel slip control capabilities in power and DB operation
• Replacement of old analog modules, such as Dash 2 modules (where applicable)
• Enhanced main alternator/generator and motor protection
• Locomotive Maintenance cycle management
• 24 / 7 Customer Service Desk

MMI (Man-Machine Interface)

The integration of MMI displays to the TCMS is the best option for modernization of locomotives since on the original design there are many obsolete equipment’s that required a lot of wiring and a lot of analog inputs and outputs so the best option is to eliminate them and convert them into digital signals on Ethernet. The digital displays were chosen because of the screen-operated protection features, as well as their hardware features available for the custom interface system as it is dedicated hardware for application this application.
