A suitable solution for every country
Since the beginning of the development of digitalised control and safety technology, Scheidt & Bachmann has pursued a modern and flexible platform strategy. The Scheidt & Bachmann platform (PSB 2000) has been continuously developed since then and forms the basis for our BUES 2000 level crossing and the ZSB 2000 interlocking. It follows the concept of distributed intelligence and allows functions and hardware to be decoupled from each other and thus to react individually to even the most varied customer requirements.
Future-proof setup
BUES 2000 is a digital level crossing protection system characterised by a modular concept with distributed intelligence in all of its components and state-of-the-art networking. This multi-computer system, which features a continuous 2v2 safety structure, makes it possible to control all processes as safe recording, processing, evaluation and output of information as well as a detailed diagnostic interface for maintenance and service purposes. Its modular structure enables the system to be quickly and flexibly adapted to each monitoring and application variant as well as other individual customer requirements.
Monitoring variants:
▪ FSÜ(S) and FSÜ(B) Track monitored
▪ Fü Remotely monitored
▪ Aut Automatic mode
▪ Hp Main signal monitored
▪ ÜS Supervision with signal BÜ 0/1 or So16a/b or EKÜS
▪ ÜSoE Supervision signalled with optimised switching on
▪ Vk Availability controlled
▪ Bed Operator-monitored
▪ Combinations (e.g. HP-Fü, HP-ÜS, FSÜ(S/B) ...)
Application variants:
▪ LZ Yellow/red light signal
▪ Bli Flashing light
▪ Dbli Double flashing light
▪ H Half-barrier
▪ HH Full barrier with 2 half-barriers
▪ V Full barrier
▪ F Footpath barrier
▪ V(A) Call barrier with attendant control
▪ V(AS) Call barrier with self-service device
Extension variants
The following maximum expansion variants are possible with the basic equipment:
▪ 64 light signals (yellow/red)
▪ 64 flashing lights (red)
▪ Barrier light
▪ 16 barrier drives
▪ User-controlled barriers
▪ 8 pedestrian acoustics (more loudspeakers possible in parallel)
▪ 2 tracks (with track sensors, signalling and hand control buttons)
▪ Interlocking interfaces
▪ 2 GFR danger-zone-free detectors The following and more applications can also be implemented:
▪ Special switching cases, such as SF-2 (WS, UW), SF-12, WFS, ESW, EVSTW, DUF and many more
▪ Time-controlled barriers (H, HH, V) and light signals (LZ, vLZ, Bli, Dbli, pedestrian acoustics) and gate dependencies
▪ Control of additional light programmes such as BüSTRA
▪ Extension to 4 tracks
Technical structure
The system core of the BUES 2000 is logically divided into three levels:
▪ Diagnostic/management level
▪ Safety level
▪ Field level
Within the safety and field levels, tasks are divided into three modules:
▪ Central module
Coordinates and controls the level crossing and provides interfaces such as SCI-LX to the interlocking
▪ Light/barrier module
Controls and monitors the road traffic components such as light points, barriers and GFRs
▪ Track module
Controls and monitors the components in the track such as train detection points, manual control boxes and signals
All subsystems communicate with one another via modern digital interfaces and guarantee fault-free operation in this critical area of the infrastructure.
Effective power supply
A safe and efficient power supply for railway safety technology has a direct influence on its availability and the operating costs of the system.
In order to ensure high availability of the power supply, batteries are used as a mains substitute. The power supply of the safety technology and the battery management is handled by the Digitrans II, which features a compact design, low weight and high efficiency.
Equipment:
▪ 1,000 to 1,400 watts of charging power for secondary DC voltages of 18 V, 24 V, 30 V, 36 V or 60 V
▪ Very compact design
▪ Low weight
▪ High efficiency (typ. 90%)
▪ Control by means of temperature-dependent charging characteristics
▪ Display for current, voltage and temperature values
▪ Operation via integrated keypad
▪ Complete compatibility with Digitrans I
Further features:
▪ Adjustable maximum current limit
▪ Adjustable charging time at gassing voltage
▪ Display of battery voltage even during mains failure
▪ Mains failure counter
▪ Temperature display
▪ Fault output via relay contact
▪ Option to cascade multiple DIGITRANS II in case of increased power demand
▪ Two relay contacts as external interface, e.g. voltage monitoring (LFÜ) or mains failure
▪ External CAN bus connection (e.g. diagnostics)
▪ 1-kW class unit without active fan
