Embedded engineering for transportation
On-board and wayside devices for rail and public transport - telematics, monitoring and passenger systems that work in a harsh environment for many years.
Sector challenges
Harsh environment
Vibration, wide temperature ranges and supply transients set the requirements for hardware and firmware.
Connectivity on the move
Cellular links with gaps: data is buffered and sent when coverage returns, positions come from GNSS.
Long lifecycle
Vehicles stay in service for decades, so obsolescence and updates are planned from the start - see legacy modernization.
Security
Connected vehicles and wayside equipment need secure communication and secure updates.
Our approach
- 01
Data acquisition
Reading vehicle buses and sensors with firmware built for the environment. See firmware development.
- 02
Telematics
Gateways that send data to the operator over cellular links - see IoT & connectivity.
- 03
Edge processing
Condition monitoring on board, so maintenance can be planned before failures.
- 04
Lifecycle
Updates, component replacements and support for the whole service life of the fleet.
