New lift safety architecture to meet PESSRAL requirements

ISBN : 978-1-4799-8171-7International audienceAs part of new lift control generation, we will analyze a transition case from an electrical/electro-mechanical components to a networked control system. The main element we focus on in the lift system is the safety chain. This paper will describe the analysis of dependability requirements (IEC 61508) for the next electronic lift control

From Model-Based to Real-Time Execution of Safety-Critical Applications: Coupling SCADE with OASIS

International audienceDeveloping embedded safety critical real-time systems and ensuring properties such as deterministic behaviour in a simple way for the application designers is a challenging task. A large number of commercial and academic real-time operating systems (RTOS) as well as model-based development environments based on synchronous languages are available. Automatic transformations from synchronous modelling languages to RTOS are important for streamlining development of real-time applications without compromising the guarantees of their safety. In this paper, we present an automatic transformation from the SCADE synchronous language into applications for the OASIS safety-oriented real-time execution platform, a multi-scale time-triggered approach. This transformation has been partially implemented and we illustrate it with an industrial case-study from the domain of medium voltage protection relays

A Service-Oriented Approach for Network-Centric Data Integration and Its Application to Maritime Surveillance

Maritime-surveillance operators still demand for an integrated maritime picture better supporting international coordination for their operations, as looked for in the European area. In this area, many data-integration efforts have been interpreted in the past as the problem of designing, building and maintaining huge centralized repositories. Current research activities are instead leveraging service-oriented principles to achieve more flexible and network-centric solutions to systems and data integration. In this direction, this article reports on the design of a SOA platform, the Service and Application Integration (SAI) system, targeting novel approaches for legacy data and systems integration in the maritime surveillance domain. We have developed a proof-of-concept of the main system capabilities to assess feasibility of our approach and to evaluate how the SAI middleware architecture can fit application requirements for dynamic data search, aggregation and delivery in the distributed maritime domain

PharOS, a multicore OS ready for safety-related automotive systems: results and future prospects

International audienceAutomotive electrical/electronic architectures need to perform more and more functions that are mapped onto many different electronic control units (ECU) because of their different safety levels or different application domains (body, powertrain, multimedia, etc.). Freedom of interference is required to comply with the upcoming ISO 26262 standard for mixing different ASIL levels on the same ECU and is also required to cope with the safe integration of software from different suppliers. PharOS provides dedicated software partitioning mechanisms as well as controlled and efficient resource sharing by construction, from the design to the implementation stages. The main features of PharOS, contributing to this property, are presented in this paper as well as the results on its application an industry-driven case study and associated future prospects

Project OASIS: The Design of a Signal Detector for the Search for Extraterrestrial Intelligence

An 8 million channel spectrum analyzer (MCSA) was designed the meet to meet the needs of a SETI program. The MCSA puts out a very large data base at very high rates. The development of a device which follows the MCSA, is presented

FutureFarm vision

This paper defines the first version of a vision of Future Farming project and also a knowledge management system used by European farms which will be designed and developed by the Future Farm project. An important part of the vision is a definition of external drivers and their influence on farm business in future. Paper is looking on a situation in three periods: short (2013), middle (2020) and long-term (2030). Our vision expects that the farming system will continuously converge to the situation of two types of farm: an industrial farm, which will guarantee both the food safety and the food security for European citizens, and multifunctional farms focused on environment protection. The recommendation proposes an architecture based on communication of interoperable services, so called Service Oriented Architecture (SOA), for easy integration of different levels and components of farm management.Farming, external drivers, future vision, knowledge management, SOA, Farm Management,
