SMART SOLUTIONS FORSAFE RAIL TRAFFIC

2

Growing mobility is one of the great challenges of today’s society. The increasing traffic density on the railway net-work calls for absolute safety. At the same time, investment and maintenance costs are to be kept low and the long-term availability of all components used shall be guaranteed.

With EUROLOCKING, BÄR Bahnsicherung AG has just the right product meeting these requirements.The new interlocking concept is based on the HIMax SIL4 PLC system from HIMA, Paul Hildebrandt GmbH. This meets all applicable safety requirements according to CENELEC SIL4.EUROLOCKING enables significantly lower life cycle costs than all other conventionally proprietary electronic inter-locking solutions.

CONVINCING SOLUTIONSEUROLOCKING offers many advantages:• COTS hardware (Commercial Off the Shelf), which has prov-

en itself in the process industry with the highest safety and security requirements for years

• Guaranteed useful life of at least 25 years• CENELEC SIL4 approved system• SIL4 interface modules for signals and points• SIL4 interface modules for third party devices such as track

vacancy detection devices• Standardized interface to level crossings according to Swiss

specifications• Conventional wiring oft he field equipment; no electronic

devices where not necessary• Various communication interfaces to train management and

remote control systems• High availability oft he entire system• Easy replacement of all components (hot plug & play)

With EUROLOCKING, BÄR Bahnsicherung AG has developed an electronic interlocking which is freely scalable in size. EUROLOCKING can be used on standard and narrow-gauge railways as well as mountain and urban railways.The system design enables to implement either central-ized or decentralized architectures. Based on the generic system architecture, tailor-made solutions can be designed and implemented.

The widespread use of industry standard products, which are manufactured in large quantities, offers cost advan-tages and improved quality compared to small series or single-part production.In addition, the dependence on suppliers is significantly reduced, which leads to improved readiness to deliver at lower lifecycle costs.

EUROLOCKING interlockings can be easily adapted to different conditions. The hardware design is modular and can be expanded as required. Changes to the software as well as later adaptions to the system can be implemented cost-effectively.

CPU CENTRAL PROCESSING UNITThe HIMax PLC is equipped with powerful redundant com-puters. This leads to very fast system response times. A defective CPU can be replaced during full operation with-out causing any safety issues or operational restrictions.

FAST INTERNAL SAFETY BUSEach of the two system bus modules (shown in red or green) manages one of the two internal safety-related system buses (safeethernet). The two system buses are redundant. Each system bus connects all modules and base carriers. All safetyrelated data is transmitted via these two internal system buses using a safety protocol.

EXTERNAL COMMUNICATIONThe HIMax SIL4 platform has several bus connections which can be selected as required enabling customer-specific product requirements to be met to optimally integrate the in-terlocking into existing infrastructure. The following system buses have been implemented and are available out-of-the-box for product and system connections:• FSE (Frauscher Safe Ethernet) SIL4• FSE-FSX (Frauscher safeethernet eXtendend) SIL4• PROFIsafe SIL3• MODBUS (unsafe)

This results in a high degree of integration capability.

SUCCESS THROUGH TRADITIONHIMA, Paul Hildebrandt GmbH is the leading supplier of safe and secure programmable logic controllers (PLC) in Europe. For more than 40 years, HIMA PLC systems have controlled and protected the plants of the world’s largest companies in the oil and gas as well as the chemical, phar-maceutical and power generating industry. HIMA success-fully uses the know-how gained over many years to develop new solutions for railways - BÄR and HIMA.

INTERLOCKING FUNCTIONALITYEUROLOCKING can be built with or without dwarf signals (with or without shunting routes).

SYSTEM WITH DWARF SIGNALS• Dwarf signals• Secured shunting routes• Storage for both, train routes as well as shunting routes• Automatic signal operation• Partial cancelation of routes• Special functions such as detour routes or residual route

cancelation can be implemented easily and cost-effec-tively according to customer requirements

SYSTEM WITHOUT DWARF SIGNALS• Shunting travels• Storage fort rain routes• Automatic signal operation• Partial cancelation of routes

OPERATING MODESThe interlocking can be operated in various operating modes:• Automatic remote operation• Local automatic operation• Manual remote operation• Local manual operation• Shunting operation

INTERFACE TO TRAIN MANAGEMENT SYSTEMEUROLOCKING can be operated by a train management system. There are various options to connect the different train management systems.

INTERFACES TO FIELD EQUIPMENTSIL4 interface cards enable the connection of point ma-chines, derailing devices and LED signals. The state of each device (point machine, LED signal lamp, track vacancy de-tection device) is transmitted via two redundant channels. EUROLOCKING ensures, that in any case of malfunction, the system goes into a safe state.The field equipment is wired conventionally from the cable connection rack. For larger distances, interface cards can be installed in a separate technical room and connected to the interlocking via safeethernet using optical fibre.Virtually all commercially available level crossing systems can be connected to EUROLOCKING with its standardized interface module.

EUROLOCKING is based on the experience and know-how of:
