ERTMS/ETCS Level 1

iCAB 1 series is an ERTMS/ETCS Level 1 solution for conventional lines (SIL4). It can be applied as an overlay to existing national ATP networks providing higher levels of safety, but providing an economical migration and early experience with the latest generation of signalling technology.

"Eurobalise" radio beacons pick up signal aspects from the trackside signals via signal adapters and telegram coders (Lineside Electronics Unit - LEU) and transmit them to the vehicle as a movement authority together with route data at fixed points. The on-board computer continuously monitors and calculates the maximum speed and the braking curve from this data.

Wayside SubsystemOnboard Subsystem

iCAB 1 series wayside subsystem is based on intermittent track-to-train communication using LEU (Lineside Equipment Unit) and Eurobalise. It can, optionally, be integrated with advanced data infill for performance enhancement. The subsystem's main components are the following:

 

Interlocking LEU Captures movement authority information from interlocking system Selects and sends telegrams to Eurobalise that contain movement authorities and track status data
Signal LEU Acquires signal status by directly interfacing light signal and measures electric current transferred from interlocking system to signal Sends telegram to Eurobalise
Eurobalise Energized by power from train antenna Stores infrastructure data as pre-formatted telegrams, specifying instance position reference, speed limits, line gradient, works on the line etc (FIXED Balise) Sends telegrams to train from LEU that contain movement permissions and trackside data (SWITCHABLE Balise)

The iCAB 1 series onboard subsystem receives and analyzes the information about the trackside status and characteristics of the movement permission sent by the Eurobalise. It automatically applies brakes if the comparison of the actual speed with the permitted speed shows that restriction of the speed must be observed. The subsystem's main components are the following:

 

RSDD Train Antenna Energizes the Eurobalise Receives the telegram sent by the trackside balises
Balise Transmission Module (BTM) Manages the Eurobalise interface Controls the supply of energy for telepowering the balises Receives and decodes the telegrams coming from the balises
European Vital Computer (EVC) Applies the Automatic Train Protection logic Acts as the Interface with the train's main functions (odometry,etc...) Manages the vital functions of the on-board subsystem and provides support for diagnostic maintenance of the on-board subsystem
Man Machine Interface (MMI) LCD touch screen panel for the control and indication functions
