Safe-ready COTS meeting the highest safety levels for life critical applications
A solid and flexible basis for certifiable applications in trains and signaling
The base configuration is redundant, including three VPX processor modules, interconnected by a Gigabit Ethernet switch module through a backplane. SAFe-VX does not present any single point of failure.
Due to its modular architecture, SAFe-VX offers a high level of flexibility in terms of CPU, storage and I/Os. CPU boards integrated in SAFe-VX have already been certified with safety-critical real-time hypervisor and RTOS such as PikeOS from SYSGO. The other major building blocks like the PSU and the fan trays can be offered with redundancy. In the simplest implementation, all boards are sharing the same Power Supply Unit. The boards are electrically isolated from each other by the backplane design in order to guarantee the absence of common root cause of failure. Safety I/O are optionally implemented on channel A and B through dedicated I/O card(s), mainly serial UARTs, GPIOs and analog inputs.
PikeOS hypervisor, certified RTOS from Kontron’s software partner SYSGO, Partitioning critical and non-critical application code in independent time and memory spaces
PikeOS, a well-established embedded RTOS from Kontron’s software partner SYSGO, acts as an hypervisor partitioning the critical and non-critical application code in independent time and memory spaces. The critical part of the application runs under the PikeOS hard real-time partition whereas all complex non-safety related code can run in a Linux partition, as depicted in the figure below.
SAFe-VX-DEV is immediately available at the start of the project to begin the software development with fully representative hardware. The chassis, the power supply and the cooling subsystem can then be customized depending on the requirements. When needed, two SAFe-VX platforms can be used in parallel to reach the expected availability at SIL4 level.
