Projetar sistemas de controle e robóticos como sistemas descentralizados autônomos introduz um novo grau de flexibilidade na fabricação e na aplicação de tais sistemas. Esta flexibilidade é necessária para que os sistemas funcionem em ambientes que não são totalmente previsíveis e que podem mudar de forma dinâmica. Neste artigo, apresentamos um novo conceito para comunicação em tempo real que suporta essa flexibilidade, ao mesmo tempo que preserva garantias de tempo real para comunicação difícil em tempo real. O conceito foi projetado para funcionar em barramentos de acesso múltiplo. Em particular, consideramos sua aplicação em redes locais sem fio e barramentos de campo. O conceito atende aos requisitos de comunicação em tempo real, tempo real suave e comunicação em tempo não real. Para isso, estendemos a abordagem TDMA (acesso múltiplo por divisão de tempo) para comunicação em tempo real acionada por tempo pelo conceito de canais compartilhados que suportam comunicação acionada por eventos e coexistem com canais rígidos em tempo real. Uma primeira implementação do conceito foi realizada no contexto do barramento CAN.

Abstract: Designing control and robotic systems as autonomous decentralized systems introduces a new degree of flexibility in the manufacturing and in the application of such systems. This flexibility is required for the systems to work in environments that are not totally predictable and that can change dynamically. In this paper, we present a new concept for real-time communication that supports this flexibility while still preserving real-time guarantees for hard real-time communication. The concept is designed to work on multiple-access busses. In particular, we consider its application on wireless local area networks and field-busses. The concept addresses requirements of hard-real time, soft real-time and non real-time communication. For this, we extend the TDMA (time- division multiple-access) approach for time-triggered hard-real time communication by the concept of shared channels that support event-triggered communication and coexist with hard real-time channels. A first implementation of concept has been carried out in the context of the CAN-bus.
