Test Industrial computers for Subways and Streetcars Locomotive Drive Control
One of the leading manufacturers world-wide of railway vehicles has partnered with MEN to develop a DIN rail control for re-fitting, retro-fitting and modernizing its vehicles. The computer bus and vehicle bus applied is CAN with a special safety-critical CANopen protocol. The connection to the train bus is imple-mented using a CAN-to-WTB
industrial gateway. Electronics, mechanical design and software were also developed according to strictly defined safety-critical requirements. Reliable vehicle electronics like this system plays an important role for
industrial safe and economical operation of modern railway vehicles. It controls, monitors, and diagnoses all functions during drive and brake operation, optimizes operation processes and relieves the train driver. The system is modular, for instance to be flexibly adapted to the varying requirements of locomotives or railcars with different drives (diesel-electric, diesel-hydraulic etc.). MEN supplies a French operator with diffe-rent VMEbus computers for various testing tasks on vehicles for urban public transport. The operator inspects proper functioning and safety-relevant components of systems for driverless subways for its own fleet and as a service for other operators. The vehicle electronics for subways and streetcars is also tested in the lab for electrical characteristics, isolation and robustness. Pentium
® III based computer board, analog and digital I/O, pick-ups for the route sensors and an optional MVB connection.The
industrial monitoring system of this manufacturer has the advantage of providing a response channel that allows the permanent trans-
mission of status data of the vehicles back to the control center. The demand to optimize mass transit is increasing rapidly, especially on the growing markets of Asia. Driverless subway systems are an important economic aspect. They allow a journey from station to station that is optimized for energy consumption and speed, but also a stop at the station that is precise to the centime-
ter. Depending on the project up to 500 mobile and especially stationary control and management systems are needed to monitor the train on a line.In a different application a 6U VMEbus system is the basis for the automated train control in French trains. MEN is delivering a PowerPC
Monitoring System for Driverless Subways
One of the leading manufacturers of ATO (Automated Train Operation) and safety systems on trains uses standard 19“ systems from MEN in different projects all over the world. The redundant CompactPCI
® compu-ters in single Eurocard format consist of a
® based System-On-Module (ESM™) for this project.
