CLEARSY is a French company whose main know-how is the design and production of certified safe systems and software applications, through the use of formal methods in industrial sectors such as urban and main-line railways, in particular the B method for the design of driverless (GoA3) or unattended (GoA4) train operation systems), automotive, energy and defence.
Since the acquisition of ERSA (European Rail Software Applications) in 2018, CLEARSY is offering products and services related to ERTMS/ETCS. Those include simulation tools for testing (on-board or trackside components or both) and for training of signalling engineers or train drivers. They include also reference tools such as a fully compliant implementation of the ETCS on-board functions and the Driver Machine Interface compliant with SIL2 requirements.
CLEARSY is actively preparing the future and works on the extensions of its products to reach a compliance with the next version of the system (Technical Specifications for Interoperability), to be issued at the end of 2022.
The CLEARSY on-board simulator (also named EVC simulator) is implementing all functions described in SUBSET-026 concerning the on-board parts, including also the DMI functions in compliance with the ERA specification. It is a functional but non safe implementation installed on its hardware or delivered in a virtual machine.
Using this On-board Simulator will allow you to prepare test cases/ scenarios and run them in real time against the simulator in a lab environment compliant with SUBSET-094 or SUBSET-111-2 and collect the juridical data generated by the simulator and analyse them
When the simulator is installed in a train, we can interface it with train and trackside equipment and acquire data generated by the trackside components of a track for the purpose of measurements.
Using this Operational Simulator will allow you to:
The true complexity of the railway system is embedded in the ERTMS/ETCS Simulation System which can be used with several built-in predefined simulation scenarios, or to give you the flexibility to define and explore own scenarios: ETCS telegrams and messages, signal aspect and point position changes required to run trains with interactive train control. We provide a set of user configurable modules:
a track and scenario editor, a train dynamics module, an EVC simulator, an ETCS Driver Machine Interface and a trackside simulator.
The value of this simulator can be further enhanced by extending it to include:
The CLEARSY Traffic Simulator is an advanced real-time system which can be used for evaluating line capacity and improvements, validating RBCs, assessing conflict detection/resolution systems, signaller training and replicating real life events.
Using the Traffic Simulator will allow you to:
The true complexity of the railway system is embedded in the Traffic Simulator which can be used with several generic trains, alternatively you can define own train and use that alongside a set of user configurable modules.
TEST BENCHES FOR
ERTMS/ETCS COMPONENTS
CLEARSY’s test benches provide:
• a proven route to validating an On Board Units and Radio Block Centre equipment against the ERTMS/ ETCS standards avoiding costly retesting at the product approval stage (compliant with the Reference Architecture defined in SUBSET 094 and SUBSET-111-2)
The CLEARSY Cross Test bench which combines both OBU and RBC test benches can be used to test EVC and RBC simultaneously for components from the same OEM or different OEMs. A comprehensive test environment can be created with the optional addition of trains running in manual or automatic mode.
