Intelligent Architecture

In both, decentral and central architectures, Frauscher follows its philosophy of not placing any
sensible electronics on or near the track, but in protected cubicles or in buildings.

Central Architecture

Centralised architecture means the entire arrangement of axle counting components in one place
(e.g. interlocking room). The complete axle counting logic is bundled and positioned there.
Communication with the interlocking as well as configuration, diagnostics, etc. is carried out
centrally. The implementation of route blocks can be realised via copper lines or fibre optic lines
(closed networks, according to EN 50159-1).

Decentralised Architecture
Due to modern transmission technologies, decentralised arrangements are gaining in importance,
which is more economical with regard to the cable infrastructure, among other things. In contrast
to the centralised architecture, the axle counting logic is distributed to several, freely selectable
locations – decentralised. Individual interlocking clusters (field controllers; area controllers; object
