Systems actionneurs

Integrated design, software and electronics development.

From architecture to tests, IT Link supports you in the design of robust and secure embedded systems.

IT Link conçoit, spécifie et intègre des interfaces physique-numérique à base de capteurs et d’actionneurs. Nous intervenons sur l’ensemble de la chaîne, du choix des capteurs jusqu’à l’application métier, en passant par l’actionneur, le câblage, l’électronique, les systèmes embarqués et la connectivité. Notre objectif est de garantir une mesure fiable, une commande maîtrisée et une donnée exploitable.

Le rôle du capteur et de l'actionneur dans un système

Dans un système connecté, la chaîne fonctionnelle repose généralement sur trois niveaux :

  • Le capteur mesure une grandeur physique et fournit une information exploitable.
  • La partie commande traite cette information et prend une décision.
  • L’actionneur applique cette décision sur le procédé.

Ce schéma se retrouve aussi bien sur une machine de production que sur un véhicule, une installation énergétique ou un équipement de bâtiment. C’est sur cette architecture que s’appuie l’ingénierie proposée par IT Link.

Automobile
In the automotive industry, embedded systems range from the driver assistance computer to the connected vehicle. Depending on the need, this may include sensor fusion for ADAS, battery management and power electronics, CAN, LIN, and Ethernet communication gateways with secure software updates, as well as embedded diagnostics and telemetry. Architectures and software are sized on a case-by-case basis for real-time determinism, cybersecurity and operational safety, in line with standards such as ISO 26262 and AUTOSAR.

Aeronautics and space
Avionics and space programs require robust and traceable embedded systems. The scope can cover on-board computers, payloads and TM/TC chains, rugged software development, latency measurement and deterministic processing, and integration with ground stations. Development and test evidence is adapted to the context and reference standards, including DO-178C, DO-254, and ECSS, taking into account environmental and energy constraints.
Defense
In terrestrial, naval or aerial environments, rugged embedded systems must combine resilience and discretion. Achievements may relate to mission processing, secure and encrypted communications, navigation and sensor functions, or interfaces with existing subsystems. Hardware and software hardening, confidentiality, and life cycle control are handled according to program requirements and applicable standards, for example MIL-STD, STANAG, and AQAP.

Energy
For smart grids and the integration of distributed assets, embedded systems address measurement, local control, and the edge.
Typical examples: network sensors and RTUs secured to SCADA, meters and low-power connected objects in LPWAN, edge gateways that aggregate data, apply local rules and ensure signed updates.
The architecture favors energy autonomy, robustness, supervision and operational security, in the spirit of industry practices such as IEC 62443.

Railway
On board rolling stock and infrastructure, embedded systems serve for traction, signaling, event recording, telemetry, and embedded IP architectures. The HIL and SIL test chains, the traceability of requirements to the tests and the preparation of files are organized to facilitate qualification according to EN 50126, EN 50128 and EN 50129, with a constant objective of reliability and availability.
Industry 4.0
As close as possible to machines and lines, embedded systems aim for performance and availability. The use cases cover real-time controllers, embedded vision for quality control, Linux industrial gateways connecting Modbus, Profinet or OPC UA to the SI, and autonomous sensors for condition monitoring. The architecture focuses on I/O determinism, EMC immunity, network security, and maintainability to support productivity.

High Tech
On the high tech side, the support of embedded system platforms ranges from the bring-up of new SoCs and cards to the creation of drivers, BSP and SDKs, through the optimization of network stacks and performances, then the industrialization of a POC into a usable product with CI/CD, packaging, OTA updates and long-term support. The scope is defined jointly with the teams to accelerate the roadmap within the set costs and deadlines.
Medical
For medical devices and health gateways, embedded systems must combine security, traceability and confidentiality. Achievements range from wearables and portable instruments with embedded software to secure gateways to hospital information systems. Development, testing, and risk management activities align with device class and regulatory requirements, including IEC 62304, ISO 13485, and ISO 14971, in order to facilitate licensing and operation.
Automotive
In the automotive industry, embedded systems range from driver assistance computers to connected vehicles. Depending on requirements, this may include sensor fusion for ADAS, battery management and power electronics, CAN, LIN, and Ethernet communication gateways with secure software updates, as well as on-board diagnostics and telemetry. Architectures and software are scaled on a case-by-case basis for real-time determinism, cybersecurity, and operational safety, in line with standards such as ISO 26262 and AUTOSAR.

Technologies and tools

Une fois la chaîne capteur–actionneur mise en place, la valeur se situe dans la donnée produite et son exploitation. IT Link apporte son expertise sur trois volets complémentaires :

  • Les systèmes embarqués : Développement logiciel pour prétraiter les signaux au plus près du terrain (filtrage, détection, agrégation).
  • La connectivité : Intégration de bus de terrain, protocoles industriels, liaisons IoT ou cellulaires (4G/5G), interfaçage avec les systèmes d’information.
  • La valorisation de la donnée : Conception de tableaux de bord, vues de supervision et fonctionnalités de maintenance prédictive pour anticiper les dérives.

FAQS

  • Non. On les retrouve dans l’industrie, mais aussi dans les transports, l’énergie, le bâtiment et les objets connectés. Dès qu’un système mesure une grandeur physique et agit en conséquence, il met en jeu ces composants.

  • Yes. Partitioning (hard functions under RTOS, services under Linux/Autosar Adaptive), secure IPC, memory isolation and graceful reboot to maintain reliability.

  • Traceability of requirements→design→tests, formal proofreading, adapted coverage (up to MC/DC depending on field), configuration management and audit-ready files.

  • Secure boot, secrets in SE/TPM, signed OTA, OTA, SBOM, CVE management, hardening, intrusion tests; threat modeling from the architecture of your embedded systems.
